Guidelines for the scoping and environmental assessment of water resources projects. The environment and water resources projects - Volume 2 [PDF]

open access: yes, 1996
In its role as protector of the water environment, the Environment Agency requires significant water resources abstraction applications and schemes such as drought orders, drought permits, time limited licences, and river transfers to be environmentally

Restoring macrophyte diversity in shallow temperate lakes: biotic versus abiotic constraints

open access: yesHydrobiologia, 2013
Although many lake restoration projects have led to decreased nutrient loads and increased water transparency, the establishment or expansion of macrophytes does not immediately follow the improved abiotic conditions and it is often unclear whether ...

Functional Traits for Carbon Access in Macrophytes

open access: yesPLOS ONE, 2016
Understanding functional trait distributions among organisms can inform impacts on and responses to environmental change. In marine systems, only 1% of dissolved inorganic carbon in seawater exists as CO2. Thus the majority of marine macrophytes not only passively access CO2 for photosynthesis, but also actively transport CO2 and the more common ...

Agricultural pond restoration enhances species richness in non‐biting midges (Diptera: Chironomidae)

open access: yesRestoration Ecology, EarlyView.
Agricultural ponds are biodiversity hotspots, especially when restored to open‐canopy conditions. Studies comparing pre‐ and post‐restoration pond diversity are rare, however, and have widely focused on “easy‐to‐identify” taxa. Chironomids have so far been neglected in pond restoration studies, but are a highly speciose group critical to aquatic ...

Colonization by Chironomidae larvae in decomposition of Eichhornia azurea (Swartz) Kunth in an Amazonian lake in Brazil

open access: yesActa Scientiarum: Biological Sciences, 2015
Few studies have investigated the colonization of macroinvertebrates during macrophyte decomposition. The goal of this work was to study the colonization process of Chironomidae larvae during the decomposition of Eichhornia azurea in a lake in the ...

Seasonal dynamics of an aquatic macroinvertebrate assembly (Hydrobiological case study of Lake Balaton No. 2) [PDF]

open access: yes, 2007
In 2002, 2003 and 2004, we took macoinvertebrate samples on a total of 36 occasions at the Badacsony bay of Lake Balaton. Our sampling site was characterised by areas of open water (in 2003 and 2004 full of reed-grass) as well as by areas covered by ...

Extreme Variations of pCO2 and pH in a Macrophyte Meadow of the Baltic Sea in Summer: Evidence of the Effect of Photosynthesis and Local Upwelling

open access: yesPLoS ONE, 2013
The impact of ocean acidification on benthic habitats is a major preoccupation of the scientific community. However, the natural variability of pCO2 and pH in those habitats remains understudied, especially in temperate areas.

Functions of Macrophytes in Constructed Wetlands

open access: yesWater Science and Technology, 1994
Macrophytes have several intrinsic properties that makes them an indispensable component of constructed wetlands. The most important functions of the macrophytes in relation to the treatment of wastewater are the physical effects brought about by the presence of the plants.

Freshwater restoration effects on biodiversity and ecosystem services: a Delphi survey

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Freshwater ecosystem restoration is vital for halting biodiversity loss, enhancing resilience, and securing ecosystem services amid climate and land use change. With major initiatives like the United Nations Decade on Ecosystem Restoration and the European Union's Nature Restoration Regulation gaining momentum, identifying ...
