Nuevas especies de hormigas

open access: yesActa Zoológica Lilloana, 2022
Poco antes de su muerte, el Dr. N. Kuznetsov estaba trabajando en un artículo sobre hormigas argentinas, en el que recopiló los datos biológicos de la mayoría de las especies y al mismo tiempo describió 6 especies nuevas. En sus manuscritos preliminares,

Chromosomal Diversity as a Predictor of Lineage Diversification in Ants Across Phylogenetic and Geographic Gradients

open access: yesJournal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim To investigate macroevolutionary and biogeographic patterns of chromosome number variation in ants (Formicidae), and to test whether chromosomal diversity is taxonomically structured, associated with species richness, varies with latitude, and accumulates over evolutionary time. Location Global.

Ponerinae

open access: yes, 2013
Monophyly of Ponerinae and its tribes and genera The monophyly of Ponerinae was strongly supported by analyses of the ALL_DATA matrix (BPP = 1.00, BS = 0.98; Fig. 3), confirming the results of previous molecular phylogenetic studies with more limited sampling of ponerine taxa (e.g., Moreau et al., 2006; Brady et al., 2006) and confirming predictions ...

Bacterial Communities in the Midgut of Ponerine Ants (Hymenoptera: Formicidae: Ponerinae) [PDF]

open access: yesSociobiology, 2016
Symbiotic microorganisms are directly related to the ecological success of host insects, influencing many aspects of their biology. The present study is the first to investigate the microbiota associated with ants of the subfamily Ponerinae and aims to identify the bacterial midgut communities of Dinoponera lucida, Pachycondyla curvinodis, Pachycondyla

Forest Cover and Geographic Distance Shape Ant Assemblages in the Southwestern Brazilian Amazon

open access: yesEcology and Evolution, Volume 15, Issue 11, November 2025.
We investigated how forest cover, precipitation, and spatial distance influence ant species richness and composition in the southwestern Brazilian Amazon. We found that forest cover increases species richness, especially of forest specialists, while spatial distance is the main driver of variation in species composition.

Seasonal cycle of the nest composition in the Ponerine ant Cryptopone sauteri (Hymenoptera: Formicidae)

open access: yesSociobiology, 2017
The annual life history is a basic and important factor in ecological studies on temperate ant species. The biology of Ponerinae species has been studied for many species, but little attention has been paid to their life history.
