1Matrilineal History of the Rana longicrus Species Group(Rana,Ranidae,Anura) and the Description of a New Species from Hunan,southern China显示文摘Fieldwork in Jiemuxi National Nature Reserve,Hunan,China,discovered morphologically indistinguishable groups of brown frogs that bred at different,exclusive times of the year.A principal components analysis of morphometric data,molecular analyses,and the exclusive breeding season suggested the occurrence of two species.The population that breeds during the winter was found to be an undescribed species and was subsequently described as Rana jiemuxiensis sp.nov.The new cryptic species can be identified from its congeners at the same locality by having a different breeding season and a divergent DNA barcode.Six major lineages of brown frogs were resolved with high nodal support.Rana japonica,R.chaochiaoensis,R.omeimontis,and R.jiemuxiensis have independent maternal lineages.Rana hanlunica and R.maoershanensis have essentially identical maternal lineages and they appear to represent the same species.The validity of the species R.longicrus,R.zhenhaiensis,and R.culaiensis and their genealogical relationships are not resolved and deserve further study.The genealogy indicates that sympatric cryptic lineages probably widely exist in the R.longicrus group.This highlights the importance of future more fine-scaled samplings and the inclusion of nuclear genes.Fang YAN Ke JIANG Hongman CHEN Ping FANG Jieqiong JIN Yi LI Shaoneng WANG Robert W.MURPHY Jing CHE Yaping ZHANG 2011Asian Herpetological Research2011,2,2:8
2How many species of Apodemus and Rattus occur in China? A survey based on mitochondrial cyt b and morphological analyses显示文摘Apodemus(mice) and Rattus(rats) are the top rodent reservoirs for zoonoses in China, yet little is known about their diversity. We reexamined the alpha diversity of these two genera based on a new collection of specimens from China and their cyt b sequences in Gen Bank. We also tested whether species could be identified using external and craniodental measurements exclusively. Measurements from 147 specimens of Apodemus and 233 specimens of Rattus were used for morphological comparisons. We analysed 74 cyt b sequences of Apodemus and 100 cyt b sequences of Rattus to facilitate phylogenetic estimations. Results demonstrated that nine species of Apodemus and seven species of Rattus, plus a new subspecies of Rattus nitidus, are distributed in China. Principal component analysis using external and craniodental measurements revealed that measurements alone could not separate the recognized species. The occurrence of Rattus pyctoris in China remains uncertain.Shao-Ying Liu Kai He Shun-De Chen Wei Jin Robert W.Murphy Ming-Kun Tang Rui Liao Feng-Jun Li 2018Zoological Research2018,39,5:7
3鼩鼹亚科(Talpidae:Uropsilinae)一新种显示文摘2006年至2009年,在四川西南地区开展小型兽类区系调查时,在普格县、美姑县、泸定县、九龙县采获了11号鼩鼹类标本。其外形和头骨形态与其他鼩鼹类一致,但牙齿数量和齿式与已知鼩鼹类不同。这批标本上、下颌牙齿均为9枚,齿式为i2/2,c1/1,pm3/3,m3/3=36,与少齿鼩鼹上颌9枚、下颌8枚(齿式:i2/1,c1/1,pm3/3,m3/3=34)不同,也不同于长吻鼩鼹与贡山鼩鼹(齿式:i2/1,c1/1,pm4/4,m3/3=38)及峨眉鼩鼹(齿式:i2/2,c1/1,pm4/3,m3/3=38)上颌10枚、下颌9枚,而不能归类于现有任何已知鼩鼹类物种。通过线粒体细胞色素b基因构建的系统发育关系显示未归类标本形成一单系群,且与峨眉鼩鼹关系最近,构成姊妹关系。为此,我们认为采自于四川普格县、美姑县、泸定县、九龙县的鼩鼹类标本为鼩鼹亚科一新物种。根据新种上、下颌牙齿数量相等命名为等齿鼩鼹(Uropsilus aequodonenia)。刘洋 刘少英 孙治宇 郭鹏 范振鑫 Robert W.Murphy 2013兽类学报2013,33,2:7
4Phylogenetic Relationships of the Genus Paramesotriton(Caudata: Salamandridae) with the Description of a New Species from Qixiling Nature Reserve, Jiangxi, Southeastern China and a Key to the species显示文摘The matrilineal genealogy of the genus Paramesotriton is hypothesized based on DNA sequences from mitochondrial NADH subunit two(ND2) and its flanking tRNAs(tRNATrp and a partial tRNAAla). The genealogy identifies a highly divergent, unnamed lineage from Qixiling Nature Reserve, Jiangxi, China and places it as the sister taxon of P. chinensis. The newly discovered population differs from other congeners by several features of external morphology including having large clusters of dark brown conical warts on the dorsum of the head, lateral surface of the body and dorsolateral ridges. Its intermittent dorsal vertebral ridge is the same color as other parts of the dorsum and tail narrows gradually from the base to the tip. Further, the new population differs from all congeners by an uncorrected P-distance of more than 9.38% in ND2. Consequently, we describe the new species of Asian warty newt(Salamandridae) as Paramesotriton qixilingensis sp. nov.Zhiyong YUAN Haipeng ZHAO Ke JIANG Mian HOU Lizhong HE Robert W.MURPHY Jing CHE 2014Asian Herpetological Research2014,5,2:7
