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

Evolutionary stability of social interaction rules in collective decision-making
Fagang Zhong,Gengxin Ning +1 more
TL;DR: In this article , the authors explore the performance of one commonly used decision making rule in terms of the expected decision accuracy of individuals employing it and show that parameters of this model obey necessary relationships under the assumption that animals are evolutionarily optimised to their environment.
Nonlinear phenomena and resource exploitation in group living organisms
TL;DR: A mathematical model of food recruitment in ants in the presence of communicating sources is developed and the aim is to analyze the effect of traffic between the sources using mean field approximation.

The impact and spread of the invasive garden ant: an alien invasive species in the UK
TL;DR: In this paper, the authors carried out a UK-wide risk assessment for the invasive garden ant Lasius neglectus and developed a protocol for experimentally assessing its potential impact on an economically important crop plant.

Ants prefer the option they are trained to first
TL;DR: In this article , the authors trained Lasius niger ants to make multiple visits to sucrose on a runway which alternated between lemon or rosemary odour, and then tested for preference between the odours on a Y-maze, in order to investigate the effect of pheromone presence on learning.
An information market for social navigation in robot swarms
TL;DR: This work designs two protection mechanisms for an information market where robots can buy and sell information through transactions stored on a distributed blockchain, and where cooperation is encouraged by the economy itself.

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.
