Current Biology, PNAS: Cannibalism and collective behavior in swarming insects

Posted by in Headlines No comment

One of the most striking and devastating examples of collective movement is exhibited by locusts. Swarms of the desert locust, Schistocerca gregaria, can devour large areas of vegetation and have a huge social and economic impact on humans, affecting the livelihood of one in ten people on the planet in plague years. How do these […]

Collective Motion and Decision-Making in Animal Groups

Posted by in Uncategorized No comment

By accessing social cues individuals, who may themselves be limited in sensory range and cognitive capacity, can access higher-order computational capabilities. We have previously shown, in a paper in Nature, how directional information can be effectively disseminated within groups, facilitating both ad-hoc leadership and consensus decision-making even in the absence of signaling or individual recognition. […]

High performance computing for massively parallel simulations of animal group behavior

Posted by in Uncategorized 2 comments

We develop our massively parallel simulation models of animal group behavior using General Purpose Graphics Processing Units (GPGPUs) and NVIDIA’s CUDA programming architecture (and sometimes OpenCL). This high performance computing environment allows us to harness thousands of processing cores allowing us to simulate millions of interacting individuals in complex environments as well as to explore […]

Pheromone trail networks in ants

Posted by in Uncategorized 6 comments

Among the everyday challenges an ant colony faces, the exploration and the exploitation of its environment is one of the most critical. In some species food collection is achieved by thousands of workers travelling along well-defined foraging trails. These trails emerge from a succession of pheromone deposits and can result in a complex network of interconnected routes. […]
