text: 'For self-incompatibility (SI) to be stable in a population, theory predicts
that sufficient inbreeding depression (ID) is required: the fitness of offspring
from self-mated individuals must be low enough to prevent the spread of self-compatibility
(SC). Reviews of natural plant populations have supported this theory, with SI
species generally showing high levels of ID. However, there is thought to be an
under-sampling of self-incompatible taxa in the current literature. In this thesis,
I study inbreeding depression in the SI plant species Antirrhinum majus using
both greenhouse crosses and a large collected field dataset. Additionally, the
gametophytic S-locus of A. majus is highly heterozygous and polymorphic, thus
making assembly and discovery of S-alleles very difficult. Here, 206 new alleles
of the male component SLFs are presented, along with a phylogeny showing the high
conservation with alleles from another Antirrhinum species. Lastly, selected sites
within the protein structure of SLFs are investigated, with one site in particular
highlighted as potentially being involved in the SI recognition mechanism.'

text: 'Fragmented landscapes pose a significant threat to the persistence of species
as they are highly susceptible to heightened risk of extinction due to the combined
effects of genetic and demographic factors such as genetic drift and demographic
stochasticity. This paper explores the intricate interplay between genetic load
and extinction risk within metapopulations with a focus on understanding the impact
of eco-evolutionary feedback mechanisms. We distinguish between two models of
selection: soft selection, characterised by subpopulations maintaining carrying
capacity despite load, and hard selection, where load can significantly affect
population size. Within the soft selection framework, we investigate the impact
of gene flow on genetic load at a single locus, while also considering the effect
of selection strength and dominance coefficient. We subsequently build on this
to examine how gene flow influences both population size and load under hard selection
as well as identify critical thresholds for metapopulation persistence. Our analysis
employs the diffusion, semi-deterministic and effective migration approximations.
Our findings reveal that under soft selection, even modest levels of migration
can significantly alleviate the burden of load. In sharp contrast, with hard selection,
a much higher degree of gene flow is required to mitigate load and prevent the
collapse of the metapopulation. Overall, this study sheds light into the crucial
role migration plays in shaping the dynamics of genetic load and extinction risk
in fragmented landscapes, offering valuable insights for conservation strategies
and the preservation of diversity in a changing world.'

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 phenotypic and genetic architecture of reproductive isolation
is a long‐standing goal of speciation research. In several systems, large‐effect
loci contributing to barrier phenotypes have been characterized, but such causal
connections are rarely known for more complex genetic architectures. In this study,
we combine “top‐down” and “bottom‐up” approaches with demographic modelling toward
an integrated understanding of speciation across a monkeyflower hybrid zone. Previous
work suggests that pollinator visitation acts as a primary barrier to gene flow
between two divergent red‐ and yellow‐flowered ecotypes ofMimulus
aurantiacus. Several candidate isolating traits and anonymous single
nucleotide polymorphism loci under divergent selection have been identified, but
their genomic positions remain unknown. Here, we report findings from demographic
analyses that indicate this hybrid zone formed by secondary contact, but that
subsequent gene flow was restricted by widespread barrier loci across the genome.
Using a novel, geographic cline‐based genome scan, we demonstrate that candidate
barrier loci are broadly distributed across the genome, rather than mapping to
one or a few “islands of speciation.” Quantitative trait locus (QTL) mapping reveals
that most floral traits are highly polygenic, with little evidence that QTL colocalize,
indicating that most traits are genetically independent. Finally, we find little
evidence that QTL and candidate barrier loci overlap, suggesting that some loci
contribute to other forms of reproductive isolation. Our findings highlight the
challenges of understanding the genetic architecture of reproductive isolation
and reveal that barriers to gene flow other than pollinator isolation may play
an important role in this system.

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: 'The evolutionary processes that brought about today’s plethora of living
species and the many billions more ancient ones all underlie biology. Evolutionary
pathways are neither directed nor deterministic, but rather an interplay between
selection, migration, mutation, genetic drift and other environmental factors.
Hybrid zones, as natural crossing experiments, offer a great opportunity to use
cline analysis to deduce different evolutionary processes - for example, selection
strength. Theoretical cline models, largely assuming uniform distribution of individuals,
often lack the capability of incorporating population structure. Since in reality
organisms mostly live in patchy distributions and their dispersal is hardly ever
Gaussian, it is necessary to unravel the effect of these different elements of
population structure on cline parameters and shape. In this thesis, I develop
a simulation inspired by the A. majus hybrid zone of a single selected locus under
frequency dependent selection. This simulation enables us to untangle the effects
of different elements of population structure as for example a low-density center
and long-range dispersal. This thesis is therefore a first step towards theoretically
untangling the effects of different elements of population structure on cline
parameters and shape. '

