2High-performance silicon−graphene hybrid plasmonic waveguide photodetectors beyond 1.55μm显示文摘Graphene has attracted much attention for the realization of high-speed photodetection for silicon photonics over a wide wavelength range.However,the reported fast graphene photodetectors mainly operate in the 1.55μm wavelength band.In this work,we propose and realize high-performance waveguide photodetectors based on bolometric/photoconductive effects by introducing an ultrathin wide silicon−graphene hybrid plasmonic waveguide,which enables efficient light absorption in graphene at 1.55μm and beyond.When operating at 2μm,the present photodetector has a responsivity of ~70 mA/W and a setup-limited 3 dB bandwidth of >20 GHz.When operating at 1.55μm,the present photodetector also works very well with a broad 3 dB bandwidth of >40 GHz(setup-limited)and a high responsivity of ~0.4 A/W even with a low bias voltage of−0.3 V.This work paves the way for achieving highresponsivity and high-speed silicon-graphene waveguide photodetection in the near/mid-infrared ranges,which has applications in optical communications,nonlinear photonics,and on-chip sensing.Jingshu Guo Jiang Li Chaoyue Liu Yanlong Yin Wenhui Wang Zhenhua Ni Zhilei Fu Hui Yu Yang Xu Yaocheng Shi Yungui Ma Shiming Gao Limin Tong Daoxin Dai 2020Light(Science & Applications)2020,9,1:10

4Blunted nitric oxide regulation in Tibetans under high-altitude hypoxia显示文摘Nitric oxide(NO) is an important molecule for vasomotor tone, and elevated NO signaling was previously hypothesized as a unique and adaptive physiological change in highland Tibetans. However, there has been lack of NO data from Tibetans living at low altitude and lowlander immigrants living at high altitude, which is crucial to test this hypothesis. Here, through cross-altitude(1990–5018 m) and cross-population(Tibetans and Han Chinese) analyses of serum NO metabolites(NOx) of 2086 individuals, we demonstrate that although Tibetans have a higher serum NOx level compared to lowlanders, Han Chinese immigrants living at high altitude show an even higher level than Tibetans. Consequently, our data contradict the previous proposal of increased NO signaling as the unique adaptive strategy in Tibetans.Instead, Tibetans have a relatively lower circulating NOx level at high altitude. This observation is further supported by data from the hypoxic experiments using human umbilical vein endothelial cells and gene knockout mice. No difference is detected between Tibetans and Han Chinese for endothelial nitric oxide synthase(e NOS), the key enzyme for circulating NO synthesis, suggesting that e NOS itself is unlikely to be the cause. We show that other NO synthesis-related genes(e.g. GCH1) carry Tibetan-enriched mutations significantly associated with the level of circulating NOx in Tibetans. Furthermore, gene network analysis revealed that the downregulation and upregulation of NOx is possibly achieved through distinct pathways.Collectively, our findings provide novel insights into the physiological and genetic mechanisms of the evolutionary adaptation of Tibetans to high-altitude hypoxia.Yaoxi He Xuebin Qi Ouzhuluobu Shiming Liu Jun Li Hui Zhang Baimakangzhuo Caijuan Bai Wangshan Zheng Yongbo Guo Duojizhuoma Baimayangji Dejiquzong Bianba Gonggalanzi Yongyue Pan Qula Kangmin Cirenyangji Wei Guo Yangla Yi Peng Xiaoming Zhang Kun Xiang Zhaohui Yang Liangbang Wang Gengdeng Yanfeng Zhang Tianyi Wu Bing Su Chaoying Cui 2018National Science Review2018,5,4:7
5De novo assembly of a Tibetan genome and identification of novel structural variants associated with high-altitude adaptation显示文摘Structural variants(SVs) may play important roles in human adaptation to extreme environments such as high altitude but have been under-investigated. Here, combining long-read sequencing with multiple scaffolding techniques, we assembled a high-quality Tibetan genome(ZF1), with a contig N50 length of 24.57 mega-base pairs(Mb) and a scaffold N50 length of 58.80 Mb. The ZF1 assembly filled 80 remaining N-gaps(0.25 Mb in total length) in the reference human genome(GRCh38). Markedly, we detected17 900 SVs, among which the ZF1-specific SVs are enriched in GTPase activity that is required for activation of the hypoxic pathway. Further population analysis uncovered a 163-bp intronic deletion in the MKL1 gene showing large divergence between highland Tibetans and lowland Han Chinese. This deletion is significantly associated with lower systolic pulmonary arterial pressure, one of the key adaptive physiological