Table 3. Analyses of densities (0.1 m2) of recruits at several distances from restored (R) or reference (Ref) patches of Phyllospora (a) six or (b) 12 months after the start of the second experiment.

Distance was fixed with 3 levels (inside, edge, 2.5 m), R vs Ref was fixed with 2 levels, Place was random nested in RvRef (1 level for R; 2 [5 mo.] or 3 [12 mo.] levels for Ref), Patch was random nested in Place (1 level for R; 2 levels for Ref). The replicates were the quadrats (n = 5). Transformation of data in (a) failed to make variances homogeneous; data in (b) were ln(X+1) transformed. Cochran's test for homogeneity of variances: a: C = 0.57, P<0.01; b: C = 0.17 ns. Non-significant terms with P>0.25 were pooled.
