| 2 | Endothelial CDS2 deficiency causes VEGFA-mediated vascular regression and tumor inhibition显示文摘The response of endothelial cells to signaling stimulation is critical for vascular morphogenesis,homeostasis and function.Vascular endothelial growth factor-a(VEGFA)has been commonly recognized as a pro-angiogenic factor in vertebrate developmental,physiological and pathological conditions for decades.Here we report a novel finding that genetic ablation of CDP-diacylglycerol synthetase-2(CDS2),a metabolic enzyme that controls phosphoinositide recycling,switches the output of VEGFA signaling from promoting angiogenesis to unexpectedly inducing vessel regression.Live imaging analysis uncovered the presence of reverse migration of the angiogenic endothelium in cds2 mutant zebrafish upon VEGFA stimulation,and endothelium regression also occurred in postnatal retina and implanted tumor models in mice.In tumor models,CDS2 deficiency enhanced the level of tumorsecreted VEGFA,which in-turn trapped tumors into a VEGFA-induced vessel regression situation,leading to suppression of tumor growth.Mechanistically,VEGFA stimulation reduced phosphatidylinositol(4,5)-bisphosphate(PIP2)availability in the absence of CDS2-controlled-phosphoinositide metabolism,subsequently causing phosphatidylinositol(3,4,5)-triphosphate(PIP3)deficiency and F0X01 activation to trigger regression of CDS2-null endothelium.Thus,our data indicate that the effect of VEGFA on vasculature is context-dependent and can be converted from angiogenesis to vascular regression. | Wencao Zhao Le Cao Hanru Ying Wenjuan Zhang Dantong Li Xiaolong Ziiu Wenzhi Xue Shuang Wu Mengye Cao Cong Fu Haonan Qi Yimei Hao Yun-Chi Tang Jun Qin Tao PZhong Xiaoxi Lin Luyang Yu Xuri Li Lin Li Dianqing Wu Weijun Pan | 2019 | Cell Research2019，29，11： | 9 |
| 3 | Intelligent identification of two-dimensional nanostructures by machine-learning optical microscopy显示文摘Two-dimensional (2D)materials and their heterostructures,with wafer-scale synthesis methods and fascinating properties,have attracted significant interest and triggered revolutions in corresponding device applications.However,facile methods to realize accurate,intelligent,and large-area characterizations of these 2D nanostructures are still highly desired.Herein,we report the successful application of machine-learning strategy in the optical identification of 2D nanostructures.The machine-leaming optical identification (MOI)method endows optical microscopy with intelligent insight into the characteristic color information of 2D nanostructures in the optical photograph.The experimental results indicate that the MOI method enables accurate,intelligent,and large-area characterizations of graphene,molybdenum disulfide,and their heterostructures, including identifications of the thickness,existence of impurities,and even stacking order.With the convergence of artificial intelligence and nanoscience,this intelligent identification method can certainly promote fundamental research and wafer-scale device applications of 2D nanostructures. | Xiaoyang Lin Zhizhong Si Wenzhi Fu Jianlei Yang Side Guo Yuan Cao Jin Zhang Xinhe Wang Peng Liu Kaili Jiang Weisheng Zhao | 2018 | Nano Research2018，11，12： | 5 |
| 4 | YTHDF2 is essential for spermatogenesis and fertility by mediating a wave of transcriptional transition in spermatogenic cells显示文摘The dynamic and reversible regulation roles of m^(6)A modification and the characterization of m^(6)A readers have provided new insights into spermatogenesis at the post-transcriptional level.YTHDF2,as an m^(6)A reader,has been reported to mediate the m^(6)A-containing transcript decay during the mouse oocyte maturation,embryonic stem cell differentiation,neural development,and zebrafish maternal-to-zygotic transition.However,the roles of YTHDF2 in mammalian spermatogenesis are uncertain.Here,we generated germ cell-specific Ythdf2 mutants(Ythdf2-vKO)at a C57BL/6J background and demonstrated that YTHDF2 is essential for mouse spermatogenesis and fertility.Ythdf2-vKO provides oligoasthenoteratozoospermia phenotype with increased apoptosis in germ cells.High-throughput