Appendix C. ANOVAs testing the effects of transect, tidal elevation, species of propagule, and release point on the mean distance moved by marked and released propagules.
ANOVA examining the influence of transect (Transect: BM, PL, or MS), tidal elevation (Elevation: high, mid, or low), species of propagule (Species: Avicennia, Laguncularia, or Rhizophora), and release point (Release point: each species released at three points per elevation on a transect) on the mean distance moved by marked and released propagules. Analysis I compared movements of the three species’ propagules over two-week periods, while Analysis II compared movement over the entire periods of monitoring: four weeks for Avicennia and Rhizophora vs. two weeks for Laguncularia. See text for details. Analyses were mixed-model with Transect and Release point treated as random factors, and Elevation and Species as fixed. Release point was nested within Transect, Elevation, and Species. Distances were log10 (X + 1) transformed prior to analysis.
