两栖类

Chapter 2: The phylogeographic researches on Anuran amphibians in the world including China are reviewed.

第二章：对国内外的无尾两栖类的系统地理学研究进行了综述。

Vocal behavior is universal in anuran amphibians and is very important for their reproduction.

鸣叫行为是无尾两栖类动物常见的行为，对其生存和繁殖具有重要意义。

In recent years, many toxicology studies have been carried out with anuran tadpoles in China, since they are believed to be perfect indicator species for aquatic pollution.

中文摘要：无尾两栖类的幼体蝌蚪是很好的水体污染指示物种，近年来，国内这方面的研究也越来越多。

Although there is no consistent evidence, many researchers suggested that vocal behavior of anuran amphibians were closely related to the circulating levels of sexual hormones.

虽然目前没有一致的证据，但研究结果暗示了很多无尾两栖类动物的广告和攻击鸣叫行为与其体内雄激素水平密切相关。

Blood oxygen capacity of Bufo bankorens is high compared with other anuran amphibians, which benefits their living at high altitude.

盘古蟾蜍血液携氧力比其他两栖类强，有助於生存在高海拔氧气较低的环境。

The niche breadths of adults and subadults of three anuran species (Rana kukunoris, Nanorana pleskei and Bufo minshanicus ) in Zoige Wetland Nature Reserve, Sichuan, China were studied. The results showed that the niche breadths of B. minshanicus adults on the 5 dimensional axes including character of pasture, number of yak dung, vegetation coverage, temperature and humidity of ground surface, were narrower than those of R.

研究了若尔盖湿地国家级自然保护区的3种无尾两栖类，高原林蛙、倭蛙和岷山蟾蜍的成体和亚成体在7个生境因子(牧场性质、牛粪数量、植被高度、植被盖度、距水塘距离、地表温度、地表湿度)上的生态位宽度。

After lentectomy through the pupillary hole, the epithelial cells at dorsal iris in Anuran tadpole of Bufo raddei Strauch can undergo transdifferentiation to regenerate a new lens. The morphological changes of lens formation from different regeneration stages were observed with both microcope and transmission electron microscope.

以无尾两栖类花背蟾蜍后肢芽期蝌蚪为实验材料，摘除其左眼晶状体，在再生不同时期固定，石蜡连续切片，苏木精-伊红对染，光镜观察，研究晶状体再生的组织来源；另外，选再生不同时期材料用戊二醛，锇酸固定，透射电镜观察，以研究晶状体再生组织的超微结构变化。

The left lens of Anuran Tadpole - Bufo Raddei Strauch Tadpole and Xenopus laevis Tadpole were removed when they had posterior limb bud. By decapitating and fixing it with Carnoy's fixation fluid in different days, by means of paraffin serial section and Hematoxylin-Eosin stain and by using the microscope to observe the microstructure of lens regeneration of Bufo Raddei Strauch Tadpole and Xenopus laevis Tadpole. By extirpating the left eye and fixing it with aldehyde and osmium acid , by using electron microscope to observe the ultrastructure of lens regeneration of Bufo Raddei Strauch Tadpole and Xenopus laevis Tadpole.

以无尾两栖类—以花背蟾蜍与非洲爪蟾后肢芽期蝌蚪为实验材料，摘除其左眼晶状体，在再生不同时期固定，石蜡连续切片，苏木精-伊红对染，光镜观察，研究晶状体再生的组织来源；另外，选再生不同时期材料用戊二醛，锇酸固定，透射电镜观察，以研究晶状体再生组织的超微结构变化。
