We investigated the effects of contemporary and historical factors on the
spatial variation of European dragonfly diversity. Specifically, we tested
to what extent patterns of endemism and phylogenetic diversity of European
dragonfly assemblages are structured by (i) phylogenetic conservatism of
thermal adaptations and (ii) differences in the ability of post-glacial
recolonization by species adapted to running waters (lotic) and still
waters (lentic). We investigated patterns of dragonfly diversity using
digital distribution maps and a phylogeny of 122 European dragonfly
species, which we constructed by combining taxonomic and molecular data.
We calculated total taxonomic distinctiveness and mean pairwise distances
across 4,192 50 km × 50 km equal-area grid cells as measures of
phylogenetic diversity. We compared species richness with corrected
weighted endemism and standardized effect sizes of mean pairwise distances
or residuals of total taxonomic distinctiveness to identify areas with
higher or lower phylogenetic diversity than expected by chance.
Broken-line regression was used to detect breakpoints in
diversity–latitude relationships. Dragonfly species richness peaked in
central Europe, whereas endemism and phylogenetic diversity decreased from
warm areas in the south-west to cold areas in the north-east and with an
increasing proportion of lentic species. Except for species richness, all
measures of diversity were consistently higher in formerly unglaciated
areas south of the 0°C isotherm during the Last Glacial Maximum than in
formerly glaciated areas. These results indicate that the distributions of
dragonfly species in Europe were shaped by both phylogenetic conservatism
of thermal adaptations and differences between lentic and lotic species in
the ability of post-glacial recolonization/dispersal in concert with the
climatic history of the continent. The complex diversity patterns of
European dragonflies provide an example of how integrating climatic and
evolutionary history with contemporary ecological data can improve our
understanding of the processes driving the geographical variation of
biological diversity.
Data_files_-_ECOG03137_Pinkert_et_al_2017Here we provide the
environmental, distributional and trait data used in Pinkert et al. 2017
(ECOG-03137), at both the species-level (for habitat preferences, i.e.
lentic/lotic) and aggregated at the assemblage-level. We also provide the
breakpoints from segmented regressions of the relationship between
latitude and four different measures of the diversity of European
dragonfly assemblages (species richness, corrected weighted endemism, the
residuals of total taxonomic distinctiveness against species richness and
standardized effect sizes of mean pairwise distances). For further