text: The term “haplotype block” is commonly used in the developing field of haplotype-based
inference methods. We argue that the term should be defined based on the structure
of the Ancestral Recombination Graph (ARG), which contains complete information
on the ancestry of a sample. We use simulated examples to demonstrate key features
of the relationship between haplotype blocks and ancestral structure, emphasizing
the stochasticity of the processes that generate them. Even the simplest cases
of neutrality or of a “hard” selective sweep produce a rich structure, often missed
by commonly used statistics. We highlight a number of novel methods for inferring
haplotype structure, based on the full ARG, or on a sequence of trees, and illustrate
how they can be used to define haplotype blocks using an empirical data set. While
the advent of new, computationally efficient methods makes it possible to apply
these concepts broadly, they (and additional new methods) could benefit from adding
features to explore haplotype blocks, as we define them. Understanding and applying
the concept of the haplotype block will be essential to fully exploit long and
linked-read sequencing technologies.

text: "Although we often see studies focusing on simple or even discrete traits
in studies of colouration,\r\nthe variation of “appearance” phenotypes found in
nature is often more complex, continuous\r\nand high-dimensional. Therefore, we
developed automated methods suitable for large datasets\r\nof genomes and images,
striving to account for their complex nature, while minimising human\r\nbias.
We used these methods on a dataset of more than 20, 000 plant SNP genomes and\r\ncorresponding
fower images from a hybrid zone of two subspecies of Antirrhinum majus with\r\ndistinctly
coloured fowers to improve our understanding of the genetic nature of the fower\r\ncolour
in our study system.\r\nFirstly, we use the advantage of large numbers of genotyped
plants to estimate the haplotypes in\r\nthe main fower colour regulating region.
We study colour- and geography-related characteristics\r\nof the estimated haplotypes
and how they connect to their relatedness. We show discrepancies\r\nfrom the expected
fower colour distributions given the genotype and identify particular\r\nhaplotypes
leading to unexpected phenotypes. We also confrm a signifcant defcit of the\r\ndouble
recessive recombinant and quite surprisingly, we show that haplotypes of the most\r\nfrequent
parental type are much less variable than others.\r\nSecondly, we introduce our
pipeline capable of processing tens of thousands of full fower\r\nimages without
human interaction and summarising each image into a set of informative scores.\r\nWe
show the compatibility of these machine-measured fower colour scores with the
previously\r\nused manual scores and study impact of external efect on the resulting
scores. Finally, we use\r\nthe machine-measured fower colour scores to ft and
examine a phenotype cline across the\r\nhybrid zone in Planoles using full fower
images as opposed to discrete, manual scores and\r\ncompare it with the genotypic
cline."

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: Many studies have quantified the distribution of heterozygosity and relatedness
in natural populations, but few have examined the demographic processes driving
these patterns. In this study, we take a novel approach by studying how population
structure affects both pairwise identity and the distribution of heterozygosity
in a natural population of the self-incompatible plant Antirrhinum majus. Excess
variance in heterozygosity between individuals is due to identity disequilibrium,
which reflects the variance in inbreeding between individuals; it is measured
by the statistic g2. We calculated g2 together with FST and pairwise relatedness
(Fij) using 91 SNPs in 22,353 individuals collected over 11 years. We find that
pairwise Fij declines rapidly over short spatial scales, and the excess variance
in heterozygosity between individuals reflects significant variation in inbreeding.
Additionally, we detect an excess of individuals with around half the average
heterozygosity, indicating either selfing or matings between close relatives.
We use 2 types of simulation to ask whether variation in heterozygosity is consistent
with fine-scale spatial population structure. First, by simulating offspring using
parents drawn from a range of spatial scales, we show that the known pollen dispersal
kernel explains g2. Second, we simulate a 1,000-generation pedigree using the
known dispersal and spatial distribution and find that the resulting g2 is consistent
with that observed from the field data. In contrast, a simulated population with
uniform density underestimates g2, indicating that heterogeneous density promotes
identity disequilibrium. Our study shows that heterogeneous density and leptokurtic
dispersal can together explain the distribution of heterozygosity.

text: Empirical essays of fitness landscapes suggest that they may be rugged, that
is having multiple fitness peaks. Such fitness landscapes, those that have multiple
peaks, necessarily have special local structures, called reciprocal sign epistasis
(Poelwijk et al. in J Theor Biol 272:141–144, 2011). Here, we investigate the
quantitative relationship between the number of fitness peaks and the number of
reciprocal sign epistatic interactions. Previously, it has been shown (Poelwijk
et al. in J Theor Biol 272:141–144, 2011) that pairwise reciprocal sign epistasis
is a necessary but not sufficient condition for the existence of multiple peaks.
Applying discrete Morse theory, which to our knowledge has never been used in
this context, we extend this result by giving the minimal number of reciprocal
sign epistatic interactions required to create a given number of peaks.

