Two sets of parsimony analyses were conducted, one using Bauera as the outgroup and the other using Cercidiphyllum-Liquidambar as outgroups.

数据矩阵中包括了马尾树科及其它&高等&金缕梅类各科，并分别利用Cunoniaceae科的Bauera属，&低等&金缕梅类植物连香树属和枫香树属作为外类群进行分支分析。

Until Sunday, only Betis Sevilla had been able to beat Deportivo in their first home match of a new season.

直到周日，只有贝蒂斯能够在赛季初拉科的第一个主场击败拉科。

In the strict consensus tree of the 484 trees, the monophyly of Betulaceae and Fagaceae is strongly supported.

胡桃科和桦木科的单系性都得到了分辨，虽然BS支持率不高。

The representative fanna is that from Qingyan, Guizhou province, southwestern China, dated as Late Anisian, composed of nearly 100 species assigned to more than 50 genera, belonging to 32 families of 5 subclasses in Bivalvia.

研究了二叠纪未生物大灭绝事件后双壳类的首次辐射，辐射的代表是贵州青岩地区中三叠世Anisian晚期的青岩生物群，共50余属100余种，归在5亚纲10目18超科32科。

Any of several widely distributed, chiefly marine fishes that are primarily of the families Blenniidae and Clinidae and have small, elongated, often scaleless bodies.

鳚鱼一种分布广，主要鳚科和热鳚科的海水鱼，有小而细长，常为无鳞的身体

The RAPD results illustrate that the phylogenetic relationship betweenBothriocephalid tapeworm parasitic in Grass carpCtenopharyngodon idellus(C.et V.and Common carp(Cyprinus carpio L.)from different regions ofChina is infraspecific with noticeable variance bwtween them.Thephylogenetic trees based on the 3 sequences analyses above are constructed,which show the following relationships:Bothriocephalid tapeworms fromGrass carp,Common carp and Luciobrama are found to be monophyletic,and are very close to Bothriocephalus opsariichthydis,but are divergent toanother monophyletic group comprising Bothriocephalid tapeworms fromZacco,Hemiculter and Leuciscus.On the basis of phylogenetic reconstruction,autapomorphic species conceptis used in species delimitation suitablefor determining four species in the present study:B.acheilognathi,B.opsariichthydis,and two other bothriocephalids parasitic respectively inHemiculter and Leuciscus.It is also deduced that the differentiation time ofBothriocephalid tapeworms parasitic in cyprinids is earlier than that of theirhosts,and the most recent specification happened about one million yearsago.Key words Bothriocephalid tapeworm Molecular Systematics

具体成果有：通过RAPD分析探明了我国不同地理分布的草、鲤鱼头槽绦虫的亲缘关系属于种下水平，并存在较高变异；通过基因合并分析重建头槽绦虫的系统发育关系，表明草鱼、鲤鱼及鯮鱼头槽绦虫是单系群，它们与马口鱼头槽绦虫亲缘关系较近，而与〓条、宽鳍鱲及雅罗鱼头槽绦虫构成的另一单系群亲缘关系较远；在此基础上，提出符合头槽绦虫种的界定的独征物种概念，据此确定鲤科鱼类寄生头槽绦虫的四个种：鱊头槽绦虫，马口鱼头槽绦虫，以及另两种分别寄生于〓条和雅罗鱼的头槽绦虫：根据上述研究推断鲤科鱼类寄生头槽绦虫的分化年代早于其宿主，最近的一次物种形成距今约一百万年左右。

Currently, InsectX has managed to generate SIKs of any insect taxa at family level or above and any known species of Braconidae in China at species level.

目前InsectX已支持定制国内昆虫科及以上分类单元、茧蜂科所有已知种在线进行二次检索表重构。

Brasenia quite differs from Nymphaea in floral organogenesis, so it shouldn t be treated in the same family with Nymphaea, and should be separated from Nymphaeaceae.

莼菜的花器官发生与睡莲的差别显著，作者认为它们不应置于同一科内，支持并重新提出将莼菜属从睡莲科中分离出来的观点。

The intergeneric phylogenetic trees of water lilies showed that Nelumbo and Ceratophyllum form a sister group, but with relatively high sequence divergence, supporting that place the two genera into two distinct families; and Brasenia and Cabomba form a sister group, with relatively low sequence divergence, supporting that the two genera were placed the same family Cabombaceae.

结果表明：莲属与金鱼藻属构成姐妹群，但序列分歧度较大，支持将两个属独立成科的观点；莼菜属与水盾草属构成姐妹群，且序列分歧度较小，支持现有的莼菜科处理。
