| 1 | Effect of China's rapid development on its iconic giant panda显示文摘Anthropogenic factors affect biodiversity and have led to the contraction or extinction of animal populations worldwide.Here,we use historical demographic data,spanning the past 300 years,to show that a rapid distributional contraction of giant pandas took place during the 18th and 19th centuries alongside the increase in human population.Land-use also underwent a significant change across the areas where giant pandas were found because of government agricultural policy and the introduction of new crops.The impact of social development on giant pandas includes habitat loss and fragmentation,and range reductions.Our findings would facilitate the design of effective conservation strategies that seek to conserve and increase current habitats of this iconic species,especially in areas that our analysis has identified as places where pandas have suffered from high human pressure. | ZHU LiFeng HU YiBo ZHANG ZeJun WEI FuWen | 2013 | Chinese Science Bulletin2013,58,17: | 8 |
| 2 | Seasonal and reproductive variation in chemical constituents of scent signals in wild giant pandas显示文摘Seasonally reproducing animals show many behavioral and physiological changes during the mating period, including increased signaling for intrasexual competition and mate attraction. We collected 102 anogenital gland secretions(AGS) from marking trees in Foping Nature Reserve, and used gas chromatography mass spectrometry to analyze these chemical composition. Of these marks, all but one were from males, confirmed with DNA analysis. We found that several chemical constituents, especially volatile compounds, were present only during the mating season and that the relative abundance of many compounds changed as a function of breeding season, whereas nonvolatile compounds were lower in the mating season. This seasonal variation in chemical composition of AGS most likely plays an important role in governing giant panda reproduction, including mate location, attraction, and male-male competition. The chemical properties of many of these putative chemosignals—such as volatility and longevity—are suggestive of these roles, and undoubtedly contribute to successful reproduction for this species with a characteristically sophisticated chemical communication system. We also found a number of important differences between the chemical constituents of AGS from wild pandas and those found in previous studies with captive pandas, suggesting that inappropriate chemosignal composition may contribute to poor reproductive success in captive breeding programs. | Wenliang Zhou Yonggang Nie Yibo Hu Ronald R.Swaisgood Yaohua Zhang Dingzhen Liu Fuwen Wei | 2019 | Science China(Life Sciences)2019,62,5: | 6 |
| 3 | Precise determination of the reference point coordinates of Shanghai Tianma 65-m radio telescope显示文摘A local survey was implemented at the newly constructed Shanghai Tianma 65-m radio telescope.In this article,the survey implementation and data analysis are described.Particularly,by application of coordinate transformation,dimensionality reduction and step fitting of parameters,as well as adoption of reliability test measures of parameters,the mathematical model of data analysis is simplified,the detrimental effects of observation noises and unevenly spatial coverage of sample points are effectively compressed,the stability and precision of parameter solutions are improved,and so the geocentric three-dimensional coordinates of the reference point of this telescope in the precision of millimeters were determined,and the axisoffset was shown not significant on the precision level of3 mm.The outcome provides important reference to the subsequent activities of antenna maintenance and scientific application,including the establishment of precise antenna orientation model,orientation guidance,fringe searching in data cross-correlation,analysis and application studies of VLBI observations.It is also important archive data for monitoring possible subsidence and lateral displacement of antenna foundation as well as deformation of antenna tracking-rail and structure. | Jinling Li Fuwen Xiong Chenglei Yu Jinwei Zhang Li Guo Qingyuan Fan | 2014 | Chinese Science Bulletin2014,59,21: | 5 |

| 5 | Deposition and properties of highly c-oriented of InN films on sapphire substrates with ECR-plasma-enhanced MOCVD显示文摘InN films with highly c-axis preferred orientation were deposited on sapphire substrate by low-temperature electron cyclotron resonance plasma-enhanced metal organic chemical vapor deposition (ECR-PEMOCVD). Trimethyl indium (TMIn) and N 2 were applied as precursors of In and N, respectively. The quality of as-grown InN films were systematically investigated as a function of TMIn fluxes by means of reflection high-energy electron diffraction (RHEED), X-ray diffraction analysis (XRD), and atomic force microscopy (AFM). The results show that the dense and uniform InN films with highly c-axis preferred orientation are successfully achieved on sapphire substrates under optimized TMIn flux of 0.8 ml min 1 . The InN films reported here will provide various opportunities for the development of high efficiency and high-performance semiconductor devices based on InN material. | Qin, Fuwen Zhang, Dong Bai, Yizhen Ju, Zhenhe Li, Shuangmei Li, Yucai Pang, Jiaqi Bian, Jiming | 2012 | Rare Metals2012,31,2: | 2 |
