Many plants support symbiotic microbes, such as endophytic fungi, that can alter interactions with herbivores. Most endophyte research has focused on agronomically important species, with less known about the ecological roles of native endophytes in native plants. In particular, whether genetic variation among endophyte symbionts affects herbivores of plant hosts remains unresolved for most nat...

28 fledged per nest in the native habitat, but only 1.0 per nest in the wheatgrass, Lloyd and Martin reported in 2005 (Condor 107:363–374). These significantly different success rates resulted primarily from greater nest predation in the wheatgrass. The odds of a nest surviving a given day were 17 percent higher in the native-prairie patches than in the wheatgrass plots. Nestlings in the native...
