It is well established that grooming underpins sociality in group-living primates, and a number of studies have documented the stress-reducing effects being groomed. In this study, we quantified behaviour physiological stress (assessed by faecal glucocorticoid analysis) free-ranging Barbary macaques, Macaca sylvanus. Our results indicate it giving rather than receiving associated with lower levels. These findings shed important new light on benefits key primate social life.
Background Recent work on non-human primates indicates that the allocation of social attention is mediated by characteristics attending animal, such as status and genotype, well value target to which directed. Studies humans indicate an individual’s emotion state also plays a crucial role in mediating their attention; for example, individuals look longer towards aggressive faces when they are feeling more anxious, this bias leads increased negative arousal distraction from other ongoing...
Abstract The measurement of ‘cognitive bias’ has recently emerged as a powerful tool for assessing animal welfare. Cognitive bias was initially, and widely, studied in humans, describes the way which particular emotions are associated with biases information processing. People suffering from clinical levels anxiety or depression, example, interpret ambiguous events more negatively than do non-anxious non-depressed people. Development methods use non-human animals revealed similar several...
The cognitive bias model of animal welfare assessment is informed by studies with humans demonstrating that the interaction between emotion and cognition can be detected using laboratory tasks. A limitation tasks amount training required animals prior to testing. potential solution use biologically relevant stimuli trigger innate emotional responses. Here; we develop a new method assess in rhesus macaques; paradigms used humans: Stroop; visual cueing and; particular; response slowing. In...
Abstract: The Neotropics house two guilds of large arboreal vertebrate seed predators: parrots and the pitheciin primates. Both have diets dominated by immature fruits. possibility members Pitheciinae (genera Cacajao , Chiropotes Pithecia ) acting as occasional dispersers has been mooted, but not experimentally shown. We combined primate behavioural data germination from three separate field studies in Brazilian states Amazonas Pará to analyse patterns post-consumption survivorship for seeds...
Neotropical monkeys of the genera Cacajao, Chiropotes, and Pithecia (Pitheciidae) are considered to be highly arboreal, spending most their time feeding traveling in upper canopy. Until now, use terrestrial substrates has not been analyzed detail this group. Here, we review frequency among pitheciin taxa determine ecological social conditions that might lead such behavior. We collated published unpublished data from 14 three genera. Data were gleaned 53 studies (including five on multiple...
We analyse the behaviour of Cacajao melanocephalus ouakary feeding at patches germinating seedlings in dried-out flooded forest. Seedlings Eschweilera tenuifolia (Lecythidaceae) were most commonly eaten (88.9%). Some seed revisited over several days, while others consistently ignored. tested 3 predictions relating uacari terrestrial foraging to: (1) arboreal escape route proximity, (2) patch size choice and (3) temporal patterns repeat exploitation. Comparison fed-at ignored revealed...
Feeding wildlife is a very popular tourist activity, largely because it facilitates the close observation of animals in their natural habitat. Such provisioning may benefit by improving survival and reproductive success, especially during periods food shortage. However, tourists also have negative impacts on health involved; to date such are poorly understood. Here, we investigated effects wild adult Barbary macaques, Macaca sylvanus, Morocco. We compared measures between heavily provisioned...
ABSTRACT Objectives Fruit husks are rarely uniformly hard, varying in penetrability via sulci and changes thickness. We tested whether a hard‐food specialist primate i) bites randomly on food fruit husk surfaces to access seeds, or ii) selects areas most easily penetrated by canines. consider this would occur so as minimize deployed mechanical force, energetic expenditure risk of dental breakage when feeding. Methods A sulcus is the natural line weakness where dehiscent breaks open. Using...
The amount of non-maternal care (allocare) found in primates varies greatly from species to species. Our paper examines this variation and focuses on possible reasons why mothers some anthropoid primate are prepared relinquish their infants other carers whereas others not. We use data collected the literature test a number hypotheses that attempt explain observed care. Analyses were carried out using comparative methods control for influence both body size phylogeny life-history ecological...
A possible function of laryngeal air sacs in apes and gibbons was investigated by examining the relationships between sac distribution, call rate, duration body weight a phylogenetic context. The results suggest that lack smaller humans is derived feature. Call parameters primates, such as rate duration, scaled to resting breathing (and therefore weight) only species without sacs, which appear modify these relationships. Apes larger may be able produce fast extended sequences risk...
