In this study, we combine different approaches to understand the roles that Dscam1 plays in fitness-related contexts in two model insect species. Contrary to our expectations, we found no short-term modulation of Dscam1 gene expression after haemocoelic or oral bacterial exposure in Tribolium castaneum, or after haemocoelic bacterial exposure in Drosophila melanogaster. Furthermore, RNAi-mediated Dscam1 knockdown and subsequent bacterial exposure did not reduce T. castaneum survival. However, Dscam1 knockdown in larvae resulted in adult locomotion defects, as well as dramatically reduced fecundity in males and females. We suggest that Dscam1 does not always play a straightforward role in immunity, but strongly influences behaviour and fecundity.

The status of these two forms has been the subject of considerable controversy. Populations of the two forms are usually spatially distinct, but at Răscruci in Romania both forms occur on the same site (syntopically). We examined the genetic differentiation between the two forms using eight microsatellite markers, and compared with a nearby hygric site, Şardu. Our results showed that while the two forms are strongly differentiated at Răscruci, it is the xeric form there that is most similar to the hygric form at Şardu, and Bayesian clustering algorithms suggest that these two populations have exchanged genes relatively recently. We found strong evidence for population substructuring, caused by high within host ant nest relatedness, indicating very limited dispersal of most ovipositing females, but not association with particular host ant species. Our results are consistent with the results of larger scale phylogeographic studies that suggest that the two forms represent local ecotypes specialising on different host plants, each with a distinct flowering phenology, providing a temporal rather than spatial barrier to gene flow.","lang":"eng"}],"type":"journal_article","doi":"10.7717/peerj.1865","language":[{"iso":"eng"}],"oa":1,"tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"quality_controlled":"1","month":"01","author":[{"full_name":"Tartally, András","first_name":"András","last_name":"Tartally"},{"first_name":"Andreas","last_name":"Kelager","full_name":"Kelager, Andreas"},{"id":"393B1196-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-3712-925X","first_name":"Matthias","last_name":"Fürst","full_name":"Fürst, Matthias"},{"full_name":"Nash, David","first_name":"David","last_name":"Nash"}],"volume":2016,"date_updated":"2021-01-12T06:50:41Z","date_created":"2018-12-11T11:51:59Z","year":"2016","department":[{"_id":"SyCr"}],"publisher":"PeerJ","publication_status":"published","publist_id":"5767","file_date_updated":"2020-07-14T12:44:53Z","article_number":"1865"},{"day":"22","month":"01","article_processing_charge":"No","oa":1,"main_file_link":[{"url":"https://doi.org/10.5061/dryad.4b565","open_access":"1"}],"citation":{"mla":"Mcmahon, Dino, et al.

RNA viruses associated with honeybees represent a potential threat to other insect pollinators, but the extent of this threat is poorly understood. This study aims to attain a detailed understanding of the current and ongoing risk of emerging infectious disease (EID) transmission between managed and wild pollinator species across a wide range of RNA viruses. Within a structured large-scale national survey across 26 independent sites, we quantify the prevalence and pathogen loads of multiple RNA viruses in co-occurring managed honeybee (Apis mellifera) and wild bumblebee (Bombus spp.) populations. We then construct models that compare virus prevalence between wild and managed pollinators. Multiple RNA viruses associated with honeybees are widespread in sympatric wild bumblebee populations. Virus prevalence in honeybees is a significant predictor of virus prevalence in bumblebees, but we remain cautious in speculating over the principle direction of pathogen transmission. We demonstrate species-specific differences in prevalence, indicating significant variation in disease susceptibility or tolerance. Pathogen loads within individual bumblebees may be high and in the case of at least one RNA virus, prevalence is higher in wild bumblebees than in managed honeybee populations. Our findings indicate widespread transmission of RNA viruses between managed and wild bee pollinators, pointing to an interconnected network of potential disease pressures within and among pollinator species. In the context of the biodiversity crisis, our study emphasizes the importance of targeting a wide range of pathogens and defining host associations when considering potential drivers of population decline.","lang":"eng"}],"status":"public","title":"Data from: A sting in the spit: widespread cross-infection of multiple RNA viruses across wild and managed bees","department":[{"_id":"SyCr"}],"publisher":"Dryad","year":"2016","_id":"9720","user_id":"6785fbc1-c503-11eb-8a32-93094b40e1cf","date_created":"2021-07-26T09:14:19Z","date_updated":"2023-02-23T10:17:25Z","oa_version":"Published Version","author":[{"first_name":"Dino","last_name":"Mcmahon","full_name":"Mcmahon, Dino"},{"last_name":"Fürst","first_name":"Matthias","orcid":"0000-0002-3712-925X","id":"393B1196-F248-11E8-B48F-1D18A9856A87","full_name":"Fürst, Matthias"},{"full_name":"Caspar, Jesicca","first_name":"Jesicca","last_name":"Caspar"},{"first_name":"Panagiotis","last_name":"Theodorou","full_name":"Theodorou, Panagiotis"},{"full_name":"Brown, Mark","last_name":"Brown","first_name":"Mark"},{"last_name":"Paxton","first_name":"Robert","full_name":"Paxton, Robert"}],"related_material":{"record":[{"relation":"used_in_publication","status":"public","id":"1855"}]}},{"department":[{"_id":"SyCr"}],"publisher":"Royal Society, The","publication_status":"published","acknowledgement":"This work was supported by the Federal Ministry of Food, Agriculture and Consumer Protection (Germany): Fit Bee project (grant 511-06.01-28-1-71.007-10), the EU: BeeDoc (grant 244956), iDiv (2013 NGS-Fast Track grant W47004118) and the Insect Pollinators Initiative (IPI grant BB/I000100/1 and BB/I000151/1).

Using laboratory experiments and a systematic field survey, we demonstrate that an emerging DWV genotype (DWV-B) is more virulent than the established DWV genotype (DWV-A) and is widespread in the landscape. Furthermore, we show in a simple model that colonies infected with DWV-B collapse sooner than colonies infected with DWV-A. We also identify potential for rapid DWV evolution by revealing extensive genome-wide recombination in vivo. The emergence of DWV-B in naive honeybee populations, including via recombination with DWV-A, could be of significant ecological and economic importance.

Using laboratory experiments and a systematic field survey, we demonstrate that an emerging DWV genotype (DWV-B) is more virulent than the established DWV genotype (DWV-A) and is widespread in the landscape. Furthermore, we show in a simple model that colonies infected with DWV-B collapse sooner than colonies infected with DWV-A. We also identify potential for rapid DWV evolution by revealing extensive genome-wide recombination in vivo. The emergence of DWV-B in naive honeybee populations, including via recombination with DWV-A, could be of significant ecological and economic importance. Our findings emphasize that knowledge of pathogen genetic identity and diversity is critical to understanding drivers of species decline.","lang":"eng"}],"main_file_link":[{"open_access":"1","url":"https://doi.org/10.5061/dryad.cq7t1"}],"citation":{"apa":"Mcmahon, D., Natsopoulou, M., Doublet, V., Fürst, M., Weging, S., Brown, M., … Paxton, R.

Yet, to date, the underlying genetic mechanisms and associated trait functions that are unique to rapid coevolutionary change are generally unknown. We here combined experimental evolution of the bacterial biocontrol agent Bacillus thuringiensis and its nematode host Caenorhabditis elegans with large-scale phenotyping, whole genome analysis, and functional genetics to demonstrate the selective benefit of pathogen virulence and the underlying toxin genes during the adaptation process. We show that: (i) high virulence was specifically favoured during pathogen–host coevolution rather than pathogen one-sided adaptation to a nonchanging host or to an environment without host; (ii) the pathogen genotype BT-679 with known nematocidal toxin genes and high virulence specifically swept to fixation in all of the independent replicate populations under coevolution but only some under one-sided adaptation; (iii) high virulence in the BT-679-dominated populations correlated with elevated copy numbers of the plasmid containing the nematocidal toxin genes; (iv) loss of virulence in a toxin-plasmid lacking BT-679 isolate was reconstituted by genetic reintroduction or external addition of the toxins.We conclude that sustained coevolution is distinct from unidirectional selection in shaping the pathogen's genome and life history characteristics.

