The radiation of Anolis lizards in the Caribbean is associated with a diversification of the functional match between morphology, habitat use, and locomotor performance. It has been hypothesized that the microhabitat a lizard is reared in can achieve a similar fit of form and function within a species. This predicts that plasticity in the locomotor apparatus is accompanied by changes in perching behavior or improved locomotor performance. To test this, we raised juveniles of two species (Anolis sagrei and Anolis carolinensis) on either broad or narrow surfaces and examined perching behavior and locomotor performance as well as the shape of the pectoral and pelvic girdles, limb length, and thickness of the long bones. Perching behavior was not affected by the habitat surface experienced during ontogeny. However, individuals raised on broad surfaces showed better locomotor performance on broad surfaces, and the magnitude of the effect was as large as the difference between the two species. Both species showed modifications of pectoral and pelvic shape, but only A. carolinensis developed longer limbs on broad surfaces. However, these morphological adjustments induced by physical activity did not explain why lizards raised on broad surfaces performed better. Thus, it appears that early‐life experiences can affect both the morphology of the locomotor apparatus and locomotor performance in Anolis lizards, without the two being functionally connected.

在Anolis蜥蜴中，在熟悉的表面上增强的运动性能与形态可塑性无关。
加勒比地区的Anolis蜥蜴的辐射与形态，栖息地使用和运动能力之间的功能匹配多样化有关。据推测，饲养蜥蜴的微生境可以在物种内达到相似的形式和功能。这预示运动设备中的可塑性伴随着栖息行为的改变或运动性能的改善。为了对此进行测试，我们饲养了两种物种的幼体（Anolis sagrei和Anolis carolinensis）在宽阔或狭窄的表面上，检查其栖息行为和运动能力，以及胸和骨盆带的形状，肢体长度和长骨的厚度。在个体发育过程中，栖息地不受栖息地表面的影响。但是，在宽阔的表面上抚养的个体在宽阔的表面上显示出更好的运动性能，并且影响的大小与两个物种之间的差异一样大。两种物种的胸骨和骨盆形状均发生了改变，但仅卡罗琳在宽阔的表面上形成更长的肢体。然而，这些由体育活动引起的形态学调节并不能解释为什么在宽阔的表面上饲养的蜥蜴表现更好。因此，似乎早期生活经验会影响Anolis蜥蜴的运动装置形态和运动性能，而这两者没有功能上的联系。
