EcoLab serves as an interactive companion to two of our e-books, Conservation Biology and Applied Population Ecology.

RAMAS Landscape integrates the landscape model LANDIS with our RAMAS/GIS habitat-based metapopulation model. With the integration of a landscape and a metapopulation model, predictions about the viability, recovery, and growth of a species can be based on the predicted changes in the landscapes in which they live.

RAMAS Metapop is an interactive program that allows you to build models for species that live in multiple patches. It incorporates the spatial aspects of metapopulation dynamics, such as the configuration of the populations, dispersal and recolonization among patches and similarity of environmental patterns experienced by the populations. The program can be used to predict extinction risks and explore management options such as reserve design, translocations and reintroductions, and to assess human impact on fragmented populations. RAMAS Metapop is a powerful tool for population viability analysis (PVA).

Risk Calc makes new methods available for conducting distribution-free or nonparametric risk analyses. You decide what information or assumptions should be used, and the software calculates bounding estimates of risks. Often these bounds can be shown to be the best possible. Using Risk Calc, you can do quality assurance reviews for probabilistic risk and safety assessments. It supports probability bounds analysis, standard fuzzy arithmetic, and classicalinterval analysis. Its applications are like those of Monte Carlo packages such as @Risk or Crystal Ball, but Risk Calc does not require you to specify precise details of statistical distributions and their dependency relationships when empirical data are lacking.