Nevertheless, basic knowledge about such parameters is often missing from the literature, even for well-studied bacteria, such as Bacillus thuringiensis, an endospore-forming insect pathogen, which infects its hosts via the oral route. To characterize bacterial replication success, we made use of an experimental oral infection system for the red flour beetle Tribolium castaneum and developed a flow cytometric assay for the quantification of both spore ingestion by the individual beetle larvae and the resulting spore load after bacterial replication and resporulation within cadavers. On average, spore numbers increased 460-fold, showing that Bacillus thuringiensis grows and replicates successfully in insect cadavers. By inoculating cadaver-derived spores and spores from bacterial stock cultures into nutrient medium, we next investigated outgrowth characteristics of vegetative cells and found that cadaver- derived bacteria showed reduced growth compared to bacteria from the stock cultures. Interestingly, this reduced growth was a consequence of inhibited spore germination, probably originating from the host and resulting in reduced host mortality in subsequent infections by cadaver-derived spores. Nevertheless, we further showed that Bacillus thuringiensis transmission was possible via larval cannibalism when no other food was offered.

The articles that follow cover research on societies ranging from insects to humans. Variation in measures of fitness (i.e. survival and reproduction) has been linked to various aspects of sociality in humans and animals alike, and variability in individual health and condition has been recognized as a key mediator of these relationships. Viewed from a broad evolutionary perspective, the evolutionary transitions from a solitary lifestyle to group living have resulted in several new health-related costs and benefits of sociality. Social transmission of parasites within groups represents a major cost of group living, but some behavioural mechanisms, such as grooming, have evolved repeatedly to reduce this cost. Group living also has created novel costs in terms of altered susceptibility to infectious and non-infectious disease as a result of the unavoidable physiological consequences of social competition and integration, which are partly alleviated by social buffering in some vertebrates. Here, we define the relevant aspects of sociality, summarize their health-related costs and benefits, and discuss possible fitness measures in different study systems. Given the pervasive effects of social factors on health and fitness, we propose a synthesis of existing conceptual approaches in disease ecology, ecological immunology and behavioural neurosciences by adding sociality as a key factor, with the goal to generate a broader framework for organismal integration of health-related research."}],"issue":"1669","main_file_link":[{"url":"http://www.ncbi.nlm.nih.gov/pmc/articles/PMC4410382/","open_access":"1"}],"oa":1,"external_id":{"pmid":["25870402"]},"quality_controlled":"1","doi":"10.1098/rstb.2014.0116","language":[{"iso":"eng"}],"month":"05","acknowledgement":"We thank the German Research Foundation (DFG), the Ministry of Science and Culture of Lower-Saxony (MWK Hannover) and the German Primate Centre (DPZ) for their support of the 9.

Nevertheless, theoretical investigations of their particular life history are scarce. We develop a model that takes into account the main distinguishing features between traditionally studied diseases and obligate killing pathogens, like the (biocontrol-relevant) insect-pathogenic fungi Metarhizium and Beauveria. First, obligate killing entomopathogenic fungi produce new infectious particles (conidiospores) only after host death and not yet on the living host. Second, the killing rates of entomopathogenic fungi depend strongly on the initial exposure dosage, thus we explicitly consider the pathogen load of individual hosts. Further, we make the model applicable not only to solitary host species, but also to group living species by incorporating social interactions between hosts, like the collective disease defences of insect societies. Our results identify the optimal killing rate for the pathogen that minimises its invasion threshold. Furthermore, we find that the rate of contact between hosts has an ambivalent effect: dense interaction networks between individuals are considered to facilitate disease outbreaks because of increased pathogen transmission. In social insects, this is compensated by their collective disease defences, i.e., social immunity. For the type of pathogens considered here, we show that even without social immunity, high contact rates between live individuals dilute the pathogen in the host colony and hence can reduce individual pathogen loads below disease-causing levels."}],"page":"54 - 64","citation":{"mla":"Novak, Sebastian, and Sylvia Cremer. “Fungal Disease Dynamics in Insect Societies: Optimal Killing Rates and the Ambivalent Effect of High Social Interaction Rates.” Journal of Theoretical Biology, vol. 372, no. 5, Elsevier, 2015, pp. 54–64, doi:10.1016/j.jtbi.2015.02.018.","short":"S.

RNA viruses associated with honeybees represent a potential threat to other insect pollinators, but the extent of this threat is poorly understood. This study aims to attain a detailed understanding of the current and ongoing risk of emerging infectious disease (EID) transmission between managed and wild pollinator species across a wide range of RNA viruses. Within a structured large-scale national survey across 26 independent sites, we quantify the prevalence and pathogen loads of multiple RNA viruses in co-occurring managed honeybee (Apis mellifera) and wild bumblebee (Bombus spp.) populations. We then construct models that compare virus prevalence between wild and managed pollinators. Multiple RNA viruses associated with honeybees are widespread in sympatric wild bumblebee populations. Virus prevalence in honeybees is a significant predictor of virus prevalence in bumblebees, but we remain cautious in speculating over the principle direction of pathogen transmission. We demonstrate species-specific differences in prevalence, indicating significant variation in disease susceptibility or tolerance. Pathogen loads within individual bumblebees may be high and in the case of at least one RNA virus, prevalence is higher in wild bumblebees than in managed honeybee populations. Our findings indicate widespread transmission of RNA viruses between managed and wild bee pollinators, pointing to an interconnected network of potential disease pressures within and among pollinator species. In the context of the biodiversity crisis, our study emphasizes the importance of targeting a wide range of pathogens and defining host associations when considering potential drivers of population decline.","lang":"eng"}],"issue":"3","status":"public","ddc":["570"],"title":"A sting in the spit: Widespread cross-infection of multiple RNA viruses across wild and managed bees","intvolume":" 84","user_id":"6785fbc1-c503-11eb-8a32-93094b40e1cf","_id":"1855","file":[{"relation":"main_file","file_id":"5350","checksum":"542a0b9b07e78050a81b35f26f0b82da","date_created":"2018-12-12T10:18:29Z","date_updated":"2020-07-14T12:45:19Z","access_level":"open_access","file_name":"IST-2016-460-v1+1_McMahon_et_al-2015-Journal_of_Animal_Ecology.pdf","file_size":1823045,"content_type":"application/pdf","creator":"system"}],"oa_version":"Published Version","pubrep_id":"460","month":"03","quality_controlled":"1","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"oa":1,"external_id":{"pmid":["25646973"]},"language":[{"iso":"eng"}],"doi":"10.1111/1365-2656.12345","file_date_updated":"2020-07-14T12:45:19Z","publist_id":"5245","publication_status":"published","publisher":"Wiley","department":[{"_id":"SyCr"}],"year":"2015","acknowledgement":"We thank J.R. de Miranda, L.

We use garden ants (Lasius neglectus) and the fungal pathogen Metarhizium as a model system to study how pathogen presence affects self-grooming and allogrooming between exposed and healthy individuals. We develop an epidemiological SIS model to explore how experimentally observed grooming patterns affect disease spread within the colony, thereby providing a direct link between the expression and direction of sanitary behaviours, and their effects on colony-level epidemiology. We find that fungus-exposed ants increase self-grooming, while simultaneously decreasing allogrooming. This behavioural modulation seems universally adaptive and is predicted to contain disease spread in a great variety of host–pathogen systems. In contrast, allogrooming directed towards pathogen-exposed individuals might both increase and decrease disease risk.

