Data from: Costly infidelity: low lifetime fitness of extra-pair offspring in a passerine bird

Yu-Hsun Hsu, Julia Schroeder, Isabel Winney, Terry A. Burke, Shinichi Nakagawa & Terry Burke
Extra-pair copulation (EPC) is widespread in socially monogamous species, but its evolutionary benefits remain controversial. Indirect genetic benefit hypotheses postulate that females engage in EPC to produce higher quality extra-pair offspring (EPO) than within-pair offspring (WPO). In contrast, the sexual conflict hypothesis posits that EPC is beneficial to males but not to females. Thus, under the sexual conflict hypothesis, EPO are predicted to be no fitter than WPO. We tested these two hypotheses with a...

Data from: Selection from parasites favors immunogenetic diversity but not divergence among locally adapted host populations

Michael Tobler, Martin Plath, Rüdiger Riesch, Ingo Schlupp, Anna Grasse, Gopi K. Munimanda, Claudia Setzer, Dustin J. Penn & Yoshan Moodley
The unprecedented polymorphism in the major histocompatibility complex (MHC) genes is thought to be maintained by balancing selection from parasites. However, do parasites also drive divergence at MHC loci between host populations, or do the effects of balancing selection maintain similarities among populations? We examined MHC variation in populations of the livebearing fish Poecilia mexicana and characterized their parasite communities. Poecilia mexicana populations in the Cueva del Azufre system are locally adapted to darkness and...

Data from: The impact of translocations on neutral and functional genetic diversity within and among populations of the Seychelles warbler

David J. Wright, Lewis G. Spurgin, Nigel J. Collar, Jan Komdeur, Terry Burke & David S. Richardson
Translocations are an increasingly common tool in conservation. The maintenance of genetic diversity through translocation is critical for both the short and long term persistence of populations and species. However, the relative spatio-temporal impacts of translocations on neutral and functional genetic diversity and how this affects genetic structure among the conserved populations overall has received little investigation. We compared the impact of translocating different numbers of founders on both microsatellite and major histocompatibility complex (MHC)...

Data from: Human-facilitated metapopulation dynamics in an emerging pest species, Cimex lectularius

Toby Fountain, Gavin Horsburgh, Ludovic Duvaux, Klaus Reinhardt & Roger K. Butlin
The number and demographic history of colonists can have dramatic consequences for the way in which genetic diversity is distributed and maintained in a metapopulation. The bed bug (Cimex lectularius) is a re-emerging pest species whose close association with humans has led to frequent local extinction and colonisation, i.e. to metapopulation dynamics. Pest control limits the lifespan of sub-populations, causing frequent local extinctions, and human-facilitated dispersal allows the colonisation of empty patches. Founder events often...

Data from: Increased survival of experimentally evolved antimicrobial peptide-resistant Staphylococcus aureus in an animal host

Adam J. Dobson, Joanne Purves & Jens Rolff
Antimicrobial peptides (AMPs) have been proposed as new class of antimicrobial drugs, following the increasing prevalence of bacteria resistant to antibiotics. Synthetic AMPs are functional analogues of highly evolutionarily conserved immune effectors in animals and plants, produced in response to microbial infection. Therefore, the proposed therapeutic use of AMPs bears the risk of ‘arming the enemy’: bacteria that evolve resistance to AMPs may be cross-resistant to immune effectors (AMPs) in their hosts. We used a...

Data from: Outbreeding effects in an inbreeding insect, Cimex lectularius

Toby Fountain, Roger K. Butlin, Klaus Reinhardt & Oliver Otti
In some species, populations with few founding individuals can be resilient to extreme inbreeding. Inbreeding seems to be the norm in the common bed bug, Cimex lectularius, a flightless insect that, nevertheless, can reach large deme sizes and persist successfully. However, bed bugs can also be dispersed passively by humans, exposing inbred populations to gene flow from genetically distant populations. The introduction of genetic variation through this outbreeding could lead to increased fitness (heterosis) or...

