Fig. 6. Influence of habitat classes and environmental measures on the composition of the 93 species quantified in the 252 pixel-based vegetation quadrats. Graph A is a canonical correspondence analysis (CCA) ordination plot showing the mean (± SE) of sample scores for each habitat class (19 ≤ n ≤ 21 pixel vegetation quadrats per habitat class). Graph B is a CCA ordination bi-plot showing the scores for species and environmental variables; these variables are defined in Fig. 3. The first and second axes explained 7.3 and 5.9% of the variation, respectively. Genus and species codes are defined in Appendix 2. Species are displayed according to their fit and weight (Šmilauer 1992). Habitats are defined in Table 1 and represented by numbers 1 through13. Species listed at the bottom left of Graph B correspond to the unlabeled point in the center of the bi-plot.
