ALTITUDINAL GRADIENTS OF AQUATIC MACROINVERTEBRATE DIVERSITY IN THE CHOCO-ANDEAN REGION OF ECUADOR

The Choco bioregion is a biodiversity hotspot. However, the status of aquatic populations in this area is poorly understood. In Ecuador, the Andean-Choco area is one of the most modified regions due to deforestation. Environmental gradients and their relationships with aquatic communities are of major importance to understand how human activities affect rivers and the natural processes that sustain biodiversity in these streams. However, these aspects have not been studied in streams of these areas. Our objective was establish the macroinvertebrate diversity along an elevation gradient and the relationships of these with environmental variables in streams of the Ecuadorian Choco. We conducted our study at Mashpi Protected Forest in streams at 3 different altitudes: 1200, 800 and 600 m asl. We sampled all habitats of 3 streams at each altitude. We found both, a strong relationship of assemblages with habitat and strong altitudinal variations for several groups. Our findings show that composition and diversity of aquatic communities change from high and mid elevations to lower elevations. Currently the protected areas concentrate in higher, steeper areas of the basin leaving low gradient streams and its biodiversity out of protection.
