What is it about?
One of the current concerns in aquatic ecology is to identify environmental factors (ie, physical habitat or water quality) that condition the spatial distribution of aquatic communities. One way to understand the environmental processes that control the structure and behavior of aquatic communities is through the analysis in quasi-pristine ecosystems.

Why is it important?
We conducted 19 sampling campaigns over a period of 35 months in four sections of the river. Biotic samples were selected in the periods with greater stability of the flow. In parallel to each sampling, 37 environmental variables grouped into three factors (riverbank corridor, hydromorphology and water quality) were recorded. This work, through the analysis of different factors mentioned above that operate at different scales, showed a clear influence of some variables (mean velocity, boulder substrate and water temperature) in the distribution of EFA aquatic communities.
Perspectives
We hope this article to contribute to the knowledge on the importance of microhabitat scale factors in the spatial distribution of aquatic communities in Andean stream.
