text: "Gene Drives are regarded as future tools with a high potential for population
control. Due to their inherent ability to overcome the rules of Mendelian inheritance,
gene drives (GD) may spread genes rapidly through populations of sexually reproducing
organisms. A release of organisms carrying a GD would constitute a paradigm shift
in the handling of genetically modified organisms because gene drive organisms
(GDO) are designed to drive their transgenes into wild populations and thereby
increase the number of GDOs. The rapid development in this field and its focus
on wild populations demand a prospective risk assessment with a focus on exposure
related aspects. Presently, it is unclear how adequate risk management could be
guaranteed to limit the spread of GDs in time and space, in order to avoid potential
adverse effects in socio‐ecological systems.\r\n\r\nThe recent workshop on the
“Evaluation of Spatial and Temporal Control of Gene Drives” hosted by the Institute
of Safety/Security and Risk Sciences (ISR) in Vienna aimed at gaining some insight
into the potential population dynamic behavior of GDs and appropriate measures
of control. Scientists from France, Germany, England, and the USA discussed both
topics in this meeting on April 4–5, 2019. This article summarizes results of
the workshop."

text: The study of parallel ecological divergence provides important clues to the
operation of natural selection. Parallel divergence often occurs in heterogeneous
environments with different kinds of environmental gradients in different locations,
but the genomic basis underlying this process is unknown. We investigated the
genomics of rapid parallel adaptation in the marine snail Littorina saxatilis
in response to two independent environmental axes (crab-predation versus wave-action
and low-shore versus high-shore). Using pooled whole-genome resequencing, we show
that sharing of genomic regions of high differentiation between environments is
generally low but increases at smaller spatial scales. We identify different shared
genomic regions of divergence for each environmental axis and show that most of
these regions overlap with candidate chromosomal inversions. Several inversion
regions are divergent and polymorphic across many localities. We argue that chromosomal
inversions could store shared variation that fuels rapid parallel adaptation to
heterogeneous environments, possibly as balanced polymorphism shared by adaptive
gene flow.

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: 'Plant mating systems play a key role in structuring genetic variation both
within and between species. In hybrid zones, the outcomes and dynamics of hybridization
are usually interpreted as the balance between gene flow and selection against
hybrids. Yet, mating systems can introduce selective forces that alter these expectations;
with diverse outcomes for the level and direction of gene flow depending on variation
in outcrossing and whether the mating systems of the species pair are the same
or divergent. We present a survey of hybridization in 133 species pairs from 41
plant families and examine how patterns of hybridization vary with mating system.
We examine if hybrid zone mode, level of gene flow, asymmetries in gene flow and
the frequency of reproductive isolating barriers vary in relation to mating system/s
of the species pair. We combine these results with a simulation model and examples
from the literature to address two general themes: (i) the two‐way interaction
between introgression and the evolution of reproductive systems, and (ii) how
mating system can facilitate or restrict interspecific gene flow. We conclude
that examining mating system with hybridization provides unique opportunities
to understand divergence and the processes underlying reproductive isolation.'

text: Evolutionary studies are often limited by missing data that are critical to
understanding the history of selection. Selection experiments, which reproduce
rapid evolution under controlled conditions, are excellent tools to study how
genomes evolve under selection. Here we present a genomic dissection of the Longshanks
selection experiment, in which mice were selectively bred over 20 generations
for longer tibiae relative to body mass, resulting in 13% longer tibiae in two
replicates. We synthesized evolutionary theory, genome sequences and molecular
genetics to understand the selection response and found that it involved both
polygenic adaptation and discrete loci of major effect, with the strongest loci
tending to be selected in parallel between replicates. We show that selection
may favor de-repression of bone growth through inactivating two limb enhancers
of an inhibitor, Nkx3-2. Our integrative genomic analyses thus show that it is
possible to connect individual base-pair changes to the overall selection response.