| 6 | Effect of TMGa flux on GaN films deposited on Ti coated on glass substrates at low temperature显示文摘Highly c-axis-oriented GaN films were deposited on Ti coated glass substrates using low temperature electron cyclotron resonance plasma enhanced metal organic chemical vapor deposition system(ECR-PEMOCVD)with trimethyl gallium(TMGa)as gallium source.The influence of TMGa flux on the properties of GaN films were systematically investigated by reflection high energy electron diffraction(RHEED),X-ray diffraction analysis(XRD),atomic force microscopy(AFM)and Raman scattering.The GaN film with small surface roughness and high c-axis preferred orientation was successfully achieved at the optimized TMGa flux of 1.0 sccm.The ohmic contact characteristic between GaN and Ti layer was clearly demonstrated by the near-linear current-voltage(I-V)curve.The GaN/Ti/glass structure has great potential to dramatically improve the scalability and reduce the cost of solid-state lighting light emitting diodes. | WANG EnPing BIAN JiMing QIN FuWen ZHANG Dong LIU YueMei ZHAO Yue DUAN ZhongWei WANG Shuai | 2013 | Chinese Science Bulletin2013,58,30: | 2 |
| 7 | Lineage-specific evolution of bitter taste receptor genes in the giant and red pandas implies dietary adaptation显示文摘Taste 2 receptors(TAS2R)mediate bitterness perception in mammals,thus are called bitter taste receptors.It is believed that these genes evolved in response to species-specific diets.The giant panda(Ailuropoda melanoleuca)and red panda(Ailurus fulgens styani)in the order Carnivora are specialized herbivores with an almost exclusive bamboo diet(>90%bamboo).Because bamboo is full of bitter tasting compounds,we hypothesized that adaptive evolution has occurred at TAS2R genes in giant and red pandas throughout the course of their dietary shift.Here,we characterized 195 TAS2R genes in 9 Carnivora species and examined selective pressures on these genes.We found that both pandas harbor more putative functional TAS2R genes than other carnivores,and pseudogenized TAS2R genes in the giant panda are different from the red panda.The purifying selection on TAS2R1,TAS2R9 and TAS2R38 in the giant panda,and TAS2R62 in the red panda,has been strengthened throughout the course of adaptation to bamboo diet,while selective constraint on TAS2R4 and TAS2R38 in the red panda is relaxed.Remarkably,a few positively selected sites on TAS2R42 have been specifically detected in the giant panda.These results suggest an adaptive response in both pandas to a dietary shift from carnivory to herbivory,and TAS2R genes evolved independently in the 2 pandas.Our findings provide new insight into the molecular basis of mammalian sensory evolution and the process of adaptation to new ecological niches. | Lei SHAN Qi WU Le WANG Lei ZHANG Fuwen WEI | 2018 | Integrative Zoology2018,13,2: | 2 |
| 8 | Ecological scale and seasonal heterogeneity in the spatial behaviors of giant pandas显示文摘We report on the first study to track the spatial behaviors of wild giant pandas(Ailuropoda melanoleuca)using high-resolution global positioning system(GPS)telemetry.Between 2008 and 2009,4 pandas(2 male and 2 fe-male)were tracked in Foping Reserve,China for an average of 305 days(±54.8 SE).Panda home ranges were larger than those of previous very high frequency tracking studies,with a bimodal distribution of space-use and distinct winter and summer centers of activity.Home range sizes were larger in winter than in summer,although there was considerable individual variability.All tracked pandas exhibited individualistic,unoriented and multi-phasic movement paths,with a high level of tortuosity within seasonal core habitats and directed,linear,large-scale movements between habitats.Pandas moved from low elevation winter habitats to high elevation(>2000 m)summer habitats in May,when temperatures averaged 17.5°C(±0.3 SE),and these large-scale movements took<1 month to complete.The peak in panda mean elevation occurred in Jul,after which they began slow,large-scale movements back to winter habitats that were completed in Nov.An adult female panda made 2 long-distance movements during the mating season.Pandas remain close to rivers and streams during winter,possi-bly reflecting the elevated water requirements to digest their high-fiber food.Panda movement path tortuosity and first-passage-time as a function of spatial scale indicated a mean peak in habitat search effort and patch use of approximately 700 m.Despite a high degree of spatial overlap between panda home ranges,particularly in winter,we detected neither avoidance nor attraction behavior between conspecifics. | Zejun ZHANG James K.SHEPPARD Ronald R.SWAISGOOD Guan WANG Yonggang NIE Wei WEI Naxun ZHAO Fuwen WEI | 2014 | Integrative Zoology2014,9,1: | 1 |