Data from: Selection on outlier loci and their association with adaptive phenotypes in Littorina saxatilis contact zones

Johan Hollander, Juan Galindo & Roger K. Butlin
A fundamental issue in speciation research is to evaluate phenotypic variation and the genomics driving the evolution of reproductive isolation between sister taxa. Above all, hybrid zones are excellent study systems for researchers to examine the association of genetic differentiation, phenotypic variation and the strength of selection. We investigated two contact zones in the marine gastropod Littorina saxatilis and utilized landmark-based geometric morphometric analysis together with amplified fragment length polymorphism (AFLP) markers to assess phenotypic...

Data from: Scale-dependent effects of landscape variables on gene flow and population structure in bats

Orly Razgour, Hugo Rebelo, Sébastien J. Puechmaille, Javier Juste, Carlos Ibáñez, Andreas Kiefer, Terry Burke, Deborah A. Dawson & Gareth Jones
Aim: A common pattern in biogeography is the scale-dependent effect of environmental variables on the spatial distribution of species. We tested the role of climatic and land cover variables in structuring the distribution of genetic variation in the grey long-eared bat, Plecotus austriacus, across spatial scales. Although landscape genetics has been widely used to describe spatial patterns of gene flow in a variety of taxa, volant animals have generally been neglected because of their perceived...

Data from: At the Central European – Balkan transition: forest land snail faunas of the Banat contrasted with those of the Carpathian chain

Robert A. D. Cameron, Beata M. Pokryszko, Voichita Gheoca & Michal Horsák
Twenty-nine forest sites in six sampling areas in the Banat region of Romania, adjacent to Serbia, were sampled to obtain inventories of their snail faunas and to make comparisons between these and previously studied faunas in the mountains from the Sudetes in the north-west to the Southern Transylvanian Carpathians in the south. 65 species were recorded overall, with between 13 and 33 at individual sites. Among the six sampling areas that on Schist rock at...

Data from: Museum DNA reveals the demographic history of the endangered Seychelles warbler

Lewis G. Spurgin, David J. Wright, Nigel J. Collar, Marco Van Der Velde, Jan Komdeur, Terry Burke & David S. Richardson
The importance of evolutionary conservation – how understanding evolutionary forces can help guide conservation decisions – is widely recognized. However, the historical demography of many endangered species is unknown, despite the fact that this can have important implications for contemporary ecological processes and for extinction risk. Here, we reconstruct the population history of the Seychelles warbler (Acrocephalus sechellensis) – an ecological model species. By the 1960s, this species was on the brink of extinction, but...

Data from: Theoretical models of the influence of genomic architecture on the dynamics of speciation

Samuel M. Flaxman, Aaron C. Wacholder, Jeffrey L. Feder & Patrik Nosil
A long-standing problem in evolutionary biology has been determining whether and how gradual, incremental changes at the gene level can account for rapid speciation and bursts of adaptive radiation. Using genome-scale computer simulations, we extend previous theory showing how gradual adaptive change can generate nonlinear population transitions, resulting in the rapid formation of new, reproductively isolated species. We show that these transitions occur via a mechanism rooted in a basic property of biological heredity: the...

Data from: The crested newt Triturus cristatus recolonized temperate Eurasia from an extra-Mediterranean glacial refugium

Ben Wielstra, Wiesław Babik & Jan W. Arntzen
We assess the role of the Carpathians as an extra-Mediterranean glacial refugium for the crested newt Triturus cristatus. We combine a multilocus phylogeography (one mitochondrial protein-coding gene, three nuclear introns, and one major histocompatibility complex gene) with species distribution modelling (projected on current and Last Glacial Maximum climate layers). All genetic markers consistently show extensive genetic variation within and genetic depletion outside the Carpathians. The species distribution model suggests that most of the current range...

Data from: Sexual conflict and interacting phenotypes: a quantitative genetic analysis of fecundity and copula duration in Drosophila melanogaster

Dominic Alexander Edward, Jocelyn Poissant, Alastair J. Wilson & Tracey Chapman
Many reproductive traits that have evolved under sexual conflict may be influenced by both sexes. Investigation of the genetic architecture of such traits can yield important insight into their evolution, but this entails that the heritable component of variation is estimated for males and females – as an interacting phenotype. We address the lack of research in this area through an investigation of egg production and copula duration in the fruit fly, Drosophila melanogaster. Despite...

