text: The Mytilus complex of marine mussel species forms a mosaic of hybrid zones,
found across temperate regions of the globe. This allows us to study "replicated"
instances of secondary contact between closely-related species. Previous work
on this complex has shown that local introgression is both widespread and highly
heterogeneous, and has identified SNPs that are outliers of differentiation between
lineages. Here, we developed an ancestry-informative panel of such SNPs. We then
compared their frequencies in newly-sampled populations, including samples from
within the hybrid zones, and parental populations at different distances from
the contact. Results show that close to the hybrid zones, some outlier loci are
near to fixation for the heterospecific allele, suggesting enhanced local introgression,
or the local sweep of a shared ancestral allele. Conversely, genomic cline analyses,
treating local parental populations as the reference, reveal a globally high concordance
among loci, albeit with a few signals of asymmetric introgression. Enhanced local
introgression at specific loci is consistent with the early transfer of adaptive
variants after contact, possibly including asymmetric bi-stable variants (Dobzhansky-Muller
incompatibilities), or haplotypes loaded with fewer deleterious mutations. Having
escaped one barrier, however, these variants can be trapped or delayed at the
next barrier, confining the introgression locally. These results shed light on
the decay of species barriers during phases of contact.

text: Domestication is a human-induced selection process that imprints the genomes
of domesticated populations over a short evolutionary time scale, and that occurs
in a given demographic context. Reconstructing historical gene flow, effective
population size changes and their timing is therefore of fundamental interest
to understand how plant demography and human selection jointly shape genomic divergence
during domestication. Yet, the comparison under a single statistical framework
of independent domestication histories across different crop species has been
little evaluated so far. Thus, it is unclear whether domestication leads to convergent
demographic changes that similarly affect crop genomes. To address this question,
we used existing and new transcriptome data on three crop species of Solanaceae
(eggplant, pepper and tomato), together with their close wild relatives. We fitted
twelve demographic models of increasing complexity on the unfolded joint allele
frequency spectrum for each wild/crop pair, and we found evidence for both shared
and species-specific demographic processes between species. A convergent history
of domestication with gene-flow was inferred for all three species, along with
evidence of strong reduction in the effective population size during the cultivation
stage of tomato and pepper. The absence of any reduction in size of the crop in
eggplant stands out from the classical view of the domestication process; as does
the existence of a “protracted period” of management before cultivation. Our results
also suggest divergent management strategies of modern cultivars among species
as their current demography substantially differs. Finally, the timing of domestication
is species-specific and supported by the few historical records available.

text: When divergent populations are connected by gene flow, the establishment of
complete reproductive isolation usually requires the joint action of multiple
barrier effects. One example where multiple barrier effects are coupled consists
of a single trait that is under divergent natural selection and also mediates
assortative mating. Such multiple‐effect traits can strongly reduce gene flow.
However, there are few cases where patterns of assortative mating have been described
quantitatively and their impact on gene flow has been determined. Two ecotypes
of the coastal marine snail, Littorina saxatilis , occur in North Atlantic rocky‐shore
habitats dominated by either crab predation or wave action. There is evidence
for divergent natural selection acting on size, and size‐assortative mating has
previously been documented. Here, we analyze the mating pattern in L. saxatilis
with respect to size in intensively sampled transects across boundaries between
the habitats. We show that the mating pattern is mostly conserved between ecotypes
and that it generates both assortment and directional sexual selection for small
male size. Using simulations, we show that the mating pattern can contribute to
reproductive isolation between ecotypes but the barrier to gene flow is likely
strengthened more by sexual selection than by assortment.

text: Speciation, that is, the evolution of reproductive barriers eventually leading
to complete isolation, is a crucial process generating biodiversity. Recent work
has contributed much to our understanding of how reproductive barriers begin to
evolve, and how they are maintained in the face of gene flow. However, little
is known about the transition from partial to strong reproductive isolation (RI)
and the completion of speciation. We argue that the evolution of strong RI is
likely to involve different processes, or new interactions among processes, compared
with the evolution of the first reproductive barriers. Transition to strong RI
may be brought about by changing external conditions, for example, following secondary
contact. However, the increasing levels of RI themselves create opportunities
for new barriers to evolve and, and interaction or coupling among barriers. These
changing processes may depend on genomic architecture and leave detectable signals
in the genome. We outline outstanding questions and suggest more theoretical and
empirical work, considering both patterns and processes associated with strong
RI, is needed to understand how speciation is completed.

