Background We identified and classified damselfly (Zygoptera) and dragonfly (Anisoptera)
metacommunities in Brazilian Amazonia, relating species distribution patterns to known
biological gradients and biogeographical history. We expected a random distribution of both
Zygoptera and Anisoptera within interfluves. At the Amazonian scale, we expected
Anisoptera metacommunities to be randomly distributed due to their higher dispersal ability
and large environmental tolerance. In contrast, we expected Zygoptera communities to …
