Data from: Temporal migration pattern and mating tactics influence size-assortative mating in Rana temporariaCarolin Dittrich, Ariel Rodríguez, Ori Segev, Sanja Drakulić, Heike Feldhaar, Miguel Vences & Mark-Oliver Rödel
Assortative mating is a common pattern in sexually reproducing species, but the mechanisms leading to assortment remain poorly understood. By using the European common frog (Rana temporaria) as a model, we aim to understand the mechanisms leading to size-assortative mating in amphibians. With data from natural populations collected over several years, we first show a consistent pattern of size-assortative mating across our two study populations. We subsequently ask if assortative mating may be explained by...
Data from: Comparison of photo-matching algorithms commonly used for photographic capture-recapture studiesMaximilian Matthé, Marco Sannolo, Kristopher Winiarski, Annemarieke Spitzen-Van Der Sluijs, Daniel Goedbloed, Sebastian Steinfartz & Ulrich Stachow
Photographic capture–recapture is a valuable tool for obtaining demographic information on wildlife populations due to its noninvasive nature and cost-effectiveness. Recently, several computer-aided photo-matching algorithms have been developed to more efficiently match images of unique individuals in databases with thousands of images. However, the identification accuracy of these algorithms can severely bias estimates of vital rates and population size. Therefore, it is important to understand the performance and limitations of state-of-the-art photo-matching algorithms prior to...
Animals have evolved different defensive strategies to survive predation, among which chemical defences are particularly widespread and diverse. Here we investigate the function of chemical defence diversity, hypothesising that such diversity has evolved as a response to multiple enemies. The aposematic wood tiger moth (Arctia plantaginis) displays conspicuous hindwing colouration and secretes two distinct defensive fluids, from their thoracic glands and abdomen. We presented fluids from lab-reared moths to two biologically relevant predators, birds and...
Phylogenomics is extremely powerful but introduces new challenges as no agreement exists on “standards” for data selection, curation and tree inference. We use jawed vertebrates (Gnathostomata) as model to address these issues. Despite considerable efforts in resolving their evolutionary history and macroevolution, few studies have included a full phylogenetic diversity of gnathostomes and some relationships remain controversial. We tested a novel bioinformatic pipeline to assemble large and accurate phylogenomic datasets from RNA sequencing and find...
Data from: Breeding bird species diversity across gradients of land use from forest to agriculture in EuropeMatti J. Koivula, Dan E. Chamberlain, Robert J. Fuller, Stephen C. F.

Loss, fragmentation and decreasing quality of habitats have been proposed as major threats to biodiversity world-wide, but relatively little is known about biodiversity responses to multiple pressures, particularly at very large spatial scales. We evaluated the relative contributions of four landscape variables (habitat cover, diversity, fragmentation and productivity) in determining different components of avian diversity across Europe. We sampled breeding birds in multiple 1-km2 landscapes, from high forest cover to intensive agricultural land, in eight...
