    Calibration of pollen spectra in terms of species abundance.

    , Palaeohydrological changes in the temperate zone in the last 15 000 years. IGCP 158 B. Lake and mire environments. Project guide III, Pages: 25-51

    Describes calibration techniques which make it possible to translate pollen spectra (relative or absolute) into quantitative estimates of plant taxon abundances. Covers the methodology of surface sample surveys, the empirical methods used to derive correction coefficients from surface pollen and quantitative vegetation data, and the reconstruction of past vegetation. -K.Clayton

    Phytosociological studies at malham tarn moss and fen, Yorkshire, England

    , Vegetatio, Vol: 30, Pages: 117-132, ISSN: 0042-3106

    During a field course the vegetation of the extensive mire complex on the west side of Malham Tarn was examined. 84 relevés were collected, with 210 taxa in total. This data set has been 'structured' by classical phytosociological techniques. It is suggested that it approaches the maximum size of data-set which can be handled in this way, especially if the data are not all collected by one person. Ordination of the quadrats was carried out but gave little insight into the data despite the use of non-centred as well as centred principal components analysis. Numerical classification of the quadrats using minimumvariance cluster analysis was shown to produce a structure interpretable in ecological terms. A classification of the taxa was carried out by the same method and a 'rearranged' table was drawn up using the results of the two classifications. A relocation technique was applied at an appropriate cluster level but little was felt to be gained from this. The use of 'two-way' minimum-variance cluster analysis for the rapid production of re-arranged tables is recommended for large data-sets. In addition the vegetational units recognised in the data are described and discussed. © 1975 Dr. W. Junk b.v. Publishers.
