Raptor Biology, Ecology, and Land-Use Effects

We study aspects of basic biology and ecology of predators to contribute to understanding ecosystems and to provide results that can be applied to the conservation of natural resources. Subject matter includes behavior and relationships of birds to features of their environment such as habitat, prey, and contaminants.

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...

Habitat and Land-Use Influences on Contaminant Bioaccumulation

The distribution and occurrence of contaminants and the associated biological exposure in ecological systems are driven by complex interactions between contaminant sources and mobilization pathways that are overlaid upon the habitat requirements of at-risk organisms. Moreover, landscape structure and land uses can strongly influence the driving processes of contaminant cycling, as well as the...

Ecological Effects of Contaminants

Whereas the other themes of the Contaminant Ecology Research Program focus on where, why, and how contaminants cycle and bioaccumulate in ecological systems, this theme is focused on determining what happens at environmentally relevant concentrations.

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...
