July 2004 in “Journal of Medical Primatology” In this study, zinc toxicosis in infant baboons was attributed to excessive environmental exposure, highlighting the importance of cage design in captivity and potential use of baboons as a developmental model.
This study observed that the development of the pars intermedia in long-tailed macaques is closely associated with changes in skin pigmentation during pre- and postnatal periods through melanocyte-stimulating hormone and ACTH activity.

August 2024 in “Journal of Morphology” This study observed that developing mammary organs in Monodelphis domestica show mammary hairs in 12-week-old females, which disappear by 18 weeks, with findings suggesting shared characteristics between their nipples and eutherian nipples, supporting the evolutionary link between mammary glands and hair organs.
This study found that social hair plucking in captive rhesus macaques may share traits with both prosocial and aggressive behaviors and is associated with alopecia and hair cortisol levels.
February 2023 in “Journal of medical primatology” In this study, pair housing of rhesus macaques after intrafacility transfer reduced some undesirable behaviors and diarrhea compared to single housing, although no cortisol level differences were observed.

February 1997 in “Teratology” This study demonstrated that high oral doses of finasteride caused external genital abnormalities in male rhesus monkey fetuses, but intravenous doses did not lead to abnormalities.
In this study of captive rhesus macaques, social hair plucking was related to kinship, showed characteristics of both prosocial and aggressive behaviors, and was associated with alopecia and hair cortisol concentrations in females.

March 2004 in “Mammalian genome” KAP genes are crucial for hair development and show both shared and unique traits in humans, chimpanzees, and baboons.
June 2026 in “Journal of Applied Animal Welfare Science” This study found that social hair plucking in captive rhesus macaques is linked to alopecia and possibly relates to stress in females.
This study observed that in captive rhesus macaques, social hair plucking is linked to alopecia and has kinship patterns similar to grooming, suggesting it may be socially influenced, though the health impacts and stress hormone (cortisol) changes involved remain uncertain.
