Ant colonies are highly-organized societies without central control. Due to their impressive diversity, ants offer the opportunity to comparatively analyze the mechanisms underlying individual behavior, the coordination of social responses, as well as the adaptive significance of a given set of behavioral strategies. Our research is aimed, in a broad sense, at understanding the organization of ant societies. We investigate individual decision making, behavioral plasticity, information flows, division of labor, and collective behaviors in ant colonies, in the contexts of food collection, nest building, and the control of nest climate. Leaf-cutting ants and nectar-feeding ants are our research animals.
- Decision-making and information flow in foraging leaf-cutting ants.
- Energetics of decision-making in ants: costs of foraging and digging behavior.
- Feeding behavior, communication, and the organization of foraging in nectar-feeding ants.
- Building behavior and the control of nest climate in leaf-cutting ants.
