text: Understanding population divergence that eventually leads to speciation is
essential for evolutionary biology. High species diversity in the sea was regarded
as a paradox when strict allopatry was considered necessary for most speciation
events because geographical barriers seemed largely absent in the sea, and many
marine species have high dispersal capacities. Combining genome-wide data with
demographic modelling to infer the demographic history of divergence has introduced
new ways to address this classical issue. These models assume an ancestral population
that splits into two subpopulations diverging according to different scenarios
that allow tests for periods of gene flow. Models can also test for heterogeneities
in population sizes and migration rates along the genome to account, respectively,
for background selection and selection against introgressed ancestry. To investigate
how barriers to gene flow arise in the sea, we compiled studies modelling the
demographic history of divergence in marine organisms and extracted preferred
demographic scenarios together with estimates of demographic parameters. These
studies show that geographical barriers to gene flow do exist in the sea but that
divergence can also occur without strict isolation. Heterogeneity of gene flow
was detected in most population pairs suggesting the predominance of semipermeable
barriers during divergence. We found a weak positive relationship between the
fraction of the genome experiencing reduced gene flow and levels of genome-wide
differentiation. Furthermore, we found that the upper bound of the ‘grey zone
of speciation’ for our dataset extended beyond that found before, implying that
gene flow between diverging taxa is possible at higher levels of divergence than
previously thought. Finally, we list recommendations for further strengthening
the use of demographic modelling in speciation research. These include a more
balanced representation of taxa, more consistent and comprehensive modelling,
clear reporting of results and simulation studies to rule out nonbiological explanations
for general results.

text: Inversions are structural mutations that reverse the sequence of a chromosome
segment and reduce the effective rate of recombination in the heterozygous state.
They play a major role in adaptation, as well as in other evolutionary processes
such as speciation. Although inversions have been studied since the 1920s, they
remain difficult to investigate because the reduced recombination conferred by
them strengthens the effects of drift and hitchhiking, which in turn can obscure
signatures of selection. Nonetheless, numerous inversions have been found to be
under selection. Given recent advances in population genetic theory and empirical
study, here we review how different mechanisms of selection affect the evolution
of inversions. A key difference between inversions and other mutations, such as
single nucleotide variants, is that the fitness of an inversion may be affected
by a larger number of frequently interacting processes. This considerably complicates
the analysis of the causes underlying the evolution of inversions. We discuss
the extent to which these mechanisms can be disentangled, and by which approach.

text: "Chromosomal rearrangements (CRs) have been known since almost the beginning
of genetics.\r\nWhile an important role for CRs in speciation has been suggested,
evidence primarily stems\r\nfrom theoretical and empirical studies focusing on
the microevolutionary level (i.e., on taxon\r\npairs where speciation is often
incomplete). Although the role of CRs in eukaryotic speciation at\r\na macroevolutionary
level has been supported by associations between species diversity and\r\nrates
of evolution of CRs across phylogenies, these findings are limited to a restricted
range of\r\nCRs and taxa. Now that more broadly applicable and precise CR detection
approaches have\r\nbecome available, we address the challenges in filling some
of the conceptual and empirical\r\ngaps between micro- and macroevolutionary studies
on the role of CRs in speciation. We\r\nsynthesize what is known about the macroevolutionary
impact of CRs and suggest new research avenues to overcome the pitfalls of previous
studies to gain a more comprehensive understanding of the evolutionary significance
of CRs in speciation across the tree of life."

text: Understanding the factors that have shaped the current distributions and diversity
of species is a central and longstanding aim of evolutionary biology. The recent
inclusion of genomic data into phylogeographic studies has dramatically improved
our understanding in organisms where evolutionary relationships have been challenging
to infer. We used whole-genome sequences to study the phylogeography of the intertidal
snail Littorina saxatilis, which has successfully colonized and diversified across
a broad range of coastal environments in the Northern Hemisphere amid repeated
cycles of glaciation. Building on past studies based on short DNA sequences, we
used genome-wide data to provide a clearer picture of the relationships among
samples spanning most of the species natural range. Our results confirm the trans-Atlantic
colonization of North America from Europe, and have allowed us to identify rough
locations of glacial refugia and to infer likely routes of colonization within
Europe. We also investigated the signals in different datasets to account for
the effects of genomic architecture and non-neutral evolution, which provides
new insights about diversification of four ecotypes of L. saxatilis (the crab,
wave, barnacle, and brackish ecotypes) at different spatial scales. Overall, we
provide a much clearer picture of the biogeography of L. saxatilis, providing
a foundation for more detailed phylogenomic and demographic studies.

