Gestural Sequences in Wild Spider Monkeys (Ateles geoffroyi)
American Journal of Primatology, Volume 88, Issue 4, April 2026.Geoffroy's spider monkeys produce gestural sequences in the wild, mostly during aggressive, playful and sexual interactions. ABSTRACT To date, research on gestural communication in species other than great apes has been quite limited, especially in their natural habitat, although including a broader range of species in different settings is essential ...

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.
