text: "The role of gene interactions in the evolutionary process has long\r\nbeen
controversial. Although some argue that they are not of\r\nimportance, because
most variation is additive, others claim that\r\ntheir effect in the long term
can be substantial. Here, we focus on\r\nthe long-term effects of genetic interactions
under directional\r\nselection assuming no mutation or dominance, and that epistasis
is\r\nsymmetrical overall. We ask by how much the mean of a complex\r\ntrait can
be increased by selection and analyze two extreme\r\nregimes, in which either
drift or selection dominate the dynamics\r\nof allele frequencies. In both scenarios,
epistatic interactions affect\r\nthe long-term response to selection by modulating
the additive\r\ngenetic variance. When drift dominates, we extend Robertson\r\n’\r\ns\r\n[Robertson
A (1960)\r\nProc R Soc Lond B Biol Sci\r\n153(951):234\r\n−\r\n249]\r\nargument
to show that, for any form of epistasis, the total response\r\nof a haploid population
is proportional to the initial total genotypic\r\nvariance. In contrast, the total
response of a diploid population is\r\nincreased by epistasis, for a given initial
genotypic variance. When\r\nselection dominates, we show that the total selection
response can\r\nonly be increased by epistasis when s\r\nome initially deleterious
alleles\r\nbecome favored as the genetic background changes. We find a sim-\r\nple
approximation for this effect and show that, in this regime, it is\r\nthe structure
of the genotype - phenotype map that matters and not\r\nthe variance components
of the population."

text: 'Selection, mutation, and random drift affect the dynamics of allele frequencies
and consequently of quantitative traits. While the macroscopic dynamics of quantitative
traits can be measured, the underlying allele frequencies are typically unobserved.
Can we understand how the macroscopic observables evolve without following these
microscopic processes? This problem has been studied previously by analogy with
statistical mechanics: the allele frequency distribution at each time point is
approximated by the stationary form, which maximizes entropy. We explore the limitations
of this method when mutation is small (4Nμ < 1) so that populations are typically
close to fixation, and we extend the theory in this regime to account for changes
in mutation strength. We consider a single diallelic locus either under directional
selection or with overdominance and then generalize to multiple unlinked biallelic
loci with unequal effects. We find that the maximum-entropy approximation is remarkably
accurate, even when mutation and selection change rapidly. '

text: The inference of demographic history from genome data is hindered by a lack
of efficient computational approaches. In particular, it has proved difficult
to exploit the information contained in the distribution of genealogies across
the genome. We have previously shown that the generating function (GF) of genealogies
can be used to analytically compute likelihoods of demographic models from configurations
of mutations in short sequence blocks (Lohse et al. 2011). Although the GF has
a simple, recursive form, the size of such likelihood calculations explodes quickly
with the number of individuals and applications of this framework have so far
been mainly limited to small samples (pairs and triplets) for which the GF can
be written by hand. Here we investigate several strategies for exploiting the
inherent symmetries of the coalescent. In particular, we show that the GF of genealogies
can be decomposed into a set of equivalence classes that allows likelihood calculations
from nontrivial samples. Using this strategy, we automated blockwise likelihood
calculations for a general set of demographic scenarios in Mathematica. These
histories may involve population size changes, continuous migration, discrete
divergence, and admixture between multiple populations. To give a concrete example,
we calculate the likelihood for a model of isolation with migration (IM), assuming
two diploid samples without phase and outgroup information. We demonstrate the
new inference scheme with an analysis of two individual butterfly genomes from
the sister species Heliconius melpomene rosina and H. cydno.

text: 'Ancestral processes are fundamental to modern population genetics and spatial
structure has been the subject of intense interest for many years. Despite this
interest, almost nothing is known about the distribution of the locations of pedigree
or genetic ancestors. Using both spatially continuous and stepping-stone models,
we show that the distribution of pedigree ancestors approaches a travelling wave,
for which we develop two alternative approximations. The speed and width of the
wave are sensitive to the local details of the model. After a short time, genetic
ancestors spread far more slowly than pedigree ancestors, ultimately diffusing
out with radius ## rather than spreading at constant speed. In contrast to the
wave of pedigree ancestors, the spread of genetic ancestry is insensitive to the
local details of the models.'

