Here, we report on a joint genetic and ecological analysis of a hybrid zone in the vicinity of Stryi in western Ukraine. We used five unlinked allozyme loci, two nuclear single nucleotide polymorphisms and a mitochondrial DNA haplotype as genetic markers. Parallel allele frequency clines with a sharp central step occur across a sharp ecotone, where transitions in aquatic habitat, elevation, and terrestrial vegetation coincide. The width of the hybrid zone, estimated as the inverse of the maximum gradient in allele frequency, is 2.3 km. This is the smallest of four estimates derived from different clinal transects across Europe. We argue that the narrow cline near Stryi is mainly due to a combination of habitat distribution and habitat preference. Adult toads show a preference for either ponds (B. bombina) or puddles (B. variegata), which is known to affect the distribution of genotypes within the hybrid zones. At Stryi, it should cause a reduction of the dispersal rate across the ecotone and thus narrow the cline. A detailed comparison of all five intensively studied Bombina transects lends support to the hypothesis that habitat distribution plus habitat preference can jointly affect the structure of hybrid zones and, ultimately, the resulting barriers to gene flow between differentiated gene pools. This study also represents a resampling of an area that was last studied more than 70 years ago. Our allele-frequency clines largely coincide with those that were described then on the basis of morphological variation. However, we found asymmetrical introgression of B. variegata genes into B. bombina territory along the bank of a river."}],"type":"journal_article","volume":60,"date_created":"2018-12-11T12:04:13Z","date_updated":"2021-01-12T07:44:38Z","author":[{"full_name":"Yanchukov, Alexey","first_name":"Alexey","last_name":"Yanchukov"},{"last_name":"Hofman","first_name":"Sebastian","full_name":"Hofman, Sebastian"},{"full_name":"Szymura, Jacek M","first_name":"Jacek","last_name":"Szymura"},{"first_name":"Sergey","last_name":"Mezhzherin","full_name":"Mezhzherin, Sergey V"},{"last_name":"Morozov Leonov","first_name":"Sviatoslav","full_name":"Morozov-Leonov, Sviatoslav"},{"full_name":"Nicholas Barton","last_name":"Barton","first_name":"Nicholas H","orcid":"0000-0002-8548-5240","id":"4880FE40-F248-11E8-B48F-1D18A9856A87"},{"full_name":"Nürnberger, Beate","last_name":"Nürnberger","first_name":"Beate"}],"publisher":"Wiley-Blackwell","intvolume":" 60","publication_status":"published","status":"public","title":"Hybridization of Bombina bombina and B. variegata (Anura, Discoglossidae) at a sharp ecotone in western Ukraine: comparisons across transects and over time","year":"2006","_id":"3609"},{"author":[{"full_name":"Kirkpatrick, Mark","last_name":"Kirkpatrick","first_name":"Mark"},{"full_name":"Nicholas Barton","last_name":"Barton","first_name":"Nicholas H","orcid":"0000-0002-8548-5240","id":"4880FE40-F248-11E8-B48F-1D18A9856A87"}],"date_created":"2018-12-11T12:04:13Z","date_updated":"2021-01-12T07:44:37Z","volume":173,"_id":"3608","year":"2006","title":"Chromosome inversions, local adaptation, and speciation","publication_status":"published","status":"public","publisher":"Genetics Society of America","intvolume":" 173","abstract":[{"lang":"eng","text":"We study the evolution of inversions that capture locally adapted alleles when two populations are exchanging migrants or hybridizing. By suppressing recombination between the loci, a new inversion can spread. Neither drift nor coadaptation between the alleles (epistasis) is needed, so this local adaptation mechanism may apply to a broader range of genetic and demographic situations than alternative hypotheses that have been widely discussed. The mechanism can explain many features observed in inversion systems. It will drive an inversion to high frequency if there is no countervailing force, which could explain fixed differences observed between populations and species. An inversion can be stabilized at an intermediate frequency if it also happens to capture one or more deleterious recessive mutations, which could explain polymorphisms that are common in some species. This polymorphism can cycle in frequency with the changing selective advantage of the locally favored alleles. The mechanism can establish underdominant inversions that decrease heterokaryotype fitness by several percent if the cause of fitness loss is structural, while if the cause is genic there is no limit to the strength of underdominance that can result. The mechanism is expected to cause loci responsible for adaptive species-specific differences to map to inversions, as seen in recent QTL studies. We discuss data that support the hypothesis, review other mechanisms for inversion evolution, and suggest possible tests.

Finite impulse response filters in the time domain with Gaussian masks are easy to implement in either floating or fixed point arithmetic, because Gaussian kernels are strictly positive and bounded. But these implementations are slow for large images or kernels. With the recursive IIR-filters and FFT-based methods, there are at least two alternative methods to perform Gaussian filtering in a faster way, but so far they are only applicable when floating-point hardware is available. In this paper, a fixed-point implementation of recursive Gaussian filtering is discussed and applied to isotropic and anisotropic image filtering by making use of a non-orthogonal separation scheme of the Gaussian filter.","lang":"eng"}],"publisher":"IEEE","publication_status":"published","title":"Anisotropic Gaussian filtering using fixed point arithmetic","status":"public","_id":"3693","year":"2006","date_updated":"2021-01-12T07:49:00Z","date_created":"2018-12-11T12:04:39Z","author":[{"first_name":"Christoph","last_name":"Lampert","id":"40C20FD2-F248-11E8-B48F-1D18A9856A87","orcid":"0000-0001-8622-7887","full_name":"Christoph Lampert"},{"full_name":"Wirjadi,Oliver","first_name":"Oliver","last_name":"Wirjadi"}]},{"citation":{"ieee":"D.

Force spectroscopy techniques based on the atomic force microscope (AFM) are increasingly used to study the complex visco-elastic response of (bio-)molecules on a single-molecule level. These experiments either require that the AFM cantilever is actively oscillated or that the molecule is clamped at constant force to monitor thermal cantilever motion. Here we demonstrate that the visco-elasticity of single bio-molecules can readily be extracted from the Brownian cantilever motion during conventional force-extension measurements. It is shown that the characteristics of the cantilever determine the signal-to-noise (S/N) ratio and time resolution. Using a small cantilever, the visco-elastic properties of single dextran molecules were resolved with a time resolution of 8.3 ms. The presented approach can be directly applied to probe the dynamic response of complex bio-molecular systems or proteins in force-extension experiments."}],"publist_id":"2500","issue":"3","extern":1}]
