title: Data from: Integrating three comprehensive datasets shows that mitochondrial DNA variation is linked to species traits and paleogeographic events in European butterflies.

description: Understanding the dynamics of biodiversity, including the spatial
 distribution of genetic diversity, is critical for predicting responses to
 environmental changes, as well as for effective conservation measures.
 This task requires tracking changes in biodiversity at large spatial
 scales and correlating with species functional traits. We provide three
 comprehensive resources to understand the determinants for mitochondrial
 DNA differentiation represented by i) 15,609 COI sequences and ii) 14
 traits belonging to 307 butterfly species occurring in Western-Central
 Europe and iii) the first multi-locus phylogenetic tree of all European
 butterfly species. By applying phylogenetic regressions we show that
 mitochondrial DNA spatial differentiation (as measured with Gst,
 G'st, D and Dst) is negatively correlated with species traits
 determining dispersal capability and colonization ability. Thanks to the
 high spatial resolution of the COI data, we also provide the first
 zoogeographic regionalization maps based on intraspecific genetic
 variation. The overall pattern obtained by averaging the spatial
 differentiation of all Western-Central European butterflies shows that the
 paradigm of long-term glacial isolation followed by rapid pulses of
 post-glacial expansion has been a pervasive phenomenon in European
 butterflies. The results and the extensive datasets we provide here
 constitute the basis for genetically-informed conservation plans for a
 charismatic group in a continent where flying insects are under alarming
 decline.
