Collective memory and spatial sorting in animal groups.
We present a self-organizing model of group formation in three-dimensional space, and use it to investigate the spatial dynamics of animal groups such as fish schools and bird flocks. We reveal theExpand

Effective leadership and decision-making in animal groups on the move
For animals that forage or travel in groups, making movement decisions often depends on social interactions among group members. However, in many cases, few individuals have pertinent information,Expand

From Disorder to Order in Marching Locusts
Recent models from theoretical physics have predicted that mass-migrating animal groups may share group-level properties, irrespective of the type of animals in the group. One key prediction is thatExpand

Self-Organization and Collective Behavior in Vertebrates
Publisher Summary The chapter discusses an emerging area of study: that of applying self-organization theory to mobile vertebrate groups composed of many interacting individuals such as bird flocks,Expand

Inferring the structure and dynamics of interactions in schooling fish
Determining individual-level interactions that govern highly coordinated motion in animal groups or cellular aggregates has been a long-standing challenge, central to understanding the mechanisms andExpand

Inherent noise can facilitate coherence in collective swarm motion
Among the most striking aspects of the movement of many animal groups are their sudden coherent changes in direction. Recent observations of locusts and starlings have shown that this directionalExpand

Automated image-based tracking and its application in ecology.
The behavior of individuals determines the strength and outcome of ecological interactions, which drive population, community, and ecosystem organization. Expand

Quorum decision-making facilitates information transfer in fish shoals
Despite the growing interest in collective phenomena such as “swarm intelligence” and “wisdom of the crowds,” little is known about the mechanisms underlying decision-making in vertebrate animalExpand

Collective States, Multistability and Transitional Behavior in Schooling Fish
We demonstrate that collective motion can be effectively mapped onto a set of order parameters describing the macroscopic group structure, revealing the existence of at least three dynamically-stable collective states; swarm, milling and polarized groups. Expand
