About the Project
Division of labour, whereby different tasks are carried out by different groups of workers, is often considered one of the main drivers of the ecological success of social insects (ants, bees, wasps & termites), because specialisation into tasks is predicted to increase performance and minimise task-switching costs. However, the evidence that division of labour does increase productivity in social insects is equivocal. Furthermore, most studies have been carried out using unrealistically simple experimental nests, thus ignoring a key benefit of division of labour: the effective organization of tasks in space, to optimise the flow of work from task to task and minimise interference between unrelated tasks. This project aims to investigate the synergies between nest architecture, division of labour and group-level productivity using ant colonies as a model system. The project will use a broad range of cutting-edge techniques for experimental manipulation (laser-cutting and 3D-printing of 2D- and 3D- experimental nests; access control using barcode-operated gates), data recording (automated barcode-based individual tracking; raspberry-pi controlled video recording) and analysis (custom code to analyse big data, network analysis). This project may uncover previously overlooked key aspects of ergonomic work organisation in societies occupying complex built structures, and so pave the way towards new bio-inspired principles for efficient and resilient architectural design.
