TY - GEN N1 - 24 cm N2 - Comparative analysis was performed using the scales of ecological indicator values for plant species proposed by: (1) Ellenberg for the flora of Germany, (2) Landolt for the flora of Switzerland and (3) Zarzycki for the flora of Poland, in relation to six environmental features concerned with climate (i.e. light intensity [L], temperature [T] continentality [K]) and soil (moisture [F], acidity [R] and nitrogen content [N]). Species characteristic for deciduous forest of class Querco-Fagetea were used as the ”tool” in the comparison. Numbers of species differ – from 83 to 105 depending on environmental feature. It was assumed that pairs of ecological scales are similar if the percentage share of species is above 50% in corresponding degrees of scales. The main aim of the analysis is to determine if compared scales originating from different parts of Central Europe are similar (or distinct) in the ecological diagnosis (climatic and soil) diagnosis as expressed by the three indicator values (corresponding to the three scales) for each feature of the geographical environment. Results were interpreted in respect of two opposing hypotheses. The first of these assumes that the scales compared are similar, with the particular degrees conforming to the same ranges of actual measurements, while differences concern the assessment of the requirements of species as indicators of environmental conditions. The second, alternative hypothesis assumes that the scales are different (most often shifted by one degree), while the ecological requirements of the species are similar. The analysis of histograms of frequency of the particular species categories shows that support for the first of the two hypotheses is provided by the pairs of scales for: (1) light intensity [L] of Ellenberg and Zarzycki; (2) temperature [T] of Ellenberg and Landolt; (3) degree of continentality [K] of Landolt and Zarzycki; (4) moisture of the soil [F] of Ellenberg and Zarzycki; (5) acidity of the soil [R] of Ellenberg and Zarzycki; and (6) nitrogen content in the soil [N] of Ellenberg and Landolt. as regards the second hypothesis, the distribution of frequencies for species categories in the histograms allows for the explanation of differences (shifts) within the following pairs of scales compared: (1) temperature [T] of Ellenberg and Zarzycki; (2) climate continentality [K] of Ellenberg and Zarzycki, (3) soil acidity [R] of Ellenberg and Landolt, and of Landolt and Zarzycki; and (4) nitrogen content in the soil [N] of Landolt and Zarzycki. It is worth noting that similar results and conclusions were achieved when the same ecological scales of indicator values were compared, albeit on the basis of species from meadows in class Molinio-Arrhenathereta (Roo-Zielinska, 2004). This means that a total of c. 200 species (of meadow and deciduous forest) were evaluated. However it is only 10% of K Zarzycki list of Polish flora (Zarzycki et al., 2002), but ecological spectra and tolerance of both groups (with large number of species) are very different. The obtained results suggest a need to continue with such comparative analyses of European ecological scales for groups of characteristic species belonging to different phytosociological units, and to find proper ecological indicator values for the Polish flora and plant communities.

Characteristic species of heaths and poor grasslands from class Nardo-Callunetea were used asthe” tool” in the above comparison. Numbers of species involved ranged from 28 to 53, depending on the environmental features and compared scales involved. The assumption was that pairs of ecological scales were similar where the percentage share of species is above 50% in corresponding numbers along the scales. The main aim of the analysis was in turn to determine if compared scales originating from different parts of central Europe were similar (or distinct) in their ecological (climatic and edaphic) diagnoses, as expressed in terms of three indicator values (corresponding to three scales) for each relevant feature of the geographical environment. Results obtained were interpreted by reference to two opposing hypotheses. The first assumes that the scales compared are similar, with particular numbers along the scales conforming to the same ranges of actual measurements, while differences concern the assessment of the requirements of the species as indicators of environmental conditions. The second, alternative hypothesis assumes that the scales are different (most often shifted by one degree), while the ecological requirements of the species are similar. Analysis of histograms for frequencies of particular species categories shows that examples sustaining the first of the two hypotheses are provided by the pairs of scales of: (1) temperature [T] of Ellenberg and Landolt; (2) continentality (K) of Landolt and Zarzycki, (3) soil moisture [F] of