RNA-seq analysis showed that a group of mRNAs is upregulated in Ythdf2-vKO mouse testis;further analysis and MeRIP-qPCR data showed that most of the upregulated genes in Ythdf2-vKO mouse testis are modified with m^(6)A and are YTHDF2 candidate binding genes.Interestingly,RNA-seq analysis combined with our previous single-cell transcriptomics data of mouse spermatogenesis pointed out the failure of a wave of transcript transition during the spermatogenesis of Ythdf2-vKO mice,which was confirmed by gene expression analysis using qPCR of diplotene spermatocytes and round spermatids obtained through fluorescence-activated cell sorting.Our study demonstrates the fundamental role of YTHDF2 during mouse spermatogenesis and provides a potential candidate for the diagnosis of male infertility with the oligoasthenoteratozoospermia syndrome. | Xinxi Zhao Zhen Lin Yong Fan Wenzhi Li Yujie Zhang Fei Li Tong Hong Hua Feng Minghan Tong Ningling Wang Yanping Kuang Qifeng Lyu | 2021 | Acta Biochimica et Biophysica Sinica2021，53，12： | 2 |
| 5 | Two Ultraviolet Radiation Datasets that Cover China显示文摘Ultraviolet(UV) radiation has significant effects on ecosystems, environments, and human health, as well as atmospheric processes and climate change. Two ultraviolet radiation datasets are described in this paper. One contains hourly observations of UV radiation measured at 40 Chinese Ecosystem Research Network stations from 2005 to 2015. CUV3 broadband radiometers were used to observe the UV radiation, with an accuracy of 5%, which meets the World Meteorology Organization's measurement standards. The extremum method was used to control the quality of the measured datasets. The other dataset contains daily cumulative UV radiation estimates that were calculated using an all-sky estimation model combined with a hybrid model. The reconstructed daily UV radiation data span from 1961 to 2014. The mean absolute bias error and root-mean-square error are smaller than 30% at most stations, and most of the mean bias error values are negative, which indicates underestimation of the UV radiation intensity. These datasets can improve our basic knowledge of the spatial and temporal variations in UV radiation. Additionally, these datasets can be used in studies of potential ozone formation and atmospheric oxidation, as well as simulations of ecological processes. | Hui LIU Bo HU Yuesi WANG Guangren LIU Liqin TANG Dongsheng JI Yongfei BAI Weikai BAO Xin CHEN Yunming CHEN Weixin DING Xiaozeng HAN Fei HE Hui HUANG Zhenying HUANG Xinrong LI Yan LI Wenzhao LIU Luxiang LIN Zhu OUYANG Boqiang QIN Weijun SHEN Yanjun SHEN Hongxin SU Changchun SONG Bo SUN Song SUN Anzhi WANG Genxu WANG Huimin WANG Silong WANG Youshao WANG Wenxue WEI Ping XIE Zongqiang XIE Xiaoyuan YAN Fanjiang ZENG Fawei ZHANG Yangjian ZHANG Yiping ZHANG Chengyi ZHAO Wenzhi ZHAO Xueyong ZHAO Guoyi ZHOU Bo ZHU | 2017 | Advances in Atmospheric Sciences2017，34，7： | 2 |
| 6 | Quantification of SARS-CoV-2 antigen levels in the blood of patients with COVID-19显示文摘Dear Editor,Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)has caused the global outbreak of coronavirus disease 2019(COVID-19).By far,more than 35 million people had been infected by SARS-CoV-2,resulting in more than 1 million deaths globally.It is well recognized that SARSCoV-2 preferentially attacks pulmonary epithelial cells,leading to acute respiratory distress syndrome(ARDS). | Bin Su Jiming Yin Xingguang Lin Tiantian Zhang Xiao Yao Ying Xu Yao Lu Wenzhi Wang Kun Liu Jie Zhang Liangzhi Xie Ronghua Jin Yingmei Feng | 2021 | Science China(Life Sciences)2021，64，7： | 2 |
