The costs and benefits of group membership vary with the size of groups, and individuals
are expected to modify their choice of groups in response to ecological factors such as food …

Polarity, group velocity, and inter-individual spacing are characteristics of fish schools that
strongly affect individual school members. However, these characteristics are group-level …

Animal groups vary in their collective order (or state), forming disordered swarms to highly
polarized groups. One explanation for this variation is that individuals face differential …

Owing to a lack of basic information on the biology of zebrafish (Danio rerio), lab managers
must often base decisions regarding the care and use of this species on anecdotal …

Nature is rich with many different examples of the cohesive motion of animals. Previous
attempts to model collective motion have primarily focused on group behaviours of identical …

Shoaling behaviour has been shown to provide many benefits to group members. In this
study we examined the ability of fish shoals to escape from a novel trawl apparatus. Fish in …

Establishing how collective behaviour emerges is central to our understanding of animal
societies. Previous research has highlighted how universal interaction rules shape collective …

The capability of a new multitracking system to track a large number of unmarked fish (up to
100) is evaluated. This system extrapolates a trajectory from each individual and analyzes …

Zebrafish form shoals in nature and in the laboratory. The sight of conspecifics has been
found reinforcing in zebrafish learning tasks. However, the mechanisms of shoaling, and …

Observations were made on three fish species (banded killifish (Fundulus diaphanus),
golden shiner (Notemigonus crysoleucas) and white sucker (Catostomus commersoni)) in a …
