Edge effects and large mammal distributions in a national park

While protected areas are a centrepiece of conservation, populations of animals in protected areas can still be subject to considerable human influence. Conservation theory suggests that many species should live at lower densities at the periphery of protected areas compared with the core area. Similarly, but more specifically, species subject to exploitation are expected to […]

Quantifying giraffe poaching as population threat

While it is difficult to quantify the real effects of poaching on giraffe populations, what is clear is that the bushmeat trade is thriving globally and it is highly likely that giraffe are affected by this trade. Rowcliffe et al. (2010) estimate that 273 tonnes of bushmeat is imported into Europe alone from Africa each […]

Changing Wildlife Populations in Nairobi National Park and Adjoining Athi-Kaputiei Plains: Collapse of the Migratory Wildebeest

There is mounting concern about declines in wildlife populations in many protected areas in Africa. Migratory ungulates are especially vulnerable to impacts of changing land use outside protected areas on their abundance. Range compression may compromise the capacity of migrants to cope with climatic variation, and accentuate both competitive interactions and predation. We analyzed the […]