| 7 | Wafer-scale patterned growth of type-II Dirac semimetal platinum ditelluride for sensitive room-temperature terahertz photodetection显示文摘As the lastly unexplored electromagnetic wave,terahertz(THz)radiation has been exploited in a plenty of contexts such as fundamental research,military and civil fields.Most recently,representative two-dimensional(2D)topological semimetal,platinum ditelluride(PtTe_(2))has attracted considerable research interest in THz detection due to its unique physical properties.However,to achieve practical applications,the low-cost,large-scale,controllable synthesis and efficient patterning of 2D materials are key requirements,which remain a challenge for PtTe_(2)and its photodetectors(PDs).Herein,a facile approach is developed to obtain waferscale(2-inches)patterned PtTe_(2)arrays using one-step tellurium-vapor transformation method and micro-Nano technology.PtTe_(2)PD arrays are fabricated with the as-grown PtTe_(2)arrays evenly distributed on a 2-inch wafer,exhibiting high conductivity(~2.7×105 S m^(-1))and good electrical consistency.Driven by the Dirac fermions,PtTe_(2)PDs achieve a broadband(0.02-0.3 THz)response with a fast response speed(~4.7μs),a high sensitivity(~47 pW Hz^(-1/2))and high-resolution transmission THz-imaging capability,which displays the potential of large-area THz array imaging.These results are one step towards the practical applications of integrated PD arrays based on 2D materials. | Zhuo Dong Wenzhi Yu Libo Zhang Liu Yang Luyi Huang Yan Zhang Zeqian Ren Haoran Mu Cheng Chen Junrong Zhang Jie Li Lin Wang Kai Zhang | 2023 | InfoMat2023，5，5： | 1 |

| 10 | Microbial diversity and structure in the gastrointestinal tracts of two stranded short-finned pilot whales(Globicephala macrorhynchus)and a pygmy sperm whale(Kogia breviceps)显示文摘Information on the gut microbiome composition of different mammals could provide novel insights into the evolution of mammals and succession of microbial communities in different hosts.However,there is limited information on the gut microbiome composition of marine mammals,especially cetaceans because of sampling constraints.In this study,we investigated the diversity and composition of microbial communities in the stomach,midgut,and hindgut of 2 stranded short-finned pilot whales(Globicephala macrorhynchus)and hindgut of a stranded pygmy sperm whale(Kogia breviceps)by using 16S rRNA gene amplicon sequencing technology.On the basis of the 50 most abundant operational taxonomic units,principal coordinate analysis,and non-metric multidimensional scaling analysis,we confirmed that the gut microbial communities of the 3 whales were different.Our results revealed that the gut microbiome of 1 stranded short-finned pilot whale GM16 was dominated by Firmicutes(mainly Clostridium)and Fusobacteria;whereas that of the other pilot whale GM19 was composed of Gammaproteobacteria and Bacteroidetes(mainly Vibrio and Bacteroides,respectively),probably caused by intestinal disease and antibiotic treatment.The gut microbiome of the pygmy sperm whale was dominated by Firmicutes and Bacteroidetes.Moreover,different gastrointestinal tract regions harbored different microbial community structures.To our knowledge,this is the first report of the gut microbiome of short-finned pilot whales,and our findings will expand our current knowledge on microbial diversity and composition in the gastrointestinal tract of cetaceans. | Shijie BAI Peijun ZHANG Mingli LIN Wenzhi LIN Zixin YANG Songhai LI | 2021 | Integrative Zoology2021，16，3： | 1 |
| 11 | Comparison of the Macrozoobenthic Community and Sedimentary Environment with and Without Horseshoe Crab Presence in the Crocodile Island Intertidal Zone,Xiamen,China显示文摘In order to compare the macrozoobenthic community and sedimentary environment with and without the presence of horseshoe crabs,the benthic macrofauna,sediment grain size,chromium(Cr),cobalt(Co),nickel(Ni),polycyclic aromatic hydrocarbon(PAHs),organic carbon and nitrogen were seasonally investigated at site A(with horseshoe crab presence),sites B and C(without horseshoe crab presence)in the Crocodile Island intertidal zone in Xiamen from June 2018 to July 2019.The results showed that most of the community parameters of benthic macrofauna,population parameters of common benthic macrofauna and environmental parameters were significantly different at the sites with horseshoe crab versus non-horseshoe crab sites.A two-way ANOVA test showed that the densities of Ceratonereis erythraeensis and Sigambra hanaokai had significant site variation.Cluster and nonmetric multi-dimensional scaling(NMDS)analysis showed the community composition of benthic macrofauna