Appendix B

Figure B.1

Non-metric multidimensional scaling ordination plot displaying mean (± 1 SD) compositional dissimilarity among sampling points with increasing distance from the remnant forest edge for seed rain (A) and seedling communities (B), using a log-base 10 Modified-Gower dissimilarity metric. The grey-scale gradient denotes the increasing distance from the forest edge from darkest (-5 m) to lightest (30 m). Stress values of 0.239 (B) and 0.199 (B) indicate that the best 2-dimensional configuration of the NMDS closely resembled the dissimilarity between sampling points.




Figure B.2

Generalised additive mixed models demonstrating the relationships between distance from the forest edge and mean seed diameter for seed-rain (a) and seedling communities (b). Black smoothed lines are fitted values and grey lines denote the bounds of the 95% confidence interval. Negative and positive x-axis values denote forest and matrix, respectively, with 0 to denote the edge.