traits in Tibetans. Moreover, with the use of the high-quality de novo assembly, we observed a much higher rate of genome-wide archaic hominid(Altai Neanderthal and Denisovan) shared non-reference sequences in ZF1(1.32%–1.53%) compared to other East Asian genomes(0.70%–0.98%),reflecting a unique genomic composition of Tibetans. One such archaic hominid shared sequence-a662-bp intronic insertion in the SCUBE2 gene-is enriched and associated with better lung function(the FEV1/FVC ratio) in Tibetans. Collectively, we generated the first high-resolution Tibetan reference genome, and the identified SVs may serve as valuable resources for future evolutionary and medical studies.Ouzhuluobu Yaoxi He Haiyi Lou Chaoying Cui Lian Deng Yang Gao Wangshan Zheng Yongbo Guo Xiaoji Wang Zhilin Ning Jun Li Bin Li Caijuan Bai Baimakangzhuo Gonggalanzi Dejiquzong Bianba Duojizhuoma Shiming Liu Tianyi Wu Shuhua Xu Xuebin Qi Bing Su 2020National Science Review2020,7,2:4
6Selective adsorption of silver ions from aqueous solution using polystyrene-supported trimercaptotriazine resin显示文摘Trimercaptotriazine-functionalized polystyrene chelating resin was prepared and employed for the adsorption of Ag(I)from aqueous solution.The adsorbent was characterized according to the following techniques:Fourier transform infrared spectroscopy,elemental analysis,scanning electron microscopy and the Brunauer-Emmet-Teller method.The effects of initial Ag(I)concentration,contact time,solution pH and coexisting ions on the adsorption capacity of Ag(I)were systematically investigated.The maximum adsorption capacity of Ag(I)was up to 187.1 mg/g resin at pH 0.0 and room temperature.The kinetic experiments indicated that the adsorption rate of Ag(I)onto the chelating resin was quite fast in the first 60 min and reached adsorption equilibrium after 360min.The adsorption process can be well described by the pseudo second-order kinetic model and the equilibrium adsorption isotherm was closely fitted by the Langmuir model.Moreover,the chelating resin could selectively adsorb more Ag(I)ions than other heavy metal ions including:Cu(II),Zn(II),Ni(II),Pb(II)and Cr(III)during competitive adsorption in the binary metal species systems,which indicated that it was a highly selective adsorbent of Ag(I)from aqueous solution.Shiming Wang Hongling Li Xiaoya Chen Min Yang Yanxing Qi 2012Journal of Environmental Sciences2012,24,12:4
7Hearing Preservation in Acoustic Neuroma Surgery显示文摘Objective To report the authors’ experiences in hearing preservation during acoustic neuroma (AN) resection procedures. Methods Two cases of AN removal via retrosigmoid approach were reviewed. Hearing preservation was attempted in the aid of endoscopic technique along with continuous monitoring of the compound action potential (CAP) and auditory brainstem response(ABR) during the surgery. Results The tumor in Case 1 was 1.5 cm in diameter. The average pure-tone hearing threshold was 30 dB HL and ABR was normal. Waves I, III and V of ABR were present following tumor removal. At 7th month follow-up, audiometric thresholds and ABR inter-peak intervals had recovered to pre-operative levels, with normal facial nerve function. The patient in Case 2 had bilateral AN. The tumors measured 4.0 cm(left) and 5.0 cm (right) on MRI scans. The AN on the right side was removed first, followed by removal of the left AN four months later. Intraoperative CAP monitoring was employed during removal of the left AN. While efforts to preserve the cochlear nerve were not successful, CAPs were still present after tumor removal. Conclusions Intraoperatively recorded CAPs are not reliable in predicting postoperative hearing outcomes. In contrast, ABRs are an indicator of function of the peripheral auditory pathway. Presence of waves I, III and V following tumor removal may represent preservation of useful hearing.HAN Dongyi, YU Limei, YANG Shiming, YU LimingDepartment of Otolaryngology-Head and Neck Surgery, PLA General Hospital, Beijing 100853 2006Journal of Otology2006,1,1:4
