In constructed wetlands (CW), denitrification usually accounts for >60% of nitrogen removal and is supposedly affected by the inflow water and the wetland management practices. Fluctuations in nutrient concentration of inflow water can cause an impact in sediment properties and microbial communities living therein. We have estimated the effects of a high input of nitrate or nitrite (simulating an eutrophication

Mangrove-mud coasts across the world erode because of uninformed management, conversion of mangrove forests into aquaculture ponds, development of infrastructure and urbanization, and/or extraction of groundwater inducing land subsidence. The accompanied loss of ecosystem values, amongst which safety against flooding, has far reaching consequences for coastal communities, exacerbated by sea-level rise

Artisanal gold mining in Amazon forests and rivers has been reported in all Amazonian countries. Amazon mining has a wide range of negative effects and severe environmental and social consequences. Given that the activity in the region is mostly illegal, there are few studies published in the scientific literature on recovery of areas degraded by gold mining. This study conducts an experimental reforestation

Antibiotics are widely found in aquatic environments and pose a serious threat to natural habitats. Plants as an important part of constructed wetlands, phytoremediation is a potential way to purify antibiotic contaminated waters and soils and thus reduce the risk of antibiotic resistance. However, less is known about Response mechanism of typical wetland plants and removal of water pollutants under

Due to increasing global changes, understanding the corresponding change in provisioning ecosystem services is becoming increasingly important. Climate and land use change have been identified as two major environmental change variables and will affect ecosystem services extensively. Nevertheless, the impact of these two factors on ecosystem services, especially their relative importance and combined

The European eel (Anguilla anguilla (L.)) is critically endangered after a multi-decadal decline. Anthropogenic disruption to downstream migration, including at water control structures such as pumping stations, is thought to be one of the contributing factors. Some pumping stations only operate during floods and river water drains through sluice gates under the influence of gravity (‘gravity sluice’

Vegetated buffers and filter strips are a widely used Best Management Practice (BMP) for enhancing streamside ecosystem quality and water quality improvement through nonpoint source pollutant removal. Most existing studies are either site-specific, rely on limited data points, or evaluate buffer width and slope as the only design variables for predicting sediment reduction, not considering other parameters

Disentangling the contributions of environmental gradients and spatial distance as species distribution drivers is a crucial topic of community ecology. Here, we sampled wetland plant communities at 779 plots from 52 sites and measured 12 key functional traits of 52 plant species in Poyang Lake, China. Using the generalized dissimilarity model (GDM), we examined which environmental variables and geographic

Invasive alien species can exhibit different degrees of invasion and colonize multiple districts due to their strong adaptability [e.g., the notorious invasive alien species Conyza canadensis (L.) Cronq. (originated from North America)]. We verified that the degree of C. canadensis invasion (based on its relative abundance in colonized communities) was critical to the functional similarity and dissimilarity

The objective of the research presented here was to determine the effectiveness of applying electrolysis in polluted sediment to enhance ammonia nitrogen (NH3−N) and phosphate phosphorous (PO43−-P) removal from sediment and overlying water. A magnesium‑aluminum (MgAl) alloy was used as the anode, and a titanium (Ti) mesh served as the cathode with a low-current of 40 mA (5 V) in polluted river sediment

To characterize the plankton size structure and evaluate plankton community stability in Longhu Lake, a shallow eutrophic lake in southeast China that has been biomanipulated for ~20 years, the biomass-size spectra of the plankton were seasonally studied from August 2017 to November 2018. The plankton-size spectra revealed a typical bimodal structure in all seasons. The higher peak consisted of small-sized

Mixed-species vegetation, such as that in semi-natural meadows, is increasingly adopted in urban green infrastructure to enhance habitat quality and aesthetic value; however, little is known regarding the consequences of using meadow mixes in river revetments. In the present study, 20 herbaceous species that naturally occur in habitats with infrequent and periodic inundation were mix-planted in hydrology-induced

