Selenium in Ecosystems: Bay-Delta Ecosystem Scale Selenium Model

The Bay-Delta Ecosystem-Scale Selenium Model illustrates five interconnected modules that depict essential aspects of the Bay-Delta's hydrology, biochemistry, and ecology and of the exposure and ecotoxicology of predators at risk from Se. These modules, and the detailed sub-models that also were developed, conceptualize and quantify (1) how Se is processed from water through diet to predators and (2) its effects on ecosystems. The outcomes of modeled scenarios also are given.
