Development and characterization of twenty-two polymorphic microsatellite markers for the leafcutter ant, Acromyrmex lundii, utilizing Illumina sequencing
(Springer, 2014-06-01)
We isolated and characterized a total of 22 microsatellite loci for the leafcutter ant, Acromyrmex lundii. The loci were screened for 24 individuals from southern Brazil and Uruguay. The number of alleles per locus ranged ...
Biogeography of mutualistic fungi cultivated by leafcutter ants
(Wiley-Blackwell, 2017-12-01)
Leafcutter ants propagate co-evolving fungi for food. The nearly 50 species of leafcutter ants (Atta, Acromyrmex) range from Argentina to the United States, with the greatest species diversity in southern South America. ...
Variation in nest morphology, queen oviposition rates, and fungal species present in incipient colonies of the leaf-cutter ant Atta sexdens
(2019-04-03)
The success of incipient colonies of leaf-cutter ants depends on multiple factors such as temperature, humidity, soil type, the queen’s fertility and vigor, frequency of harmful microfungi, among others. Based on this ...
Phylogenetic patterns of ant-fungus associations indicate that farming strategies, not only a superior fungal cultivar, explain the ecological success of leafcutter ants
(Wiley-Blackwell, 2018-05-01)
To elucidate fungicultural specializations contributing to ecological dominance of leafcutter ants, we estimate the phylogeny of fungi cultivated by fungus-growing (attine) ants, including fungal cultivars from (i) the ...
Communication or toxicity: What is the effect of cycloheximide on leaf-cutting ant workers?
(2017-12-01)
Leaf-cutting ants are insects that use plant material to grow fungus from which they feed. These fungus-growing ants perform various behavioral activities to establish an environment conducive to the fungus. Among these ...
Soluble Compounds of Filamentous Fungi Harm the Symbiotic Fungus of Leafcutter Ants
(2018-01-01)
Chemical compounds are key to understand symbiotic interactions. In the leafcutter ant-microbe symbiosis a plethora of filamentous fungi continuously gain access the ant colonies through plant substrate collected by workers. ...
Escovopsioides as a fungal antagonist of the fungus cultivated by leafcutter ants
(2018-10-10)
Background: Fungus gardens of fungus-growing (attine) ants harbor complex microbiomes in addition to the mutualistic fungus they cultivate for food. Fungi in the genus Escovopsioides were recently described as members of ...
