Appendix B. Study sites, hosts, and incidence of endophyte infection among 2-mm2 segments of photosynthetic tissues for 34 host species–site combinations (summarized in Fig. 1A).
Data reflect the proportion of tissue segments from which endophytes were isolated in culture. Surveys included three to nine individuals per host species per site, and three to nine leaves or photosynthetic stems per individual. A total of 120–720 tissue segments was examined per species in each site. Site abbreviations are as follows: BCI, Barro Colorado Island, Panama; TAZ, Tucson, AZ, USA; SCA, Santa Catalina Mountains, near Tucson, AZ, USA; DNC, Duke Forest, North Carolina, USA; MAQ, Mingan Archipelago, Québec, Canada; MRQ, Moisie River, Moisie, Québec, Canada; SHQ, Schefferville, Québec, Canada; IQN, Iqaluit, Nunavut, Canada. Data for TAZ and SCA were combined for analysis. Data for Platycladus orientalis and Cupressus arizonica are used with permission from M. Hoffman (MH and AEA, unpublished data).
