Current Research

My research focuses on the effects of change on invertebrate ecology, food webs, organic matter dynamics, and nutrient cycling in freshwater ecosystems, particularly small streams which are most tightly linked to the terrestrial environment. My colleagues and I employ functional measures such as leaf and wood processing rates, secondary production, and diet analyses to assess ecosystem response to a variety of management practices over long time periods and large scales. Our current projects include:

  • Linking the complexity of terrestrial leaf inputs with stream ecosystem function
  • Examining faunal diversity in peatland watersheds at Marcell Experimental Forest
  • Comparing the capacity of forest streams for nutrient uptake in a high and low nitrogen ecosystem
  • Quantifying headwater stream food webs in the Salmon Trout River, home to a threatened population of coaster brook trout
  • Evaluating impacts of riparian timber harvesting on aquatic organisms and habitat

Why This Research is Important

Water quality and quantity has become a critical issue for a growing population. Properly managed forests provide a variety of goods and services including clean water for people and wildlife. Small streams, tightly linked to forests and the larger river network, are often overlooked components of the landscape. Understanding the functional responses of stream ecosystems to local and global changes are key to better management decisions and the protection, maintenance, or restoration of the ecosystem services they provide.
