To evaluate the relative importance of photosynthetic versus morphological adaptations submersed macrophytes to low light intensity in lakes, rapid curves (RLCs), parameters, growth rate (RGR), clonal reproduction and abundance two (Potamogeton maackianus Vallisneria natans) were examined under 2.8%, 7.1%, 17.1% 39.5% ambient a field outdoor experimental study. The plants increased their initial slope RLCs (α) decreased minimum saturating irradiance (Ek) maximum electron transport (ETRm)...
Summary Trait‐based approaches provide a framework for integrating the distribution of functional traits associated with ecological strategies into responses plant community dynamics along environmental gradients. We used trait‐based approach to unravel processes governing macrophyte assembly water depth gradient. sampled 42 plots and 1513 individual plants measured 12 abundance 17 species. The results showed significant evidences habitat filtering (i.e. reduction in range variance trait...
Light is a major limiting resource in aquatic ecosystems and numerous studies have investigated the response of submerged macrophytes to low light conditions. However, few tested whether different strategies can also consequences for macrophyte distribution along littoral slopes lakes, which are known affect biomass due differences drag forces sediment characteristic. In this study, we (1) two species growth forms (canopy-forming: Potamogeton maackianus, rosette-type: Vallisneria natans)...
Ubiquitous nitrate (NO3−) in groundwater sources is considered a hazard compound for human health. Photo-catalytic reduction by Ag-TiO2/formic acid/visible light represents an emerging method NO3− removal without secondary pollution. In this contribution, the of photo-catalytic and selectivity N2 were systematically investigated under varied conditions, including concentrations Ag-TiO2, NO3−, formic acid (HCOOH). The efficiency reached 84.47%, 82.68% which was converted to optimal...
High-frequency nitrate-N () data are increasingly available, while accurate assessments of the importance in-stream retention processes is deviating stream orders still unclear. In this presentation we hypothesize that similar diurnal nitrate uptake pattern exists in different and these patterns can reveal insights into dominance across scales. To test assumption continuous 15-min estimates  retention was derived a 1st  a 6th-order reach lower Bode River network (27.4 km,...
Abstract In‐stream nitrate (NO 3 − ) uptake in rivers involves complex autotrophic and heterotrophic pathways, which often vary spatiotemporally due to biotic abiotic drivers. High‐frequency monitoring of NO mass balance between upstream downstream measurement sites can quantitatively disentangle multi‐path dynamics at the reach scale. However, this approach remains limited a few river types has not been fully explored for higher‐order streams with varying hydro‐morphological biogeochemical...
Abstract Evaluation and improvement of cultivated land system resilience (CLSR) play a significant role in the sustainable development land. From perspective multifunction land, this study revealed spatiotemporal evolution CLSR China's major grain‐producing regions during 2000–2020 by catastrophe model based on comprehensive evaluation including production (PR), ecological (ER), economic (CR), further identified key drivers to find scientific paths improve CLSR. The results demonstrated that...
依据文献报道的洱海水质、水文(水位)和沉水植被(物种组成、生物量及分布面积)数据,分析了近50年来洱海的水质变化、水位波动情况以及沉水植被的演替过程,探讨了驱动洱海沉水植被演替的主要环境因子.分析表明,洱海沉水植被群落经历了原生、过渡、顶级和衰退等主要阶段;自1980s以来,流域入湖营养盐增加、水质持续下降、藻类生物量逐年升高、沉水植被群落结构简单化和抑藻功能退化等因素是驱动洱海沉水植被演替与分布的原动力,水位大幅波动加速了洱海水生态系统由清水态向浊水态转变,并导致沉水植物大量衰退和某些特有物种消失.因此,在洱海水生态系统的治理以及沉水植被的恢复过程中,应优先考虑降低外源营养盐输入和优化水位调控.;Based on the past 50 years data,we made a time-series analysis of relationships among water quality,hydrology (e.g.,water level fluctuation) and submerged macrophyte succession (e.g.,species...
Abstract Understanding the role of ecosystem services (ES) and their interactions at different spatial scales in territorial space governance is crucial for sustainable development. However, a unified analysis scale zoning effects on ES supporting development remains theoretical practical gap. Therefore, this study utilized traditional concept modifiable areal unit problem (MAUP) to establish ES‐MAUP framework. Additionally, highly urbanized region Southern Jiangsu, China, was selected as...
The effect of biodiversity on ecosystem productivity has been a controversial issue in ecological research. species richness–productivity relationship is highly variable natural ecosystems, with positive being one the most commonly observed relationships. Previous regional studies from terrestrial ecosystems have demonstrated that environmental gradients can regulate relationship. However, how this varies freshwater across spatial environment remains unclear. In study, we propose be...

In this study, the relationship amongst phytoplankton species composition abiotic environmental factors on seasonal changes community free-living attached bacteria Lake Erhai were studied. Using Illumina high-throughput sequencing, we found that impact both bacterial was greater than community, which total phosphorus, Secchi disk, water temperature, dissolved oxygen...
近几十年来,在入湖营养盐增加,水质持续下降,藻类生物量逐年升高及水位大幅波动下,洱海沉水植物群落演替速度加剧.2016年7月调查显示:洱海沉水植被退化严重,物种数量显著低于近期(2011年)历史水平,分布面积较有记录的历史最高水平(1980s)下降超过70%,优势物种由1960s的海菜花(Ottelia acuminata)、蓖齿眼子菜(Stuckenia pectinata)和大茨藻(Najas marina)等转变为微齿眼子菜(Potamogeton maackianus)、金鱼藻(Ceratophyllum demersum)以及苦草(Vallisneria natans).沉水植物群落在浅水区(0~2.5 m)主要遭受了浮叶植物细果野菱(Trapa maximowiezii)过度生长带来的生境胁迫,在中等水深区(2.5~4 m)面临微齿眼子菜和金鱼藻的过度生长导致的群落结构的单一化影响,而在深水区(>4...
