Chromosome Mapping of Ribosomal DNA Clusters in Four Leaf-cutting Ant Species of the Genus Acromyrmex, with Description of a Triploid Individual in A. laticeps

Sociobiology
The increase of cytogenetic data in the leaf-cutting genus Acromyrmex has shown interesting contributions to the evolutionary and taxonomic approaches, including the creation of a new genus and the description of chromosomal patterns allowing ...

The functional role of ants in no‐till cropping systems

Pest Management Science, EarlyView.
Ants provide valuable ecosystem services in tropical agriculture, but their roles in temperate row crops remain poorly understood. Conservation practices such as no‐till farming and cover cropping support ant communities that contribute to pest suppression, weed seed removal, and soil quality, which can increase crop productivity.

The continuing significance of chiral agrochemicals

Pest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Just Transition in Europe: A Regional Analysis of Environmental Inequality

Sustainable Development, EarlyView.
ABSTRACT The European Green Deal and the just‐transition agenda promise that no person and no place will be left behind, yet the regional distribution of multi‐impact, emission‐based environmental burdens remains insufficiently understood across Europe.

Reproduction of leaf-cutting ant workers: breaking the queen monopoly [PDF]

Brazilian Journal of Biology
The complex colony organization with labor division, age polyethism and polymorphism, specialized tasks among younger and older workers, subdivision into subcastes, and the cultivation of symbiotic fungus as the primary food source, distinguishes leaf ...

Impact of Environmental Microparticles on Insect Olfaction

Environmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.

Fuzzy modeling of reoccupation of a leaf-cutting ants’ trail

TEMA (São Carlos), 2015
In this paper we model the reoccupation of a trail by leaf-cutting ants.<br />The mathematical modeling consists in studying the leaf-cutting ants’ displacement<br />towards an attraction area and their return to the nest. To carry out this research,<br />we utilized the diffusion-advection equation, where the dispersion and velocity ...

Nest Digging by Leaf-Cutting Ants: Effect of Group Size and Functional Structures

Psyche: A Journal of Entomology, 2012
Leaf-cutting ant workers dig underground chambers, for housing their symbiotic fungus, interconnected by a vast quantity of tunnels whose function is to permit the entrance of food (leaves), gaseous exchanges, and movement of workers, offspring, and the ...

Resilience in the heights: Elevational filtering preserves taxonomic and functional beta diversity over time against biotic homogenization

Functional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Environmental heterogeneity generates taxonomic and functional beta diversity, but a key question regards whether heterogeneity can maintain functional diversity when global change causes range shifts, potentially causing biotic homogenization by favouring species ...
