Abstract

The ability of organisms to form long term intimate and diverse relationships with each other (symbiosis) is now recognized as a common ecological phenomenon. Symbiosis, as a general term, does not imply detriment or benefit, but rather that the outcome (net effect) of species interaction exists within a symbiotic continuum or “species interaction grid” that includes agonism (predation and disease) and mutualism (benefits for both species).1,2 The continuum also includes pleotropic symbiosis, where net effects of species interaction vary spatially or temporally in relative agonism or mutualism.3 Grasses systematically infected with specific clavicipitaceous fungi are examples of species interactions that span the symbiotic continuum, profoundly affecting the ecological fitness of the hosts.4–8