Here, we studied the novel association between the invasive garden ant Lasius neglectus and its fungal ectosymbiont Laboulbenia formicarum for potential costs and benefits. We tested ants with different Laboulbenia levels for their survival and immunity under resource limitation and exposure to the obligate killing entomopathogen Metarhizium brunneum. While survival of L. neglectus workers under starvation was significantly decreased with increasing Laboulbenia levels, host survival under Metarhizium exposure increased with higher levels of the ectosymbiont, suggesting a symbiont-mediated anti-pathogen protection, which seems to be driven mechanistically by both improved sanitary behaviours and an upregulated immune system. Ants with high Laboulbenia levels showed significantly longer self-grooming and elevated expression of immune genes relevant for wound repair and antifungal responses (β-1,3-glucan binding protein, Prophenoloxidase), compared with ants carrying low Laboulbenia levels. This suggests that the ectosymbiont Laboulbenia formicarum weakens its ant host by either direct resource exploitation or the costs of an upregulated behavioural and immunological response, which, however, provides a prophylactic protection upon later exposure to pathogens.

We here tested whether experience gained by repeated tending of low-level fungus-exposed (Metarhizium robertsii) larvae may alter the performance of sanitary brood care in the clonal ant, Platythyrea punctata. We trained ants individually over nine consecutive trials to either sham-treated or fungus-exposed larvae. We then compared the larval grooming behavior of naive and trained ants and measured how effectively they removed infectious fungal conidiospores from the fungus-exposed larvae. We found that the ants changed the duration of larval grooming in response to both, larval treatment and their level of experience: (1) sham-treated larvae received longer grooming than the fungus-exposed larvae and (2) trained ants performed less self-grooming but longer larval grooming than naive ants, which was true for both, ants trained to fungus-exposed and also to sham-treated larvae. Ants that groomed the fungus-exposed larvae for longer periods removed a higher number of fungal conidiospores from the surface of the fungus-exposed larvae. As experienced ants performed longer larval grooming, they were more effective in fungal removal, thus making them better caretakers under pathogen attack of the colony. By studying this clonal ant, we can thus conclude that even in the absence of genetic variation between colony members, differences in experience levels of brood care may affect performance of sanitary brood care in social insects.","lang":"eng"}],"type":"research_data_reference","date_published":"2015-07-09T00:00:00Z","doi":"10.5061/dryad.7kc79","oa":1,"main_file_link":[{"open_access":"1","url":"https://doi.org/10.5061/dryad.7kc79"}],"citation":{"chicago":"Westhus, Claudia, Line V Ugelvig, Edouard Tourdot, Jürgen Heinze, Claudie Doums, and Sylvia Cremer. “Data from: Increased Grooming after Repeated Brood Care Provides Sanitary Benefits in a Clonal Ant.” Dryad, 2015. https://doi.org/10.5061/dryad.7kc79.","mla":"Westhus, Claudia, et al.

Pathogens of social insects need to adapt towards disease defences at two levels: 1) individual immunity of each colony member consisting of behavioural defence strategies as well as humoral and cellular immune responses and 2) social immunity that is collectively performed by all group members comprising behavioural, physiological and organisational defence strategies.\r\n\r\nTo disentangle the selection pressure on pathogens by the collective versus individual level of disease defence in social insects, we performed an evolution experiment using the Argentine Ant, Linepithema humile, as a host and a mixture of the general insect pathogenic fungus Metarhizium spp. (6 strains) as a pathogen. We allowed pathogen evolution over 10 serial host passages to two different evolution host treatments: (1) only individual host immunity in a single host treatment, and (2) simultaneously acting individual and social immunity in a social host treatment, in which an exposed ant was accompanied by two untreated nestmates.\r\n\r\nBefore starting the pathogen evolution experiment, the 6 Metarhizium spp. strains were characterised concerning conidiospore size killing rates in singly and socially reared ants, their competitiveness under coinfecting conditions and their influence on ant behaviour. We analysed how the ancestral atrain mixture changed in conidiospere size, killing rate and strain composition dependent on host treatment (single or social hosts) during 10 passages and found that killing rate and conidiospere size of the pathogen increased under both evolution regimes, but different depending on host treatment.\r\n\r\nTesting the evolved strain mixtures that evolved under either the single or social host treatment under both single and social current rearing conditions in a full factorial design experiment revealed that the additional collective defences in insect societies add new selection pressure for their coevolving pathogens that compromise their ability to adapt to its host at the group level. To our knowledge, this is the first study directly measuring the influence of social immunity on pathogen evolution.","lang":"eng"}],"publist_id":"5803","citation":{"ama":"Stock M.

We examined MHC variation in populations of the livebearing fish Poecilia mexicana and characterized their parasite communities. Poecilia mexicana populations in the Cueva del Azufre system are locally adapted to darkness and the presence of toxic hydrogen sulphide, representing highly divergent ecotypes or incipient species. Parasite communities differed significantly across populations, and populations with higher parasite loads had higher levels of diversity at class II MHC genes. However, despite different parasite communities, marked divergence in adaptive traits and in neutral genetic markers, we found MHC alleles to be remarkably similar among host populations. Our findings indicate that balancing selection from parasites maintains immunogenetic diversity of hosts, but this process does not promote MHC divergence in this system. On the contrary, we suggest that balancing selection on immunogenetic loci may outweigh divergent selection causing divergence, thereby hindering host divergence and speciation. Our findings support the hypothesis that balancing selection maintains MHC similarities among lineages during and after speciation (trans-species evolution)."}],"issue":"5","publication":"Journal of Evolutionary Biology","citation":{"mla":"Tobler, Michael, et al. “Selection from Parasites Favours Immunogenetic Diversity but Not Divergence among Locally Adapted Host Populations.” Journal of Evolutionary Biology, vol. 27, no. 5, Wiley, 2014, pp. 960–74, doi:10.1111/jeb.12370.","short":"M.

Honeybees (Apis mellifera), the prevailing managed insect crop pollinator, suffer from a range of emerging and exotic high-impact pathogens, and population maintenance requires active management by beekeepers to control them. Wild pollinators such as bumblebees (Bombus spp.) are in global decline, one cause of which may be pathogen spillover from managed pollinators like honeybees or commercial colonies of bumblebees. Here we use a combination of infection experiments and landscape-scale field data to show that honeybee EIDs are indeed widespread infectious agents within the pollinator assemblage. The prevalence of deformed wing virus (DWV) and the exotic parasite Nosema ceranae in honeybees and bumblebees is linked; as honeybees have higher DWV prevalence, and sympatric bumblebees and honeybees are infected by the same DWV strains, Apis is the likely source of at least one major EID in wild pollinators. Lessons learned from vertebrates highlight the need for increased pathogen control in managed bee species to maintain wild pollinators, as declines in native pollinators may be caused by interspecies pathogen transmission originating from managed pollinators.","lang":"eng"}],"intvolume":" 506","status":"public","title":"Disease associations between honeybees and bumblebees as a threat to wild pollinators","user_id":"4435EBFC-F248-11E8-B48F-1D18A9856A87","_id":"2235","oa_version":"Submitted Version","scopus_import":1,"day":"20","page":"364 - 366","citation":{"ama":"Fürst M, Mcmahon D, Osborne J, Paxton R, Brown M.

