Behavioural and physiological responses of chacma baboons ( Papio ursinus ) to human‐induced mortality in anthropogenically modified habitat
As a result of expanding human populations and the anthropogenic modification of natural habitats, many wildlife populations are living in increasing proximity to humans. While this may provide benefits to some species through increased access to resources, sharing space and resources often leads to negative interactions or ‘conflict’ between humans and wildlife. In some cases, this conflict can result in permanent injuries or mortality of animal…
Estimating Abundance of Crop‐Foraging Primates in Anthropogenic Landscapes Using Camera Traps
As human populations grow, competition with wildlife increases, driving more frequent and intense negative interactions between humans and wildlife, of which crop foraging by primates like baboons ( Papio spp.) is a notable example. Farmers struggle to coexist with baboons, and are particularly concerned by their abundance, with more baboons resulting in more damage. Despite extensive primate research, there are few population estimates, particul…
On-primate Cameras Reveal Undocumented Foraging Behaviour and Interspecies Interactions in Chacma Baboons (Papio ursinus)
Historically, direct observation by human observers has been the primary method for studying primate behaviour. However, human observation may alter the behaviour of even habituated primates and that of other animals in their environment (LaBarge et al. , 2020 ). Observers may miss rare or subtle behaviours, particularly if maintaining recommended observation distances (Moll et al. , 2007 ). Remote methods, including on-animal cameras, can overco…
Seasonal variation in the behavioural ecology of samango monkeys (Cercopithecus albogularis schwarzi) in a southern latitude montane environment
Anthropogenic influences on primate antipredator behavior and implications for research and conservation
Predation risk affects prey species' behavior, even in the absence of a direct threat, but human‐induced environmental change may disturb ecologically significant predator–prey interactions. Here, we propose various ways in which knowledge of antipredator tactics, behavioral risk effects, and primate–predator interactions could assist in identifying human‐caused disruption to natural systems. Using behavior to evaluate primate responses to the on…
What have we been looking at? A call for consistency in studies of primate vigilance
Vigilance functions to detect threats. In primates, these threats emerge from both predators and conspecifics, but a host of other social, demographic, and ecological factors have been shown to influence primate vigilance patterns. The primate vigilance literature is thus characterized by considerable variation in findings, with inconsistent or contradictory results reported not only across different species but also within species and population…
Samango Monkeys (Cercopithecus albogularis labiatus) Manage Risk in a Highly Seasonal, Human-Modified Landscape in Amathole Mountains, South Africa
Wild species use habitats that vary in risk across space and time. This risk can derive from natural predators and also from direct and indirect human pressures. A starving forager will often take risks that a less hungry forager would not. At a highly seasonal and human-modified site, we predicted that arboreal samango monkeys ( Cercopithecus albogularis labiatus ) would show highly flexible, responsive, risk-sensitive foraging. We first determi…

Attribution to red suggests special role in dominance signalling
In many animals red is a signal of dominance and in humans there is evidence that red colouration may provide an advantage in sporting competition. This has been disputed by findings showing that colours other than red can also provide a competitive advantage. Here we examine basic perception of red versus blue in simple shapes by human judges to address the social signalling properties of red. We show that red is seen as more likely to win in ph…
Thermal constraints on activity scheduling and habitat choice in baboons
The importance of thermoregulation as a constraint on behavior has received comparatively little attention in relation to other ecological factors. Despite this, a number of studies suggested that high temperature may represent an important ecological constraint. This paper examines the impact of temperature on activity scheduling in a troop of chacma baboons ( Papio hamadryas ursinus ) at De Hoop Nature Reserve, South Africa. Once the daily, sea…

Clinal variation of maxillary sinus volume in Japanese macaques ( Macaca fuscata )
Macaques (genus Macaca ) are unique among cercopithecids in that they possess a maxillary sinus, and among anthropoids in that they demonstrate a relatively weak relationship between the size of this sinus and the cranium. To test the hypothesis that extrinsic factors may contribute to maxillary sinus size variation, a sample of 46 Japanese macaque ( M. fuscata ) crania from known localities were subjected to computed tomography (CT) imaging, and…
