查询词典 Araneoidea

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。

In addition, the reconstructed phylogenetic tree based on cDNA and DNA sequences encoding C-terminal non-repetitive region of MaSp1 (Major ampullate spidroin-1) also showed that Deinopoidea and Araneoidea are not sister groups.

另外，依据编码大壶状腺丝蛋白-1(MaSp1)C末端非重复氨基酸序列区段的核酸序列重建的系统发生树也证实圆网蛛类并非单系发生。

This finding well supports that the orb-web similarities between Deinopoidea and Araneoidea are more likely the result of convergent rather than homologous evolution.

重建的系统发生树表明：园蛛总科和妖面蛛总科蜘蛛不是姊妹群，从而支持这两个类群的圆网是平行演化而非同源演化的观点。

The phyolgenetic trees of Araneoidea were reconstructed with NJ, MP and ML methods.

用NJ法、MP法、以及ML法重建了分子系统树。

Web-spinning spiders, whose habitats or biology are diverse, construct many types of aerial webs. Most species of spiders belonging to Deinopoidea and Araneoidea use orb-webs to capture prey.

蜘蛛目中的织网蜘蛛由于栖息环境、捕食方式等方面的差异而织不同类型的蛛网，其中只有妖面蛛总科和园蛛总科两个类群蜘蛛织圆网。

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.

但关于妖面蛛总科和园蛛总科间系统发生关系，即圆网蛛类是否为单系起源，换言之，圆网究竟是经历一次进化还是多次进化，多年来始终是悬而未决的蛛形学难题之一。

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.

本文首先测定了包括复杂生殖器类中妖面蛛总科、园蛛总科和非圆网蛛类等3个类群在内的9科10种蜘蛛线粒体12S rDNA、16S rDNA及核18S rDNA、28S rDNA等4个基因片段序列，并基于4个基因序列的整合数据，分别通过邻接法、最大简约法、最大似然法和贝叶斯法分析，对园蛛总科和妖面蛛总科蜘蛛之间的分子系统关系进行了探讨。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
