The manifestations and interdependence of social and physiological aging in wild female Assamese macaques (Macaca assamensis)
(2023-12-11)Aging is a multifaceted process which increases the probability of death, and although there can be only one outcome, the ways to get there are diverse. Accumulating evidence of aging in natural animal populations has shed ... -
Energetics in wild female Assamese macaques (Macaca assamensis): a behavioral and physiological approach
(2021-08-16)Energy is a key requirement of life. It is involved in life history traits such as body maintenance, growth and reproduction. Energy is a limiting resource and therefore has to be strategically allocated. When facing an ... -
The role of oxytocin, testosterone and cortisol in affiliation and bonding in male Barbary macaqaues
(2020-01-30)Many group living mammals minimize the costs of sociality by forming stable affiliative relationships, termed social bonds, with other group members. These bonds are highly adaptive as they increase fitness, and strongly ... -
Integrating behavior, hormones and genes associated with the primate HPA-axis
(2019-04-17)For zoologists, and especially primatologists, it has been a longstanding aim to decipher the causes of individual variability. Phenotypes associated with the hypothalamic-pituitary-adrenal (HPA)-axis, a central physiological ... -
The costs and benefits of sociality in semi-free ranging Barbary macaques (Macaca sylvanus)
(2019-03-04)Parasite infections are ubiquitous throughout the animal kingdom, and increased risk of parasite transmission has been suggested as one of the major costs of group living. With bigger group size and higher interaction ... -
Evolutionary origin of the human pair-bond – the adaptive significance of male-female relationships in wild Assamese macaques (Macaca assamensis), Thailand
(2017-08-02)The patterns of social interactions and the resulting relationships between members of a social group shape the social structure of animal societies. In large primate groups, both sexes potentially form differentiated ... -
Male social relationships among wild Assamese macaques (Macaca assamensis)
(2016-11-08)General socioecological theories predict that in multi-male multi-female mammalian groups, males and females compete over resources of different nature. While females mainly compete over generally sharable food, males ... -
Immature development in wild Assamese macaques (Macaca assamensis)
(2016-10-11)Relationships between adult attributes and lifetime fitness have been previously explored in numerous studies, but although many adult attributes diversify during childhood or even prenatally, and although lifetime fitness ... -
Feeding competition in wild female Assamese macaques (Macaca assamensis)
(2014-09-30)Food is one of the most important resources animals compete over and assessing the way individuals compete over such limiting resources is fundamental to our understanding of the adaptations of living organisms. In mammals, ... -
Female social relationships among wild Assemese macaques (Macaca assamensis)
(2014-07-14)It has been repeatedly shown that strong, affiliative social relationships (hereafter “social relationships”) are extremely important for human health and well-being. Increasingly there is evidence that non-human species ... -
Cooperation and competition in wild male Barbary macaques (Macaca sylvanus) in Morocco
(2013-10-07)Mammalian males compete for a non-sharable resource (receptive females) and are typically the dispersing sex, thus cooperation between males may appear counterintuitive. However, if both partners gain mutual benefits from ... -
The socio-endocrinology of female reproductive strategies in wild Assamese macaques (Macaca assamensis)
(2011-08-29)Sexual conflict is a prominent feature of animals living in multimale-multifemale groups, and drives the evolution of sex-specific reproductive strategies. Owing to divergent reproductive ...
