Research: The Role of Sediment in the Food Web of an Andean Peidmont System
Species/Topic: fish, tadpoles and snails
|This project will investigate the role of sediment in the diets of fish, tadpoles, and snails in an Andean piedmont stream and determine the effect of sediment accumulation on primary productivity and microbial respiration on natural substrates. These approaches will give insight into the contribution of sediments to stream food webs and allow prediction of the impact of increasing anthropogenic sedimentation on primary consumers and ecosystem processes in tropical streams.