text: Adaptive introgression is common in nature and can be driven by selection
acting on multiple, linked genes. We explore the effects of polygenic selection
on introgression under the infinitesimal model with linkage. This model assumes
that the introgressing block has an effectively infinite number of genes, each
with an infinitesimal effect on the trait under selection. The block is assumed
to introgress under directional selection within a native population that is genetically
homogeneous. We use individual-based simulations and a branching process approximation
to compute various statistics of the introgressing block, and explore how these
depend on parameters such as the map length and initial trait value associated
with the introgressing block, the genetic variability along the block, and the
strength of selection. Our results show that the introgression dynamics of a block
under infinitesimal selection is qualitatively different from the dynamics of
neutral introgression. We also find that in the long run, surviving descendant
blocks are likely to have intermediate lengths, and clarify how the length is
shaped by the interplay between linkage and infinitesimal selection. Our results
suggest that it may be difficult to distinguish introgression of single loci from
that of genomic blocks with multiple, tightly linked and weakly selected loci.

text: 'Pedigree and sibship reconstruction are important methods in quantifying
relationships and fitness of individuals in natural populations. Current methods
employ a Markov chain-based algorithm to explore plausible possible pedigrees
iteratively. This provides accurate results, but is time-consuming. Here, we develop
a method to infer sibship and paternity relationships from half-sibling arrays
of known maternity using hierarchical clustering. Given 50 or more unlinked SNP
markers and empirically derived error rates, the method performs as well as the
widely used package Colony, but is faster by two orders of magnitude. Using simulations,
we show that the method performs well across contrasting mating scenarios, even
when samples are large. We then apply the method to open-pollinated arrays of
the snapdragon Antirrhinum majus and find evidence for a high degree of multiple
mating. Although we focus on diploid SNP data, the method does not depend on marker
type and as such has broad applications in nonmodel systems. '

text: 'Genome-scale diversity data are increasingly available in a variety of biological
systems, and can be used to reconstruct the past evolutionary history of species
divergence. However, extracting the full demographic information from these data
is not trivial, and requires inferential methods that account for the diversity
of coalescent histories throughout the genome. Here, we evaluate the potential
and limitations of one such approach. We reexamine a well-known system of mussel
sister species, using the joint site frequency spectrum (jSFS) of synonymousmutations
computed either fromexome capture or RNA-seq, in an Approximate Bayesian Computation
(ABC) framework. We first assess the best sampling strategy (number of: individuals,
loci, and bins in the jSFS), and show that model selection is robust to variation
in the number of individuals and loci. In contrast, different binning choices
when summarizing the jSFS, strongly affect the results: including classes of low
and high frequency shared polymorphisms can more effectively reveal recent migration
events. We then take advantage of the flexibility of ABC to compare more realistic
models of speciation, including variation in migration rates through time (i.e.,
periodic connectivity) and across genes (i.e., genome-wide heterogeneity in migration
rates). We show that these models were consistently selected as the most probable,
suggesting that mussels have experienced a complex history of gene flow during
divergence and that the species boundary is semi-permeable. Our work provides
a comprehensive evaluation of ABC demographic inference in mussels based on the
coding jSFS, and supplies guidelines for employing different sequencing techniques
and sampling strategies. We emphasize, perhaps surprisingly, that inferences are
less limited by the volume of data, than by the way in which they are analyzed.'

text: "In continuous populations with local migration, nearby pairs of individuals
have on average more similar genotypes\r\nthan geographically well separated pairs.
A barrier to gene flow distorts this classical pattern of isolation by distance.
Genetic similarity is decreased for sample pairs on different sides of the barrier
and increased for pairs on the same side near the barrier. Here, we introduce
an inference scheme that utilizes this signal to detect and estimate the strength
of a linear barrier to gene flow in two-dimensions. We use a diffusion approximation
to model the effects of a barrier on the geographical spread of ancestry backwards
in time. This approach allows us to calculate the chance of recent coalescence
and probability of identity by descent. We introduce an inference scheme that
fits these theoretical results to the geographical covariance structure of bialleleic
genetic markers. It can estimate the strength of the barrier as well as several
demographic parameters. We investigate the power of our inference scheme to detect
barriers by applying it to a wide range of simulated data. We also showcase an
example application to a Antirrhinum majus (snapdragon) flower color hybrid zone,
where we do not detect any signal of a strong genome wide barrier to gene flow."

