Anthropogenic stressors on aquatic ecosystems: Modeling links between UV radiation, geochemistry, bioaccumulation, and invertebrate communities at a landscape scale

Principal Investigators:

Marjorie L. Brooks

Multiple environmental stressors such as trace metal contaminants, increased ultraviolet (UV) radiation, and climate warming are having synergistic effects on aquatic ecosystems. Abiotic effects propagate through all levels of ecosystem organization, providing opportunities to develop the integrative models needed to assess and predict important interactive effects of multiple stressors. For example, when invertebrates bioaccumulate metals above thresholds beyond which some species cannot regulate metal intake, it leads to impaired growth, reproduction,... more
