<正>蓝额地鸲Cinclidium frontale为雀形目鸫科地鸲属鸟类(郑光美,2011),曾记为鹟科鸫亚科长脚鸲属蓝额长脚地鸲Callene frontale(张俊范,郑作新,1963)。国外见于印度、尼泊尔、不丹、老挝、越南(郑作新等,1995)。在国内的分布,马敬能等(2000)表明四川亚种Cinclidium f.orientale记录于四川石棉大渡河、云南南部,指名亚种C.f.frontale可能见于西藏东南部;郑光美     

(行鸟)形目12种鸟类线粒体细胞色素b基因序列差异及其系统发育关系

采用PCR直接测序方法首次对Hang形目(Charadriiformes)12种鸟类：蒙古沙Hang(Charadrius mongolus)、环颈Hang(Charadrius alexandrinus)、大杓鹬(Numenius madagascariensis)、白腰杓鹬(Numenius arquata)、中杓鹬（Numenius phaeo-pus）、红脚鹬（Trina totanus）、林鹬（Trina alareola）、翘嘴鹬（Xenus cineres）、翻石鹬（Arenaria interpres）、大滨鹬（Calidris teruarostris)、反嘴鹬（Recurvirostra avosetts)和砺鹬（Haematopus ostralensis)线粒体cyt b基因全序列进行测定,并以白鹳（Ciconia ciconia)的同序列作为外群杓建系统发生树。经比对,Hang形目12种鸟类线粒体cyt b基因全序列均包括1143bp,序列间未见有插入和缺失,共有381个变异位点,种间序列差异值为5．16％—16．01％。重建的系统树将Hang形目12种鸟类分为2个支系：第1支系包括红脚鹬、林鹬、翻石鹬、大滨鹬、翘嘴鹬、中杓鹬、大杓鹬和白腰杓鹬,其中红脚鹬、林鹬、翻石鹬、大滨鹬、翘嘴鹬聚为一支,中杓鹬、大杓鹬和白腰杓鹬聚为另一支;第2支系包括蒙古沙Hang、环颈Hang、反嘴鹬和硕鹬,其中反嘴鹬与砺鹬互为姐妹群,然后再与Hang属的两个种蒙古沙Jamg和环Hang组成的姐妹群构成并系群。分子证据提示：第1支系中各属问及种间的系统关系与形态学研究结果相吻合;第2支系中的反嘴鹬与Hang鹬之间的亲缘关系较近,两者聚为姐妹群,提示将这两个类群合并为一个亚科——反嘴葫亚科更为合理,与码亚科共同组成Hang科,与核型研究结果和Sibley在新分类体系中将码科分为反嘴鹬亚科和Hang亚科、反嘴鹬族和砺鹬族属于反嘴鹬亚科的观点相一致。     

常见笼鸟的饲养

笼鸟是指那些博得人们欢心的、羽色艳丽、姿态优美、鸣声悦耳的小鸟,由家庭用小笼饲养、繁殖而得名;它包括雀形目和鹦形目的一些种类。常见的有百灵、画眉、点颏、八哥、鹩鸽、交嘴雀、蜡嘴雀、金丝雀、虎皮鹦鹉、十姐妹、灰文鸟等。笼鸟按地区饲养习惯来说,可分为南方种,如乌鸫、八色鸫、白头鹎、鹊鸲;北方种,如百灵、凤头百灵、黄雀、太平鸟、沼泽山雀;还有原产于国外的品种,如金丝雀、虎皮鹦鹉、锦花鸟、灰文鸟、白文鸟、五彩文鸟。笼鸟依食性则可分为食谷鸟、食虫鸟、杂食鸟、食肉鸟四种类型。笼鸟的种类很多,如何科学地饲养管理,国内还很少有人进行专门研究。一些笼鸟饲养者常因缺乏饲

王朗自然保护区鸟类调查报告

本文报道了王朗自然保护区的鸟类总计为139种另5亚种,分隶于12目32科(4亚科)。其中鸟76,夏候鸟52,冬候鸟6和旅鸟10种与亚种;棕头歌鸲是迄今国内采到的唯一标本。分析表明,以栖息针阔叶混交林的鸟类最多,占保护区鸟类总数的92.4%;全部优势种、89.5%的特种和87.5%的国家重点保护鸟类均见于这一生境。从繁殖鸟的区系从属关系进行分析,保护区内以古北鸟类为主,占60.6%,东洋界鸟类仅占29.2%。     

