Phylogenetic niche conservatism explains an inverse latitudinal diversity gradient in freshwater arthropods
The underlying mechanisms responsible for the general increase in species richness from temperate regions to the tropics remain equivocal. Many hypotheses have been proposed to explain this astonishing pattern but additional empirical studies are needed to shed light on the drivers at work. Here we...