8Hepatic encephalopathy complicated with hyponatremia and acid-base disturbance and its prognosis显示文摘Objective:To improve the diagnosis and therapeutic effect of occurrence and development of hyponatremia and disorder of acid-base balance among patients with hepatic encephalopathy(HE) by elucidating the regularity and mechanism,as well as its influence on prognosis.Methods:327 HE patients admitted to our hospital from January 1990 to June 2010 were enrolled.Meanwhile 316 patients hospitalized in the medical department of the same hospital were chosen as the control group.Patients in both groups were given the same methods to measure arterial blood gas parameters(pH value,PaCO2,[HCO3-],TCO2,BE and SaO2),blood biochemistry([Na+],[K+],[Cl-]),liver function,kidney function and blood glucose,serum sodium,and thereupon tocalculate the anion gap(AG) and the potential [HCO3-],and acid-base balance disorder.Results:Among the 327 HE patients,hyponatremia was found in 188 cases(57.4%),of whom 132 patients died(70.2%).While among the 316 patients in control group,68 presented with hyponatremia(21.5%),and 19 died(27.9%).The incidence and mortality were significantly different between the two groups(P<0.001).All the 327 patients presented with different degrees of acid-base balance disorder and 178 died(54.4%),in whom 164(50.2%) belonged to simple acid-base balance disorder and 74(45.1%) died,136(41.6%) were dual acid-base balance disorder and 80(58.8%) died,27(8.2%) were triple acid-base disturbance and 24(88.9%) died.Whereas in the control group only 83 patients(26.2%) were recognized as simple and dual acid-base balance disorder,and 18(21.7%) died.There was higher incidence of acid-base balance disorder and mortality rate in HE group than control one(P<0.001).Conclusion:Hyponatremia is valuable to judge HE patients' prognosis.The key parameters in the judgment and evaluation on acid-base balance disorder among HE patients are the change of pH values and serum electrolyte values.When pH value ≤ 7.30 or > 7.55,it generally suggests a poor prognosis.Ren Chengshan Wang Lei Zhao Xiaoyan Yang Shiming Zhang Yanqi Wang Xiwen Bo Jianying Zhang Pengbin Guo Hong Ling Xianlong Li Yihui Da Siping Xie Xia Ren Wei Li Chunhua Qian Guisheng 2012Journal of Medical Colleges of PLA(China)2012,27,3:3
9Viscosity and degradation controlled injectable hydrogel for esophageal endoscopic submucosal dissection显示文摘Endoscopic submucosal dissection(ESD)is a common procedure to treat early and precancerous gastrointestinal lesions.Via submucosal injection,a liquid cushion is created to lift and separate the lesion and malignant part from the muscular layer where the formed indispensable space is convenient for endoscopic incision.Saline is a most common submucosal injection liquid,but the formed liquid pad lasts only a short time,and thus repeated injections increase the potential risk of adverse events.Hydrogels with high osmotic pressure and high viscosity are used as an alternate;however,with some drawbacks such as tissue damage,excessive injection resistance,and high cost.Here,we reported a nature derived hydrogel of gelatin-oxidized alginate(G-OALG).Based on the rheological analysis and compare to commercial endoscopic mucosal resection(EMR)solution(0.25%hyaluronic acid,HA),a designed G-OALG hydrogel of desired concentration and composition showed higher performances in controllable gelation and injectability,higher viscosity and more stable structures.The G-OALG gel also showed lower propulsion resistance than 0.25%HA in the injection force assessment under standard endoscopic instruments,which eased the surgical operation.In addition,the G-OALG hydrogel showed good in vivo degradability biocompatibility.By comparing the results acquired via ESD to normal saline,the G-OALG shows great histocompatibility and excellent endoscopic injectability,and enables create a longer-lasting submucosal cushion.All the features have been confirmed in the living both pig and rat models.The G-OALG could be a promising submucosal injection agent for esophageal ESD.Chaoqiang Fan Kaige Xu Yu Huang Shuang Liu Tongchuan Wang Wei Wang Weichao Hu Lu Liu Malcolm Xing Shiming Yang 2021Bioactive Materials2021,6,4:3
10SCL-90 test results of the family members of patients with schizophrenia in China:a meta-analysis显示文摘Objective To evaluate the mental health status of family members of patients with schizophrenia in China.Methods Wan Fang,CNKI,VIP,CBM,Springer Link,Science Direct and Pub Med databases were searched to collect the relevant studies published prior to August 2016 that were about the psychological health status of the family members of patients with schizophrenia measured with the SCL-90 scale and Software Stata 11.0 was used for their meta-analysis.Results A total of 20 studies was included in this meta-analysis.Scores of somatization affection,obsessive-compulsive symptoms,interpersonal sensitivity,depression,anxiety,hostility,phobic anxiety,and paranoia ideation of the family members were significantly