Leaf-Cutting Ants (Atta cephalotes) Select Nitrogen-Rich Forage
American Midland Naturalist, 1986Two colonies of the leaf-cutting ant (Atta cephalotes L.) at Turrialba, Costa Rica, foraged on a restricted subset of the total available plant species, generally preferring introduced cultivars over native plants, but sampling many early successional species. Feeding preferences were related to elemental composition of leaves.

On Nest Densities of the Leaf-Cutting Ant Atta cephalotes in Tropical Primary Forest
Biotropica, 1989Atta nest densities in six undisturbed primary rain forest ecosystems in the Orinoco-Amazon basin have been estimated. The only species encountered was Atta cephalotes which occurred at a maximal density of 0.045 nests per ha. Three possible explanations for these low densities in contrast to those found in disturbed habitats are discussed.

Morphology and Mechanical Properties of Vibratory Organs in the Leaf-cutting Ant (Atta cephalotes)
Journal of Bionic Engineering, 2018The ultrasonic scalpel has a number of excellent properties; however, its use in in vivo surgery is limited since the scalpel is not flexible enough. Changing the mechanism of ultrasonic vibration can allow the ultrasonic scalpel to bend. This paper reveals the mechanism of vibration generation of leaf-cutting ants, which is based on the ...

Leaf‐Cutter Ant (Atta cephalotes) Influence on the Morphology of Andepts in Costa Rica
Soil Science Society of America Journal, 1981Abstract Twenty‐seven soil profiles distributed within a 2.5‐ha site were described as Typic Dystrandepts of the Colorado soil series. Leaf‐cutter ant influence was noted in 85% of the pedons. The influence on each profile was estimated, and out of all profiles, 37% had low, 26% medium, and 22% high disturbance ...

In the leaf-cutting ant Atta cephalotes (L.) small colonies produce a relatively narrow size-range of small workers, whereas large colonies produce a much wider size-range of workers. In this study, I compared the foraging of four small A. cephalotes colonies (fewer than 5000 workers) with published data on foraging of large colonies to examine how ...
