摘要：

A spatially extended model of density-dependent discrete maps is presented. This model is based in the so-called coupled map lattice formalism and is applied to two well-known discrete models of population biology. Several new results are obtained, showing the importance of space on the qualitative properties of these models. Chaotic dynamics is more widely present in the spatially extended models than in the uncoupled counterpart but the presence of this behavior can be undistinguishable in real situations from a point attractor with added noise. Some general implications are also discussed. © 1992 Academic Press Limited All rights reserved.
