The cladoceran Daphnia lumholtzi is a subtropical and tropical zooplankter, and an invasive species in North America. Thus far, D. lumholtzi has not been detected in Europe. Here we investigated whether a hypothetical introduction to Europe could result in a successful invasion, either now or in the near future when facilitated by climate change. In laboratory experiments, we tested whether different clones of D. lumholtzi can invade a resident community consisting of native Daphnia from...
Data from: A morphometric and genetic framework for the genus Gazella de Blainville, 1816 (Ruminantia: Bovidae) with special focus on Arabian and Levantine mountain gazellesEva V. Bärmann, Torsten Wronski, Hannes Lerp, Beatriz Azanza, Saskia Börner, Dirk Erpenbeck, Gertrud E. Rössner & Gert Wörheide
Gazella is one of the most species-rich genera within horned ruminants. Despite overall similarity in body size and morphology, gazelles show variability in coloration and horn morphology. Unfortunately, however, species differentiation based on these characters, or on discrete skull characters, is very difficult due to high intraspecific variability. Furthermore, most species have fragmented and allopatric distributions, so that species boundaries were hard to define in the past. Mitochondrial DNA sequences have proven useful for investigating...
Data from: Capturing the population structure of microparasites: using ITS-sequence data and a pooled DNA approachSabine Giessler & Justyna Wolinska
The internal transcribed spacer (ITS) region of nuclear ribosomal DNA is a common marker not only for the molecular identification of different taxa and strains, but also for the analysis of population structure of wild microparasite communities. Importantly, the multicopy nature of this region allows the amplification of low-quantity samples of the target DNA, a common problem in studies on unicellular, unculturable microparasites. We analysed ITS sequences from the protozoan parasite Caullerya mesnili (class Ichthyosporea)...
Data from: 'Escaping' the X chromosome leads to increased gene expression in the male germline of Drosophila melanogasterClaus Kemkemer, Ana Catalán & John Parsch
Genomic analyses of Drosophila species suggest that the X chromosome presents an unfavourable environment for the expression of genes in the male germline. A previous study in D. melanogaster used a reporter gene driven by a testis-specific promoter to show that expression was greatly reduced when the gene was inserted onto the X chromosome as compared with the autosomes. However, a limitation of this study was that only the expression regulated by a single, autosomal-derived...
Data from: Haplotype structure, adaptive history and associations with exploratory behaviour of the DRD4 gene region in four great tit (Parus major) populationsJakob C. Mueller, Peter Korsten, Christine Hermannstädter, Thomas Feulner, Niels J. Dingemanse, Erik Matthysen, Kees Van Oers, Thijs Van Overveld, Samantha C. Patrick, John L. Quinn, Matthias Riemenschneider, Joost M. Tinbergen, Bart Kempenaers & Christine Hermannstaedter
The assessment of genetic architecture and selection history in genes for behavioural traits is fundamental to our understanding of how these traits evolve. The dopamine receptor D4 (DRD4) gene is a prime candidate for explaining genetic variation in novelty seeking behaviour, a commonly assayed personality trait in animals. Previously we showed that a single nucleotide polymorphism in exon 3 of this gene is associated with exploratory behaviour in at least one of four Western European...
