Project Title: 
Interactions of arsenic and common elements in fresh water supplies.
Project Abstract: 
Ecologists have long acknowledged that biogeochemical cycles are strongly coupled and should not be examined in isolation. Multi-element studies are dramatically biased towards carbon, nitrogen, and phosphorus, while trace elements are usually neglected. Arsenic, a trace element that is relatively abundant and that can have detrimental human health effects, is closely associated with both carbon and phosphorus cycles. Therefore, the relative concentration of arsenic may have important implications for stream ecosystem functioning and nutrient fluxes, which I will examine by conducting a series of nutrient uptake experiments in streams with and without arsenic.
