Modulation of trail laying in the ant Lasius niger (Hymenoptera: Formicidae) and its role in the collective selection of a food source
TLDR
Simulations of this model showed that the observed modulation of trail laying with respect to food source quality is sufficient in itself to account for the systematic selection of the richer source seen in the experiments.Abstract:
Foragers of the ant Lasius nigerexploiting a 1 Msugar source were found to lay 43 %more trail marks than those exploiting a 0.05 or a 0.1 Msource. The trail laying per forager decreased during the course of individual recruitment episodes, and the mean lifetime of the trail pheromone was estimated to be 47 min. A mathematical function describing the probability that a forager chooses one of two paths in relation to the amount of trail pheromone on them closely fitted experimental data. These results were incorporated into a model describing the recruitment dynamics of L. niger.Simulations of this model showed that the observed modulation of trail laying with respect to food source quality is sufficient in itself to account for the systematic selection of the richer source seen in the experiments.read more

Emergent collective decisions in a swarm of robots
Vito Trianni,Marco Dorigo +1 more
TL;DR: This work presents a task in which a swarm of physically connected, simulated robots has to take a decision whether to pass over a trough or change direction of motion if the gap is too wide to be bridged, and shows how such a decision can be collectively taken, based only on a self-organising process.

Decentralized control of drone comb construction in honey bee colonies
TL;DR: Findings show that drone comb regulation does not depend on the queen acting as a centralized information gatherer and behavioral controller, instead, the evidence points to a decision-making process distributed across the population of worker bees, a control architecture typical of colony organization in honey bees and other large-colony insect societies.

Private information alone can trigger trapping of ant colonies in local feeding optima.

TL;DR: It is found that private information is sufficient to trigger trapping in selecting the poorer of two food sources, and may be sufficient to cause it altogether, even when pheromone trails are removed.

U-turns on ant pheromone trails
Adam G. Hart,Duncan E. Jackson +1 more
TL;DR: It is found that a minority of ants consistently make frequent and seemingly inappropriate U-turns during foraging bouts, and this data suggest that U- turning ants make a greater contribution to trail persistence than do non-turners.

TL;DR: The effect of protein to carbohydrate ratio on ants' ability to detect and choose between foods with different protein characteristics (free amino acids or whole proteins) is explored.

The self-organizing exploratory pattern of the argentine ant
TL;DR: A minimal model shows how the exploratory pattern may be generated by the individual workers' simple trail-laying and -following behavior, illustrating how complex collective structures in insect colonies may be based on self-organization.

Collective decision-making in honey bees: how colonies choose among nectar sources
TL;DR: It is suggested that honey bee colonies possess decentralized decision-making because it combines effectiveness with simplicity of communication and computation within a colony.

Trails and U-turns in the Selection of a Path by the Ant Lasius niger
TL;DR: The selection of the path is shown to be a collective process whereby trail laying and following amplifies small initial differences in the traffic on each path caused by these three mechanisms, and the foragers show no significant tendency to follow the path they used previously.

Collective decision making through food recruitment
TL;DR: A series of experiments shows how the andLasius niger uses its trail recruitment system to select between two food sources, simultaneously presented with to 1M sucrose solution and when offered a 1M solution together with a 0.1M solution.

TL;DR: In this article, the authors present a model that describes the honey bee colony's decision-making process, which consists of a system of non-linear differential equations describing the activity of the foraging bees.
