Testing the Energetics of Gestation and Growth Hypothesis for Human Secondary Altriciality

Evolutionary Anthropology: Issues, News, and Reviews, Volume 35, Issue 2, June 2026.
ABSTRACT The pronounced neurological immaturity, yet increased birthweight of human neonates relative to other primates, known as secondary altriciality, is traditionally attributed to obstetric constraints arising from pelvic adaptations for bipedal locomotion and childbirth—the so‐called obstetrical dilemma.

Community perceptions and management of the fleshy‐fruited invasive alien plant Pyracantha angustifolia: Insights from South Africa's Montane grasslands

People and Nature, Volume 8, Issue 6, Page 1869-1879, June 2026.
Abstract Invasive alien plants can provide economic or cultural benefits to local communities, influencing perceptions and potentially affecting management decisions. Understanding these perceptions is crucial to avoiding inefficiencies, misunderstandings and conflicts in the management of invasive alien species.

Role of Local Medium to Large Mammalian Species in Seed Dispersal of Fleshy‐Fruited Invasive Alien Plants in the Montane Grassland Biome of South Africa

African Journal of Ecology, Volume 64, Issue 4, June 2026.
ABSTRACT Fleshy‐fruited invasive alien shrubs are an increasing problem in the grasslands of South Africa, where they alter vegetation and threaten biodiversity. They are predominantly bird‐dispersed in forest systems, but their spread in grassland ecosystems remains understudied, including their dispersal by mammals.

A review of participatory mapping in conservation science and practice

Conservation Science and Practice, Volume 8, Issue 6, June 2026.
There has been a recent increase and diversification in the use of participatory mapping in the field of conservation, however, methodological standards remain both disjointed and confounding. We conducted a comprehensive review of the conservation participatory mapping literature and synthesized geographical, temporal, and topical trends across a ...

Social complexity in a large and small group of olive baboons

, 2015
Group size is known to correlate with various indices of brain size in the primates. The possibility that increases in group size foster social complexity forms the central empirical topic of this thesis.

Social Drivers of Vocal Flexibility in Female Baboons

Ethology, Volume 132, Issue 6, Page 390-398, June 2026.
Female olive baboons selectively grunt when encountering females with dependent offspring. Grunting likelihood depends on rank differences and the strength of their social bond. This study adds to the evidence that nonhuman primates have evolved to use structurally‐inflexible vocalisations in population and context‐flexible ways.

Infectivity of Trypanosoma (Trypanozoon) brucei gambiense for baboons (Papio hamadryas, Papio papio) [PDF]

Annales de la Societe belge de medecine tropicale, 1991
In order to study sensitivity or resistance of T.b. gambiense to baboon serum, two species of baboons, P. hamadryas and P. papio were inoculated with T.b. gambiense clone LiTat 1.1. Both species were receptive to infection but, parasitological and immunological parameters showed that P. papio was more trypanotolerant than P. hamadryas. The VAT-specific

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.).

Change point analysis of travel routes reveals novel insights into foraging strategies and cognitive maps of wild baboons

, 2013
Efficient space use is a critical challenge for animals relying on stationary resources. It is often difficult with purely observational methods to gain unambiguous insight into any ability of primates to manage and process spatial information ...
