The myoglobin of primates: the Night Monkey, Aotes trivirgatus (Cebidae, Platyrrhini, Anthropoidea) [PDF]
, 1984 The amino acid sequence of the myoglobin of the South American Night Monkey, Aotes trivirgatus, is identical to that of the marmoset (Callithrix jacchus [1]) except for residue 21 which is isoleucine in the marmoset, like in all other anthropoids, but ...

Evolutionary Signal and Development of the Foramen Dorsum Sellae (Nov.) Across Primates
Journal of Morphology, Volume 287, Issue 9, September 2026.The dorsum sellae of the sphenoid bone occasionally exhibits an accessory opening, though its significance is unknown. We scored its presence in humans (N = 114) and 30 non‐human primate genera (N = 1468) and combined histological, dissection‐based, and phylogenetic approaches to understand its function. The foramen occurred in 12% of humans and 33% of

Life‐History Correlates of Enamel Microstructure in Cebidae (Platyrrhini, Primates) [PDF]
The Anatomical Record, 2011 AbstractPrevious studies have examined tooth eruption as it relates intrinsically to body mass, brain mass, and other life history variables, and extrinsically to ecological factors (e.g., age at foraging independence, environmental risk aversion, and maternal investment).

American Journal of Primatology, Volume 88, Issue 6, June 2026.Food sharing between mother and offspring in capuchin monkeys is a response to the infant's begging. Infants solicit more frequently high‐quality and hard‐to‐process foods and they are more likely to succeed when they are older and if the food item is not a lizard. ABSTRACT In primates, food sharing from mothers to infants may serve two main functions:

Guidelines and considerations for capturing and collaring wild primates: a case study with capuchin monkeys (Sapajus nigritus cucullatus) [PDF]
Anais da Academia Brasileira de CiênciasMany aspects of the ecology, evolution and social behavior of wild-living primates remain un-explored and require further investigation. While long-term field studies are crucial for addressing conservation concerns for many primates’ species, acquiring ...

Monkey Meltdowns: Do Tantrums Influence Maternal Investment in Bearded Capuchin Monkeys?
Developmental Psychobiology, Volume 68, Issue 3, May 2026.ABSTRACT Tantrums are widely discussed in human development literature and are typically defined as displays of frustration or anger. In behavioral ecology, they are hypothesized to function as a strategy for securing greater maternal investment. Infant primates often exhibit tantrums when their attempts to obtain maternal care are rejected.
