Are there morpho‐acoustic patterns of adaptation in nonhuman primate ears? Testing the role of ecology and habitat in shaping ear morphology and function

The Anatomical Record, EarlyView.
Abstract Analysis of the variation in the bony structures of the inner and middle ear provides critical insights into functional morphology, as well as adaptive morphology across primates. In this study, we investigated whether ear morphology patterns are related to the ecological characteristics of species and their habitats to test two acoustic ...

Foraging and movement flexibility shape seed dispersal by an arboreal primate in a modified landscape

Oikos, EarlyView.
As habitats change, the effectiveness of animal‐mediated seed dispersal increasingly depends on animal responses to altered structure and resources. With habitat loss and degradation accelerating across the tropics, understanding how dispersers' foraging behavior and movement influence seed removal and deposition is critical to promoting forest ...

From steps to home ranges: How habitat disturbance influences the movement drivers of an arboreal primate

Journal of Animal Ecology, EarlyView.
Challenging the narrative about howler monkeys' high resilience to anthropogenic changes, our multiscale analysis reveals the costs of habitat disturbance to their movement ecology. We identify thermal limitations, reduced travel efficiency, and significant spatial saturation.

The effect of food provisioning on the nutrient intake of wild and captive primates : implications for the conservation management of wild and captive populations : a thesis presented in partial fulfilment of the requirements for the degree of Doctorate of Philosophy in Ecology, Massey University, Albany, New Zealand [PDF]

, 2017
Many non-human primate populations worldwide are threatened with extinction. Various measures are taken to save these species. Amongst these efforts are habitat protection, restoration, and public education, including wildlife tourism.

Relationship quality affects fission decisions in wild spider monkeys (Ateles geoffroyi) [PDF]

Fission-fusion dynamics are thought to be mainly a response to differential availability of food resources. However, social factors may also play a role.

Validation of Immunoassays for Total Thyroxine and Free Thyroxine and Age and Sex‐Related Variation in Thyroid Hormone Serum Concentrations in Orangutans (Pongo sp.)

Journal of Medical Primatology, Volume 55, Issue 3, June 2026.
ABSTRACT Background Thyroid disease is reported in orangutans, but to properly diagnose and manage these disorders, reference intervals for circulating thyroid hormones are needed. Methods Commercial immunoassay kits for total thyroxine (TT4) and free thyroxine (FT4) were validated for use in orangutans (Pongo spp.).

Optimal random search, fractional dynamics and fractional calculus

, 2013
What is the most efficient search strategy for the random located target sites subject to the physical and biological constraints? Previous results suggested the L\'evy flight is the best option to characterize this optimal problem, however, which ...

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.

Ecomorphological determinations in the absence of living analogs:The predatory behavior of the marsupial lion (Thylacoleo carnifex) as revealed by elbow joint morphology [PDF]

, 2016
Thylacoleo carnifex, or the “pouched lion” (Mammalia: Marsupialia: Diprotodontia: Thylacoleonidae), was a carnivorous marsupial that inhabited Australia during the Pleistocene.
