1Genetic consequences of postglacial colonization by the endemic Yarkand hare (Lepus yarkandensis) of the arid Tarim Basin显示文摘Orogenesis of the Qinghai-Tibetan Plateau,which occurred in a stepwise manner,contributed to the extreme aridity of the Tarim Basin,resulting in vulnerable and unstable ecosystems.Quaternary climatic oscillations may have affected the ecosystems and,consequently,the distributions and genetic structuring of the Tarim Basin's biota.We used nucleotide sequence data from 2 mitochondrial (mt) DNA genes (Cyt b and the D-loop) to test hypotheses associated with the matrilineal and demographical histories of the Tarim Basin's endemic Yarkand hare (Lepus yarkandensis).Range-wide sampling involving 20 populations and 224 individuals detected 126 haplotypes that clustered into 5 major lineages in both the phylogenetic tree and median-joining network.Populations from the northern and eastern Tarim Basin shared a similar history,as did those from the western and southern regions.Demographical analysis and genetic diversity estimations suggested that the western and southern regions might have served as glacial refugia for the Yarkand hare during Quaternary climatic oscillations.The distribution of the Yarkand hare,especially in the northern and eastern parts,probably represented 3 postglacial colonization events,dated to 0.21,0.090 and 0.054 MYA,which corresponded to known interglacial periods.Given the relatively complete geographic isolation between the eastern and southern populations,the Yarkand hare likely dispersed during postglacial periods from the southwest to the north,and then onward to the east.The absence of water likely forced the species into refugia,and this differed from other Pleistocene biogeographical drivers.The demographical and historical patterns have important implications for conservation.SHAN WenJuan LIU Jiang YU Li ROBERT W.

2外群选择对隧蜂科(膜翅目:蜜蜂总科)系统重建的影响(英文)显示文摘外群用于给树附根和推断祖先性状状态。通常,来自内群的姐妹群中的多个分类单元被共同选择作为外群。为了在经验上验证这一方法,我们采用了3种外群选择策略:姐妹群中的单一分类单元,姐妹群中的多个分类单元和连续姐妹群中的多个分类单元。以隧蜂科(膜翅目:蜜蜂总科)的系统发育重建为例,我们评估了这3种策略对树拓扑结构的影响,包括最大似然树、最大简约树和贝叶斯树。初步结果表明:相比其他两种策略,采用姐妹群中的多个分类单元作为外群更有利于系统发育重建得到现已被广泛认可的隧蜂科系统发育关系;相比最大似然法和贝叶斯法,虽然隧蜂科系统发育关系没有被很好地解决,但最大简约法在不同外群选择策略下得到了较为一致的拓扑结构。罗阿蓉 张彦周 乔慧捷 史卫峰 Robert W.

4A new species of the genus Raorchestes(Anura:Rhacophoridae) from Yunnan Province, China显示文摘DEAR EDITOR,A new bush frog species, Raorchestes cangyuanensis sp. nov., from Cangyuan, Yunnan Province, China, is described based on morphological and molecular analyses. It differs from all known congeners by a combination of the following characters: body size small, adult snout-vent length (SVL) 16.1–20.0 mm in males (n=3);tympanum indistinct;tips of all fingers and toes expanded into discs with circummarginal grooves;rudimentary webbing between toes;fingers and toes with lateral dermal fringes;inner and outer metacarpal tubercles present;heels meeting when limbs held at right angles to body;crotch with a distinct black patch;discs of fingers and toes orange;male with external single subgular vocal sac and reddish nuptial pad at the base of first finger.Yun-He Wu Chatmongkon Suwannapoom Kai Xu Jin-Min Chen Jie-Qiong Jin Hong-Man Chen Robert W.

6基于分子系统学的可疑瑟姬小蜂分类修订及姬小蜂亚科盾纵沟的演化分析(英文)显示文摘姬小蜂为寄生蜂的演化研究提供了很好的材料。在姬小蜂分类中,盾纵沟是一个重要性状,曾被用来区分亚科、族、属及种。非同源性相似形态特征的存在使得物种准确鉴定存在困难。从盾纵沟形状上,可疑瑟姬小蜂Cirrospilus ambiguus和双斑潜蝇姬小蜂Diglyphus bimaculatus应介于瑟姬小蜂属Cirrospilus和潜蝇姬小蜂属Diglyphus之间。确定这两种姬小蜂的系统发育位置将有助于分析盾纵沟的演化模式。本文用贝叶斯方法分析了线粒体COⅠ部分序列、核糖体ITS1序列及核糖体28S D2区部分序列等3个基因序列,结果显示可疑瑟姬小蜂应被移到潜蝇姬小蜂属中;研究结果支持潜蝇姬小蜂属是单系,而不支持瑟姬小蜂属是单系。结合28S D2区部分序列的贝叶斯分析结果,分析了在姬小蜂亚科中盾纵沟的演化模式。结果显示,完整且延伸到中胸背板后缘的盾纵沟代表其原始类型;完整且延伸到三角片的盾纵沟类型分别出现在5个独立的枝上,代表了该特征5次独立的演化;不完整的盾纵沟类型出现在4个独立的枝上,表明该类型独立演化了4次。沙忠利 朱朝东 Robert W.

