- Abstract:
- ... The Everglades ecosystem in Florida, USA, is naturally phosphorus (P) limited, and faces threats of ecosystem change and associated losses to habitat, biodiversity, and ecosystem function if subjected to high inflows of P and other nutrients. In addition to changes in historic hydropattern, upstream agriculture (sugar cane, vegetable, citrus) and urbanization has placed the Everglades at risk due ...

Fertilizer use in agricultural lands and treated wastewater disposal have increased bioavailable nitrogen (N) and phosphorus (P) loading to wetlands and aquatic systems with potential implications for nutrient cycling and soil microbial processes. Recently, conflicting results of N loading impacts on microbial-mediated organic matter decomposition in coastal wetland soils have been reported. Howev ...

DFAS can handle traditional objective non-determinacy (caused by natural element) and anthropogenic uncertainty (caused by artificial factor) expressed as probability distribution and fuzzy set in objective function or constraint; it also ...

Asymmetric root distribution pattern on steep terrain is analysed by combining GPR (Ground Penetrating Radar) image analysis with a theoretical root distribution model and is verified with field investigation data. Root distribution and morphology of a mature deciduous tree were analysed in terms of the plant’s anchorage needs in an asymmetric loading condition scenario. The GPR method was combine ...

- Abstract:
- ... Constructed treatment wetlands have been well established as effective and sustainable solutions to the problem of urban water treatment and reuse. However, treatment wetlands located in aridland cities may behave differently relative to their more mesic and humid counterparts, and this could potentially impact their ability to deliver the ecosystem services that are expected of them. Specifically ...

Constructed treatment wetlands are particularly attractive treatment options in arid urban environments where water reuse is important for dealing with scarce water resources. Emergent macrophytes play an important role in nutrient removal, particularly nitro ...

Although gully restoration is frequently employed to recover degraded soils and reduce sediment yield to rivers and reservoirs, analysis of the evolution of this type of action after a long period of time is not so commonplace.

P concentrations in the rivers around the Bohai Sea have been amplified by fertilizer and sewage inputs associated with the development of industry and agriculture. Yet, knowledge of the characteristics of P is lacking at the main rivers which were inflow i ...
