It shows that the recent rapid decline on population and fragment of habitat leads to indigence in genetic diversity, and all three geographic units exhibits low levels of nucleotide diversity and haplotype diversity. The average genetic distance among all haplotypes was 1.32%, and the genetic variation within and between regions were 99.31% and 0.69% respectively.
结果发现,大鲵近期种群数量锐减和栖息地破碎化以及遗传漂变造成了大鲵遗传多样性的贫乏;三个地理单元均表现出较低的核苷酸多样性和单倍型多样性,各单倍型之间的平均遗传距离为1.32%,99.31%的遗传差异发生地理单元内,仅0.69%发生在单元间。

This paper expounds the reasons behind this laconism and analyzes its relationship with translation diversity. It is concluded that the laconic and ambiguous language style results in diverse versions of translation, which in turn compensates for the shrinking of space for interpretation caused by the employment of explicitation and expansion. The fortunate outcome is that the readers can still appreciate the rich ideas included in sparse language.
文章选取多种英译本中的实例,论述原作语言简约性与《论语》翻译多样性之间的关系,指出语言与语境的简约与含混成就了翻译的多样性,而翻译多样性又弥补了明晰化翻译策略造成的译本阐释空间缩小的问题,目的语读者依然能够感受到原作的辞约义丰。

Podocarpus nagi are the least.(5) Comparing the plant communities from different latitudes, it shows that the rule of community species diversity and community tree layer diversity index change as the latitude changes according with Wlater and Whittakers conclusion about Shannon-Wiener index decrease as latitude increase.
5与不同纬度的植物群落的比较结果表明:群落物种多样性和群落乔木层多样性指数随纬度的变化规律符合Wlater和Whittaker关于Shannon-Wiener指数随着纬度的升高而降低的结论,即与群落物种多样性的纬度趋势一致。

Using a variety of diversity indexes to study the diversity of grasshopper in different habitat region, the results showed that diversity indexof 5 kinds of habitats has the order: crude redeposit broad-leaf weed-tree forest>farmland region>artificial larch tree>lakefront wetland>cutting blank.
采用各种多样性指数对不同生境蝗虫多样性进行了研究,结果显示,Shannon-wiener多样性指数的排序情况为天然次生阔叶杂木林>农田>人工林>湖边湿地>采伐迹地,Pielou均匀度指数变化和H′变化较为一致,相关系数为0.918,达到了显著性水平。

Through individual species-area relationship analysis and Monte Carlo simulation, the species-area patterns from individual view were estimated; as such, every woody species was distinguished as a diversity accumulator, repeller, or neutral species. These species specific characteristics then were treated as implication for the strength of competitive interactions in the study site.
藉由个体物种面积关系分析与蒙地卡罗模拟,我检测个体观点之物种面积关系,并由此将所有树种区分为多样性累积者、多样性排斥者以及多样性中性者三类,再以这些物种特徵来推论种间竞争作用的重要性。
