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.

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 defensive responses to predators in mice are not obligatory or uniform but are instead flexibly shaped by environmental context, task demands, and individual variability, challenging the assumption that innate fear behaviors are automatically triggered by threat.
This paper applies differential geometry, algebraic topology, and adversarial robustness testing to sperm whale codas, revealing their complex hierarchical and topological structures, individual identity encoding, and social turn-taking dynamics while introducing the first adversarial benchmark for cetacean communication decoders.
This study on wild red foxes in Great Britain reveals that while the propensity to engage with novel tasks emerges early in urbanization, enhanced exploratory diversity and problem-solving abilities develop only after long-term, multi-decadal exposure to urban environments.
This study identifies methyl 3-ethyl-2-hydroxy-4-methylpentanoate (MEHMP) as the first known brood pheromone in ants, demonstrating that larvae of the clonal raider ant *Ooceraea biroi* secrete this volatile compound to chemically suppress adult egg-laying and regulate reproductive cycles without physical contact.
This study provides the first evidence that zebrafish exhibit a spatial-numerical association by reliably mapping smaller numerosities to the left and larger ones to the right, establishing them as a tractable model for investigating the neurobiological foundations of number-space mapping in basal vertebrates.
This paper introduces a hybrid recurrent neural network trained on synthetic data from feature-based reinforcement learning and serial hypothesis testing models to successfully decode latent human attention with over 80% accuracy, revealing a mechanism where value-derived hypotheses are continuously tested against incoming evidence.
This study reveals that naked mole rat colonies can undergo a peaceful, non-aggressive queen succession where subordinate females sequentially assume breeding roles in response to environmental stressors that impair the queen's fertility, challenging the traditional view that reproductive ascension in this species requires violent competition.
This study demonstrates that female *Aedes aegypti* mosquitoes rely on surface texture as a primary cue to guide egg-laying site selection, integrating it with water salinity and modulating their search speed to optimize offspring fitness.
This paper introduces a high-throughput framework that integrates 3D pose estimation with unsupervised hidden Markov modeling to transform rodent open-field behavior into discrete syllables, utilizing Shannon entropy and spectral eigenvalue metrics to quantify the organization and temporal persistence of spontaneous behavior as a stochastic dynamical system.
Through simulation experiments, this paper demonstrates that cognitive capacity determines both the likelihood and the specific strategy of social learning, revealing an inverse-U relationship where moderate capacity maximizes social information use and a shift from success bias to conformism as capacity increases.
