Data from: Temperature and consumer type dependencies of energy flows in natural communities

Birgit Lang, Roswitha B. Ehnes, Ulrich Brose & Björn C. Rall
With the world continuously warming, a mechanistic understanding of how temperature affects interaction strengths, which are fundamental to food-web stability, is needed. As interaction strengths are determined by the flows of energy from resources to consumers, we investigated effects of temperature on animal energetics. We used newly compiled datasets on respiration rates and assimilation efficiencies to assess how temperature affects the energy use (respiration rates) and the efficiency of energy gain (assimilation efficiency) for different...

Data from: On the occurrence of three non-native cichlid species including the first record of a feral population of Pelmatolapia (Tilapia) mariae (Boulenger, 1899) in Europe

Thermally influenced freshwater systems provide suitable conditions for non-native species of tropical and subtropical origin to survive and form proliferating populations beyond their native ranges. In Germany, non-native convict cichlids (Amatitlania nigrofasciata) and tilapia (Oreochromis sp.) have established populations in the Gillbach, a small stream that receives warm water discharge from a local power plant. Here, we report on the discovery of spotted tilapia (Pelmatolapia mariae) in the Gillbach, the first record of a reproducing...

Data from: Cross-taxa generalities in the relationship between population abundance and ambient temperatures

Sell, Moritz Sonnewald, Stefan Stoll, Michael Türkay, Roel Van Klink, Oliver Schweiger, Rikjan Vermeulen & Katrin Boehning-Gaese
Identifying patterns in the effects of temperature on species' population abundances could help develop a general framework for predicting the consequences of climate change across different communities and realms. We used long-term population time series data from terrestrial, freshwater, and marine species communities within central Europe to compare the effects of temperature on abundance across a broad range of taxonomic groups. We asked whether there was an average relationship between temperatures in different seasons and...

Data from: Low rates of hybridization between European wildcats and domestic cats in a human-dominated landscape

Katharina Steyer, Annika Tiesmeyer, Violeta Muñoz-Fuentes & Carsten Nowak
Hybridization between wild species and their domestic congeners is considered a major concern for species conservation. Genetic integrity of the European wildcat, for instance, is of interest as the species is outnumbered by domestic cats by several orders of magnitude throughout its range. We genotyped 1071 individual wildcat samples obtained from hair traps and roadkills collected across the highly fragmented forests of western central Europe, in Germany and Luxembourg, to assess domestic cat introgression in...
