Honey bee drones are synchronously hyperactive inside the nest

This study tracks honey bee drones inside the nest and finds they exhibit synchronized hyperactivity in the afternoon, influenced by weather and social cues.

Learning to embed lifetime social behavior from interaction dynamics

The paper introduces a temporal matrix factorization model to learn temporally consistent functional roles from social interaction networks in honey bees, enabling comparison of individual roles across time and colonies.

The dominant axes of lifetime behavioral variation in honey bees

This study quantifies behavioral variation in honey bees over their lifetimes and under environmental changes, identifying two dominant behavioral axes and showing individual consistency and colony-level adaptability.

Social networks predict the life and death of honey bees

The paper develops a method to predict honey bee task allocation, survival, and behavior using social network descriptors without interfering with colonies.

Group-level patterns emerge from individual speed as revealed by an extremely social robotic fish

This study shows individual speed differences in guppies shape collective behavior patterns through robotic fish experiments.

Consistent behavioural syndrome across seasons in an invasive freshwater fish

The paper investigates whether dispersing guppies exhibit different behavioral traits than those remaining in the source population, finding consistent behavioral syndromes across seasons and populations.

Guppies prefer to follow large (robot) leaders irrespective of own size

The study shows that guppies follow larger robotic fish leaders regardless of their own size or risk-taking behavior, indicating leadership preference is based on size rather than behavior.

Using a robotic fish to investigate individual differences in social responsiveness in the guppy

This study uses a robotic fish to examine individual differences in social responsiveness in guppies, finding that responsiveness is an independent trait separate from boldness and activity.
