Ramifying effects of the risk of predation on African multi-predator, multiprey large-mammal assemblages and the conservation implications

Impacts of predators on prey populations are incurred not only through mortality inflicted, but also from how the risk of mortality affects the behaviour, spatial distribution and resource access of potential prey species. This risk is governed by exposure to predators and vulnerability following encounters. Behavioural responses to reduce risks have ramifying consequences for habitat […]

Ecology of the giraffe in Tsavo East National Park, Kenya

The decrease in woody vegetation in Tsavo National Park has probably had adverse effects on woodland-adapted herbivores, including the giraffe (Girafa camelopardalis). In an ecological study we attempted to assess this species’ density, habitat preference and utilization, and population dynamics, using mainly road strip counts and identification of individual animals. Population structure varied seasonally and […]