text: The evolution of strong reproductive isolation (RI) is fundamental to the
origins and maintenance of biological diversity, especially in situations where
geographical distributions of taxa broadly overlap. But what is the history behind
strong barriers currently acting in sympatry? Using whole-genome sequencing and
single nucleotide polymorphism genotyping, we inferred (i) the evolutionary relationships,
(ii) the strength of RI, and (iii) the demographic history of divergence between
two broadly sympatric taxa of intertidal snail. Despite being cryptic, based on
external morphology, Littorina arcana and Littorina saxatilis differ in their
mode of female reproduction (egg-laying versus brooding), which may generate a
strong post-zygotic barrier. We show that egg-laying and brooding snails are closely
related, but genetically distinct. Genotyping of 3092 snails from three locations
failed to recover any recent hybrid or backcrossed individuals, confirming that
RI is strong. There was, however, evidence for a very low level of asymmetrical
introgression, suggesting that isolation remains incomplete. The presence of strong,
asymmetrical RI was further supported by demographic analysis of these populations.
Although the taxa are currently broadly sympatric, demographic modelling suggests
that they initially diverged during a short period of geographical separation
involving very low gene flow. Our study suggests that some geographical separation
may kick-start the evolution of strong RI, facilitating subsequent coexistence
of taxa in sympatry. The strength of RI needed to achieve sympatry and the subsequent
effect of sympatry on RI remain open questions.

text: Many recent studies have addressed the mechanisms operating during the early
stages of speciation, but surprisingly few studies have tested theoretical predictions
on the evolution of strong reproductive isolation (RI). To help address this gap,
we first undertook a quantitative review of the hybrid zone literature for flowering
plants in relation to reproductive barriers. Then, using Populus as an exemplary
model group, we analysed genome-wide variation for phylogenetic tree topologies
in both early- and late-stage speciation taxa to determine how these patterns
may be related to the genomic architecture of RI. Our plant literature survey
revealed variation in barrier complexity and an association between barrier number
and introgressive gene flow. Focusing on Populus, our genome-wide analysis of
tree topologies in speciating poplar taxa points to unusually complex genomic
architectures of RI, consistent with earlier genome-wide association studies.
These architectures appear to facilitate the ‘escape’ of introgressed genome segments
from polygenic barriers even with strong RI, thus affecting their relationships
with recombination rates. Placed within the context of the broader literature,
our data illustrate how phylogenomic approaches hold great promise for addressing
the evolution and temporary breakdown of RI during late stages of speciation.

text: Fitness interactions between mutations can influence a population’s evolution
in many different ways. While epistatic effects are difficult to measure precisely,
important information is captured by the mean and variance of log fitnesses for
individuals carrying different numbers of mutations. We derive predictions for
these quantities from a class of simple fitness landscapes, based on models of
optimizing selection on quantitative traits. We also explore extensions to the
models, including modular pleiotropy, variable effect sizes, mutational bias and
maladaptation of the wild type. We illustrate our approach by reanalysing a large
dataset of mutant effects in a yeast snoRNA. Though characterized by some large
epistatic effects, these data give a good overall fit to the non-epistatic null
model, suggesting that epistasis might have limited influence on the evolutionary
dynamics in this system. We also show how the amount of epistasis depends on both
the underlying fitness landscape and the distribution of mutations, and so is
expected to vary in consistent ways between new mutations, standing variation
and fixed mutations.

text: The biotic interactions hypothesis posits that biotic interactions are more
important drivers of adaptation closer to the equator, evidenced by “stronger”
contemporary interactions (e.g. greater interaction rates) and/or patterns of
trait evolution consistent with a history of stronger interactions. Support for
the hypothesis is mixed, but few studies span tropical and temperate regions while
experimentally controlling for evolutionary history. Here, we integrate field
observations and common garden experiments to quantify the relative importance
of pollination and herbivory in a pair of tropical‐temperate congeneric perennial
herbs. Phytolacca rivinoides and P. americana are pioneer species native to the
Neotropics and the eastern USA, respectively. We compared plant‐pollinator and
plant‐herbivore interactions between three tropical populations of P. rivinoides
from Costa Rica and three temperate populations of P. americana from its northern
range edge in Michigan and Ohio. For some metrics of interaction importance, we
also included three subtropical populations of P. americana from its southern
range edge in Florida. This approach confounds species and region but allows us,
uniquely, to measure complementary proxies of interaction importance across a
tropical‐temperate range in one system. To test the prediction that lower‐latitude
plants are more reliant on insect pollinators, we quantified floral display and
reward, insect visitation rates, and self‐pollination ability (autogamy). To test
the prediction that lower‐latitude plants experience more herbivore pressure,
we quantified herbivory rates, herbivore abundance, and leaf palatability. We
found evidence supporting the biotic interactions hypothesis for most comparisons
between P. rivinoides and north‐temperate P. americana (floral display, insect
visitation, autogamy, herbivory, herbivore abundance, and young‐leaf palatability).
Results for subtropical P. americana populations, however, were typically not
intermediate between P. rivinoides and north‐temperate P. americana, as would
be predicted by a linear latitudinal gradient in interaction importance. Subtropical
young‐leaf palatability was intermediate, but subtropical mature leaves were the
least palatable, and pollination‐related traits did not differ between temperate
and subtropical regions. These nonlinear patterns of interaction importance suggest
future work to relate interaction importance to climatic or biotic thresholds.
In sum, we found that the biotic interactions hypothesis was more consistently
supported at the larger spatial scale of our study.

