Harnessing Molecular and Bioactivity Network Analysis to Prioritize Antibacterial Compound Isolation From Ant-Associated Fungi. [PDF]

open access: yesPhytochem Anal
ABSTRACT Introduction Antimicrobial resistance is a global public health problem that requires the development of new bioactive compounds. In this context, metabolomic analyses can expedite the research of fungal metabolites as a valuable resource. Objectives To investigate the metabolic profiles and isolate antibacterial compounds from micromycetes ...

The Metapleural Secretion of Acromyrmex laticeps (Forel) does not have Fungicide Effect on the Entomopathogenic Fungus Beauveria bassiana (Bals.) Vuill

open access: yesEntomoBrasilis, 2014
The metapleural gland (MPG) is an exocrine structure, exclusive to formicids, being more developed in females and workers. This structure is stunted or nonexistent in males.

New Light on the Systematics of Fungi Associated with Attine Ant Gardens and the Description ofᅠEscovopsis kreiseliiᅠsp. nov. [PDF]

open access: yes, 2015
Since the formal description of fungi in the genus Escovopsis in 1990, only a few studies have focused on the systematics of this group. For more than two decades, only two Escovopsis species were described; however, in 2013, three additional Escovopsis ...

Generation of Nutrients and Detoxification: Possible Roles of Yeasts in Leaf-Cutting Ant Nests

open access: yesInsects, 2012
The possible roles played by yeasts in attine ant nests are mostly unknown. Here we present our investigations on the plant polysaccharide degradation profile of 82 yeasts isolated from fungus gardens of Atta and Acromyrmex species to demonstrate that ...

Specialized Fungal Parasites and Opportunistic Fungi in Gardens of Attine Ants

open access: yesPsyche: A Journal of Entomology, 2012
Ants in the tribe Attini (Hymenoptera: Formicidae) comprise about 230 described species that share the same characteristic: all coevolved in an ancient mutualism with basidiomycetous fungi cultivated for food. In this paper we focused on fungi other than

Group-wise 3D registration based templates to study the evolution of ant worker neuroanatomy [PDF]

open access: yes, 2017
The evolutionary success of ants and other social insects is considered to be intrinsically linked to division of labor and emergent collective intelligence.

Symbiont choice in a fungus-growing ant (Attini, Formicidae) [PDF]

open access: yesBehavioral Ecology, 2004
Cultivars of fungus-growing (attine) ants are vertically transmitted through inheritance from parent to offspring nest, but horizontal cultivar transfer between ant nests occurs occasionally, resulting in cultivar replacement within ant lineages. Two mechanisms could theoretically prevent the invasion of suboptimal cultivar strains and thus stabilize ...
