| 1 | Petrology and mineral chemistry of new ureilites found in Grove Mountains,Antarctica显示文摘Petrography and mineral chemistry of two new ureilites, GRV 021512 and 022931, from the Grove Mountains, Antarctica, are reported in this paper. GRV 021512 exhibits a typical ureilite texture, and consists of 48.3% olivine, 9.4% pigeonite and 38.1% carbo- naceous interstitial material and/or reduction product. GRV 022931 has a cataclastic porphyritic texture, and consists of 19.1% olivine and 14.1% pigeonite embedded in 66.3% carbonaceous interstitial material and/or reduction product. The coarse-grained olivine and pigeonite in both meteorites have homogeneous cores, and they are FeO-rich within the range of the ferroan subgroup (subgroup I) of olivine-pigeonite ureilites. All olivine grains of the meteorites show reduction zones along boundaries and cracks. Abundant diamond coexists with graphite as graphite-rich patches and veins in the carbonaceous interstitial material. Petrogenesis of both meteorites and the origin of diamond are discussed. | Bingkui Miao Yangting Lin Guiqin Wang Daode Wang Ziyuan Ouyang | 2008 | Progress in Natural Science:Materials International2008，18，4： | 8 |
| 2 | A New Species of the Genus Tylototriton (Urodela: Salamandridae) from Northeastern Hunan Province, China显示文摘We describe a new species from the family Salamandridae from northeastern Hunan Province of China based on morphological and molecular genetic evidences.The new species,Tylototriton liuyangensis,is a member of the T.asperrimus group,and shares a number of similarities with T.wenxianensis and T.broadoridgus.The dorsal surface of the new Tylototriton species is completely black,with nodule-like warts distributed evenly along the lateral margin of dorsal body,and there is no transverse striae between the warts.There are several diagnostic characters of the new species that differ from those of T.wenxianensis and T.broadoridgus as follows:(1)the interorbital space(IOS)is comparatively wide;(2)there is a bony ridge present on the dorsal head surface,running along the upper eyelids;(3)the space between axilla and groin(AGS)is comparatively large,with the mean male AGS approximately equal to 50%of the snout-vent length(SVL)and the mean female AGS being 53%of SVL;and(4)there is a small genital armature on the anterior angle of labial folds present inside the anal fissure of adult males during the breeding season.The result from the molecular phylogenetic analysis of the genus Tylototriton(including the type specimen of the new species)based on the complete DNA sequence of the mitochondrial ND2 gene(1035 bp)indicated that the new species was similar to T.wenxianensis,T.dabienicus,and T.broadoridgus,but formed an independent clade.This result was consistent with the morphological analysis above,supporting that the Liuyang Population represented a distinct species. | Daode YANG Jianping JIANG Youhui SHEN Dongbo FEI | 2014 | Asian Herpetological Research2014，5，1： | 5 |
| 3 | Protist Interactions and Seasonal Dynamics in the Coast of Yantai, Northern Yellow Sea of China as Revealed by Metabarcoding显示文摘Facilitated by the high-throughput sequencing(HTS)technique,the importance of protists to aquatic systems has been widely acknowledged in the last decade.However,information of protistan biotic interactions and seasonal dynamics is much less known in the coast ecosystem with intensive anthropic disturbance.In this study,year-round changes of protist community composition and diversity in the coastal water of Yantai,a city along the northern Yellow Sea in China,were investigated using HTS for the V4 region of 18S rDNA.The interactions among protist groups were also analyzed using the co-occurrence network.Data analyses showed that Alveolata,Chlorophyta,and Stramenopiles are the most dominant phytoplanktonic protists in the investigated coastal area.The community composition displayed strong seasonal variation.The abundant families Dino-Group-I-Clade-1 and Ulotrichales_X had higher proportions in spring and summer,while Bathycoccaceae exhibited higher ratios in autumn and winter.Alpha diversities(Shannon