Infrastructure investment in leaf-cutter ants Atta

2017
Large-scale collective infrastructure construction is only known in two groups of animals: humans and social insects. Leaf-cutter ants construct networks of cleared trails spanning several kilometres, from which they remove all organic litter and undergrowth. Little research exists on their function or on how they are constructed.

Leaf-cutter ant assemblies: effects of latitude, vegetation, and behaviour

1991
Abstract Although leaf-cutter ants (Acromyrex and Atta) are commonly considered to be characteristic of tropical forests, leaf-cutters are actually more abundant and diverse in the subtropics of South America (Fowler 1983a,b) (Fig. 5.1). Due to this biogeographical pattern, co-occurrences of taxa are likely, especially in the subtropical

Resource quality and cost in the foraging of leaf-cutter ants

1991
Abstract Leaf-cutter ant colonies may contain over a million workers and a thousand fungus gardens (Weber 1972), and to support these large colonies the ants continually search out and harvest suitable plants. However, ant colonies face limits to their ability to locate and harvest resources efficiently.

The biomechanics and energetics of foraging in leaf-cutter ants

In this thesis, I investigate the mechanical and energetic constraints of leaf cutting—a key aspect of insect herbivore foraging behaviour—using highly polymorphic leaf-cutter ants Atta cephalotes as a model system. I begin by exploring the factors that influence insect herbivory through the lens of fracture mechanics.
