| 1 | GENETIC DIVERSITY AMONG CHINESE SIKA DEER (CERVUS NIPPON) POPULATIONS AND RELATIONSHIPS BETWEEN CHINESE AND JAPANESE SIKA DEER显示文摘Sika deer (Cervus nippon) is a cervid endemic to mainland and insular Asia and endan-gered. We analyzed variation in the mitochondrial DNA (mtDNA) control region for four subspecies to understand the genetic diversity, population structure and evolutionary history in China. 335 bp were se-quenced and eight haplotypes were identified based on 25 variable sites among the populations. Sika deer in China showed lower genetic diversity, sug-gesting a small effective population size due to habi-tat fragmentation, a low number of founder individu-als, or the narrow breeding program. AMOVA analy-sis indicated that there was significant genetic subdi-vision among the four populations, but no correlation between the genetic and geographic distance. Phy-logenetic analyses also revealed that Chinese sika deer may be divided into three genetic clades, but the genetic structure among Chinese populations was inconsistent with subspecies designations and pre-sent geographic distribution. Including the sequence data of Japanese sika deer, the results indicated that Chinese populations were more closely related to Southern Japanese populations than to the Northern Japanese one, and the Taiwan population was closer to populations of Northeastern China and Sichuan than to those of Southern China. | Lü Xiaoping WEI Fuwen LIMing YANG Guang LIU Hai | 2006 | Chinese Science Bulletin2006，51，4： | 7 |
| 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 | First evidence of prey capture and meat eating by wild Yunnan snub-nosed monkeys Rhinopithecus bieti in Yunnan,China显示文摘Most extant nonhuman primates occasionally prey on fast-moving, warm-blooded animals; however, Indriidae, Lepilemuridae,and Colobinae either scavenged for meat or did not eat meat at all. Here we report six cases of animal consumptionby the snub-nosed monkey Rhinopithecus bieti in a wild, habituated group between 2004 and 2009 in Yunnan, China. At present,only males in an all-male unit within the study group were involved in active hunting. Such a male-biased activity may be relatedto the group structure and spatial spread of R. bieti. Two females were observed eating freshly killed birds. The findings confirmedthat R. bieti engaged in scavenging and, when hunting, employed a cranio-cervical bite to kill their prey. Meat eating islikely a nutrient maximization feeding strategy in R. bieti, especially in males. A begging behavior occurred after successful preycapture. Although begging was observed, no sharing of the meat was seen. The present findings illuminate the dietary diversity ofR. bieti and their ability to expand their dietary | Baoping REN Dayong LI Zhijin LIU Baoguo LI Fuwen WEI Ming LI | 2010 | Current Zoology2010，56，2： | 4 |
| 4 | 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 |

| 12 | Luminescent and thermometric properties of dual emitting Eu^(2+)/Sm^(3+) co-doped Sr_(4)La(PO_(4))_(3)O phosphor based on energy transfer显示文摘Eu^(2+)/Sm^(3+)co-doped dual-emitting Sr_(4)La(PO_(4))_(3)O phosphors were synthesized through a convenient high temperature solid state reaction in reductive atmosphere.The structure,luminescence,energy transfer and temperature-dependent luminescence properties of Eu^(2+)/Sm^(3+)co-doped Sr_(4)La(PO_(4))_(3)O phosphors were researched and analyzed in detail.The blue emission of Eu^(2+)and the red emission of Sm^(3+)can work together as FIR signals.Based on the different response characteristics of these two ion emissions to temperature,Sr_(4)La(PO_(4))_(3)O:Eu^(2+)/Sm^(^(3+))phosphor achieves the relative sensitivity of0.48384%/K and a wide range of temperature measurements from room temperature to 573 K.The results reveal that the Sr_(4)La(PO_(4))_(3)O:Eu^(2+)/Sm^(3+)phosphor has application prospect in the field of high temperature optical thermometry.The energy transfer mechanism is proved to be the dipole-dipole interaction between Eu^(2+)and Sm^(3+)ions. | Fuwen Liu Degang Deng Ming Wu Bowen Chen Liuyan Zhou Shiqing Xu | 2021 | Journal of Rare Earths2021，39，3： | 1 |