text: Genetic incompatibilities contribute to reproductive isolation between many
diverging populations, but it is still unclear to what extent they play a role
if divergence happens with gene flow. In contact zones between the "Crab" and
"Wave" ecotypes of the snail Littorina saxatilis, divergent selection forms strong
barriers to gene flow, while the role of post‐zygotic barriers due to selection
against hybrids remains unclear. High embryo abortion rates in this species could
indicate the presence of such barriers. Post‐zygotic barriers might include genetic
incompatibilities (e.g. Dobzhansky–Muller incompatibilities) but also maladaptation,
both expected to be most pronounced in contact zones. In addition, embryo abortion
might reflect physiological stress on females and embryos independent of any genetic
stress. We examined all embryos of >500 females sampled outside and inside contact
zones of three populations in Sweden. Females' clutch size ranged from 0 to 1,011
embryos (mean 130 ± 123), and abortion rates varied between 0% and 100% (mean
12%). We described female genotypes by using a hybrid index based on hundreds
of SNPs differentiated between ecotypes with which we characterized female genotypes.
We also calculated female SNP heterozygosity and inversion karyotype. Clutch size
did not vary with female hybrid index, and abortion rates were only weakly related
to hybrid index in two sites but not at all in a third site. No additional variation
in abortion rate was explained by female SNP heterozygosity, but increased female
inversion heterozygosity added slightly to increased abortion. Our results show
only weak and probably biologically insignificant post‐zygotic barriers contributing
to ecotype divergence, and the high and variable abortion rates were marginally,
if at all, explained by hybrid index of females.

text: "This thesis concerns itself with the interactions of evolutionary and ecological
forces and the consequences on genetic diversity and the ultimate survival of
populations. It is important to understand what signals processes \r\nleave on
the genome and what we can infer from such data, which is usually abundant but
noisy. Furthermore, understanding how and when populations adapt or go extinct
is important for practical purposes, such as the genetic management of populations,
as well as for theoretical questions, since local adaptation can be the first
step toward speciation. \r\nIn Chapter 2, we introduce the method of maximum entropy
to approximate the demographic changes of a population in a simple setting, namely
the logistic growth model with immigration. We show that this method is not only
a powerful \r\ntool in physics but can be gainfully applied in an ecological framework.
We investigate how well it approximates the real \r\nbehavior of the system, and
find that is does so, even in unexpected situations. Finally, we illustrate how
it can model changing environments.\r\nIn Chapter 3, we analyze the co-evolution
of allele frequencies and population sizes in an infinite island model.\r\nWe
give conditions under which polygenic adaptation to a rare habitat is possible.
The model we use is based on the diffusion approximation, considers eco-evolutionary
feedback mechanisms (hard selection), and treats both \r\ndrift and environmental
fluctuations explicitly. We also look at limiting scenarios, for which we derive
analytical expressions. \r\nIn Chapter 4, we present a coalescent based simulation
tool to obtain patterns of diversity in a spatially explicit subdivided population,
in which the demographic history of each subpopulation can be specified. We compare
\r\nthe results to existing predictions, and explore the relative importance of
time and space under a variety of spatial arrangements and demographic histories,
such as expansion and extinction. \r\nIn the last chapter, we give a brief outlook
to further research. "

text: 'More than 100 years after Grigg’s influential analysis of species’ borders,
the causes of limits to species’ ranges still represent a puzzle that has never
been understood with clarity. The topic has become especially important recently
as many scientists have become interested in the potential for species’ ranges
to shift in response to climate change—and yet nearly all of those studies fail
to recognise or incorporate evolutionary genetics in a way that relates to theoretical
developments. I show that range margins can be understood based on just two measurable
parameters: (i) the fitness cost of dispersal—a measure of environmental heterogeneity—and
(ii) the strength of genetic drift, which reduces genetic diversity. Together,
these two parameters define an ‘expansion threshold’: adaptation fails when genetic
drift reduces genetic diversity below that required for adaptation to a heterogeneous
environment. When the key parameters drop below this expansion threshold locally,
a sharp range margin forms. When they drop below this threshold throughout the
species’ range, adaptation collapses everywhere, resulting in either extinction
or formation of a fragmented metapopulation. Because the effects of dispersal
differ fundamentally with dimension, the second parameter—the strength of genetic
drift—is qualitatively different compared to a linear habitat. In two-dimensional
habitats, genetic drift becomes effectively independent of selection. It decreases
with ‘neighbourhood size’—the number of individuals accessible by dispersal within
one generation. Moreover, in contrast to earlier predictions, which neglected
evolution of genetic variance and/or stochasticity in two dimensions, dispersal
into small marginal populations aids adaptation. This is because the reduction
of both genetic and demographic stochasticity has a stronger effect than the cost
of dispersal through increased maladaptation. The expansion threshold thus provides
a novel, theoretically justified, and testable prediction for formation of the
range margin and collapse of the species’ range.'

