text: Fitness interactions between mutations can influence a population’s evolution
in many different ways. While epistatic effects are difficult to measure precisely,
important information is captured by the mean and variance of log fitnesses for
individuals carrying different numbers of mutations. We derive predictions for
these quantities from a class of simple fitness landscapes, based on models of
optimizing selection on quantitative traits. We also explore extensions to the
models, including modular pleiotropy, variable effect sizes, mutational bias and
maladaptation of the wild type. We illustrate our approach by reanalysing a large
dataset of mutant effects in a yeast snoRNA. Though characterized by some large
epistatic effects, these data give a good overall fit to the non-epistatic null
model, suggesting that epistasis might have limited influence on the evolutionary
dynamics in this system. We also show how the amount of epistasis depends on both
the underlying fitness landscape and the distribution of mutations, and so is
expected to vary in consistent ways between new mutations, standing variation
and fixed mutations.

text: Genetic incompatibilities contribute to reproductive isolation between many
diverging populations, but it is still unclear to what extent they play a role
if divergence happens with gene flow. In contact zones between the "Crab" and
"Wave" ecotypes of the snail Littorina saxatilis, divergent selection forms strong
barriers to gene flow, while the role of post‐zygotic barriers due to selection
against hybrids remains unclear. High embryo abortion rates in this species could
indicate the presence of such barriers. Post‐zygotic barriers might include genetic
incompatibilities (e.g. Dobzhansky–Muller incompatibilities) but also maladaptation,
both expected to be most pronounced in contact zones. In addition, embryo abortion
might reflect physiological stress on females and embryos independent of any genetic
stress. We examined all embryos of >500 females sampled outside and inside contact
zones of three populations in Sweden. Females' clutch size ranged from 0 to 1,011
embryos (mean 130 ± 123), and abortion rates varied between 0% and 100% (mean
12%). We described female genotypes by using a hybrid index based on hundreds
of SNPs differentiated between ecotypes with which we characterized female genotypes.
We also calculated female SNP heterozygosity and inversion karyotype. Clutch size
did not vary with female hybrid index, and abortion rates were only weakly related
to hybrid index in two sites but not at all in a third site. No additional variation
in abortion rate was explained by female SNP heterozygosity, but increased female
inversion heterozygosity added slightly to increased abortion. Our results show
only weak and probably biologically insignificant post‐zygotic barriers contributing
to ecotype divergence, and the high and variable abortion rates were marginally,
if at all, explained by hybrid index of females.

text: The biotic interactions hypothesis posits that biotic interactions are more
important drivers of adaptation closer to the equator, evidenced by “stronger”
contemporary interactions (e.g. greater interaction rates) and/or patterns of
trait evolution consistent with a history of stronger interactions. Support for
the hypothesis is mixed, but few studies span tropical and temperate regions while
experimentally controlling for evolutionary history. Here, we integrate field
observations and common garden experiments to quantify the relative importance
of pollination and herbivory in a pair of tropical‐temperate congeneric perennial
herbs. Phytolacca rivinoides and P. americana are pioneer species native to the
Neotropics and the eastern USA, respectively. We compared plant‐pollinator and
plant‐herbivore interactions between three tropical populations of P. rivinoides
from Costa Rica and three temperate populations of P. americana from its northern
range edge in Michigan and Ohio. For some metrics of interaction importance, we
also included three subtropical populations of P. americana from its southern
range edge in Florida. This approach confounds species and region but allows us,
uniquely, to measure complementary proxies of interaction importance across a
tropical‐temperate range in one system. To test the prediction that lower‐latitude
plants are more reliant on insect pollinators, we quantified floral display and
reward, insect visitation rates, and self‐pollination ability (autogamy). To test
the prediction that lower‐latitude plants experience more herbivore pressure,
we quantified herbivory rates, herbivore abundance, and leaf palatability. We
found evidence supporting the biotic interactions hypothesis for most comparisons
between P. rivinoides and north‐temperate P. americana (floral display, insect
visitation, autogamy, herbivory, herbivore abundance, and young‐leaf palatability).
Results for subtropical P. americana populations, however, were typically not
intermediate between P. rivinoides and north‐temperate P. americana, as would
be predicted by a linear latitudinal gradient in interaction importance. Subtropical
young‐leaf palatability was intermediate, but subtropical mature leaves were the
least palatable, and pollination‐related traits did not differ between temperate
and subtropical regions. These nonlinear patterns of interaction importance suggest
future work to relate interaction importance to climatic or biotic thresholds.
In sum, we found that the biotic interactions hypothesis was more consistently
supported at the larger spatial scale of our study.

