Abstract: | It is often assumed that learning improves foraging, but its direct benefits are not often examined. We demonstrate the contribution of learning to the foraging success of desert ants when a trained colony successfully competes against a naïve one. The outcome also depends on the relative group size. Desert Cataglyphis ants search individually for food (mostly dead prey) without laying pheromone trails (see pages 241-250). The cover photo shows a Cataglyphis niger worker searching for food in its typical sandy habitat. Photo provided Arik Dorfman. |