and Simpson)were the highest in autumn and the lowest in spring(ANOVA test,P<0.05).Nutrients(SiO42−,PO43−),total organic carbon(TOC),and pH seemed to drive the variation of alpha diversity,while temperature,PO43−and TON were the most significant factors influencing the whole protist community.Co-variance network analyses reveal frequent co-occurrence events among ciliates,chlorophytes and dinoflagellate,suggesting biotic interactions have been induced by predation,parasitism and mixotrophy. | FU Yingjun ZHENG Pengfei ZHANG Xiaoli ZHANG Qianqian JI Daode | 2020 | Journal of Ocean University of China2020，19，4： | 3 |
| 4 | A New Species of Hemiphyllodactylus Bleeker,1860(Reptilia:Squamata)from Hunan Province,China显示文摘A new species of gekkonid,Hemiphyllodactylus dupanglingensis sp.nov.,is described based on six specimens from Hunan Province,China.The new species is phylogenetically close to H.zugi,H.hongkongensis,H.dushanensis,and H.huishuiensis,and can be distinguished from its congeners by the following combination of cha racters:9-11 chin scales;postmental scales enlarged;9-12 infralabials,11-14 supralabials;14-16 dorsal scales and 10-11 ventral scales longitudinally arranged at the midbody contained with one eye diameter;a manual lamellar formula of 4-4-5-4 or 4-5-5-4 and a pedal lamellar formula of 4-5-5-5 or 5-6-6-4;21-25 continuous precloacal and femoral pores in males. | Bing ZHANG Tianyu QIAN Xiangjin JIANG Bo CAI Xuejian DENG Daode YANG | 2020 | Asian Herpetological Research2020，11，3： | 3 |
| 5 | Cosmic-ray exposure and gas retention ages of the Guang-mingshan(H5) chondrite显示文摘Isotopic compositions of noble gases from the Guangmingshan chondrite were analyzed. Based on the analyses of cosmogenic nuclei, cosmic-ray exposure age of the meteorite is (65±10.0) Ma (3He), (80±12) Ma (21Ne) and (65±10.0) Ma (38Ar), with an average of 70 Ma. This is the highest exposure age of H-group ordinary chondrites. Gas retention ages of K-Ar and U, Th-4He are (4230±100) Ma and (3300±60) Ma, respectively. The smaller ages of 3He than 21Ne and 4He than Ar suggest that both 3He and 4He lost together. This is probably related to a solar heating effect of a meteorite with a small perihelion during the last exposure period. | WANG Daode LIN Yangting LIU Jinyuan | 2001 | Chinese Science Bulletin2001，46，18： | 2 |
| 6 | Noble gas and cosmic-ray exposure age of Juancheng chondrite显示文摘The analytical results of noble gase in recently fallen Juancheng chondrite indicate that cosmic-ray ages of cosmogenic nuclei of 3He, 21Ne and 38Ar are 5.1, 5.0 and 5.8 Ma, respectively, averaging 5.3 Ma. The gas retention ages radiogenic nuclei of 4He and 40Ar are 3200 and 4 200 Ma, respectively. The average cosmic-ray age shows that it has occurred at breakup of the meteoroid from its parent body by impact before 5.3 Ma. | WANG Daode and WANG Ruitian Guangzhou Institute of Geochemistry, Chinese Academy of Sciences , Guangzhou 510640, China Heze Bureau of Seismology, Shandong Province , Heze 274026, China | 1999 | Chinese Science Bulletin1999，44，12： | 2 |
| 7 | Reduced salinity interacts with ultraviolet radiation to alter photosystem Ⅱ function in diatom Skeletonema costatum显示文摘To investigate the effect of reduced salinity on diatoms’ capacity to cope with changing ultraviolet radiation(U VR) and photosynthetically active radiation(PAR),Skeletonema costatum was grown in a range of salinity(15,25,and 35).The photo system Ⅱ(PSⅡ) function was analyzed by increasing PAR and UVR to mimic a mixing event in turbulent waters.The re sults show that high UVR exposure significantly reduced PSII activity,especially in cells grown at low salinity.UVR,but not salinity,stimulated the ’removal’ rate of PSII protein PsbA.Salinity alone,in the range of 15 to 35,did not regulate PSⅡ acceptor region;however,the low salinity+UVR treatment decreased the energy flux for electron transport per PSⅡ reaction center in S.costatum.It showed that low salinity exacerbated the damaging effect of UVR on PSⅡ function in S.costatum by suppressing Psb A protein synthe sis and modifying the photochemistry of PSⅡ.Although higher catalase(CAT) activity and NPQs were induced,they were unable to prevent the combined damage effect of low salinity+UVR.Our findings indicate that reduced salinity and increased UVR potentially affect the abundance and distribution of S.costatum with the escalation of climate disturbances. | Shasha ZANG Fang YAN Daode YU Jingjing SONG Lei WANG Zhiguang XU Hongyan WU | 2022 | Journal of Oceanology and Limnology2022，40，4： | 1 |