text: The growth of snail shells can be described by simple mathematical rules.
Variation in a few parameters can explain much of the diversity of shell shapes
seen in nature. However, empirical studies of gastropod shell shape variation
typically use geometric morphometric approaches, which do not capture this growth
pattern. We have developed a way to infer a set of developmentally descriptive
shape parameters based on three-dimensional logarithmic helicospiral growth and
using landmarks from two-dimensional shell images as input. We demonstrate the
utility of this approach, and compare it to the geometric morphometric approach,
using a large set of Littorina saxatilis shells in which locally adapted populations
differ in shape. Our method can be modified easily to make it applicable to a
wide range of shell forms, which would allow for investigations of the similarities
and differences between and within many different species of gastropods.

text: Empirical data suggest that inversions in many species contain genes important
for intraspecific divergence and speciation, yet mechanisms of evolution remain
unclear. While genes inside an inversion are tightly linked, inversions are not
static but evolve separately from the rest of the genome by new mutations, recombination
within arrangements, and gene flux between arrangements. Inversion polymorphisms
are maintained by different processes, for example, divergent or balancing selection,
or a mix of multiple processes. Moreover, the relative roles of selection, drift,
mutation, and recombination will change over the lifetime of an inversion and
within its area of distribution. We believe inversions are central to the evolution
of many species, but we need many more data and new models to understand the complex
mechanisms involved.

text: The evolution of new species is made easier when traits under divergent ecological
selection are also mating cues. Such ecological mating cues are now considered
more common than previously thought, but we still know little about the genetic
changes underlying their evolution or more generally about the genetic basis for
assortative mating behaviors. Both tight physical linkage and the existence of
large-effect preference loci will strengthen genetic associations between behavioral
and ecological barriers, promoting the evolution of assortative mating. The warning
patterns of Heliconius melpomene and H. cydno are under disruptive selection due
to increased predation of nonmimetic hybrids and are used during mate recognition.
We carried out a genome-wide quantitative trait locus (QTL) analysis of preference
behaviors between these species and showed that divergent male preference has
a simple genetic basis. We identify three QTLs that together explain a large proportion
(approximately 60%) of the difference in preference behavior observed between
the parental species. One of these QTLs is just 1.2 (0-4.8) centiMorgans (cM)
from the major color pattern gene optix, and, individually, all three have a large
effect on the preference phenotype. Genomic divergence between H. cydno and H.
melpomene is high but broadly heterogenous, and admixture is reduced at the preference-optix
color pattern locus but not the other preference QTLs. The simple genetic architecture
we reveal will facilitate the evolution and maintenance of new species despite
ongoing gene flow by coupling behavioral and ecological aspects of reproductive
isolation.

text: 'Transcription factors, by binding to specific sequences on the DNA, control
the precise spatio-temporal expression of genes inside a cell. However, this specificity
is limited, leading to frequent incorrect binding of transcription factors that
might have deleterious consequences on the cell. By constructing a biophysical
model of TF-DNA binding in the context of gene regulation, I will first explore
how regulatory constraints can strongly shape the distribution of a population
in sequence space. Then, by directly linking this to a picture of multiple types
of transcription factors performing their functions simultaneously inside the
cell, I will explore the extent of regulatory crosstalk -- incorrect binding interactions
between transcription factors and binding sites that lead to erroneous regulatory
states -- and understand the constraints this places on the design of regulatory
systems. I will then develop a generic theoretical framework to investigate the
coevolution of multiple transcription factors and multiple binding sites, in the
context of a gene regulatory network that performs a certain function. As a particular
tractable version of this problem, I will consider the evolution of two transcription
factors when they transmit upstream signals to downstream target genes. Specifically,
I will describe the evolutionary steady states and the evolutionary pathways involved,
along with their timescales, of a system that initially undergoes a transcription
factor duplication event. To connect this important theoretical model to the prominent
biological event of transcription factor duplication giving rise to paralogous
families, I will then describe a bioinformatics analysis of C2H2 Zn-finger transcription
factors, a major family in humans, and focus on the patterns of evolution that
paralogs have undergone in their various protein domains in the recent past. '

