Foraging of Psilocybe basidiocarps by the leaf-cutting ant Acromyrmex lobicornis in Santa Fé, Argentina [PDF]
SpringerPlus, 2013 It is generally accepted that material collected by leaf-cutting ants of the genus Acromyrmex consists solely of plant matter, which is used in the nest as substrate for a symbiotic fungus providing nutrition to the ants. There is only one previous report of any leaf-cutting ant foraging directly on fungal basidiocarps.Basidiocarps of Psilocybe ...

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

The effect of increase in the temperature on the foraging of Acromyrmex lobicornis (Hymenoptera: Formicidae) [PDF]
Zoological Studies, 2014 The leaf-cutting ants appear to be a suitable group for studying the effect of global warming on ectothermic animals. These ants of the Atta and Acromyrmex genera are considered to be the main herbivores in the Neotropics. They have patterns of harvesting associated with ranges of temperature.

Exposure to creosote bush phenolic resin causes avoidance in the leaf-cutting ant Acromyrmex lobicornis (Formicidae: Attini) [PDF]
Revista Chilena De Historia Natural, 2012 We focused our study on the effects of Larrea cuneifolia phenolic resin on leaf-cutting ants from two populations (Sierra de las Quijadas National Park and San Roque) of Acromyrmex lobicornis in San Luis, Argentina. We conducted two bioassays of food choice (fi eld and laboratory) to compare the effects of phenolic resin on ant workers from these two ...
