These areas are not just attractive for their beauty, they're also critical transition zones from marine to terrestrial and freshwater habitats, and are the sites of nurseries for a host of marine species in the form of salt marshes and eelgrass beds.

因为这些地区不仅仅风光秀丽同时还是海洋到陆地和淡水栖息地的关键过渡区。同时这些地区的河床和盐沼是海洋的主人——各类海洋生物形成的摇篮。

With the ethnographical approach focusing on the changing mode of production, I aim to understand the rippling effects of crayfish farming on people's changing life styles, changes in values, and formation of policies and meanings.

中国贝类学的研究范围涵盖古贝类和现生贝类（陆生贝类、淡水贝类、医学贝类和海产贝类），涉及的研究方向有：古贝类进化与环境变迁，形态、区系、生物多样性及其保护，遗传育种及其安全性，病害，养殖与生态环境等，取得了丰硕的研究成果，促进了我国贝类学理论和相关技术的应用与发展。

The Recent freshwater ichthyofauna from the Japanese islands is, in many respects, different from that of eastern China.

日本列岛和中国大陆东部的现生淡水鱼类区系存在显著的差异，但这两地上新世和中新世的鱼类区系已发现的组成成分却似乎比现代鱼类区系要接近得多。

Gross of natural resources of water of catchment of the Yangtse River 996 billion stere, 35% what take the throughout the country, at present development utilization rate has 18% only, divide outside propping up this catchment to use water, still pass in carrying out south project of water north attune is northwardly provide fresh water resource, its moist limits involves 26 provinces city, shortage of gross of this pair of water, and distributing very not all China has fundamental strategic value.

长江流域水资源总量9960亿立方米，占全国的35%，目前开发利用率只有18%，除支撑本流域用水外，还通过实施中的南水北调工程向北方提供淡水资源，其润泽范围涉及26个省市，这对水总量短缺、且分布极为不均的中国具有重要的战略价值。

The spiny eel , belonging to Perciformes, Osteichthyes, is a kind of little freshwater fish distributed in Southern China. In 1998, Our lab detected XX/XY differentiated sex chromosomes in this specie with karyotypic analysis, and then with chromosomal binding and SC observation, we identified that its two largest metacentric chromosomes were X, Y sex chromosomes in 1999. X, Y chromosomes differ each other not only in the distribution of heterochromatin but also in their shapes, which make them could be recognized directly under the light-microscope without any banding treatment.

刺鳅，属鲈形目、刺鳅科(Perciformes，Mastacembelidae)，是广泛分布于中国南方的小型淡水鱼类。1998年，我室通过核型分析，首次发现该物种具有明显分化的异形性染色体，其性别决定类型为XX／XY型。1999年，本室通过染色体显带、精母细胞联会复合体观察，再次确认刺鳅染色体组中最大的一对中部着丝粒染色体为X、Y性染色体，两者不仅已经出现结构异染色质分布上的不同，同时在外部形态上也存在明显差异，识别特征鲜明，在光镜观察下无需显带即能清晰辨认性染色体。

Government efforts to increase domestic agriculture are complicated by the paucity of fresh water in this parched desert nation.

政府努力增加国内的农业科学是复杂的由于缺乏淡水在这个炎热的干透的国家。

Effect of phenol on performance of MFCs was investigated.

结果表明，在淡水沉积物接种的微生物燃料电池中，电流的产生是由富集在电极表面的细菌引起的。

The cybernetic difference between an organism such as a pollywog and an ecosystem such as a fresh-water bog is that an organism is tightly bound, and strict;an ecosystem is loosely bound, and lax.

从控制论的角度看，象一条蝌蚪这样的有机体和一片淡水沼泽这样的生态系统之间的不同在于，单个有机体对内紧密束缚、严格控制，而一个生态系统对内则很宽松约束、不易控制。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
