51 Orchidaceous species discovered by way of investigation fall into 32 genuses with 41 sedentary plants, 7 adnascent plants and 3 saprophyte plants. Sedentary plants distribute in the communities are composed of panacea, fagaceae, rosaceae, ericaceae plants with life form geophytes.

在调查中出现的32属51种兰科植物中有41种地生兰、7种附生兰和3种腐生兰，地生兰中以兰属植物中的春兰、蕙兰分布最广，生长在松科、山毛榉科、蔷薇科、杜鹃科等构成的植物群落中，生活型为真地下芽植物。

The comparison of the genes with white-tailed deer and red deer PrP gene revealed that the nucleotide and its putative amino acid identities were 97.4%-98.2% and 97.7%-98.8%, respectively, it show the PrP genes of ruminant among the same family or different families are all conservative. The comparison of the genes with white-tailed deer and red deer PrP gene revealed there are five base substitutions produced amino acid mutation, e.g.

与同科不同亚科的马鹿和白尾鹿以及不同科的奶牛和绵羊朊蛋白基因序列比较，核苷酸序列和推导氨基酸序列同源性为97.3%～98.2%和97.7%～98.8%，说明朊蛋白基因在同科和不同科的反刍动物间是保守的。

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 results indicated the origin of Nipponia Nippon was comparative singleness. Homology of eighteen Cyt b gene sequences in mtDNA region among Threskiornithidae, Ciconiidae, Phoenicopteridae, Ardeidae and Gruidae were analyzed and their BSR and genetic distances calculated.

将朱鹮mtDNA Cyt b基因序列与鹮科、鹳科、红鹳科、鷺科、鶴科共18个个体的mtDNA Cyt b基因进行同源序列分析，并计算了mtDNA Cyt b基因的碱基相似率和遗传距离。

The investigation collected total about 1800 insect specimens, 130 species belonging to 51 families, 9 orders, 2 classes were identified. Among them, 105 species (40 families, 6 orders, 1 classes) were pests and 25 species (10 families, 5 orders, 2 classes) were natural enemies. In addition, two new record species, Caulophilus oryzae and Bruchus dentipes, were found.

通过调查采集，共查到出口木制品仓储昆虫群落害虫及天敌2目、23科、38种；出口草柳藤制品仓储害虫及天敌3目、22科、34种；出口皮革制品仓储害虫及天敌4目、24科、44种；出口羽绒制品仓储害虫及天敌4目、20科、35种；出口笔刷制品仓储害虫及天敌3目、26科、39种。

The forest is composed mainly of the families, Rubiaceae, Myrtaceae, Myristicaceae, Lauraceae and Euphorbiaceae, and dominated by tree species, Metadina trichotoma, Syzygium cathayense, Knema erratica and Paramichelia baillonii. In physiognomy, the forest is characterized by the trees with mesophyllous, entire and leathery leaves. Woody lianas are found dominant, but trees with buttresses and cauliflory are relatively few in the forest.

结果显示，勐养山地雨林主要由茜草科、桃金娘科、肉豆寇科、樟科、大戟科等植物种类组成，以黄棉木、华夏蒲桃、假广子及山桂花为乔木优势种；群落乔木层以中叶、全缘、革质、尾尖、常绿植物占优势，灌草层植物则以中叶、全缘、纸质叶植物为主；藤本植物中以木质藤本占优势，板根和茎花现象少见。

Using "neighbor-joining" of Mega 2.1 software reconstructed the molecular Phylogenetic Tree, the results indicated Labeoninae fishes might not be monophyletic population, C.molitorella and E.bicolor of Labeoninae assembled together with Cyprinus carpio and Carassius auratus firstly, and formed sister group, then assembled together with C.mrigala and L.rohita , which suggested that C.molitorella was genetically more relative to Cyprinidae than Labeoninae.

用Mega 2.1软件的NJ法构建分子系统树，结果表明：野鲮亚科鱼类没有形成单系类群，野鲮亚科的鲮、角鱼与鲤亚科的鲤、鲫形成姐妹群，然后再与野鲮亚科的麦鲮和露斯塔野鲮聚在一起，说明鲮与鲤亚科鱼类具有较近的亲缘关系。

The leaves were transported to the laboratory where densities of Phytoseiidae and of the most common mite families (e.g., Tetranychidae, Tenuipalpidae, Eriophyidae, Tydeidae, Winterschmidtiidae) were evaluated under a binocular microscope.

每次取样，每两个相同的样品需要收集10片叶子，采样得到的叶子将被送往实验室，在双筒显微镜下，可以对植缨螨科，以及最常见的螨科（如叶螨科，细须螨科，瘿螨科）的密度进行评估。

The Diplodactylini + padded carphodactylines were the sister group of pygopods + padless carphodactylines. We propose a new higher order classification of the Gekkota that reflect these results.

我们据此提出了壁虎类高级阶元新分类系统的建议，把Kluge (1987)的鳞脚虎科改订为三个科，即鳞脚虎科、絮趾虎科和刺尾虎科。
