Large-scale controls on potential respiration and denitrification in riverine floodplains
Restoration measures of deteriorated river ecosystems generally aim at increasing the spatial heterogeneity and connectivity of these systems in order to increase biodiversity and ecosystem stability. While this is believed to benefit overall ecological integrity, consequences of such restoration projects on biogeochemical processes per se (i.e. ecosystem functioning) in fluvial systems are rar...
متن کاملComparing denitrification rates and carbon sources in commercial scale upflow denitrification biological filters in aquaculture
Aerobic biological filtration systems employing nitrifying bacteria to remediate excess ammonia and nitrite concentrations are common components of recirculating aquaculture systems (RAS). However, significant water exchange may still be necessary to reduce nitrate concentrations to acceptable levels unless denitrification systems are included in the RAS design. This study evaluated the design ...
متن کاملErodibility and sedimentation potential of marly formations at the watershed scale
Grupi and Kashkan marl formations comprise a considerable part of Zagros region. These formations have a considerable erodibility and sedimentation potential because of their special geological and mineralogical characteristics. The objective of this study was to compare the erosion and sediment yield of Kashkan and Grupi formations in Merk watershed located in southeast Kermanshah, using the M...
متن کاملWater supply sustainability and adaptation strategies under anthropogenic and climatic changes of a meso-scale Mediterranean catchment.
Assessing water supply sustainability is crucial to meet stakeholders' needs, notably in the Mediterranean. This region has been identified as a climate change hot spot, and as a region where water demand is continuously increasing due to population growth and the expansion of irrigated areas. The Hérault River catchment (2500 km2, France) is a typical example and a negative trend in discharge ...
متن کاملEstimation of sediment denitrification rates at in situ nitrate concentrations.
The denitrification rates in a marine sediment, estimated by using N-nitrate, V(max), K(m), and sediment nitrate concentrations, were 12.5 and 2.0 nmol of N(2)-N cm day at 0 to 1 and 1 to 3 cm, respectively, at 12 degrees C. The total rate was 165 nmol of N(2)-N m day.