Data from: Cuckoo hosts shift from accepting to rejecting parasitic eggs across their lifetime

Mercedes Molina-Morales, David Martín-Gálvez, Deborah A. Dawson, Terry A. Burke, Jesús Miguel Avilés & Juan Gabriel Martínez
One of the best known outcomes of coevolution between species is the rejection of mimetic parasite eggs by avian hosts, which has evolved to reduce costly cuckoo parasitism. How this behavioral adaptation varies along the life of individual hosts remains poorly understood. Here we identify for the first time, lifetime patterns of egg rejection in a parasitized long-lived bird, the magpie Pica pica and show that, during the years they were studied, some females accept,...

Data from: High bandwidth synaptic communication and frequency tracking in human neocortex

Guilherme Testa-Silva, Matthijs B. Verhoog, Daniele Linaro, Christiaan P. J. De Kock, Johannes C. Baayen, Rhiannon M. Meredith, Chris I. De Zeeuw, Michele Giugliano & Huibert D. Mansvelder
Neuronal firing, synaptic transmission, and its plasticity form the building blocks for processing and storage of information in the brain. It is unknown whether adult human synapses are more efficient in transferring information between neurons than rodent synapses. To test this, we recorded from connected pairs of pyramidal neurons in acute brain slices of adult human and mouse temporal cortex and probed the dynamical properties of use-dependent plasticity. We found that human synaptic connections were...

Data from: Do the same genes underlie parallel phenotypic divergence in different Littorina saxatilis populations?

Anja M. Westram, Juan Galindo, Magnus Alm Rosenblad, John W. Grahame, Marina Panova & Roger K. Butlin
Parallel patterns of adaptive divergence and speciation are cited as powerful evidence for the role of selection driving these processes. However, it is often not clear whether parallel phenotypic divergence is underlain by parallel genetic changes. Here, we asked about the genetic basis of parallel divergence in the marine snail Littorina saxatilis, which has repeatedly evolved coexisting ecotypes adapted to either crab predation or wave action. We sequenced the transcriptome of snails of both ecotypes...

Data from: A generalized residual technique for analyzing complex movement models using earth mover's distance

Jonathan R. Potts, Marie Auger-Méthé, Karl Mokross & Mark A. Lewis
1. Complex systems of moving and interacting objects are ubiquitous in the natural and social sciences. Predicting their behavior often requires models that mimic these systems with sufficient accuracy, while accounting for their inherent stochasticity. Though tools exist to determine which of a set of candidate models is best relative to the others, there is currently no generic goodness-of-fit framework for testing how close the best model is to the real complex stochastic system. 2....

Data from: Parallel tagged amplicon sequencing of transcriptome-based genetic markers for Triturus newts with the Ion Torrent next-generation sequencing platform

Ben Wielstra, Elza Duijm, Patricia Lagler, Youri Lammers, Willem R. M. Meilink, Janine M. Ziermann & Jan W. Arntzen
Next-generation sequencing is a fast and cost-effective way to obtain sequence data for non-model organisms for many markers and for many individuals. We describe a protocol through which we obtain orthologous markers for the crested newts (Amphibia: Salamandridae: Triturus), suitable for analysis of interspecific hybridization. We use transcriptome data of a single Triturus species and design 96 primer pairs that amplify c. 180 bp fragments positioned in 3-prime untranslated regions. Next these markers are tested...

Data from: Neighbouring-group composition and within-group relatedness drive extra-group paternity rate in the European badger (Meles meles)

Geetha Annavi, Chris Newman, Hannah L. Dugdale, Christina C. Buesching, Yung W. Sin, Terry Burke & David W. Macdonald
Extra-group paternity (EGP) occurs commonly among group-living mammals and plays an important role in mating systems and the dynamics of sexual selection; however, socio-ecological and genetic correlates of EGP have been underexplored. We use 23 years of demographic and genetic data from a high-density European badger (Meles meles) population, to investigate the relationship between the rate of EGP in litters and mate availability, mate incompatibility and mate quality (heterozygosity). Relatedness between within-group assigned mothers and...