从线粒体细胞色素b探讨长臀鲃属三个种分类与进化的关系

本研究测定了长臀属(MystacoleucusG櫣ｎｔｈｅｒ）中的３个种 :月斑长臀(M.chilopterusFowler)、长臀[M.marginatus(CuvieretValenciennes)]和细尾长臀(M.lepturusHuang)共22个个体的线粒体细胞色素b部分基因片段 ,其序列为408bp,并选用亚科(Acheilognathinae)中华(RhodeussinensisG櫣ｎｔｈｅｒ）及亚科（Ｂａｒｂｉｎａｅ）中的云南倒刺(Spinibarbus.denticulatusyunnanensisTsu)作为外群。结果表明 :细尾长臀与月斑长臀、长臀间存在遗传分化 ,分化程度与鲤科其它鱼类相似 ;而月斑长臀和长臀却无法分开。结果提示 ,月斑长臀和长臀很可能为同一个种。此外 ,长臀属与云南倒刺的亲缘关系较近 ,表明有争议的长臀属归入亚科是合理的。     

燕雀亚科鸟类的贝叶斯系统发生:非洲鹂雀的分类地位及朱雀属的进化与异质起源

鹂雀(Linurgus olivaceus)是非洲热带森林中一种独特的鸣禽,为鹂雀属(Linurgus)的惟一物种。在已有的研究中,通过对鹂雀和雀形目现存鸟类中每个科及亚科至少一个物种的线粒体DNA序列测定,分析了鹂雀与其它现存雀形目鸟类的系统发生关系;在遗传上,对鹂雀与金丝雀、金翅雀及燕雀亚科其它鸟类亦有比较研究。本研究共使用了燕雀亚科83种鸟类,重点对该亚科的系统发生进行了修订。使用贝叶斯法构建了系统发生树,结果表明:鹂雀属于燕雀亚科,系统发生树中聚在金翅雀族(Carduelini),与金丝雀属(Serinus)、金翅雀属(Carduelis)及交嘴雀属(Loxia)的种类形成一组;在系统发生中,鹂雀可能是一个基部物种,它同金丝雀属和金翅雀属鸟类一同进化并分歧出来。在本研究中未能涉及的一些已灭绝种类,可能与鹂雀有着较近的遗传学关系。另一方面,研究也表明锡嘴雀(Coccotharustes coccothraustes)肯定包括在欧亚蜡嘴雀(蜡嘴雀属Eophona和拟蜡嘴雀属Mycerobas)中,美洲的朱雀(Carpodacus)可能是从亚洲种类分歧出来并经过进化辐射形成。

A molecular phylogenetic analysis of the "true thrushes" (Aves: Turdinae)

The true thrushes (Passeriformes: Muscicapidae, subfamily Turdinae) are a speciose and widespread avian lineage presumed to be of Old World origin. Phylogenetic relationships within this assemblage were investigated using mitochondrial DNA (mtDNA) sequence data that included the cytochrome b and ND2 genes. Our ingroup sampling included 54 species representing 17 of 20 putative turdine genera. Phylogenetic trees derived via maximum parsimony and maximum likelihood were largely congruent. Most of the Turdine taxa sampled can be placed into one of six well supported clades. Our data indicate a polyphyletic Zoothera which can be divided into at least two (Afro-Asian and Austral-Asian) main clades. The genus Turdus, as presently recognized, is paraphyletic but forms a well supported clade with the addition of three mostly monotypic genera (Platycichla, Nesocichla, and Cichlherminia). We identify an exclusively New World clade that includes a monophyletic Catharus, Hylocichla, Cichlopsis, Entomodestes, Ridgwayia, and Ixoreus. Members of the morphologically and behaviorally distinct genera Sialia, Myadestes, and Neocossyphus unexpectedly form a basal clade. Using multiple outgroup choices, we show that this group is distantly related, but unequivocally the sister group to the remaining Turdines sampled. The Turdinae appear to be a relatively old songbird lineage, originating in the mid to late Miocene. If the Turdinae are indeed Old World in origin, our data indicate a minimum of three separate invasions of the New World.     

