Mercury Cycling and Effects on Ecological Communities
Mercury contamination is a serious issue that impacts both ecosystem and human health on a global scale. In its organic (methylmercury) form, mercury is highly bioaccumulative and is among the most toxic compounds commonly found in the environment. Mercury is a relatively distinctive contaminant in the sense that the risk of deleterious environmental effects is more strongly related to ecological...
Aquatic Habitats and Communities
The Pacific Northwest includes a patchwork of public lands managed by numerous state and federal agencies. Our research informs and supports these agencies as they conserve and manage native amphibian species, including pre- and post-treatment assessment, decision support, long-term monitoring, population translocation, and habitat restoration.
Contaminant Bioaccumulation through Food Webs
This is a broad theme representing the largest component of the Contaminant Ecology Research Program, acting as a bridge between the “Habitat and Land Use Influences” and “Ecological Effects” themes. “Contaminant Bioaccumulation” focuses on quantifying the transfer or movement of contaminants through food webs, and identifying the primary landscape factors and ecological mechanisms that are...
Life Histories of Aquatic Species
Many species exhibit diverse behaviors that translate into different patterns of habitat use and demography. Diversity within species can be related to a complex array of processes, including genetic and maternal influences, and external environmental drivers. Our work addresses life history diversity in salmon and trout, including Pacific salmon, steelhead and rainbow trout, cutthroat trout, and...
Landscape Ecology of Aquatic Ecosystems
Landscape ecology has only a short history as a recognized discipline, but it has transformed our thinking about the interplay between pattern and process. We now understand that many smaller-scale phenomena are driven by spatial processes, such as the proximity of different habitats to one another, the ability of organisms to move through landscapes, and the dynamics of natural disturbance such...
