P. SÓLYMOS.: Ecological and biogeographical investigation of the recent mollusc fauna of Szársomlyó (S Hungary), southern side

Biogeographical groups Fig. 2. Percentage of biogeographical groups on the S side of Szársomlyó. Legend: A: according to species number, B: according to relative frequency Area Fig. 3. Eveness of the biogegraphical groups On Areas 1 and 2 the number of S, SE Europe species and the frequency of N Alpine, Central Europe and S, SE Europe groups are high. Rate of the other groups are insignificant. On Areas 3 and 4 the S

, SE Europe group rules regardind the number of species and Central, E Europe group rules concerning relative frequency. On these areas the frequency of N Alpine, Central Europe group is high, but not so significant than on Areas 1 and 2. On Areas 5 and 6 the frequency of Holarctic and Mediterrane, S Alpine groups are higher than on the other areas. Regardind the number of species Holarctic and S, SE Europe groups are dominating. The evenness of spreading groups were also examined (Fig. 3.). Area 5 has the highest, and Area 2 has the lowest evenness.