| 10 | Rapid identification of spinal ventral and dorsal roots using a quartz crystal microbalance显示文摘The fast and accurate identification of nerve tracts is critical for successful nerve anastomosis.Taking advantage of differences in acetylcholinesterase content between the spinal ventral and dorsal roots,we developed a novel quartz crystal microbalance method to distinguish between these nerves based on acetylcholinesterase antibody reactivity.The acetylcholinesterase antibody was immobilized on the electrode surface of a quartz crystal microbalance and reacted with the acetylcholinesterase in sample solution.The formed antigen and antibody complexes added to the mass of the electrode inducing a change in frequency of the electrode.The spinal ventral and dorsal roots were distinguished by the change in frequency.The ventral and dorsal roots were cut into 1 to 2-mm long segments and then soaked in 250 μL PBS.Acetylcholinesterase antibody was immobilized on the quartz crystal microbalance gold electrode surface.The results revealed that in 10 minutes,both spinal ventral and dorsal roots induced a frequency change;however,the frequency change induced by the ventral roots was notably higher than that induced by the dorsal roots.No change was induced by bovine serum albumin or PBS.These results clearly demonstrate that a quartz crystal microbalance sensor can be used as a rapid,highly sensitive and accurate detection tool for the quick identification of spinal nerve roots intraoperatively. | Tao Sui Jun Que Dechao Kong Hao Xie Daode Wang Kun Shi Xiaojian Cao Xiang Li | 2013 | Neural Regeneration Research2013，8，8： | 1 |

| 15 | Grove Mountains (GRV) 024237: A new ureilite from Antarctica显示文摘Ureilites share the characteristics of differentiated meteorites and of primary chondrites. GRV 024237 is a ureilite, which was found in the 19th Chinese National Antarctic Research Expedition (CHINARE), at the No. 4 moraine, Grove Mountains, Antarctica. GRV 024237 consists mainly of coarse-grained olivine (60 vol%), pigeonite (30 vol%) and opaque minerals (10 vol%). Tri-junction texture between olivine and pigeonite is common. Carbonaceous materials with minor amounts of troilite and nickel-iron metal were observed as interstitial phases. The Fa value of olivine composition varies from 6.2 to 16.8 from rim to core, but pyroxene is homogeneous in composition, with Fs 14.0 to 15.5. Both olivine and pyroxene have normal extinctions. Net-like iron or limonite veins filled in the fractures of olivine and pyroxene, and no diamond was observed. Based on petrographic and mineralogical features, GRV 024237 is a Type I and Group 2 monomict ureilite. | JIANG Xiaoying WANG Guiqin WANG Daode MIAO Bingkui | 2012 | Advances in Polar Science2012，23，1： | 1 |

| 17 | A New Species of the Genus Protobothrops(Squamata: Viperidae) from Southern Tibet, China and Sikkim, India显示文摘A new species of the genus Protobothrops Hoge & Romano-Hoge, 1983, was described from Jilong County, southern Tibet, China, and Chungthang, northern Sikkim, India. It differs from congeners by the following characters: 1) relatively large body size(total length up to 1510 mm); 2) dorsal scale rows 25–25–19; 3) except for the smooth outermost row, dorsal scales are weakly keeled; 4) relatively high number of ventral(198–216) and subcaudal(65–76 pairs) scales; 5) 7–8 supralabials; 6) 11 to 13 infralabials; 7) dorsal head uniform dark brown, laterally a reddish-brown obscure postocular streak; 8) dorsum of trunk and tail olive, with distinct black edged red brown transverse bands across the body and tail; and 9) eye from bright brown and reddish brown to mildly brown. The new species was also observed from the Haa Valley in western Bhutan. | Hujun PAN Basundhara CHETTRI Daode YANG Ke JIANG Kai WANG Liang ZHANG Gernot VOGEL | 2013 | Asian Herpetological Research2013，4，2： | 1 |
