Evolution of Swarming Behavior Is Shaped by How Predators Attack

This work corroborates Hamilton's selfish herd hypothesis in a digital evolutionary model, refines the assumptions of the selfish herd hypotheses, and generalizes the domain of danger concept to density-dependent predation.

A Balanced Mixture of Antagonistic Pressures Promotes the Evolution of Parallel Movement

The results suggest that a mixture of antagonistic external pressures that simultaneously steer prey towards grouping and dispersing might be required for prey individuals to evolve dynamic parallel movement.

A Stochastic Differential Equation Model for Predator-Avoidance Fish Schooling

This paper presents a system of stochastic differential equations (SDEs) as mathematical model to describe the spatial-temporal dynamics of predator-prey system in an artificial aquatic environment

Animating predator and prey fish interactions

A fish school escape behavior model that can simulate 12 fish escape maneuvers identified in biological studies and can free an animator from dealing with the low‐level animations but instead controls the fish behavior on a higher level by modifying a state machine and a small set of system parameters.

‘Selfish herds’ of guppies follow complex movement rules, but not when information is limited

It is concluded that guppies are able to use complex rules to form dense aggregations, but that environmental factors can limit their ability to do so.

The aim of this work is to use this biologically inspired model along with a robust feedback linearization controller to achieve both target pursuance and effective evasion from two predators.

Evolutionary Impact of Size-Selective Harvesting on Shoaling Behavior: Individual-Level Mechanisms and Possible Consequences for Natural and Fishing Mortality

This work presents a multi-generation harvest selection experiment with zebrafish as a model species and shows that shoal cohesion changed in the direction expected by a trade-off between vigilance and the use of social cues, favoring more cohesive shoals.

Harvesting-induced evolution of collective behavior in a fish

This work presents a multi-generation harvest selection experiment with zebrafish as a model species and demonstrates that large size-selective harvesting typical of global fisheries decreases risk-taking behavior of individuals, and surprisingly also decreases shoal cohesion.

Simulated Predator Attacks on Flocks: A Comparison of Tactics

A fuzzy individual-based model is used to study three attack tactics and analyze the success of predation on two types of prey and revealed that social flocking is the optimal anti-predatory response to predators attacking mainly isolated individuals.

Effects of successive predator attacks on prey aggregations

The results suggest that both aerial and underwater predators are more efficient at disturbing fish schools by increasing their attack frequency at such level that the fish cannot return to swarming/schooling.

Predatory Fish Select for Coordinated Collective Motion in Virtual Prey

It is demonstrated that collective motion could evolve as a response to predation, without prey being able to detect and respond to predators.

Evolution of Swarming Behavior Is Shaped by How Predators Attack

This work corroborates Hamilton's selfish herd hypothesis in a digital evolutionary model, refines the assumptions of the selfish herd hypotheses, and generalizes the domain of danger concept to density-dependent predation.

On prey grouping and predator confusion in artifical fish schools

In two simulation models the benefit of schooling under predatory pressure is investigated. It appears that if a pre dator cannot become confused by prey, grouping is seldom beneficial. If prey,

Critical interplay between density-dependent predation and evolution of the selfish herd

This work verifies Hamilton's selfish herd hypothesis in a digital evolutionary model, refines the assumptions of the selfish herd hypotheses, and generalizes the domain of danger concept to density-dependent predation.

Evolving the selfish herd: emergence of distinct aggregating strategies in an individual-based model

This work suggests that flock or herd formation is likely to be driven by predator avoidance, and adopts an individual-based model for group formation and subject it to simulated predation and foraging; the haploid individuals evolve via a genetic algorithm based on their relative success under such pressure.

Exploring Conditions That Select for the Evolution of Cooperative Group Foraging

Digital organisms are used to study how this decision is made by groups of prey under the threat of predation, with implications for foraging efficiency and fitness.
