  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: 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: '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 &lt; 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: 'How likely is it that a population escapes extinction through adaptive evolution?
    The answer to this question is of great relevance in conservation biology, where
    we aim at species’ rescue and the maintenance of biodiversity, and in agriculture
    and medicine, where we seek to hamper the emergence of pesticide or drug resistance.
    By reshuffling the genome, recombination has two antagonistic effects on the probability
    of evolutionary rescue: It generates and it breaks up favorable gene combinations.
    Which of the two effects prevails depends on the fitness effects of mutations
    and on the impact of stochasticity on the allele frequencies. In this article,
    we analyze a mathematical model for rescue after a sudden environmental change
    when adaptation is contingent on mutations at two loci. The analysis reveals a
    complex nonlinear dependence of population survival on recombination. We moreover
    find that, counterintuitively, a fast eradication of the wild type can promote
    rescue in the presence of recombination. The model also shows that two-step rescue
    is not unlikely to happen and can even be more likely than single-step rescue
    (where adaptation relies on a single mutation), depending on the circumstances.'

  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: 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: '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: 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.
acknowledgement: "I am indebted to many people for their support during my PhD, but
  I particularly wish to thank Nick Barton for his guidance and intuition, and for
  encouraging me to take the time to look beyond the immediate topic of my PhD to
  understand the broader context. I am also especially grateful to David Field his
  bottomless patience, invaluable advice on experimental design, analysis and scientific
  writing, and for tireless work on the population surveys and genomic work without
  most of my thesis could not have happened. \r\n\r\nIt has been a pleasure to work
  with the combined strengths of the groups at The John Innes Centre, University of
  Toulouse and IST Austria. Thanks to Enrico Coen and his group for hosting me in
  Norwich in 2011 and especially for setting up the tag experiment. \r\n\r\nI thank
  David Field, Desmond Bradley and Maria Clara Melo-Hurtado for organising field collections,
  as well as Monique Burrus and Christophe Andalo and a large number of volunteers
  for their e ff orts helping with the field work. Furthermore I thank Coline Jaworski
  for providing seeds and for her input into the design of the experimental arrays,
  and Matthew Couchman for maintaining the database of. \r\n\r\nIn addition to those
  mentioned above, I am grateful to Melinda Pickup, Spencer Barrett, and four anonymous
  reviewers for their insightful comments on sections of this manuscript. I also thank
  Jana Porsche for her e ff orts in tracking down the more obscure references for
  chapter 5, and Jon Bollback for his advice about the analysis. \r\n\r\nI am indebted
  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. "

    flowers have a mouth-like structure which pollinators must open to access nectar.
    We placed 5mm cellophane tags in these mouths, which are held in place by the
    pressure of the flower until a pollinator visits. When she opens the flower, the
    tag drops out, and one can infer a visit. We surveyed plants over multiple days
    in 2010, 2011 and 2012.\r\n\r\nAlso included are data on phenotypic and demographic
    variables which may be explanatory variables for pollinator visitation."

  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.
