Bauxite mining has caused serious damage on local ecosystems and landscapes in the Eastern Amazon, Brazil. Considering these issues, the objectives of this study were to determine key species and their ecological characteristics that can contribute to forest restoration after bauxite mining. Key species are those with high frequency and abundance in different stages of vegetation succession. Data were

Grassland has sustained serious desertification due to inappropriate human activity in arid and semi-arid areas. This desertification has disrupted ecosystem structure and function. However, desertification on the grassland's C:N:P stoichiometry (Carbon, Nitrogen, and Phosphorus) are poorly understood, which undermines management and restoration of desertified grassland. To improve our knowledge, we

River embankments offer potential semi-natural habitats for grassland species, but their large-scale reconstruction leads to vast vegetation loss. To restore both ecosystem services and biodiversity on reconstructed river embankments, we tried to achieve rapid cover by native grasses and to enhance the richness of species typical of semi-natural grasslands. We conducted a 4-year experiment to clarify

The European flat oyster, Ostrea edulis, is an important ecosystem engineer that has been progressively disappearing from European coasts over the last century mainly due to overexploitation, habitat degradation and disease. It is now the subject of many conservation and restoration programs throughout Europe, including the Flat Oyster REcoVERy (FOREVER) project in France. Protecting and managing the

Submerged vegetation is essential for maintaining a clear water state in shallow lakes. To determine the optimal submerged macrophyte coverage required to improve water quality, field investigations and a simulation experiment were carried out in a sub-lake of Baiyangdian Lake, China. The effects of two seasons and five submerged macrophyte coverage gradients (0 [C-0], 25 [C-25], 50 [C-50], 75 [C-75]

Constructed wetlands are a nature-based engineering solution enabling polishing of septic tank effluents at low-cost. However to date, the influence of planting on treatment efficiency remains little understood. Here we report a case study evaluating the performance of two near-identical Horizontal Sub-Surface Flow Constructed Wetlands (HSSF-CW) deployed at a school in southern India. The HSSF-CWs

Despite several studies, role of eco-restoration strategies involving trees and grasses on soil organic carbon pools and fractions, response of soil enzymes in degraded land of tropical climate has remain largely overlooked. Four native fast growing fodder trees, namely, Ficus infectoria, Morus alba, Acacia nilotica and Leucaena leucocephala with combination of grasses viz., Cenchrus ciliaris, Chrysopogon

Although the treatment of eutrophied lakes with aluminium (Al) compounds has been established for more than 40 years, publications reporting on long-term consequences for phytoplankton are rare. Here we present observations from Lake Barleber for the period 1985–2016. The lake was treated in autumn 1986 because of high phosphorus (P) concentrations and cyanobacteria blooms, which limited the lake's

Regeneration by sprouting in secondary forests is a necessary technique not only for the utilization of forest resources, but also for maintaining forest health by regrowth and avoiding slope instability caused by over-sized aboveground biomass. The strength of soil reinforcement by roots generally decreases during the tree death process in deforestation, such as clear-cutting, whereas root system

Fishways are used worldwide to restore fish migration routes. However, there are few standardized metrics that allow the comparison of their performance in a consistence manner. This paper aims to assess fishway internal passage using two standardized metrics: passage success and transit time. Data from selected 20 field stepped fishways evaluation were gathered from a systematic review and own field

Vadose zone is an important channel for sulfonamide contamination into groundwater, and the processes of adsorption and migration in the vadose zone are complicated. In this study, we focused on three sulfonamide antibiotics (sulfamethoxazole, sulfamethazine and sulfamethoxypyridazine) in the groundwater of Limin drinking water resource in northeastern China and assessed their migration potential in

Technosols are defined by the World Reference Base as soils subjected to a strong human influence and containing at least 20% of artefacts. The construction of Technosol using recycled waste material is considered an appealing sustainable use of both natural and anthropic resources. Constructed Technosol can attract and host a multitude of soil organisms, forming a reserve of biodiversity. In this

