Large‐scale biodiversity databases have great potential for quantifying long‐term trends of species, but they also bring many methodological challenges. Spatial bias species occurrence records is well recognized. Yet, the dynamic nature this spatial – how has changed over time been largely overlooked. We examined within multiple in Germany and tested whether relation to land cover or use (urban protected areas) time. focused our analyses on urban areas as these represent two well‐known...
Over the last decades, worldwide decline of amphibian populations has become a major concern researchers and conservationists. Studies have reported diversity trends, with some species strongly declining, others remaining stable still increasing. However, only few been monitored annually for long period time by specific monitoring programmes. Instead, there are many heterogeneous datasets that contain observations amphibians from professional surveys as well diverse citizen science other...
Abstract Hybridization is a major evolutionary process with significant consequences for the ecology and conservation of species lineages. However, genetic studies that evaluate level influence hybridization in wild populations concern remain scarce, despite recognition unaddressed can bias results lead to erroneous conclusions. Here, we explore how mixed natterjack ( Epidalea calamita ) green toads Bufotes viridis impacts estimation parameters used status regionally threatened toad. In...
The European spurge hawkmoth, Hyles euphorbiae (Lepidoptera, Sphingidae), has been intensively studied as a model organism for insect chemical ecology, cold hardiness and evolution of species delineation. To understand isolation mechanisms at molecular level, this study aims determining genetic factors underlying two adaptive ecological trait candidates, phorbol ester (TPA) detoxification seasonal acclimation. A draft transcriptome H. was generated using Illumina sequencing, providing the...
The unique nomadic life-history pattern of army ants (army ant adaptive syndrome), including obligate colony fission and strongly male-biased sex-ratios, makes prone to heavily reduced effective population sizes (Ne). Excessive multiple mating by queens (polyandry) has been suggested compensate these negative effects increasing genetic variance in colonies populations. However, the combined evolutionary consequences polyandry life history on structure have only studied a few selected...
Abstract Sex‐biased dispersal is a widespread phenomenon in the animal kingdom, which strongly influences gene flow and population structure. Particularly army ants, important key‐stone predators tropical ecosystems, are prone to fragmentation isolation due their extraordinary mating system: queens permanently wingless, propagate via colony fission, only males disperse flights. Here we report on sex‐biased genetic structure of an African subterranean ant, Dorylus ( Typhlopone ) fulvus ....
Animals often exhibit particular ‘personalities’, i.e. their behaviour is correlated across different situations. Recent studies suggest that this limitation of behavioural plasticity may be adaptive, since continuous adjustment one's time-consuming and costly. In social insects, particularly aggressive workers might efficiently take over fighting in the contexts both nest defence ‘policing’, regulation kin conflict society. Here, we examine whether who engage policing ant Platythyrea...
The spurge hawkmoth Hyles euphorbiae L. (Sphingidae) comprises a remarkable species complex with still not fully resolved taxonomy. Its extensive natural distribution range covers diverse climatic zones. This predestinates particular populations to cope different local seasonally unfavorable environmental conditions. ability of the pupae overcome outer frosty conditions is well known. However, differences between two main ecotypes (‘euphorbiae’ and ‘tithymali’) in terms inherent degree frost...
