    Abstract : Studies of the small-scale pattern, mobility of plant species and the effects of cattle dung deposition and decomposition on the soil seed banks and the above-ground vegetation were carried out in an alvar limestone grassland in Gettlinge, on the Baltic island of Öland, Sweden.A new method for pattern detection using transect data Patch Size Frequency Analysis (PASFRAN), was developed.

  4. 2. From pattern to process : Studies on limestone grassland, with emphasis on the bryophyte-lichen layer and its effects on vascular plants

    Abstract : Patterns in space and time at different scales in the bryophyte-lichen layer, aud multi-species spatial patterns of bryophytes, lichens and vascular plants were studied in Avenetum limestone grassland on the Great Alvar of the Baltic Island of Öland, south-eastem Sweden.Spatiotemporal patterns of bryophytes and Iichens in grazed and ungrazed alvar grassland demonstrated that dominant species forming large patches were relatively stable in time, whereas less frequent species forming small patches were more mobile.