higher than those of general population norms in 2006(P<0.05).Scores of somatization affection,interpersonal sensitivity,depression,anxiety,hostility,phobic anxiety,paranoia ideation,and psychoticism of the family members were significantly higher than control group(P<0.05).Moreover,the difference was not statistically significant between male and female family members in mental health status(P>0.05).Conclusion Compared with the general population,psychological distress was more reported in the family members of patients with schizophrenia.There was no statistic significantly difference between male and female members.LI Shiming CAO Lingzhen CHEN Jia YANG Queping 2017国际精神病学杂志2017,44,6:3
11Identification of QTL for kernel number-related traits in a rice chromosome segment substitution line and fine mapping of qSP1显示文摘A chromosome segment substitution line (CSSL) is a powerful tool for combining quantitative trait locus (QTL) mapping with the pyramiding of desirable alleles. The rice CSSL Z1364 with increased kernel number was identified in a BC3F8 population derived from a cross of Nipponbare as the recipient with Xihui 18 as the donor parent. Z1364 carried three substitution segments distributed on chromosomes 1, 6, and 8. The mean substitution length was 1.19 Mb. Of 17 QTL identified on the substitution segments, qSP1 for spikelets per panicle, qSSD1 for seed-set density, and qNSB1 for number of secondary branches explained respectively 57.34%, 87.7%, and 49.44% of the corresponding phenotypic variance and were all linked to RM6777. Chi-square analysis showed that the increased kernel number in Z1364 was inherited recessively by a single gene. By fine mapping, qSP1 was delimited to a 50-kb region on the short arm of chromosome 1. Based on DNA sequence, a previously uncharacterized rice homolog of Arabidopsis thaliana AT4G32551 was identified as a candidate gene for qSP1 in which mutation increases the number of spikelets and kernels in Z1364. qSP1 was expressed in all tissues, but particularly in 1-cm panicles. The expression levels of OsMADS22, GN1A, and DST were upregulated and those of LAX2, GNP1, and GHD7 were downregulated in Nipponbare. These results provide a foundation for functional research on qSP1.Fuying Ma Xiaoyan Zhu Hui Wang Shiming Wang Guoqing Cui Ting Zhang Zhenglin Yang Guanghua He Yinghua Ling Nan Wang Fangming Zhao 2019The Crop Journal2019,7,4:3
12Cell junction proteins within the cochlea: A review of recent research显示文摘Cell-cell junctions in the cochlea are highly complex and well organized. The role of these junctions is to maintain structural and functional integrity of the cochlea. In this review, we describe classification of cell junction-associated proteins identified within the cochlea and provide a brief overview of the function of these proteins in adherent junctions, gap junctions and tight junctions.Bo Wang Bohua Hu Shiming Yang 2015Journal of Otology2015,10,4:2
13Hearing analysis in heterozygous and homozygous klotho gene deficient mice显示文摘Objective: To understand the crucial role of the klotho gene in hearing development in mouse models.Methods: PCR was used to identify CBA mice with different genotypes, i.e. WT, heterozygous(klotho +/-)or homozygous(klotho-/-). Mice phenotype and weight were recorded postnatal 25 days(P-25) and auditory brainstem responses(ABR) were used to determine auditory function at P-60.Results: klotho-/-mice tended to have smaller size, lighter weight and higher ABR thresholds at P-60,showing early onset age-related hearing loss(ARHL).Conclusion: Heterozygous and homozygous klotho deficient mice exhibit different degrees of hearing loss at young age, with homozygous mice(klotho-/-) showing more severe hearing loss. Our results indicate that persisted expression of klotho protein in the inner ear may potentially delay the onset of ARHL and play an important role in the protection of auditory function.Na Yuan Shiwei Qiu Qian Wang Wei Zhuang Guoping Li Tiantian Sun Shiming Yang Yuehua Qiao Xi Shi 2018Journal of Otology2018,13,4:2
