The Evolution of Cooperation
Three general models by which cooperation can evolve and be maintained are distinguished: directed reciprocation—cooperation with individuals who give in return; shared genes— cooperation with relatives (e.g., kin selection); and byproduct benefits —cooperation as an incidental consequence of selfish action.
The agricultural pathology of ant fungus gardens.
The increased virulence of pathogens associated with ancient asexual cultivars suggests an evolutionary cost to cultivar clonality, perhaps resulting from slower evolutionary rates of cultivars in the coevolutionary race with their pathogens.
The Evolution of Agriculture in Insects
This work has shown that insect farmers are remarkably similar, suggesting convergent evolution, and that these insect farmers manage, in addition to the primary cultivars, an array of “auxiliary” microbes providing disease suppression...
Ancient Tripartite Coevolution in the Attine Ant-Microbe Symbiosis
Phylogenetic analyses indicate that this long coevolutionary history includes a third symbiont lineage: specialized microfungal parasites of the ants' fungus gardens, intensifying continuous coadaptation between symbionts in a tripartite arms race.
Evolutionary History of the Symbiosis Between Fungus-Growing Ants and Their Fungi
The evolutionary history of the symbiosis between fungus-growing ants (Attini) and their fungi was elucidated by comparing phylogenies of both symbionts, andylogenetic patterns suggest that some primitive attines may have repeatedly acquired lepiotaceous symbions.

The attine symbiosis offers unique experimental opportunities (cultivar switch experiments) to unravel the evolutionary dynamics of conflict and cooperation between ant and fungal partners, and a balanced perspective incorporating both ant andfungal interests emerges.
Inclusive fitness theory and eusociality
It is argued that inclusive fitness theory has been of little value in explained the natural world, and that it has led to negligible progress in explaining the evolution of eusociality, but these arguments are based upon a misunderstanding of evolutionary theory and a misrepresentation of the empirical literature.
The Origin of the Attine Ant-Fungus Mutualism
The attine ant-fungus mutualism probably arose from adventitious interactions with fungi that grew on walls of nests built in leaf litter, or from a system of fungal myrmecochory in which specialized fungi relied on ants for dispersal and in which the ants fortuitously vectored these fungi from parent to offspring nests prior to a true fungicultural stage.
Generalized antifungal activity and 454-screening of Pseudonocardia and Amycolatopsis bacteria in nests of fungus-growing ants
It is concluded that attine-associated pseudonocardiaceous bacteria do not exhibit derived antibiotic properties to specifically suppress Escovopsis, and an alternate conceptual framework is developed to replace the prevailing Pseudonocardia-Escovopsis coevolution model.
Coevolution between Attine Ants and Actinomycete Bacteria: A Reevaluation
Reassessment of the coevolution between actinomycete bacteria and fungus-gardening (attine) ants finds insufficient support for the reverse, modifications of the bacteria resulting from the interaction with attine ants, which remains to be established for the attine ant-actinomyCete mutualism.
