Citizen science initiatives have been increasingly used by researchers as a source of occurrence data to model the distribution of alien species. Since citizen science presence‐only data suffer from some fundamental issues, efforts have been made to combine these data with those provided by scientifically structured surveys. Surprisingly, only a few studies proposing data integration evaluated the contribution of this process...

The Italian endemic voles belonging to the Microtus savii group (de Sélys‐Longchamps, 1838) include five controversial taxa, namely M. savii savii , M. s. niethammericus Contoli ; M. s. tolfetanus Contoli , M. s. nebrodensis ( Minà‐Palumbo, 1868) and M. brachycercus (Lehamann, 1961). A previous mt DNA phylogenetic analysis revealed three main mt DNA lineages that do not correspond to the recognized taxa. Here, we perform a com...

The red squirrel ( Sciurus vulgaris ) is a well‐known forest animal distributed all over Europe. Still, we are far from having a firm knowledge of the species’ phylogeography. This study investigates the genetic differentiation of S. vulgaris across the species’ Eurasian range, using sequence data from the mitochondrial DNA gene (D‐loop, 252 base pairs, cytochrome b , 359 base pairs), and eight variable autosomal microsatellit...
