Change in N and P Concentrations in Antarctic Streams as a Response to Change in Penguin Populations
ABSTRACT This study presents changes in the concentrations of nitrogen and phosphorus in two streams in Western Antarctica (Admiralty Bay, King George Island, South Shetlands) that differ in trophic status. The results suggest a decline in concentrations of the determined forms of N and P between 20...