Three distinct septic systems designed for onsite removal of nitrogen (N) from residential wastewater were installed at the Massachusetts Alternative Septic System Test Center (MASSTC) and at homes across Suffolk County (SC), New York. All configurations featured nitrifying sand beds coupled with denitrifying biofilters composed of 1) a lined, saturated sand and woodchip layer, 2) a saturated box filled

Atlantic salmon (Salmo salar) smolt migration through standing waters is generally known to be associated with slow migration speed and low success. Most previous studies have however been conducted on impounded waters. The bathymetry and specifically the flow dynamics around the outlets differ markedly between impounded lakes and naturally draining lakes. To date no study has attempted to disentangle

Understanding environmental factors controlling vegetation and soil attributes is crucial for the prediction of future climate change impacts on ecosystem functioning. This study conducted at 10 sites in South Mediterranean grasslands along aridity gradient aims to determine the possible controlling factors (mean annual precipitation MAP, mean annual temperature MAT and soil pH) that may affect vegetation

The beneficial effects of plant roots in decreasing soil detachment in forest ecosystems exposed to rill erosion are well known. However, these effects vary largely between different plant species. There has been lots of research into the relationship between root-soil systems and rill erodibility with a particular focus on grass species. Conversely, fewer studies are available for tree species, especially

A 2.7-km canalised section of the Kallang River, a major storm-water drain and reservoir spillway in Singapore, was rehabilitated into a 3-km naturalised, meandering river between 2009 and 2011. A combination of plants, natural materials, and civil engineering techniques were introduced to soften the edges of the waterway, to give it a more natural appearance and prevent soil erosion. Baseline data

There is a causal relationship between atmospheric concentrations and ecosystem fluxes of DCM, CF, and CT. Atmospheric concentrations of these gases likely regulate ecosystem fluxes, and they may also be influenced in turn by exchanges with the ecosystem. The relationship between atmospheric concentrations and fluxes of DCM, CF, and CT is bound to affect the occurrence and fate of these gases in the

The Bonnet Carré Spillway (BCS) was constructed from 1929 to 1936 to protect the city of New Orleans from the Mississippi River floods. When the water stage of the Mississippi River is over 5.18 m of flood stage, BCS will be opened to divert the excessive flood water into the Gulf of Mexico through Lake Pontchartrain. During these flood release events, large amounts of freshwater, sediment and nutrients

In the Eastern Amazon, abandoned and unproductive areas are widespread and normally found as a result of soil degradation. In this study we presented the following scientific question: Is it possible to improve the quality of soil physical and biological attributes of areas previously occupied by abandoned pastures with commercial plantation of the native species Dipteryx odorata? To respond this question

Old hydroelectric power stations often provide unsafe migration routes to fish, apart from passing through mobile gates during high flow. The installation of retrofitted bypass is considered to be a potential solution to improve fish passage at such old structures, but their performances are often insufficient. In the Amblève River (Belgium), a mobile 3.3 m high dam feeds two principal Francis turbines

Wetlands are one of the most important ecosystems for the biodiversity of plants and animals. Especially, Gangcheon wetland in NamHan river, Korea is a very valuable one because Aster altaicus var. uchiyamae, which is one of endemic plants is inhabited. However, Gangcheon wetland was impaired by a river improvement project called ‘Four Major Rivers Project’. After the project, Gangcheon wetland restoration

Wetlands play an important role in the global carbon cycle but are intensively disturbed by humans. Estimating the gaseous carbon budget of degraded wetlands has great significance for wetland conservation. The Shanyutan wetland is a degraded tidal wetland in Southeast China. We compared the landscape patterns of Shanyutan in 2009 and 2019 based on remote sensing images and determined the sediment

Constructed treatment wetlands are a common practice for filtering nitrogen from agricultural sub-surface (i.e. tile) drainage in the Midwest. Wetland size recommendations typically depend on watershed size, but little is known about the effectiveness of wetlands with a pooled area as small as 0.11 ha combined with a high infiltration rate and sub-surface treatment. A small, edge-of-field wetland treating

