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 responsible for the variation in transfer rates among habitats and ecosystems. This theme largely follows the classic community ecology approach of quantifying energy flow through ecosystems, investigating interspecies interactions, and evaluating the demographic responses of species to various disturbances. As opposed to simply measuring contaminant trends in top predators, this ecological foundation provides a powerful framework in which to investigate the movement of contaminants through ecosystems that is explicitly based on how the ecosystems function. As such, results contribute to the body of knowledge regarding how ecological interactions contribute to contaminant cycling.
