jvs1351-sup-0001-TableS1.docWord document79KTable S1. Path model test results for temperate, subtropical and tropical forests for the five models tested from Fig. S1. Bold = most valid model. Variant of Model III represents the model with the greatest P-value from all permutations of removing insignificant arrows from model III.
jvs1351-sup-0002-TableS2.docWord document49KTable S2. Path model test results for subtropical and tropical forests for the five models tested from Fig. S1. Bold = most valid model. Model II shows P = 0.99; however its low df of 2 (i.e. one test) makes it a less reliable choice compared to model I that shows = 0.47 with 4 df. Variant of Model V represents the model with the greatest P-value from all permutations of removing insignificant arrows from model V.
jvs1351-sup-0003-TableS3.docWord document90KTable S3. Summary of fits for power, Michaelis-Menten and negative exponential functions to species-sampling relationships (SSRs) (bold = best fit of each function). Subtropical shrubland I and II from Table 1 only have one species per site, making SSR estimates impossible for these two sites. Functions from Tjørve (2003); Dengler (2009).
jvs1351-sup-0004-FigureS1.tifimage/tif213KFigure S1. The five path models tested in this study. Black arrows highlight additional paths to model I; black circles represent arrows removed from model I.
jvs1351-sup-0005-FigureS2.tifimage/tif99KFigure S2. Relationship between z and richness for temperate, subtropical and tropical sites. z is calculated from richness, and was therefore left out of the path models due to issues determining causality.
jvs1351-sup-0006-FigureS3.tifimage/tif282KFigure S3. Species richness (S) and Shannon diversity (H′) against basal area for the temperate, subtropical and tropical forest at the quadrat scale of 100m2. Temperate sites show a leveling off of S and H′ in least disturbed and undisturbed forest sites, whereas subtropical and tropical sites do not (consistent with Fig. 5).
jvs1351-sup-0007-FigureS4.tifimage/tif89KFigure S4. % zoochory, z and richness against distance from forest for the temperate forest. No relationship was observed for any of the plots.
