Leaf-cutting ants (LCA) are considered one of the main herbivores and one of the most destructive pest insects of the Neotropics. Northeastern Argentina harbors the greatest species richness of these ants and in turn comprises the highest surface with forest plantations. Our aim was to establish which species of leaf-cutting ants are most commonly...

1. Understanding the spatial distribution of species sheds light on the biogeographical history, offers clues to the drivers of biodiversity and helps guide conservation strategies. In southern South America, Andean, Chaco and Atlantic forests drastically decreased their coverage in the last decades mainly by changes in land use. 2. Ants represent...
Article
Chromosomal inversions are known to play roles in adaptation and differentiation in many species. They involve clusters of correlated genes (i.e loci in linkage disequilibrium, LD) possibly associated with environmental variables. The grasshopper “species complex” Trimerotropis pallidipennis comprises several genetic lineages distributed from North...
Article
Full-text available
Ants, an ecologically successful and numerically dominant group of animals, play key ecological roles as soil engineers, predators, nutrient recyclers, and regulators of plant growth and reproduction in most terrestrial ecosystems. Further, ants are widely used as bioindicators of the ecological impact of land use. We gathered information of ant sp...
Article
Leafcutting ants are considered the most important herbivores in terrestrial environments throughout the Neotropics. Amoimyrmex is the sister clade of the remaining leafcutter ants from the genera Atta and Acromyrmex . Amoimyrmex striatus was the only species cytogenetically studied within the genus and shares the same chromosomal number with Atta...
Preprint
Chromosomal inversions play a role in the adaptation and diversification of different systems, mainly due to supergenes resulting from recombination suppression. Supergenes are “clusters” of genes in linkage disequilibrium (LD) whose frequencies may be associated with environmental variables. The grasshopper “species complex” Trimerotropis pallidip...

Hedychium coronarium (Zingiberales: Zingiberaceae), native to the Himalayas and southern China, has become an environmental weed in many countries around the world. Reported in several provinces of Argentina, H. coronarium constitutes a serious environmental problem especially in the wetlands of natural areas of Misiones Province, such as the Iguaz...
Article
1 The most commonly used method to control insect pests, such as leaf-cutting ants (LCA) in forest plantations, is the application of chemical insecticides, but their use was forbidden in plantations certified by the Forest Stewardship Council because of their negative effect on the environment. 2 A 5-year derogation of their prohibition was obtain...

The southern black ant, Acromyrmex lobicornis, is a species of leaf-cutting ant with a wide distribution in southern South America. Mostly distributed in Argentina, it's range extends from southern Brazil, Bolivia and Paraguay to the province of Chubut in Patagonia, and it is apparently in the process of a southwestern expansion into Chile. It's ad...

The genus Mycetarotes is a fungus-growing ant (Formicidae: Myrmicinae: Attini) mostly recorded south of the Amazon: in southeastern Brazil, Paraguay, and northern Argentina. Here we report the first record of this genus in Colombia: M. parallelus (Emery, 1906). We collected the specimen using pitfall taps in oil palm plantations. The discovery of t...

The first step to estimate the post-mortem interval is the identification of species of insects found on carcasses. Blowflies are an important portion of the insect species in forensic researches. Here, we evaluated the succession of blowfly species associated with pig carcasses (Sus scrofa) on pastures of Cogua (Cundinamarca). The blowflies were c...

Oil palm agriculture is rapidly expanding in the Neotropics, at the expense of a range of natural and seminatural habitats. A key question is how this expansion should be managed to reduce negative impacts on biodiversity. Focusing on the Llanos of Colombia, a mixed grassland–forest system identified as a priority zone for future oil palm developme...

Project
Leaf-cutting ants, comprising the genera Atta and Acromyrmex, are part of the larger group of fungus-growing ants, a clade characterized by the habit of feeding on basidiomycete fungi cultivated on appropriate substrates, such as leaves and flowers, especially collected and prepared for the fungi. By this habit and their ability to harvest large amounts of vegetation, the leaf cutting ants are considered one of the main herbivores in the Neotropic. However, most species act as key components of ecosystems due to their role in nutrient cycling and in the regulation of primary production. They are distributed from the southern United States to the province of Chubut in Argentina. The greatest richness of leaf cutting ants is found in southern Brazil and northern Argentina, where the distribution of some species of Acromyrmex seems to indicate a progressive adaptation from humid zones to more arid environments of the South of the continent. The aim of this project is to perform phylogeographic and phylogenetic studies of the most relevant leaf cutting ants in southern South America, in order to determine their patterns of dispersal, centers of genetic diversity and historical processes of dispersion, which could have led to their current distribution patterns.
