Current Research

My research deals with the relationship between land use, aquatic habitat, and the distribution and abundance of fish and aquatic invertebrates. Specializing in establishing explicit, mechanistic links between environmental variation with behavior, growth, and survival, I am particularly interested in using basic science to assist restoration, conservation, and management.

  • Bioenergetics approaches to habitat suitability modeling for juvenile salmonids
  • Effects of forest change on aquatic habitats, invertebrates, and fishes
  • Using genetic and stable isotope markers to understand Atlantic salmon movement and dispersal between habitats
  • Role of biotic interactions at local spatial scales in determining growth and survival of juvenile salmonids
  • Role of anadromous fish in the transport of nutrients and materials to and from freshwater ecosystems
  • Effects of hydrologic alteration on river and floodplain ecosystems
  • Effects of acidification on Atlantic salmon

Research Interests

  • Develop and apply new techniques and technologies to determine the effects of fragmentation associated with dams and roads on brook trout and other native species.
  • Develop an adaptive management framework to implement and assess ecologically sustainable flow regimes for notheastern river systems.
  • Determine the relationship between long-term changes in forest structure and atmospheric emissions and aquatic ecosystems and communities.
  • Understand the role of habitat-dependent interactions between invasive and native species in structuring aquatic communities.

Why This Research is Important

Freshwater ecosystems in New England and the northeastern US are strongly influenced by past and present anthropogenic change. In order for managers and stakeholders to make decisions based on sound science, we need to understand the links between land use change, freshwater ecosystems and sustainable fish populations, and effectively communicate this knowledge.

National Research Highlights

As an engaged network, our urban field stations are national and international assets. Morgan Grove, U.S. Department of Agriculture Forest Service.

IITF and NRS each established a Charter for Urban Field Stations and Networks

Year: 2016

IITF and NRS officially established charters for Urban Research Stations in San Juan, Puerto Rico and Baltimore, Chicago, New York City, and Philadelphia to develop and deliver knowledge that contributes to the understanding of urban social-ecological systems and the adaptation of practices that lead to sustainable, resilient, equitable, and healthy urban environments. The charters formalized long-standing field station investments.

Scientist Refines Models Relating River Flows to Fish Habitat and Population Dynamics

Year: 2012

To generate robust preductions, models need to acknowledge the complex life histories of riverine and diadromous fishes
