A study of animal movement in the Hoanib River catchment, northwestern Namibia

Seasonal movements of domestic stock and wildlife were analysed across the Hoanib River catchment. Data were gathered by ground and aerial surveys and represent the seasonal movement of animals, rather than the total number of animals in the catchment area. Domestic stock movement and distribution did not vary substantially and appeared to be associated with the seasonal, spatial availability of water and grazing in different places, and with human settlements. There was an apparent movement of cattle out of the

Right on track? Performance of satellite telemetry in terrestrial wildlife research

Satellite telemetry is an increasingly utilized technology in wildlife research, and current devices can track individual animal movements at unprecedented spatial and temporal resolutions. However, as we enter the golden age of satellite telemetry, we need an in-depth understanding of the main technological, species-specific and environmental factors that determine the success and failure of satellite tracking devices across species and habitats. Here, we assess the relative influence of such factors on the ability of satellite telemetry units to provide the

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 population dynamics of 11 ungulate species within Kenya’s Nairobi National Park, and compared them to those in the adjoining Athi-Kaputiei Plains, where human settlements and