| 12 | On the origin of SARS-CoV-2——The blind watchmaker argument显示文摘In the comparison with SARS-CoVof 2003,SARS-CoV-2 is extremely well adapted to the human populations and its adaptive shift from the animal host to humans must have been even more extensive.By the blind watchmaker argument,such an adaptive shift can only happen prior to the onset of the current pandemic and with the aid of step-by-step selection. | Chung-I Wu Haijun Wen Jian Lu Xiao-dong Su Alice CHughes Weiwei Zhai Chen Chen Hua Chen Mingkun Li Shuhui Song Zhaohui Qian Qihui Wang Bingjie Chen Zixiao Guo Yongsen Ruan Xuemei Lu Fuwen Wei Li Jin Le Kang Yongbiao Xue Guoping Zhao Ya-Ping Zhang | 2021 | Science China(Life Sciences)2021,64,9: | 1 |
| 13 | Numerical simulation and analysis for collapse responses of RC frame structures under earthquake显示文摘In this paper,a discrete element model for collapse simulation of RC frame structure is constructed by discretizing the structure into a few elements and spring groups.This model introduces special hysteretic models of connected springs for arbitrary loading path and also takes into account reasonable failure criteria for springs considering coupling effect of shear and axial force.Based on the discrete element model,a computer program is developed to simulate the whole process of RC frame structures from initial state to collapse under earthquakes.Particularly,the contact-impact problem between discrete elements has been treated with effective measures.Then,the program is employed to study the collapse mechanism of a real building in Wenchuan earthquake-hit area;the result of which shows that the simulation program developed based on the new model can realistically simulate the seismic collapse process of RC frame structures. | Fuwen ZHANG Xilin LU Chao YIN | 2009 | Frontiers of Structural and Civil Engineering2009,3,4: | 0 |
| 14 | Estimate of contribution of near-inertial waves to the velocity shear in the Bay of Bengal based on mooring observations from2013 to 2014显示文摘Near-inertial motions contribute most of the velocity shear in the upper ocean.In the Bay of Bengal(BoB),the annual-mean energy flux from the wind to near-inertial motions in the mixed layer in 2013 is dominated by tropical cyclone(TC)processes.However,due to the lack of long-term observations of velocity profiles,our knowledge about interior near-inertial waves(NIWs)as well as their shear features is limited.In this study,we quantified the contribution of NIWs to shear by integrating the wavenumber-frequency spectra estimated from velocity profiles in the upper layers(40-440 m)of the southern Bo B from April 2013 to May 2014.It is shown that the annual-mean proportion of near-inertial shear out of the total is approximately 50%,and the high contribution is mainly due to the enhancement of the TC processes during which the near-inertial shear accounts for nearly 80%of the total.In the steady monsoon seasons,the near-inertial shear is dominant to or at least comparable with the subinertial shear.The contribution of NIWs to the total shear is lower during the summer monsoon than during the winter monsoon owing to more active mesoscale eddies and higher subinertial shear during the summer monsoon.The Doppler shifting of the M_(2)internal tide has little effect on the main results since the proportion of shear from the tidal motions is much lower than that from the near-inertial and subinertial motions. | Shanwu Zhang Yun Qiu Hangyu Chen Junqiang Shen Junpeng Zhang Jing Cha Fuwen Qiu Chunsheng Jing | 2021 | Acta Oceanologica Sinica2021,40,11: | 0 |
| 15 | Sea level anomalies in the northwestern Pacific during 2011 associated with La Nina and negative Indian Ocean Dipole显示文摘The sea level anomalies(SLAs)pattern in the northwestern Pacific delineated significant differences between La Ni?a events occurring with and without negative Indian Ocean Dipole(IOD)events.During the pure La Ni?a events,positive the sea surface level anomalies(SLAs)appear in the northwestern Pacific,but SLAs are weakened and negative SLAs appear in the northwestern Pacific under the contribution of the negative IOD events in 2010/2011.The negative IOD events can trigger significant westerly wind anomalies in the western tropical Pacific,which lead to the breakdown of the pronounced positive SLAs in the northwestern Pacific.Meanwhile,negative SLAs excited by the positive wind stress curl near the dateline propagated westward in the form of Rossby waves until it approached the western Pacific boundary in mid-2011,which maintained and enhanced the negative phase of SLAs in the northwestern Pacific and eventually,it could significantly influence the bifurcation and transport of the North Equatorial Current(NEC). | Fuwen Qiu Yun Qiu Aijun Pan Jing Cha Shanwu Zhang | 2019 | Acta Oceanologica Sinica2019,38,11: | 0 |
| 16 | ZnO Films on Transferable and Low Thermal Resistance Graphite Substrate Grown by Ultrasonic Spray Pyrolysis显示文摘ZnO thin films were deposited on graphite substrates by ultrasonic spray pyrolysis method with Zn(CH 3 COO) 2 ·2H 2 O aqueous solution as precursor. The crystalline structure, morphology, and optical properties of the as-grown ZnO films were investigated systematically as a function of deposition temperature and growth time. Near-band edge ultraviolet(UV) emission was observed in room temperature photoluminescence spectra for the optimized samples, yet the usually observed defect related deep level emissions were nearly undetectable, indicating that high optical quality ZnO thin fi lms could be achieved via this ultrasonic spray pyrolysis method. Considering the features of transferable and low thermal resistance of the graphite substrates, the achievement will be of special interest for the development of high-power semiconductor devices with suffi cient power durability. | 边继明 MA Xiaowen SUN Jingchang ZHANG Zhikun WANG Yuxin QIN Fuwen LUO Yingmin ZHANG Yuzhi FU Xianping | 2014 | Journal of Wuhan University of Technology(Materials Science)2014,29,3: | 0 |

