Comparative ecological and animal geography malacological screening of ravine forest in the Bükk and Mecsek mountains

The authors carried out a comparison between two types of ravine forests to be found in the north and south of Hungary, in two different flora areas (Matricum, Praeillyricum). The ratio was found similar both regarding the distribution of type habitat and of the sum values of fauna areas. In contrast to 48 species in six places of collecting in the Bükk, 43 species in 11 places in the Mecsek were found. Equally 7,80% difference was discovered between continental and subatlantic fauna areas. Ecologically shrubby forest (B) forest dwellers (HF) dominate and the groups of types of habitation were proportionally similar. As to animal geography in the Bükk East-Sibirian and Holarctic (1.1, 1.4), Illyr-Moeziac (5.1.2.2) fauna areas are dominant, elements od difference are the existence of Boreo-mountaneous (10.2) and Karpathian connections (9.1, 9.2, 9.3, 9.4) and the non-existence of Atlanto Mediterranean fauna areas. In the Mecsek the element of differentation is the presence of 1.4, 5.1, 5.2.2 dominating fauna areas and that of the Atlanto Mediterranean (7) one. On the whole a more marked similarity can be pointed out ecologically. A similarity with plant coenosis is the frequency in the Bükk of Balcanic and Boreal elements while in the Mecsek Illyr and Submediterranean elements (Soó 1964), What responds to differences in malacologic animal geography
