To understand plant invasions this study aims to test which of the two plant invasiveness hypotheses; ‘low native diversity' vs. ‘high native diversity', is supported by the regional distribution patterns of invasive plant species in the Himalayas,Nepal. This study is based on data retrieved from published literatures and herbarium specimens. The relationship between invasive plant species distribution patterns and that of native plant species is elucidated by scatter plots, as well as by generalized linear models. The native plant species and invasive plant species have similar distribution patterns and the maximum number of invasive plant species is found in the same altitudinal range where the highest richness for native tree species is found. There is a clear trend of higher invasive plant richness in regions where native tree species richness is relatively high.Consequently, the native plant richness is highest in the central phytogeographic region, followed by the eastern and the western regions, respectively. The invasive plant species also follows a similar trend.Additionally, the invasive plant species richness was positively correlated with anthropogenic factors such as human population density and the number of visiting tourists. This study supports the hypothesis that ‘high native diversity' supports or facilitates invasive plant species. Further, it indicates that nativeand invasive plant species may require similar natural conditions, but that the invasive plant species seem more dependent and influenced by anthropogenic disturbance factors.展开更多

文摘Alien species from the Asteraceae family frequently invade native plant communities.This study aims to determine how the number of Asteraceae species(i.e.,Erigeron canadensis,E.annuus,and Solidago canadensis)in a co-invasion affects plant taxonomic diversity and invasibility in plant communities in China.We found that co-invasions by one or two Asteraceae species decreased plant diversity and increased community invasibility.However,co-invasion by three Asteraceae species increased plant diversity and community invasibility.We also found that plant taxonomic diversity was negatively correlated with total coverage of invasive Asteraceae species.Conversely,community invasibility was positively correlated with total coverage of invasive Asteraceae species.These findings indicate that the number of Asteraceae invasive species positively correlates with total coverage,diversity,dominance,evenness,and invasibility.Our study shows that co-invasion by three IAS may increase plant taxonomic diversity but also community invasibility,which may further facilitate subsequent invasion.

文摘Invasive plant species are exerting a serious threat to biological diversity in many regions of the world. To understand plant invasions this study aims to test which of the two plant invasiveness hypotheses; ‘low native diversity' vs. ‘high native diversity', is supported by the regional distribution patterns of invasive plant species in the Himalayas,Nepal. This study is based on data retrieved from published literatures and herbarium specimens. The relationship between invasive plant species distribution patterns and that of native plant species is elucidated by scatter plots, as well as by generalized linear models. The native plant species and invasive plant species have similar distribution patterns and the maximum number of invasive plant species is found in the same altitudinal range where the highest richness for native tree species is found. There is a clear trend of higher invasive plant richness in regions where native tree species richness is relatively high.Consequently, the native plant richness is highest in the central phytogeographic region, followed by the eastern and the western regions, respectively. The invasive plant species also follows a similar trend.Additionally, the invasive plant species richness was positively correlated with anthropogenic factors such as human population density and the number of visiting tourists. This study supports the hypothesis that ‘high native diversity' supports or facilitates invasive plant species. Further, it indicates that nativeand invasive plant species may require similar natural conditions, but that the invasive plant species seem more dependent and influenced by anthropogenic disturbance factors.

文摘Rapid colonization by invasive plants threatened local biodiversity worldwide;however,their distributional hotspots and future habitat shifts remain poorly understood in developing nations such as Nigeria.Using MaxEnt model,we investigated present and future habitat suitability for two aggressive invaders,C.odorata and T.diversifolia,across Nigeria's urban landscapes.We used a dataset consisting of 327 and 108 occurrence points for C.odorata and T.diversifolia,respectively,along with twenty-three(23)environmental variables to identify occurrence and areas of concern under current climatic fluctuations.The results revealed that the model performed strongly(AUC>0.85)and identified precipitation seasonality as the dominant predictor for both species.The finding indicates that precipitation seasonality of≤59 CV,isothermality of≥57%and precipitation of wettest month of≥170 mm enhance niche occupancy of C.odorata,while precipitation seasonality of 62-70 CV,precipitation of wettest quarter and maximum temperature of warmest month of≥450 mm and 35℃,respectively enhance that of T.differsifolia.Current predictions place C.odorata primarily along the southern coast,while T.diversifolia is most suitable in the southwest and extends into the northcentral.Future suitable area for C.odorata will slightly expand by 2050 and 2070,encroaching into southeastern and some central states.In contrast,T.diversifolia contracts under CNRM-CM5 but shows a modest expansion under GFDL-CM3.These projections indicate that climate change may reinforce the dominance of C.odorata in southern Nigeria,whereas T.differsifolia may exhibit divergent trajectories from southern to certain northern states in the future.

