Familiarity modulates preference for joint feeding with conspecifics in rats

This study shows that rats prefer joint feeding with unfamiliar non-cagemates over solitary feeding, indicating a high degree of social tolerance and prosocial behavior.

Measuring context dependency in birdsong using artificial neural networks

This study uses artificial neural networks to measure context dependency in birdsong, finding that context dependency decreases with finer syllable classifications.

Effects of short-term isolation on social animals' behavior: an experimental case study of Japanese macaque

This study examines how short-term isolation affects the movement patterns of Japanese macaques using Bluetooth tracking and machine learning to identify isolation vs. group behavior with high accuracy.

Large male proboscis monkeys have larger noses but smaller canines

The paper examines the relationship between nose and canine sizes in male proboscis monkeys, finding a negative correlation between body and canine sizes due to ecological trade-offs.

Deep Texture Representations as a Universal Encoder for Pan-cancer Histology

This paper introduces deep texture representations (DTRs) as a universal encoder for cancer histology, enabling accurate prediction of genomic features and cancer types from histological images.

Agent-based simulation for reconstructing social structure by observing collective movements with special reference to single-file movement

The paper uses agent-based simulations to reconstruct animal social structures from single-file movement data using the Louvain algorithm.

Non-Parametric Analysis of Inter-Individual Relations Using an Attention-Based Neural Network

This paper introduces a non-parametric neural network with attention mechanism to analyze inter-individual relations from location data, successfully recovering simulated relations and discovering female-oriented social patterns in Japanese macaques.

Mate sharing in male stump-tailed macaques as a possible case of coalition-like behavior to modify the group-wise fitness distribution

The paper observes facultative mating sharing among male stump-tailed macaques and models the conditions under which such coalition-like behavior could be evolutionarily advantageous.

Animals exhibit personality traits in their movement: a case study on location trajectories of primates

This study identifies personality traits in movement patterns of Japanese macaques using 3D location data and neural network analysis.
