Beta diversity should vary along major ecological gradients. We used data for 95 stream insect metacommunities to examine if beta diversity showed general patterns over the world. We did not find clear patterns along latitudinal, altitudinal or environmental gradients, suggesting that stochasticity typical of frequently-disturbed stream ecosystems may hinder finding clear patterns in stream insect beta diversity.