text: Speciation results from the progressive accumulation of mutations that decrease
the probability of mating between parental populations or reduce the fitness of
hybrids—the so-called species barriers. The speciation genomic literature, however,
is mainly a collection of case studies, each with its own approach and specificities,
such that a global view of the gradual process of evolution from one to two species
is currently lacking. Of primary importance is the prevalence of gene flow between
diverging entities, which is central in most species concepts and has been widely
discussed in recent years. Here, we explore the continuum of speciation thanks
to a comparative analysis of genomic data from 61 pairs of populations/species
of animals with variable levels of divergence. Gene flow between diverging gene
pools is assessed under an approximate Bayesian computation (ABC) framework. We
show that the intermediate "grey zone" of speciation, in which taxonomy
is often controversial, spans from 0.5% to 2% of net synonymous divergence, irrespective
of species life history traits or ecology. Thanks to appropriate modeling of among-locus
variation in genetic drift and introgression rate, we clarify the status of the
majority of ambiguous cases and uncover a number of cryptic species. Our analysis
also reveals the high incidence in animals of semi-isolated species (when some
but not all loci are affected by barriers to gene flow) and highlights the intrinsic
difficulty, both statistical and conceptual, of delineating species in the grey
zone of speciation.

text: "Natural environments are never constant but subject to spatial and temporal
change on\r\nall scales, increasingly so due to human activity. Hence, it is crucial
to understand the\r\nimpact of environmental variation on evolutionary processes.
In this thesis, I present\r\nthree topics that share the common theme of environmental
variation, yet illustrate its\r\neffect from different perspectives.\r\nFirst,
I show how a temporally fluctuating environment gives rise to second-order\r\nselection
on a modifier for stress-induced mutagenesis. Without fluctuations, when\r\npopulations
are adapted to their environment, mutation rates are minimized. I argue\r\nthat
a stress-induced mutator mechanism may only be maintained if the population is\r\nrepeatedly
subjected to diverse environmental challenges, and I outline implications of\r\nthe
presented results to antibiotic treatment strategies.\r\nSecond, I discuss my
work on the evolution of dispersal. Besides reproducing\r\nknown results about
the effect of heterogeneous habitats on dispersal, it identifies\r\nspatial changes
in dispersal type frequencies as a source for selection for increased\r\npropensities
to disperse. This concept contains effects of relatedness that are known\r\nto
promote dispersal, and I explain how it identifies other forces selecting for
dispersal\r\nand puts them on a common scale.\r\nThird, I analyse genetic variances
of phenotypic traits under multivariate stabilizing\r\nselection. For the case
of constant environments, I generalize known formulae of\r\nequilibrium variances
to multiple traits and discuss how the genetic variance of a focal\r\ntrait is
influenced by selection on background traits. I conclude by presenting ideas and\r\npreliminary
work aiming at including environmental fluctuations in the form of moving\r\ntrait
optima into the model."

text: 'Gene regulation relies on the specificity of transcription factor (TF)–DNA
interactions. Limited specificity may lead to crosstalk: a regulatory state in
which a gene is either incorrectly activated due to noncognate TF–DNA interactions
or remains erroneously inactive. As each TF can have numerous interactions with
noncognate cis-regulatory elements, crosstalk is inherently a global problem,
yet has previously not been studied as such. We construct a theoretical framework
to analyse the effects of global crosstalk on gene regulation. We find that crosstalk
presents a significant challenge for organisms with low-specificity TFs, such
as metazoans. Crosstalk is not easily mitigated by known regulatory schemes acting
at equilibrium, including variants of cooperativity and combinatorial regulation.
Our results suggest that crosstalk imposes a previously unexplored global constraint
on the functioning and evolution of regulatory networks, which is qualitatively
distinct from the known constraints that act at the level of individual gene regulatory
elements.'

text: Much of quantitative genetics is based on the ‘infinitesimal model’, under
which selection has a negligible effect on the genetic variance. This is typically
justified by assuming a very large number of loci with additive effects. However,
it applies even when genes interact, provided that the number of loci is large
enough that selection on each of them is weak relative to random drift. In the
long term, directional selection will change allele frequencies, but even then,
the effects of epistasis on the ultimate change in trait mean due to selection
may be modest. Stabilising selection can maintain many traits close to their optima,
even when the underlying alleles are weakly selected. However, the number of traits
that can be optimised is apparently limited to ~4Ne by the ‘drift load’, and this
is hard to reconcile with the apparent complexity of many organisms. Just as for
the mutation load, this limit can be evaded by a particular form of negative epistasis.
A more robust limit is set by the variance in reproductive success. This suggests
that selection accumulates information most efficiently in the infinitesimal regime,
when selection on individual alleles is weak, and comparable with random drift.
A review of evidence on selection strength suggests that although most variance
in fitness may be because of alleles with large Nes, substantial amounts of adaptation
may be because of alleles in the infinitesimal regime, in which epistasis has
modest effects.

