Abstract. A new version of the Integrated Nitrogen in Catchments model (INCA) was developed and tested using flow streamwater nitrate concentration data collected from River Kennet during 1998. INCA is a process-based nitrogen cycle plant/soil in-stream systems. The simulates export different land-use types within river system, ammonium concentrations at daily time-step. structure differs original, that soil-water retention volumes have been added interface adapted to permit multiple crop...
Abstract. Implementation of the Nitrates Directive (NiD) and its environmental impacts were compared for member states in northwest European Union (Ireland, United Kingdom, Denmark, Netherlands, Belgium, Northern France Germany). The main sources data national reports third reporting period NiD (2004–2007) results MITERRA-EUROPE model. considered is fairly comparable regarding restrictions where when to apply fertilizer manure, but very different application limits N fertilization. Issues...
Abstract Increasing dissolved organic carbon (DOC) concentrations have been reported during the last 15 years in streams from United Kingdom, Northern Europe and North America. Identifying sources of DOC controls delivery to stream is important understand significance these trends. This relies on availability observations dynamics storm events, since much export soils occurs high flows. study analyses data for eight events winter 2005–2006 a small agricultural experimental catchment—the...
Abstract A new integrated hydrological and nitrogen model, called TNT2 (topography‐based transfer transformation), has been developed to study fluxes in small catchments. This process‐based spatially distributed order take spatial interactions into account, kept as simple possible. Here, only the module is discussed. The two main hypotheses of model are taken from TOPMODEL concept (constant hydraulic gradient equal slope conductivity decreasing exponentially with depth). based on a daily...
Abstract In this work, we first tested the influence of low‐molecular‐weight (LMW) fucoidan extracted from pheophicae cell wall on bidimensional cultured normal human osteoblasts' behaviors. Second, by impregnation procedure with LMW bone biomaterial (Lubboc®), explored in extracellular matrix context its capabilities to support osteoblastic behavior 3D culture. bidimensionnal cultures, evidenced that promotes osteoblast proliferation and collagen type I expression favors precocious alkaline...
Abstract Acquired carbapenemases currently pose one of the most worrying public health threats related to antimicrobial resistance. A NDM ‐1‐producing Salmonella Corvallis was reported in 2013 a wild raptor. Further research needed understand role birds transmission bacteria resistant carbapenems. Our aim investigate presence carbapenem‐resistant Escherichia coli gulls from southern France. In 2012, we collected 158 cloacal swabs samples two gull species: yellow‐legged ( Larus michahellis)...
Core Ideas AgrHyS is a long‐term observatory of the agroecosystem. supports strongly interdisciplinary environmental research. offers an original experimental setup to explore soil–groundwater–water–plants–atmosphere continuum. and innovative techniques for monitoring. The agro‐hydrological dedicated studying processes controlling hydro‐chemical fluxes in headwater catchments response effects agricultural. composed instrumented located western France temperate oceanic climate that are...
Abstract Elevated nitrogen (N) concentrations have detrimental effects on aquatic ecosystems worldwide, calling for effective management practices. However, catchment-scale annual mass-balance estimates often exhibit N deficits and time lags between the trajectory of net inputs that riverine export. Here, we analyzed 40-year series surplus nitrate-N loads in 16 mesoscale catchments (104–10 135 km 2 ) a temperate agricultural region, with aim to (1) investigate fate ‘missing N’, either still...
