Data from: Selective pressures on MHC class II genes in the guppy (Poecilia reticulata) as inferred by hierarchical analysis of population structure.

Magdalena Herdegen, Wieslaw Babik & Jacek Radwan
Genes of the major histocompatibility complex, which are the most polymorphic of all vertebrate genes, are a pre-eminent system for the study of selective pressures that arise from host–pathogen interactions. Balancing selection capable of maintaining high polymorphism should lead to the homogenization of MHC allele frequencies among populations, but there is some evidence to suggest that diversifying selection also operates on the MHC. However, the pattern of population structure observed at MHC loci is likely...

Data from: Haldane’s rule revisited: do hybrid females have a shorter lifespan? Survival of hybrids in a recent contact zone between two large gull species

Grzegorz Neubauer, Piotr Nowicki & Magdalena Zagalska-Neubauer
Haldane’s rule predicts that particularly high fitness reduction should affect the heterogametic sex of interspecific hybrids. Despite the fact that hybridization is widespread in birds, survival of hybrid individuals is rarely addressed in studies of avian hybrid zones, possibly because of methodological constraints. Here, having applied capture-mark-recapture models to an extensive, 19-year-long dataset on individually marked birds, we estimate annual survival rates of hybrid individuals in the hybrid zone between herring (Larus argentatus) and Caspian...

Data from: Development, validation and high-throughput analysis of sequence markers in nonmodel species

Piotr Zieliński, Michal T. Stuglik, Katarzyna Dudek, Mateusz Konczal & Wieslaw Babik
DNA sequences derived from multiple regions of the nuclear genome are essential for historical inferences in the fields of phylogeography and phylogenetics. The appropriate markers should be single-copy, variable, easy to amplify from multiple samples and easy to sequence using high-throughput technologies. This may be difficult to achieve for species lacking sequenced genomes and particularly challenging for species possessing large genomes, which consist mostly of repetitive sequences. Here, we present a cost-effective, broadly applicable framework...

Data from: Single nucleotide polymorphisms reveal genetic structuring of the Carpathian newt and provide evidence of interspecific gene flow in the nuclear genome

Piotr Zieliński, Katarzyna Dudek, Michał Tadeusz Stuglik, Marcin Liana & Wiesław Babik
Genetic variation within species is commonly structured in a hierarchical manner which may result from superimposition of processes acting at different spatial and temporal scales. In organisms of limited dispersal ability, signatures of past subdivision are detectable for a long time. Studies of contemporary genetic structure in such taxa inform about the history of isolation, range changes and local admixture resulting from geographically restricted hybridization with related species. Here we use a set of 139...

Data from: Sex-specific effects of natural and sexual selection on the evolution of life span and ageing in Drosophila simulans

Catharine Ruth Archer, Eoin Duffy, David J. Hosken, Mikael Mokkonen, Kensuke Okada, Keiko Oku, Manmohan D. Sharma & John Hunt
1. Variation in the strength of age-dependent natural selection shapes differences in ageing rates across species and populations. Likewise, sexual selection can promote divergent patterns of senescence across the sexes. However, the effects of these processes on the evolution of ageing have largely been considered independently, and interactions between them are poorly understood. 2. We use experimental evolution to investigate how natural and sexual selection affect life span and ageing in Drosophila simulans. 3. Replicate...

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: Parasite load and MHC diversity in undisturbed and agriculturally modified habitats of the ornate dragon lizard

Jacek Radwan, Katarzyna Kuduk, Esther Levy, Natasha LeBas & Wieslaw Babik
MHC gene polymorphism is thought to be driven by host-parasite coevolution, but the evidence for an association between the selective pressure from parasites and the number of MHC alleles segregating in a population is scarce and inconsistent. Here, we characterized MHC class I polymorphism in a lizard whose habitat preferences (rock outcrops) lead to the formation of well-defined and stable populations. We investigated the association between the load of ticks, which were used as a...

Data from: Sexual selection and the evolution of the Major Histocompatibility Complex

Maciej Jan Ejsmond, Jacek Radwan & Anthony B. Wilson
The genes of the major histocompatibility complex (MHC) are a key component of the adaptive immune system and among the most variable loci in the vertebrate genome. Pathogen-mediated natural selection and MHC-based disassortative mating are both thought to structure MHC polymorphism, but their effects have proven difficult to discriminate in natural systems. Using the first model of MHC dynamics incorporating both survival and reproduction, we demonstrate that natural and sexual selection produce distinctive signatures of...

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: Experimentally increased reproductive effort alters telomere length in the blue tit (Cyanistes caeruleus)

Joanna Sudyka, Aneta Arct, Szymon Drobniak, Anna Dubiec, Lars Gustafsson & Mariusz Cichoń
Telomeres have recently been suggested to play important role in ageing and are considered to be a reliable ageing biomarkers. The life history theory predicts that costs of reproduction should be expressed in terms of accelerated senescence, and some empirical studies do confirm such presumption. Thus, a link between reproductive effort and telomere dynamics should be anticipated. Recent studies have indeed demonstrated that reproduction may trigger telomere loss, but actual impact of reproductive effort has...

Data from: Selection for alternative male reproductive tactics alters intralocus sexual conflict

Agata Plesnar-Bielak, Anna Skrzynecka, Krzysztof Miler, Jacek Radwan, Agata Plesnar Bielak & Anna M. Skrzynecka
Intralocus sexual conflict (IASC) arises when fitness optima for a shared trait differ between the sexes; such conflict may help maintain genetic variation within populations. Sex-limited expression of sexually antagonistic traits may help resolve the conflict, but the extent of this resolution remains a subject of debate. In species with alternative male reproductive tactics, unresolved conflict should manifest more in a more sexually dimorphic male phenotype. We tested this prediction in the bulb mite (Rhizoglyphus...
