Abstract

This paper analyses relationships among dispersal, spatial heterogeneity, and local ecological processes in the spruce budworm (Choristoneura fumiferana Clem.) - boreal forest system of eastern North America. A range of simulation and topological models are developed to reflect various hyotheses concerning those relationships. Model predictions are treated as guides to effective experimental design and efficient allocation of research priorities, rather than as ends in themselves. The analysis demonstrates the shortcomings of studies treating either dispersal or local processes alone, and argues instead for an integrated approach to spatial structure research in population ecology.