text: Pleiotropy is the well-established idea that a single mutation affects multiple
phenotypes. If a mutation has opposite effects on fitness when expressed in different
contexts, then genetic conflict arises. Pleiotropic conflict is expected to reduce
the efficacy of selection by limiting the fixation of beneficial mutations through
adaptation, and the removal of deleterious mutations through purifying selection.
Although this has been widely discussed, in particular in the context of a putative
“gender load,” it has yet to be systematically quantified. In this work, we empirically
estimate to which extent different pleiotropic regimes impede the efficacy of
selection in Drosophila melanogaster. We use whole-genome polymorphism data from
a single African population and divergence data from D. simulans to estimate the
fraction of adaptive fixations (α), the rate of adaptation (ωA), and the direction
of selection (DoS). After controlling for confounding covariates, we find that
the different pleiotropic regimes have a relatively small, but significant, effect
on selection efficacy. Specifically, our results suggest that pleiotropic sexual
antagonism may restrict the efficacy of selection, but that this conflict can
be resolved by limiting the expression of genes to the sex where they are beneficial.
Intermediate levels of pleiotropy across tissues and life stages can also lead
to maladaptation in D. melanogaster, due to inefficient purifying selection combined
with low frequency of mutations that confer a selective advantage. Thus, our study
highlights the need to consider the efficacy of selection in the context of antagonistic
pleiotropy, and of genetic conflict in general.

text: Cells need to reliably sense external ligand concentrations to achieve various
biological functions such as chemotaxis or signaling. The molecular recognition
of ligands by surface receptors is degenerate in many systems, leading to crosstalk
between ligand-receptor pairs. Crosstalk is often thought of as a deviation from
optimal specific recognition, as the binding of noncognate ligands can interfere
with the detection of the receptor's cognate ligand, possibly leading to a false
triggering of a downstream signaling pathway. Here we quantify the optimal precision
of sensing the concentrations of multiple ligands by a collection of promiscuous
receptors. We demonstrate that crosstalk can improve precision in concentration
sensing and discrimination tasks. To achieve superior precision, the additional
information about ligand concentrations contained in short binding events of the
noncognate ligand should be exploited. We present a proofreading scheme to realize
an approximate estimation of multiple ligand concentrations that reaches a precision
close to the derived optimal bounds. Our results help rationalize the observed
ubiquity of receptor crosstalk in molecular sensing.

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: We review the history of population genetics, starting with its origins a
century ago from the synthesis between Mendel and Darwin's ideas, through to the
recent development of sophisticated schemes of inference from sequence data, based
on the coalescent. We explain the close relation between the coalescent and a
diffusion process, which we illustrate by their application to understand spatial
structure. We summarise the powerful methods available for analysis of multiple
loci, when linkage equilibrium can be assumed, and then discuss approaches to
the more challenging case, where associations between alleles require that we
follow genotype, rather than allele, frequencies. Though we can hardly cover the
whole of population genetics, we give an overview of the current state of the
subject, and future challenges to it.

text: This paper analyzes how partial selfing in a large source population influences
its ability to colonize a new habitat via the introduction of a few founder individuals.
Founders experience inbreeding depression due to partially recessive deleterious
alleles as well as maladaptation to the new environment due to selection on a
large number of additive loci. I first introduce a simplified version of the Inbreeding
History Model (Kelly, 2007) in order to characterize mutation-selection balance
in a large, partially selfing source population under selection involving multiple
non-identical loci. I then use individual-based simulations to study the eco-evolutionary
dynamics of founders establishing in the new habitat under a model of hard selection.
The study explores how selfing rate shapes establishment probabilities of founders
via effects on both inbreeding depression and adaptability to the new environment,
and also distinguishes the effects of selfing on the initial fitness of founders
from its effects on the long-term adaptive response of the populations they found.
A high rate of (but not complete) selfing is found to aid establishment over a
wide range of parameters, even in the absence of mate limitation. The sensitivity
of the results to assumptions about the nature of polygenic selection are discussed.

text: Understanding the mechanisms causing phenotypic differences between females
and males has long fascinated evolutionary biologists. An extensive literature
exists on animal sexual dimorphism but less is known about sex differences in
plants, particularly the extent of geographical variation in sexual dimorphism
and its life-cycle dynamics. Here, we investigate patterns of genetically-based
sexual dimorphism in vegetative and reproductive traits of a wind-pollinated dioecious
plant, Rumex hastatulus, across three life-cycle stages using open-pollinated
families from 30 populations spanning the geographic range and chromosomal variation
(XY and XY1Y2) of the species. The direction and degree of sexual dimorphism was
highly variable among populations and life-cycle stages. Sex-specific differences
in reproductive function explained a significant amount of temporal change in
sexual dimorphism. For several traits, geographical variation in sexual dimorphism
was associated with bioclimatic parameters, likely due to the differential responses
of the sexes to climate. We found no systematic differences in sexual dimorphism
between chromosome races. Sex-specific trait differences in dioecious plants largely
result from a balance between sexual and natural selection on resource allocation.
Our results indicate that abiotic factors associated with geographical context
also play a role in modifying sexual dimorphism during the plant life cycle.

