Wetlands provide multiple ecosystem services such as storing and regulating water flows and water quality, providing unique habitats to flora and fauna, and regulating micro-climatic conditions. Conve...
Effect of salinity on seasonal community patterns of Mediterranean temporary wetland crustaceans: A mesocosm study
Effect of salinity on seasonal community patterns Mediterranean temporary wetland crustaceans A mesocosm study
2014/4/17
In a large-scale outdoor mesocosm experiment we studied the effects of salinity on successional patterns, diversity, and relative abundances of Camargue (southern France) temporary pool crustaceans. E...
Temporal and spatial variability in the cycling of nitrogen within a constructed wetland: A whole-system stable-isotope-addition experiment
Temporal spatial variability in the cycling of nitrogen a constructed wetland A whole-system stable-isotope-addition experiment
2014/4/17
Constructed wetlands attenuate effluent nutrients, are hydrodynamically well defined, and are a useful proxy for the study of nitrogen (N) transformation in eutrophic natural systems. A whole-system s...