| 18 | Ecological Optimization Design Methods for the Green Space System in Densely Built-up Areas显示文摘This paper is aimed at studying the environmental degradation of densely built-up areas in the process of urbanization in China. In consideration of the severe environmental conditions of the densely built-up areas, such as the lack of green space and open space, ecological disturbance in some areas, poor landscape quality, this paper focused on the ecological space optimization in the process of urban renewal. Firstly, theories related to this field were analyzed, and a comprehensive ecological efficiency evaluation system was established based on disciplines such as urban ecology, landscape ecology, urban sociology, behavioral psychology, biology, urban planning and design. Secondly, this system was used to judge the ecological efficiency of typical blocks on GIS platform and to find out the key spatial nodes that need to be updated. Thirdly, in different cases, space optimization projects with different theories were designed, and the spatial model of influence was used to comprehensively evaluate their ecological efficiency. Finally, the parameters under different conditions were corrected to get a systematic system for evaluating the green space system in densely built-up areas. Due to the lack of understanding of the ecological function of green space in the past, the environmental condition of densely built-up areas is not good. Therefore, the most important task of urban organic renewal is ecological restoration. In this paper, the exploration is based on the reservation for built-up areas to avoid repeated reconstruction and interference. Authors of this paper tried to find out a way to rebuild green space system that performed more complex functions with limited spatial resources. The application of 'micro-transformation' of green space system in densely built-up areas turns out to improve the quality of landscape while reducing the construction cost. | BI Linglan ZHANG Fuwen ZHANG Fangming | 2018 | Journal of Landscape Research2018,10,4: | 0 |
| 19 | Sm-Nd,Pb-Pb and Rb-Sr Isotopic Dating and Its Dynamic Implications for the Proterozoic Augen Granite in the Yunkai Area,Western Guangdong Province显示文摘The samples of ductile-rheologic deformational augen granite from the Yunkai uplift area, western Guangdong province, were determined by the whole-rock Sm-Nd, Pb-Pb and Rb-Sr isotopic dating to have an Sm-Nd isochron age of 1414±68 Ma, a Pb-Pb isochron age of 1388±90 Ma and a Rb-Sr isochron age of 490±36 Ma. The first two ages are interpreted as the formation age of this suite of granite and the last age represents the timing of the tec-tono-thermal event of Caledonian ductile-rheologic shear partial melting. It is indicated that in the study area not only an orogeny took place in the Caledonian, but also a more important tectono-magmatic activity occurred in the Meso-proterozoic there , which may be related to the subduction-collision between the Yangtze block and Cathaysia block. | PENG Songbai ZHANG Yeming ZHAN Mingguo CHEN Fuwen QIU Ruizhao | 2000 | Acta Geologica Sinica(English Edition)2000,74,2: | 0 |
| 20 | Interactions of Microplastics and Methane Seepage in the Deep-Sea Environment显示文摘Microplastics(MPs)are important exempla of the Anthropocene and are exerting an increasing impact on Earth’s carbon cycle.The huge imbalance between the MPs floating on the marine surface and those that are estimated to have been introduced into the ocean necessitates a detailed assessment of marine MP sinks.Here,we demonstrate that cold seep sediments,which are characterized by methane fluid seepage and a chemosynthetic ecosystem,effectively capture and accommodate small-scale(<100μm)MPs,with 16 types of MPs being detected.The abundance of MPs in the surface of the sediment is higher in methane-seepage locations than in non-seepage areas.Methane seepage is beneficial to the accumulation,fragmentation,increased diversity,and aging of MPs.In turn,the rough surfaces of MPs contribute to the sequestration of the electron acceptor ferric oxide,which is associated with the anaerobic oxidation of methane(AOM).The efficiency of the AOM determines whether the seeping methane(which has a greenhouse effect 83 times greater than that of CO_(2)over a 20-year period)can enter the atmosphere,which is important to the global methane cycle,since the deep-sea environment is regarded as the largest methane reservoir associated with natural gas hydrates. | Jing-Chun Feng Zhifeng Yang Wenliang Zhou Xingwei Feng Fuwen Wei Bo Li Chuanxin Ma Si Zhang Linlin Xia Yanpeng Cai Yi Wang | 2023 | Engineering2023,,10: | 0 |
