The purpose of this study was to determine how the dam placed in the Quebrada Máquina, Monteverde, Costa Rica, affects the abundance, richness, and diversity of benthic macroinvertebrate communities. Samples were collected from 20 sites, 50m upstream and downstream of the dam. The relative percentage of streambed substrate composition was also documented at all test sites. There were significant decreases in Order richness and diversity as absolute distance from the dam decreased. In addition, the substrate composition was found to be homogeneous for sand directly upstream of the dam. This leads to the conclusion that the dam has created a buildup of sand, thereby decreasing richness and diversity, by means of destroying suitable habitat...
