Genetic diversity and Wolbachia infection of the Drosophila parasitoid Leptopilina clavipes in western Europe.

abstract：:We reanalysed published data to evaluate whether climate and habitat are barriers to dispersal in one of the most mobile and widely distributed mammals, the grey wolf (Canis lupus). Distance-based redundancy analysis (dbRDA) was used to examine the amount of variation in genetic distances that could be explained by an...
