Responses of phytoplankton to varied resource availability in large lakes of the Greater Yellowstone Ecosystem
We assessed phytoplankton dynamics in three lakes in the Greater Yellowstone Ecosystem to better understand the connections between changing environmental conditions and aquatic communities. This work primarily describes the connections between resource availability and phytoplankton seasonal succes...
