Are Plant Species’ Richness and Diversity Influenced by Fragmentation at a Microscale?

Table 5

Difference in mean values of the patch’s variables used as input data for the linear regression analysis. The data is analysed between forest types. Information on geographic location of the patches is not included in the table. PCA 1: area; PCA 2: shape; PCA 3: proximity; PCA 4: contiguity.
