We are ecologists based at the Sierra Nevada Aquatic Research Laboratory who study lakes in California’s Sierra Nevada mountains. Our objective is to conduct rigorous science to solve management challenges in this iconic mountain range. Our research focuses on a broad range of topics, and includes studies at the population, community, and ecosystem levels. To provide the information necessary for sound management decisions, we employ long-term capture-mark-recapture studies, whole-lake experiments, and large-scale lake surveys. Working closely with agency scientists, we use results from these studies to guide the development and implementation of lake restoration and amphibian conservation actions.
