Sierra Nevada and Rocky Mountain national parks are experiencing among the highest rates of climate warming found globally, and have a long history of atmospheric nitrogen deposition.

Long-term research in Sequoia-Kings Canyon (SEKI) and Rocky Mountain (ROMO) National Parks has given us great insight into the effects of atmospheric deposition on lake biogeochemistry, productivity, and algal assemblages. Few studies, however, have yet addressed the interactive effects of changing climate and atmospheric nutrient deposition to these iconic features of our national parks.

This research will study the interactive effects of temperature and nutrients in regulating lake algal growth, and assess the extent of lake greening across both time and space in mountain lakes of the Rockies and Sierra Nevada.