Ellenberg and Zarzycki; (4) nitrogen content in the soil [N] of Ellenberg and Landolt. In relation to the second hypothesis, the distribution of frequencies of the species categories in the histograms allows for the explanation of differences (in terms of shifts) within the following pairs of scales compared: (1) temperature [T] of Landolt and Zarzycki; (2) soil moisture [F] of Landolt and Zarzycki; (3) soil moisture of Landolt and Zarzycki; (4) soil acidity of Landolt and Zarzycki; (5) nitrogen content in the soil [N] of Ellenberg and Zarzycki. It is worth noting that a similar analysis was achieved when the same ecological scales of indicator values were compared by reference to meadow species from class Molinio-Arrhenathereta (Roo-Zielinska, 2004), deciduous forest of class Querco-Fagetea (Roo-Zielińska, 2009), xerothermic grasslands of class Festuco-Brometea (Roo-Zielińska, 2012) and sandy xeric grasslands of class Koelerio glaucae-Corynephoretea canescentis class (Roo-Zielińska, 2015). This means that a total of some 460 species (of meadows, deciduous forests, xerothermic and sandy xeric grasslands, and heaths and poor grasslands) have now been evaluated. While this still only represents some 23% of K Zarzycki’s list of the Polish flora (Zarzycki et al., 2002), very different ecological spectra and tolerance in the five groups have not precluded the highlighting of certain regularities applying to the plant communities already studied. The results obtained point to the need for comparative analysis of European ecological scales for groups of characteristic species belonging to different phytosociological units/associations to be continued with, with ecological indicator values appropriate to Poland’s flora and plant communities then being found.

Species characteristic of sandy xeric grasslands from Koelerio glaucaeCorynephoretea canescentis class were used as a ”tool” in the comparison. Numbers of species differ – from 55 to 62 - depending on environmental features and the compared scales. However, it was assumed that pairs of ecological scales were similar if the percentage share of species was above 50% in corresponding points on scales. The main aim of the analysis was to assess whether compared scales originating from different parts of Central Europe are similar (or different) in their ecological diagnosis as regards climatic and edaphic conditions, where each feature of the geographical environment is expressed in relation to three indicator values deriving from the three scales. The interpretation of results was based around two opposing hypotheses: that the scales compared are similar, with particular points along them conforming to the same ranges of actual measurements, while differences concern the assessment of the requirements of the species as indicators of environmental conditions; or that the scales are different (most often shifted by one degree), while the ecological requirements of the species are similar. The analysis of histograms of frequency for the particular species categories shows that examples supporting the fi rst of the two hypotheses are constituted by the pairs of scales for: (1) light intensity [L] of Ellenberg and Zarzycki, (2) temperature [T] of Ellenberg and Zarzycki; (3) soil moisture [F] of Ellenberg and Zarzycki; (4) nitrogen content in the soil [N] of Ellenberg and Landolt. In terms of the second hypothesis the distribution of frequencies of the species categories in the histograms allows for the explanation of the differences (shifts) within the compared pairs of scales concerning: (1) light [L] as expressed by Landolt or Zarzycki values; (2) continentality [K] of Ellenberg and Zarzycki; (3) soil moisture [F] of Ellenbeg and Landolt; (4) soil moisture of Landolt and Zarzycki; (5) soil acidity of Landolt and Zarzycki; (5) nitrogen content in the soil [N] of Ellenberg and Zarzycki. It is worth noting that similar results for analysis were obtained when the same ecological scales of indicator values were compared by reference to species from meadows of Molinio-Arrhenathereta class (Roo-Zielinska, 2004), deciduous forest of Querco-Fagetea class (Roo-Zielińska 2009) and xerothermic grasslands of Festuco-Brometea class (RooZielińska, 2012). This means that a total of around 380 species (of meadow, deciduous forest, xerothermic and sandy xeric grassland) have now been evaluated, though admittedly this is still only about 20% of K. Zarzycki’s list of Polish flora (Zarzycki et al., 2002). Nevertheless, the ecological spectra and tolerances found for the four groups are very different, with results obtained suggesting the need to continue with the comparative analysis of European ecological scales for groups of species characteristic of different phytosociological units/associations, with appropriate ecological indicator values for Polish flora and plant communities being found in the process.