| 13 | Comparative analysis reveals epigenomic evolution related to species traits and genomic imprinting in mammals显示文摘DNA methylation is an epigenetic modification that plays a crucial role in various regulatory processes,including gene expression regulation,transposable element repression,and genomic imprinting.However,most studies on DNA methylation have been conducted in humans and other model species,whereas the dynamics of DNA methylation across mammals remain poorly explored,limiting our understanding of epigenomic evolution in mammals and the evolutionary impacts of conserved and lineage-specific DNA methylation.Here,we generated and gathered comparative epigenomic data from 13 mammalian species,including two marsupial species,to demonstrate that DNA methylation plays critical roles in several aspects of gene evolution and species trait evolution.We found that the species-specific DNA methylation of promoters and noncoding elements correlates with species-specific traits such as body patterning,indicating that DNA methylation might help establish or maintain interspecies differences in gene regulation that shape phenotypes.For a broader view,we investigated the evolutionary histories of 88 known imprinting control regions across mammals to identify their evolutionary origins.By analyzing the features of known and newly identified potential imprints in all studied mammals,we found that genomic imprinting may function in embryonic development through the binding of specific transcription factors.Our findings show that DNA methylation and the complex interaction between the genome and epigenome have a significant impact on mammalian evolution,suggesting that evolutionary epigenomics should be incorporated to develop a unified evolutionary theory. | Yisi Hu Shenli Yuan Xin Du Jiang Liu Wenliang Zhou Fuwen Wei | 2023 | The Innovation2023，4，3： | 0 |
| 14 | An optical thermometer with high sensitivity and superior signal discriminability based on dual-emitting Ce^(3+)/Eu^(2+)co-doped La5Si2BO13 thermochromic phosphor显示文摘A novel non-contact optical thermometer,qualified with high sensitivity and temperature resolution,is urgently needed for temperature measuring of micro devices,moving objects and specific severe environments.Hence,a series of dual-emitting La_(5)Si_(2)BO_(13):Ce^(3+),Eu^(2+)phosphors were synthesized.The two ions show diverse responses with the changing in temperature.The variational emissions of Ce^(3+)and Eu^(2+)can be converted to FIR(fluorescence intensity ratio)signals.The maximal absolute sensitivity Sa and relative sensitivity Sr reach up to 0.07526%/K and 3.2241%/K,respectively.It is worthy noting that the Sa and Sr possess the same variation tendency and both have high values in the low temperature region(293-373 K),showing the great temperature measuring property especially in low temperature region.The temperature sensing characteristics are superior to the results of most previous reports.The energy transfer(ET)process is certified to occur from Ce^(3+)to Eu^(2+)ions.These studies indicate that La_(5)Si_(2)BO_(13):Ce^(3+),Eu^(2+)phosphor could have a good prospect for optical thermometry. | Fuwen Liu Ying Tian Degang Deng Ming Wu Bowen Chen Liuyan Zhou Shiqing Xu | 2021 | Journal of Rare Earths2021，39，11： | 0 |
| 15 | Ecological civilization: China's effort to build a shared future for all life on Earth显示文摘After hundreds of years of technological revolution and rapid development, humanity has reached a moment of crisis in its relationship with nature [1]. To find better solutions to address global challenges, holistic thinking is required to integrate environmental goals with human activities. Some of these approaches include sustainable development (SD), the planetary boundaries (PB) and, in China,ecological civilization (EC) based on the unity of nature and man (UNM)[2]. | Fuwen Wei Shuhong Cui Ning Liu Jiang Chang Xiaoge Ping Tianxiao Ma Jing Xu Ronald R Swaisgood Harvey Locke | 2021 | National Science Review2021，8，7： | 0 |
