The effect of area size and predation on the time to extinction of prairie vole populations. simulation studies via SERDYCA: a Spatially-Explicit Individual-Based Model of Rodent Dynamics

Description: We present a spatially-explicit individual-based computational model of rodent dynamics, customized for the prairie vole species, M. Ochrogaster. The model is based on trophic relationships and represents important features such as territorial competition, mating behavior, density-dependent predation and dispersal out of the modeled spatial region. Vegetation growth and vole fecundity are dependent on climatic components. The results of simulations show that the model correctly predicts the ove… more

Cycling of /sup 36/Cl labeled DDT in natural systems. Technical progress report

Description: Data are reported on the cycling of /sup 36/Cl-labeled DDT in an old field ecosystem. Data are included on the content of DDT retained in samples of soil, plants, invertebrates, and tissues of small mammals. The body burden of DDT in both earthworms and slugs decreased during the six-year period whereas that of isopods increased, indicating that the food chain sources of the compound differ among soil invertebrates.
