RELATIONSHIP BETWEEN POLLEN AND FLORISTIC DIVERSITY IN THE RECENT LAKE SEDIMENTS AND MOSS POLSTERS IN CENTRAL EUROPE

Popis výsledku v původním jazyce

Palynological reconstruction of Holocene vegetation changes requires understanding of crossscale relationships between floristic and pollen diversities. We explored the relationships in two regions differing in dominant vegetation and diversity patterns. The White Carpatians are a biodiversity hotspot of thermophilous vegetation comprising dry-mesic grasslands and broadleaved forests, while the Bohemian-Moravian Highland is dominated by species-poor coniferous forests, meadows and wetlands. In each region, 40 sites covering the major habitats were sampled for plant and pollen diversity. A detailed floristic survey in radii of 10 and 100 m and in two transects of 1,000 m was conducted at each site. Recent pollen diversity was sampled by gravity corer in ponds and quarries in the Bohemian-Moravian Highland at 20 sites. The rest of sites were moss polsters taken in the centre of each site. Altogether, 1260 plant species were recorded and more than 219 pollen taxa were identified. The total number of plant species was similar in both regions (942 species-poor region and 965 species-rich region), but number from Bohemian-Moravian Highland is biased large area surveyed around water deposits. When selecting 20 terrestrial sites with equal vegetation sampling effort and rarefied pollen sum to 827 pollen grains, we obtained expected pattern.
