Evidence for toxin-encoding coinfections driving intransitive dynamics between allelopathic phenotypes in natural yeast populations.

Abstract excerpt

Competitive intransitivity, or non-hierarchical competitive interactions, such as those exemplified by the rock-paper-scissors game where no single competitor wins outright, has been proposed as a key mechanism for maintaining biodiversity; however, empirical evidence supporting the importance of intransitivity remains limited. Natural populations of Saccharomyces cerevisiae often include strains harboring...
