我们检查了来自三个科的 14 种有垫蜥蜴的附着能力、趾垫面积和体重，以检验三个预测：（1）附着能力和垫面积在物种之间应该紧密相关； (2) 14 个物种的垫面积和粘附能力应与体重相似； (3)尽管体重存在差异，但物种之间在粘附能力方面应该存在功能相似性。我们的结果证实了两个预测：即使消除了体型大小的影响，粘附能力也与垫面积密切相关，并且所检查的蜥蜴的粘附能力在功能上大致相似。然而，尽管脚垫面积和粘附能力之间存在紧密相关性，但脚垫面积与体重的比例关系比粘附能力的斜率更低。总的来说，这些结果表明，虽然垫面积是粘附能力的重要决定因素，但其他因素使这些蜥蜴能够保持功能相似性。
We examined clinging ability, subdigital pad area and body mass in 14 pad-bearing lizard species from three families to test three predictions: (1) clinging ability and pad area should be tightly correlated among species; (2) pad area and clinging ability should scale similarly to body mass among 14 species; and (3) functional similarity in clinging capabilities should exist among species despite differences in body mass. Our results confirm two predictions; clinging ability is tightly correlated with pad area, even when the effects of body size are removed, and the lizards examined are approximately functionally similar in their clinging capabilities. Nevertheless, despite the tight correlation between pad area and clinging ability, pad area scales with body mass by a lower slope than clinging ability. Overall, these results indicate that although pad area is a strong determinant of clinging ability, other Factors enable these lizards to maintain functional similarity.
