Data from: Re-visiting the phylogeography and demography of European badgers (Meles meles) based on broad sampling, multiple markers and simulationsAlain C. Frantz, Allan D. McDevitt, Lisa C.

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...
Drosophila simulans is a closely relative of the genetic model D. melanogaster. In an effort to improve the genomic resources for D. simulans, we assembled and annotated the genome of a strain originating from Madagascar (M252), the ancestral range of D. simulans. The comparison of the M252 genome to other available D. simulans assemblies confirmed its high quality, but also highlighted genomic regions that are difficult to assemble with NGS data. The annotation of M252...
Data from: Patterns of linkage disequilibrium and long range hitchhiking in evolving experimental Drosophila melanogaster populationsSusanne U. Franssen, Viola Nolte, Ray Tobler & Christian Schlötterer
Whole genome re-sequencing of experimental populations evolving under a specific selection regime has become a popular approach to determine genotype-phenotype maps and understand adaptation to new environments. Despite its conceptual appeal and success in identifying some causative genes, it has become apparent that many studies suffer from an excess of candidate loci. Several explanations have been proposed for this phenomenon, but it is clear that information about the linkage structure during such experiments is needed....
The conservation of large carnivores is a formidable challenge for biodiversity conservation. Using a data set on the past and current status of brown bears (Ursus arctos), Eurasian lynx (Lynx lynx), gray wolves (Canis lupus), and wolverines (Gulo gulo) in European countries, we show that roughly one-third of mainland Europe hosts at least one large carnivore species, with stable or increasing abundance in most cases in 21st-century records. The reasons for this overall conservation success...
Data from: A Drosophila laboratory evolution experiment points to low evolutionary potential under increased temperatures likely to be experienced in the futureMads F. Schou, Torsten N. Kristensen, Vanessa Kellermann, Christian Schlötterer & Volker Loeschcke
The ability to respond evolutionarily to increasing temperatures is important for survival of ectotherms in a changing climate. Recent studies suggest that upper thermal limits may be evolutionary constrained. We address this hypothesis in a laboratory evolution experiment, encompassing ecologically relevant thermal regimes. To examine the potential for species to respond to climate change, we exposed replicate populations of Drosophila melanogaster to increasing temperatures (0.3 °C every generation) for 20 generations, whereas corresponding replicate control...
Data from: \"De novo transcriptome assembly of the mountain fly Drosophila nigrosparsa using short RNA-seq reads\" in Genomic Resources Notes Accepted 1 August 2014-30 September 2014Wolfgang Arthofer, Francesco Cicconardi, Nicola Palmieri, Viola Nolte, Christian Schlötterer, Birgit C. Schlick-Steiner, Florian M. Steiner, Marcelo Vallinoto, David A. Weese, B. L. Banbury, R. B. Harris, David S. Kang, Cheolho Sim, Thomas F. Duda, A. D. Leaché, Miguel Carneiro, Coralie Nourisson & Fernando Sequeira
Drosophila (Drosophila) nigrosparsa is a habitat specialist restricted to the European montane/alpine zone (Bächli 2008). Mountain biodiversity is considered highly vulnerable to ongoing climate warming (IPCC 2013), and organisms at high altitudes have only limited possibility to shift to cooler habitats at elevations above (Pertoldi & Bach 2007). For such species, rapid evolution may offer a solution for long-term survival. We are establishing D. nigrosparsa as a model system to test the extent and tempo...
Data from: Temperature stress mediates decanalization and dominance of gene expression in Drosophila melanogasterJun Chen, Viola Nolte & Christian Schlötterer
The regulatory architecture of gene expression remains an area of active research. Here, we studied how the interplay of genetic and environmental variation affects gene expression by exposing Drosophila melanogaster strains to four different developmental temperatures. At 18°C we observed almost complete canalization with only very few allelic effects on gene expression. In contrast, at the two temperature extremes, 13°C and 29°C a large number of allelic differences in gene expression were detected due to...
Data from: Selection from parasites favors immunogenetic diversity but not divergence among locally adapted host populationsMichael 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...
Orphans are genes restricted to a single phylogenetic lineage and emerge at high rates. While this predicts an accumulation of genes, the gene number has remained remarkably constant through evolution. This paradox has not yet been resolved. Because orphan genes have been mainly analyzed over long evolutionary time scales, orphan loss has remained unexplored. Here we study the patterns of orphan turnover among close relatives in the Drosophila obscura group. We show that orphans are...
