Body size also differed significantly between the two species: R. sakuraii v^diS, on average, at least IQo/o larger than R. l tagoi (Table 1). In addition, SVL differed significantly between the two populations oiR. sakuraii. Since clutch parameters of amphibian species, such as egg size and clutch size, often show significant cor- relations with female body size (, Kuramoto, 1978; Kaplan, 1980), effects of variation in female size should always be considered when comparing those clutch parameters between populations. 250 O 200 150 100 50 « R. sakuraii (BONBORI) O R. sakuraii (TOCHIGI) A R. tagoi (ICHINOSAWA) â² R. tagoi (KAMIANGE). 35 40 45 50 55 SNOUT-VENT LENGTH (mm) Fig. 3. Relationship between female body size and clutch size in four populations of Rana sakuraii and R. t. tagoi. Regressions of the four populations differed significantly in elevation. Solid lines denote regressions for Bonbori (Y=, r=, n=41: above) and Tochigi (Y=, r=, n=14: below) populations of R. sakuraii. Dashed lines denote regressions for Kamiange (Y= 207, r=, n=18: above) and Ichinosawa (Y= X-214, r=, n-34: below) popula- tions of R. L tagoi. Females of both species showed a significant positive correlation between clutch size and SVL (Fig. 3). The ANCOVA showed that R. sakuraii deposited a fewer number of eggs for body size than R. t. tagoi: the adjusted means were , , , and at Bonbori, Tochigi, Ichinosawa, and Kamiange, respec- tively.
