Reciprocal genomic evolution in the ant–fungus agricultural symbiosis

Nature Communications, 2016
Attine ants, including the leaf-cutting ants, cultivate fungi as their sole source of food. Here, Nygaard et al. use whole genome and transcriptome sequences from seven ant species and their fungal cultivars to reconstruct the reciprocal genetic changes ...

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

Acta 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

Mutualistic interactions between ants and fungi: A review

Ecology and Evolution, 2023
The large amount of dead plant biomass caused by the final extinction events triggered a fungi proliferation that mostly differentiated into saprophytes degrading organic matter; others became parasites, predators, likely commensals, and mutualists ...

Fungal-Fungal Interactions in Leaf-Cutting Ant Agriculture

Psyche: A Journal of Entomology, 2011
Many organisms participate in symbiotic relationships with other organisms, yet studies of symbioses typically have focused on the reciprocal costs and benefits within a particular host-symbiont pair.

From Plants to the Fungus Garden: Physical, Chemical, and Behavioral Factors Influencing Foraging in Leaf-Cutting Ants [PDF]

Brazilian Journal of Biology
Leaf-cutting ants selectively forage plant material to cultivate their symbiotic fungus, Leucoagaricus gongylophorus, which constitutes the primary food source for their colonies.

Influência da espécie cultivada e da vegetação nativa circundante na densidade de sauveiros em eucaliptais Influence of the cultivated species and of the native vegetation on leaf-cutting ant nests density in eucalyptus plantations

Pesquisa Agropecuária Brasileira, 2000
Este estudo foi realizado em reflorestamentos com eucalipto da V & M Florestal Ltda., em João Pinheiro, MG. O objetivo foi verificar o efeito da espécie de eucalipto cultivada, da idade da planta, assim como da vegetação nativa que circunda os talhões ...

Atratividade de Atta sexdens rubropilosa por plantas de eucalipto atacadas previamente ou não por Thyrinteina arnobia Atta sexdens rubropilosa attractiveness to eucalyptus plants previously attacked or not by Thyrinteina arnobia

Pesquisa Agropecuária Brasileira, 2004
O sistema de defesa induzido das plantas é ativado após a ocorrência do dano provocado por um herbívoro. O objetivo deste trabalho foi avaliar se plantas de eucalipto (Eucalyptus grandis) atacadas previamente por lagartas de Thyrinteina arnobia tornam-se

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.