| 18 | Using Head Patch Pattern as a Reliable Biometric Character for Noninvasive Individual Recognition of an Endangered Pitviper Protobothrops mangshanensis显示文摘Mangshan pitviper, Protobothrops mangshanensis(formerly Zhaoermia mangshanensis) is endemic to China. Unfortunately, due to the decreasing size of its wild populations, this snake has been listed as critically endangered. Research carried out on the Mangshan pitviper's population ecology and captive reproduction has revealed that the unique head patch patterns of different individuals may potentially be used as a noninvasive recognition biometric character. We collected head patch pattern images of 40 individuals of P. mangshanensis between 1994 and 2011. By comparing each pitviper's head patch pattern, we found that the head patch pattern of individual snakes was different and unique. Additionally, we observed and recorded the head patch pattern characters of four adults and five juveniles before and after ecdysis. Our findings confirmed that head patch patterns of Mangshan pitvipers are unique and stable, remaining unchanged after ecdysis. Thus, individuals can be quickly identified by examining the head patch pattern within a specific recognition area on the head. This method may be useful for noninvasive individual recognition in many other species that display color patch pattern variations, especially in studies of endangered species where the use of invasive marking techniques is undesirable. | Daode YANG Sikan CHEN Yuanhui CHEN Yuying YAN | 2013 | Asian Herpetological Research2013，4，2： | 1 |
| 19 | Neutron capture effects and pre-atmospheric sizes of meteoroids显示文摘Excesses of 80Kr and 82Kr, produced by secondary neutron capture effects of 79Br and 81Br, were observed in meteorites. Epithermal neutron flux, Jn (30—300 eV), and fast neutron flux, Jn( > 5 MeV), were determined according to reactions of 79Br(n, gb)80Kr, 81Br(n, gb)82Kr, and 24Mg(n, a)21Ne, respectively. Cosmogenic noble gases of several ordinary chondrites fell in China indicate a positive relationship between Jn (30—300 eV)/Jn ( > 5 MeV) ratio and Jn (30—300 eV). This suggests large pre-atmospheric sizes of the meteorites, and a considerable fraction of the secondary neutrons were slowed down to epithermal energy. According to its relationship with Jn (30—300 eV)/Jn ( > 5 MeV) ratio, the pre-atmospheric minimum radii and masses of several Chinese chondrites were estimated as below: Zhaodong: 60 cm, 3200 kg; Laochengzhen: 23 cm, 490 kg; Suizhou: 31 cm, 450 kg; Xi Ujimgin: 22 cm, 160 kg; Dongtai: 21 cm, 140 kg. | WANG Daode & LIN Yangting Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, Guangzhou 510640, China Correspondence should be addressed to Wang Daode (e-mail: gzwangdd @public.guangzhou.gd.cn) | 2003 | Chinese Science Bulletin2003，48，20： | 1 |
| 20 | INSPIRATION FROM STUDY OF ANTARCTIC METEORITES 1:PETROGRAPHIC AND COMPOSITIONAL EVIDENCES FOR EARLY CONTINUOUS CHEMICAL FRACTIONATION OF THE SOLAR NEBULA显示文摘Bulk concentrations of Ir, Os, Co and other siderophile elements of metal phase in chondrites increase significantly with degree of oxidation, which together with Co-content of kamacite and Fa-content of olivine, reveal a continuous variation of redox in chondrites. Intermediate groups of E/H, H/L, L/LL, and LL/C, lying between E and H, H and L, L and LL, LL and C, respectively, were proposed based on Co content in kamacite, Fa value of olivine, Fs value of low-Ca pyroxene, bulk concentrations of Ir, Os and Co of metal phase and other taxonomic parameters. The discovery of intermediate groups increases the number of chemical groups of chondrites from 9 to 13. Both variation of redox in chondrites and presence of the intermediate groups of chondrites suggest a continuous chemical fractionation in the primordial solar nebula. | Wang Daode and Lin YangtingInstitute of Geochemistry, Guangzhou Branch, Academia Sinica, Guangzhou 510640 | 1992 | Chinese Journal of Polar Science1992，3，1： | 0 |
