The numbers of newly found individuals and egg sacs of Hynobius tokyoensis during the study periods in 2000 (A) and 2002 (B).. Fig. 2. Egg sacs of Hynobius tokyoensis attached to the underside of a stone. of stones with males were significantly broader than those of stones without males in both years (U-test: z= , P< in 2000; z=, P< in 2002). Likewise, underside areas of stones with egg sacs were significantly broader than those of stones without egg sacs in both 2000 (U-test: z = , P<) and 2002 (z=, in 2000; z=, P> in 2002), although the mean of areas of stones with egg sacs was consistently greater than that of stones with males. Larger stones were used by males in both years with significantly higher frequency (Spearman rank correlation coefficient test, rs=, P<, n=24 in 2000; rs=, , n=32 in 2000; r2=, P>, n=27 in 2002). The number of egg sacs deposited in each hollow was marginally significantly correlated with the underside area of the stone in 2000 {?=0A1, P=, n= 14), but not in 2002 (r^=, P>, n= 14). The water depth in the hollows had a range of cm (x±SD= , n=71) on 8 March 2000, cm (x±SD= +, n=71) on 16 March 2000, and cm (x±SD= +, n=55) on 16 February 2002. The depth of the hollows with males had a range of cm (x±SD=±, n=6) on 8 March 2000, (x+SD = ±, n=ll) on 17 March 2000, and cm (x+SD=±, n=9) on 16 February 2002; the depth of the hollow with egg sacs had a range of cm (x±SD=±, n=5) on 8 March 2000, cm (x±SD=±, n=8) on 17 March.