text: Conflict over reproduction between females and males exists because of anisogamy
and promiscuity. Together they generate differences in fitness optima between
the sexes and result in antagonistic coevolution of female and male reproductive
traits. Mounting duration is likely to be a compromise between male and female
interests whose outcome depends on the intensity of sexual selection. The timing
of sperm transfer during mounting is critical. For example, mountings may be interrupted
before sperm is transferred as a consequence of female or male choice, or they
may be prolonged to function as mate guarding. In the highly promiscuous intertidal
snail Littorina saxatilis, mountings vary substantially in duration, from less
than a minute to more than an hour, and it has been assumed that mountings of
a few minutes do not result in any sperm being transferred. Here, we examined
the timing of sperm transfer, a reproductive trait that is likely affected by
sexual conflict. We performed time-controlled mounting trials using L. saxatilis
males and virgin females, aiming to examine indirectly when the transfer of sperm
starts. We observed the relationship between mounting duration and the proportion
of developing embryos out of all eggs and embryos in the brood pouch. Developing
embryos were observed in similar proportions in all treatments (i.e. 1, 5 and
10 or more minutes at which mountings were artificially interrupted), suggesting
that sperm transfer begins rapidly (within 1 min) in L. saxatilis and very short
matings do not result in sperm shortage in the females. We discuss how the observed
pattern can be influenced by predation risk, population density, and female status
and receptivity.

text: Hybridization is a common evolutionary process with multiple possible outcomes.
In vertebrates, interspecific hybridization has repeatedly generated parthenogenetic
hybrid species. However, it is unknown whether the generation of parthenogenetic
hybrids is a rare outcome of frequent hybridization between sexual species within
a genus or the typical outcome of rare hybridization events. Darevskia is a genus
of rock lizards with both hybrid parthenogenetic and sexual species. Using capture
sequencing, we estimate phylogenetic relationships and gene flow among the sexual
species, to determine how introgressive hybridization relates to the origins of
parthenogenetic hybrids. We find evidence for widespread hybridization with gene
flow, both between recently diverged species and deep branches. Surprisingly,
we find no signal of gene flow between parental species of the parthenogenetic
hybrids, suggesting that the parental pairs were either reproductively or geographically
isolated early in their divergence. The generation of parthenogenetic hybrids
in Darevskia is, then, a rare outcome of the total occurrence of hybridization
within the genus, but the typical outcome when specific species pairs hybridize.
Our results question the conventional view that parthenogenetic lineages are generated
by hybridization in a window of divergence. Instead, they suggest that some lineages
possess specific properties that underpin successful parthenogenetic reproduction.

text: Local adaptation leads to differences between populations within a species.
In many systems, similar environmental contrasts occur repeatedly, sometimes driving
parallel phenotypic evolution. Understanding the genomic basis of local adaptation
and parallel evolution is a major goal of evolutionary genomics. It is now known
that by preventing the break-up of favourable combinations of alleles across multiple
loci, genetic architectures that reduce recombination, like chromosomal inversions,
can make an important contribution to local adaptation. However, little is known
about whether inversions also contribute disproportionately to parallel evolution.
Our aim here is to highlight this knowledge gap, to showcase existing studies,
and to illustrate the differences between genomic architectures with and without
inversions using simple models. We predict that by generating stronger effective
selection, inversions can sometimes speed up the parallel adaptive process or
enable parallel adaptation where it would be impossible otherwise, but this is
highly dependent on the spatial setting. We highlight that further empirical work
is needed, in particular to cover a broader taxonomic range and to understand
the relative importance of inversions compared to genomic regions without inversions.

text: Chromosomal inversions have been shown to play a major role in local adaptation
by suppressing recombination between alternative arrangements and maintaining
beneficial allele combinations. However, so far, their importance relative to
the remaining genome remains largely unknown. Understanding the genetic architecture
of adaptation requires better estimates of how loci of different effect sizes
contribute to phenotypic variation. Here, we used three Swedish islands where
the marine snail Littorina saxatilis has repeatedly evolved into two distinct
ecotypes along a habitat transition. We estimated the contribution of inversion
polymorphisms to phenotypic divergence while controlling for polygenic effects
in the remaining genome using a quantitative genetics framework. We confirmed
the importance of inversions but showed that contributions of loci outside inversions
are of similar magnitude, with variable proportions dependent on the trait and
the population. Some inversions showed consistent effects across all sites, whereas
others exhibited site-specific effects, indicating that the genomic basis for
replicated phenotypic divergence is only partly shared. The contributions of sexual
dimorphism as well as environmental factors to phenotypic variation were significant
but minor compared to inversions and polygenic background. Overall, this integrated
approach provides insight into the multiple mechanisms contributing to parallel
phenotypic divergence.

