Appendix D. ANOVA testing the effects of transect, tidal elevation, and species of propagule on the mean proportion of marked propagules that failed to disperse from a release point.
ANOVA examining the influence of transect (Transect: BM, PL, or MS), tidal elevation (Elevation: high, mid, or low), and species of propagule (Species: Avicennia, Laguncularia, or Rhizophora) on the mean proportions of marked propagules that failed to move out of the 25-cm radius circle (centered on a release point) into which they were originally deposited. Data for each species are for the full periods of monitoring: two-week values for Laguncularia and four-week values for Avicennia and Rhizophora. Analysis is mixed-model with transect treated as a random factor, and elevation and species as fixed factors. Proportions were arcsine transformed prior to analysis to homogenize variances (C = 0.142, P > 0.05).