Likewise, host behavioural changes can be a defence mechanism, counteracting the impact of pathogens on host fitness. We apply harmonic radar technology to characterize the impact of an emerging pathogen - Nosema ceranae (Microsporidia) - on honeybee (Apis mellifera) flight and orientation performance in the field. Honeybees are the most important commercial pollinators. Emerging diseases have been proposed to play a prominent role in colony decline, partly through sub-lethal behavioural manipulation of their hosts. We found that homing success was significantly reduced in diseased (65.8%) versus healthy foragers (92.5%). Although lost bees had significantly reduced continuous flight times and prolonged resting times, other flight characteristics and navigational abilities showed no significant difference between infected and non-infected bees. Our results suggest that infected bees express normal flight characteristics but are constrained in their homing ability, potentially compromising the colony by reducing its resource inputs, but also counteracting the intra-colony spread of infection. We provide the first high-resolution analysis of sub-lethal effects of an emerging disease on insect flight behaviour.

We trained ants individually over nine consecutive trials to either sham-treated or fungus-exposed larvae. We then compared the larval grooming behavior of naive and trained ants and measured how effectively they removed infectious fungal conidiospores from the fungus-exposed larvae. We found that the ants changed the duration of larval grooming in response to both, larval treatment and their level of experience: (1) sham-treated larvae received longer grooming than the fungus-exposed larvae and (2) trained ants performed less self-grooming but longer larval grooming than naive ants, which was true for both, ants trained to fungus-exposed and also to sham-treated larvae. Ants that groomed the fungus-exposed larvae for longer periods removed a higher number of fungal conidiospores from the surface of the fungus-exposed larvae. As experienced ants performed longer larval grooming, they were more effective in fungal removal, thus making them better caretakers under pathogen attack of the colony. By studying this clonal ant, we can thus conclude that even in the absence of genetic variation between colony members, differences in experience levels of brood care may affect performance of sanitary brood care in social insects."}],"issue":"10","publication":"Behavioral Ecology and Sociobiology","citation":{"ama":"Westhus C, Ugelvig LV, Tourdot E, Heinze J, Doums C, Cremer S.

Here, we studied the novel association between the invasive garden ant Lasius neglectus and its fungal ectosymbiont Laboulbenia formicarum for potential costs and benefits. We tested ants with different Laboulbenia levels for their survival and immunity under resource limitation and exposure to the obligate killing entomopathogen Metarhizium brunneum. While survival of L. neglectus workers under starvation was significantly decreased with increasing Laboulbenia levels, host survival under Metarhizium exposure increased with higher levels of the ectosymbiont, suggesting a symbiont-mediated anti-pathogen protection, which seems to be driven mechanistically by both improved sanitary behaviours and an upregulated immune system. Ants with high Laboulbenia levels showed significantly longer self-grooming and elevated expression of immune genes relevant for wound repair and antifungal responses (β-1,3-glucan binding protein, Prophenoloxidase), compared with ants carrying low Laboulbenia levels. This suggests that the ectosymbiont Laboulbenia formicarum weakens its ant host by either direct resource exploitation or the costs of an upregulated behavioural and immunological response, which, however, provides a prophylactic protection upon later exposure to pathogens.","lang":"eng"}]},{"article_processing_charge":"No","month":"10","day":"08","citation":{"ama":"Tragust S, Ugelvig LV, Chapuisat M, Heinze J, Cremer S.

We here test whether the presence of a pupal cocoon, which occurs in some ant species but not in others, affects the sanitary brood care and fungal infection patterns after exposure to the entomopathogenic fungus Metarhizium brunneum. We use a) a comparative approach analysing four species with either naked or cocooned pupae and b) a within-species analysis of a single ant species, in which both pupal types co-exist in the same colony. Results: We found that the presence of a cocoon did not compromise fungal pathogen detection by the ants and that species with cocooned pupae increased brood grooming after pathogen exposure. All tested ant species further removed brood from their nests, which was predominantly expressed towards larvae and naked pupae treated with the live fungal pathogen. In contrast, cocooned pupae exposed to live fungus were not removed at higher rates than cocooned pupae exposed to dead fungus or a sham control. Consistent with this, exposure to the live fungus caused high numbers of infections and fungal outgrowth in larvae and naked pupae, but not in cocooned pupae. Moreover, the ants consistently removed the brood prior to fungal outgrowth, ensuring a clean brood chamber. Conclusion: Our study suggests that the pupal cocoon has a protective effect against fungal infection, causing an adaptive change in sanitary behaviours by the ants. It further demonstrates that brood removal - originally described for honeybees as “hygienic behaviour” – is a widespread sanitary behaviour in ants, which likely has important implications on disease dynamics in social insect colonies.","lang":"eng"}],"year":"2014","_id":"9753","user_id":"6785fbc1-c503-11eb-8a32-93094b40e1cf","department":[{"_id":"SyCr"}],"publisher":"Dryad","title":"Data from: Pupal cocoons affect sanitary brood care and limit fungal infections in ant colonies","status":"public","related_material":{"record":[{"id":"2284","status":"public","relation":"used_in_publication"}]},"author":[{"full_name":"Tragust, Simon","id":"35A7A418-F248-11E8-B48F-1D18A9856A87","first_name":"Simon","last_name":"Tragust"},{"full_name":"Ugelvig, Line V","orcid":"0000-0003-1832-8883","id":"3DC97C8E-F248-11E8-B48F-1D18A9856A87","last_name":"Ugelvig","first_name":"Line V"},{"first_name":"Michel","last_name":"Chapuisat","full_name":"Chapuisat, Michel"},{"full_name":"Heinze, Jürgen","first_name":"Jürgen","last_name":"Heinze"},{"full_name":"Cremer, Sylvia","last_name":"Cremer","first_name":"Sylvia","orcid":"0000-0002-2193-3868","id":"2F64EC8C-F248-11E8-B48F-1D18A9856A87"}],"oa_version":"Published Version","date_created":"2021-07-30T08:24:11Z","date_updated":"2023-02-23T10:36:17Z"},{"_id":"1395","year":"2014","user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","publication_status":"published","title":"Immune defences in ants: Effects of social immunisation and a fungal ectosymbiont in the ant Lasius neglectus","status":"public","publisher":"Institute of Science and Technology Austria","department":[{"_id":"SyCr"}],"author":[{"id":"46528076-F248-11E8-B48F-1D18A9856A87","first_name":"Matthias","last_name":"Konrad","full_name":"Konrad, Matthias"}],"date_created":"2018-12-11T11:51:46Z","date_updated":"2023-09-07T11:38:56Z","oa_version":"None","type":"dissertation","alternative_title":["ISTA Thesis"],"abstract":[{"text":"In this thesis I studied various individual and social immune defences employed by the invasive garden ant Lasius neglectus mostly against entomopathogenic fungi. The first two chapters of this thesis address the phenomenon of 'social immunisation'. Social immunisation, that is the immunological protection of group members due to social contact to a pathogen-exposed nestmate, has been described in various social insect species against different types of pathogens. However, in the case of entomopathogenic fungi it has, so far, only been demonstrated that social immunisation exists at all. Its underlying mechanisms r any other properties were, however, unknown. In the first chapter of this thesis I identified the mechanistic basis of social immunisation in L. neglectus against the entomopathogenous fungus Metarhizium. I could show that nestmates of a pathogen-exposed individual contract low-level infections due to social interactions. These low-level infections are, however, non-lethal and cause an active stimulation of the immune system, which protects the nestmates upon subsequent pathogen encounters. In the second chapter of this thesis I investigated the specificity and colony level effects of social immunisation. I demonstrated that the protection conferred by social immunisation is highly specific, protecting ants only against the same pathogen strain. In addition, depending on the respective context, social immunisation may even cause fitness costs. I further showed that social immunisation crucially affects sanitary behaviour and disease dynamics within ant groups. In the third chapter of this thesis I studied the effects of the ectosymbiotic fungus Laboulbenia formicarum on its host L. neglectus. Although Laboulbeniales are the largest order of insect-parasitic fungi, research concerning host fitness consequence is sparse. I showed that highly Laboulbenia-infected ants sustain fitness costs under resource limitation, however, gain fitness benefits when exposed to an entomopathogenus fungus. These effects are probably cause by a prophylactic upregulation of behavioural as well as physiological immune defences in highly infected ants.","lang":"eng"}],"publist_id":"5814","citation":{"short":"M.

