TL;DR: Water loss from simulated green roof systems (microcosms) each containing 1 of 14 plant species belonging to 4 growth forms (succulents, herbaceous dicots, grasses and woody creeping shrubs) was quantified for three watering treatments (watering to field capacity every 4, 11 and 24 days).

TL;DR: In this paper, Wu et al. presented an experimental study on the effect of soil moisture content on the shear strength of root-reinforced soils by conducting in situ shear tests.

TL;DR: Of the three constructed wetlands, the VFRB was the most reliable performer under low and high strength influent conditions, indicating aerobic unsaturated wetland to be the most suitable form of the technology for pathogen removal.

TL;DR: This study examined the uptake of some metals by T. latifolia and the transfer from roots to other plant parts and demonstrated that T. Latifolia L. could be considered as either a bio-indicator or aBio-accumulator for sediments and water polluted by metals.

TL;DR: In this paper, the variation of total soil carbon with depth in two temperate (Ohio) and three tropical (humid and dry) wetlands in Costa Rica and compares their total soil C pool to determine C accumulation in wetland soils.

TL;DR: In this paper, two experimental water transfers from the Yangtze River to Lake Taihu were conducted in winter-spring 2002 and in summer-autumn 2003, and the results showed that the experimental water transfer in both of the periods have notable positive effects on debasing the concentration of phytoplankton, total nitrogen and dissolved oxygen in some sub-areas.

TL;DR: In this article, the authors investigated vegetation development on unfertilised thin extensive vegetated roofs during a 3-year period and found that S. album and S. acre were the dominant species on the roofs.

TL;DR: In this article, a full-scale experimental study was conducted on a hybrid constructed wetlands plant designed for 100 person equivalents, which was composed of a first stage of vertical filters (fed with raw wastewater), followed by a second stage of horizontal filters.

TL;DR: In this article, the level of DTPA extractable metals in casts and tissues of earthworms (endogeic: Metaphire posthuma (Vaillant) and anecic: Lampito mauritii Kinberg) and ingesting soils, collected form cultivated land, urban garden and sewage soils.

TL;DR: In this paper, the feasibility of using sub-surface horizontal flow constructed wetlands to treat municipal wastewater in Hong Kong was investigated and two different hydraulic retention times and different types of treatments (with and without vegetation) were investigated.

TL;DR: It is concluded that the compact SCBR was practical to treat municipal wastewater and the shift of microbial community monitored by molecular technologies could offer guidance to the process optimization in engineering.

TL;DR: In this article, the epigeic earthworm Eudrilus eugeniae Kinberg was used for vermicomposting of post-harvest residues of some local crops, e.g., wheat (Triticum aestivum), millets (Penniseum typhoides and Sorghum vulgare), and a pulse (Vigna radiata) under laboratory conditions.

TL;DR: In this paper, the influence of dams on the hydrologic regime of the Huaihe River basin has been investigated using Indicators of Hydrologic Alteration and Range ofVariability Approach methods.

TL;DR: In this article, the trajectories of ecological succession and identify the main driving forces that control vegetation dynamic in reclaimed artificial slopes were analyzed. But the results obtained in the Teruel coalfield (Mediterranean dry Spain) during the last 30 years have quite limited.

TL;DR: In this paper, the influence of roads on landscape within Lancang River Valley was analyzed using GIS buffer, spatial comparison, and scenario analysis to elucidate the impact of road development on landscape.

TL;DR: Intermittent subsurface flow mangrove microcosms were constructed to investigate their capabilities in treating primary settled municipal wastewater collected from a local sewage treatment work in Hong Kong SAR and the effect of hydraulic retention time (HRT) as mentioned in this paper.

TL;DR: In this paper, the authors present the results of different case studies on the treatment of municipal wastewater with high-rate anaerobic systems, and focus on the capacity of these systems for removing suspended solids, and therefore on their potential as an appropriate pretreatment to avoid clogging in constructed wetlands and to improve efficiency.

TL;DR: In general, very low protozoan and helminth egg counts were found, and the system demonstrated efficient reduction of the wastewater indicator pathogens.

TL;DR: Based on the research results, it was suggested that the use of indigenous A. chroococcum strains might be suitable when producing and using bio-fertilizer.

TL;DR: In this article, the authors used root-shoot analysis of selected dominant plants across the roadside habitats revealed that plants of a particular microhabitat had similar above and below ground spread and biomass allocation patterns.

TL;DR: In this paper, a pilot associated with a swine facility (piggery) with 66 swine was developed to treat diluted manure, produce earthworms and vermicompost, and reduce air pollution.

TL;DR: In this paper, the potential of Leucaena leucocephala as an erosion control plant was investigated in terms of its capacity of root reinforcement, root profile and root shear strength.

TL;DR: In this article, a water treatment bed of a constructed wetland (CW) with subsurface horizontal flow used for municipal wastewater treatment was measured in two depths (0.2 and 0.5m) of the treatment bed at regular distances from inflow using platinum electrodes, continuously, every 15min during a more than 2-year period (27 months) from 2002 to 2004.

TL;DR: Generally constructed wetlands were more efficient than algae-based systems when considering both, efficiencies in % and surface removal rates, and overall differences were not statistically significant.

TL;DR: In this article, the optimization for rock phosphate solubilization by phosphate-solubilizing fungi (Candida krissii, Penicillium expansum and Mucor ramosissimus ) isolated from phosphate mines (Hubei, PR China) was investigated.

TL;DR: In this paper, the applicability of an integrated constructed wetland system for P removal from low-strength wastewaters was investigated, where both units were packed with oyster shells (OS) as adsorption and filtration media.

TL;DR: In this article, the biosorption capacities and adsorption rates of Cr(VI) and Cu(II) ions onto live and dried tea fungal biomass were evaluated.

TL;DR: Wang et al. as discussed by the authors used Kosteletzkya virginica as an agroecoengineering species for alternative agricultural production and for revegetation of salt-affected tidal flats in China's east coast.

TL;DR: In this paper, the flux rate of CH4 in constructed wetlands (CWs) was evaluated to test the influence of plant species, and the highest CH4 flux rate was obtained in the Zizania latifolia systems and higher emission was found with higher influent load.

TL;DR: In this paper, the authors adopted the emergy analysis method to evaluate the sustainability of Macao's exchange processes in 2004 with respect to the life-support systems outside the city, tourism, and waste treatment processes.
