Species diversity of the subgenus Amiota (s. str.) Loew, 1862 (Diptera, Drosophilidae) in southern China

A total of 38 Amiota (s. str.) species (about 40% of the world total) are reported from southern China, with descriptions of 23 new species, i.e. sinuata species-group: aculeata Chen and Aotsuka, sp. nov., subsinuata Chen and Aotsuka, sp. nov., xishuangbanna Chen and Aotsuka, sp. nov.; basdeni species-group: brevipartita Chen and Gao, sp. nov., curvispina Chen and Gao, sp. nov., lipingae Chen and Gao, sp. nov., huae Chen and Gao, sp. nov., longispina Chen and Gao, sp. nov.; taurusata species-group: asymmetrica Chen and Takamori, sp. nov.; femorata Chen and Takamori, sp. nov., yixiangensis Chen and Takamori, sp. nov.; alboguttata species-group: ailaoshanensis Chen and Watabe, sp. nov., arcuata Chen and Watabe, sp. nov., dehiscentia Chen and Watabe, sp. nov., jizushanensis Chen and Watabe, sp. nov., latitabula Chen and Watabe, sp. nov., luguhuensis Chen and Watabe, sp. nov., nozawai Chen and Watabe, sp. nov., paraspinata Chen and Watabe, sp. nov., shangrila Chen and Watabe, sp. nov.; and ungrouped: fuscicata Chen and Zhang, sp. nov., wangi Chen and Zhang, sp. nov., wuyishanensis Chen and Zhang, sp. nov. A key to all species from southern China is provided. The Amiota fauna of southern China at the species-group level is compared with that of six geographic regions. The subgenus Amiota is assumed to have originated and produced many species-groups in the Oriental region of East Asia, and then the basdeni, alboguttata and rufescens species-groups might have spread to Europe and North-Central America throughout the Palearctic region of East Asia and both the apodemata, sinuata and nagatai species-groups to tropical regions of South-East Asia.

瘦尾细额溞Oxyurella tenuicaudis(Sars,1862)的若干生物学特征

瘦尾细额溞是一种出现数量极其稀少的枝角类。关于它的生物学特征尚未见诸文献。本文测量了一次采自云南永胜一池塘的本种300个两性个体的体长和怀卵量,就其幼体与成体的数量、体长与怀卵量、雄性以及性比等问题探讨了种群的生物学状况。 详细观察比较了这个种的重要分类特征——雌体后腹部,并描述了变异范围。对卵鞍和雄体也作了描述。

Permanent Genetic Resources added to Molecular Ecology Resources Database 1 May 2009-31 July 2009

This article documents the addition of 512 microsatellite marker loci and nine pairs of Single Nucleotide Polymorphism (SNP) sequencing primers to the Molecular Ecology Resources Database. Loci were developed for the following species: Alcippe morrisonia morrisonia, Bashania fangiana, Bashania fargesii, Chaetodon vagabundus, Colletes floralis, Coluber constrictor flaviventris, Coptotermes gestroi, Crotophaga major, Cyprinella lutrensis, Danaus plexippus, Fagus grandifolia, Falco tinnunculus, Fletcherimyia fletcheri, Hydrilla verticillata, Laterallus jamaicensis coturniculus, Leavenworthia alabamica, Marmosops incanus, Miichthys miiuy, Nasua nasua, Noturus exilis, Odontesthes bonariensis, Quadrula fragosa, Pinctada maxima, Pseudaletia separata, Pseudoperonospora cubensis, Podocarpus elatus, Portunus trituberculatus, Rhagoletis cerasi, Rhinella schneideri, Sarracenia alata, Skeletonema marinoi, Sminthurus viridis, Syngnathus abaster, Uroteuthis (Photololigo) chinensis, Verticillium dahliae, Wasmannia auropunctata, and Zygochlamys patagonica. These loci were cross-tested on the following species: Chaetodon baronessa, Falco columbarius, Falco eleonorae, Falco naumanni, Falco peregrinus, Falco subbuteo, Didelphis aurita, Gracilinanus microtarsus, Marmosops paulensis, Monodelphis Americana, Odontesthes hatcheri, Podocarpus grayi, Podocarpus lawrencei, Podocarpus smithii, Portunus pelagicus, Syngnathus acus, Syngnathus typhle,Uroteuthis (Photololigo) edulis, Uroteuthis (Photololigo) duvauceli and Verticillium albo-atrum. This article also documents the addition of nine sequencing primer pairs and sixteen allele specific primers or probes for Oncorhynchus mykiss and Oncorhynchus tshawytscha; these primers and assays were cross-tested in both species.

一种新蛋白源──青海钩虾（Gammarus suifunensis,Ueno,1940）营养价值的初步研究

对青海钩虾的营养价值进行了初步的研究。首先分析三种不同品级的青海钩虾，一般营养成分及氨基酸含量，并同两种鱼粉比较；第二，养鸡试验的结果表明，钩虾组在平均增量和总增重量等方面都优于鱼粉；第三，真鲷Pagrosomusmajor（Temminck＆Schlegel）的实验是按照逐次降低钩虾的含量的方法，分为4组。Ⅰ．钩虾：鱼粉＝6：4，Ⅱ．钧虾：鱼粉＝4：6，Ⅲ．钩虾：鱼粉＝2：8，Ⅳ．钩虾：鱼粉＝0：10。实验结果显示在其鲷的成活率、体长平均增长率、增重率和饲料系数等方面，含钩虾组较无钩虾（Ⅳ）为佳，而Ⅱ组具有最好的促增重效果和最经济的特点。最后，根据上述分析和实验结果，作者认为青海钩虾是一种可以代替鱼粉的新蛋白源，值得开发利用和推广。