text: "Maladapted individuals can only colonise a new habitat if they can evolve
a\r\npositive growth rate fast enough to avoid extinction, a process known as
evolutionary\r\nrescue. We treat log fitness at low density in the new habitat
as a\r\nsingle polygenic trait and thus use the infinitesimal model to follow
the evolution\r\nof the growth rate; this assumes that the trait values of offspring
of a\r\nsexual union are normally distributed around the mean of the parents’
trait\r\nvalues, with variance that depends only on the parents’ relatedness.
The\r\nprobability that a single migrant can establish depends on just two parameters:\r\nthe
mean and genetic variance of the trait in the source population.\r\nThe chance
of success becomes small if migrants come from a population\r\nwith mean growth
rate in the new habitat more than a few standard deviations\r\nbelow zero; this
chance depends roughly equally on the probability\r\nthat the initial founder
is unusually fit, and on the subsequent increase in\r\ngrowth rate of its offspring
as a result of selection. The loss of genetic variation\r\nduring the founding
event is substantial, but highly variable. With\r\ncontinued migration at rate
M, establishment is inevitable; when migration\r\nis rare, the expected time to
establishment decreases inversely with M.\r\nHowever, above a threshold migration
rate, the population may be trapped\r\nin a ‘sink’ state, in which adaptation
is held back by gene flow; above this\r\nthreshold, the expected time to establishment
increases exponentially with M. This threshold behaviour is captured by a deterministic
approximation,\r\nwhich assumes a Gaussian distribution of the trait in the founder
population\r\nwith mean and variance evolving deterministically. By assuming a
constant\r\ngenetic variance, we also develop a diffusion approximation for the
joint distribution\r\nof population size and trait mean, which extends to include
stabilising\r\nselection and density regulation. Divergence of the population
from its\r\nancestors causes partial reproductive isolation, which we measure
through\r\nthe reproductive value of migrants into the newly established population."

text: 'We re-examine the model of Kirkpatrick and Barton for the spread of an inversion
into a local population. This model assumes that local selection maintains alleles
at two or more loci, despite immigration of alternative alleles at these loci
from another population. We show that an inversion is favored because it prevents
the breakdown of linkage disequilibrium generated by migration; the selective
advantage of an inversion is proportional to the amount of recombination between
the loci involved, as in other cases where inversions are selected for. We derive
expressions for the rate of spread of an inversion; when the loci covered by the
inversion are tightly linked, these conditions deviate substantially from those
proposed previously, and imply that an inversion can then have only a small advantage. '

text: We study the Fokker-Planck equation derived in the large system limit of the
Markovian process describing the dynamics of quantitative traits. The Fokker-Planck
equation is posed on a bounded domain and its transport and diffusion coefficients
vanish on the domain's boundary. We first argue that, despite this degeneracy,
the standard no-flux boundary condition is valid. We derive the weak formulation
of the problem and prove the existence and uniqueness of its solutions by constructing
the corresponding contraction semigroup on a suitable function space. Then, we
prove that for the parameter regime with high enough mutation rate the problem
exhibits a positive spectral gap, which implies exponential convergence to equilibrium.Next,
we provide a simple derivation of the so-called Dynamic Maximum Entropy (DynMaxEnt)
method for approximation of observables (moments) of the Fokker-Planck solution,
which can be interpreted as a nonlinear Galerkin approximation. The limited applicability
of the DynMaxEnt method inspires us to introduce its modified version that is
valid for the whole range of admissible parameters. Finally, we present several
numerical experiments to demonstrate the performance of both the original and
modified DynMaxEnt methods. We observe that in the parameter regimes where both
methods are valid, the modified one exhibits slightly better approximation properties
compared to the original one.

