CORE RESEARCH CAPABILITIES AND EXPERTISE

1. Population Dynamics: Our goal is to identify the factors that govern population dynamics. Emphasis is on an integrative approach, combining field and laboratory studies to provide data for mechanistic models of ecological and evolutionary dynamics. (Personnel, Products)

2. Ecohydraulics: Studies concentrate on factors influencing behavior and passage of migratory fishes in river environments, such as migratory motivation, attraction, repulsion, responses to hydraulic environments, and limits of swimming performance, especially with reference to upstream and downstream fish passage structures. Passage performance studies are conducted in the semi-controlled environment of the CAFL flume facility and in the field, both in existing fish passage facilities and in riverine environments. (Personnel, Products)

  • Fish passage technologies, performance, and protocols
  • Animal locomotion and energetics

3. Physiology: Research is focused on physiological changes that may limit fish populations, particularly those undergoing restoration or enhancement. We are particularly interested in how environmental change, both of 'natural' and 'human' origins, affects normal growth and development in anadromous fish. Because of threats to their survival in many rivers in the northeastern US, salmon, shad, blueback herring, alewives and sturgeon are the anadromous species of primary interest. (Personnel, Products)

  • Physiology and migration
  • Endocrine disruptors
  • Climate change
  • Acid rain

4. Toxicology: Research is focused on the fate and effects of contaminants in aquatic ecosystems, particularly effects on reproduction, adaptation to environmental contaminants, the effects of multiple stressors on survival, reproduction and physiological processes in fish, and the development of non-lethal contaminant biosensors. (Personnel, Products)

  • Non-lethal biosensors
  • Multiple stressors
  • Sediment contaminant mobilization and effects
  • Diadromous species restoration research network
  • Other research
