I investigate processes at the ecosystem level using statistical modelling. My main interest in research is to understand ecological processes and population dynamics of aquatic organisms at the ecosystem level, in particular those aspects that are relevant to resource management. Recently I have been investigating spatial and temporal scales needed to study the spatial distribution of fish abundance and obtain indices of abundance of fish populations in marine and freshwater ecosystems. Since fish, as other aquatic organisms, cannot be directly observed large scale population studies must rely on analysis of data from scientific surveys or commercial operations. The analysis of this information requires specialized statistical modeling. Currently my focus is in the Great Lakes.

Teaching emphasis is on the application of ecological knowledge to species conservation and ecosystem management. Research interests center on the influence of human activities on the condition of rivers and their watersheds, including the effects of land use on stream health, assessment of variation in flow regime, and estimation of nutrient loads and budgets. Additional, collaborative activities are directed at the translation of aquatic science into useful products for management, conservation, and restoration of running waters.

My teaching interests center around fish ecology, aquaculture, and environmental sciences. Current teaching includes a senior course on fish ecology, an introductory course on environmental sciences, and a seminar in aquaculture. My major research interest has focused on the energetics of fish. I am best known for my work on northern pike, which has elucidated the behavioral ecology and production of natural pike populations.

Teaching includes courses in fish ecology and fisheries science. Recent research includes exotic species impacts on aquatic food webs and predator-prey dynamics; understanding environmental factors influencing fish spawning, growth and survival; consequences of dam removal or altering hydropower operations for fish habitat and production; use of GIS to classify and map Great Lakes fish habitats; use of hydrodynamic circulation models and satellite imagery to understand effects of climate variability on advection and survival of fish eggs and larvae.

Research interests include the effects of natural and anthropogenic stresses on Great Lakes and marine ecosystems, with a focus on the use of models and integrated assessments in transferring knowledge to the decision-making process. Teaching interests include the roles of conveying uncertainty, peer review, stakeholder input, interpreting trends, prediction, scale, and government interaction in developing and applying Integrated Scientific Assessments.

Paul Webb holds a joint appointment with the Department of Ecology and Evolutionary Biology and he serves as Associate Director of the Program in the Environment. Teaching includes Ecological Issues, fish biology and ecology, animal physiology, and a number of undergraduate independent studies each year. Research includes physiological ecology and functional morphology of aquatic vertebrates, primarily fishes. Research seeks to identify and understand fundamental principles of energetics and form and function, which in turn affect distributions of fishes and their populations and assemblages. These interests are currently focussing on how physical factors shape shorelines and hence shoreline fish communities, affecting management and restoration. Another area of research concerns factors that affect fish assemblages in coastal marshes. Much of these researches are done in collaboration with faculty in the engineering school.

Teaching involves general aquatic and stream/river ecology. Research interests include ecology of rivers and lakes, watershed management, community dynamics and population regulation, trout stream food webs, behavioral adaptations of aquatic insects, fish invertebrate interactions, and fisheries management.

Steven Yaffee is the Theodore Roosevelt Professor of Ecosystem Management. Research involves natural resource and environmental policy, planning and management; processes of policy formation and implementation; and organizational arrangements for managing natural resources. Of particular interest is policy involving endangered species, public lands, ecosystem management, and nonprofit environmental organizations. Also interested in innovative ways to make collective choices including alternative dispute resolution, collaborative problem-solving, and negotiation processes.

Research interests focus on testing and enhancing human behavior, decision, and persuasion theories in environmental education and communication (especially risk) contexts applying structural equation modeling, meta-analysis and case studies. Most current studies focus on evaluating environmental education resources and programs.