文摘The competitor,stress tolerator,and ruderal strategy(CSR)framework has been widely applied to explain ecological processes across species.However,its utility in revealing intra-specific trade-offs and genetic adaptation to climate remains unclear.In this study,we examined whether the CSR strategy estimated by leaf traits can identify adaptations to climate in the common reed Phragmites australis.For this purpose,we integrated functional trait data from field surveys and a three-year common garden experiment to compare CSR scores between two typical populations of P.australis from western and eastern China.We further assessed the associations of CSR scores with latitude,bioclimatic factors,and phylogeographical sources using a global dataset including two invaded lineages in the North America.We found that competitor scores were positively correlated with latitude,whereas stress tolerator scores were negatively correlated.Competitor scores were positively correlated with bioclimatic factors,even when controlling for phylogeny.All CSR scores displayed significant phylogenetic signals,with the invasive lineage in the higher latitudes(haplotype M)exhibiting higher stress tolerator scores than the native lineage.Differences in competitor and stress tolerator scores between western and eastern Chinese populations of P.australis were consistent across field and common garden experiments.Although intra-species variation in CSR strategy may be influenced by phylogenetic history,our finding that CSR strategy in P.australis populations is correlated with latitude suggests these plants have adapted to local climates along a latitudinal gradient.

文摘Over the past 160 years,shrubs have expanded globally,significantly altering native ecosystem structures,functions,and services.However,a comprehensive bibliometric perspective on shrub encroachment remains underdeveloped,and a holistic research framework is lacking to understand the evolution,current state,and emerging research frontiers.To address this,we conducted a bibliometric analysis and literature review using the R software package,based on the Web of Science Core Collection citation database.Keyword analysis revealed that research has focused on various grassland types,soil nutrients,climate change,and plant communities.Thematic mapping identified key themes,including influencing factors,feedback mechanisms,invasion processes,ecological consequences,shrub management,and quantitative monitoring.Basic themes encompass shrub encroachment,dynamics,fire,grazing,and climate change while emerging themes include decomposition,microbial biomass,and ecosystem function.We synthesized eight key factors driving shrub encroachment:atmospheric CO_(2)concentration,global warming,changes in rainfall patterns,atmospheric nitrogen deposition,topography,soils,herbivory,fire suppression,and land use change.The feedback mechanisms of shrub encroachment,driven by exogenous and maintained by endogenous factors,were categorized into three stages:seed dispersal,colonizing and establishment,and diffusion.Shrub encroachment also impacts ecosystem services,including provisioning(e.g.,forage productivity),regulating(e.g.,hydrological regulation),and supporting(e.g.,carbon sequestration and biodiversity).We also summarized four main approaches to shrub management:burning,biological,chemical,and physical removal.The connections between the ecosystem services affected by shrub encroachment and the United Nations Sustainable Development Goals(SDGs)were highlighted to achieve synergies across multiple objectives.We emphasize the importance of quantification and monitoring in understanding the causes,consequences,and management of shrub encroachment.We advocate for long-term,location-based,and globally networked experiments and recommend the integration of new technologies,such as LiDAR,drones,and artificial intelligence,into shrub encroachment research.In conclusion,our study provides a comprehensive dataset and research framework for scholars studying shrub encroachment,aiming to deepen our understanding of this ecological process.

文摘While oceanic and coastal acidification has gained increased attention,long-term pH trends and their drivers in large freshwater systems remain poorly understood.The Laurentian Great Lakes are the world’s largest freshwater system,and in many ways resemble marine ecosystems.However,unlike the open ocean and coastal waters where pH has declined due to rising atmospheric CO_(2),no significant pH trends have been observed in the Laurentian Great Lakes,despite significant ecosystem changes driven partly by the invasion of dreissenid mussels.This study examined 41 years of field observations from Lake Michigan to investigate the long-term carbonate chemistry dynamics.Observational results revealed substantial declines in both total alkalinity(TA)and dissolved inorganic carbon(DIC)over the four decades.Mussel shell calcification emerged as the primary mechanism behind these declines,accounting for 97%and 47%of the observed changes in TA and DIC,respectively,lowering water column pH by 0.24 units.Elevated carbon accumulation in soft mussel tissues,coupled with long-term changes in the air-water pCO_(2)gradient during summer,significantly contributed to long-term DIC variations,explaining 18%and 28%of the lake-wide DIC loss.These two mechanisms also resulted in an overall pH increase of 0.09 and 0.12 units,largely offsetting the calcification-driven pH decrease.These findings bridge a gap in acidification research for large freshwater systems and provide valuable insights for comprehensive lake-wide management strategies.

