This study demonstrates that hummingbird hawkmoths exhibit stable, idiosyncratic lateralized visuo-motor control during proboscis probing, maintaining a persistent eye-proboscis-target axis through body posture adjustments that reveal both convergent principles with vertebrates and distinct sensory-motor plasticity in invertebrates.
This study demonstrates that European green toad larvae possess a trained magnetic compass orientation and illustrates how applying advanced mixed-effects circular statistics to repeated-measures designs can disentangle complex, multi-cue animal orientation strategies beyond simple overall effects.
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 paper proposes the use of affordable, weather-resistant home security cameras as a cost-effective alternative to commercial systems for monitoring small ectotherms, thereby enabling reliable behavioral observations and maximizing research budgets, particularly for scientists in South America.
This study demonstrates that in food-limited Black-legged kittiwake chicks, lower feeding rates predict higher stress-induced corticosterone levels, which in turn causally drive rapid, sex-specific increases in aggression and sibling elimination, particularly under conditions of nutritional scarcity.
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 study establishes the first comprehensive baseline of feeding ecology for the previously unstudied Mwera South chimpanzee community in Uganda's Bugoma Forest, revealing that while they adhere to regional ecological patterns, their unique behavioral traits suggest they occupy a historic cultural junction that offers new insights into the interplay between ecological constraints and cultural transmission in Eastern chimpanzees.
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 while chronic neuropathic pain does not globally disrupt sucrose reward-seeking or its acquisition in mice, it selectively impairs behavioral flexibility during reversal learning and alters pain-reward interactions in a sex-dependent manner, accompanied by specific changes in medial prefrontal cortex activity.
This study reveals that in the bean bug *Riptortus pedestris*, the sex-determination cascade *Rpfmd-Rpdsx* regulates the biosynthesis of specific volatile pheromones in the metathoracic gland, enabling male-male recognition and preventing erroneous mating attempts to ensure reproductive accuracy.
This study demonstrates that exogenous melatonin effectively alleviates diet and photoperiod-induced neurobehavioral deficits, anxiety, and depression in mice by modulating hippocampal inflammatory markers and restoring the BDNF-TrkB signaling pathway.
This study demonstrates that Usher syndrome type 2A-associated sleep disturbances in zebrafish arise from a novel role of usherin in the pineal gland's sleep-wake regulation, which operates independently of intact circadian clock gene expression and melatonin release.
This study demonstrates that while bumblebees can flexibly adjust carbohydrate and protein intake to maintain stable lipid collection and survive under cold stress, extreme heat disrupts their nutritional balancing, leading to reduced survival and highlighting the critical impact of thermal stress on pollinator health and ecosystem stability.
Using a transparent predictive coding model, this study reveals that while humans, baboons, and pigeons can all learn to recognize letter strings without semantic knowledge, their underlying orthographic processing strategies differ by phylogenetic distance, with humans and baboons relying more on letter-sequence representations and pigeons depending primarily on pixel- and letter-level features.
This study provides robust evidence that house crickets exhibit flexible, site-directed self-protection through targeted grooming of noxiously stimulated antennae, supporting the hypothesis that insects may experience pain-like states.
This study demonstrates that while low-dose d-amphetamine selectively improves visual attention in rats with poor baseline performance, atomoxetine impairs visual signal detection across attention phenotypes, highlighting potentially detrimental effects of this ADHD treatment compared to stimulant drugs.
This study demonstrates that microplastic exposure reduces boldness and exploratory activity while increasing feeding frequency in zebrafish across different size-selective harvesting lines, with most behavioral responses remaining robust to prior evolutionary history despite the lack of observed growth impacts.
