The paper investigates whether social associations between breeders and helpers in sociable weavers are linked to the help received, finding stronger foraging bonds and positive correlations between social affiliations and help provided.

This study genetically modifies zebrafish to demonstrate how altering individual traits can tune collective behavior, showing mutant fish exhibit more orderly motion than wildtype.

This study compares navigation behaviors in 15 ant species, finding that olfactory navigation is dominant, path integration is limited to arboreal ants, and view-based navigation is influenced by body size and eye size.

This study shows curcumin reduces arsenic trioxide-induced behavioral, oxidative, and morphological damage in mice striatal regions.

This study investigates how Australian desert ants learn and navigate during colony relocation, finding that relearning walks at both old and new nests are critical for successful relocation and foraging.

The paper examines how BaYaka mothers balance childcare and foraging tasks in Congo Basin, finding that infant presence does not limit travel distance or food returns but increases group foraging efficiency.

This study examines bird species composition in rice plantations at different harvesting stages and evaluates the impact of surrounding vegetation on avian abundance in Weppa Farm, Nigeria.

This study shows that experienced Melophorus bagoti ants dump waste more efficiently and with spatial fidelity compared to naive ants, suggesting learning improves waste disposal and navigation.

This study shows that weakly electric fish adjust their movement and sensory processing based on illumination levels, switching between active sensing and multisensory reweighting near a critical threshold.

This study evaluates a prison-based dog training program, finding improved dog behavior and no negative welfare impacts.

The paper uses computational methods to analyze mouse behavior and identifies a bait-and-switch escape strategy that reduces social conflict.

The paper tests Eurasian jays' ability to reason by exclusion using modified 2-cups tasks and finds they succeed, supporting a link between caching behavior and exclusion reasoning.

This study shows that a single dose of psilocybin or psychedelic mushroom extract reduces excessive self-grooming in SAPAP3 KO mice, with effects lasting up to 7 weeks.

This study examines how continuous and intermittent lead exposure affects synucleinopathies, finding increased aSyn inclusions and neurobehavioral impairments in animal models.

The paper tests if physically stressed bumblebees show pessimistic behavior in an active choice judgment bias test, finding they expect less reward.

This paper introduces MAIRL, a multi-agent inverse reinforcement learning framework that decomposes joint value functions into individual value maps and interaction terms, revealing interpretable social value representations in mice and primates.

The paper investigates sex-specific perching behavior in black soldier flies, finding females perch more frequently than males, especially in the morning and early adulthood.

This study shows that the circadian clock in Antarctic krill drives bimodal swimming activity patterns, which may underlie seasonal behaviors like diel vertical migration.

This paper introduces a novel behavioral apparatus, the Vertical Maze, to study spatial and social cognition in rats and finds that rats can discriminate spatial distance and social novelty using multisensory cues.

The paper shows that solitary living in bush Karoo rats is not driven by aggression but by social tolerance and dispersal.

The paper examines age-related differences in activity patterns of Brown Pelicans, testing competitive exclusion and experience-based adaptation hypotheses, and assesses human fishing impacts on their behavior.

This study uses a judgment bias task to show that stress induces pessimistic behavior in cuttlefish, indicating a negative affective state.

The paper describes field observations of male-male agonistic behavior in the wood-feeding cockroach Panesthia angustipennis, revealing strategies for female protection and insights into evolutionary social behavior.

This paper introduces a framework to infer agents' internal models from behavior, revealing that suboptimal decisions arise from interactions between learning rules and environment representations in rats.

The paper tests how repellent and masking odorants affect the optokinetic response in Drosophila melanogaster during flight.

This study shows that inhibiting the striatal indirect pathway during the second postnatal week in mice causes long-lasting deficits in motivated behavior and dopamine adaptation.

This study shows Drosophila larvae can form short-term associative memories by linking temperatures with appetitive or aversive stimuli through thermal conditioning.

This study examines the impact of visitors on chimpanzee behavior at a rescue center, finding no significant increase in abnormal or aggressive behaviors and a slight decrease in affiliative behaviors, suggesting visitor interactions may not harm welfare.

This study compares sleep and activity patterns of Aedes albopictus mosquito strains from different geographic origins, finding heritable differences in activity levels but not peak activity times.

This study compares activity and sleep levels across 17 Ae. aegypti lines, finding population differences linked to host preference, ancestry, and human population density.
