We adopted a landscape-scale approach to analyze the genetic patterns (diversity, structure, and differentiation) of the Marbled White ( Melanargia galathea ). This butterfly species is characteristic of semi-dry grasslands, which have substantially declined in Switzerland during past decades. We sampled individuals on a regular grid of the established Biodiversity Monitoring program of Switzerland over five consecutive years,...

We present a conservation genetics tool kit, which offers two ready-to-use workflows for the routine application of genetic methods in conservation management. The workflows were optimized for work load and costs and are accompanied by an easy-to-read and richly illustrated manual with guidelines regarding sampling design, sampling of genetic material, necessary permits, laboratory methods, statistical analyses and documentati...

Epiphytes are strongly affected by the population dynamics of their host trees. Owing to the spatio‐temporal dynamics of host tree populations, substantial dispersal rates — corresponding to high levels of gene flow — are needed for populations to persist in a landscape. However, several epiphytic lichens have been suggested to be dispersal‐limited, which leads to the expectation of low gene flow at the landscape scale. Here,...
