Evolutionary Conditions for the Emergence of Communication in Robots

Dario Floreano, Stéphane Magnenat, Laurent Keller, Sara Mitri

Information transfer plays a central role in the biology of most organisms, particularly social species [1, 2]. Although the neurophysiological processes by which signals are produced, conducted, perceived, and interpreted are well understood, the conditio ...

Differential gene expression between adult queens and workers in the ant Lasius niger

Johannes Gräff, Laurent Keller

Ants and other social insects forming large societies are generally characterized by marked reproductive division of labour. Queens largely monopolize reproduction whereas workers have little reproductive potential. In addition, some social insect species ...

An annotated cDNA library and microarray for large-scale gene-expression studies in the ant Solenopsis invicta

Johannes Gräff, Laurent Keller

Ants display a range of fascinating behaviors, a remarkable level of intra-species phenotypic plasticity and many other interesting characteristics. Here we present a new tool to study the molecular mechanisms underlying these traits: a tentatively annotat ...

Division of labour and colony efficiency in social insects: effects of interactions between genetic architecture, colony kin structure and rate of perturbations

Dario Floreano, Stéphane Magnenat, Laurent Keller, Markus Waibel

The efficiency of social insect colonies critically depends on their ability to efficiently allocate workers to the various tasks which need to be performed. While numerous models have investigated the mechanisms allowing an efficient colony response to ex ...

Influence of the level of polyandry and genetic architecture on division of labour

Dario Floreano, Laurent Keller

Genetic diversity is thought to be a main factor in determin ing task performance and behavioral plasticity of social insect colonies. This diversity has two main causes. a) Multiple matings by the colony queen (polyandry) and b) the number of regions on t ...