5Reproductive Behavior and Underwater Calls in the Emei Mustache Toad,Leptobrachium boringii显示文摘The Emei mustache toad,Leptobrachium boringii(Megophryidae),is terrestrial but breeds in permanent streams.Primarily,it has a polygynous mating system and polyandry also occurs.The species vigorously defends submerged nest sites.We report on a reproductive study at Mt.Emei,western China conducted in 2004,2006,2007,2009,and 2011 during the breeding season.Males produce both advertisement and courtship calls underwater,and the latter differs from the former in having an additional trill-like last note of low intensity.Females might determine the oviposition location and hence the egg mass location.A low,submissive posture can be adopted by the male to avoid being attacked by other males.When fi ghting,the maxillary nuptial spines are employed as weapons,and males hold their opponents on their spines with the forelimbs that enlarge during the breeding season.Male body size and the quantity of fi ght wounds on its ventral side are positively correlated.Satellite male mating might exist in L.boringii.Additionally,underwater calls from another population of this species and a population of L.leishanense generally are similar to those of the population from Mt.Emei.Yuchi ZHENG Dingqi RAO Robert W.MURPHY Xiaomao ZENG 2011Asian Herpetological Research2011,2,4:5
6基于18S基因序列的姬小蜂分子系统发育(英文)显示文摘本文基于18S rDNA部分序列,用MP和Baysian方法研究了姬小蜂科的系统发育,对姬小蜂科的单系性及其与其它小蜂科间的关系进行了讨论。姬小蜂亚科、灿姬小蜂亚科和啮姬小蜂亚科形成三个独立的支系,研究结果支持它们各自的单系性,但本结果没有明确姬小蜂科的单系性。研究结果同时还支持瑟姬小蜂族、扁股姬小蜂族和狭面姬小蜂族三个族的地位,但不支持姬小蜂族的地位。姬小蜂科的单系性及其与其它小蜂间的关系还需更多的形态学数据和更多的基因序列来进一步研究[动物学报52 (2) : 288 -301 , 2006]。沙忠利 朱朝东 Robert W.MURPHY 黄大卫 Stephen G.COMPTON 2006动物学报2006,52,2:5
7Comparative Skin Histology of Frogs Reveals High-elevation Adaptation of the Tibetan Nanorana parkeri显示文摘Adaptations to extreme environmental conditions are intriguing. Animal skin, which directly interacts with external environment, plays diverse and important roles in adaptive evolution. The thin and bare skin of amphibians is sensitive to external environmental conditions and, thus, it facilitates investigations into adaptations for living in extreme environments. Herein, we compare the structures of skin in four anuran species living at elevations ranging from 100 m to 4500 m to assess phenotypic innovations in the skin of Nanorana parkeri, which lives at extremely high elevations. Analyses reveal similar basic skin structures, but N. parkeri differs from the other species by having more epidermal capillaries and granular glands, which correlate highly with responses to hypoxia and/or ultraviolet(UV) radiation. Further intraspecific comparisons from frogs taken at ~4500 m and ~2900 m reveal that all of the changes are fixed. Changes occurring only in the higher elevation population, such as possessing more skin pigments, may represent local adaptations to coldness and/or UV radiation. These results provide a morphological basis for understanding further the molecular adaptations of these frogs.Chunhua YANG Tingting FU Xinqiang LAN Yun ZHANG Lotanna Micah NNEJI Robert W.MURPHY Yanbo SUN Jing CHE 2019Asian Herpetological Research2019,10,2:3
