Climate change predicts hotter, drier conditions across southern Africa, meaning fewer forage and water resources. Antelopes need to balance their energetic and metabolic needs within a patchy landscape, coping with spatial and temporal variation in resource availability and risk. We studied 4 species with varying levels of water dependency: red lechwe, waterbuck, tsessebe and eland, in the Zambezi region of Namibia. 10 adult females of each species were fitted with GPS collars mounted with audiologgers, high resolution triaxial accelerometers and black globe temperature sensors, and they were implanted with core and subcutaneous body temperature loggers; heart rate loggers; and activity sensors. A large amount of data was generated and will be analysed to identify physiological and behavioural responses to changing environmental conditions, which can then be extrapolated to predict vulnerability to climate change.
