This study investigates the flight kinematics of black soldier flies subjected to discrete headwind gusts, revealing rapid, asymmetric wing and body responses that combine passive and active control mechanisms to maintain stability, thereby offering critical insights for designing robust micro aerial vehicles.
This study demonstrates that Ring Finger Protein 10 (RNF10) signaling in the dorsal hippocampus is essential for cognitive flexibility by linking synaptic NMDAR activation to specific transcriptional programs that enable the brain to adapt behavior to changing environmental contexts.
This study provides the first evidence that stochastically induced behavioral differences in naturally clonal fish can be non-genetically transmitted across generations, as mothers with higher feeding activity produce more active offspring, suggesting such variation may significantly contribute to evolutionary processes and population adaptability.
By combining in vivo observations of starlings evading a robotic predator with a data-driven 3D agent-based model, this study reveals that collective escape patterns emerge from individual-level rules governed by the speed of information propagation, relative predator positions, and flock hysteresis.
This study demonstrates that mice will acquire and maintain operant lever-pressing behavior solely for contingent green light exposure, establishing light as a non-physiological reward that cannot be explained by thermal cues or alerting effects and offering a novel model for understanding light-driven behavioral addictions.
This paper presents a rotation-augmented artificial neural network that accurately predicts Drosophila body yaw orientation from translational flight trajectory data, enabling the recovery of critical behavioral information from existing datasets lacking dedicated orientation hardware.
This paper demonstrates that confidence in perceptual decisions does not rely on a single computational mechanism, but rather adapts to task demands, with an intentional architecture better explaining incentivized motion discrimination and a hierarchical probabilistic model better capturing un-incentivized luminance discrimination.
Despite comparable overall copulation rates across dominance ranks, male bonobos at Wamba exhibit reproductive skew through rank-biased access to females during their likely fertile period, a dynamic facilitated by subordinate males shifting mating efforts toward non-fertile females to reduce contest competition.
This study demonstrates that a novel smartphone-based pointing task in a real-world environment captures stable spatial memory performance that correlates with traditional laboratory measures when analyzed through a unified relational framework, supporting the use of mobile tools as scalable complements for assessing Alzheimer's disease risk.
Based on 32 years of data from Florida Scrub-Jays, this study reveals that while limited dispersal and site fidelity increase inbreeding risk, the species actively avoids mating with close relatives, yet inbreeding tolerance still results in reduced lifetime reproductive success for specific individuals despite the presence of multiple avoidance mechanisms.
This paper reports the first documented instance of spontaneous, tool-assisted drumming in a captive Galah, which produced rhythmically organized tapping with a hierarchical structure without training, thereby expanding the known scope of rhythmic and tool-using abilities in parrots.
EthoClaw is an open-source, AI-driven workflow platform that integrates local video processing, markerless tracking, and LLM-generated reporting to democratize reproducible neuroethology research through a unified, natural language interface.
This study demonstrates that free-flying honeybees exhibit a spontaneous numerical bias, preferring to rely on item count over non-numerical visual cues like area and space when discriminating quantities, while also revealing individual variation in strategy and evidence of an oriented mental number line.
This study demonstrates that human resource sharing in groups is driven by a strategic balance between maintaining stable partnerships and exploring alternatives, a dynamic process best explained by a reinforcement learning model incorporating Theory of Mind rather than simple reciprocity or fairness concerns.
This study characterizes a novel *Sts*-deficient mouse model that lacks steroid sulfatase activity and exhibits increased activity, higher normalized heart weights, and sex-specific behavioral differences, providing a valuable tool for investigating the physiological and behavioral consequences of STS deficiency.
This study reveals that the complex calls of little auks, a non-vocal learning seabird, exhibit intricate temporal structures shaped by linguistic laws, prosodic patterns, and sex-specific rhythmic rallentando, demonstrating that their communication is driven by both universal efficiency and the specific social pressures of colonial life.
This paper introduces CLiQR, an open-source, low-cost, and scalable capacitive lickometry system that enables high-throughput, full-trace recording of rodent drinking behavior in home-cage environments, offering a reliable proxy for fluid intake while supporting retrospective algorithmic improvements.
This study characterizes the vocal repertoire of adult domestic pigs in a laboratory setting by analyzing 1,136 vocalizations to define five major call classes and 16 distinct types, thereby establishing a detailed acoustic framework to support non-invasive welfare assessment and comparative research.
This study demonstrates that while visual and olfactory cues independently influence oviposition acceptance in the Mediterranean fruit fly under no-choice conditions, their integration in choice scenarios reveals a strong correlation between acceptance and preference, suggesting that highly attractive fruits in isolation become even more preferred when presented alongside alternatives, with significant implications for behavior-based pest management.
This study demonstrates that the mere presence of a home cage running wheel, rather than the act of running itself, induces a lasting reduction in social motivation and ultrasonic vocalizations during same-sex interactions in adult female C57BL/6J mice, highlighting a critical environmental factor for experimental design.
