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 ...

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.

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 ...

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.
