What is it about?
Several factors are important for species diversity in tropical forests. To study this we collect dragonflies in 172 streams in the Amazon, Brazil. We verified that the climate interacting with the biogeography (historical geographic distribution of the species) are what mold the diversity of dragonflies in the Amazon. In addition, we find that the species change along the great geographic extent of the Amazon.

Why is it important?
Climate change must negatively impact dragonflies. In addition, there are regions with many endemic species, occurring only in this region of the planet. This occurs in the region near the city of Belém, capital of the state of Pará, in the Brazilian Amazon, and this region is very degraded by man. Probably these dragonflies unique to this region will be extinct in a few years.
Perspectives
The diversity of the dragonflies of the Amazon should decrease in the long term due to the climatic changes and in the short term some region will lose species due to environmental degradation.
