摘要: It is not clear whether Bergmann's rule, larger size within species in cooler areas, holds for any group of ectotherms. Data are presented and used to test amphibians show body-size patterns that follow rule. Available data with respect latitude elevation suggest general 23 34 showing a body at higher latitudes or elevations an overall grand mean correlation coefficient +0.35 elevation. Salamanders consistent the trend, 13 18 having +0.42 Anurans weaker trend towards concordance rule (10 16 species), but significantly positive (+0.31). The relationship between environmental t...