Data from: Re-visiting the phylogeography and demography of European badgers (Meles meles) based on broad sampling, multiple markers and simulations

Alain C. Frantz, Allan D. McDevitt, Lisa C. Pope, Joanna Kochan, John Davison, Chris F. Clements, Morten Elmeros, Guillem Molina-Vacas, Aritz Ruiz-Gonzalez, Alessandro Balestrieri, Koen Van Den Berge, Peter Breyne, Emmanuel Do Linh San, Erik O. Ågren, Franz Suchentrunk, Laurent Schley, Rafał Kowalczyk, Berit I. Kostka, Dusko Ćirović, Nikica Šprem, Marc Colyn, Marco Ghirardi, Venislava Racheva, Christophe Braun, Rita Oliveira … & Terry Burke
Although the phylogeography of European mammals has been extensively investigated since the 1990s, many studies were limited in terms of sampling distribution, the number of molecular markers used and the analytical techniques employed, frequently leading to incomplete postglacial recolonisation scenarios. The broad-scale genetic structure of the European badger (Meles meles) is of interest as it may result from historic restriction to glacial refugia and/or recent anthropogenic impact. However, previous studies were based mostly on samples...

Data from: Early reproductive investment, senescence and lifetime reproductive success in female Asian elephants

Adam D. Hayward, Khyne U. Mar, Mirkka Lahdenperä & Virpi Lummaa
The evolutionary theory of senescence posits that as the probability of extrinsic mortality increases with age, selection should favour early-life over late-life reproduction. Studies on natural vertebrate populations show early reproduction may impair later-life performance, but the consequences for lifetime fitness have rarely been determined, and little is known of whether similar patterns apply to mammals which typically live for several decades. We used a longitudinal dataset on Asian elephants (Elephas maximus) to investigate associations...

Data from: Cooperative investment in public goods is kin directed in communal nests of social birds

René E. Van Dijk, Jennifer C. Kaden, Araceli Argüelles-Ticó, Deborah A. Dawson, Terry Burke & Ben J. Hatchwell
The tragedy of the commons predicts social collapse when public goods are jointly exploited by individuals attempting to maximise their fitness at the expense of other social group members. However, animal societies have evolved many times despite this vulnerability to exploitation by selfish individuals. Kin selection offers a solution to this social dilemma, but in large social groups mean relatedness is often low. Sociable weavers (Philetairus socius) live in large colonies that share the benefits...

Data from: The dynamics of recovery and growth: how defoliation affects stored resources

Rebecca R. L. Atkinson, Mike M. Burrell, Karen E. Rose, Colin P. Osborne & Mark Rees
Growth rate varies widely among species and the trade-off between growth rate and storage or maintenance traits is a principal axis of variation between species. Many plant species have substantial root stores, but very little is known about how growth rate modifies responses of these stores to defoliation and other stresses. Species with different growth rates are predicted to respond in distinct ways, because of variation in the pre-defoliation allocation to storage. Here, we quantified...

Data from: Data concatenation, Bayesian concordance and coalescent-based analyses of the species tree for the rapid radiation of Triturus newts

Ben Wielstra, Jan W. Arntzen, Kristiaan J. Van Der Gaag, Maciej Pabijan & Wieslaw Babik
The phylogenetic relationships for rapid species radiations are difficult to disentangle. Here we study one such case, namely the genus Triturus, which is composed of the marbled and crested newts. We analyze data for 38 genetic markers, positioned in 3-prime untranslated regions of protein-coding genes, obtained with 454 sequencing. Our dataset includes twenty Triturus newts and represents all nine species. Bayesian analysis of population structure allocates all individuals to their respective species. The branching patterns...

Data from: Assessing risks of invasion through gamete performance: farm Atlantic salmon sperm and eggs show equivalence in function, fertility, compatibility and competitiveness to wild Atlantic salmon

Sarah E. Yeates, Sigurd Einum, William V. Holt, Ian A. Fleming & Matthew J. G. Gage
Adaptations at the gamete level (a) evolve quickly, (b) appear sensitive to inbreeding and outbreeding and (c) have important influences on potential to reproduce. We apply this understanding to problems posed by escaped farm salmon and measure their potential to reproduce in the wild. Farm Atlantic salmon (Salmo salar) are a threat to biodiversity, because they escape in large numbers and can introgress, dilute or disrupt locally adapted wild gene pools. Experiments at the whole...
