Data from: Informing conservation strategies with museum genomics: Long-term effects of past anthropogenic persecution on the elusive European wildcat
<p>Like many carnivore species, European wildcats (<em>Felis silvestris</em>) have suffered severe anthropogenic population declines in the past, resulting in a strong population bottleneck in the beginning of the 20th century. In Germany, the species has managed to survive its near-extinction in small isolated areas and is currently recolonizing former habitats owing to legal protection and concerted conservation efforts. Here, we SNP genotyped and mtDNA sequenced 56 historical and 650 contemporary samples to assess the impact of massive persecution on genetic diversity, population structure and hybridization dynamics of wildcats. Spatiotemporal analyses suggest that the presumed postglacial differentiation between two genetically distinct metapopulations in Germany is in fact the result of the anthropogenic bottleneck followed by re-expansion from few secluded refugia. We found that, despite the bottleneck, populations experienced no severe genetic erosion, nor suffered from elevated inbreeding or showed signs of increased hybridization with domestic cats. Our findings have significant implications for current wildcat conservation strategies, as the data analyses show that the two presently recognized wildcat population clusters should be treated as a single conservation unit. Although current populations appear under no imminent threat from genetic factors, fostering connectivity through the implementation of forest corridors will facilitate the preservation of genetic diversity and promote long-term viability. The present study documents how museum collections can be used as essential resource for assessing long-term anthropogenic effects on natural populations, e.g., regarding population structure and the delineation of appropriate conservation units, potentially informing todays' species conservation.</p>
Data for: Long-term changes in habitat selection and prey spectrum in a reintroduced Eurasian lynx (Lynx lynx) population in Switzerland
<p>When wild-caught Euan lynx (Lynx lynx) from the Slovak Carpathian Mountains were reintroduced to Central Switzerland in the early 1970s and spread through the north western Swiss Alps (NWA), they faced a largely unfamiliar landscape with strongly fragmented forests, high elevations and intense human land use. For more than 30 years, radiocollared lynx have been monitored during three different project periods (in the 1980s, 1990s and 2010s). Our study explored, how lynx over generations have learned to adjust to the alpine environment. We predicted that (1) lynx nowadays select more strongly for open habitats, higher elevations and steep slopes compared to the early stages of recolonization and that (2) consequently, there were significant changes in the Eurasian lynx' prey spectrum. To test our predictions, we analysed telemetry data (VHF, GPS) of 13 adult resident lynx in the NWA over 35 years, using Resource Selection Functions. Furthermore, we compared kills recorded from different individuals inhabiting the same region during three project periods. In general, lynx preferred forested areas, but over the years, they avoided open habitat less. Compared to the early stage of the recolonization, lynx in the most recent project period selected for higher elevations and the proportion of chamois in their prey spectrum surmounted that of roe deer. Potential driving factors for the observed changes could be increasing tolerance to human presence, intraspecific competition or fitness benefits through exploitation of new resources. Long-term studies like ours provide important insight into how animals can respond to sudden environmental changes e.g., in the course of translocations into new areas or anthropogenic alterations of their habitats.</p>
