Influence of hydrometeorological hazards and sea coast morphodynamics on development of Cephalanthero rubrae-Fagetum (Wolin island, the southern Baltic Sea)

摘要

Climate changes, sea transgression and sea coast erosionobserved today cause dynamic changes in coastal ecosystems. In theelaboration, cause and effect interrelations between abiotic hazards(hydrometeorological conditions and sea coast morphodynamics) and biotic(Cephalanthero rubrae-Fagetum phytocoenosis) components of natural environment have been defined. Anup-to-date phytosociological analysis of a very valuable Cephalanthero rubrae-Fagetum site on clifftableland was conducted in the context of hitherto temporal variability ofclimatic conditions and the rate of cliff coast recession. Also, thedevelopment prognosis of the researched site in the 21st century isprovided, with respect to the expected climate changes and cliff'smorphodynamics. The conducted research actions revealed the influence ofglobal hazards (e.g. climate changes, sea transgression and sea coasterosion) on changes in the natural environment on regional scale (with theexample of the site of Cephalanthero rubrae-Fagetum on a cliff coast of Wolin island in Poland). It hasbeen established that in the 21st century, a relatively larger hazard to thefunctioning of the researched site is climate changes (i.e. mostly changesin thermal and precipitation conditions) not the sea coast erosion.
