Fig. 2. DCA ordination biplot (1st and 2nd axis) with projected species (options Display species with some labels will draw names of selected species so as these labels doesn't overlay) and Ellenberg indicator values (option Use Ellenberg indicator values as vectors). Abbreviations: TEMP - temperature, REACT - soil reaction, LIGHT - light, CONT - continentality, NUTR - nutrients and MOIST - moisture.
Fig. 4. DCA ordination biplot (2nd and 3rd axis) with projected sites (circles), factor from Short header (pH) and Ellenberg indicator values (EIV) - significance of each EIV is assessed using permutation test (1000 permutations) and significant values (p<0.01) are drawn dark blue, non-significant grey (options: DCA, Display sites as points, Use Data from Short Headers as Vectors, Factor name is 'pH', Use Ellenberg Indicator Values as vectors, Axes shown Second & Third)
Fig. 5. NMDS analysis biplot (1st and 2nd dimension) with projected sites (circles) and factor from Short headers (pH) as a surface (options NMDS, Display sites as points, Use Data from Short Headers as Surface).