was significantly different among the three sampling sites over four seasons.The mean sand content at site A(64.32%)was higher than those at site B(36.01%)and site C(18.86%).Conversely,the mean contents of silt,clay,Cr,Co,Ni,organic carbon,organic nitrogen,phenanthrene,and pyrene at site A were lower than those at site B and site C.These observations are consistent with the expected preferences of horseshoe crabs to live in areas with 60%sand content,which is associated with abundant and edible clamworms in the Crocodile Island intertidal zone,Xiamen. | CAI Lizhe ZHAO Xiaoyu PENG Wenqing LIN Jingxiang YANG Deyuan RAO Yiyong FU Sujing CHEN Xinwei CAO Wenzhi | 2022 | Journal of Ocean University of China2022，21，3： | 1 |
| 12 | Interface and surface engineering of black phosphorus: a review for optoelectronic and photonic applications显示文摘Since being rediscovered as an emerging 2D material,black phosphorus(BP),with an extraordinary energy structure and unusually strong interlayer interactions,offers new opportunities for optoelectronics and photonics.However,due to the thin atomic body and the ease of degradation with water and oxides,BP is highly sensitive to the surrounding environment.Therefore,high-quality engineering of interfaces and surfaces plays an essential role in BP-based applications.In this review,begun with a review of properties of BP,different strategies of interface and surfaces engineering for high ON-OFF ratio,enhanced optical absorption,and fast optical response are reviewed and highlighted,and recent state-of-the-art advances on optoelectronic and photonic devices are demonstrated.Finally,the opportunities and challenges for future BP-related research are considered. | Haoran Mu Wenzhi Yu Jian Yuan Shenghuang Lin Guangyu Zhang | 2022 | Materials Futures2022，1，1： | 0 |
| 13 | A pioneering survey of deep-diving and off-shore cetaceans in the northern South China Sea显示文摘A pioneering boat-based survey was conducted in 2019,to gather baseline information regarding the presence,composition,relative abundance,and spatial distribution of deep-diving and off-shore cetaceans in the northern South China Sea(SCS).A total of 27 sightings comprising at least 8 cetacean species were recorded during the 13-day survey,including 5 deep-diving species(i.e.Risso’s dolphin[Grampus griseus],short-finned pilot whale[Globicephala macrorhynchus],sperm whale[Physeter macrocephalus],Cuvier’s beaked whale[Ziphius cavirostris],and an unidentified beaked whale[either the ginkgo-toothed beaked whale,Mesoplodon ginkgodens,or Deraniyagala’s beaked whale,Mesoplodon hotaula]),as well as 3 off-shore dolphins(i.e.pantropical spotted dolphin[Stenella attenuate],striped dolphin[Stenella coeruleoalba],and Fraser’s dolphin[Lagenodelphis hosei]).With the exception of pantropical spotted dolphins,all other species were sighted and recorded at sea in the northern SCS for the first time.The pantropical spotted dolphin was the most frequently sighted species,comprising 30%of the total sightings.Deep-diving cetaceans were mainly sighted in the northern Xisha Archipelago,whereas off-shore dolphins were distributed across the survey area.The pantropical spotted dolphin was observed in aggregations of more than 100 individuals and nearly all encountered species included calves;these findings suggested that the survey area functions as an important feeding and calving ground for various cetacean species.This pioneering survey provides fundamental information regarding cetacean fauna in the northern SCS and highlights the need to strengthen research and conservation efforts concerning these species. | Mingli LIN Mingming LIU Francesco CARUSO Massimiliano ROSSO Xiaoming TANG Lijun DONG Wenzhi LIN Anna BORRONI Alessandro BOCCONCELLI Liang DAI Songhai LI | 2021 | Integrative Zoology2021，16，4： | 0 |
