Genetic polyethism in leaf-cutting ants [PDF]

open access: yesBehavioral 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.

The interplay between a self-organized process and an environmental template: corpse clustering under the influence of air currents in ants [PDF]

open access: yes, 2007
Many spatial patterns observed in nature emerge from local processes and their interactions with the local environment. The clustering of objects by social insects represents such a pattern formation process that can be observed at both the individual ...

Dump size and distance from the nest define the investment in waste management in Sericomyrmex mayri (Formicidae: Myrmicinae: Attini)

open access: yesEcología Austral, 2020
The farming system practiced by non-leaf-cutting ants Sericomyrmex mayri (Formicidae: Myrmicinae: Attini) involves a mutualistic interaction with symbiotic fungi.

Leaf-cutting ant attack in initial pine plantations and growth of defoliated plants

open access: yesPesquisa 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

Influências de Atta spp. (Hymenoptera: Formicidae) na recuperação da vegetação pós-fogo em floresta de transição amazônica Influences of leafcutter ant Atta spp. (Hymenoptera: Formicidae) on vegetation recovery after fire in Amazonian transitional forest

open access: yesActa Amazonica, 2012
Este estudo investigou o papel das saúvas na recuperação da vegetação pós-fogo. Foi hipotetizado que a perturbação do fogo aumenta a abundância de ninhos de saúva (1) e as atividades de remoção de sementes (2) e desfolha (3), especialmente no ambiente de

Nonhuman Complexity Poetics: Leaf-Cutter Ants and Multispecies Composition

open access: yes, 2022
In this article I examine leaf-cutter ants, and particularly their nest architecture, in terms of what I call an ‘ethological poetics.’ I propose that thinking about leaf-cutter architecture is an engagement with a radically alternative aesthetics.

Laccase detoxification mediates the nutritional alliance between leaf-cutting ants and fungus-garden symbionts

open access: yes, 2013
Leaf-cutting ants combine large-scale herbivory with fungus farming to sustain advanced societies. Their stratified colonies are major evolutionary achievements and serious agricultural pests, but the crucial adaptations that allowed this mutualism to ...

Trichome Removal by Hitchhikers in Two Leaf-cutting Ant Species (Hymenoptera: Formicidae)

open access: yesSociobiology, 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

A single Streptomyces symbiont makes multiple antifungals to support the fungus farming ant Acromyrmex octospinosus

open access: yes, 2013
Attine ants are dependent on a cultivated fungus for food and use antibiotics produced by symbiotic Actinobacteria as weedkillers in their fungus gardens. Actinobacterial species belonging to the genera Pseudonocardia, Streptomyces and Amycolatopsis have