In addition to individual immunity, social organisms can act cooperatively to produce collective defences. In many ant species, queens have the option to found a colony alone or in groups with other, often unrelated, conspecifics. These associations are transient, usually lasting only as long as each queen benefits from the presence of others. In fact, once the first workers emerge, queens fight to the death for dominance. One potential advantage of co-founding may be that queens benefit from collective disease defences, such as mutual grooming, that act against common soil pathogens. We test this hypothesis by exposing single and co-founding queens to a fungal parasite, in order to assess whether queens in co-founding associations have improved survival. Surprisingly, co-foundresses exposed to the entomopathogenic fungus Metarhizium did not engage in cooperative disease defences, and consequently, we find no direct benefit of multiple queens on survival. However, an indirect benefit was observed, with parasite-exposed queens producing more brood when they co-founded, than when they were alone. We suggest this is due to a trade-off between reproduction and immunity. Additionally, we report an extraordinary ability of the queens to tolerate an infection for long periods after parasite exposure. Our study suggests that there are no social immunity benefits for co-founding ant queens, but that in parasite-rich environments, the presence of additional queens may nevertheless improve the chances of colony founding success.","lang":"eng"}],"issue":"12","publist_id":"4649","type":"journal_article","doi":"10.1007/s00114-013-1115-5","date_published":"2013-11-14T00:00:00Z","language":[{"iso":"eng"}],"publication":"Naturwissenschaften","citation":{"chicago":"Pull, Christopher, William Hughes, and Markus Brown. “Tolerating an Infection: An Indirect Benefit of Co-Founding Queen Associations in the Ant Lasius Niger .” Naturwissenschaften.

We here test whether the presence of a pupal cocoon, which occurs in some ant species but not in others, affects the sanitary brood care and fungal infection patterns after exposure to the entomopathogenic fungus Metarhizium brunneum. We use a) a comparative approach analysing four species with either naked or cocooned pupae and b) a within-species analysis of a single ant species, in which both pupal types co-exist in the same colony. Results: We found that the presence of a cocoon did not compromise fungal pathogen detection by the ants and that species with cocooned pupae increased brood grooming after pathogen exposure. All tested ant species further removed brood from their nests, which was predominantly expressed towards larvae and naked pupae treated with the live fungal pathogen. In contrast, cocooned pupae exposed to live fungus were not removed at higher rates than cocooned pupae exposed to dead fungus or a sham control. Consistent with this, exposure to the live fungus caused high numbers of infections and fungal outgrowth in larvae and naked pupae, but not in cocooned pupae. Moreover, the ants consistently removed the brood prior to fungal outgrowth, ensuring a clean brood chamber. Conclusion: Our study suggests that the pupal cocoon has a protective effect against fungal infection, causing an adaptive change in sanitary behaviours by the ants. It further demonstrates that brood removal-originally described for honeybees as "hygienic behaviour"-is a widespread sanitary behaviour in ants, which likely has important implications on disease dynamics in social insect colonies.","lang":"eng"}],"_id":"2284","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","intvolume":" 13","ddc":["570"],"title":"Pupal cocoons affect sanitary brood care and limit fungal infections in ant colonies","status":"public","pubrep_id":"402","oa_version":"Published Version","file":[{"content_type":"application/pdf","file_size":281736,"creator":"system","access_level":"open_access","file_name":"IST-2016-402-v1+1_1471-2148-13-225.pdf","checksum":"c16ef36f2a10786a7885e19c4528d707","date_updated":"2020-07-14T12:45:37Z","date_created":"2018-12-12T10:13:41Z","relation":"main_file","file_id":"5026"}],"scopus_import":1,"has_accepted_license":"1","day":"14","citation":{"ista":"Tragust S, Ugelvig LV, Chapuisat M, Heinze J, Cremer S. 2013.

Sanitary behavior, such as pathogen avoidance and removal, acts as a first line of defense to prevent infection [1] before activation of the physiological immune system. Insect societies have evolved a wide range of collective hygiene measures and intensive health care toward pathogen-exposed group members [2]. One of the most common behaviors is allogrooming, in which nestmates remove infectious particles from the body surfaces of exposed individuals [3]. Here we show that, in invasive garden ants, grooming of fungus-exposed brood is effective beyond the sheer mechanical removal of fungal conidiospores; it also includes chemical disinfection through the application of poison produced by the ants themselves. Formic acid is the main active component of the poison. It inhibits fungal growth of conidiospores remaining on the brood surface after grooming and also those collected in the mouth of the grooming ant. This dual function is achieved by uptake of the poison droplet into the mouth through acidopore self-grooming and subsequent application onto the infectious brood via brood grooming. This extraordinary behavior extends the current understanding of grooming and the establishment of social immunity in insect societies."}],"issue":"1","type":"journal_article","oa_version":"None","title":"Ants disinfect fungus-exposed brood by oral uptake and spread of their poison","status":"public","intvolume":" 23","_id":"2926","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87"},{"page":"1300 - 1312","quality_controlled":"1","citation":{"ama":"Ugelvig LV, Cremer S.

Similar to solitary species, parasite release followed by the evolution of increased competitive ability can promote establishment of introduced social insect hosts in their introduced range. Genetic bottlenecks during introduction of low numbers of founder individuals decrease the genetic diversity at three levels: the population, the colony and the individual, with the colony level being specific to social insects. Reduced genetic diversity can affect both the individual immune system and the collective colony-level disease defences (social immunity). Still, the dual immune system is likely to make social insects more robust to parasite attack. Changes in social structure from small, family-based, territorially aggressive societies in native populations towards huge networks of cooperating nests (unicoloniality) occur in some invasive social insects, for example, most invasive ants and some termites. Unicoloniality is likely to affect disease dynamics in multiple ways. The free exchange of individuals within the population leads to an increased genetic heterogeneity among individuals of a single nest, thereby decreasing disease transmission. However, the multitude of reproductively active queens per colony buffers the effect of individual diseased queens and their offspring, which may result in a higher level of vertical disease transmission in unicolonial societies. Lastly, unicoloniality provides a competitive advantage over native species, allowing them to quickly become the dominant species in the habitat, which in turn selects for parasite adaptation to this common host genotype and thus eventually a high parasite pressure. Overall, invasions by insect societies are characterized by general features applying to all introduced species, as well as idiosyncrasies that emerge from their social lifestyle. It is important to study these effects in concert to be able to develop efficient management and biocontrol strategies. © 2012 British Ecological Society.","lang":"eng"}]},{"month":"06","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"oa":1,"quality_controlled":"1","doi":"10.1186/1472-6785-12-7","language":[{"iso":"eng"}],"article_number":"7","publist_id":"3753","file_date_updated":"2020-07-14T12:45:57Z","year":"2012","publisher":"BioMed Central","department":[{"_id":"SyCr"}],"publication_status":"published","author":[{"full_name":"Cremer, Sylvia","last_name":"Cremer","first_name":"Sylvia","orcid":"0000-0002-2193-3868","id":"2F64EC8C-F248-11E8-B48F-1D18A9856A87"},{"last_name":"Suefuji","first_name":"Masaki","full_name":"Suefuji, Masaki"},{"full_name":"Schrempf, Alexandra","first_name":"Alexandra","last_name":"Schrempf"},{"last_name":"Heinze","first_name":"Jürgen","full_name":"Heinze, Jürgen"}],"volume":12,"date_created":"2018-12-11T12:00:35Z","date_updated":"2021-01-12T07:40:07Z","scopus_import":1,"has_accepted_license":"1","day":"15","citation":{"short":"S.

