查询词典 species

The spikes per plant of diploid and tetraploidspecies were higher, but the kernels per spike, 1000 kernels weight and grain yield werelower than those of hexaploid and octoploid species. The NYE, NHI and NPE of diploidand tetraploid were lower; NDE was higher than these of Hexaploid. Variation of NPE andNYE was higher than other NUE indexes, which indicated that NPE and NYE could beused as indexes for NUE differences in different wheat related species.

与普通小麦相比，二倍体和四倍体材料单株穗数较多，但穗粒数、千粒重和产量比较低；氮素籽粒生产效率、氮素收获指数和生理效率比较低，具有较高的氮素干物质生产能力；NYE和NPE的变异性较大，可以作为小麦不同近缘种氮素利用效率差异的主要指标。

Taxonomic study, as well as local assemblages of intertidal limpets occurred on rocky shores of Taiwan were conducted. In the taxonomic study, several characters such as shell morphology, coloration of body parts, structure of jaw, odontophore, length and configuration of radula sac and radula formula were applied. As a result, the present study recorded 3 families, 5 genera and 22 species, excluding 3 unknown species of limpets from Taiwan waters.

Most importantly, our team are famous for much research on ecology, physiology,molecular phylogenesis of bats at home and abroad, we have gained much originative result in this field, and we firstly found and studied the third piscivorous bat, Myotis ricketti.We provide evidence that the species Myotis ricketti is piscivorous, and close negative relationships were found firstly within Rhinolophidae and Hipposideridae between call frequency and ear length. Some species of taxology status in rhinolophidae were studied by molecular phylogenesis; phylogenesis relationship between rhinolophidae and hipposideridae and different populations of miniopterus schreibersii were also studied; we also studied Social structure of Tylonycteris pachypusa and T. robustula and the isolating mechanisms of ecological niches.

在蝙蝠生态、生理、和分子系统进化领域完成了大量研究，奠定了本项目组在此领域中的国际地位，首次在国际上证实性发现并系统研究了世界上第3种食鱼蝙蝠--大足鼠耳蝠；首次提出菊头蝠科蝙蝠回声定位叫声频率与耳长负相关；利用分子系统学研究方法澄清菊头蝠科内一些种的分类地位，菊头蝠科和蹄蝠科的关系，以及普通长翼蝠种群间的系统进化关系；系统地研究了扁颅蝠属仅有两个姐妹种的社会组织结构和生态位分化。

主要内容包括：直翅目昆虫群落的结构、区系组成、以及物种多样性，不同生境中昆虫群落的相似性分析，昆虫生态种组的聚类分析，最后讨论了大青沟直翅目昆虫的区系起源演化和大青沟植物群落的起源问题。

By stepwise regression analysis, it shows that there are several vegetation factors, which are grasses height diversity, grasses species number, gompositae dominance degree, gramineae dominance degree and other grasses dominance degree affect the species and numbers of orthopteran.

通过多元逐步回归发现，影响直翅目昆虫种类和数量变化的植被因素有草本植物高度多样性、草本植物种数、菊科优势度、禾本科优势度、其它科优势度。

As a flagship species — one that is popular and the target of conservation efforts — re-establishing oryx populations in the Arabian Peninsula may result in protections for many other species.

作为一种重要物种，一种之前非常普遍的，努力保护的物种，重新在阿拉伯半岛恢复阿拉伯直角羚羊的数量，或许会引起人们对其他物种的保护。

The preserved species may lack genetic representativity because of poor sampling. Inappropriate plantations, inadequate records and unclear kinships jeopardize endangered species to genetic confusion, inbreeding depression or outbreeding depression.

由于引种或取样的不足，容易导致被保存的物种缺乏足够的遗传代表性；盲目的引种、不合理的定植以及材料的来源不清则会导致稀有濒危植物的遗传混杂、近交衰退或杂交衰退；人为选择和生长环境的改变也容易造成濒危物种对迁地保护的遗传适应。
