Global species richness of dragonflies and damselflies (Odonata): latitudinal trends and insular colonization [PDF]

open access: yesPeerJ
Odonates are mainly “sun lover” insects, and therefore reach maximum diversity in tropical regions, particularly in rainforests. Here, worldwide patterns of species richness of the order are analysed, by compiling a database of species numbers for 255 ...