8A new species of genus Fejervarya (Anura:Dicroglossidae) from northern Thailand显示文摘We describe a new species of frog in the dicroglossid genus Fejervarya from Ban Monjong,Omkoi District,Chiang Mai Province,northern Thailand.Analysis of DNA sequence data from the mitochondrial gene 16 S,advertisement calls,and morphological distinctiveness support recognition of the new species.Matrilineal genealogy suggests that the new population from Chiang Mai is a sister taxon to the South Asian clade that includes F.syhadrensis,F.granosa,and F.pierrei.The new species,Fejervarya chiangmaiensis sp.nov.,differs morphologically from its congeners by its relatively small body size and proportions and the presence of dorsal warts and dermal ridges.Discovery of this new species indicates that the biodiversity of amphibians in this region remains underestimated.Chatmongkon SUWANNAPOOM Zhi-Yong YUAN Nikolay A.POYARKOV Jr. Fang YAN Somboon KAMTAEJA Robert W.MURPHY Jing CHE 2016Zoological Research2016,37,6:2
9Toward a Phylogeny of the Kukri Snakes,Genus Oligodon显示文摘The South and Southeast Asian snake genus Oligodon,known for its egg-eating feeding behavior,has been a taxonomically and systematically challenging group.This work provides the first phylogenetic hypothesis for the genus.We use approximately 1900 base pairs of mitochondrial DNA sequence data to infer the relationships of these snakes,and we examine congruence between the phylogeny and hemipenial characters.A hypothesis for the position of Oligodon within the Colubridae is also proposed.We discuss the implications of the phylogeny for previous taxonomic groupings,and consider the usefulness of the trees in analysis of behavior and biogeography of this genus.Marc D.Green Nikolai L.Orlov Robert W.Murphy 2010Asian Herpetological Research2010,1,1:2
10Discovery of a wild,genetically pure Chinese giant salamander creates new conservation opportunities显示文摘Effective conservation of threatened biota relies on accurate assessments and scientific guidance.As an unfortunate example,Chinese giant salamanders(Andrias,CGS)remain critically endangered in nature.Misguided conservation efforts,e.g.,commercial propagation and releasing of millions of likely non-indigenous or interspecific hybrids,have further compromised conservation initiatives.Limited information on wild populations of CGS poses a significant conservation challenge.Following 18-month long field monitoring,we now report the discovery of a wild population of CGS in a closed nature reserve in Jiangxi Province,China.Genomic assessments reveal its genetic distinctiveness and do not detect genetic admixture with other species.Based on morphological and molecular evidences,we describe this CGS as a new species Andrias jiangxiensis sp.nov.This is the only known species of CGS today with a genetically pure,reproducing,in situ population.This discovery emphasizes the important role that closed nature reserves play in protecting species,and the necessity of integrating long-term field monitoring and genetic assessments.It sets a new pathway for discovering and conserving endangered species,especially for those biotas that are similarly being extirpated by anthropogenic translocations and overexploitation.Jing Chai Chen-Qi Lu Mu-Rong Yi Nian-Hua Dai Xiao-Dong Weng Ming-Xiao Di Yong Peng Yong Tang Qing-Hua Shan Kai Wang Huan-Zhang Liu Hai-Peng Zhao Jie-Qiong Jin Ru-Jun Cao Ping Lu Lai-Chun Luo Robert W.Murphy Ya-Ping Zhang Jing Che 2022Zoological Research2022,43,3:2
11The gap in research on polyploidization between plants and vertebrates:model systems and strategic challenges显示文摘Polyploidization via whole-genome duplications(WGD) is a common phenomenon in organisms.However, investigations into this phenomenon differ greatly between plants and animals. Recent research on polyploid plants illustrates the immediate changes that follow WGDs and the mechanisms behind in both genetic and epigenetic consequences. Unfortunately, equivalent questions remain to be explored in animals. Enlightened by botanical research, the study of polyploidization in vertebrates involves the identification of model animals and the establishment of strategies. Here we review and comparethe research on plants and vertebrates while considering intrageneric or intraspecific variation in genome size.Suitable research methods on recently established polyploidy systems could provide important clues for understanding what happens after WGDs in vertebrates. The approach yields insights into survival and the rarity of polyploidization in vertebrates. The species of Carassius and the allopolyploid system of goldfish 9 common carp hybridization appear to be suitable models for unraveling the evolution and adaptation of polyploid vertebrates.Jing Chai Yuebo Su Feng Huang Shaojun Liu Min Tao Robert W.Murphy Jing Luo 2015Science Bulletin2015,60,17:1

