Ecological Monographs, Volume 93, Issue 1, February 2023., 2023 Abstract Sustaining beneficial gut symbioses presents a major challenge for animals, including holometabolous insects. Social insects may meet such challenges through partner fidelity, aided by behavioral symbiont transfer and transgenerational inheritance through colony founders.

Biological Reviews, Volume 97, Issue 4, Page 1559-1611, August 2022., 2022 ABSTRACT In a much‐cited 1964 paper entitled “Reproductive efficiency in relation to colony size in hymenopterous societies,” Charles Michener investigated the correlation between a colony's size and its reproductive efficiency – the ability of its adult females to produce reproductives, measured as per‐capita output. Based on his analysis of published

Distinct and enhanced hygienic responses of a leaf‐cutting ant toward repeated fungi exposures
Ecology and Evolution, Volume 12, Issue 7, July 2022., 2022 The leaf‐cutting ant Atta sexdens discriminates between different antagonistic fungi and apply distinct responses to remove them from the fungus garden. Also, successive exposures to the same antagonist increase sanitization in the fungus garden.

PLoS ONE, 2014 Attine ants cultivate fungi as their most important food source and in turn the fungus is nourished, protected against harmful microorganisms, and dispersed by the ants.

Systematic Entomology, Volume 47, Issue 1, Page 13-35, January 2022., 2022 We employ phylogenomic markers (UCEs) to reconstruct the most extensively sampled phylogeny to date for the ecologically dominant leaf‐cutting ant genus Atta, the major herbivore of the New World tropics. The ancestor of Atta arose 8.5 Ma in the North/Central America + NW South America range, and its descendant species rapidly radiated into Neotropical

Ecology and Evolution, Volume 11, Issue 24, Page 17686-17699, December 2021., 2021 In leaf‐cutting ant pests, an obligate mutualistic basidiomycete mediates the ants’ nutrition with carbons from vegetal matter using a fermenter‐like system inside the nest, called a “fungus garden.” Diazotrophs such as Enterobacteriales in the fungus garden and intestinal Rhizobiales were proposed to mediate the incorporation of atmospheric nitrogen ...

Ecology and Evolution, Volume 11, Issue 11, Page 6041-6052, June 2021., 2021 We studied two sympatric Apterostigma fungus‐growing ants (Attini) species and their symbiotic fungal cultivars which are attacked by multiple morphotypes of parasitic fungi in the genus, Escovopsis. We assessed in vitro and in vivo interactions of these parasites with their hosts to understand, in the context of a multihost, multiparasite system, the ...

New light on the systematics of fungi associated with attine ant gardens and the description of Escovopsis kreiselii sp. nov. [PDF]
PLoS ONE, 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 ...

Forel ants and their fungal cultivars provide insights into the origin and coevolutionary history of ‘higher‐attine’ ant agriculture [PDF]
, 2019 The fungus‐growing ants and their fungal cultivars constitute a classic example of a mutualism that has led to complex coevolutionary dynamics spanning c. 55–65 Ma.
