Research

We work to better understand freshwater biological communities, ecosystem processes and services,
and natural resources management, often through quantifying ecological relationships. We focus on
lake ecology and stewardship, especially in holistically understanding and managing lake biological
communities and ecosystem services with state, local, and tribal partners. As an applied ecology lab, we
engage with a range of lake management challenges (e.g., water quality, aquatic invasive species, food
webs, and lake plant, zooplankton, and fish community ecology) as we work with partners to
understand and strengthen relationships between people and lakes.
