Consequences of species range shiftsExpansions of species distributions upslope and poleward are among the most commonly reported outcomes of climate change. Our research is exploring the ecosystem and community outcomes of these range shifts.

Community ecology of ecotonesEcosystem boundaries are fuzzy, and the transitional zones that connect adjacent ecosystems are fascinating and understudied. We are studying tidal freshwater wetlands and river-side rock pools to understand how communities respond to temporal variation in these ecotonal habitats.

Balancing the ecology and economies of forested watershedsForests and freshwaters are tightly coupled ecologically and through their natural resource economies. Our interdisciplinary team is exploring the effectiveness of riparian management for balancing forest harvest with the ecological integrity of freshwaters.

Juvenile Atlantic salmon in Maine's changing riversEndangered Atlantic salmon are iconic to Maine and it's cool, clear rivers. We are studying how climate change stressors alter the ability of juvenile salmon to compete with Smallmouth Bass and other freshwater predators.

Community responses to disturbanceAlmost all communities are subject to disturbances at some point in time or space. Our research in streams and wetlands is exploring how communities recover from flood and drying disturbances and how spatial variation in disturbance regimes influence communities and their food webs.

Effects of habitat size on food webs The spatial dimensions of a habitat is among its most fundamental properties. Our group is collaborating with researchers from New Zealand and Australia to examine how habitat size influences stream food-web structure and stability.
