查询词典 one species

Major results were summarized as follows:(1) A total of 58 tree species from 53 genera in 36 families among which 8 species were Rosaceae, 5 species were Liliaceae, 5 species were Eriaceae, 3 species were Ranunculaceae, 3 species were Compositae, 2 species were Cupressaceae, 2 species were Caprifoliaceae, 2 species were Umblliferae, and other 28 tree species were only one receptively. These were recorded in the 8 plots of the A. georgei var. smithii forest;(2) Number of families, genera, species and Margalef index correlated negatively with altitude (P.05), with a peak at 3600 m.(3) Shannon-Wiener index correlated negatively with altitude (P.01), and maintained stable at the altitudes between 3700~4100 m, evenness with altitudes, however, this trend was insignificant.(4) Jaccard index increased sharply with increasing altitude at the altitudes between 3600~4100 m, and was lower between different vegetation types at the altitudes between 4100~4200. Cody index β(subscript c decreased with an increasing altitude, but there were 2 troughs between 4000~4100 m and 4200~4300 m.(5) Maximum tree height H(subscript max and HH(subscript max=37 mcorrelated negatively with altitude (P.05); but basal area and BA BA(subscript max=5.3m^2 correlated with altitudes, however, this trend was insignificant.

结果表明：(1)在调查的8个急尖长苞冷杉林样地内共有植物58种，分属于36科53属，其中植物较多的科有蔷薇科8种、百合科5种、杜鹃花科5种、毛茛科3种、菊科3种、柏科2种、忍冬科2种、伞形科2种，其余的28科各只有1个种；(2)物种科、属、种数、Margalef指数D(下标 M与海拔存在显著的负相关性(P.05)，在分布急尖长苞冷杉最低海拔3600m处出现物种丰富度的最大值；(3)多样性指数与海拔之间有极显著的负相关性(P.01)，并且在3700~4100m之间多样性指数保持稳定；均匀度指数与海拔梯度之间存在负相关性，但不显著；(4)Jaccard指数C(下标 j在海拔3600~4100m随海拔的升高而升高，在生境过渡带的4100~4200m之间Jaccard指数C(下标 j较低；Cody指数β(下标 c随海拔的升高呈下降的趋势，但在4000~4100m和4200~4300m 海拔区间出现2个低谷；(5)最大树高H(下标 max和最大胸径DBH(下标 max与海拔之间存在显著负相关性(P.05)；胸高断面积之和和立木密度与海拔之间存在负相关性，但不显著。

The results showed that the freshwater species were predominant, and 45 species of algal (5 phylums, 32 genera), in which 18 species of Bacillariophyta belong to 12 genera, 15 species of Chlorophyta one genus, 10 species of Cyanophyta 7 genera, and one specie of Euglenphyta and Chrysophyta; 37 species of zooplankton, in which 9 species of Protozoa, 14 species of Rotifera,...

结果表明，淡水种类占绝对优势，藻类5门32属45种，其中硅藻12属18种，绿藻1属15种，蓝藻7属10种，裸藻、金藻各1属1种；浮游动物共计37种，其中原生动物9种，轮虫14种，枝角类2种，桡足类8种，浮游幼虫及其它4种；底栖动物20种，分别为环节动物的多毛类7种，寡毛类2种，软体动物8种，甲壳动物2种，鱼类1种。

By using the specific PCR primers and T-A cloning, two species of AOB, 1 species of NOB and 11 species of ANAMMOX were detected in the SBBR one-step completely nitrogen removal process. One of the AOBs dominated at this reactor belonged to the family of Nitrosomonas for the similarity of 98% while another one was almost the same with an uncultured one.

同时通过T-A克隆的方法，在系统中发现2类不同的AOB序列，一类与氨氧化菌标准菌株Nitrosomonas有98%的较高相似性，另一类则与其它一种未得到纯培养的AOB接近，相似性为99%。

However remarkable impacts were observed in the plantation in terms of community physiognomy,community structure,species composition,species richness,and biomass accumulation.1 Planting trees made community structure simple.Betula alnoidis plantation had three layers including a dominant arbor layer,a complex and well developed shrub layer and a poorly developed vine layer.The arbor layer contained few species and had a single layer.The mountain rain forest had 4 layers including the dominant arbor layer,shrub layer,grass layer and vine layer.The vine layer was well developed and very rich in species composition,and the arbor layer contained as many as 38 species that could be grouped into 3 layers.2 Sequenced by the important value,main species for the plantation and the nature forest were totally different,and the plantation had one dominant species while the nature forest contained many dominant species.3 Planting trees changed the community physiognomy.

但是人工种植西南桦林对群落的季相外貌、群落的结构、物种组成、物种丰富度以及生物量等方面有较大的影响。1人工造林使得群落结构简化，西南桦人工林的层次结构有3层，以乔木层占优势，并且有种类多而发达的灌木层，同时，藤本植物欠发达，但是乔木层树种单一，明显仅有一层；山地雨林的层次结构有4层，以乔木层占优势，还有灌木层、草本层和藤本植物，藤本植物种类多，十分发达；乔木层树种丰富，可达38种，乔木层还可分为3层。2人工造林较大程度地改变了群落的物种组成，根据重要值的大小排列，人工林和天然林的主要物种组成已经完全不同；并且人工林单优树种明显，而天然林就含有较多的优势树种。3人工造林改变了群落的外貌。

As one species of a large genus of flora growing across Australia, the golden wattle is a symbol of unity.

金合欢是澳大利亚分布极广的一种花卉，它也因此成为澳大利亚统一的标志。

He may choose to specialize on one species of fruit or vegetable or flowering plant.

他可以选择一个专门种蔬菜或水果，或开花植物。

Rebranded might be closer. Taxonomists do not always get it right first time, of course, and what looked like one species may rightly later be seen as two.

当然，物种分类学不可能一步到位，以前曾被归为是同一物种的生物，按新的定义就有可能就被修正2个物种。