text: Empirical data suggest that inversions in many species contain genes important
for intraspecific divergence and speciation, yet mechanisms of evolution remain
unclear. While genes inside an inversion are tightly linked, inversions are not
static but evolve separately from the rest of the genome by new mutations, recombination
within arrangements, and gene flux between arrangements. Inversion polymorphisms
are maintained by different processes, for example, divergent or balancing selection,
or a mix of multiple processes. Moreover, the relative roles of selection, drift,
mutation, and recombination will change over the lifetime of an inversion and
within its area of distribution. We believe inversions are central to the evolution
of many species, but we need many more data and new models to understand the complex
mechanisms involved.

text: Pollinators display a remarkable diversity of foraging strategies with flowering
plants, from primarily mutualistic interactions to cheating through nectar robbery.
Despite numerous studies on the effect of nectar robbing on components of plant
fitness, its contribution to reproductive isolation is unclear. We experimentally
tested the impact of different pollinator strategies in a natural hybrid zone
between two subspecies of Antirrhinum majus with alternate flower colour guides.
On either side of a steep cline in flower colour between Antirrhinum majus pseudomajus
(magenta) and A. m. striatum (yellow), we quantified the behaviour of all floral
visitors at different time points during the flowering season. Using long-run
camera surveys, we quantify the impact of nectar robbing on the number of flowers
visited per inflorescence and the flower probing time. We further experimentally
tested the effect of nectar robbing on female reproductive success by manipulating
the intensity of robbing. While robbing increased over time the number of legitimate
visitors tended to decrease concomitantly. We found that the number of flowers
pollinated on a focal inflorescence decreased with the number of prior robbing
events. However, in the manipulative experiment, fruit set and fruit volume did
not vary significantly between low robbing and control treatments. Our findings
challenge the idea that robbers have a negative impact on plant fitness through
female function. This study also adds to our understanding of the components of
pollinator-mediated reproductive isolation and the maintenance of Antirrhinum
hybrid zones.

text: The evolution of new species is made easier when traits under divergent ecological
selection are also mating cues. Such ecological mating cues are now considered
more common than previously thought, but we still know little about the genetic
changes underlying their evolution or more generally about the genetic basis for
assortative mating behaviors. Both tight physical linkage and the existence of
large-effect preference loci will strengthen genetic associations between behavioral
and ecological barriers, promoting the evolution of assortative mating. The warning
patterns of Heliconius melpomene and H. cydno are under disruptive selection due
to increased predation of nonmimetic hybrids and are used during mate recognition.
We carried out a genome-wide quantitative trait locus (QTL) analysis of preference
behaviors between these species and showed that divergent male preference has
a simple genetic basis. We identify three QTLs that together explain a large proportion
(approximately 60%) of the difference in preference behavior observed between
the parental species. One of these QTLs is just 1.2 (0-4.8) centiMorgans (cM)
from the major color pattern gene optix, and, individually, all three have a large
effect on the preference phenotype. Genomic divergence between H. cydno and H.
melpomene is high but broadly heterogenous, and admixture is reduced at the preference-optix
color pattern locus but not the other preference QTLs. The simple genetic architecture
we reveal will facilitate the evolution and maintenance of new species despite
ongoing gene flow by coupling behavioral and ecological aspects of reproductive
isolation.

text: Both classical and recent studies suggest that chromosomal inversion polymorphisms
are important in adaptation and speciation. However, biases in discovery and reporting
of inversions make it difficult to assess their prevalence and biological importance.
Here, we use an approach based on linkage disequilibrium among markers genotyped
for samples collected across a transect between contrasting habitats to detect
chromosomal rearrangements de novo. We report 17 polymorphic rearrangements in
a single locality for the coastal marine snail, Littorina saxatilis. Patterns
of diversity in the field and of recombination in controlled crosses provide strong
evidence that at least the majority of these rearrangements are inversions. Most
show clinal changes in frequency between habitats, suggestive of divergent selection,
but only one appears to be fixed for different arrangements in the two habitats.
Consistent with widespread evidence for balancing selection on inversion polymorphisms,
we argue that a combination of heterosis and divergent selection can explain the
observed patterns and should be considered in other systems spanning environmental
gradients.
