The importance of facilitation versus competition in structuring herbivore species
assemblages is a critical issue in theoretical ecology as well as for practical wildlife …

Primary productivity and herbivory were studied in the Serengeti National Park, Tanzania,

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 concept of nutrient limitation, as developed in agriculture, applies well to wild plants
grown under controlled conditions, although plants adapted to infertile soils are less …

The ecology of world vegetation is described in numer all of the drafting and photographic
work. They have ous books and journals, but these are usually very spe spent many hours …

Most ecosystems have multiple predator species that not only compete for shared prey, but
also pose direct threats to each other. These intraguild interactions are key drivers of …

The stable carbon and nitrogen isotope ratios of bone collagen have been used to trace diet
and habitat selection of the larger mammals of East Africa. 238 individuals of 43 species …

Three general hypotheses have been proposed to explain why many large herbivores have
highly aggregated patterns of distribution: dilution of predation risk, maintenance of forage in …

At a landscape scale, the combined influence of biotic and abiotic factors may determine the
distribution patterns of large herbivores in African savanna ecosystems. Herbivores foraging …

Published estimates of population densities of large savanna herbivores are used to relate
biomass to rainfall, and soil nutrient status as determined by geomorphology (after Bell …
