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.
It is specifically designed to measure the effects of contaminants on biological functioning across a gradient of ecological scales. Individual metrics vary depending on the specific taxa, ecosystems, and contaminants associated with each project, but the primary responses of interest can be categorized as: (1) Biochemical-level (e.g., stress biomarkers, cellular damage, endocrine response); (2) Individual-level (e.g., behavior, growth, mortality); and (3) Population-level. Perhaps the most important component of this theme is the overarching goal of integrating the effects at all levels of organization to form a more cohesive understanding of the emergent responses to contaminant exposure. Specifically, the goal is to not only understand how various exposure regimes induce responses at discrete scales, but also how effects at one scale contribute those at other scales. Additionally, this theme seeks to understand how contaminant-induced effects interact with other ecological stressors (e.g., disease, climate, predation, nutrition, and other disturbances) to quantify the cumulative role that contaminants play on natural resources.