基于线粒体Cyt b基因的线蛱蝶亚科的系统发育

基于线粒体Cytb基因部分序列,以波蛱蝶为外群,采用邻接法、最大简约法和贝叶斯法分别构建了中国线蛱蝶亚科10属25种蝶类的系统发育树,探讨了各主要类群间的系统发育关系。其结果表明,所有线蛱蝶亚科聚为两大枝:第一枝包括环蛱蝶属、菲蛱蝶属、蟠蛱蝶属和缕蛱蝶属,其中缕蛱蝶属与环蛱蝶族亲缘关系较近;第二枝包括丽蛱蝶属、穆蛱蝶属、线蛱蝶属、带蛱蝶属、律蛱蝶属和翠蛱蝶属,其中线蛱蝶属为非单系群,翠蛱蝶属和律蛱蝶属则为单系发生,并构成姐妹群。     

Nuclear and mitochondrial DNA evidence of polyphyly in the avian superfamily Muscicapoidea

Nucleotide sequences of the nuclear c-mos gene and the mitochondrial cytochrome b and ND2 genes were used to assess the monophyly of Sibley and Monroe's [Distribution and Taxonomy of Birds of the World, Yale University Press, New Haven, 1990] Muscicapoidea superfamily. The relationships and monophyly of major lineages within the superfamily, as well as genera membership in major lineages was also assessed. Analyses suggest that Bombycillidae is not a part of Muscicapoidea, and there is strongly supported evidence to suggest that Turdinae is not part of the Muscicapidae, but is instead sister to a Sturnidae+Cinclidae clade. This clade is in turn sister to Muscicapidae (Muscicapini+Saxicolini). Of the 49 Turdinae and Muscicapidae genera that we included in our analyses, 10 (20%) are shown to be misclassified to subfamily or tribe. Our results place one current Saxicolini genus in Turdinae, two Saxicolini genera in Muscicapini, and five Turdinae and two Muscicapini genera in Saxicolini; these relationships are supported with 100% Bayesian support. Our analyses suggest that c-mos was only marginally useful in resolving these "deep" phylogenetic relationships.     

A molecular phylogenetic analysis of the family Rhacophoridae with an emphasis on the Asian and African genera

Using characters from mitochondrial DNA to construct maximum parsimony and maximum likelihood trees, we performed a phylogenetic analysis on representative species of 14 genera: 12 that belong to the treefrog family Rhacophoridae and two, Amolops and Rana, that are not rhacophorids. Our results support a phylogenetic hypothesis that depicts a monophyletic family Rhacophoridae. In this family, the Malagasy genera Aglyptodactylus, Boophis, Mantella, and Mantidactylus form a well-supported sister clade to all other rhacophorid genera, and Mantella is the sister taxon to Mantidactylus. Within the Asian/African genera, the genus Buergeria forms a well-supported clade of four species. The genera, except for Chirixalus, are generally monophyletic. An exception to this is that Polypedates dennysii clusters with species of Rhacophorus, suggesting that the taxonomy of the rhacophorids should be revised to reflect this relationship. Chirixalus is not monophyletic. Unexpectedly, there is strong support for Chirixalus doriae from Southeast Asia forming a clade with species of the African genus Chiromantis, suggesting that Chiromantis dispersed to Africa from Asia. Also, there is strong support for the sister taxon relationship of Chirixalus eiffingeri and Chirixalus idiootocus apart from other congeners.     

