Animal behavior and cognition explores the fascinating inner lives of creatures big and small, from how a crow solves a puzzle to why dogs seem to understand human emotions. This field investigates the mental processes and social interactions that drive the natural world, revealing that intelligence and awareness take many forms across species.
At Gist.Science, we bring these discoveries directly from bioRxiv to your screen. Our team processes every new preprint in this category from bioRxiv, ensuring you have access to the latest research through both detailed technical summaries and easy-to-understand plain-language explanations. Whether you are a researcher or a curious reader, you can dive deep into the data or grasp the core concepts without the barrier of dense academic jargon.
Below are the most recent papers exploring the minds and behaviors of animals, freshly processed and ready for you to explore.
This study demonstrates that in naturalistic foraging tasks, both the temporal distribution of reward availability and the reliability of sensory cues significantly shape how macaque monkeys allocate their time and effort across different patches.
This study characterizes the morphometric variations among SiifDacar, Hoor, and Eyddimo dromedary camel types in Mogadishu, Somalia, revealing significant differences in body dimensions by breed and sex, with SiifDacar females being the largest and males generally exceeding females in size, thereby supporting the classification of these local types as distinct breeds.
This study reveals that adolescent social isolation in female mice induces latent deficits in maternal care and intergenerational social dysfunction via hypofunction of the mCg-to-PrL neural circuit, which can be rescued by co-housing with experienced mothers.
By reconstructing *C. elegans* foraging in 3D, this study reveals that the worm achieves optimal search efficiency through a hierarchical locomotion strategy driven by cost constraints and a limited shape-space, supporting a unifying framework where optimal decision-making emerges from maximizing information gain under embodied constraints.
Despite lacking a fovea and high spatial acuity, tree shrews demonstrate robust transformation-tolerant object recognition comparable to primates, suggesting that high-level visual generalization relies on intermediate and deep cortical processing rather than front-end optical resolution.
Using selectively bred rats to model internalizing and externalizing temperaments, this study demonstrates that the acquisition of cocaine and heroin self-administration is differentially influenced by drug class, sex, and temperament, revealing that the female-specific "telescoping effect" for opioid addiction is primarily driven by externalizing traits.
This study demonstrates that male mice selectively approach conspecifics based on specific acoustic and temporal features of ultrasonic vocalizations recorded during social chasing, particularly responding to the calls of chased individuals rather than those of the chasers.
This study demonstrates that while bumblebees' response latencies in judgment bias tasks reflect stable individual traits, their actual chamber choices are largely state-dependent and influenced by transient external factors.
This study of the cleaner wrasse *Labroides dimidiatus* reveals that incomplete social dominance and flexible life-history strategies, such as rapid growth and harem switching, drive complex sex change dynamics that challenge traditional models of socially regulated protogynous sex change.
Using an agent-based model of Andean condors, this study demonstrates that in unpredictable, patchy landscapes, individuals who combine intermediate risk-taking with high reliance on social information can achieve up to 41% energy savings compared to asocial movement.
