Appendix C (TABLE C1). Parameters and empirical point estimates for Cinna arundinacea  Neotyphodium schardlii population dynamics. Parameters f and s represent the fecundity and survival, respectively, of symbiotic (E+) and symbiontfree (E) hosts. F and S are the ratios of symbiotic to symbiontfree values. r represents the host life history context and is defines as f / s. Empirical estimates for f are based on seed production multiplied by recruitment probability.
