查询词典 phylogenetic

Has the orb-web a monophyletic or a polyphyletic origin? In other words, is Orbiculariae (Deinopoidea + Araneoidea) monophyletic or polyphyletic? There is a considerable dispute about phylogenetic relationship between Deinopoidea and Araneoidea.

In the present study, mitochondrial 12S, 16S and nuclear 18S, 28S rDNA fragments of ten species of spiders were amplified and sequenced. Using neighbor-joining, maximum parsimony, maximum likelihood methods and Bayesian analyses, the phylogenetic relationship between Deinopoidea and Araneoidea was inferred from the combined DNA sequences of 12S, 16S, 18S and 28S rDNA fragments. The resulting phylogeny indicated that: Deinopoidea and Araneoidea did not form single clade.

本论文以安琪酵母股份有限公司有代表性的酿酒酵母属中24株酿酒酵母及相关3种子囊菌酵母为研究对象，通过对所选取酵母菌株的核糖体DNA ITS-1序列进行电泳和克隆测序，分析出它们之间的系统学关系。

All evidences from both phenetic classification and cladistic classification demonstrated that the matsutake group is a polyphyletic group and Tricholoma nauseosum, T. matsutake and T. matsutake var. formosa come from one line of descent; T. focale, T. robustum and T. fulvocastaneum are closely related; T. zelleri, T. aurantium, T. caligatum var. nardosmia formed a clade. The result also suggested Dollo parsimony criterion was more suitable for phylogenetic reconstruction of the matsutake group based on morphological characters than the other two criterions.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。
