Remote monitoring of primates using automated GPS technology in open habitats

Automated tracking using a satellite global position system (GPS) has major potential as a research tool in studies of primate ecology. However, implementation has been limited, at least partly because of technological difficulties associated with the dense forest habitat of many primates. In contrast, primates inhabiting relatively open environments may provide ideal subjects for use of GPS collars, yet no empirical tests have evaluated this proposition. Here, we used an automated GPS collar to record the locations, approximate body surface temperature, and activity for an adult female baboon during 90 days in the savannah habitat of Amboseli, Kenya. Given the GPS collar's impressive reliability, high spatial accuracy, other associated measurements, and low impact on the study animal, our results indicate the great potential of applying GPS technology to research on wild primates.