文摘Biological invasion is a pressing environmental and ecological challenge worldwide.Cabomba caroliniana(C.caroliniana),a submerged macrophyte native to South America,is listed as a high-priority invasive species in several countries.It is critical to understand how water temperature influences its invasiveness for effective management.However,research on the effects of water temperature on C.caroliniana the growth is limited.This study used controlled experiments to examine how water temperature(5-30℃)affects the morphological,physiological,photosynthetic,and stoichiometric traits of C.caroliniana.The results showed that broad water temperature tolerance of C.caroliniana significantly impacts its reproductive capacity and invasive potential.At 5-10℃,cold stress induced carotenoid synthesis and total organic carbon accumulation,enabling adaptation to low temperatures.However,C.caroliniana grew slowly,as its root development was limited,and its invasiveness remained low.At 20-30℃,increased chlorophyll synthesis and enhanced resource-use efficiency supported rapid growth,including more branches,leading to high invasion and dispersal potential.Thus,C.caroliniana exhibited strong colonization and spread quickly in tropical and subtropical waters(>20℃).In temperate zones,populations can be established during summer(20-25℃)and survive winter hrough cold adaptation.We recommended prioritizing control measures during warm seasons(20-30℃)to disrupt propagule dispersal,alongside early monitoring in temperate waters to inhibit ecological invasion.

文摘The seasonality of Haemaphysalis longicornis in the United States comprises overlapping life stages in the spring and summer.This is partially attributed to the ability of all stages to survive the winter.Physiological condition in ticks refers to nutritional reserve levels and is often used to characterize tick populations.To determine if lipids were suitable for estimating the physiological condition in H.longicornis,lipid content was measured in unfed laboratory-reared ticks for up to 480 d.The results showed that lipids decrease significantly over time in adults(36%at 183 d),nymphs(33%at 63 d)and larvae(28%at 102 d)and could be used to study the population structure of field-collected H.longicornis.Lipids extracted from field-collected ticks(March to October)were measured to determine if different groups or cohorts could be identified during the season.The spring nymph population included high-and low-lipid groups that partially overlapped in April and May.In larvae,the lipid content of ticks in the spring was significantly higher than in the fall,suggesting that active larvae in the early fall do not overwinter.The analysis of lipids in adults showed that high-and low-lipid adults were present throughout the season,suggesting a continuous influx of recently molted adults until the end of the adult season,where only low-lipid ticks are found.The analysis of physiological condition in the Asian longhorned tick demonstrated a complex univoltine structure with some overlap in adults from different years.

文摘Prevention of biological invasion requires understanding how alien species invade native communities.Although studies have identified mechanisms that underlie plant invasion in some habitats,limited attention has focused on invasion patterns along elevational gradients.In this study,we asked which factors drive the global and regional distribution of the invasive plant Galinsoga quadriradiata along elevational gradients.To answer this question,we examined whether human activities(i.e.,roads)promote G.quadriradiata invasion,how seed dispersal-related traits of G.quadriradiata change along elevation gradients,and whether G.quadriradiata has adapted to high-elevation environments through phenotypic plasticity or genetic variation.On the global scale,we found that human activities and road density positively contribute to the G.quadriradiata expansion in mountainous areas.Field surveys in China revealed significant elevational differences in the seed dispersal traits of G.quadriradiata,with higher-elevation populations exhibiting lower dispersal ability and generally lower genetic diversity.Under common conditions,high-elevation populations showed higher leaf mass ratio but lower root mass ratio and reproductive allocation.This suggests that high-elevation environments create a barrier to dispersal for G.quadriradiata,and that G.quadriradiata has adapted phenotypically to these conditions.Our study indicates that the elevational invasion pattern of G.quadriradiata is shaped by multiple factors,particularly human activities and phenotypic adaptability.In addition,our finding that G.quadriradiata invasion at high elevations is not constrained by low genetic diversity indicates that monitoring and management of G.quadriradiata in mountainous areas should be strengthened.

