DOI: 10.1002/ajp.23392
Abstract: In primates, social relationships with a high frequency of social grooming are referred to as “affiliate relationships,” “friendship,” “bonding,” and are described as involving positive emotion. However, the psychological state during social grooming has not… read more here.

When males have females on their backs: Male's tolerance, solicitation, and use of female–male mounting in Japanese macaques
Sign Up to like & getrecommendations! Published in 2022 at "American Journal of Primatology"
DOI: 10.1002/ajp.23395
Abstract: Previous research on Japanese macaques has shown that female‐to‐male mounting (FMM) is performed by some females as an exaggerated form of sexual solicitation that may occur in the context of high female competition for male… read more here.

DOI: 10.1002/ajp.23411
Abstract: Olfactory communication plays an important role in the regulation of socio‐sexual interactions in mammals. There is growing evidence that both human and nonhuman primates rely on odors to inform their mating decisions. Nevertheless, studies of… read more here.

DOI: 10.1002/ajp.23463
Abstract: The self‐initiated split of a social group, known as fission, is a challenge faced by many group‐living animals. The study of group fission and the social restructuring process in real time provides insights into the… read more here.

DOI: 10.1002/ajp.23491
Abstract: Grooming is one of the most common cooperative behaviors among several animal species. However, the tactics used to cope with uncooperative partners in grooming interactions remain unclear. Japanese macaques (Macaca fuscata) solicit grooming from partners… read more here.

DOI: 10.1002/ajp.23500
Abstract: Glucocorticoids (GCs) are hormones released in response to stressors and can provide insight into an organism's physiological well-being. Experiencing chronic challenges to homeostasis is associated with significant deviations from baseline fecal GCs (fGCs) in many… read more here.
