Data from: Contrasting reproductive strategies of triploid hybrid males in vertebrate mating systems

Nicolas B. M. Pruvost, Peter Mikulíček, Lukáš Choleva & Heinz-Ulrich Reyer
The scarcity of parthenogenetic vertebrates is often attributed to their ‘inferior’ mode of clonal reproduction, which restricts them to self-reproduce their own genotype lineage and leaves little evolutionary potential with regard to speciation and evolution of sexual reproduction. Here, we show that for some taxa such uniformity does not hold. By using hybridogenetic water frogs (Pelophylax esculentus) as a model system, we demonstrate that triploid hybrid males from two geographic regions exhibit very different reproductive...

Data from: Gastrointestinal microbiota of wild and inbred individuals of two house mouse subspecies assessed using high throughput parallel pyrosequencing

Jakub Kreisinger, Dagmar Čížková & Jaroslav Piálek
The effects of gastrointestinal tract microbiota (GTM) on host physiology and health has been the subject of considerable interest in recent years. While a variety of captive bred species have been used in experiments, the extent to which GTM of captive and/or inbred individuals resembles natural composition and variation in wild populations is poorly understood. Using 454 pyrosequencing, we performed 16S rDNA GTM barcoding for 30 wild house mice (Mus musculus) and wild-derived inbred strain...

Data from: Zoogeography of epigean freshwater Amphipoda (Crustacea) in Romania: fragmented distributions and wide altitudinal variability

Denis Copilaș-Ciocianu, Michal Grabowski, Lucian Parvulescu & Adam Petrusek
Inland epigean freshwater amphipods of Romania are diverse and abundant for this region has a favourable geographical position between the Balkans and the Black Sea. Excluding Ponto-Caspian species originating in brackish waters and freshwater subterranean taxa, there are 11 formally recognized epigean freshwater species recorded from this country. They belong to 3 genera, each representing a different family: Gammarus (Gammaridae, 8 species or species complexes), Niphargus (Niphargidae, 2 epigean species) and Synurella (Crangonyctidae, one species)....

Data from: Squamate hatchling size and the evolutionary causes of negative offspring size allometry

Shai Meiri, Anat Feldman & Lukáš Kratochvil
Although fecundity selection is ubiquitous, in an overwhelming majority of animal lineages, small species produce smaller number of offspring per clutch. In this context, egg, hatchling and neonate sizes are absolutely larger, but smaller relative to adult body size in larger species. The evolutionary causes of this widespread phenomenon are not fully explored. The negative offspring size allometry can result from processes limiting maximal egg/offspring size forcing larger species to produce relatively smaller offspring (‘upper...

Data from: Local and regional founder effects in lake zooplankton persist after thousands of years despite high dispersal potential

Marc Ventura, Adam Petrusek, Alexandre Miró, Eva Hamrová, Danilo Buñay, Luc De Meester & Joachim Mergeay
We reconstructed the genetic structure of a planktonic crustacean Daphnia longispina living in high mountain lakes and ponds in the Pyrenees to investigate whether it was shaped by persistent founder effects originating shortly after the last glacial maximum or by ongoing dispersal and effective migration (gene flow). We found that the genetic structure can largely be explained by a single colonization event following gradual deglaciation of the Pyrenees c. 10-15 000 years ago. Nuclear genetic...

Data from: Determination of factors associated with natural soil suppressivity to potato common scab

Marketa Sagova-Mareckova, Ondrej Daniel, Marek Omelka, Vaclav Kristufek, Jiri Divis & Jan Kopecky
Common scab of potatoes is a disease, which is difficult to manage due to complex interactions of the pathogenic bacteria (Streptomyces spp.) with soil, microbial community and potato plants. In Bohemian-Moravian Highlands in the Czech Republic two sites (Vyklantice and Zdirec) were selected for a study of common scab disease suppressivity. At both sites, a field with low disease severity occurs next to one with high severity and the situation was regularly observed over four...
