Description

INTRODUCTION Understanding the impact of habitat heterogeneity upon natural populations is becomming more important as landscapes are increasingly fragmented (Hutchings et al., 2000; Turner et al., 2001). Resources, as well as habitats, have patchy distributions that may be likened to a cost-benefit surface comprised of patches of different quality (Pastor et al., 1997; Wiens, 2000; Fortin et al., 2002). Foraging paths through heterogeneous landscapes result from an interplay of foraging decisions with energetic and nutritional needs of the animal, dispersion of food plants and impact of abiotic disturbances (Pastor et al., 1997). Foraging paths, in turn, affect how an animal interacts with food, predators and mates (Bowne et al., 1999; McIntyre and Wiens, 1999; Brown, 2000).
