RAMAS® Ecosystem
DESCRIPTION
RAMAS® Ecosystem performs ecological risk assessments for food chain and food web models, linking bioassay results to population and community dynamics. RAMAS® Ecosystem imports data from standard laboratory bioassays, incorporates these data into the parameters of a population model, and performs a risk assessment by analyzing population-level differences between control and impacted samples. It facilitates the management of variability and uncertainty in data, expressing results as ecological risks.
