Tachykinin expression levels correlate with caste-specific aggression in workers of the leaf-cutting ant Acromyrmex echinatior

open access: yesFrontiers in Ecology and Evolution, 2016
The tachykinins are a family of neuropeptides that influence a range of behavioral phenotypes in both vertebrates and invertebrates; they appear to have a conserved role in the processing of stimuli, and in the control of aggression in a wide range of ...

To vegetable: Seasons that require us

open access: yesCrop Science, Volume 65, Issue 2, March/April 2025.
Abstract Domestication of cereals tracks with the natural life cycle of plants in the Poaceae family, but vegetables represent a different modality and often possess a truncated life cycle. The evolution of vegetable biodiversity required curatorial work each growing season that differed in important ways from curation of grains or perennial crops ...

Peering into the unknown world of amphisbaenians (Squamata, Amphisbaenia): A summary of the life history of Amphisbaena alba

open access: yesActa Zoologica, Volume 105, Issue 4, Page 539-550, October 2024.
Abstract Capturing data on the life of fossorial vertebrates is difficult since access to the subterranean environment is made unfeasible by its density and opacity. Collecting specimens is only possible through excavation work, causing damage or even death to the specimens.

Generation of Nutrients and Detoxification: Possible Roles of Yeasts in Leaf-Cutting Ant Nests

open access: yesInsects, 2012
The possible roles played by yeasts in attine ant nests are mostly unknown. Here we present our investigations on the plant polysaccharide degradation profile of 82 yeasts isolated from fungus gardens of Atta and Acromyrmex species to demonstrate that ...

Viral diversity and co‐evolutionary dynamics across the ant phylogeny

open access: yesMolecular Ecology, Volume 33, Issue 19, October 2024.
Abstract Knowledge of viral biodiversity within insects, particularly within ants, is extremely limited with only a few environmental viruses from invasive ant species identified to date. This study documents and explores the viral communities in ants.

The Foraging Areas of Attine Ants at the Firestone Reserve, Costa Rica [PDF]

open access: yes, 2014
In tropical forest systems, attine ants are the dominant herbivores. They construct large nest structures that include foraging trails that extend to multiple plant sources throughout the forest.

Laccase gene expression as a possible key adaptation for herbivorous niche expansion in the attine fungus-growing ants [PDF]

open access: yes, 2010
Fungus garden enzyme activity is crucial for sustaining societies of attine ants. The evolutionary diversification of this clade has likely been influenced by enzymatic specialization in connection to changes in foraging niche (De Fine Licht, Schiøtt ...

The macroecology of butyrate‐producing bacteria via metagenomic assessment of butyrate production capacity

open access: yesEcology and Evolution, Volume 14, Issue 5, May 2024.
Butyrate‐producing bacteria produce the short‐chain fatty acid butyrate and are vital to ecosystem functionality and human health, but the macroecological influences on their biogeographical distribution remain poorly resolved. Here we developed new normalised butyrate production capacity (BPC) indices derived from global metagenomic (n = 13,078) and ...

Nest Biology and Demography of the Fungus-Growing Ant Cyphomyrmex lectus Forel (Myrmicinae; Attini) at a Disturbed Area Located in Rio Claro, SP, Brazil

open access: yesSociobiology, 2015
Cyphomyrmex ants are a basal group of small fungus-growers (Myrmicinae:Attini), which differ profoundly from their most studied relatives Atta and Acromyrmex.
