Sierra Nevada Aquatic Research Laboratory

30 Jun, 11 AM - 01 Sep, 05 AM

I propose to carry out field work at montane lakes along an elevational gradient in Yosemite National Park, California, during a two-month summer field season from June 30 to September 1. At each lake or pond, I will measure temperature, water chemistry, nutrient ratios (C:N:P), DOC, chlorophyll content, and collect samples of phytoplankton which will be analyzed for size structure and stoichiometry. Additionally, I will measure zooplankton grazing rates in lakes to assess the degree of top-down control and whether the amount of grazing correlates with the nutritional content and size structure of phytoplankton. Phytoplankton biomass stability over time will also be measured at each lake over the course of the field season. Samples will be partially processed at Sierra Nevada Aquatic Research Laboratory (SNARL) where I will also be staying for the duration of my field season. Living phytoplankton samples will also be brought back to UCSD to establish populations for mesocosm and laboratory experiments.
