The Effect of nest Size and Species Identity on Plant Selection in Acromyrmex Leaf-Cutting Ants
Sociobiology, 2018 Leaf-cutting ants are key organisms because their role as primary consumers and potential agricultural pests. However, their foraging ecology was mostly studied as response of extrinsic factors such as climate and plant species traits.

Genetic polyethism in leaf-cutting ants [PDF]
Behavioral Ecology, 2010 Females mating with multiple males (polyandry) is taxonomically widespread but is hard to explain in many animals in which it has no obvious direct benefits. In some, of which social insects are the best example, it is suggested that females benefit from the increased genetic diversity of their offspring.

Leaf-cutting ant attack in initial pine plantations and growth of defoliated plants
Pesquisa Agropecuária Brasileira, 2012 The objective of this work was to evaluate the natural attack by Acromyrmex crassispinus in initial Pinus taeda plantations without control measures against ants, as well as the effect of defoliation in seedlings of P. taeda. Evaluations of the attack of

Reproduction of leaf-cutting ant workers: breaking the queen monopoly [PDF]
Brazilian Journal of BiologyThe complex colony organization with labor division, age polyethism and polymorphism, specialized tasks among younger and older workers, subdivision into subcastes, and the cultivation of symbiotic fungus as the primary food source, distinguishes leaf ...

Waveguide Photoactuators: Materials, Fabrication, and Applications
Advanced Robotics Research, EarlyView.Waveguide photoactuators convert guided light into mechanical motion. Their tethered‐flexible design enables minimally invasive surgery and confined‐space robotics. This review aims to guide materials selection, device design, and system integration, accelerating the transition of waveguide photoactuators from laboratory prototypes to versatile ...

Trichome Removal by Hitchhikers in Two Leaf-cutting Ant Species (Hymenoptera: Formicidae)
Sociobiology, 2014 Despite the known evidence that hitchhiker ants protect workers against attack by phorid parasitoids, several alternative hypotheses are suggested for the occurrence of hitchhikers on leaf-cutting ants. One hypothesis suggests that hitchhikers clean leaf
