Shifts in Chromosome Evolution Rates Shape the Karyotype Patterns of Leafcutting Ants. [PDF]

Ecol Evol
Modern phylogenetic methods were used to explore how chromosome number and other karyotypic traits vary across species. The focus was on testing whether karyotypic traits follow a Brownian motion model (indicating neutral changes) or are influenced by phylogenetic constraints.This research elucidates the mechanisms underlying chromosomal evolution and ...

Vertical Stratification Increases the Capacity of Morphological Traits to Predict Trophic Position in Neotropical Ants. [PDF]

Ecol Evol
We use data from 73 Neotropical ant species to examine the strength of associations between nine morphological traits and trophic position. No individual morphological trait explained variation in the trophic position of arboreal species, whereas three traits individually correlated with the trophic position of ground species, but only weakly so ...

Ant Diversity and Stratification in an Amazonian Rainforest. [PDF]

Ecol Evol
We examined the three strata of an Amazonian rainforest (e.g., the ground and leaf litter, understory and canopy) using only two sampling techniques and analyzed their functional traits. We identified 494 ant species from 10 subfamilies and 77 genera over ≈3.0 ha, showing that they are species rich and abundant, particularly at ground level.

Large deformation diffeomorphic mapping of 3D shape variation reveals two distinct mandible and head capsule morphs in Atta vollenweideri leaf-cutter worker ants. [PDF]

Ecol Evol
Atta vollenweideri leaf‐cutter ant workers vary continously in size across more than two orders of magnitude in body mass. We investigated whether size‐variation correlates with shape variation by analysing the 3D morphology of mandibles and head capsules.

Leaf-cutting ant (Atta laevigata Smith) in an African mahogany plantation in Minas Gerais state, Brazil

EntomoBrasilis, 2021
Khaya grandifoliola C. DC. (Meliaceae), known as African mahogany, is used in the establishment of commercial plantations for high-value timber production. This work aims to report the first occurrence of the genus Atta in a commercial plantation of this

New behavior report by Canthon virens (Mannerheim, 1829) (Coleoptera: Scarabaeidae: Scarabaeinae) in Southeastern Brazil

Entomological Communications, 2022
Canthon virens (Mannerheim, 1829) (Coleoptera: Scarabaeidae: Scarabaeinae) prey on leaf-cutting ants, using their body for provisioning larvae, as part of the reproductive behavior. Here, we report an observation of a new behavior of C.

Foraging by predatory ants: A review. [PDF]

Insect Sci
This review focuses on ecological and behavioral characteristics of foraging in ants showing the wide diversity of cases. Most ants can feed on sugary substances, but some ground‐nesting species are strict predators. Except army ants during the nomadic phase, they are central‐place foragers that can recruit nestmates when necessary. They prey mostly on

Phylogenomic reconstruction reveals new insights into the evolution and biogeography of Atta leaf‐cutting ants (Hymenoptera: Formicidae)

Systematic Entomology, Volume 47, Issue 1, Page 13-35, January 2022., 2022
We employ phylogenomic markers (UCEs) to reconstruct the most extensively sampled phylogeny to date for the ecologically dominant leaf‐cutting ant genus Atta, the major herbivore of the New World tropics. The ancestor of Atta arose 8.5 Ma in the North/Central America + NW South America range, and its descendant species rapidly radiated into Neotropical
