无尾类的

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。

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。

By comparison, the biggest rodent alive today is the capybara, which can reach 60kg.

比较起来，当今最大的啮齿类动物是体重可达六十公斤的南美无尾大水鼠。

Along with the economy development, human activities not only straightly threatened the ecological environment but decreased the population number of Anura.

随着经济的发展，人类活动直接威胁着无尾两栖类的生存环境，也造成其种群数量大幅度减少。

Pelobatidae is very importance in the phylogeny of anurans, but the phylogenetic relationships and taxology of this family (including subfamily, genus and subgenus )have yet produced long-time conflicting viewpoint among different researchers both domestic and abroad.

锄足蟾科在无尾两栖类的系统进化中处于极其重要的地位，长期来对该科各亚科、属、亚属的划分以及系统发育关系等问题，国内外学者尚存分歧意见。

"Any of the tailless, anthropoid primate s of two families: Hylobatidae (the lesser apes: gibbons and siamangs) and Pongidae (the great apes: chimpanzees, bonobos, orangutans, and gorillas)."

无尾、类人灵长类的动物，分有两大科：长臂猿科(较小的类人猿：长臂猿和合趾猿)和猩猩科(较大的类人猿：黑猩猩、小黑猩猩、猩猩和大猩猩)。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
