Phylogenomics of Messor harvester ants (Hymenoptera: Formicidae: Stenammini) unravels their biogeographical origin and diversification patterns La phylogénomique des fourmis moissonneuses Messor (Hymenoptera: Formicidae: Stenammini) clarifie leur origine biogéographique et leurs patrons de diversification

open access: yesSystematic Entomology, Volume 50, Issue 4, Page 1025-1040, October 2025.
Phylogenomic analysis of 2524 ultraconserved‐element loci from 58 Messor harvester ant species helps in redefining taxonomic groups of the genus. Messor ants emerged in the Irano‐Indian area around 20 million years ago, rapidly dispersing to the Western Palaearctic and Northeastern Africa during the early Miocene.

Different Aspects of Dominance Are Not Equivalent When Testing for Trade‐Offs in Ant Communities

open access: yesEcology and Evolution, Volume 15, Issue 9, September 2025.
Dominance hierarchies are often invoked to explain the outcomes of competition across ecological communities. However, there are a number of difficulties associated with quantifying dominance, making it is challenging to ultimately link dominance to community structure and species coexistence. Here we provide evidence, both empirically and through meta‐

A zoogeographic model for the evolution of diversity and endemism in Madagascar

open access: yesEcography, Volume 2025, Issue 8, August 2025.
The delineation of zoogeographic regions is essential for understanding the evolution of biodiversity. Madagascar, characterized by high levels of endemism and habitat diversity, presents unique challenges and opportunities for such studies. Traditional global zoogeographic classifications, largely based on vertebrates, may overlook finer‐scale ...

Monitoreo de la reserva natural Paititi mediante el uso de grupos funcionales de hormigas (Hymenóptera: Formicidae), Buenos Aires, Argentina [PDF]

open access: yes, 2017
La utilización de hormigas en programas de monitoreo es muy escasa. La excepción es Australia, en donde éstas se han utilizado exitosamente durante años como indicadoras en la recuperación de sitios impactados por la industria minera principalmente.
