Abstract Variation in the availability and distribution of food resources is a strong selective pressure on wild primates. We explored variation Tibetan macaque gut microbiota composition during winter spring seasons. Our results showed that microbial diversity varied by season. In winter, genus Succinivibrio , which promotes digestion cellulose hemicellulose, was significantly increased. spring, abundance Prevotella associated with carbohydrates simple sugars, PICRUSt analysis revealed...
Primates spend a significant proportion of their lives at sleeping sites: the selection secure and stable tree can be crucial for individual survival fitness. We measured key characteristics all species in which agile gibbons slept, including exposure crown, root system, height, presence food. Gibbons most frequently slept Dipterocarpaceae Fabaceae trees preferentially chose taller than average, above mean canopy height showed preference liana-free trees. These choices could reflect...
There is a vast and ever-accumulating amount of behavioural data on individually recognised animals, an incredible resource to shed light the ecological evolutionary drivers variation in animal behaviour. Yet, full potential such lies comparative research across taxa with distinct life histories ecologies. Substantial challenges impede systematic comparisons, one which lack persistent, accessible standardised databases. Big-team approaches building databases offer solution facilitating...
Recent studies highlight that the gut mycobiota play essential roles in mammalian metabolic and immune systems, but to date we lack information on forces naturally shape of wild primates. To investigate contributions host environmental factors taxonomic variation mycobiota, examined effects age, sex, season fecal wild‐living Tibetan macaques ( Macaca thibetana ). Using next generation sequencing a longitudinal set samples collected over 1 year, identified core fungal taxa present macaque's...
Ecotourism is a growing sector of the tourism industry, but few studies to date have quantified its impacts on local people, tourists and wildlife. We present preliminary study threat affiliative behaviors two groups free-ranging Tibetan macaques (Macaca thibetana) as function habituation tourist presence. Data indicate that less habituated group spent time within sight compared with more group. The engaged in frequent while humans, whereas behavior was not observed general pattern threats...
Previous research on Tibetan macaques (Macaca thibetana) at Mt. Huangshan, China, suggested that ecotourism can have detrimental consequences. This study identified sequences of behaviors typically occur in macaque-tourist interactions to examine whether particular tourist precipitate monkey responses. Focal sampling was used record relevant from tourists and 10 over 28 data collection sessions August 2006. Data collectors recorded each behavior occurred as part a sequence. Sequences were...
Research on leadership is a critical step for understanding collective decision making. However, only 4 of the 22 extant macaque species have been examined impact social rank and affiliation initiation movement. It far from clear whether such exists and, if so, how it works among other macaques. To answer these questions, we investigated free‐ranging, Tibetan macaques’ ( Macaca thibetana ) group departures provisioning area tested two alternative hypotheses: personal versus distributed...
Abstract To further the potential for applied personality studies, we present a methodology assessing in nonhuman animals without priori assumptions, using behavioral measures to discriminate survey results. Our study group consisted of 12 free-ranging, provisioned, adult Tibetan macaques Macaca thibetana at Valley Wild Monkeys, China. We asked familiar Chinese park guards and scientists rate each 27-item surveys. also recorded observations (> 100 hrs) from August–September, 2012. The...
Tourism is a common component of management practices directed toward endangered species and habitats, but few studies have explored the potential stressors that may occur to nonhumans as objects tourism. We examined impact tourists on provisioned, habituated Tibetan macaques (Macaca thibetana). Data were collected during August 2005 at Valley Wild Monkeys (VWM), Mt. Huangshan, China. From tourist viewing platform, we measured densities, behaviors (for example, foot, hand, mouth noises;...
Although seasonal breeding has been documented in many non-human primates, it is not clear whether sexual behaviors show variation among male individuals. To test this hypothesis, the focal animal sampling method and continuous recording were used to investigate synchronization of five Tibetan macaques (Macaca thibetana) at Mt. Huangshan from Oct 2005 Sept 2006. Both copulatory sexually motivated (i.e., chase, grimace, sexual-inspection), which significantly higher mating season than...
Cryptic and endangered fauna, including many primate taxa, pose challenges for noninvasive collection of biomaterials. As a result, application genotyping to primates has been limited the use samples such as feces hair extraction PCR ‐amplifiable DNA . We present method saliva from habituated, free‐ranging monkeys. The utilizes low‐cost apparatus that controls contamination is usable with individual, primates. Saliva were collected 18 individuals in population T ibetan macaques ( M acaca...
Theoretical definitions of dominance, how dominance is structured and organized in nature, measured have varied as investigators seek to classify organize social systems gregarious species. Given the variability behavioral measures statistical methods used derive rankings, we conducted a comparative analysis using existing techniques analyze ranks, context-dependent structures, reliability analyses, rank predictability structures on other behaviors. We investigated these topics data from...
Play behaviors and signals during playful interactions with juvenile conspecifics are important for both the social cognitive development of young animals. The organization a species can also influence play. We examined relationships among play behaviors, candidate signals, bout termination in Tibetan macaques (Macaca thibetana) infant to characterize style. As despotic live groups strict linear dominance hierarchies infrequent reconciliation, we predicted that would be at risk...
Adult male Tibetan (Macaca thibetana), Barbary (M. sylvanus), and stump-tailed macaques arctoides) engage in bridging, a ritualized infant-handling behavior. Previous researchers found bias toward the use of infants for this behavior, but its function is debated. Explanations include three hypotheses: paternal care, mating effort, agonistic buffering. We studied group habituated, provisioned to test whether adult males' affiliative relationships with females predicted their an infant...
Vocal repertoires are basic and essential components for describing vocal communication in animals. Studying the entire suite of signals aids investigations on variation acoustic structure across social contexts, comparisons complexity systems taxa, exploration evolutionary origins species‐specific vocalizations. Here, we describe repertoire largest species macaque genus, Macaca thibetana . We extracted thirty parameters from call recordings. Post hoc validation through quantitative analyses...
Previous studies have reported the negative impacts of tourism on nonhuman primates (NHPs) and tourists advocated improvement management, yet what constitutes good quality management remains unclear. We explored whether rates macaque aggression self-directed behaviors (SDBs) differed under supervision two park ranger teams at Valley Wild Monkeys (VWM) in Mt. Huangshan, Anhui Province, China. The provisioned managed a group macaques an alternating monthly basis. Monkey, tourist were collected...
Abstract Leadership is a key issue in the study of collective behavior social animals. Affiliation–leadership models predict that dyadic partner preferences based on grooming relationships or alliance formation positively affect an individual’s decision to follow support conspecific. In case many primate species, females without young infants are attracted mother–infant dyads. However, effects mother–infant–female associations affiliation–leadership remain less clear. free-ranging Tibetan...
