Symbiont-Mediated Protection of Acromyrmex Leaf-Cutter Ants from the Entomopathogenic Fungus Metarhizium anisopliae [PDF]

mBio, 2021
Many fungus-growing ants engage in a defensive symbiosis with antibiotic-producing ectosymbiotic bacteria in the genus Pseudonocardia, which help protect the ants’ fungal mutualist from a specialized mycoparasite, Escovopsis.

A Haplotype-resolved Chromosome-scale Genome Assembly and Annotation for the Leafcutter Ant, Acromyrmex octospinosus. [PDF]

Genome Biol Evol
Leafcutter ants are ecologically important insects that cultivate fungal gardens for sustenance, playing crucial roles in Neotropical ecosystems. Due to their ecological and evolutionary significance, high-quality genomic assemblies for the species in ...

Two new species of <i>Szelenyiopria</i> Fabritius (Hymenoptera, Diapriidae), larval koinobiont endoparasitoids of the leaf-cutter ant <i>Acromyrmex coronatus</i> (Fabricius) (Hymenoptera, Formicidae), from Panama. [PDF]

Zookeys
Abstract Leaf-cutter ant nests attract a wide variety of guests and parasites due to considerable food resources, substrate and shelter available within nests.

Proteome-Wide Analysis and Surface Protein Isolation for Secretome Characterization Reveal Insights into the Biology of the Leaf-Cutter Ant <i>Acromyrmex echinatior</i>. [PDF]

Anal Chem
Characterizing the proteome of an organism can provide critical insights into the proteins that regulate key biological processes such as development, physiology, and environmental interactions. While proteome-wide analyses reveal broad protein dynamics,

Neural investment patterns reflect task specialization in the leaf-cutting ant <i>Acromyrmex subterraneus</i>. [PDF]

iScience
Summary Leaf-cutting ants are excellent models for studying the relationship between behavior and brain investment because their pronounced division of labor is associated with worker differentiation.

Chromosome Mapping of Ribosomal DNA Clusters in Four Leaf-cutting Ant Species of the Genus Acromyrmex, with Description of a Triploid Individual in A. laticeps

Sociobiology
The increase of cytogenetic data in the leaf-cutting genus Acromyrmex has shown interesting contributions to the evolutionary and taxonomic approaches, including the creation of a new genus and the description of chromosomal patterns allowing ...

Carbon dioxide levels and ventilation in Acromyrmex nests: significance and evolution of architectural innovations in leaf-cutting ants. [PDF]

R Soc Open Sci, 2021
Leaf-cutting ant colonies largely differ in size, yet all consume O2 and produce CO2 in large amounts because of their underground fungus gardens. We have shown that in the Acromyrmex genus, three basic nest morphologies occur, and investigated the ...

Fungus For Fungus: Acromyrmex rugosus (Hymenoptera: Formicidae) collecting on Gymnopilus cf. peliolepis (Agaricales: Hymenogastraceae) in a Brazilian dry forest

Acta Zoológica Lilloana
This short note is a report of Acromyrmex rugosus collecting a slice of mushroom during its foraging. This behavior was already described for other Acromyrmex species, but our register of A. rugosus collecting Gymnopilus cf.

Niche Shifts Induce Major Changes in the Ranges of the World's Worst Invasive Ant Species. [PDF]

Ecol Evol
We detected strong positive associations between their niche and range shifts. Small niche shifts induced large range shifts in them. ABSTRACT Invasive ants have exerted major effects on global ecosystems and economic systems. Therefore, their future niche and range shifts have received more research attention; however, the shifts between their native ...