| 14 | First live sighting of Deraniyagala’s beaked whale(Mesoplodon hotaula)or ginkgo-toothed beaked whale(Mesoplodon ginkgodens)in the western Pacific(South China Sea)with preliminary data on coloration,natural markings,and surfacing patterns显示文摘Beaked whales represent around 25%of known extant cetacean species,yet they are the least known of all marine mammals.Identification of many Mesoplodon species has relied on examination of a few stranded individuals.Particularly,the ginkgo-toothed beaked whale(Mesoplodon ginkgodens)and Deraniyagala’s beaked whale(Mesoplodon hotaula)are among the least-known of beaked whale species,without confirmed sightings of living individuals to date.We present a sighting of 3 free-ranging individuals of M.ginkgodens/hotaula whale from a dedicated marine mammal vessel survey carried out in the South China Sea in April and May 2019.Photographic data(301 photographs)from the sighting were compared to photos of fresh stranded ginkgo-toothed beaked whale and Deraniyagala’s beaked whale from both historical and unpublished records.We found that free-ranging M.ginkgodens and M.hotaula individuals can be easily distinguished from other Mesoplodon species due to differences in melon and gape shapes and coloration patterns.However,accurate at-sea differentiation of M.ginkgodens and M.hotaula may not be possible due to high similarity in both coloration and scarring patterns.In addition to our photo-identification data,we collected what we believe to be the first preliminary descriptions of surfacing behavior and diving patterns of one of these species.Finally,the presence of scars possibly caused by fishing gear or marine litter raises concerns about anthropogenic impacts and conservation of these poorly known species. | Massimiliano ROSSO Mingli LIN Francesco CARUSO Mingming LIU Lijun DONG Anna BORRONI Wenzhi LIN Xiaoming TANG Alessandro BOCCONCELLI Songhai LI | 2021 | Integrative Zoology2021，16，4： | 0 |
| 15 | Cetacean occurrence and diversity in whale-watching waters off Mirissa,Southern Sri Lanka显示文摘Scientific information is vital to the conservation of cetaceans and the management of whale-watching activities.The southern coastal waters of Sri Lanka are near a narrow continental shelf and biologically abundant in cetacean species.Although the occurrence of cetaceans has been investigated in certain waters of Sri Lanka,few surveys have been conducted along the southern coast.To fill this gap,we conducted boat-based surveys from January to May 2017 to investigate the occurrence,diversity,and behavior of cetaceans in the waters off Mirissa,covering a survey area of 788.9 km2.During 55 survey days,we recorded a total of 242 cetacean sightings and identified at least 9 species(3 mysticetes and 6 odontocetes).The blue whale was the most common mysticete species(167 of 174 mysticete encounters),followed by the Omura’s whale(4 of 174)and Bryde’s whale(3 of 174).The spinner dolphin was the most common odontocete species(28 of 68 odontocete encounters),followed by the sperm whale(18 of 68),common bottlenose dolphin(13 of 68),short-finned pilot whale(5 of 68),melon-headed whale(2 of 68),and killer whale.Blue whales and sperm whales exhibited a clear preference for outer shelf and high slope areas,and blue whales were observed feeding along these waters.The present study provides near-baseline information on cetacean occurrence and diversity in whale-watching waters off southern Sri Lanka,and highlights the urgent need for proper management strategies for whale-watching activities. | Dissanayake Mudiyanselage Rajitha SANKALPA Elle Pathirathnalage Darshana Nuwan THILAKARATHNE Wenzhi LIN Vidusanka THILAKANAYAKA Chathurika Piumi KUMARASINGHE Mingming LIU Mingli LIN Songhai LI | 2021 | Integrative Zoology2021，16，4： | 0 |
| 16 | Prey decline leads to diet shift in the largest population of Indo-Pacific humpback dolphins?