The role of herbivores in controlling plant species richness is a critical issue in the
conservation and management of grassland biodiversity. Numerous field experiments in …

Herbivores are regulated by predation under certain environmental conditions, whereas
under others they are limited by forage abundance and nutritional quality. Whether top-down …

Ecological niche differences are necessary for stable species coexistence but are often
difficult to discern. Models of dietary niche differentiation in large mammalian herbivores …

The remote sensing of pasture quality as determined by nitrogen, phosphorous, potassium,
