摘要

Abstract > Skeletal morphology is directly associated with habitat characteristics. To investigate the arboreal adaptation, we studied the osteological morphology of the forelimbs and the third metacarpals of arboreal frogs (Rhacophoridae and Hylidae) and non‐arboreal frogs (Bombinatoridae, Bufonidae, Megophryidae, Ranidae, and Microhylidae) using transparent specimens or X‐rays of skeletons. Our results revealed that the bony knob on the third metacarpal, which formed by a dilated and elongated lateral articular cartilage ( <fc>AL</fc> ) through endochondral ossification, occurred only in species of Rhacophorinae. The results of the phylogenetic comparative methods and correlation analysis strongly supported the conclusion that the bony knob is a phylogenetic independent evolution trait and had a significant correlation with the arboreal habitat. Furthermore, anatomical observation showed that a muscle adhered to the bony knob. Therefore, we speculated that the bony knob might act as an enlarged attachment point for larger or more musculatures to help with grasping. In addition, the relative length of the hand showed a significant difference between arboreal and non‐arboreal species ( p? = ? .007), suggesting that longer hands might be an arboreal adaptive trait. Overall, this study leads to a deeper understanding of the arboreal adaptation. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> <div

p>骨骼形态与栖息地特征直接相关。为了探讨树栖适应，我们研究了使用透明标本或X射线的植物青蛙（rhaCophoridae和Hylidae）和非树栖青蛙（Bompinatoridae，Bufonidae，Megophyidae，Ranidae和Microhylade）的骨质学形态学骷髅。我们的研究结果表明，第三款Metacarpal上的骨旋钮，其通过脱噬细胞骨化的扩张和细长的横向关节软骨（<Fc> Al </ Fc>）形成，仅在rhacophorinae种中发生。系统发育比较方法和相关分析的结果强烈支持结论，即骨旋钮是系统发育独立演化性状，与树栖栖息地具有显着相关性。此外，解剖学观察表明，肌肉粘附在骨旋钮上。因此，我们推测骨旋钮可能是较大或更多肌肉的放大附件，以帮助抓住抓握。另外，手的相对长度显示了树栖和非树栖物种（p≤C= 〜> .007）之间的显着差异，表明较长的手可能是一个树栖自适应特质。总体而言，这项研究导致对树栖适应的更深入了解。 </ p> </ abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2