文摘Non-native plants are increasingly recognized as ecosystem engineers across a wide range of ecosystems.While their impacts on understory composition have been widely documented,consequences for community assembly remain largely unexplored.We investigated the engineering impacts of Sorbaria sorbifolia,a naturalized Rosaceae shrub,on abiotic conditions and understory community assembly in Central European forests.Across 60 plots spanning coniferous and deciduous stands,we quantified light availability,organic layer C/N ratio and thickness,and understory functional diversity along an invasion gradient.Using ordination and linear regression,we found that increasing S.sorbifolia cover reduced light availability,thickened the organic layer,and altered C/N ratio in contrasting,forest-type-specific ways.In coniferous stands,invasion increased C/N and strongly suppressed understory light,whereas in deciduous stands it reduced C/N with weaker shading effects.These changes translate into consistent declines in functional richness and dispersion,particularly in coniferous forests where invasion led to homogenization of the understory.Trait shifts indicated stronger habitat filtering under invasion,with declines in specific leaf area(SLA)and increases in leaf dry matter content and seed mass,reflecting exclusion of light-demanding species and persistence of stress-tolerant taxa and woody seedlings.Remarkably,once S.sorbifolia exceeded~50%cover,positive relationships between habitat properties and understory functional diversity collapsed,replaced by uniform light limitation.This threshold effect highlights S.sorbifolia as an ecosystem engineer,capable of transforming forest structure and regeneration trajectories.Early detection and management are therefore crucial to prevent long-term homogenization and the formation of novel,invasion-driven forest states.
文摘AIM:To investigate the efficacy and safety of 90°inferonasal sectoral goniotomy with an micro-vitreoretinal(MVR)blade in patients with mild-to-moderate primary open-angle glaucoma(POAG)and pseudoexfoliation glaucoma(PEXG).METHODS:This retrospective study included data from 60 patients(60 eyes)who underwent stand-alone goniotomy or goniotomy with phacoemulsification between August 2021 and January 2023,and 45 eyes underwent goniotomy combined with phacoemulsification,and 15 eyes underwent goniotomy as a stand-alone procedure.Postoperatively,intraocular pressure(IOP)and the number of medications were collected at 1,3,6,and 12 mo.The side effects of surgery were recorded 1 d,1 wk,and 1,3,6,and 12 mo postoperatively.The primary outcomes were a reduction in IOP of at least 20%from baseline and a decrease in the number of antiglaucomatous medications in 1 a postoperatively.The secondary outcome was surgical success,defined as an IOP<18 mmHg with(qualified)or without(complete)antiglaucomatous medication at 1 a postoperatively.RESULTS:At the end of 1 a,78%of patients achieved both a>20%reduction in IOP and a reduction in the number of medications used.Overall success was achieved in 63%of patients.Microhyphaema was the most common complication,none of the patients experienced a complication requiring surgical intervention.CONCLUSION:Sectoral inferonasal goniotomy with an MVR blade significantly reduced IOP and the number of medications required in patients with POAG and PEXG,and 1-year follow-up after goniotomy showed that the need for filtering surgery was either eliminated or delayed in a significant number of patients.

文摘BACKGROUND Robotic assistance is increasingly used for donor and recipient hepatectomy in liver transplantation,yet existing evidence is fragmented and variably indirect.AIM To evaluate clinical outcomes,surgical performance,and economic effects of robotic-assisted donor and recipient hepatectomy in the transplant pathway.METHODS Following Preferred Reporting Items for Systematic reviews and Meta-Analyses 2020 and a priori registration,systematic reviews were included with or without meta-analysis.Four databases were searched through July 2025.Methodological quality was appraised with a measurement tool to assess systematic reviews(AMSTAR 2),and certainty was graded with grading of recommendations assessment,development and evaluation(GRADE).Evidence overlap was calculated via a citation-matrix-based corrected covered area(CCA).Effect sizes were prespecified as risk ratios(RR)for dichotomous outcomes and mean differences for continuous outcomes.RESULTS Five reviews met the inclusion criteria,four with meta-analyses and one consensus review used only for context.Donor(direct)findings were more favorable for robotics in terms of estimated blood loss(≈-117 mL)and length of stay(≈-0.6 days),although with longer operative time(≈+105 minutes).Absolute risks for donor complications were not estimable from ratio-only data.Recipient(indirect)meta-analysis indicated robotics to be favorable in terms of conversion(RR≈0.41)and severe morbidity(RR≈0.81),with a trend toward lower overall morbidity(RR≈0.92)and no difference in 30-day mortality.Differences in length of stay and operative time were small and heterogeneous.Economic evidence(indirect,network meta-analysis)suggested higher procedural costs for robotic vs laparoscopic intervention,but lower hospitalization costs vs open intervention,with laparoscopy the least expensive overall.AMSTAR 2 ratings were moderate-to-high across the reviews,GRADE certainty was low for key donor continuous outcomes,and low-to-moderate for recipient and economic outcomes.Overlap was slight(graded-corpus CCA=0.0%;including a contextual non-transplant review increased CCA to≈1.25%).CONCLUSION Robotic donor hepatectomy confers perioperative advantages at the cost of longer operative time.Recipient and economic findings are indirect and considered hypothesis-generating.Transplant-specific,prospective comparisons using a minimum standardized dataset and uniform outcome definitions are needed to resolve remaining uncertainties and to clarify the cost-utility correlation.
