A beta diversity analysis was made in beech forest coenocline,ranglng from 555 m to 1320 m in elevation,on Mts.Senjo-San and Daisen,western Honshu,Japan.The vegetation was sampled at altitudinal intervals of 60 m to lOO m,with the phytosociological releve method.The populations sampled were treated as(A)phytocoenosis,and as two separate categories of(B)trees and shrubs,and(C)herbaceous plants(incl.liana and dwarf shrubs like chamaephytes occurring in the herb layer of the forest).The beta diversity parameters calculated were ATR(average turnover rate of species along the altitudinal gradient),IA(internal association),HC(Whittaker's half-change),AR50,-80,-95(altitudinal range for 50, 80, and 95％ change in species composition),and ZTR(zone turnover rate of species at individual elevations).The results for the three population categories A, B, and C were,respectively,ZTR =1.12, 0.79, 2.42(×10^-3), IA=1.95, 1.95, 2.00, HC=2.00, 1.42, 4.34, and AR80=642 m, 885 m, 288 m.ZTRs at different elevations were not correlated between the two categogies B and C.