In insects, freshly emerged and still sexually inactive males are morphologically indistinct from older, sexually active males. These young inactive males may thus be easy targets for older males if they cannot conceal themselves from their attacks. The ant Cardiocondyla obscurior is characterised by lethal fighting between wingless (" ergatoid" ) males. Here, we analyse for how long young males are defenceless after eclosion, and how early adult males can detect the presence of rival males.Results: We found that old ergatoid males consistently won fights against ergatoid males younger than two days. Old males did not differentiate between different types of unpigmented pupae several days before emergence, but had more frequent contact to ready-to-eclose pupae of female sexuals and winged males than of workers and ergatoid males. In rare cases, old ergatoid males displayed alleviated biting of pigmented ergatoid male pupae shortly before adult eclosion, as well as copulation attempts to dark pupae of female sexuals and winged males. Ergatoid male behaviour may be promoted by a closer similarity of the chemical profile of ready-to-eclose pupae to the profile of adults than that of young pupae several days prior to emergence.Conclusion: Young ergatoid males of C. obscurior would benefit greatly by hiding their identity from older, resident males, as they are highly vulnerable during the first two days of their adult lives. In contrast to the winged males of the same species, which are able to prevent ergatoid male attacks by chemical female mimicry, young ergatoids do not seem to be able to produce a protective chemical profile. Conflicts in male-male competition between ergatoid males of different age thus seem to be resolved in favour of the older males. This might represent selection at the colony level rather than the individual level. © 2012 Cremer et al.; licensee BioMed Central Ltd.","lang":"eng"}],"user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"2966","intvolume":" 12","title":"The dynamics of male-male competition in Cardiocondyla obscurior ants","ddc":["570"],"status":"public","pubrep_id":"94","oa_version":"Published Version","file":[{"file_id":"4706","relation":"main_file","checksum":"03d004bdff3724fb1627e3f5004bad80","date_updated":"2020-07-14T12:45:57Z","date_created":"2018-12-12T10:08:44Z","access_level":"open_access","file_name":"IST-2012-94-v1+1_1472-6785-12-7.pdf","creator":"system","file_size":489994,"content_type":"application/pdf"}]},{"_id":"3132","year":"2012","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","acknowledgement":"We like to thank the editor and three anonymous reviewers for their time and constructive criticism and Inon Scharf, Volker Witte and Andreas Modlmeier for helpful comments on earlier versions of the manuscript.

The dominant reproductive individual, often the queen, uses chemical communication and/or behaviour to maintain her social status. Queens of many social insects communicate their fertility status via cuticle-bound substances. As these substances usually possess a low volatility, their range in queen–worker communication is potentially limited. Here, we investigate the range and impact of behavioural and chemical queen signals on workers of the ant Temnothorax longispinosus. We compared the behaviour and ovary development of workers subjected to three different treatments: workers with direct chemical and physical contact to the queen, those solely under the influence of volatile queen substances and those entirely separated from the queen. In addition to short-ranged queen signals preventing ovary development in workers, we discovered a novel secondary pathway influencing worker behaviour. Workers with no physical contact to the queen, but exposed to volatile substances, started to develop their ovaries, but did not change their behaviour compared to workers in direct contact to the queen. In contrast, workers in queen-separated groups showed both increased ovary development and aggressive dominance interactions. We conclude that T. longispinosus queens influence worker ovary development and behaviour via two independent signals, both ensuring social harmony within the colony.","lang":"eng"}],"citation":{"short":"M.

Loss of cellular potassium is known to potently suppress protein synthesis, leading us to test whether the inhibition of protein synthesis itself serves as an activating signal for the NLRP3 inflammasome. Murine bone marrow-derived macrophages, either primed by LPS or unprimed, were exposed to a panel of inhibitors of ribosomal function: ricin, cycloheximide, puromycin, pactamycin, and anisomycin. Macrophages were also exposed to nigericin, ATP, monosodium urate (MSU), and poly I:C. Synthesis of pro-IL-ß and release of IL-1ß from cells in response to these agents was detected by immunoblotting and ELISA. Release of intracellular potassium was measured by mass spectrometry. Inhibition of translation by each of the tested translation inhibitors led to processing of IL-1ß, which was released from cells. Processing and release of IL-1ß was reduced or absent from cells deficient in NLRP3, ASC, or caspase-1, demonstrating the role of the NLRP3 inflammasome. Despite the inability of these inhibitors to trigger efflux of intracellular potassium, the addition of high extracellular potassium suppressed activation of the NLRP3 inflammasome. MSU and double-stranded RNA, which are known to activate the NLRP3 inflammasome, also substantially inhibited protein translation, supporting a close association between inhibition of translation and inflammasome activation. These data demonstrate that translational inhibition itself constitutes a heretofore-unrecognized mechanism underlying IL-1ß dependent inflammatory signaling and that other physical, chemical, or pathogen-associated agents that impair translation may lead to IL-1ß-dependent inflammation through activation of the NLRP3 inflammasome. For agents that inhibit translation through decreased cellular potassium, the application of high extracellular potassium restores protein translation and suppresses activation of the NLRP inflammasome. For agents that inhibit translation through mechanisms that do not involve loss of potassium, high extracellular potassium suppresses IL-1ß processing through a mechanism that remains undefined.","lang":"eng"}],"type":"journal_article"},{"day":"01","month":"07","scopus_import":1,"date_published":"2012-07-01T00:00:00Z","doi":"10.1111/j.1365-294X.2012.05592.x","language":[{"iso":"eng"}],"citation":{"chicago":"Ugelvig, Line V, Anne Andersen, Jacobus Boomsma, and David Nash. “Dispersal and Gene Flow in the Rare Parasitic Large Blue Butterfly Maculinea Arion.” Molecular Ecology.

Such species are often foci of conservation efforts because they suffer disproportionally from degradation and fragmentation of their habitat. However, detailed knowledge of effective gene flow through dispersal is often missing, so that conservation strategies have to be based on mark-recapture observations that are suspected to be poor predictors of long-distance dispersal. These constraints have been especially severe in the study of butterfly populations, where microsatellite markers have been difficult to develop. We used eight microsatellite markers to analyse genetic population structure of the Large Blue butterfly Maculinea arion in Sweden. During recent decades, this species has become an icon of insect conservation after massive decline throughout Europe and extinction in Britain followed by reintroduction of a seed population from the Swedish island of Öland. We find that populations are highly structured genetically, but that gene flow occurs over distances 15 times longer than the maximum distance recorded from mark-recapture studies, which can only be explained by maximum dispersal distances at least twice as large as previously accepted. However, we also find evidence that gaps between sites with suitable habitat exceeding ∼ 20 km induce genetic erosion that can be detected from bottleneck analyses. Although further work is needed, our results suggest that M. arion can maintain fully functional metapopulations when they consist of optimal habitat patches that are no further apart than ∼10 km.","lang":"eng"}],"type":"journal_article","author":[{"last_name":"Ugelvig","first_name":"Line V","orcid":"0000-0003-1832-8883","id":"3DC97C8E-F248-11E8-B48F-1D18A9856A87","full_name":"Ugelvig, Line V"},{"full_name":"Andersen, Anne","first_name":"Anne","last_name":"Andersen"},{"first_name":"Jacobus","last_name":"Boomsma","full_name":"Boomsma, Jacobus"},{"first_name":"David","last_name":"Nash","full_name":"Nash, David"}],"volume":21,"oa_version":"None","date_updated":"2021-01-12T07:41:27Z","date_created":"2018-12-11T12:01:43Z","_id":"3156","acknowledgement":"The work was financed by the Danish National Science Research Foundation via a grant to the Centre for Social Evolution.\r\nWe thank four anonymous reviewers for useful comments on the manuscript, J.

