The ecological impacts of lake ice loss in temperate lakes

Expanding our knowledge of winter limnology is critical for managing lakes , reservoirs, and all freshwater resources in a future with shorter winters and less lake ice. In temperate latitudes, we have largely ignored winter as a season that impacts ecological processes, and it is unclear what ramifications the loss of lake ice will have on lake ecosystems. This project will combine long-term observational datasets, high-frequency buoy data, and an experimental approach to understanding the role of light availability in under-ice productivity. 

Quantifying shifting fish migration phenology across the Great Lakes

The timing of major life cycle events (reproduction, flowering, feeding) is set by seasonal environmental cues in many organisms.  Migratory fish in the Great Lakes are largely spring spawners, and they move into tributary rivers as the water warms in March-June.  There is growing evidence that the timing of these migrations is shifting under climate change, creating ever-earlier migrations.  These changes in timing may profoundly change which species are present in rivers at a given time, potentially unraveling critical ecological linkages during the dynamic spring warming period.  We are