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: The spread of adaptive alleles is fundamental to evolution, and in theory,
this process is well‐understood. However, only rarely can we follow this process—whether
it originates from the spread of a new mutation, or by introgression from another
population. In this issue of Molecular Ecology, Hanemaaijer et al. (2018) report
on a 25‐year long study of the mosquitoes Anopheles gambiae (Figure 1) and Anopheles
coluzzi in Mali, based on genotypes at 15 single‐nucleotide polymorphism (SNP).
The species are usually reproductively isolated from each other, but in 2002 and
2006, bursts of hybridization were observed, when F1 hybrids became abundant.
Alleles backcrossed from A. gambiae into A. coluzzi, but after the first event,
these declined over the following years. In contrast, after 2006, an insecticide
resistance allele that had established in A. gambiae spread into A. coluzzi, and
rose to high frequency there, over 6 years (~75 generations). Whole genome sequences
of 74 individuals showed that A. gambiae SNP from across the genome had become
common in the A. coluzzi population, but that most of these were clustered in
34 genes around the resistance locus. A new set of SNP from 25 of these genes
were assayed over time; over the 4 years since near‐fixation of the resistance
allele; some remained common, whereas others declined. What do these patterns
tell us about this introgression event?

text: 'More than 100 years after Grigg’s influential analysis of species’ borders,
the causes of limits to species’ ranges still represent a puzzle that has never
been understood with clarity. The topic has become especially important recently
as many scientists have become interested in the potential for species’ ranges
to shift in response to climate change—and yet nearly all of those studies fail
to recognise or incorporate evolutionary genetics in a way that relates to theoretical
developments. I show that range margins can be understood based on just two measurable
parameters: (i) the fitness cost of dispersal—a measure of environmental heterogeneity—and
(ii) the strength of genetic drift, which reduces genetic diversity. Together,
these two parameters define an ‘expansion threshold’: adaptation fails when genetic
drift reduces genetic diversity below that required for adaptation to a heterogeneous
environment. When the key parameters drop below this expansion threshold locally,
a sharp range margin forms. When they drop below this threshold throughout the
species’ range, adaptation collapses everywhere, resulting in either extinction
or formation of a fragmented metapopulation. Because the effects of dispersal
differ fundamentally with dimension, the second parameter—the strength of genetic
drift—is qualitatively different compared to a linear habitat. In two-dimensional
habitats, genetic drift becomes effectively independent of selection. It decreases
with ‘neighbourhood size’—the number of individuals accessible by dispersal within
one generation. Moreover, in contrast to earlier predictions, which neglected
evolution of genetic variance and/or stochasticity in two dimensions, dispersal
into small marginal populations aids adaptation. This is because the reduction
of both genetic and demographic stochasticity has a stronger effect than the cost
of dispersal through increased maladaptation. The expansion threshold thus provides
a novel, theoretically justified, and testable prediction for formation of the
range margin and collapse of the species’ range.'

text: "One of the most striking and consistent results in speciation genomics is
the heterogeneous divergence observed across the genomes of closely related species.
This pattern was initially attributed to different levels of gene exchange—with
divergence preserved at loci generating a barrier to gene flow but homogenized
at unlinked neutral loci. Although there is evidence to support this model, it
is now recognized that interpreting patterns of divergence across genomes is not
so straightforward. One \r\nproblem is that heterogenous divergence between populations
can also be generated by other processes (e.g. recurrent selective sweeps or background
selection) without any involvement of differential gene flow. Thus, integrated
studies that identify which loci are likely subject to divergent selection are
required to shed light on the interplay between selection and gene flow during
the early phases of speciation. In this issue of Molecular Ecology, Rifkin et
al. (2019) confront this challenge using a pair of sister morning glory species.
They wisely design their sampling to take the geographic context of individuals
into account, including geographically isolated (allopatric) and co‐occurring
(sympatric) populations. This enabled them to show that individuals are phenotypically
less differentiated in sympatry. They also found that the loci that resist introgression
are enriched for those most differentiated in allopatry and loci that exhibit
signals of divergent selection. One great strength of the \r\nstudy is the combination
of methods from population genetics and molecular evolution, including the development
of a model to simultaneously infer admixture proportions and selfing rates."
