Data from: Patterns of MHC-dependent mate selection in humans and non-human primates: a meta-analysis

Jamie Winternitz, Jessica Abbate, Elise Huchard, Jan Havlíček & Laszlo Z. Garamszegi
Genes of the major histocompatibility complex (MHC) in vertebrates are integral for effective adaptive immune response and are associated with sexual selection. Evidence from a range of vertebrates supports MHC-based preference for diverse and dissimilar mating partners, but evidence from human mate choice studies has been disparate and controversial. Methodologies and sampling peculiarities specific to human studies make it difficult to know whether wide discrepancies in results among human populations are real or artefact. To...

Data from: Phenotypic differentiation is associated with divergent sexual selection among closely related barn swallow populations

Sexual selection plays a key role in the diversification of numerous animal clades and may accelerate trait divergence during speciation. However, much of our understanding of this process comes from phylogenetic comparative studies, which rely on surrogate measures such as dimorphism that may not represent selection in wild populations. In this study, we assess sexual selection pressures for multiple male visual signals across four barn swallow (Hirundo rustica) populations. Our sample encompassed 2400 linear km...

Data from: Egg morphology fails to identify nests parasitized by conspecifics in common pochard: a test based on protein fingerprinting and including female relatedness

Adéla Petrželková, Hannu Pöysä, Petr Klvaňa, Tomáš Albrecht & David Hořák
Conspecific brood parasites lay eggs in nests of other females of the same species. A variety of methods have been developed and used to detect conspecific brood parasitism (CBP). Traditional methods may be inaccurate in detecting CBP and in revealing its true frequency. On the other hand more accurate molecular methods are expensive and time consuming. Eadie developed a method for revealing CBP based on differences in egg morphology. That method is based on Euclidean...

Data from: Para-allopatry in hybridizing fire-bellied toads (Bombina bombina and B. variegata): inference from transcriptome-wide coalescence analyses

Beate Nürnberger, Konrad Lohse, Anna Fijarczyk, Jacek M. Szymura & Mark L. Blaxter
Ancient origins, profound ecological divergence, and extensive hybridization make the fire-bellied toads Bombina bombina and B. variegata (Anura: Bombinatoridae) an intriguing test case of ecological speciation. Previous modeling has proposed that the narrow Bombina hybrid zones represent strong barriers to neutral introgression. We test this prediction by inferring the rate of gene exchange between pure populations on either side of the intensively studied Kraków transect. We developed a method to extract high confidence sets of...

Data from: Genetic distinction between contiguous urban and rural multimammate mice in Tanzania despite gene flow

Sophie Gryseels, Joëlle Goüy De Bellocq, Rhodes Makundi, Kurt Vanmechelen, Jan Broeckhove, Vladimír Mazoch, Radim Šumbera, , Herwig Leirs & Stuart J. E. Baird
Special conditions are required for genetic differentiation to arise at a local geographical scale in the face of gene flow. The Natal multimammate mouse, Mastomys natalensis, is the most widely distributed and abundant rodent in sub-Saharan Africa. A notorious agricultural pest and a natural host for many zoonotic diseases, it can live in close proximity to man, and appears to compete with other rodents for the synanthropic niche. We surveyed its population genetic structure across...

Data from: Metazoan parasites of African annual killifish (Nothobranchiidae): abundance, diversity, and their environmental correlates

Veronika Nezhybová, Martin Reichard, Radim Blažek & Markéta Ondračková.
Estimates of biodiversity and its global patterns are affected by parasite richness and specificity. Despite this, parasite communities are largely neglected in biodiversity estimates, especially in the tropics. We studied the parasites of annual killifish of the genus Nothobranchius that inhabit annually desiccating pools across the African savannah and survive the dry period as developmentally arrested embryos. Their discontinuous, non-overlapping generations make them a unique organism in which to study natural parasite fauna. We investigated...

Data from: Repeated intraspecific divergence in life span and aging of African annual fishes along an aridity gradient

Radim Blažek, Matej Polacik, Petr Kacer, Alessandro Cellerino, Radomil Řežucha, Caroline Methling, Oldrich Tomasek, Kaila Syslova, Eva Terzibasi-Tozzini, Tomas Albrecht, Milan Vrtílek & Martin Reichard
Life span and aging are substantially modified by natural selection. Across species, higher extrinsic (environmentally related) mortality (and hence shorter life expectancy) selects for the evolution of more rapid aging. However, among populations within species, high extrinsic mortality can lead to extended life span and slower aging as a consequence of condition-dependent survival. Using within-species contrasts of eight natural populations of Nothobranchius fishes in common garden experiments, we demonstrate that populations originating from dry regions...

Data from: Empirical evidence for large X-effects in animals with undifferentiated sex chromosomes

Christophe Dufresnes, Tomasz Majtyka, Stuart J. E. Baird, Jörn F. Gerchen, Amaël Borzée, Romain Savary, Maria Ogielska, Nicolas Perrin & Matthias Stöck
Reproductive isolation is crucial for the process of speciation to progress. Sex chromosomes have been assigned a key role in driving reproductive isolation but empirical evidence from natural population processes has been restricted to organisms with degenerated sex chromosomes such as mammals and birds. Here we report restricted introgression at sex-linked compared to autosomal markers in a hybrid zone between two incipient species of European tree frog, Hyla arborea and H. orientalis, whose homologous X...

Data from: Phylogeographic analysis reveals northerly refugia for the riverine amphibian Triturus dobrogicus (Caudata: Salamandridae)

Judit Vörös, Peter Mikulíček, Ágnes Major, Ernesto Recuero & Jan W. Arntzen
We investigated the recent evolutionary history of the Danube crested newt, Triturus dobrogicus through reconstructions of: (1) the number and position of refugia at the last glacial maximum, (2) the role of major central European rivers in pattern of post-glacial dispersal, and (3) the present-day distribution pattern. We analysed sequences of mitochondrial DNA (ND2, 1065 bp) and six microsatellite loci in 363 T. dobrogicus individuals from 58 populations covering the range of the species. Our...
