Alpine plant community diversity in species–area relations at fine scale

Figures & data

Table 1. GLM results for the dependent species–area slope with the independent site variables. The contribution is the percentage that each source in the analysis of variance table contributes to the total sequential sums of squares

	Contribution (%)	p
Stability	14.60	.000
Talus	9.37	.001
Outcrops	3.26	.045
Total R^2	27.22

Table 2. Commonality analysis, which partitions the R² in simple and multiple regressions, for the three independent variables that were significant in the GLM

	Variance partitioned (%)
Stability	11.94
Talus	9.37
Outcrops	3.25
Stability + Talus	2.72
Stability + Outcrops	2.01
Talus + Outcrops	−0.58
All three	−2.07

Figure 1. The species–area slope regressed on the plot gamma diversity; the relationship is significant at p < .05
