Samenbank und Vegetationsaufnahmen ostmediterraner Therophytenfluren im Vergleich

Abstract

In a rural Turkish settlement within the eumediterranean coastal belt near Antalya, soil samples were taken for determination of the seedbank and in addition to phytosociological investigations. This measure was taken to obtain more precise information about the potential species composition and the seasonal vegetation dynamics. During a period of 16 months, germination experiments have been carried out at the Institute of Ecology at the Technical University of Berlin, Berlin (West). 1714 seedlings were counted, of which 245 died unidentified. A number of 1469 (85,7 %) seedlings had been recognized and classified into 83 species. The indentified plants were classified and grouped as character-species of the Macchie and their derivates, esp. the community of overgrazed pseudo-steppic vegetation (Trift), trampling, ruderal and weed vegetation of arable fields and compared with vegetation relevés of the soil sample areas. 35 species were found only in the soil samples. This resulted in a mean correspondence of 58% between seedbank and vegetation. It is being discussed why seedbank species could not be found in the vegetation, whereas others with a high cover value had no seed depositions in the soil.