text: Viral capsids are structurally constrained by interactions among the amino
acids (AAs) of their constituent proteins. Therefore, epistasis is expected to
evolve among physically interacting sites and to influence the rates of substitution.
To study the evolution of epistasis, we focused on the major structural protein
of the ϕX174 phage family by, first, reconstructing the ancestral protein sequences
of 18 species using a Bayesian statistical framework. The inferred ancestral reconstruction
differed at eight AAs, for a total of 256 possible ancestral haplotypes. For each
ancestral haplotype and the extant species, we estimated, in silico, the distribution
of free energies and epistasis of the capsid structure. We found that free energy
has not significantly increased but epistasis has. We decomposed epistasis up
to fifth order and found that higher-order epistasis sometimes compensates pairwise
interactions making the free energy seem additive. The dN/dS ratio is low, suggesting
strong purifying selection, and that structure is under stabilizing selection.
We synthesized phages carrying ancestral haplotypes of the coat protein gene and
measured their fitness experimentally. Our findings indicate that stabilizing
mutations can have higher fitness, and that fitness optima do not necessarily
coincide with energy minima.

text: Background and aims Angiosperms display remarkable diversity in flower colour,
implying that transitions between pigmentation phenotypes must have been common.
Despite progress in understanding transitions between anthocyanin (blue, purple,
pink or red) and unpigmented (white) flowers, little is known about the evolutionary
patterns of flower-colour transitions in lineages with both yellow and anthocyanin-pigmented
flowers. This study investigates the relative rates of evolutionary transitions
between different combinations of yellow- and anthocyanin-pigmentation phenotypes
in the tribe Antirrhineae. Methods We surveyed taxonomic literature for data on
anthocyanin and yellow floral pigmentation for 369 species across the tribe. We
then reconstructed the phylogeny of 169 taxa and used phylogenetic comparative
methods to estimate transition rates among pigmentation phenotypes across the
phylogeny. Key Results In contrast to previous studies we found a bias towards
transitions involving a gain in pigmentation, although transitions to phenotypes
with both anthocyanin and yellow taxa are nevertheless extremely rare. Despite
the dominance of yellow and anthocyanin-pigmented taxa, transitions between these
phenotypes are constrained to move through a white intermediate stage, whereas
transitions to double-pigmentation are very rare. The most abundant transitions
are between anthocyanin-pigmented and unpigmented flowers, and similarly the most
abundant polymorphic taxa were those with anthocyanin-pigmented and unpigmented
flowers. Conclusions Our findings show that pigment evolution is limited by the
presence of other floral pigments. This interaction between anthocyanin and yellow
pigments constrains the breadth of potential floral diversity observed in nature.
In particular, they suggest that selection has repeatedly acted to promote the
spread of single-pigmented phenotypes across the Antirrhineae phylogeny. Furthermore,
the correlation between transition rates and polymorphism suggests that the forces
causing and maintaining variance in the short term reflect evolutionary processes
on longer time scales.

text: Hybrid zones represent evolutionary laboratories, where recombination brings
together alleles in combinations which have not previously been tested by selection.
This provides an excellent opportunity to test the effect of molecular variation
on fitness, and how this variation is able to spread through populations in a
natural context. The snapdragon Antirrhinum majus is polymorphic in the wild for
two loci controlling the distribution of yellow and magenta floral pigments. Where
the yellow A. m. striatum and the magenta A. m. pseudomajus meet along a valley
in the Spanish Pyrenees they form a stable hybrid zone Alleles at these loci recombine
to give striking transgressive variation for flower colour. The sharp transition
in phenotype over ~1km implies strong selection maintaining the hybrid zone. An
indirect assay of pollinator visitation in the field found that pollinators forage
in a positive-frequency dependent manner on Antirrhinum, matching previous data
on fruit set. Experimental arrays and paternity analysis of wild-pollinated seeds
demonstrated assortative mating for pigmentation alleles, and that pollinator
behaviour alone is sufficient to explain this pattern. Selection by pollinators
should be sufficiently strong to maintain the hybrid zone, although other mechanisms
may be at work. At a broader scale I examined evolutionary transitions between
yellow and anthocyanin pigmentation in the tribe Antirrhinae, and found that selection
has acted strate that pollinators are a major determinant of reproductive success
and mating patterns in wild Antirrhinum.

