Collective anti-predator escape manoeuvres through optimal attack and avoidance strategies

The paper investigates collective escape patterns in sardines under predator attack, showing fountain effects arise from optimal escape rules and predator strategies.

Visual social information use in collective foraging

This study presents an agent-based model to explore how individual decision-making based on personal and social information influences collective foraging outcomes in different environments.

Moderate confirmation bias enhances collective decision-making in reinforcement-learning agents

This study shows that moderate confirmation bias improves collective decision-making in reinforcement-learning agents, but excessive bias can lead to suboptimal performance and polarization.

Experienced Social Partners Hinder Learning Performance in Naive Clonal Fish

This study shows that experienced social partners can hinder learning performance in naive clonal fish, challenging the assumption that social learning always enhances learning efficiency.

Evolutionary impact of size-selective harvesting on shoaling behavior: Individual-level mechanisms and possible consequences for natural and fishing mortality

This study shows size-selective harvesting alters shoaling behavior in zebrafish, affecting both fishing and natural mortality through changes in vigilance and social cue use.

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.

The wisdom of stalemates: consensus and clustering as filtering mechanisms for improving collective accuracy

The paper shows that stalemates in group decision-making can improve collective accuracy by filtering out incorrect decisions in both simple and complex environments.

A model of collective behavior based purely on vision

This paper presents a vision-based model of collective behavior that generates organized group dynamics without spatial representation or collision avoidance.

Social networks in the presence and absence of visual cues

This study compares social dynamics between cave and surface Atlantic mollies under different densities, finding surface mollies maintain social interactions better at low density.

Searching for structure in collective systems

The paper introduces a method to identify mesoscopic structures in collective systems by analyzing constituent interactions without assuming pairwise or Gaussian dynamics.

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.