An intriguing yet little understood phenomenon is that social contact to pathogen-exposed individuals reduces susceptibility of previously naive nestmates to this pathogen. We tested whether such social immunisation in Lasius ants against the entomopathogenic fungus Metarhizium anisopliae is based on active upregulation of the immune system of nestmates following contact to an infectious individual or passive protection via transfer of immune effectors among group members—that is, active versus passive immunisation. We found no evidence for involvement of passive immunisation via transfer of antimicrobials among colony members. Instead, intensive allogrooming behaviour between naive and pathogen-exposed ants before fungal conidia firmly attached to their cuticle suggested passage of the pathogen from the exposed individuals to their nestmates. By tracing fluorescence-labelled conidia we indeed detected frequent pathogen transfer to the nestmates, where they caused low-level infections as revealed by growth of small numbers of fungal colony forming units from their dissected body content. These infections rarely led to death, but instead promoted an enhanced ability to inhibit fungal growth and an active upregulation of immune genes involved in antifungal defences (defensin and prophenoloxidase, PPO). Contrarily, there was no upregulation of the gene cathepsin L, which is associated with antibacterial and antiviral defences, and we found no increased antibacterial activity of nestmates of fungus-exposed ants. This indicates that social immunisation after fungal exposure is specific, similar to recent findings for individual-level immune priming in invertebrates. Epidemiological modeling further suggests that active social immunisation is adaptive, as it leads to faster elimination of the disease and lower death rates than passive immunisation. Interestingly, humans have also utilised the protective effect of low-level infections to fight smallpox by intentional transfer of low pathogen doses (“variolation” or “inoculation”).","lang":"eng"}],"type":"journal_article","file":[{"file_id":"4689","relation":"main_file","date_created":"2018-12-12T10:08:28Z","date_updated":"2020-07-14T12:46:04Z","checksum":"4ebacefd9fbab5c68adf829124115fd1","file_name":"IST-2012-96-v1+1_journal.pbio.1001300.pdf","access_level":"open_access","creator":"system","content_type":"application/pdf","file_size":674228}],"oa_version":"Published Version","pubrep_id":"96","intvolume":" 10","ddc":["570","579"],"status":"public","title":"Social transfer of pathogenic fungus promotes active immunisation in ant colonies","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","_id":"3242","has_accepted_license":"1","day":"03","scopus_import":1,"date_published":"2012-04-03T00:00:00Z","citation":{"ama":"Konrad M, Vyleta M, Theis F, et al.

An intriguing yet little understood phenomenon is that social contact to pathogen-exposed individuals reduces susceptibility of previously naive nestmates to this pathogen. We tested whether such social immunisation in Lasius ants against the entomopathogenic fungus Metarhizium anisopliae is based on active upregulation of the immune system of nestmates following contact to an infectious individual or passive protection via transfer of immune effectors among group members—that is, active versus passive immunisation. We found no evidence for involvement of passive immunisation via transfer of antimicrobials among colony members. Instead, intensive allogrooming behaviour between naive and pathogen-exposed ants before fungal conidia firmly attached to their cuticle suggested passage of the pathogen from the exposed individuals to their nestmates. By tracing fluorescence-labelled conidia we indeed detected frequent pathogen transfer to the nestmates, where they caused low-level infections as revealed by growth of small numbers of fungal colony forming units from their dissected body content. These infections rarely led to death, but instead promoted an enhanced ability to inhibit fungal growth and an active upregulation of immune genes involved in antifungal defences (defensin and prophenoloxidase, PPO). Contrarily, there was no upregulation of the gene cathepsin L, which is associated with antibacterial and antiviral defences, and we found no increased antibacterial activity of nestmates of fungus-exposed ants. This indicates that social immunisation after fungal exposure is specific, similar to recent findings for individual-level immune priming in invertebrates. Epidemiological modeling further suggests that active social immunisation is adaptive, as it leads to faster elimination of the disease and lower death rates than passive immunisation. Interestingly, humans have also utilised the protective effect of low-level infections to fight smallpox by intentional transfer of low pathogen doses (“variolation” or “inoculation”)."}],"type":"research_data_reference","date_updated":"2023-02-23T11:18:41Z","date_created":"2021-07-30T08:39:13Z","oa_version":"Published Version","author":[{"id":"46528076-F248-11E8-B48F-1D18A9856A87","first_name":"Matthias","last_name":"Konrad","full_name":"Konrad, Matthias"},{"id":"418901AA-F248-11E8-B48F-1D18A9856A87","first_name":"Meghan","last_name":"Vyleta","full_name":"Vyleta, Meghan"},{"last_name":"Theis","first_name":"Fabian","full_name":"Theis, Fabian"},{"id":"42462816-F248-11E8-B48F-1D18A9856A87","first_name":"Miriam","last_name":"Stock","full_name":"Stock, Miriam"},{"id":"E60F29C6-E9AE-11E9-AF6E-D190C7302F38","last_name":"Klatt","first_name":"Martina","full_name":"Klatt, Martina"},{"full_name":"Drescher, Verena","first_name":"Verena","last_name":"Drescher"},{"first_name":"Carsten","last_name":"Marr","full_name":"Marr, Carsten"},{"full_name":"Ugelvig, Line V","last_name":"Ugelvig","first_name":"Line V","orcid":"0000-0003-1832-8883","id":"3DC97C8E-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Cremer, Sylvia","id":"2F64EC8C-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2193-3868","first_name":"Sylvia","last_name":"Cremer"}],"related_material":{"record":[{"id":"3242","status":"public","relation":"used_in_publication"}]},"title":"Data from: Social transfer of pathogenic fungus promotes active immunisation in ant colonies","status":"public","publisher":"Dryad","department":[{"_id":"SyCr"}],"_id":"9755","user_id":"6785fbc1-c503-11eb-8a32-93094b40e1cf","year":"2012"},{"oa":1,"citation":{"chicago":"Tragust, Simon, Barbara Mitteregger, Vanessa Barone, Matthias Konrad, Line V Ugelvig, and Sylvia Cremer. “Data from: Ants Disinfect Fungus-Exposed Brood by Oral Uptake and Spread of Their Poison.” Dryad, 2012. https://doi.org/10.5061/dryad.61649.","short":"S.

