Természettudomány - Kiss Tamás: Az Alpokalja epifiton zúzmóvegetációjának mennyiségi és minőségi elemzése

THE QUALITATIVE AND QUANTITATIVE ANALYSE OF EPIPHYTIC LICHENS OF THE ALP FOOT-HILLS VIEWING THE HOST SPECIFICITY OF SPECIES T. KISS The author hass made a quantitative and qualitative study about the lichen vegetation of Praenoricum and the hungarian part of plant-territory of the Noricum. To the analyse was used not only the new data, but some informations of the lichens-literary, too. In the establishment of similarity of the lichen vegetation between different tree species was used the Sörensen-indices. The author has elaborated the life-form structure of the lichen vegetation of all the trees. The results have showed that the texture of the bark Is an important ecological factor for epiphytic lichens. The smooth bark trees and the cracked bark trees have presented significant differences in their lichen vegetateon and lifeform structure. Especially the stumps of Castanea and Pinus have an interesting lichen vegetation and life-form structure, due to the construction of the decaying bark. (Tables: 1, 2 and 3.) From the standpoint of host specificity — according to the opinion of the author — the investigations has pointed out that this problem may study through the life-nform structure and the aid of Sörensen-indices only, if we have enough data.