14LOWER DOSE OF AMINOGLYCOSIDE OTOTOXIC EXPOSURE CAUSES PRESYNAPTIC ALTERATIONS ASSOICATED WITH HEARING LOSS显示文摘Objective To study presynaptic alternations of cochlear ribbons arising from aminoglycoside ototoxic stimuli in C57BL/6J mice. Methods Animals were injected with low dose gentamicin(100 mg/kg/day) for14 days, From the 14 th to 28 th days, the mice were maintained free of gentamicin treatment. Immunohistochemistry labeling was employed to trace RIBEYE, a major presynaptic componment of ribbon synapses.RIBEYE/CtBP2 expression levels were assessed and compared with hearing threshold shifts. Auditory function was assessed by auditory brainstem responses. The stereocilia of outer hair cells(OHCs) and IHCs was examined by scanning electron microscopy(SEM). Results Hearing thresholds were elevated with peak hearing loss observed on the 7th day after gentamicin exposure, followed by improvement after the 7th day.RIBEYE/CtBP2 expression directly correlated with observed hearing threshold shifts. Strikingly, we did not see any obvious changes in stereocilia in both OHCs and IHCs until the 28 th day. Mild changes in stereocilia were only observed in OHCs on the 28 th day. Conclusions These findings indicate that presynapse cochlear ribbons, rather than stereocilia, may be sensitive to aminoglycoside ototoxic exposure in mice cochleae. A pattern of RIBEYE/CtBP2 expression changes seems to parallel hearing threshold shifts and suggests presynaptic response properties to lower dosage of aminoglycoside ototoxic stimuli.LIU Ke WANG Xiaoyu LI Sijun TANG Siquan XU Yice WANG Xuefeng SUN Jianhe YANG Weiyan YANG Shiming 2014Journal of Otology2014,9,1:2
15Insights Into the Interfacial Degradation of High-Voltage All-Solid-State Lithium Batteries显示文摘Poly(ethylene oxide)(PEO)-based solid polymer electrolyte(SPE)is considered as a promising solid-state electrolyte for all-solid-state lithium batteries(ASSLBs).Nevertheless,the poor interfacial stability with high-voltage cathode materials(e.g.,LiCoO_(2))restricts its application in high energy density solid-state batteries.Herein,high-voltage stable Li_(3)AlF_(6) protective layer is coated on the surface of LiCoO_(2) particle to improve the performance and investigate the failure mechanism of PEO-based ASSLBs.The phase transition unveils that chemical redox reaction occurs between the highly reactive LiCoO_(2) surface and PEO-based SPE,resulting in structure collapse of LiCoO_(2),hence the poor cycle performance of PEO-based ASSLBs with LiCoO_(2) at charging voltage of 4.2 V vs Li/Li+.By sharp contrast,no obvious structure change can be found at the surface of Li_(3)AlF_(6)-coated LiCoO_(2),and the original layered phase was well retained.When the charging voltage reaches up to 4.5 V vs Li/Li+,the intensive electrochemical decomposition of PEO-based SPE occurs,leading to the constant increase of cell impedance and directly causing the poor performance.This work not only provides important supplement to the failure mechanism of PEO-based batter-ies with LiCoO_(2),but also presents a universal strategy to retain structure stability of cathode-electrolyte interface in high-voltage ASSLBs.Jiawen Li Yuchen Ji Haoran Song Shiming Chen Shouxiang Ding Bingkai Zhang Luyi Yang Yongli Song Feng Pan 2022Nano-Micro Letters2022,14,12:2
16Phenotypic similarities in pigs with SOX10^(c.321dupC)and SOX10^(c.325A>T)mutations implied the correlation of SOX10 haploinsufficiency with Waardenburg syndrome显示文摘SOX10 is a causative gene of Waardenburg syndrome(WS)that is a rare genetic disorder characterized by hearing loss and pigment disturbance.More than 100 mutations of SOX10 have been found in patients with Type 2 WS(WS2),Type 4 WS(WS4),and more complex syndromes.However,no mutation hotspot has been detected in SOX10,and most cases are sporadic,making it difficult to establish a correlation between the high phenotypic and genetic variability.In this study,a duplication of the 321th cytosine(c.321dupC)was introduced into SOX10 in pigs,which induced premature termination of the translation of SOX10(p.K108QfsX45).The premature stop codon in Exon 3 triggered the degradation of mutant mRNA through nonsense-mediated mRNA decay.However,SOX10^(c.321dupC) induced a highly similar phenotype of WS2 with heterogeneous inner ear malformation compared with its adjacent missense mutation SOX10^(c.325A>T).In addition,a site-saturation mutation analysis of the SOX10 N-terminal nuclear localization signal(n-NLS),where these two mutations located,revealed the correlation between SOX10 haploinsufficiency and WS by an in vitro reporter assay.The analysis combining the in vitro assay with clinical cases may provide a clue to clinical diagnoses.Tingting Lin Lihua Luo Weiwei Guo Wei Ren Chuanhong Liu Hong Wei Shiming Yang Yong Wang 2020Journal of Genetics and Genomics2020,47,12:2