The Hangang River and Imjingang River estuaries in Korea are part of the main transit route for many migratory birds that use the East Asia-Pacific flyway. Despite the global importance of this area as a seasonal bird stopover site and resting area, conservation areas have not been established in this area based on ecological properties. This study aimed to examine the umbrella effect of the white-naped

Excess nutrient inflow from tile-drained agricultural fields significantly contributes to the pollution of surface waters in Lithuania. Therefore, two parallel experiments, each using three pilot-scale woodchip-denitrifying bioreactors, were conducted for 2.5- and 1.5-year periods to test whether activated carbon (C) and flaxseed cake (both 10% v/v) and biochar (10% v/v and 20% v/v made of deciduous

Cancer, as well as the phenomena of cancer villagers, has attracted great concern from national and internal publics because of the high morality for population. Reference to long latency periods and multiple causalities for several cancers, cancer villages have usually used as circumstantial evidence for an association with cancers and environmental determinants relevant to economic-agricultural and

Stormwater biofilters rely on healthy plant communities to perform essential functions of stormwater management. Mycorrhizae are a class of fungi which may confer benefits to plants growing in green stormwater infrastructure, just as they do in natural ecosystems. Few studies have investigated the roles of mycorrhizae outside natural ecosystems or agricultural systems. This review describes three mechanisms

Ecological restoration programmes have been initiated worldwide because of serious environmental degradation. However, the effectiveness of ecological restoration remains contentious because vegetation restoration is impacted by both climate change and human activities. Climate change is an important factor for vegetation restoration, especially in ecologically vulnerable areas. The Zhangjiakou region

Soil salinization threatens agricultural sustainability, especially for arid and semiarid regions. Planting euhalophytes with drip irrigation is proposed to be a feasible solution for the reclamation of saline soils. Thus, by planting an annual halophyte Suaeda salsa with drip irrigation, we assessed the potential of S. salsa to accumulate high amount of salt from soil and change in soil salinity levels

Drained peatlands dominated by purple moor grass (Molinia caerulea) are widespread in the UK and Western Europe. Although substantial carbon stores may be present in these peatlands, in this degraded state they are not currently acting as carbon sinks. Therefore, M.caerulea dominated peatlands have been identified as potential sites for ecohydrological restoration to tackle the current climate emergency

Fishway research has long focused on post-establishment assessments to optimize fish passage efficiency. Model-based optimization with the use of hydrodynamic-habitat models (HHMs) has rarely been employed to investigate passage suitability based on key hydraulic variables.

The study focused on the attractiveness of mulches (consisting of the addition of a layer material to the soil surface) and their efficiency to promote recolonization by pedofauna of isolated and degraded areas. The experimental study was set up in the former coal mining area of Northern France. This area is particularly disturbed and fragmented by land-use change, urbanization, industry, intensive

Constructed wetlands are used as an effective measure to improve water quality and reduce nutrient runoff from agriculture. However, their role as alternative breeding sites for different amphibian species is rarely explored. We studied amphibians' colonization and breeding success in two in-stream free surface water wetlands in intensively managed agricultural landscape in south-eastern Estonia. Additionally

Soil infiltration is an inevitable process of the mutual transformation of surface water and groundwater in the ecological hydrologic cycle that helps to transport nutrients required by plants to the root system, thus promoting vegetation growth and maintaining ecological stability. It is of utmost importance to simulate the process of soil infiltration and calculate the key parameters of soil water

Although understanding the requisite hydrodynamic habitat for mangrove vegetation is vital for successful restoration efforts, few studies have quantitatively assessed the in-situ tolerance of mangroves to relevant physical forcing mechanisms. In this work, hydrodynamic thresholds for the persistence of mangrove vegetation (Rhizophora mangle, Avicennia germinans, and Laguncularia racemosa) are assessed

Interest and investment in constructing living shorelines rather than harder engineering structures are on the rise worldwide. However, the performance of these interventions in rejuvenating coastal habitats, depositing fine sediments with elevated organic content, and reducing erosion varies widely and is often low along energetic shorelines. In this study, we test the efficacy of a living shoreline

