Jennifer A. Rudgers, Tom E. X. Miller, Shaun M. Ziegler, and Kelly D. Craven. 2012. There are many ways to be a mutualist: Endophytic fungus reduces plant survival but increases population growth. Ecology 93:565–574.

Appendix B (TABLE B1). Results from statistical analyses of the responses of Cinna arundinacea to the endophyte treatment (endophyte-free (E-) or endophyte-symbiotic (E+)) in experimental field plots (cohorts) planted during 2007 or 2008 and surveyed in years 2008 and 2009.
