Proponents of optimal foraging theory attempt to predict the behavior of animals while they
are foraging; this theory is based on a number of assump-tions (133, 155, 210, 231). First, an …

We outline how principles of optimal foraging developed for diet and food patch selection
might be applied to movement behaviour expressed over larger spatial and temporal scales …

The largest land mammals are constrained in their activities by their large body size, a
theme that is emphasized in this account of their general ecology. The book begins by …

The gut capacity of mammalian herbivores increases linearly with body weight. This
relationship, coupled with the change in basal metabolism with weight, produces an MR/GC …

Grazing distribution patterns of large herbivores are affected by abiotic factors such as slope
and distance to water and by biotic factors such as forage quantity and quality. Abiotic …

A pplications of optimal forag-ing theory (Pyke 1984, Schoener 1971) to large herbivores
have been problematic (Owen-Smith and Novellie 1981, Westoby 1974), partly because …

The province of Jujuy lies in the northwestern corner of Argentina, abutting Chile and Bolivia
in the west and northeast, and ranging from 500 to 6,000 m in elevation. As a result of its …

A synthesis is given of the South African Savanna Biome project's 16 yr of research at the
Nylsvley site, aimed at predicting changes in the ecosystem's stability, induced by both …

Dugongs and manatees, the only fully aquatic herbivorous mammals, live in the coastal
waters, rivers and lakes of more than 80 subtropical and tropical countries. Symbols of fierce …

We present a handy mechanistic functional response model that realistically incorporates
handling (ie, attacking and eating) and digesting prey. We briefly review current functional …
