查询词典 phylogenetic development

The phylogenetic-tree analysis demonstrated that in Arachis the FAD sequence was conservative and highly homogenous to those in other species.

系统进化树分析表明，FAD序列在花生属植物进化过程中较为保守；与其他物种的FAD序列也具有较高的同源性。

The journal well informs the research advances in all aspects of arachnology, including spiders' research, structural analysis, phylogenetic reconstruction, habitats, behavior and the introductions of some new species etc.

该杂志全面提供了节肢动物学各方面的研究进展，包括蜘蛛研究、结构分析、系统发生重建、动植物生活环境、行为学以及一些新种的介绍等等。

The resulting phylogeny indicated that:(1) Araneidae and Tetragnathidae, which build orb webs, are not a sister group in the superfamily Araneoidea;(2) Theridiidae and Linyphiidae, which build nonorb webs, are also not monophyletic, The results also corroborated the independent origins of linyphiid sheet webs and theridiid gumfoot webs;(3) The phylogenetic placement of linyphiid closer to tetragnathid than to araneid implies that the similarities of male palpal organ between linyphiids and araneids may be homoplastic rather than homologous.

结果表明：(1)织圆网的园蛛科和肖蛸科蜘蛛在园蛛总科里不是姊妹群；(2)不织圆网的球蛛科和皿蛛科也不是单系的，进一步证实了皿蛛片网和球蛛网独立起源的观点；(3)皿蛛科蜘蛛的分子系统发生地位与肖蛸科较近而与园蛛科较远表明皿蛛科和园蛛科间雄性触肢结构的相似性很可能是类似而不是同源相似。

Historically the arctiid Syntominae was often confused with Zygaenidae, Sesiidae, Euchromiini and Ctenuchini due to the convergent wing shape and colour patterns. According to the phylogenetic hypothesis being more accepted in recent years, the subfamily comprises two tribes, the pan-Old World Syntominiand the Africa-restricted Thyretini.

鹿蛾亚科(Arctiidae： Syntominae)在研究历史上常与斑蛾科、透翅蛾、灯蛾亚科内的丰彩鹿蛾族与蜂蛾族的物种混淆，根据近年较被接受的亲缘关系假说，此亚科包含了分布於泛旧大陆的鹿蛾族以及仅分布在非洲之非洲鹿蛾族。

Just as morphology,it is an important phylogenetic signal and a significant factor of production isolation of avian.

其与鸟类的形态特征一样，都是鸟类的重要鉴别特征和生殖隔离的重要因素。

The phylogenetic relation of Ovine Babesia sp in Hebei, Liaoning province and at Lintan, Ningxian in Gansu province China, were analyzed by using 18srRNA sequence.

利用18S rRNA基因序列分析方法，对我国的河北、辽宁两省以及甘肃省的临潭和宁县四个不同地区羊的巴贝斯虫进行分子分类学研究。

Two phylogenetic trees was inferred based on 18srRNA sequence of Hebei, Liaoning province, Lintan, Ningxian in Gansu and the other species of Babesia and Theileria available in GenBank.

结果发现自河北、辽宁、临潭、宁县四个地区分离株建立的进化树上，临潭与宁县的虫株亲缘关系较近，同源性是91.4％；而辽宁与河北的同源性是95.8％。

Phylogenetic analysis suggests that the batrachian divergence occurred in the Middle Permian, rather than the late Carboniferous as recently estimated using molecular clocks18, 22, but the divergence with caecilians corresponds to the deep split between temnospondyls and lepospondyls, which is congruent with the molecular estimates.

谱系分析认为蛙形两栖类的分歧应发生于二叠纪中期，而不是石炭纪末。然而，与离片椎类和壳椎类这一意义深远的分歧密切相关的事件——蛙形两栖类与无足目的分歧的时间却与分子钟所估计的相符。

MtDNA D-loop sequences and cranial morphometrics were used to analyze the phylogenetic relationships of bharal ( Pseudois nayaur szechuanensis ) populations. The habitat preferences of bharal were also investigated in Helanshan, Ningxia.

本研究利用粒线体核酸 D-loop 序列分析及头骨形态分析岩羊四川亚种（ Pseudois nayaur szechuanensis ）各族群间的关系，并针对宁夏贺兰山岩羊族群分析其栖地偏好。

Eckenwalder Lab, Department of Botany is primarily dedicated to research in woody plants including biosystematics, chemotaxonomy, numerical taxonomy and morphometrics, paleobotany, and cladistics, accommodation of hybridization in phylogenetic analysis, biogeography, systematics and reproductive biology of convolvulaceae.
