Morphology and Volatilomics of the Pre‐Pharyngeal and Pharyngeal Glands of Paraponera clavata (Hymenoptera: Paraponerinae) and Pachycondyla crassinoda (Hymenoptera: Ponerinae) Workers

Journal of Morphology, Volume 286, Issue 3, March 2025.
This paper describes the morphology and chemical contents of the pre‐pharyngeal and pharyngeal glands in two different ants. The results provide new insights about the morphology and compounds of the exocrine glands in ants. ABSTRACT Ants occur in a remarkable diversity of species, many of which fulfill essential ecological roles and exhibit complex ...

Worker Survival and Egg Production—But Not Transcriptional Activity—Respond to Queen Number in the Highly Polygynous, Invasive Ant Tapinoma magnum

Molecular Ecology, Volume 34, Issue 6, March 2025.
ABSTRACT In social animals, reproductive activity and ageing are influenced by group composition. In monogynous (single‐queen) insect societies, queen presence affects worker fecundity and longevity, but less is known about worker responses to queen number variation in polygynous (multi‐queen) species or how queens age in these systems.

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

EntomoBrasilis, 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.

Variabilidade genética interespecífica em formigas cortadeiras do gênero Acromyrmex que ocorrem no Estado do Rio Grande do Sul Inter-specific genetic variability of leaf cutting ants (Acromyrmex genus) from Rio Grande do Sul State

Ciência Rural, 2007
São poucos os taxonomistas que atuam na identificação de formigas cortadeiras. Os métodos morfométricos utilizados nem sempre permitem uma identificação confiável, em função do acentuado polimorfismo dentro do mesmo formigueiro.

Tree species controls over nitrogen and phosphorus cycling in a wet tropical forest

Ecological Monographs, Volume 95, Issue 1, February 2025.
Abstract Wet tropical forests play an important role in the global carbon (C) cycle, but given current rates of land‐use change, nitrogen (N) and phosphorus (P) limitation could reduce productivity in regenerating forests in this biome. Whereas the strong controls of climate and parent material over forest recovery are well known, the influence of ...
