Intestinal parasites infecting captive non-human primates in Italy

open access: yesFrontiers in Veterinary Science
Non-human primates (NHPs) living in captive conditions are susceptible to intestinal parasites that can contribute to mortality and morbidity, and cause zoonotic infections.

Amacrine cell inputs to OFF midget ganglion cells in macaque retina

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The goal of this study was to explain the findings from physiological studies that OFF midget ganglion cells had larger receptive field centers than expected from their dendritic field diameters. First, we confirmed that OFF mRGCs (OFF MGC) receive input from diffuse bipolar cells (DB) as well as OFF midget bipolar cells (FMB ...

The flexible, the stereotyped and the in‐between: putting together the combinatory tool use origins hypothesis

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1235-1254, June 2026.
ABSTRACT Tool use research has long made the distinction between tool using that is considered learned and flexible, and that which appears to be instinctive and stereotyped. However, animals with an inherited tool use specialisation can exhibit flexibility, while tool use that is spontaneously innovated can be limited in its expression and facilitated

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1406-1462, June 2026.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Reading hominin life history in fossil bones and teeth: methods to test hypotheses regarding its evolution

open access: yesBiological Reviews, Volume 101, Issue 3, Page 1463-1478, June 2026.
ABSTRACT Human life history is derived compared to that of our closest living relatives, the great apes. It has been suggested that these derived traits are causally related to aspects of our ecology, social behaviour and cognitive abilities. However, resolving this requires that we know the evolutionary trajectory of our distinctive pattern of growth,

Social Drivers of Vocal Flexibility in Female Baboons

open access: yesEthology, 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.

Multimodal Optical Imaging and Modulation with Simultaneous Electrophysiology Through Smart Dura in Non‐Human Primates

open access: yesAdvanced Science, Volume 13, Issue 25, 4 May 2026.
This study demonstrates multimodal integration in non‐human primates, combining large‐scale, high‐density electrophysiology using Smart Dura with optical techniques such as multiphoton imaging (MPI), photothrombotic lesioning, optical coherence tomography angiography (OCTA), wide‐field intrinsic signal optical imaging (ISOI), and optogenetics.

Beyond Body Mass, Beyond Adulthood: The Ontogeny of Sexual Size Monomorphism

open access: yesAmerican Journal of Biological Anthropology, Volume 190, Issue 1, May 2026.
ABSTRACT Objectives Contest competition for mates and female reproductive energetics influence body size and sexual dimorphism across many primates; nevertheless, some monomorphic species defy these patterns. These deviations may reflect biological anthropology's focus on body mass and adult size as defining features of sexual dimorphism.

Monkey Meltdowns: Do Tantrums Influence Maternal Investment in Bearded Capuchin Monkeys?

open access: yesDevelopmental 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.

Comparison of Enamel, Dentin, and the Dentin–Enamel Junction in Horse, Dog, Wild Boar, and Macaque Using Confocal Raman Microscopy

open access: yesJournal of Raman Spectroscopy, Volume 57, Issue 5, Page 871-878, May 2026.
Confocal Raman microscopy was used to map the dentin–enamel junction (DEJ) across four mammalian species. Chemical maps highlighted variations in mineral (phosphate/carbonate) and organic (amide/CH) phase. These results provide a comparative Raman framework to link tooth microchemistry with species‐specific structure and function.