显示文摘The Pearl River Delta(PRD)region on the southeast coast of China has long been known as a highly productive fishing ground.Since the late 1980s,fishing pressure in the PRD has been intense,which warrants concerns of potential fishery-related impacts on the food resources and foraging ecology of apex marine predators in this region,such as the Indo-Pacific humpback dolphin(Sousa chinensis).In this study,we examined 54 stomachs with food remains,collected from beached carcasses of humpback dolphins recovered during fifteen years between 2003 and 2017.The 6043 identified prey items represent 62 teleost taxa,primarily small estuarine fish,but also larger reef fish.The dolphins appear to be opportunistic foragers,hunting across the water-column,with preference for shoaling and meaty fishes(e.g.Collichthys lucidus IRI%=38.6%,Johnius belangerii IRI%=23.1%,Mugil cephalus IRI%=14.0%).Our findings suggest a dietary shift in recent years,from primarily demersal(as previously reported)to greater intake of neritic and pelagic fish.Dolphin foraging group size has decreased in recent years,which corresponds with declining size and numbers of prey items retrieved from dolphin stomachs.We suggest that these are indicators of declining food resources.Faced with a shortage of preferred prey,humpback dolphins may have broadened their dietary spectrum to maintain their daily energy intake,while their foraging group size decreased in response to the altered tradeoff between the costs and benefits of group foraging. | Wenzhi LIN Leszek KARCZMARSKI Ruilian ZHOU Yaqian MO Lang GUO Sam King Fung YIU Xi NING Tak-Cheung WAI Yuping WU | 2021 | Integrative Zoology2021，16，4： | 0 |
| 17 | Photo-identification comparison of four Indo-Pacific humpback dolphin populations off southeast China显示文摘Indo-Pacific humpback dolphins(Sousa chinensis)inhabit shallow coastal waters of the Indo-Pacific region including southeast China,with at least 6 putative populations identified to date in Chinese waters.However,the connectivity among these populations has not yet been fully investigated.In the present study,we compared and crossmatched photographic catalogs of individual dolphins collected to date in the Pearl River Delta region,Leizhou Bay,Sanniang Bay,and waters southwest of Hainan Island,a total of 3158 individuals,and found no re-sighting of individual dolphins among the 4 study areas.Furthermore,there was a notable difference in the pigmentation pattern displayed by individuals from these 4 regions.We suggest that this may be a phenotypical expression of fine-scale regional differentiation among humpback dolphin groups,possibly distinct populations.Given the considerable conservation management implications it may carry(e.g.definition of management units),further research is much needed. | Xiaoming TANG Wenzhi LIN Leszek KARCZMARSKI Mingli LIN Stephen C.Y.CHAN Mingming LIU Tianfei XUE Yuping WU Peijun ZHANG Songhai LI | 2021 | Integrative Zoology2021，16，4： | 0 |
| 18 | Early divergence and differential population histories of the Indo-Pacific humpback dolphin in the Pacific and Indian Oceans显示文摘The currently recognized Indo-Pacific humpback dolphin occurs in estuaries and surrounding shallow waters from the South China Sea to the Asian coast of the Indian Ocean.However,a recent study suggested that the humpback dolphin from the Bay of Bengal may represent a distinct phylogenetic species.In this study,we sequenced 915-bp mtDNA segments from five geographic populations in both Chinese and Thai waters;together with previously published sequences,these data revealed that the ancestral Indo-Pacific humpback dolphin might have split during the transition from the Oligocene to Miocene(23.45 Mya,95%HPD:16.65–26.55 Mya),and then dispersed along the Pacific and Indian Ocean coasts of Asia.Genetic differentiation was detected between most of the examined populations,except for only a few pairwise populations in the northern South China Sea.Genetic differentiation/distance between the humpback dolphins from the northern and southern South China Sea met the sub-species threshold value proposed for marine mammals,whereas that between the humpback dolphins in the Pacific and the Indian Ocean was above the species threshold.Bayesian inference of historic gene flow indicated low but constant northward gene flow along the Indian Ocean coast;however,there was a recent abrupt increase in gene flow in the Pacific region,likely due to the shortening coastline at the low stand of sea level.Our results revealed that the current taxonomic classification of Indo-Pacific humpback dolphins may not reflect their phylogeography. | Liyuan ZHAO Watchara SAKORNWIMON Wenzhi LIN Peijun ZHANG Rachawadee CHANTRA Yufei DAI Reyilamu AIERKEN Fuxing WU Songhai LI Kongkiat KITTIWATTANAWONG Xianyan WANG | 2021 | Integrative Zoology2021，16，4： | 0 |