to Jon Ågren for his patience whilst I finished this thesis, and to Sylvia Cremer
and Magnus Nordborg for taking the time to read and evaluate the thesis given a
shorter deadline than was fair. \r\n\r\nA very positive aspect of my PhD has been
the supportive atmosphere of IST. In particular, I have come to appreciate the enormous
support from our group assistants Nicole Hotzy, Julia Asimakis, Christine Ostermann
and Jerneja Beslagic. I also thank Christian Chaloupka and Stefan Hipfinger for
their enthusiasm and readiness to help where possible in setting up our greenhouse
and experiments. "

text: "Evolution of gene regulation is important for phenotypic evolution and diversity.
Sequence-specific binding of regulatory proteins is one of the key regulatory
mechanisms determining gene expression. Although there has been intense interest
in evolution of regulatory binding sites in the last decades, a theoretical understanding
is far from being complete. In this thesis, I aim at a better understanding of
the evolution of transcriptional regulatory binding sequences by using biophysical
and population genetic models.\r\nIn the first part of the thesis, I discuss how
to formulate the evolutionary dynamics of binding se- quences in a single isolated
binding site and in promoter/enhancer regions. I develop a theoretical framework
bridging between a thermodynamical model for transcription and a mutation-selection-drift
model for monomorphic populations. I mainly address the typical evolutionary rates,
and how they de- pend on biophysical parameters (e.g. binding length and specificity)
and population genetic parameters (e.g. population size and selection strength).\r\nIn
the second part of the thesis, I analyse empirical data for a better evolutionary
and biophysical understanding of sequence-specific binding of bacterial RNA polymerase.
First, I infer selection on regulatory and non-regulatory binding sites of RNA
polymerase in the E. coli K12 genome. Second, I infer the chemical potential of
RNA polymerase, an important but unknown physical parameter defining the threshold
energy for strong binding. Furthermore, I try to understand the relation between
the lac promoter sequence diversity and the LacZ activity variation among 20 bacterial
isolates by constructing a simple but biophysically motivated gene expression
model. Lastly, I lay out a statistical framework to predict adaptive point mutations
in de novo promoter evolution in a selection experiment."
acknowledgement: This PhD thesis may not have been completed without the help and
care I received from some peo- ple during my PhD life. I am especially grateful
to Tiago Paixao, Gasper Tkacik, Nick Barton, not only for their scientific advices
but also for their patience and support. I thank Calin Guet and Jonathan Bollback
for allowing me to “play around” in their labs and get some experience on experimental
evolution. I thank Magdalena Steinrueck and Fabienne Jesse for collaborating and
sharing their experimental data with me. I thank Johannes Jaeger for reviewing my
thesis. I thank all members of Barton group (aka bartonians) for their feedback,
and all workers of IST Austria for making the best working conditions. Lastly, I
thank two special women, Nejla Sag ̆lam and Setenay Dog ̆an, for their continuous
support and encouragement. I truly had a great chance of having right people around
me.

text: "Data from array experiments investigating pollinator behaviour on snapdragons
in controlled conditions, and their effect on plant mating. Data were collected
as part of Tom Ellis' PhD thesis , submitted February 2016.\r\n\r\nWe placed a
total of 36 plants in a grid inside a closed organza tent, with a single hive
of commercially bred bumblebees (Bombus hortorum). We used only the yellow-flowered
Antirrhinum majus striatum and the magenta-flowered Antirrhinum majus pseudomajus,
at ratios of 6:36, 12:24, 18:18, 24:12 and 30:6.\r\n\r\nAfter 24 hours to learn
how to deal with snapdragons, I observed pollinators foraging on plants, and recorded
the transitions between plants. Thereafter seeds on plants were allowed to develops.
A sample of these were grown to maturity when their flower colour could be determined,
and they were scored as yellow, magenta, or hybrid."