text: 'Sexual antagonism is a common hypothesis for driving the evolution of sex
chromosomes, whereby recombination suppression is favored between sexually antagonistic
loci and the sex-determining locus to maintain beneficial combinations of alleles.
This results in the formation of a sex-determining region. Chromosomal inversions
may contribute to recombination suppression but their precise role in sex chromosome
evolution remains unclear. Because local adaptation is frequently facilitated
through the suppression of recombination between adaptive loci by chromosomal
inversions, there is potential for inversions that cover sex-determining regions
to be involved in local adaptation as well, particularly if habitat variation
creates environment-dependent sexual antagonism. With these processes in mind,
we investigated sex determination in a well-studied example of local adaptation
within a species: the intertidal snail, Littorina saxatilis. Using SNP data from
a Swedish hybrid zone, we find novel evidence for a female-heterogametic sex determination
system that is restricted to one ecotype. Our results suggest that four putative
chromosomal inversions, two previously described and two newly discovered, span
the putative sex chromosome pair. We determine their differing associations with
sex, which suggest distinct strata of differing ages. The same inversions are
found in the second ecotype but do not show any sex association. The striking
disparity in inversion-sex associations between ecotypes that are connected by
gene flow across a habitat transition that is just a few meters wide indicates
a difference in selective regime that has produced a distinct barrier to the spread
of the newly discovered sex-determining region between ecotypes. Such sex chromosome-environment
interactions have not previously been uncovered in L. saxatilis and are known
in few other organisms. A combination of both sex-specific selection and divergent
natural selection is required to explain these highly unusual patterns.'

text: Chromosomal inversions have been shown to play a major role in a local adaptation
by suppressing recombination between alternative arrangements and maintaining
beneficial allele combinations. However, so far, their importance relative to
the remaining genome remains largely unknown. Understanding the genetic architecture
of adaptation requires better estimates of how loci of different effect sizes
contribute to phenotypic variation. Here, we used three Swedish islands where
the marine snail Littorina saxatilis has repeatedly evolved into two distinct
ecotypes along a habitat transition. We estimated the contribution of inversion
polymorphisms to phenotypic divergence while controlling for polygenic effects
in the remaining genome using a quantitative genetics framework. We confirmed
the importance of inversions but showed that contributions of loci outside inversions
are of similar magnitude, with variable proportions dependent on the trait and
the population. Some inversions showed consistent effects across all sites, whereas
others exhibited site-specific effects, indicating that the genomic basis for
replicated phenotypic divergence is only partly shared. The contributions of sexual
dimorphism as well as environmental factors to phenotypic variation were significant
but minor compared to inversions and polygenic background. Overall, this integrated
approach provides insight into the multiple mechanisms contributing to parallel
phenotypic divergence.

text: Reproductive isolation (RI) is a core concept in evolutionary biology. It
has been the central focus of speciation research since the modern synthesis and
is the basis by which biological species are defined. Despite this, the term is
used in seemingly different ways, and attempts to quantify RI have used very different
approaches. After showing that the field lacks a clear definition of the term,
we attempt to clarify key issues, including what RI is, how it can be quantified
in principle, and how it can be measured in practice. Following other definitions
with a genetic focus, we propose that RI is a quantitative measure of the effect
that genetic differences between populations have on gene flow. Specifically,
RI compares the flow of neutral alleles in the presence of these genetic differences
to the flow without any such differences. RI is thus greater than zero when genetic
differences between populations reduce the flow of neutral alleles between populations.
We show how RI can be quantified in a range of scenarios. A key conclusion is
that RI depends strongly on circumstances—including the spatial, temporal and
genomic context—making it difficult to compare across systems. After reviewing
methods for estimating RI from data, we conclude that it is difficult to measure
in practice. We discuss our findings in light of the goals of speciation research
and encourage the use of methods for estimating RI that integrate organismal and
genetic approaches.