7急性缺血性卒中动脉内导管介入治疗培训指南 介入放射学学会特别写作组的声明显示文摘在美国,卒中是引起成年人残疾的首位原因,也是人口死亡的第三大原因,已成为一个重要的公共健康问题。卒中每年危及近80万人的健康,其治疗费用位居所有疾病之首。10%的卒中患者在发病后1个月内死亡,约1乃的卒中患者遗留严重残疾并在发病后6个月内死亡。这些数据提示,卒中的死亡率高于癌症。J.J.

9Factors affecting mito-nuclear codon usage interactions in the OXPHOS system of Drosophila melanogaster显示文摘Codon usage bias varies considerably among genomes and even within the genes of the same genome.In eukaryotic organisms,energy production in the form of oxidative phosphorylation(OXPHOS) is the only process under control of both nuclear and mitochondrial ge-nomes.Although factors affecting codon usage in a single genome have been studied,this has not occurred when both interactional ge-nomes are involved.Consequently,we investigated whether or not other factors influence codon usage of coevolved genes.We used Drosophila melanogaster as a model organism.Our χ2 test on the number of codons of nuclear and mitochondrial genes involved in the OXPHOS system was significantly different(χ2 = 7945.16,P < 0.01).A plot of effective number of codons against GC3s content of nu-clear genes showed that few genes lie on the expected curve,indicating that codon usage was random.Correspondence analysis indicated a significant correlation between axis 1 and codon adaptation index(R = 0.947,P < 0.01) in every nuclear gene sequence.Thus,codon usage bias of nuclear genes appeared to be affected by translational selection.Correlation between axis 1 coordinates and GC content(R = 0.814,P < 0.01) indicated that the codon usage of nuclear genes was also affected by GC composition.Analysis of mitochondrial genes did not reveal a significant correlation between axis 1 and any parameter.Statistical analyses indicated that codon usages of both nDNA and mtDNA were subjected to context-dependent mutations.Zheng Sun Liang Ma Robert W.

16Molecular phylogeny found the distribution of Bungarus candidus in China(Squamata: Elapidae)显示文摘Based on molecular phylogeny of the Chinese white cross-band krait, Bungarus multicinctus, several individuals from southwestern and southern China were found to be nested within putative species B. candidus(Linnaeus, 1758) with high support values. Morphological examination also indicated these specimens were identical to B. candidus. We concluded that the Chinese white cross-band krait, previously identified as B. multicinctus in southwest and south China, should be recognized as B. candidus, a new record in China, and B. m. wanghaoti should be invalid. B. multicinctus is recurrently limited to southern China within China.Yulin Xie Ping Wang Guanghui Zhong Fei Zhu Qin Liu Jing Che Lei Shi Robert W.

17Conserved sequences identify the closest living relatives of primates显示文摘Elucidating the closest living relatives of extant primates is essential for fully understanding important biological processes related to the genomic and phenotypic evolution of primates, especially of humans. However, the phylogenetic placement of these primate relatives remains controversial, with three primary hypotheses currently espoused based on morphological and molecular evidence. In the present study, we used two algorithms to analyze differently partitioned genomic datasets consisting of 45.4 Mb of conserved non-coding elements and 393 kb of concatenated coding sequences to test these hypotheses. We assessed different genomic histories and compared with other molecular studies found solid support for colugos being the closest living relatives of primates. Our phylogeny showed Cercopithecinae to have low levels of nucleotide divergence, especially for Papionini, and gibbons to have a high rate of divergence. The MCMCtree comprehensively updated divergence dates of early evolution of Primatomorpha and Primates.Mei-Ling Zhang Ming-Li Li Adeola Oluwakemi Ayoola Robert W.

18A new species of the genus Xenophrys(Anura:Megophryidae) from northern Thailand显示文摘DEAR EDITOR,Species of Xenophrys are conserved morphologically and live primarily in forests. In Thailand, the genus harbors many cryptic species. Herein we report the collection of specimens from Doi Inthanon, Chiang Mai Province, northern Thailand, which were identified previously as X. minor. Molecular and morphological analyses find that these specimens differ significantly from other known congeners, and therefore we describe a new species. Further, our phylogenetic analyses indicate that X. latidactyla is a junior synonym of X. palpebralespinosa.Yun-He Wu Chatmongkon Suwannapoom Nikolay A.