新疆食蝗鸟类的初步研究

新疆是我国主要畜牧业生产基地之一,全区拥有90余万平方公里的天然草场,约占全国草场面积四分之一,仅次于内蒙,居全国第二位。但这富饶辽阔的草原,蝗害严重,蝗虫种类达150多种。新中国成立后,党和人民政府十分重视治蝗工作,据新疆治蝗灭鼠指挥部的资料,1953—1984年,全区累计治蝗面积达5000多万亩,其中飞机治蝗1460多万亩,为发展新疆畜牧业生产起到了十分重要的作用。虽然如此,由于单一化学防治,人们已经看到生态学上的弊端及伴随而来的严重后果,为此,哈巴河、昌吉等县已把草原养鸡和惊鸟的招引作为防治蝗害的重要措施。     

An evaluation of the monophyly of Massarina based on ribosomal DNA sequences

The monophyletic status of the genus Massarina was evaluated on the basis of phylogenetic analysis of the partial small subunit gene (SSU), internal transcribed spacers (ITS 1 & 2), and 5.8S gene sequences of the ribosomal DNA. Species of Massarina used in the study clustered into two distinct clades with high bootstrap support in trees generated from maximum parsimony, weighted parsimony, maximum likelihood, and neighbor-joining analyses. The hypothesis that Massarina species belong to a phylogenetically monophyletic group is rejected. Species with narrowly fusiform ascospores form a monophyletic clade with Lophiostoma, a genus highly similar in morphology. The five species currently accepted in Massarina with such spore morphology are here transferred into the genus Lophiostoma. Massarina species with broadly fusiform to ellipsoidal ascospores are retained as Massarina s. str., lectotypified by M. eburnea. Massarina walkeri is presently excluded from both Massarina and Lophiostoma. The transfer of M. papulosa to a new genus Oletheriostrigula is verified.     

Molecular phylogeny of Eastern Pacific porcelain crabs, genera Petrolisthes and Pachycheles, based on the mtDNA 16S rDNA sequence: phylogeographic and systematic implications

Porcelain crabs, genera Petrolisthes and Pachycheles, are diverse and abundant members of the eastern Pacific near-shore decapod crustacean community. Morphology-based taxonomic analyses of these crabs have determined groupings of affiliated species, but phylogenetic relationships remain unknown. We used sequence data from the mitochondrial 16S rRNA gene of 46 species of eastern Pacific porcelain crabs to perform phylogenetic analyses by distance and parsimony methods. Our results are used to compare the taxonomic significance of morphological and molecular characters, to examine sequence divergence rates of crab 16S rRNA genes, and to analyze the phylogeographic history of these crabs. Our phylogenetic trees indicate that the genus Petrolisthes is divided into two main clades, reflecting morphological features. One clade contains primarily tropical species, and the other contains species from throughout the eastern Pacific, as well as species in the genera Allopetrolisthes and Liopetrolisthes. Phylogenetic trees of Pachycheles suggest an antitropical distribution; north and south temperate species form one clade and tropical species form a second clade. Sequence divergence rates of the 16S rRNA gene from three pairs of geminate species can be used to date divergence times, and we discuss porcelain crab phylogeographic patterns in relation to paleogeographic events.     

基于线粒体基因cyt b的鹟亚科部分鸟类系统发育

采用分子系统学方法对鹟亚科(Muscicapinae)6属31种鸟类的cytb基因序列992bp进行系统发生分析。以荒漠伯劳(Lanius isabellinus)和发冠卷尾(Dicrurus hottentottus)为外群,采用贝叶斯法(Bayesian,BI)、最大似然法(Maximum-likelihood,ML)和最大简约法(Maximumparsimony,MP)分别构建鹟亚科的系统发育树。结果支持:寿带属(Terpsiphone)、扇尾鹟属(Rhipidura)与方尾鹟属(Culicicapa)可从鹟亚科中移出,其中寿带属归入王鹟科(Monarchidae),扇尾鹟属与方尾属归入扇尾鹟科(Rhipiduridae);鹟属(Muscicapa)、仙鹟属(Niltava)为单系发生,并聚为姐妹群,亲缘关系较近;姬鹟属(Ficedula)并非单系发生,白眉姬鹟(Ficedulazanthopygia)在3种系统发生树中的位置差别较大,研究结果未能确定其分类地位;铜蓝(Muscicapa thalassina)与白腹蓝(Cyanoptila cyanomelana)亲缘关系较近,前者应从属中移出,后者应从姬属移出,共同归入仙属或列为仙属的姐妹属。上述结论解决了亚科部分有争议属、种间的进化关系,为亚科分类系统提供了DNA水平证据。
