AQUATIC MACROINVERTEBRATES AS BIOINDICATORS OF WATER QUALITY IN RURAL AND URBAN STREAMS AFFECTED BY CHANNELIZATION.
Two traditional biomonitoring metrics, used to infer organic pollution in freshwater, were adapted for Puerto Rico: BMWP (Biological Monitoring Working Party) and FBI (Family Biotic Index). On the other hand, Urban stream syndrome studies, which are focused on the effect of channelization structures on water quality and macroinvertebrate diversity, demonstrated that the presence of bridges and culverts splits streams into three sections (upstream of the bridge, channelized section and downstream of the bridge) and changes aquatic macroinvertebrates abundance and richness in every section. Because BMWP'PR and FBI'PR relies on abundance and richness (both affected by channelization structures) to indicate water quality, this project aims to determine whether water quality is affected by the presence of channelization structures in streams. To answer this question, macroinvertebrate diversity was studied in two streams with culverts and with contrasting water qualities: Quebrada Infierno (Urban), and Quebrada Grande (Rural). Abundance and richness were used to calculate BMWP'PR and FBI'PR. Results showed that the presence of culverts affected water quality in rural and urban streams in a similar manner by creating gradients of water quality, with largest changes occurring in polluted urbanized streams.
