Symbiotic Nitrogen Fixation in the Fungus Gardens of Leaf-Cutter Ants
Science, 2009Gardening for Ants and Termites Among the social insects, ants and termites are the most diverse and ecologically dominant. Termites are known to engage in a mutualism with nitrogen-fixing bacteria, and Pinto-Tomás et al. (p.

Foraging by Bucket-Brigade in Leaf-Cutter Ants
Biotropica, 1980Atta cephalotes foragers transfer leaf fragments to "carrier" ants at junctions of new branch trails and the established trail. A more pronounced specialization into "harvesters" and "carriers" is exhibited by A. sexdens rubropilosa in which smaller ants harvesting in the tops of tall trees drop material to the ground where larger workers collect it ...

Undertaking specialization in the desert leaf-cutter ant Acromyrmex versicolor
Animal Behaviour, 1999We investigated undertaking behaviour in the desert leaf-cutter ant to determine whether colonies show undertaking specialization, how task specialization is regulated and the consequences of specialization on colony performance. Task specialization has been hypothesized to be a result of internal physiological or genetic factors that govern worker ...

Energetics of trail clearing in the leaf-cutter ant Atta
Behavioral Ecology and Sociobiology, 2016Few ant species construct cleared trails. Among those that do, leaf-cutting Atta ants build the most prominent networks, with single colonies clearing debris and obstructions from hundreds of meters of trails annually. Workers on cleared paths move at higher speed than they do over uncleared litter, and one measurement of the time and energetic costs ...

Dispersal of Attaphila fungicola, a symbiotic cockroach of leaf-cutter ants
2021Animal dispersal between habitats is difficult to observe from beginning to end. This is especially true of tiny, cryptic animals resistant to tracking methods. Attaphila fungicola is a miniature cockroach that lives in the deep, subterranean nests of leaf-cutter ants, a symbiont of the leaf-cutters and their mutualist fungal gardens.

Disease defence through generations: leaf‐cutter ants and their symbiotic bacteria
Molecular Ecology, 2013Microbial ecology of animals is taking on significance in the modern dialogue for the biology of species. Similar to a nuclear genome, the entire bacterial assemblage maintains an ancestral signal of the host's evolution leading to cophylogeny between the host and the microbes they harbour (Brucker & Bordenstein 2012b).

Dispersal of Attaphila fungicola, a symbiotic cockroach of leaf-cutter ants
Insectes Sociaux, 2017The myrmecophile cockroach Attaphila fungicola lives in the nests of leaf-cutter ants (Atta texana and A. cephalotes) and uses the female winged reproductives (i.e., female alates) of its host as vectors for the first phase of its dispersal. It is unknown whether A. fungicola remain with vectoring A. texana females after mating flights and throughout A.

Leaf cutter ants: a possible missing source of biogenic halocarbons
Environmental Chemistry, 2008Environmental context. With large reductions in anthropogenic emissions of many ozone-depleting gases in response to the Montreal Protocol, gases with biogenic sources have become relatively more important in recent years. The global budgets of the biogenic halocarbons are unbalanced with known sinks outweighing sources, suggesting that additional ...

Foraging activity of leaf‐cutter ants is affected by barometric pressure
Ethology, 2019AbstractAmong all activities displayed by ant colonies, searching for food is essential for all individuals survival. However, many external activities are hazardous or restrictive for the entire society. Even though leaf‐cutter ants are highly successful insects, they are subject to extreme aspects of foraging, as raindrops and wind.
