Hydrogen isotopes reveal evidence of migration of Miniopterus schreibersii in Europe
Abstract Background The Schreiber’s bat, Miniopterus schreibersii, is adapted to long-distance flight, yet long distance movements have only been recorded sporadically using capture-mark-recapture. In this study, we used the hydrogen isotopic composition of 208 wing and 335 fur specimens from across the species' European range to test the hypothesis that the species migrates over long distances. Results After obtaining the hydrogen isotopic composition (δ2H) of each sample, we performed geographic assignment tests by comparing the δ2H of samples with the δ2H of sampling sites. We found that 95 bats out of 325 showed evidence of long-distance movement, based on the analysis of either fur or …

Overall (first) results of the ‘100 questions for biodiversity conservation in Mediterranean-type regions of the world’ initiative
Mediterranean-type ecosystems (MTEs), with their characteristic climate, occur in just five regions of the world: the Mediterranean Basin, the Cape Region of South Africa, Southwestern and South Australia, California, and central Chile. In spite of their small geographic area, they harbour a significant and exclusive proportion of the planet’s biodiversity. Biodiversity values in MTE are threatened by a range of factor including land use changes, overexploitation of natural resources, global climate changes, among others. Researchers have a key role in providing solutions for conserving biodiversity in face of these multiple stressors and socio-economic challenges. Under the scope of the So…
Priority questions for biodiversity conservation in the Mediterranean Basin
The Mediterranean Basin is considered one of the world’s biodiversity hotspots, harbouring particularly high species richness and endemicity of taxonomic groups such as plants. This hotspot is unique at the global scale, because it has a history of intense anthropogenic influences that dates back to thousands of years, and where the current high-levels of biodiversity have thus been able to coexist with humans for millennia. Despite this long history of coexistence, biodiversity in the Mediterranean Basin is at risk due to a number of old and new anthropogenic stressors, including fast land use changes, overexploitation of natural resources, and global climate change. To tackle these proble…
