Appendix G. Results of repeated-measures MANOVA tests for growth rate, stage of maturity, gonadosomatic index, and carotenoids in the field transplant experiment.

TABLE G1. Results of repeated-measures MANOVA tests for growth rate, stage of maturity, GSI, and carotenoids in the field transplant experiment. Growth rate data were arcsin-square root transformed, and the other response variables were ln-transformed to improve normality. Comparisons were performed between edges for in situ mussels, between edges and treatments for the first two time points, and within the high edge for all treatments and time points. Values for P < 0.05 are in boldface.