Brownfield surface is expanding in Europe, but as often abandoned or underused, these areas become refuge for microbial, faunal and floral biodiversity. However, brownfield sites are generally contaminated, likely posing severe environmental risks. At a former wood preservation site contaminated with Cu, we evaluated the efficiency of compost and dolomitic limestone incorporation into the soil, followed

In the current context of biodiversity erosion, ecological restoration is sometimes the only way to reinforce plant population and preserve them from the deterioration of their natural habitat. Dwarf bulrush (Typha minima Hoppe) is an endangered pioneer clonal plant, which grows in frequently disturbed habitats along Eurasian temperate piedmont rivers. In the Alps, its population has decreased by 85%

Artificial marine infrastructures now cover large stretches of the available natural shoreline in many parts of the world. This is having a substantial impact on the local marine ecosystems as biodiverse natural hard substrata are being replaced with man-made structures, which have been shown to support lower levels of biodiversity. The ecological value of artificial coastal structures could be enhanced

The installation of weirs leads to extensive alterations in species composition of riverbank vegetation, as they distinctly change the natural disturbance regime of rivers. Due to their infrastructural significance, the removal of most weirs and impoundments is unlikely, which is why restoration measures along impounded rivers are strongly limited. To evaluate the restoration potential of weir-near

Evaluation of the impact of transport on the surrounding environment requires an ecosystem approach: to analyze components that provide information about the distribution of concentrations of the monitored contaminants and to allow an estimate of the dynamics of movement of these substances in the environment. Trees are used for biomonitoring for wide range of contaminants, coming not only from air

Mineralisation process of Greenhouse gas (GHG) emission data from a sludge treatment wetlands (STWs) has been lacked currently. A study was conducted to quantify the release rates of carbon dioxide (CO2) and methane (CH4) from three similar pilot-scale STW units in relation to seasonal change based on the release rates in order to estimate annual GHG release rates of mineralisation process. A static

Land use management plays a key role in mitigating urban river pollution. Past research has addressed how primary land uses influence river water and sediment quality, but has given limited attention to the subdivision of primary land uses to a secondary level, limiting the accurate identification of potential sources of pollutants. The current study, using Bayesian Networks, investigated how the hierarchical

The present study aimed to investigate biochemical responses of filamentous algae integrated with surface waters in Yavuzeli-Araban catchment (the south-east of Turkey) by the use of a multivariate approach. This catchment having anthropogenic activities and different climate could affect environmental variables of surface waters, changed the biochemical compounds of filamentous species. A canonical

The urban food garden is an interesting natural solution to the need to develop sponge cities structured and designed to absorb and capture rain water for reducing flooding, worldwide. This study applied a storm water management model and field experiments to investigate properties of the garden substrates. Taipei City was taken as a case study as the Taiwan government has promoted urban food garden

The effects of the seasonal groundwater level fluctuations on the redox species in groundwater and the microbial communities in aquifer media were investigated at a typical riverbank filtration (RBF) site in northeast China. A total of 50 groundwater samples were collected to illustrate the variations of oxidation-reduction potential (ORP), dissolved oxygen (DO) and redox species such as iron (Fe2+)

We posit that a better meshing of traditional engineering disciplines and ecological restoration science is central to achieving environmental repair at the scale and pace required to combat globally ever-growing, human caused, land degradation and biodiversity loss. Ecological restoration is an increasingly vibrant endeavour supported by diverse fields of research. But there is a rapidly emerging

Soil moisture and physical characteristics strongly influence plant-available water and surface crust strength, which affect seedling emergence. We test interactions between rainfall amount and topsoil and waste rock blends and their impact on restoration outcomes in a semi-arid environment. Seedling emergence was evaluated in eight species across three winter rainfall treatments (low (ambient) 68 mm

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