Alkaline leachate from bauxite residue disposal areas is likely to require treatment for post-closure. Traditional treatment methods are not attractive in the long-term due to management requirement, energy input and operational logistics and passive approaches offer an alternative approach. Constructed wetlands are widely cited as a potential treatment option but there is limited data on long term

Tree species and afforestation age can affect soil carbon (C) and nitrogen (N) sequestration as well as soil properties through different litter input and microbial activities. However, uncertainty remains because the responses vary under different climates and prior land uses. A site-specific study was conducted to investigate the dissimilarities in plant litter, soil properties, and soil microbial

Soil microorganisms are important for maintaining multiple functions of terrestrial ecosystems. Understanding the spatial and temporal distribution of soil microbial communities and their key determinants is one of the central goals of microbial ecology. In this study, we used an artificial ecosystem called the Ecorium, which a system with a series of biomes including tropical forest, desert, Mediterranean

The universalization and decentralization of wastewater treatment is one of the greatest challenges faced in Brazil. In this context, Constructed Wetlands (CWs) may be considered environment friendly and economically viable alternative for geographically remote locations, having fewer financial resources and infrastructure. During the last years, studies have investigated different configurations aiming

The construction of bioretention facilities in collapsible loess areas faces some problems such as low infiltration rate of rainwater runoff and system blockage, which seriously affect the treatment effect of bioretention cell on rainwater runoff. According to the different filler matrix, three bioretention cells with improved filler were constructed, the 1# bioretention system was filled with 50%

The impact of the development of cascade reservoirs on the biogenic substance cycle is an important scientific issue for the future sustainable development of the Lancang-Mekong River. The vertical distribution of phosphorus (P) fractions of Xiaowan (XW) and Nuozhadu (NZD) Reservoir sediment in Lancang River were studied to better understand the environment influence of cascade deep reservoir for the

While evapotranspiration (ET) is an important component of the global water cycle, its temporal variations (ΔET) and underlying mechanisms are controversial. Based on the newest FLUXNET dataset and six ET products, we investigate ΔET for different ecosystem types during the recent two decades (1995–2014). We found an ET hiatus (decreasing in ET) at most sites (46 of 67) based on both in-situ observations

Urban-industrial restoration of complex native vegetation, such as grassland-forest mosaics could counteract land degradation and help develop methodology for larger scale complex restorations. We have studied the impact of grassland reconstruction techniques, the resulting biotic conditions, plus abiotic conditions on early woody survival in a forest-steppe reconstruction at an urban-industrial site

Land cover changes following rewetting of 73 thousand hectares of peatland after the severe 2010 peat fires in Moscow Region (Russia) were monitored using multispectral remote sensing. The results revealed a reduction in the area of bare peat and dry grasslands, the rapid expansion of willow and birch vegetation, and a steady increase in wet grasslands and open water. Both the number and area of peat

Effective grassland restoration practices can promote degraded meadows recovery. However, little has been documented regarding the effect of water addition on the restoration of degraded meadows in the Qinghai–Tibetan Plateau (QTP). A field experiment with five water addition levels was established to identify the interactions between soil bio-physicochemical properties and plant of the degraded alpine

Railway networks are linear landscape elements that are mostly accompanied by adjacent lineside vegetation. In order to maintain safe railway operation, lineside vegetation must be continuously monitored and maintained. A large-scale assessment approach to identify safety-relevant woody vegetation structures along a railway corridor is presented in this paper. Based on accurate surface and terrain

To date, urban plant selection has mainly been focused on species-level characteristics such as aesthetics and suitability to form assemblages. In natural environments, however, plant species form natural assemblages based on positive (and negative) ecological interactions. Implementing an assemblage-level approach to plant selection in an urban context that utilises ecological interactions between

Transplantation of soil and plant litter has been suggested as a tool to speed up the establishment of target communities during restoration. In this study, we explored the effect of transplanting soil and plant litter on plant and soil biota communities in an already afforested limestone quarry. Soil or plant litter from a mature deciduous forest was transplanted into post-mining sites overgrown by

