According to the new vision of the committee, NEON should be focused on the six critical environmental challenges that the nation faces, including biodiversity, species composition and ecosystem functioning; ecological aspects of biogeochemical cycle, ecological implcations of climate change, ecology and evolution of infectious diseases, invasive species and land use and habitat alteration.

新的方案建议NEON应重点关注生物多样性、物种组成与生态系统功能、生物地球化学循环的生态学影响、气候变化的生态学内涵、传染病的生态学和演化、入侵种以及土地利用和栖息地的丧失这6个美国国家层次当前所面临的最严峻的环境挑战。

On earth-and turned old notions about early tetrapod evolution, diver-sity, biogeography and paleoecology on their heads.

其关键的篇章---也转变了人们以往在早期四足动物进化，生物多样性，生物地理学，古生态学的旧的观点和理念。

Biological resources is a core component of the Earth's biological diversity, and it is strategic resources of human existence and development.

生物资源是地球生物多样性的核心组成部分，是人类生存和发展的战略性资源。

The results showed that the free-living marine nematodes were the dominant group the percentage of which in the total number of meiofauna ranging betwean 76.1%~96.3%. The abundance of meiofauna in old mangrove district was the least and in bare beach where waste water flows was the most. There were a total of 37 putative species in the samples. The total number of recorded species was the lowest in the new mangrove district, and highest in the old mangrove district. The species diversity indexes, species evenness indexes and richness indexes in old mangrove district were all higher than those in new mangrove district. The dominant species and feeding types were different in three types of habitats.

结果表明：海洋线虫是凤林红树林中小型底栖动物中的绝对优势类群，占到小型底栖动物的76.1%~96.3%；从丰度来看，旧区白骨壤林中小型底栖动物的数量较少，有污水流过的光滩数量较大；4个断面共鉴定出海洋线虫37种，其中新区秋茄林中的生物多样性指数较低，旧区白骨壤林中群落具有较高的物种多样性；从出现的物种来看，新区秋茄林、旧区白骨壤林和光滩上出现的优势种和摄食功能群的类型各不相同。

Discovery of these microbial information in these unique ecosystems is rather encouraging for further novel species discovery, exploration and conservation of useful microbes. In the first section, the microbiota diversity of the former salterns was investigated by denaturing gradient gel electrophoresis and fluorescence in situ hybridization.

本研究第一部份先以变性梯度胶体电泳(Denaturing gradient gel electrophoresis，DGGE)针对微生物的16S rDNA片段进行分群，再以生物多样性指数加以描述，另辅以萤光原位杂交技术(Fluorescence in situ hybridization，FISH)调查本区域之微生物多样性。

This passage has studied on the biodiversity and its ecosystem service value in the Wuling Mountain nature reserve: 1 Through surveyed and analyzed the overall multiplicity of 7 kind of main forests community types by using the sample plot survey to Wuling Mountain.

本研究采用多种方法对雾灵山森林生物多样性及生态服务功能价值进行了仿真研究： 1。利用样地调查法对雾灵山7种主要森林群落类型的整体多样性进行了调查分析。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.
