Odonata diversity and composition associated with different conditions in riparian vegetation along a stream located in Colombia. Actu Biol [online]. 2020, vol.42, n.113, e2.  Epub 10-Maio-2021.

The fragmentation of aquatic and riparian environments has damaged diversity into ecosystems. These injuries are pronounced in areas as tropical dry forests in Colombia, which are endangered zones that could be disappear in few years. In this situation, diversity and composition in Odonata insects, which are influenced by abiotic factors, could be excellent tools for understanding environmental status. Thus, we aim to observe changes in Odonata diversity and composition in different riparian vegetation during a year, along a stream from a remnant of dry forest. At the same time, we hypothesize that there are differences in Odonata diversity and composition. To take this, we sampled Odonata, larvae and adults, and environmental variables in four sampling stations, with different riparian vegetation during a year. We collected a total of 272 specimens corresponding to 16 species. In one hand, we noted variations in Odonata composition, showed in species records and similarity index. In other hand, we do not observe differences in Odonata diversity. Lastly, we approve in part our hypothesis exposing only Odonata composition changes with riparian vegetation, during sampling year.