The passing efficiency of the fishway for water plant dam in Liuxi River was evaluated by statistical analysis and comparison with other fishway based on the monitoring data from August in 2015 to July in 2016. The main contents of this paper includes that identifying the fish species, analyzing the influence factors of season and upper water level on passing efficiency, and comparing the result with

Runoff is an important factor in maintaining the normal operation of wetland ecosystems. An effective runoff simulation can provide an important decision basis for wetland protection and ecological restoration. Aiming to make the spatial resolution of remotely sensed precipitation products match the existing high-precision digital elevation model (DEM), this study used multiple linear regression (MLR)

Runoff decrease triggered or exacerbated by human activities over the past decades on the Loess Plateau has been drawing nationwide concerns; quantifying human-induced runoff-altering factors is of great significance for decision-making on maintaining regional water, ecological and economic security. Sediment-trapping dams (STDs) construction and revegetation are the two major soil-water conservation

This study analyzed the capability of two species to take up metals from gold mine tailing storage facility seepage in a constructed wetland with horizontal subsurface flow. Naturally populated Typha domingensis (cattail) and introduced Chrysopogon zizanioides (vetiver) were sampled on a regular basis in two experimentation cycles; a monoculture of T. domingensis in the first cycle and a mixed culture

As coral restoration efforts increase globally, there is a growing need to not only increase post-restoration monitoring, but also advance reef restoration monitoring methods. Utilizing autonomous technology to compliment manual, SCUBA-based monitoring will diversify the types of data available to coral restoration practitioners and aid in determining the efficacy of restoration efforts. This study

A conventionally-designed bioretention cell, consisting of very sandy media meant to achieve high infiltration rates, was studied for its hydrologic and treatment performance over two monitoring periods: 2013–2014 (immediately post-construction) and 2017–2018 (4–5 years post-construction). Given the limited literature on mature performance of bioretention, the purpose of this study was to determine

Highly disturbed landscapes, including fallowed or abandoned farmland, are known to experience losses in native plant diversity that negatively impact the ecological functions and services provided by an ecosystem. The restoration of native species to the post-agricultural landscape using principles derived from indigenous knowledge could reverse this damage. This study examines the effects of three

Anaerobic oxidation of methane (AOM) plays an important role in regulating methane (CH4) emissions from coastal wetland ecosystems. In recent decades, coastal estuarine wetlands have been subjected to great environmental pressure associated with terrestrial nitrogen (N) input. Here, we used 13CH4 to quantify AOM rates in coastal wetland sediments with and without vegetation in the Yangtze River Estuary

Eutrophication is the prime water quality issue in inland waters. Eutrophication and its key symptom, harmful cyanobacterial blooms, is expected to further increase in the future, which highlights the importance of managing the issue. The reduction of external nutrient load is crucial but might not bring fast relief to eutrophic waters due to ongoing diffuse pollution and legacy nutrients in the sediment

Hydropeaking is an anthropogenic regime that results from the strong flow variations in the receiving waters of storage hydropower plants. These variations are due to flexible energy production, i.e. the sudden increase of electricity demands or from its decrease, affecting the fish assemblages of that river stretch. We evaluated the mitigation potential of the hydropeaking diversion hydropower plant

Pavements, rooftops and compacted soils inhibit rainfall infiltration across our cities and drains built to prevent flooding can further reduce water availability to urban ecosystems. These hydrological changes diminish the provision of ecosystem service benefits to local populations and negatively impact downstream communities and environments. Stormwater engineering can help restore infiltration

The Great Dismal Swamp (GDS) is a 45,000-ha state and federally protected Coastal Plain peatland located on the border of North Carolina and Virginia that contains stands of Bald cypress and the globally threatened Atlantic white cedar. Centuries of drainage and logging have substantially altered the hydrology of the GDS, negatively affecting its ecosystem structure and function. To restore a seasonally
