两栖类的

Here is a present for surviving the fish age. it is the body of an amphibian.

这里有奖励你从鱼类时代生存下来的一件礼物——两栖类的身体。

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。

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。

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。

Phylogenetic analysis suggests that the batrachian divergence occurred in the Middle Permian, rather than the late Carboniferous as recently estimated using molecular clocks18, 22, but the divergence with caecilians corresponds to the deep split between temnospondyls and lepospondyls, which is congruent with the molecular estimates.

谱系分析认为蛙形两栖类的分歧应发生于二叠纪中期，而不是石炭纪末。然而，与离片椎类和壳椎类这一意义深远的分歧密切相关的事件——蛙形两栖类与无足目的分歧的时间却与分子钟所估计的相符。

Silurian'.'' and before the Mississippian or Carboniferous Period, and characterized by the appearance of forests and amphibians.

处于志留记之后，密西西比纪或石炭纪之前，森林和两栖类的出现是其特征

Metaphase chromosomes showing multiple banding pattern were easily reproducible using BrdUrd-Hoechst-Giemsa technique in Amphibia.

BrdUrd-Hoechst-Giemsa技术在两栖类的中期染色体上能显示可复重的复合带型。

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。

It indicated that protection and improvement of the diverse habitats was an important measure to protect local amphibians.

研究结果表明，保护和改善多样性生境是保护当地两栖类的重要措施之一。

The answer was that the former could be far sensitive than the latter, but the former needed complex instruments. The latter could help us to directly judge the order of severity by colors.On the other hand, we took advantage of polymerase chain reactionto amplify the MCP genome of the virus and compare it with other nine published MCP genomes of viruses including CzIV, TIV, CIV, LCDV-1, LCDV-K1, BIV, FV3, GIV, RSIV. The sequencing data showed that the MCP of Cobia iridoviruswas more homologous to the MCP of LCDV-1（89﹪similarity）than that from FV3（47﹪similarity）.

另一方面，为了了解引起海鲡病变之病毒究竟属於何种病毒，我们透过聚合酶链锁反应增幅其主要鞘蛋白基因并加以定序，与其他九种已发表的虹彩病毒之 MCP 核酸及胺基酸序列，包括：CzIV、TIV、CIV、LCDV-1、LCDV-K1、BIV、FV3、GIV、RSIV 之 MCP 进行分析比对，显示 Cobia iridovirus亲缘性和感染大多数硬骨鱼类的 Lymphocystivirus 属的 LCDV-1 最为接近（89﹪相似度），和感染两栖类的 Ranavirus 属的 FV3 亲缘性较低（47﹪相似度）。

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。
