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 ...

Evaluating endophyte‐rich leaves and leaf functional traits for protection of tropical trees against natural enemies

Functional Ecology, Volume 39, Issue 2, Page 371-389, February 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plants use physical barriers and chemical compounds to defend themselves against natural enemies. For instance, tough leaves are considered to be better defended than soft leaves, part of a spectrum of defences defined by functional traits such as leaf chemistry ...

Mind the gap! Integrating taxonomic approaches to assess ant diversity at the southern extreme of the Atlantic Forest [PDF]

, 2017
Understanding patterns of species diversity rely on accurate taxonomy which can only be achieved by long-term natural history research and the use of complementary information to establish species boundaries among cryptic taxa.

Bimodal alarm signals modulate responses to monomodal alarm signals in Camponotus modoc carpenter ants

Insect Science, Volume 32, Issue 1, Page 343-355, February 2025.
Distressed Camponotus modoc carpenter ants emit alarm pheromone and produce vibratory alarm signals. Presented as a monomodal signal, the pheromone attracts nestmates, whereas vibratory signals cause nestmates to “freeze” or to run fast. Sensing a bimodal signal complex, nestmates are less attracted to pheromone but stay “frozen” longer which seems ...

Forager size of the leaf-cutting ant Atta sexdens (Hymenoptera: Formicidae) in a mature eucalyptus forest in Brazil

Revista de Biología Tropical, 2000
We determined the size characteristics of foragers of the leaf-cutting ant Atta sexdens in a mature eucalyptus forest in Campos dos Goytacazes, Rio de Janeiro State, Brazil, at daytime (7: 30 to 10: 00 hr) and nighttime (19: 00 to 23: 00 hr).

Microbial Communities in Different Tissues of Atta sexdens rubropilosa Leaf-cutting Ants [PDF]

Current Microbiology, 2017
Bacterial endosymbionts are common in all insects, and symbiosis has played an integral role in ant evolution. Atta sexdens rubropilosa leaf-cutting ants cultivate their symbiotic fungus using fresh leaves. They need to defend themselves and their brood against diseases, but they also need to defend their obligate fungus gardens, their primary food ...
