查询词典 taxonomic

The characteristic in liquid culture of the purified strains were described, and the relation between the characteristic and the taxonomic traits was researched for the first time. The two groups of Myxobacteria differentiated according to the shape character of the myxospores and vegetative cells had different characteristic in liquid culture.

对纯化菌株的液体培养特征进行了描述，并首次依据初步分类鉴定结果探索了液体特征与分类地位之间的关系，即依据营养细胞和粘孢子形态将粘细菌划分成的两大类型中，第一类型(包括粘球菌属等7个属)的菌株在液体培养基中通常形成片状或絮状，而第二类型(包括单囊菌属等5个属)的菌株则主要呈现球形。

As these groups are often widespread across Asia, full resolution of the nomenclatural and taxonomic problems can only be achieved with a broad revision across many countries.

由于这些组通常在亚洲广布，所以若要完全解决命名法和分类的问题需要进行一跨越很多国家的广泛的修定。

The level, for nomenclatural purposes, of a taxon in a taxonomic hierarchy (e.g. all families are for nomenclatural purposes at the same rank, which lies between superfamily and subfamily).

是指基於命名法的意旨，一个分类单元在分类层系中的位阶例如基於命名法的意旨，所有的科属於同一层级，该层级介於首科和亚科之间。

Results A total of 121 positive clones were randomly screened from the library and 22 Operational Taxonomic Units were determined. BLAST analysis indicated that all OTUs were affiliated with the phylum Crenarchaeota.

从冷泉沉积物古菌16S rRNA 基因文库中随机挑选了121个阳性克隆，共得到22个不同的可操作分类单元，BLAST结果表明全部克隆子归属于泉古菌门中免培养类群。

Taxonomic palaeobiogeography is a kind of palaeobiogeographic discipline which is widely applied in palaeobiogeography. Biotic taxa are the objects in this discipline.

分类群古生物地理学是一种以生物分类单位为研究对象来进行古生物地理区系研究的古生物地理学分支。

Previously, although cluster analysis was applied in taxonomic palaeobiogeography by many authors, the results are not desirable because the genetic and/or family data were collected in the researches.

虽然以前曾有人将聚类分析用于分类群古生物地理学研究，但均以科或属为统计对象，结果都不甚理想。

The birds of Passeriformes are the group which are the largest number, the most species, the highest station of evolvement and the broadest adaptive radiation of existent aves. The traditional taxonomy were onlyaccording to morphologic and behavioral characters, however their morphologic and behavioral characters are so complicated that we could not differentiate some species easily. Therefore we had some taxonomic research by molecular means in order to supply traditional taxonomy.

雀形目是现存鸟类中种类最多、数量最大的、演化地位最高、适应辐射最广的类群，传统的分类方法仅依据形态和行为特征来划分，但由于该类群的形态及行为特征复杂使得部分种类不易区分，因此有必要依据分子手段研究其系统发生关系、以盼能对经典的分类方法给予补充。
