Appendix C. MANOVA/ANOVA tables showing the effects of Cuscuta salina removal on fitness indicators of the dominant host Plantago maritima and the rare Cordylanthus maritimus ssp. palustris.
TABLE B1. Results of MANOVA and "protected" univariate F test results on the effect of Cuscuta removal on log-transformed fitness indicators of the dominant host Plantago maritima following 16 weeks of parasitism. Host fitness metrics include rosette growth (increase in rosette diameter), total dry biomass, increase in number of inflorescences, and total aggregated inflorescence spike length per plant.

TABLE B2. Results of MANOVA and "protected" univariate F test results on the effect of Cuscuta removal on log-transformed fitness indicators of Cordylanthus maritimus ssp. palustris. Hemiparasite fitness indicators measured at reproductive maturity include height, number of branches, flower production, seed capsules set, seed capsules matured, and total plant biomass.
