Saving rodents, losing primates—Why we need tailored bushmeat management strategies
Efforts to curb the unsustainable wildlife trade in tropical forests conceptualize bushmeat as a generic resource, exploited by a homogeneous group. However, bushmeat is composed of miscellaneous species differing in risks of zoonotic disease transmissions, sensitivity to hunting and abundance. If people choose these species for varying reasons, mitigation approaches that neglect specific drivers would likely target abundant species, e.g. rodents…
Nocturnal activity in wild chimpanzees ( Pan troglodytes ): Evidence for flexible sleeping patterns and insights into human evolution
OBJECTIVES: We investigated occurrences and patterns of terrestrial nocturnal activity in wild chimpanzees (Pan troglodytes) and modelled the influence of various ecological predictors on nocturnal activity. METHODS: Data were extracted from terrestrial camera-trap footage and ecological surveys from 22 chimpanzee study sites participating in the Pan African Programme: The Cultured Chimpanzee. We described videos demonstrating nocturnal activity,…
Locating chimpanzee nests and identifying fruiting trees with an unmanned aerial vehicle
Monitoring of animal populations is essential for conservation management. Various techniques are available to assess spatiotemporal patterns of species distribution and abundance. Nest surveys are often used for monitoring great apes. Quickly developing technologies, including unmanned aerial vehicles (UAVs) can be used to complement these ground-based surveys, especially for covering large areas rapidly. Aerial surveys have been used successful…
Examining Landscape Factors Influencing Relative Distribution of Mosquito Genera and Frequency of Virus Infection
Mosquito-borne infections cause some of the most debilitating human diseases, including yellow fever and malaria, yet we lack an understanding of how disease risk scales with human-driven habitat changes. We present an approach to study variation in mosquito distribution and concomitant viral infections on the landscape level. In a pilot study we analyzed mosquito distribution along a 10-km transect of a West African rainforest area, which includ…
Estimating chimpanzee population size with nest counts: Validating methods in Taï National Park
Successful conservation and management of wild animals require reliable estimates of their population size. Ape surveys almost always rely on counts of sleeping nests, as the animals occur at low densities and visibility is low in tropical forests. The reliability of standing‐crop nest counts and marked‐nest counts, the most widely used methods, has not been tested on populations of known size. Therefore, the answer to the question of which metho…
Using Dung to Estimate Gorilla Density: Modeling Dung Production Rate
There is an urgent need for information on western gorilla population sizes and distribution to improve present and plan future conservation actions. Researchers traditionally have estimated gorilla densities on the basis of nest counts despite demonstrated variation in nest production and decay rates. The variation may lead to large biases in estimates of gorilla abundance. We investigated the use of an alternate index of gorilla abundance, via …