16The variable codons of H5N1 avian influenza A virus haemagglutinin genes显示文摘We investigated the selection pressures on the haemagglutinin genes of H5N1 avian influenza viruses using fixed effects likelihood models. We found evidence of positive selection in the sequences from isolates from 1997 to 2007, except viruses from 2000. The haemagglutinin sequences of viruses from southeast Asia, Hong Kong and China's Mainland were the most polymorphic and had similar nonsyn-onymous profiles. Some sites were positively selected in viruses from most regions and a few of these sites displayed different amino acid patterns. Selection appeared to produce different outcomes in vi-ruses from Europe, Africa and Russia and from different host types. One position was found to be positively selected for human isolates only. Although the functions of some positively selected posi-tions are unknown, our analysis provided evidence of different temporal, spatial and host adaptations for H5N1 avian influenza viruses.Mark J.GIBBS Robert W.MURPHY 2008Science China(Life Sciences)2008,51,11:0
17A cryptic mitochondrial DNA link between North European and West African dogs显示文摘Domestic dogs have an ancient origin and a long history in Africa. Nevertheless, the timing and sources of their introduction into Africa remain enigmatic. Herein, we analyse variation in mitochondrial DNA(mt DNA) D-loop sequences from 345 Nigerian and 37 Kenyan village dogs plus 1530 published sequences of dogs from other parts of Africa, Europe and West Asia. All Kenyan dogs can be assigned to one of three haplogroups(matrilines; clades): A, B, and C, while Nigerian dogs can be assigned to one of four haplogroups A, B, C, and D. None of the African dogs exhibits a matrilineal contribution from the African wolf(Canis lupus lupaster). The genetic signal of a recent demographic expansion is detected in Nigerian dogs from West Africa. The analyses of mitochondrial genomes reveal a maternal genetic link between modern West African and North European dogs indicated by sub-haplogroup D1(but not the entire haplogroup D) coalescing around 12,000 years ago. Incorporating molecular anthropological evidence,we propose that sub-haplogroup D1 in West African dogs could be traced back to the late-glacial dispersals, potentially associated with human hunter-gatherer migration from southwestern Europe.Adeniyi C.Adeola Sheila C.Ommeh Jiao-Jiao Song S.Charles Olaogun Oscar J.Sanke Ting-Ting Yin Guo-Dong Wang Shi-Fang Wu Zhong-Yin Zhou Jacqueline K.Lichoti Bernard R.Agwanda Philip M.Dawuda Robert W.Murphy Min-Sheng Peng Ya-Ping Zhang 2017Journal of Genetics and Genomics2017,44,3:0
18Genetic variation and cryptic lineage diversity of the Nigerian red-headed rock agama Agama agama associate with eco-geographic zones显示文摘Nigeria is an Afrotropical region with considerable ecological heterogeneity and levels of biotic endemism.Among its vertebrate fauna,reptiles have broad distributions,thus,they constitute a compelling system for assessing the impact of ecological variation and geographic isolation on species diversification.The red-headed rock agama,Agama agama,lives in a wide range of habitats and,thus,it may show genetic structuring and diversification.Herein,we tested the hypothesis that ecology affects its genetic structure and population divergence.Bayesian inference phylogenetic analysis of a mitochondrial DNA(mtDNA)gene recovered four well-supported matrilines with strong evidence of genetic structuring consistent with eco-geographic regions.Genetic differences among populations based on the mtDNA