Abstract
A fairly realistic three-species food chain model based on the Leslie-Gower scheme is investigated by using tools borrowed from the nonlinear dynamica l systems theory. It is observed that two co-existing attractors may be gen erated by this ecological model. A type-I intermittency is characterized an d a homoclinic orbit is found. (C) 2001 Elsevier Science Ltd.
