Condensed tannins, attine ants, and the performance of a symbiotic fungus

Journal of Chemical Ecology, 1991
Field experiments indicate that the foliar concentration of condensed tannin affects the selection of leaf material ofInga oerstediana Benth., a tropical legume tree, by leaf cutter ants. In one study an increase in tannin concentration was correlated with a decrease in the acceptability of leaves to leaf-cutter ants, except at low tannin ...

The Origin of the Attine Ant-Fungus Mutualism

The Quarterly Review of Biology, 2001
Cultivation of fungus for food originated about 45-65 million years ago in the ancestor of fungus-growing ants (Formicidae, tribe Attini), representing an evolutionary transition from the life of a hunter-gatherer of arthropod prey, nectar, and other plant juices, to the life of a farmer subsisting on cultivated fungi.

Ancient Tripartite Coevolution in the Attine Ant-Microbe Symbiosis

Science, 2003
The symbiosis between fungus-growing ants and the fungi they cultivate for food has been shaped by 50 million years of coevolution. Phylogenetic analyses indicate that this long coevolutionary history includes a third symbiont lineage: specialized microfungal parasites of the ants' fungus gardens.

Chemical investigations of the Dufour gland contents of Attine ants

Insect Biochemistry, 1981
Abstract The Dufour glands of workers of the two subspecies Atta sexdens and Atta sexdens rubropilosa are completely filled with linear alkanes and alkenes in the C15 to C23 chain length range in microgram amounts. There are quantitative differences in the hydrocarbon composition between workers of the two subspecies. The major glandular component of

Factors influencing the growth of Attamyces bromatificus, a symbiont of attine ants

Transactions of the British Mycological Society, 1986
Investigations of conditions for optimum growth of the attine symbiont Attamyces bromatificus revealed that it was inhibited by light and grew best at temperatures between 20 and 25°C, while temperatures above 30° were lethal. Mean gongylidia size remained small in cultures at 15°.

Agro-predation: usurpation of attine fungus gardens by Megalomyrmex ants

Naturwissenschaften, 2000
A new ant species of Megalomyrmex conducts mass raids to usurp gardens of the fungus-growing ant Cyphomyrmex longiscapus, then lives in the gardens and consumes the cultivated fungus. Unlike attine ants, however, Megalomyrmex sp. does not forage for substrate to manure the gardens; therefore, when gardens become depleted, Megalomyrmex sp.

A comprehensive biogeographical overview of the evolutionary history of the higher attine ants

Biological Journal of the Linnean Society
We investigated the biogeographical history of the higher attines, a group of fungus-farming ants that are widespread across American landscapes. We aimed to determine the tempo and direction of dispersal of their ancestors among the major biomes of ...

The biochemical basis of the fungus-attine ant symbiosis.

Science (New York, N.Y.), 1970
The natural history of the fungus-growing ants provides a spectacular example of a symbiotic association of two very different types of organisms. An anthropomorphic description is difficult to resist. The ants are efficient and industrious farmers.
