Gregarious animals need to make collective decisions in order to keep their cohesiveness. Several species of them live in multilevel societies, and form herds composed of smaller communities. We present a model for the development of a leadership hierarchy in a herd consisting of loosely connected sub-groups (e.g. harems) by combining self organization and social dynamics. It starts from unfamiliar individuals without relationships and reproduces the emergence of a hierarchical and modular… 

CoFee-L: A Model of Animal Displacement in Large Groups Combining Cohesion Maintenance, Feeding Area Search and Transient Leadership

Simple Summary In the current context of climate change and forest cover degradation, the dispersal potential of trees is an issue of great importance. This is particularly the case in the tropics,

Behavioural synchronization in a multilevel society of feral horses

TLDR
This result suggests that animals in a multilevel society coordinate with other conspecifics not only within a unit but at an inter-unit level.

Observing the unwatchable: Integrating automated sensing, naturalistic observations, and animal social network analysis in the age of big data.

TLDR
While technological advances in automating data collection and its analysis are moving at an unprecedented rate, it is urged ecologists to thoughtfully combine these new tools with classic behavioural and ecological monitoring methods to place the understanding of animal social networks within fundamental biological contexts.

Market of Stocks during Crisis Looks Like a Flock of Birds

TLDR
The findings show that the direction of the resultant velocity vectors of all share in this phase space act in the same direction when the financial crisis happens.

A mathematical model of herding in horse-harem group

TLDR
A mathematical model of mares herded by a harem stallion is proposed, which is a modification of a sheep model during shepherding and successfully reproduce the movements and directional trends of the mares.

Finding continuity and discontinuity in fish schools via integrated information theory

TLDR
The application of integrated information theory to the analysis of real fish schools suggests that integrated information Φ can reveal the emergence of a new type of leadership which cannot be observed using other measures.

Hierarchy Measure for Complex Networks

TLDR
This work develops an approach and proposes a quantity (measure) which is simple enough to be widely applicable, reveals a number of universal features of the organization of real-world networks and is capable of capturing the essential Features of the structure and the degree of hierarchy in a complex network.

Hierarchical Self-Organization of Non-Cooperating Individuals

TLDR
This work introduces an approach which is capable of reproducing the emergence of a multi-levelled network structure based on the plausible assumption that the individuals (representing the nodes of the network) can make the right estimate about the state of their changing environment to a varying degree.

This book presents the results of an eighteen-month field study of wild hamadryas baboons. The author attempts to interpret his findings in terms of the bonding-stage model of Hans Kummer and

Natural and sexual selection and the evolution of multi-level societies: insights from zebras with comparisons to primates

TLDR
This chapter begins by highlighting the environmental and sociosexual factors that shape zebra mating systems and herd dynamics, and examines how natural and sexual selection operate within multi-level societies.

Fast and Accurate Decisions as a Result of Scale-Free Network Properties in Two Primate Species

TLDR
It is shown that individuals that are central to the group’s social network elicit stronger follower behaviour and are crucial to the achievement of consensus decisions, and that a behavioural rule-of-thumb ‘follow my close affiliate’ can result in the most central individual leading decisions by virtue of the scale-free properties of the network.

Decision-Making in Przewalski Horses (Equus ferus przewalskii) is Driven by the Ecological Contexts of Collective Movements

TLDR
The decision-making in Przewalski horses is based on a shared consensus process driven by ecological determinants, which demonstrates that the horses need more time to resolve motivational conflicts before these departures.
