Some Demographic and Genetic Consequences of Environmental Heterogeneity for Biological Control
Economically important pests usually attack a crop or group of crops over a wide region in which there are geographic, local, and temporal variations in the environment. Effectiveness of any controlExpand
The Limiting Similarity, Convergence, and Divergence of Coexisting Species
1. There is a limit to the similarity (and hence to the number) of competing species which can coexist. The total number of species is proportional to the total range of the environment divided byExpand
Evolution in Changing Environments
The strategy of model building in population biology
what were previously independent clusters of more or less co herent theory. Population genetics and population ecology, the most mathematical areas of population biology, had developed with quiteExpand
Evolution in Changing Environments: Some Theoretical Explorations. (MPB-2)
Professor Levins, one of the leading explorers in the field of integrated population biology, considers the mutual interpenetration and joint evolution of organism and environment, occurring onExpand
The Island Syndrome in Rodent Populations
Populations of rodents isolated on islads often show systematic differences in demography, reproduction, behavior, and morphology when compared to mainland populations. These differences, termed theExpand

A model is developed for the coexistence and exclusion of species over a region of similar habitable patches. Since the balance of local extinction and colonization would leave some patchesExpand
The Dialectical Biologist

The precautionary principle in environmental science.
Environmental scientists play a key role in society's responses to environmental problems, and many of the studies they perform are intended ultimately to affect policy. The precautionary principle,Expand