also correlated with geographic distance. The ecologicalniche model for the matrilines had a good fit and robust performance. Population divergence alongthe environmental axes was associated with climatic conditions, and temperature ranked highestamong all environmental variables for forest specialists, while precipitation ranked highest for theforest/derived savanna, and savanna specialists. Our results cannot reject the hypothesis that nicheconservatism promotes geographic isolation of the western populations of Nigerian A. agama.Thus, ecological gradients and geographic isolation impact the genetic structure and population divergenceof the lizards. This species might be facing threats due to recent habitat fragmentation,especially in western Nigeria. Conservation actions appear necessary.Lotanna M.NNEJI Adeniyi C.ADEOLA Fang YAN Agboola O.OKEYOYIN Ojo C.OLADIPO Yohanna SAIDU Dinatu SAMUEL Ifeanyi C.NNEJI Akindele O.ADEYI Abiodun B.ONADEKO Temidayo E.OLAGUNJU Olatunde OMOTOSO Segun O.OLADIPO Oluyinka A.IYIOLA John Y.USONGO Timothy AUTA Abbas D.USMAN Halima ABDULLAHI Odion O.IKHIMIUKOR Wei-Wei ZHOU Jie-Qiong JIN Obih A.UGWUMBA Adiaha A.A.UGWUMBA Min-Sheng PENG Robert W.MURPHY Jing CHE 2019Current Zoology2019,65,6:0
19Discovery of Female Laudakia papenfussi Zhao,1998,with Insights into its Phylogenetic Relationships显示文摘The sole voucher of Papenfuss' Rock Agama, Laudakia papenfussi(CIB 775001), an adult male, was collected from Zanda, Tibet, China on July 1,1976 and described in 1998. No information on this species appeared since its description. In September 2014, we collected one female and six males at the type locality. Based on the original description and these newly collected specimens, we re-describe this species. Principal components analysis based on 33 morphological characteristics clearly diagnose L. papenfussi from closely related species. One way ANOVA test shows significant differences among four Tibetan rock agamas for 9 characters at 95% significant level, and 8 characters at 99% significant level. Molecular analyses recover three main clades in Laudakia. The four Tibetan rock agamas place into two geographical groups: Yarlung Zangbo group(L.sacra and L.wui) and the Himalayan group(L.tuberculata and L.papenfussi).Dahu ZOU Fang YAN Ke JIANG Jing CHE Robert W.MURPHY Theodore J.PAPENFUSS Shuangquan DUAN Song HUANG 2016Asian Herpetological Research2016,7,2:0
20Matrilineal Genealogy of Hynobius (Caudata:Hynobiidae) and a Temporal Perspective on Varying Levels of Diversity among Lineages of Salamanders on the Japanese Islands显示文摘Previous work found that different Japanese lineages of salamanders had quite different levels of species and genetic diversity. Lineages vary from having one to several species and the extent of genetic variation among lineages differs substantially. Most speciose,genus Hynobius contains 18 species and several potential cryptic species. We explore genetic diversity in this genus by combining comprehensive sampling and mitochondrial DNA sequences. Based on this and previous analyses of salamanders,relative times of divergence are employed to evaluate the relationship between age and diversity among the four major lineages whose distributions broadly overlap on the islands. For Hynobius,our analyses are congruent with the previously reported high level of cryptic diversity in morphology and allozymes,particularly in species composed of non-sister matrilines. Both species and genetic diversity correlate with the relative ages of the lineages. This correlation indicates that the variation in levels of diversity can be explained,to a considerable extent,by the hypothesis that older insular lineages have accumulated greater diversity. In addition to the Korean Peninsula,H. leechii might have survived in another Pleistocene glacial refugium north of the peninsula and this refugium provided a source of colonization after the last glacial maximum.Yuchi ZHENG Rui PENG Robert W.MURPHY Masaki KURO-O Lujun HU Xiaomao ZENG 2012Asian Herpetological Research2012,3,4:0
