Unravelling the genomic landscape of divergence between lineages is key to understanding speciation. The naturally hybridizing collared flycatcher and pied are important avian speciation models that show pre- as well postzygotic isolation. We sequenced assembled 1.1-Gb genome, physically mapped assembly chromosomes using a low-density linkage map re-sequenced population samples each species. Here we species differentiation highly heterogeneous with approximately 50 'divergence islands'...
Global climate fluctuations have significantly influenced the distribution and abundance of biodiversity [1Williams D. Dunkerly DeDeckker P. Kershaw Chappell M. Quaternary Environments. Arnold, 1988Google Scholar]. During unfavorable glacial periods, many species experienced range contraction fragmentation, expanding again during interglacials [2Hewitt G. The genetic legacy ice ages.Nature. 2000; 405: 907-913Crossref PubMed Scopus (5266) Google Scholar, 3Hewitt G.M. Genetic consequences...
Abstract Climatic fluctuations during the Quaternary period governed demography of species and contributed to population differentiation ultimately speciation. Studies these past processes have previously been hindered by a lack means genetic data model changes in effective size ( N e ) through time. However, based on diploid genome sequences high quality, recently developed pairwise sequentially Markovian coalescent PSMC can estimate trajectories over considerable time periods. We applied...
Profound knowledge of demographic history is a prerequisite for the understanding and inference processes involved in evolution population differentiation speciation. Together with new coalescent-based methods, recent availability genome-wide data enables investigation divergence at unprecedented depth. We combined two powerful approaches, full Approximate Bayesian Computation analysis (ABC) pairwise sequentially Markovian coalescent modeling (PSMC), to reconstruct split between avian...
Abstract Patterns of interspecific introgression may vary geographically, and the distribution introgressed variants can yield insight into historical dynamics genetic interactions between hybridizing species. Urodele amphibians, often characterized by limited mobility, deep intraspecific structuring vulnerability to climatic changes, constitute suitable models for such inferences. Here, we combine an extensive survey mitochondrial (mt DNA ) nuclear (15 microsatellites) genomes in C...
The nearly neutral theory of molecular evolution predicts that small populations should accumulate deleterious mutations at a faster rate than large populations. analysis nonsynonymous (dN) versus synonymous (dS) substitution rates in birds mammals, however, has provided contradictory results, questioning the generality theory. Here we analyzed impact life history traits, taken as proxies effective population size, on evolutionary and genetic processes amniotes, including so far neglected...
Abstract Effective population size, Ne, is a key evolutionary parameter that determines the levels of genetic variation and efficacy selection. Estimation interpretation Ne are essential in diverse areas conservation biology, ranging from assessing potential or extinction risk to empowering research on genomic basis adaptation. The applications concept resulted largely independent methodological developments using different definitions focusing estimation either contemporary long‐term Ne....
Abstract Exact location and number of glacial refugia still remain unclear for many European cold‐blooded terrestrial vertebrates. We performed a fine‐scaled multilocus phylogeographic analysis two Bombina species combining mitochondrial variation 950 toads from 385 sites nuclear genes ( Rag‐1, Ncx‐1 ) subset samples to reconstruct their colonization contemporary patterns. identified the lowlands northwest Black Sea Carpathians be important refugial areas B. bombina variegata, respectively....
Theoretical work suggests that sexual conflict should promote the maintenance of genetic diversity by opposing directions selection on males and females. If such is pervasive, it could potentially lead to genomic heterogeneity in levels an idea so far has not been empirically tested a genomewide scale. We used large-scale population transcriptomic data from collared flycatcher (Ficedula albicollis) analyse how conflict, for which we use sex-biased gene expression as proxy, relates...
Genomes retain evidence of the demographic history and evolutionary forces that have shaped populations drive speciation. Across island systems, contemporary patterns genetic diversity reflect population demography, including colonization events, bottlenecks, gene flow drift. Here, we investigate genome-wide distribution runs homozygosity (ROH) using whole-genome resequencing individuals (>22× coverage) from six across three archipelagos Berthelot's pipit (Anthus berthelotii)-a passerine has...
Understanding the process of divergence requires quantitative characterization patterns gene flow between diverging taxa. New and powerful coalescent-based methods give insight into these processes in unprecedented details by enabling reconstruction temporal distribution past flow. Here, we use sequence variation at eight nuclear markers mitochondrial DNA (mtDNA) multiple populations to study diversity, divergence, two subspecies a salamander, smooth newt (Lissotriton vulgaris kosswigi...
Abstract Our understanding of the evolutionary mechanisms generating variation within highly polymorphic major histocompatibility complex (MHC) genes remains incomplete. Assessing MHC across multiple populations, recent and ancient divergence, may facilitate geographical temporal aspects variation. Here, we applied 454 sequencing to perform a large‐scale, comprehensive analysis class II in closely related, hybridizing newts, Lissotriton vulgaris ( Lv ) montandoni Lm ). study revealed an...
ABSTRACT Eurasian spruce bark beetle Ips typographus , a natural part of forest ecosystems, is major threat to Norway forests during outbreaks. Olfaction plays crucial role in the survival and range expansion these beetles, amid disturbances climate change. As current management strategies are suboptimal for controlling outbreaks, reverse chemical ecology approaches based on pheromone receptors offer promising alternatives. While search progress, recently found chromosomal inversions...
Abstract Due to its central importance many aspects of evolutionary biology and population genetics, the long‐term effective size ( N e ) has been estimated for numerous species populations. However, estimating contemporary is difficult in practice this parameter often unknown. In principle, can be using either analyses temporal changes allele frequencies, or extent linkage disequilibrium (LD) between unlinked markers. We applied these approaches estimate a relatively recently founded island...
Abstract Information about demographic history is essential for the understanding of processes divergence and speciation. Patterns genetic variation within between closely related species provide insights into their interactions. Here, we investigated historical demography exchange Carpathian ( Lissotriton montandoni , Lm) smooth L. vulgaris Lv) newts. We combine an extensive geographical sampling multilocus nuclear sequence data with approximate Bayesian computation framework to test...
Abstract Detecting positive selection using genomic data is critical to understanding the role of adaptive evolution. Of particular interest in this context sex chromosomes since they are thought play a special local adaptation and speciation. We sought circumvent challenges associated with statistical phasing when haplotype‐based statistics sweep scans by benefitting from that whole chromosome haplotypes can be obtained resequencing individuals hemizygous sex. analyzed Z 100 females several...
Abstract In many species, polymorphic inversions underlie complex phenotypic polymorphisms and facilitate local adaptation in the face of gene flow. Multiple can co-occur a genome, but prevalence, evolutionary significance, limits to complexity genomic inversion landscapes remain poorly understood. Here, we examine genome-wide variation one Europe’s most destructive forest pests, spruce bark beetle Ips typographus , scan for inversions, test whether are involved key adaptations this species....

Abstract Both genome‐wide heterozygosity and at major histocompatibility complex ( MHC ) genes are often associated with higher fitness. Recent theoretical work indicates that sexual ornaments may reveal information about individual heterozygosity, preference for such benefit females via the increased of their progeny. Here, we used path analysis to investigate direct indirect (via body size as an index condition) effects six microsatellite loci class II DAB gene on a ornament, crest, in...
Centricnemus leucogrammus is a weevil characteristic of European xerothermic habitats and steppes. The species was probably more widespread during the Pleistocene glaciations, while its current distribution limited to "warm-stage refugia." It may be regarded as typical representative flightless xerothermophilous beetles. Previous studies concentrated on genetic variation using mitochondrial genes. Here, we identified, tested characterized 24 polymorphic microsatellite loci with use 454...