text: This thesis is concerned with the inference of current population structure
based on geo-referenced genetic data. The underlying idea is that population structure
affects its spatial genetic structure. Therefore, genotype information can be
utilized to estimate important demographic parameters such as migration rates.
These indirect estimates of population structure have become very attractive,
as genotype data is now widely available. However, there also has been much concern
about these approaches. Importantly, genetic structure can be influenced by many
complex patterns, which often cannot be disentangled. Moreover, many methods merely
fit heuristic patterns of genetic structure, and do not build upon population
genetics theory. Here, I describe two novel inference methods that address these
shortcomings. In Chapter 2, I introduce an inference scheme based on a new type
of signal, identity by descent (IBD) blocks. Recently, it has become feasible
to detect such long blocks of genome shared between pairs of samples. These blocks
are direct traces of recent coalescence events. As such, they contain ample signal
for inferring recent demography. I examine sharing of IBD blocks in two-dimensional
populations with local migration. Using a diffusion approximation, I derive formulas
for an isolation by distance pattern of long IBD blocks and show that sharing
of long IBD blocks approaches rapid exponential decay for growing sample distance.
I describe an inference scheme based on these results. It can robustly estimate
the dispersal rate and population density, which is demonstrated on simulated
data. I also show an application to estimate mean migration and the rate of recent
population growth within Eastern Europe. Chapter 3 is about a novel method to
estimate barriers to gene flow in a two dimensional population. This inference
scheme utilizes geographically localized allele frequency fluctuations - a classical
isolation by distance signal. The strength of these local fluctuations increases
on average next to a barrier, and there is less correlation across it. I again
use a framework of diffusion of ancestral lineages to model this effect, and provide
an efficient numerical implementation to fit the results to geo-referenced biallelic
SNP data. This inference scheme is able to robustly estimate strong barriers to
gene flow, as tests on simulated data confirm.

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.

text: Herd immunity, a process in which resistant individuals limit the spread of
a pathogen among susceptible hosts has been extensively studied in eukaryotes.
Even though bacteria have evolved multiple immune systems against their phage
pathogens, herd immunity in bacteria remains unexplored. Here we experimentally
demonstrate that herd immunity arises during phage epidemics in structured and
unstructured Escherichia coli populations consisting of differing frequencies
of susceptible and resistant cells harboring CRISPR immunity. In addition, we
develop a mathematical model that quantifies how herd immunity is affected by
spatial population structure, bacterial growth rate, and phage replication rate.
Using our model we infer a general epidemiological rule describing the relative
speed of an epidemic in partially resistant spatially structured populations.
Our experimental and theoretical findings indicate that herd immunity may be important
in bacterial communities, allowing for stable coexistence of bacteria and their
phages and the maintenance of polymorphism in bacterial immunity.

text: Escaping local optima is one of the major obstacles to function optimisation.
Using the metaphor of a fitness landscape, local optima correspond to hills separated
by fitness valleys that have to be overcome. We define a class of fitness valleys
of tunable difficulty by considering their length, representing the Hamming path
between the two optima and their depth, the drop in fitness. For this function
class we present a runtime comparison between stochastic search algorithms using
different search strategies. The (1+1) EA is a simple and well-studied evolutionary
algorithm that has to jump across the valley to a point of higher fitness because
it does not accept worsening moves (elitism). In contrast, the Metropolis algorithm
and the Strong Selection Weak Mutation (SSWM) algorithm, a famous process in population
genetics, are both able to cross the fitness valley by accepting worsening moves.
We show that the runtime of the (1+1) EA depends critically on the length of the
valley while the runtimes of the non-elitist algorithms depend crucially on the
depth of the valley. Moreover, we show that both SSWM and Metropolis can also
efficiently optimise a rugged function consisting of consecutive valleys.