Sanitary behaviour, such as pathogen avoidance and removal, acts as a first line of defence to prevent infection [1] before activation of the physiological immune system. Insect societies have evolved a wide range of collective hygiene measures and intensive health care towards pathogen-exposed group members [2]. One of the most common behaviours is allogrooming, in which nestmates remove infectious particles from the body surfaces of exposed individuals [3]. Here we show that, in invasive garden ants, grooming of fungus-exposed brood is effective beyond the sheer mechanical removal of fungal conidiospores as it also includes chemical disinfection through the application of poison produced by the ants themselves. Formic acid is the main active component of the poison. It inhibits fungal growth of conidiospores remaining on the brood surface after grooming and also those collected in the mouth of the grooming ant. This dual function is achieved by uptake of the poison droplet into the mouth through acidopore self-grooming and subsequent application onto the infectious brood via brood grooming. This extraordinary behaviour extends current understanding of grooming and the establishment of social immunity in insect societies.","lang":"eng"}]},{"month":"07","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"oa":1,"quality_controlled":"1","doi":"10.1186/1471-2148-11-201","language":[{"iso":"eng"}],"article_number":"201","file_date_updated":"2020-07-14T12:46:11Z","publist_id":"3220","year":"2011","publication_status":"published","department":[{"_id":"SyCr"}],"publisher":"BioMed Central","author":[{"orcid":"0000-0003-1832-8883","id":"3DC97C8E-F248-11E8-B48F-1D18A9856A87","last_name":"Ugelvig","first_name":"Line V","full_name":"Ugelvig, Line V"},{"last_name":"Nielsen","first_name":"Per","full_name":"Nielsen, Per"},{"last_name":"Boomsma","first_name":"Jacobus","full_name":"Boomsma, Jacobus"},{"full_name":"Nash, David","last_name":"Nash","first_name":"David"}],"date_created":"2018-12-11T12:03:03Z","date_updated":"2021-01-12T07:43:08Z","volume":11,"scopus_import":1,"day":"11","has_accepted_license":"1","publication":"BMC Evolutionary Biology","citation":{"ama":"Ugelvig LV, Nielsen P, Boomsma J, Nash D.

Maculinea butterflies have been particularly affected because of their specialized lifecycles, requiring both specific food-plants and host-ants. However, the interaction between dispersal, effective population size, and long-term genetic erosion of these endangered butterflies remains unknown. Using non-destructive sampling, we investigated the genetic diversity of the last extant population of M. arion in Denmark, which experienced critically low numbers in the 1980s. Results: Using nine microsatellite markers, we show that the population is genetically impoverished compared to nearby populations in Sweden, but less so than monitoring programs suggested. Ten additional short repeat microsatellites were used to reconstruct changes in genetic diversity and population structure over the last 77 years from museum specimens. We also tested amplification efficiency in such historical samples as a function of repeat length and sample age. Low population numbers in the 1980s did not affect genetic diversity, but considerable turnover of alleles has characterized this population throughout the time-span of our analysis. Conclusions: Our results suggest that M. arion is less sensitive to genetic erosion via population bottlenecks than previously thought, and that managing clusters of high quality habitat may be key for long-term conservation.","lang":"eng"}],"issue":"201","user_id":"3E5EF7F0-F248-11E8-B48F-1D18A9856A87","_id":"3388","status":"public","title":"Reconstructing eight decades of genetic variation in an isolated Danish population of the large blue butterfly Maculinea arion","ddc":["576"],"intvolume":" 11","pubrep_id":"371","file":[{"access_level":"open_access","file_name":"IST-2015-371-v1+1_1471-2148-11-201.pdf","creator":"system","file_size":2166556,"content_type":"application/pdf","file_id":"5069","relation":"main_file","checksum":"9ebfed0740f1fa071d02ec32c2b8c17f","date_updated":"2020-07-14T12:46:11Z","date_created":"2018-12-12T10:14:18Z"}],"oa_version":"Published Version"},{"abstract":[{"text":"Evolutionary theories of ageing predict that life span increases with decreasing extrinsic mortality, and life span variation among queens in ant species seems to corroborate this prediction: queens, which are the only reproductive in a colony, live much longer than queens in multi-queen colonies. The latter often inhabit ephemeral nest sites and accordingly are assumed to experience a higher mortality risk. Yet, all prior studies compared queens from different single- and multi-queen species. Here, we demonstrate an effect of queen number on longevity and fecundity within a single, socially plastic species, where queens experience the similar level of extrinsic mortality. Queens from single- and two-queen colonies had significantly longer lifespan and higher fecundity than queens living in associations of eight queens. As queens also differ neither in morphology nor the mode of colony foundation, our study shows that the social environment itself strongly affects ageing rate.","lang":"eng"}],"publist_id":"3221","issue":"7","type":"journal_article","author":[{"last_name":"Schrempf","first_name":"Alexandra","full_name":"Schrempf, Alexandra"},{"full_name":"Cremer, Sylvia","orcid":"0000-0002-2193-3868","id":"2F64EC8C-F248-11E8-B48F-1D18A9856A87","last_name":"Cremer","first_name":"Sylvia"},{"first_name":"Jürgen","last_name":"Heinze","full_name":"Heinze, Jürgen"}],"date_created":"2018-12-11T12:03:02Z","date_updated":"2021-01-12T07:43:08Z","volume":24,"oa_version":"None","_id":"3386","user_id":"2DF688A6-F248-11E8-B48F-1D18A9856A87","year":"2011","title":"Social influence on age and reproduction reduced lifespan and fecundity in multi queen ant colonies","status":"public","publication_status":"published","publisher":"Wiley-Blackwell","intvolume":" 24","department":[{"_id":"SyCr"}],"month":"04","day":"21","scopus_import":1,"doi":"10.1111/j.1420-9101.2011.02278.x","date_published":"2011-04-21T00:00:00Z","language":[{"iso":"eng"}],"publication":"Journal of Evolutionary Biology","citation":{"mla":"Schrempf, Alexandra, et al. “Social Influence on Age and Reproduction Reduced Lifespan and Fecundity in Multi Queen Ant Colonies.” Journal of Evolutionary Biology, vol. 24, no. 7, Wiley-Blackwell, 2011, pp. 1455–61, doi:10.1111/j.1420-9101.2011.02278.x.","short":"A.

We used the ant Cardiocondyla obscurior as a model system to study adaptive adjustment of male mating tactics. This species shows a male diphenism of wingless fighter males and peaceful winged males. Whereas the wingless males stay and exclusively mate in the maternal colony, the mating behaviour of winged males is plastic. They copulate with female sexuals in their natal nests early in life but later disperse in search for sexuals outside. In this study, we observed the nest-leaving behaviour of winged males under different conditions and found that they adaptively adjust the timing of their dispersal to the availability of mating partners, as well as the presence, and even the type of competitors in their natal nests. In colonies with virgin female queens winged males stayed longest when they were the only male in the nest. They left earlier when mating partners were not available or when other males were present. In the presence of wingless, locally mating fighter males, winged males dispersed earlier than in the presence of docile, winged competitors. This suggests that C. obscurior males are capable of estimating their local breeding chances and adaptively adjust their dispersal behaviour in both an opportunistic and a risk-sensitive way, thus showing hitherto unknown behavioural plasticity in social insect males.","lang":"eng"}],"issue":"3","tmp":{"name":"Creative Commons Attribution 4.0 International Public License (CC-BY 4.0)","legal_code_url":"https://creativecommons.org/licenses/by/4.0/legalcode","short":"CC BY (4.0)","image":"/images/cc_by.png"},"oa":1,"quality_controlled":"1","doi":"10.1371/journal.pone.0017323","language":[{"iso":"eng"}],"month":"03","year":"2011","acknowledgement":"This work was supported by the German Science Foundation (www.dfg.de, He 1623/23).","publication_status":"published","publisher":"Public Library of Science","department":[{"_id":"SyCr"}],"author":[{"full_name":"Cremer, Sylvia","first_name":"Sylvia","last_name":"Cremer","id":"2F64EC8C-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0002-2193-3868"},{"last_name":"Schrempf","first_name":"Alexandra","full_name":"Schrempf, Alexandra"},{"last_name":"Heinze","first_name":"Jürgen","full_name":"Heinze, Jürgen"}],"date_updated":"2021-01-12T07:43:12Z","date_created":"2018-12-11T12:03:07Z","volume":6,"article_number":"e17323","file_date_updated":"2020-07-14T12:46:12Z","publist_id":"3059"}]
