无尾两栖类的

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。

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。

The presence of a mosaic of salientian and caudatan characters in this small fossil makes it a key taxon close to the batrachian divergence.

在这具小化石中兼具无尾目及有尾目两栖类的特征，因此它是接近于蛙形两栖类分歧的关键类群。

Sixteen ( 15 new) amphibian and twenty-two ( 11 new) squamate species have been reported across China, including the oldest Chinese tetrapod Sinostega pani from the Late Devonian of Ningxia Hui Autonomous Region, the large stereospondyl amphibian Yuanansuchus laticeps from the Middle Triassic of Hubei Province, Late Jurassic/Early Cretaceous lissamphibians ( e. G., the anurans Callobatrachus sanyanensis and Mesophryne beipiaoensis, the caudates Jeholotriton paradoxus and Laccotriton subsolanus) from Northeast China, Paleogene lizards (e. G., Brevidensilacerta xichuanensis and Tinosaurus yuanquensis) from North China, and numerous lizards from the Late Cretaceous of Nei Mongol Autonomous Region.

共报道了16种两栖类和22种有鳞类，其中15种两栖类和11种有鳞类为新种，包括我国最古老的四足动物宁夏晚泥盆世的潘氏中国螈，湖北中三叠世的大型全椎两栖类宽头远安鲵，东北晚侏罗世/早白垩世的多种滑体两栖类(如无尾类三燕丽蟾和北票中蟾，有尾类奇异热河螈和东方塘螈)，华北古近纪的蜥蜴类(如淅川短齿蜥和垣曲响蜥)，以及内蒙古晚白垩世的多种蜥蜴类等。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
