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.

Differential acquisition of cocaine and heroin self-administration in a rat model of internalizing versus externalizing temperament

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.

From lab to ocean: bridging swimming energetics and wild movements to understand red drum (Sciaenops ocellatus) behavior in a tidal estuary

By integrating laboratory flow-respirometry, mesocosm accelerometer data, and multi-year field telemetry, this study reveals that while red drum can exploit turbulent wakes to reduce swimming costs in controlled settings, their wild habitat selection is primarily driven by ecological factors like foraging and predation refuge rather than hydrodynamic efficiency alone.

Vocal Signatures of Stress Relief: Effects of Appeasing Harness and Synthetic Pheromone on Puppy Whine Acoustics in Separation Context (Canis familiaris)

This study demonstrates that while calming interventions like synthetic pheromones and pressure harnesses do not reduce the frequency or intensity of puppy whining during separation, they effectively lower fundamental frequency, variability, and acoustic roughness, thereby revealing subtle reductions in emotional arousal through bioacoustic analysis.

Persistent male survival advantage in a protogynous hermaphrodite fish

Contrary to the typical expectation of higher male mortality in polygynous species, a study on the protogynous cleaner wrasse *Labroides dimidiatus* during the 2024 El Niño event revealed that terminal-phase males exhibited greater survival than initial-phase females, whose mortality more than doubled due to physiological vulnerabilities linked to faster growth rates.

Context-dependent mechanical reconfiguration is necessary for multifunctional behavior in a constrained hydrostat

This paper demonstrates that the sea hare's buccal mass achieves large odontophore protractions during distinct feeding behaviors through context-dependent mechanical reconfigurations, revealing a fundamental distinction between "constrained" and "unconstrained" muscular hydrostats that rely on different control strategies based on the presence of mechanical constraints.
