Partner Choice and Context‐Dependent Sex Differences in Rat Rough‐and‐Tumble Play

European Journal of Neuroscience, Volume 63, Issue 3, February 2026.
When given partner choice in triadic play, male rats showed a robust preference for female partners, whereas females formed partner preferences that were not sex specific. Females initiated less play in mixed‐sex groups but played at male‐typical levels in all‐female groups, demonstrating that sex differences in rough‐and‐tumble play arise both from ...

Ultrastructural aspects of lingual papillae in squirrel monkey (Saimiri sciureus)

, 2011
Saimiri sciureus is one of the smallest Cebidae native of Amazon region and also found at the biological reserve of northeast Atlantic forest. It is an omnivore animal, with diversified diet that directly influences the lingual mucosa, which includes ...

Immunoprecipitation as a tool for studying humoral immunity of natural and experimental hosts of Herpesvirus saimiri [PDF]

, 1983
Herpesvirus saimiri strain 11 and attenuated H. saimiri strain 11 proteins synthesized during the lytic cycle of virus replication were used for immunoprecipitation with various sera from natural (Saimiri sciureus) and experimental (Saguinus nigricollis,

Cicada as a food for mammals: a global review and implications for mammal behaviour and populations

Wildlife Biology, Volume 2026, Issue 1, January 2026.
Cicadas (Hemiptera: Cicadidae) are among the most important insect prey for many vertebrate predators, including birds and mammals, owing to their large size and high nutritional value. Although the ecological roles of cicadas as prey for birds have been well documented, the interactions between mammals and cicadas are relatively unknown.

Living Together: Behavior and welfare in single and mixed species groups of capuchin (Cebus apella) and squirrel monkeys (Saimiri sciureus)

, 2010
There are potential advantages of housing primates in mixed species exhibits for both the visiting public and the primates themselves. If the primates naturally associate in the wild, it may be more educational and enjoyable for the public to view ...

Tolman's Sunburst Maze 80 Years on: A Meta‐Analysis Reveals Poor Replicability and Little Evidence for Shortcutting

European Journal of Neuroscience, Volume 63, Issue 1, January 2026.
In 1946, Tolman et al. reported that rats could take a novel shortcut to a goal after training on an indirect route, supporting the Cognitive Map theory. However, a review of subsequent Sunburst maze studies shows this is an outlier: shortcutting has been observed in only a relatively small fraction of experiments.

Video‐Sound Recording Devices Reveal Multiple Drivers of Nocturnal Vocalizations in Tibetan Macaques

Ecology and Evolution, Volume 15, Issue 12, December 2025.
This study investigates the nocturnal vocal behavior of Tibetan macaques in Huangshan, China, using 4G infrared cameras and passive acoustic monitoring (PAM). Findings reveal a bimodal vocalization pattern (18:00–19:00 and 21:00–23:00), influenced by sex, age, social centrality, kinship, and ecological factors such as wind direction, temperature, and ...

Squirrel Monkeys (Saimiri sciureus) Infected with the Agent of Bovine Spongiform Encephalopathy Develop Tau Pathology

, 2012
Squirrel monkeys (Saimiri sciureus) were infected experimentally with the agent of classical bovine spongiform encephalopathy (BSE). Two to four years later, six of the monkeys developed alterations in interactive behaviour and cognition and other ...

Fibrosarcoma on the leg of an adult rhesus macaque (Macaca mulatta)

Veterinary Record Case Reports, Volume 13, Issue 4, December 2025.
Abstract This case describes a fibrosarcoma on the left upper leg of an adult female rhesus macaque. The patient was initially presented with a defined swelling at the caudolateral side of the upper leg. Medially from the growth, a swollen circular wound had formed with a fistula leading in the direction of the mass.

Close encounters of the friendly kind: pacific between‐group interactions in primates

Biological Reviews, Volume 100, Issue 6, Page 2257-2284, December 2025.
ABSTRACT While intergroup conflict features prominently in the behavioural ecology literature, its antonym, intergroup peace, has been a rather neglected phenomenon until recently. Neighbourly relations and affiliative interactions are far from uncommon.