text: Combining hybrid zone analysis with genomic data is a promising approach to
understanding the genomic basis of adaptive divergence. It allows for the identification
of genomic regions underlying barriers to gene flow. It also provides insights
into spatial patterns of allele frequency change, informing about the interplay
between environmental factors, dispersal and selection. However, when only a single
hybrid zone is analysed, it is difficult to separate patterns generated by selection
from those resulting from chance. Therefore, it is beneficial to look for repeatable
patterns across replicate hybrid zones in the same system. We applied this approach
to the marine snail Littorina saxatilis, which contains two ecotypes, adapted
to wave-exposed rocks vs. high-predation boulder fields. The existence of numerous
hybrid zones between ecotypes offered the opportunity to test for the repeatability
of genomic architectures and spatial patterns of divergence. We sampled and phenotyped
snails from seven replicate hybrid zones on the Swedish west coast and genotyped
them for thousands of single nucleotide polymorphisms. Shell shape and size showed
parallel clines across all zones. Many genomic regions showing steep clines and/or
high differentiation were shared among hybrid zones, consistent with a common
evolutionary history and extensive gene flow between zones, and supporting the
importance of these regions for divergence. In particular, we found that several
large putative inversions contribute to divergence in all locations. Additionally,
we found evidence for consistent displacement of clines from the boulder–rock
transition. Our results demonstrate patterns of spatial variation that would not
be accessible without continuous spatial sampling, a large genomic data set and
replicate hybrid zones.

text: Hybrid zones are narrow geographic regions where different populations, races
or interbreeding species meet and mate, producing mixed ‘hybrid’ offspring. They
are relatively common and can be found in a diverse range of organisms and environments.
The study of hybrid zones has played an important role in our understanding of
the origin of species, with hybrid zones having been described as ‘natural laboratories’.
This is because they allow us to study,in situ, the conditions and evolutionary
forces that enable divergent taxa to remain distinct despite some ongoing gene
exchange between them.

text: 'Chromosomal inversions have long been recognized for their role in local
adaptation. By suppressing recombination in heterozygous individuals, they can
maintain coadapted gene complexes and protect them from homogenizing effects of
gene flow. However, to fully understand their importance for local adaptation
we need to know their influence on phenotypes under divergent selection. For this,
the marine snail Littorina saxatilis provides an ideal study system. Divergent
ecotypes adapted to wave action and crab predation occur in close proximity on
intertidal shores with gene flow between them. Here, we used F2 individuals obtained
from crosses between the ecotypes to test for associations between genomic regions
and traits distinguishing the Crab‐/Wave‐adapted ecotypes including size, shape,
shell thickness, and behavior. We show that most of these traits are influenced
by two previously detected inversion regions that are divergent between ecotypes.
We thus gain a better understanding of one important underlying mechanism responsible
for the rapid and repeated formation of ecotypes: divergent selection acting on
inversions. We also found that some inversions contributed to more than one trait
suggesting that they may contain several loci involved in adaptation, consistent
with the hypothesis that suppression of recombination within inversions facilitates
differentiation in the presence of gene flow.'

text: A key step in understanding the genetic basis of different evolutionary outcomes
(e.g., adaptation) is to determine the roles played by different mutation types
(e.g., SNPs, translocations and inversions). To do this we must simultaneously
consider different mutation types in an evolutionary framework. Here, we propose
a research framework that directly utilizes the most important characteristics
of mutations, their population genetic effects, to determine their relative evolutionary
significance in a given scenario. We review known population genetic effects of
different mutation types and show how these may be connected to different evolutionary
outcomes. We provide examples of how to implement this framework and pinpoint
areas where more data, theory and synthesis are needed. Linking experimental and
theoretical approaches to examine different mutation types simultaneously is a
critical step towards understanding their evolutionary significance.

text: Chromosomal inversion polymorphisms, segments of chromosomes that are flipped
in orientation and occur in reversed order in some individuals, have long been
recognized to play an important role in local adaptation. They can reduce recombination
in heterozygous individuals and thus help to maintain sets of locally adapted
alleles. In a wide range of organisms, populations adapted to different habitats
differ in frequency of inversion arrangements. However, getting a full understanding
of the importance of inversions for adaptation requires confirmation of their
influence on traits under divergent selection. Here, we studied a marine snail,
Littorina saxatilis, that has evolved ecotypes adapted to wave exposure or crab
predation. These two types occur in close proximity on different parts of the
shore. Gene flow between them exists in contact zones. However, they exhibit strong
phenotypic divergence in several traits under habitat-specific selection, including
size, shape and behaviour. We used crosses between these ecotypes to identify
genomic regions that explain variation in these traits by using QTL analysis and
variance partitioning across linkage groups. We could show that previously detected
inversion regions contribute to adaptive divergence. Some inversions influenced
multiple traits suggesting that they contain sets of locally adaptive alleles.
Our study also identified regions without known inversions that are important
for phenotypic divergence. Thus, we provide a more complete overview of the importance
of inversions in relation to the remaining genome.

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: 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.
