Data from: Cityscape genetics: structural vs. functional connectivity of an urban lizard population

Joscha Beninde, Stephan Feldmeier, Maike Werner, Daniel Peroverde, Ulrich Schulte, Axel Hochkirch & Michael Veith
Functional connectivity is essential for the long-term persistence of populations. However, many studies assess connectivity with a focus on structural connectivity only. Cityscapes, namely urban landscapes, are particularly dynamic and include numerous potential anthropogenic barriers to animal movements, such as roads, traffic or buildings. To assess and compare structural connectivity of habitats and functional connectivity of gene flow of an urban lizard, we here combined species distribution models (SDMs) with an individual-based landscape genetic optimization...

Data from: Climatic effects on population declines of a rare wetland species and the role of spatial and temporal isolation as barriers to hybridization

Katja Rohde, Yvonne Hau, Nicole Kranz, Jasmin Weinberger, Ortwin Elle & Axel Hochkirch
Climate change and climatic extremes may affect species directly or indirectly. While direct climatic effects have been intensively studied, indirect effects, such as increasing hybridization risk, are poorly understood. The goal of our study was to analyse the impact of climate on population dynamics of a rare habitat specialist, Chorthippus montanus, as well as the fine-scale spatial overlap with a sympatric habitat generalist, Chorthippus parallelus and the dispersion of hybrids. We were particularly interested in...