| 19 | Soil-moisture dynamics and tree-water status in a Picea crassifolia forest, Qilian Mountains, China显示文摘Landscapes of the mountainous regions in northwestern China comprise a unique pattern of vegetation,consisting of a mosaic of grassland and shrub-forest.Forests generally self-organize into ordered structures and coalesce into blocks on north-facing slopes or stripes along southeast-facing slopes,with Picea crassifolia being the most representative and dominant tree species.We investigated the tree-water status and soil-moisture dynamics at a forest site(Guantan)of the Qilian Mountains in northwest China.The 30-minute-interval measurements of tree-sap flow during the growing season of 2008 are presented,and the potential functional relations between tree transpiration and environmental factors are evaluated.Soil moisture and solar energy were identified as the most influential factors,explaining more than 70%of the variance in sap flow.Based on field measurements obtained at the forest site,a stochastic model of soil-moisture dynamics was tested;and the steady-state probability density functions(PDFs)of the long-term soil-moisture dynamics and static tree-water stress were estimated using the validated model and parameters.We found that the model reproduced measured soil moisture well,despite all the simplifying assumptions.The generated PDF of long-term soil moisture was relatively open,with middle to low average values;and the calculated density of the static tree-water stress at the forest site was largely concentrated between 0 and 0.6,suggesting a moderate water-stress situation in most cases.We argue that both water and energy are limiting factors for vegetation at the forest site.In addition,the tradeoff between reduced evapotranspiration(ET)from limited solar energy and increased soil-moisture availability may create a stressed but tolerable environment and,in turn,produce a relatively constant ecological niche favorable to Picea crassifolia growth. | Hu Liu Lin Li SiJia Wang QiYue Yang WenZhi Zhao | 2020 | Research in Cold and Arid Regions2020，12，1： | 0 |
| 20 | Mapping the fishing intensity in the coastal waters off Guangdong province, China through AIS data显示文摘Fishing activities result in a depletion of fish resources and an increase in bycatch probability of non-target species,which are thought to be the cause of the recent demographic change experienced by coastal cetaceans in waters off Guangdong province,China.However,fishing intensity and its spatiotemporal pattern remain poorly examined in this region.Here,random daily tracks from 100 fishing vessels were used to estimate fishing operations in the coastal waters off Guangdong province.The performance of two methods was tested with Automatic Identification System(AIS)data collected in the Pearl River Delta region(PRD).This assessment found that the Density-Based Spatial Clustering of Applications with Noise(DBSCAN)could falsely identify port regions as fishing grounds,while the speed-based method provided a more accurate estimate of fishing grounds with less computational effort.Subsequently,the spatiotemporal pattern of fishing intensity in the coastal waters off the entire Guangdong province was examined with the speed-based method.Our results showed that 87.75%of the coastal fishing activities occurred in waters<40 m in depth.The method detected two spatially heterogeneous fishing grounds extending from the PRD to either the west or east sides of Guangdong province.In the west fishing ground,43.4%of fishing vessels operated in the waters off Yangjiang city;while in the east fishing ground,fishing activities were more evenly distributed.The present study suggests that the AIS is able to provide high-resolution data to monitor the development of fishing activities,which may be useful for informing marine resource management and spatial planning. | Shenglan Chen Wenzhi Lin Chen Zeng Binshuai Liu Agathe Serres Songhai Li | 2023 | Water Biology and Security2023，2，1： | 0 |
