Consequences of different forms of conservation for large mammals in Tanzania: preliminary analyses

Aerial censuses revealed that mammal biomass per km2 was highest in National Parks. Densities of nine ungulate species were significantly higher in National Parks and Game Reserves than in areas that permitted […]
Elephant-induced structural changes in the vegetation and habitat selection by large herbivores in an African savanna

We studied how changes in the vegetation caused by elephants influence the […]
