Temperature-Related Differences in Hair Cortisol Among Outdoor-Housed Rhesus Macaques (Macaca mulatta). [PDF]

Am J Primatol
ABSTRACT Temperature has a known potential to influence glucocorticoid concentrations obtained from fecal samples in nonhuman primates. Studies reliant on hair cortisol estimates obtained using samples from outdoor subjects, however, may not control for temperature. This omission is despite the general utility of hair as a sample matrix with relatively

Alternative reproductive tactics of unflanged and flanged male orangutans revisited

American Journal of Primatology, Volume 85, Issue 9, September 2023., 2023
Illustration of behavioral changes by individual male Bornean and Sumatran orang‐utans from the unflanged to the flanged morph (right). Pictures taken by A. Marzec, Suwi, C. Schuppli, G. Duvot (top left to bottom right) Abstract In many slowly developing mammal species, males reach sexual maturity well before they develop secondary sexual ...

Demographics and viability of an estuarine community of Indo‐Pacific bottlenose dolphins

Marine Mammal Science, Volume 39, Issue 1, Page 59-76, January 2023., 2023
Abstract Wildlife management requires reliable demographic information to assess the status of a population and its vulnerability to threats. This study calculated age class‐ and sex‐specific demographic parameters and assessed the viability of a community of Indo‐Pacific bottlenose dolphins (Tursiops aduncus) resident to the Peel‐Harvey Estuary in ...

Policing in nonhuman primates: partial interventions serve a prosocial conflict management function in rhesus macaques. [PDF]

, 2013
Studies of prosocial policing in nonhuman societies traditionally focus on impartial interventions because of an underlying assumption that partial support implies a direct benefit to the intervener, thereby negating the potential for being prosocial in ...

The role of great ape behavioral ecology in One Health: Implications for captive welfare and re‐habilitation success

American Journal of Primatology, Volume 84, Issue 4-5, May 2022., 2022
An illustration of some of the possible cascading outcomes of a single behavioral change in which an adult female orangutan spends more time than her wild counterparts on the ground. Abstract Behavior is the interface through which animals interact with their environments, and therefore has potentially cascading impacts on the health of individuals ...

Seasonal effects on reconciliation in Macaca Fuscata Yakui [PDF]

, 2006
Dietary composition may have profound effects on the activity budgets, levelof food competition, and social behavior of a species. Similarly, in seasonally breeding species, the mating season is a period in which competition for mating partners increases,

Mating skew in Barbary macaque males: the role of female mating synchrony, female behavior, and male–male coalitions [PDF]

, 2010
A fundamental question of sexual selection theory concerns the causes and consequences of reproductive skew among males. The priority of access (PoA) model (Altmann, Ann NY Acad Sci 102:338–435, 1962) has been the most influential framework in ...

In search of animal normativity: a framework for studying social norms in non-human animals. [PDF]

Biol Rev Camb Philos Soc
ABSTRACT Social norms – rules governing which behaviours are deemed appropriate or inappropriate within a given community – are typically taken to be uniquely human. Recently, this position has been challenged by a number of philosophers, cognitive scientists, and ethologists, who have suggested that social norms may also be found in certain non‐human ...

Grouping behavior of Sumatran orangutans (Pongo abelii) and Tapanuli orangutans (Pongo tapanuliensis) living in forest with low fruit abundance

American Journal of Primatology, Volume 82, Issue 5, May 2020., 2020
Average female party size of orangutans in Sumatran forest with low fruit abundance is more similar to average female party size of Bornean orangutans than to Sumatran orangutans living in forest with high fruit abundance. Abstract In contrast to the African great apes, orangutans (Pongo spp.) are semisolitary: Individuals are often on their own, but ...
