N2 - AimWe analysed the variation of species richness in the European freshwater faunaacross latitude. In particular, we compared latitudinal patterns in species richnessandß-diversity among species adapted to different habitat types.LocationEurope.MethodsWe compiled data on occurrence for 14,020 animal species across 25pre-defined biogeographical regions of European freshwaters from theLimnofaunaEuropaea. Furthermore, we extracted information on the habitat preferences ofspecies. We assigned species to three habitat types: species adapted to groundwater,lotic (running water) and lentic (standing water) habitats. We analysed latitudinalpatterns of species richness, the proportion of lentic species andß-diversity.ResultsOnly lentic species showed a significant species-area relationship. Wefound a monotonic decline of species richness with latitude for groundwater andlotic habitats, but a hump-shaped relationship for lentic habitats. The proportion oflentic species increased from southern to northern latitudes.ß-Diversity declinedfrom groundwater to lentic habitats and from southern to northern latitudes.Main conclusionsThe differences in the latitudinal variation of species richnessamong species adapted to different habitat types are in part due to differences in thepropensity for dispersal. Since lentic habitats are less persistent than lotic or groundwaterhabitats, lentic species evolved more efficient strategies for dispersal. Thedispersal propensity of lentic species facilitated the recolonization of central Europeafter the last glaciation. Overall, we stress the importance of considering the historyof regions and lineages as well as the ecological traits of species for understandingpatterns of biodiversity.