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: Spatially explicit population genetic models have long been developed, yet
have rarely been used to test hypotheses about the spatial distribution of genetic
diversity or the genetic divergence between populations. Here, we use spatially
explicit coalescence simulations to explore the properties of the island and the
two-dimensional stepping stone models under a wide range of scenarios with spatio-temporal
variation in deme size. We avoid the simulation of genetic data, using the fact
that under the studied models, summary statistics of genetic diversity and divergence
can be approximated from coalescence times. We perform the simulations using gridCoal,
a flexible spatial wrapper for the software msprime (Kelleher et al., 2016, Theoretical
Population Biology, 95, 13) developed herein. In gridCoal, deme sizes can change
arbitrarily across space and time, as well as migration rates between individual
demes. We identify different factors that can cause a deviation from theoretical
expectations, such as the simulation time in comparison to the effective deme
size and the spatio-temporal autocorrelation across the grid. Our results highlight
that FST, a measure of the strength of population structure, principally depends
on recent demography, which makes it robust to temporal variation in deme size.
In contrast, the amount of genetic diversity is dependent on the distant past
when Ne is large, therefore longer run times are needed to estimate Ne than FST.
Finally, we illustrate the use of gridCoal on a real-world example, the range
expansion of silver fir (Abies alba Mill.) since the last glacial maximum, using
different degrees of spatio-temporal variation in deme size.

text: Maternally inherited Wolbachia transinfections are being introduced into natural
mosquito populations to reduce the transmission of dengue, Zika and other arboviruses.
Wolbachia-induced cytoplasmic incompatibility provides a frequency-dependent reproductive
advantage to infected females that can spread transinfections within and among
populations. However, because transinfections generally reduce host fitness, they
tend to spread within populations only after their frequency exceeds a critical
threshold. This produces bistability with stable equilibrium frequencies at both
0 and 1, analogous to the bistability produced by underdominance between alleles
or karyotypes and by population dynamics under Allee effects. Here, we analyze
how stochastic frequency variation produced by finite population size can facilitate
the local spread of variants with bistable dynamics into areas where invasion
is unexpected from deterministic models. Our exemplar is the establishment of
wMel Wolbachia in the Aedes aegypti population of Pyramid Estates (PE), a small
community in far north Queensland, Australia. In 2011, wMel was stably introduced
into Gordonvale, separated from PE by barriers to Ae. aegypti dispersal. After
nearly six years during which wMel was observed only at low frequencies in PE,
corresponding to an apparent equilibrium between immigration and selection, wMel
rose to fixation by 2018. Using analytic approximations and statistical analyses,
we demonstrate that the observed fixation of wMel at PE is consistent with both
stochastic transition past an unstable threshold frequency and deterministic transformation
produced by steady immigration at a rate just above the threshold required for
deterministic invasion. The indeterminacy results from a delicate balance of parameters
needed to produce the delayed transition observed. Our analyses suggest that once
Wolbachia transinfections are established locally through systematic introductions,
stochastic “threshold crossing” is likely to only minimally enhance spatial spread,
providing a local ratchet that slightly – but systematically – aids area-wide
transformation of disease-vector populations in heterogeneous landscapes.

text: When Mendel’s work was rediscovered in 1900, and extended to establish classical
genetics, it was initially seen in opposition to Darwin’s theory of evolution
by natural selection on continuous variation, as represented by the biometric
research program that was the foundation of quantitative genetics. As Fisher,
Haldane, and Wright established a century ago, Mendelian inheritance is exactly
what is needed for natural selection to work efficiently. Yet, the synthesis remains
unfinished. We do not understand why sexual reproduction and a fair meiosis predominate
in eukaryotes, or how far these are responsible for their diversity and complexity.
Moreover, although quantitative geneticists have long known that adaptive variation
is highly polygenic, and that this is essential for efficient selection, this
is only now becoming appreciated by molecular biologists—and we still do not have
a good framework for understanding polygenic variation or diffuse function.

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: 'Selection accumulates information in the genome—it guides stochastically
evolving populations toward states (genotype frequencies) that would be unlikely
under neutrality. This can be quantified as the Kullback–Leibler (KL) divergence
between the actual distribution of genotype frequencies and the corresponding
neutral distribution. First, we show that this population-level information sets
an upper bound on the information at the level of genotype and phenotype, limiting
how precisely they can be specified by selection. Next, we study how the accumulation
and maintenance of information is limited by the cost of selection, measured as
the genetic load or the relative fitness variance, both of which we connect to
the control-theoretic KL cost of control. The information accumulation rate is
upper bounded by the population size times the cost of selection. This bound is
very general, and applies across models (Wright–Fisher, Moran, diffusion) and
to arbitrary forms of selection, mutation, and recombination. Finally, the cost
of maintaining information depends on how it is encoded: Specifying a single allele
out of two is expensive, but one bit encoded among many weakly specified loci
(as in a polygenic trait) is cheap.'
