Scale-dependent resource use in the Euphydryas aurinia complex

Butterflies of the European Euphydryas aurinia complex include a series of taxa, showing morphological and eco-ethological differences. All of them are threatened by changes in land use affecting both the structural and functional connectivity of habitat patches, as well as habitat quality. In this framework, we analysed the use of resources by two of the three taxa occurring in Italy, E. (a.) glaciegenita (Alpine) and E. (a.) provincialis...
