| 中文摘要: |
| 采用扫描电镜和组织学技术观察了中国林蛙(Rana chensinensis)蝌蚪发育过程中口器外部形态结构的变化,以及中国林蛙蝌蚪口器内部结构特征。结果表明,在口器发育的初期,角质颌最先出现,接着出现唇乳突以及唇齿;在变态高峰期(G41~G42),口器结构如唇齿、角质颌和唇乳突则是按以下顺序消失的,即唇齿最先消失,其次角质颌消失,最后唇乳突消失。通过与其他无尾两栖动物幼体蝌蚪口器的结构比较,表明唇齿行和角质颌形态结构的发育与蝌蚪的觅食行为以及食物类型都是密切相关的。最后探讨了中国林蛙蝌蚪的取食方式和食物转运摄食途径。 |

| The alterations of oral apparatus morphology of Rana chensinensis tadpole were observed using both electron microscopy and light microscopy.The results showed that jaw sheaths appeared firstly at embryo stage,followed by the formation of marginal papillae and tooth rows.However,the tooth rows disappeared,followed by the lost of jaw sheaths and marginal papillae during metamorphic climax stage (G41-G42).Compared to the other anuran larvae,morphological structure of oral cavity was related with the feeding behaviors and food types in Chinese Wood Frog tadpole.Finally,the feeding mode and food transport in the tadpoles of R.chensinensis were discussed. |
