Summary

Human activities in catchments have altered the quantity, composition and timing of nutrient inputs to streams.  Development of ecological response models for aquatic ecosystems is currently limited by a lack of knowledge about the impact of these changes on in-stream ecological and biogeochemical processes.

This aim of this project is to determine how changes in the type and concentrations of key constituents (primarily carbon and nitrogen) alter in-stream processes.  Main research question is:  "What impacts do changes in inputs of carbon and nitrogen (amount and type) have on in-stream cycling of these constituents and food web processes?"
