Food Hoarding in Animals
In this first comprehensive synthesis of the literature on food hoarding in animals, Stephen B. Vander Wall discusses how animals store food, how they use food and how this use affects individual fitness, and provides detailed coverage of hoarding behavior across taxa-mammals, birds, and arthropods.
Collective memory and spatial sorting in animal groups.

The first evidence for collective memory is presented in such animal groups (where the previous history of group structure influences the collective behaviour exhibited as individual interactions change) during the transition of a group from one type of collective behaviour to another.
Effective leadership and decision-making in animal groups on the move
It is revealed that the larger the group the smaller the proportion of informed individuals needed to guide the group, and that only a very small proportion ofinformed individuals is required to achieve great accuracy.

Social Evolution in Ants
An overview of the current state of scientific knowledge about social evolution in ants is presented and how studies on ants have contributed to an understanding of many fundamental topics in behavioural ecology and evolutionary biology is shown.

A distributed sorting algorithm, inspired by how ant colonies sort their brood, is presented for use by robot teams, offering the advantages of simplicity, flexibility and robustness.

This work shows that Leptothorax albipennis ants can lower their quorum thresholds between benign and harsh conditions to adjust their speed–accuracy trade–off, and that in harsh conditions these ants rely much more on individual decision making than collective decision making.
Teams in animal societies
It is predicted that teams in insect societies are more likely to be found in large polymorphic (‘‘complex’’) societies than in small monomorphic societies, and a new rigorous definition of a team is proposed that may be applied to both vertebrate and invertebrate societies.
A Mechanism for Value-Sensitive Decision-Making

A dynamical systems analysis of a decision-making mechanism inspired by collective choice in house-hunting honeybee swarms reveals the crucial role of cross-inhibitory ‘stop-signalling’, and proposes that the model, and the significant role of the values of the alternatives, may describe other decision- Making systems, and may provide guidance in the design of decision- making algorithms for artificial systems.
Quorum sensing, recruitment, and collective decision-making during colony emigration by the ant Leptothorax albipennis

A model shows that the quorum requirement can help a colony choose the best available site, even when few ants have the opportunity to compare sites directly, because recruiters to a given site launch the rapid transport of the bulk of the colony only if enough active ants have been "convinced" of the worth of the site.