17Olfactory and gustatory dysfunctions of COVID-19 patients in China:A multicenter study显示文摘Introduction:With the spread of the epidemic worldwide,an increasing number of doctors abroad have observed the following atypical symptoms of coronavirus disease 2019(COVID-19):olfactory or taste disorders.Therefore,clarifying the incidence and clinical characteristics of olfactory and taste disorders in Chinese COVID-19 patients is of great significance and urgency.Materials and Methods:A retrospective study was conducted,which included 229 severe acute respiratory syndrome coronavirus 2 confirmed patients,through face-to-face interviews and telephone follow-up.Following the completion of questionnaires,the patients participating in the study,were categorized according to the degree of olfactory and taste disorders experienced,and the proportion of each clinical type of patient with olfactory and taste disorders and the time when symptoms appeared were recorded.Results:Among the 229 patients,31(13.54%)had olfactory dysfunction,and 44(19.21%)had gustatory dysfunction.For the patients with olfactory dysfunction,6(19.35%)developed severe disease and became critically ill.Olfactory dysfunction appeared before the other symptoms in 21.43%of cases.The proportion of females with olfactory and gustatory dysfunction was higher than that of males(P<0.001).Conclusions:The incidence of olfactory and gustatory dysfunction was much lower than that reported abroad;the prognosis of patients with olfactory dysfunction is relatively favorable;olfactory and gustatory dysfunction can be used as a sign for early screening;females are more prone to olfactory and gustatory dysfunction.Jianhui Li Yi Sun Enqiang Qin Hu Yuan Mingbo Liu Wenqi Yi Zhu Chen Chengcheng Huang Fengjie Zhou Ruiyao Chen Leibo Zhang Ning Yu Qiong Liu Xuejun Zhou Jingjing He Boyu Li Fusheng Wang Changliang Yang Shiming Yang 2022World Journal of Otorhinolaryngology-Head and Neck Surgery2022,8,4:2
18Amniotic Membrane Transplantation for Conjunctival Tumor显示文摘Purpose: To evaluate the possibility of amniotic membrane transplantation (AMT) for the treatment of conjunctival tumor.Methods: Preserved AMT was performed in 26 patients (26 eyes) with conjunctival tumor, including 9 eyes (34.62%) with malignant tumor (conjunctival malignant melanoma,corneal and conjunctival squamous cell carcinoma, conjunctival lymphoma), 17 eyes(65.38%) with benign tumor(conjunctival papilloma, conjunctival dermoid tumor, conjunctival nevus, hemangioma etc.).Result: All the patients are followed up for 1 ~53 months. No acute rejection was observed after preserved AMT. Ideal healing was found in conjunctiva wound.Conclusion: Preserved AMT is a very effective method to repair wound after giant conjunctival tumor operation. Complete removal of tumor and perfect fixation are the key of ocular surface reconstruction.Zhicong Chen, Jianhua Yan, Huasheng Yang, Zhongyao Wu Youjian Pang, Shiming Ai, Yuxiang Mao Zhongshan Ophthalmic Center, Sun Yat-sen University, Guangzhou 510060, China 2003Eye Science2003,19,3:2
19Nitrogen addition and mowing alter drought resistance and recovery of grassland communities显示文摘Nitrogen enrichment and land use are known to influence various ecosystems,but how these anthropogenic changes influence community and ecosystem responses to disturbance remains poorly understood.Here we investigated the effects of increased nitrogen input and mowing on the resistance and recovery of temperate semiarid grassland experiencing a three-year drought.Nitrogen addition increased grassland biomass recovery but decreased structural recovery after drought,whereas annual mowing increased grassland biomass recovery and structural recovery but reduced structural resistance to drought.The treatment effects on community biomass/structural resistance and recovery were largely modulated by the stability of the dominant species and asynchronous dynamics among species,and the community biomass resistance and recovery were also greatly driven by the stability of grasses.Community biomass resistance/recovery in response to drought was positively associated with its corresponding structural stability.Our study provides important experimental evidence that both nitrogen addition and mowing could substantially change grassland stability in both functional and structural aspects.Our findings emphasize the need to study changes across levels of ecological organization for a more complete understanding of ecosystem responses to disturbances under widespread environmental changes.Zhuwen Xu Heyong Liu Yani Meng Jinfei Yin Haiyan Ren Mai-He Li Shan Yang Shiming Tang Yong Jiang Lin Jiang 2023Science China(Life Sciences)2023,66,7:2
