多样性

The number of species, species diversity and G-F index in the primary forest are the highest. The birds in that community has more species, families and genus, but the number is less.

原生林的鸟类物种数、物种多样性及G-F指数最高，该群落的鸟类在物种和科属水平上拥有最高的多样性，但是个体数量较少。

The results showed that the Shannon-wiener diversity index of forest plant species increased with the increase of the environmental gradient, and the β-diversity indexes of communities showed a liner increase along with the change of environmental gradient.

In this research, we summarize the genetic diversity and evolutionary origin of yellow cattle landraces in China from two aspects of morphology diversity and its specific microsatellite markers of Y chromosomes.

本文主要从Y染色体的形态多样性和Y染色体特异性微卫星标记遗传多态性两个方面对中国地方黄牛的遗传多样性和进化起源进行了综述。

There was not significant difference between rainy seasons and dry seasons both in diet diversity index and plant species used. It indicated that langurs fed on similar number and proportion of plant parts.

月食物种类与食物多样性指数呈显著正相关(Spearman' rho r=0.756， p=0.007.05)，表明黑叶猴把大部分取食时间集中在少量食物种类时，其食物多样性指数最低；反之最大。

Forests of the tree layer show the highest diversity and evenness, while artificial larch forests, artificial Korean pine and Mongolian oak forests show much less diverse and less even.

杂木林的灌木层多样性最高，岳桦林的均匀度指数较高。蒙古栋林的优势草种比较明显，各多样性指数在所有样地中均达到了最低水平。

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。

Genetic diversities in Japonica were different among rice zones and subzones, and decreased from south to north in general.

以省份为稻作区域的划分标准时，各省份的基因多样性以及籼粳遗传分化南方省份间相当，北方省份间的差异稍大，但与以稻区及亚区为划分标准相比基因多样性有所降低，遗传分化系数有所升高。

Diversity of mineralization is an essential phenomenon in ore forming process.

1 成矿多样性问题多样性是复杂系统中客观事物外在表现的基本特征，它是系统内部各种因素自身演化与外部环境影响相结合的结果。

Soil samples from three salterns were analyzed using DGGE representing 5 archaea and 18 bacteria taxonomic groups, whereas 8.7% of microbes were unclassified microorganisms. During FISH analysis, several taxonomic-specific probes were used.

经由DGGE分析得出24个分群中，有19属的细菌和5个属的古生菌，此外有8.7%的菌群是未知菌种；多样性指数演算结果指出，七股盐田具有最低的微生物多样性。

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。
