    On the delimitation of the Mesobromion and Xerobromion in Belgium and French Lorraine (1989)
    Springer
    Plant ecology 81 (1989), S. 137-144

    ISSN: 1573-5052
    Keywords: Brometalia ; Canonical correlation ; Classification ; Discriminant analysis ; Oridination ; Soil parameter

    Topics: Biology
    Notes: Abstract Within a broader study of the chalk and limestone grasslands in Belgium, Luxemburg and northern France, the limestone grasslands of the Meuse valley in Belgium and in French Lorraine were investigated. Floristic data as well as environmental variables were taken into account for the delimitation of species and relevé groups. Discriminant analysis and canonical correlation analysis proved to be very helpful in the interpretation of the detected groups as well as for the reconsideration of interrelationships between recognised syntaxa. The present results are consistent with the hypothesis that the limestone grasslands in French Lorraine, even those previously assigned to the Xerobromion, belong to the Mesobromion, and that the limestone grasslands in Belgium belong either to the Mesobromion or to the Xerobromion in an impoverished form.

    Studies on the possible role of cation exchange capacity in the soil preference of mosses (1983)
    Springer
    Plant and soil 70 (1983), S. 77-93 
    Details
    ISSN: 1573-5036
    Keywords: Adsorption ; Calcium ; Calcium carbonate ; Cation Exchange Capacity ; Hydrogen ; Magnesium ; Moss ; pH ; Potassium ; Sodium ; Soil preference

    Notes: Summary Moss species with a different soil preference with respect to its acidity and carbonate content also differ in their cation exchange capacity (leaf, stem, rhizoid), the acidiphile-calcifuges having lower C.E.C. values than the neutrophile-calcicoles. The higher the C.E.C. value, the more the divalent cations calcium and magnesium tend to be adsorbed as compared to the monovalents sodium and potassium, from an equinormal tetracationic solution. The increase in divalent adsorption is mainly due to calcium. Considering this differential adsorption of calcium and in view of data in literature on membrane characteristics, it appears that among the studied cations calcium is an important factor in the observed soil preference through its presence in the cell wall adsorbed fraction and thus in the membrane environment.

    Soil preference of populations of genotypes ofAsplenium trichomanes L. andPolypodium vulgare L. in Belgium as related to cation exchange capacity (1983)
    Springer
    Plant and soil 72 (1983), S. 275-282 
    Details
    ISSN: 1573-5036
    Keywords: Aluminium ; Asplenium trichomanes ; CaCO3 ; Calcicole ; Calcifuge ; C.E.C. ; Fern ; Hydrogen pH ; Polypodium vulgare ; Soil preference ; Subspecies

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Abstract A number of populations ofPolypodium vulgare L. andAsplenium trichomanes L. were sampled with corresponding soils in Belgium in order to get an idea of their suitability for the investigation of related calcicole and calcifuge taxa. Morphology and cytology enabled us to distinguish the subspecies and the hybrids. Analyses of the soils for pH, CaCO3, Al and H show that subspecies and hybrids have distinct soil preferences and can be characterised as calcicoles-neutrophile/basiphiles or calcifuge-acidiphiles. Physiological implications of the ecological status of the taxa are discussed in the light of their root cation exchange capacity.
