This study finds that Japanese macaques adjust their flight initiation distance based on a dominant's aggressiveness, not rank differences.

Nest attributes influence choice accuracy, but not decision speed in acorn ants

This study examines how nest attributes affect decision accuracy and speed in acorn ants, finding no effect on speed but increased accuracy with more attributes.

This paper introduces a Python-based model to study how family-based selection affects phenotypic variability in D. melanogaster, showing that it can increase variability more effectively than individual-based selection.

Phenological turnover matters when making trait-based predictions of plant-pollinator interactions

The paper investigates how phenological turnover affects trait-based predictions of plant-pollinator interactions by analyzing individual-level trait data from an Arctic community.

Pros and cons of group averaging in studies of stochastic rodent locomotion

The paper examines group averaging in rodent locomotion, finding that ensemble-averaged distributions differ from individual ones due to population heterogeneity and proposing a reference rodent model for personalized comparison.

High environmental temperatures put nest excavation by ants on fast forward: they dig the same nests, faster.

This study shows that higher temperatures increase the digging rate of ants but do not alter the shape of their nests.

vassi - verifiable, automated scoring of social interactions in animal groups

The paper introduces vassi, a Python package for automated scoring of social interactions in animal groups, demonstrating its effectiveness on both benchmark and naturalistic datasets.

XAI-based Data Visualization in Multimodal Medical Data

This paper examines advanced XAI techniques for multimodal medical data, focusing on perturbation-based, concept-based, and example-based explanations to improve model interpretability in healthcare.

Motor history influences behavioral strategy more than response outcome in Drosophila melanogaster

The paper investigates how motor history affects decision-making in Drosophila, finding that past motor activity influences strategy more than response outcome.

Object permanence in domestic cats (Felis catus) using violation-of-expectancy by owner and stranger

This study tests object permanence in domestic cats using visible and invisible displacement tasks, finding that cats show different behaviors based on person familiarity and trial type.

Evidence of play behavior in captive California Two-Spot Octopuses, Octopus bimaculoides.

The paper describes play behavior in captive California Two-Spot Octopuses to better understand their behavioral repertoire and welfare.

Flexible foraging effort shapes Adelie penguin reproductive success across Antarctica and sea ice conditions

This study shows that Adelie penguin foraging effort and trip duration affect reproductive success under varying sea ice conditions, with clear thresholds indicating environmental stress.

Fish locomotor variation: connecting energetics and kinematic modulation

The paper examines how fish locomotor kinematics and energetics vary with environmental and biological factors, showing correlations between kinematic modulation and metabolic rate changes.

Exploring the association between stress-related hormonal changes, behaviours and facial movements after a trotting exercise in French Standardbred

This study examines how stress hormones, behaviors, and facial movements change in horses after trotting exercise, finding links between hormone levels and specific behaviors indicating stress.

Early Life Outcomes of Prenatal Exposure to Alcohol and Synthetic Cannabinoids in Mice

This study examines the effects of prenatal alcohol and synthetic cannabinoid co-exposure on mouse offspring survival, physical development, and neurobehavioral outcomes, finding increased mortality and sex-specific behavioral impairments.

To Peck or Not To Peck: The influence of early-life social environment on response inhibition and impulsive aggression in Japanese quails

Japanese quails reared in groups of 15 versus five pecked a transparent cylinder less, but rearing group size did not change impulsive aggression in either context.

A flexible fluid delivery system for rodent behavior experiments

The paper introduces an open-source, stepper-motor-based system for precise liquid delivery in rodent behavior experiments and validates its performance in psychophysics tasks and electrophysiology.

Timing and social dynamics of divorce in wild great tits: a phenomenological approach

This study examines social dynamics and timing of divorce in wild great tits, finding distinct social association patterns in divorcing pairs during the non-breeding season.

A phototaxis assay to measure sublethal effects of pesticides on bees

This paper introduces a phototaxis assay to detect sublethal pesticide effects on bees, showing it can identify field-realistic acetamiprid exposure levels in both solitary and honey bees.

Personality development in wild house mice: Evidence for a nutrition-dependent sensitive period early in life

This study investigates how food quality during different life stages affects stress coping and personality development in wild house mice, finding that early nutrition influences long-term behavioral strategies.

Same-sex mounting in single-housed C57BL/6J female mice is not coupled to estrous state

This study shows that same-sex mounting in single-housed C57BL/6J female mice is not influenced by the estrous state of either the mounter or the stimulus female.

Flexibility in the face of climate change? A rapid and dramatic shift toward later spring migration in Hudsonian Godwits (Limosa haemastica)

This study tracks shifts in Hudsonian godwit migration timing and finds a rapid 6-day delay with no sex differences, suggesting non-adaptive responses to climate change.

Novel Exploration Growth Quantifies Anxiety-like Behaviour in the Elevated Plus Maze

This paper introduces a new measure, novel exploration growth, to quantify anxiety-like behaviour in the elevated plus maze by capturing both exploration and avoidance in a single time series.

Navigating in clutter: How bumblebees optimize flight behaviour through experience

This study shows that experienced bumblebees optimize flight in cluttered environments through learning, not just reflexes, as transparent obstacles affect naive bees more than experienced ones.

Fine-scale movement data reveal surface foraging and nocturnal flight activity in the endangered Bermuda petrel

This study uses fine-scale movement data from Bermuda petrels to reveal surface foraging and nocturnal flight behaviors, providing insights into their foraging strategies and activity patterns.

16p11.2 duplication shows early male-biased impacts on reward learning, but NMDA receptor antagonism reduces optimal choice selection in both wildtypes and 16p11.2 duplication

This study examines how 16p11.2 duplication affects reward learning in mice, finding male-biased impacts in early training but no genotype effect in a bandit task, while NMDAR antagonism impairs choice flexibility in all animals.

Modality specific memory enhancement in Heliconius butterflies

Heliconius butterflies retain odour associations over eight days no better than outgroup Heliconiini, contrasting with their superior visual long-term memory, consistent with a modality-specific memory enhancement.
