Full-text available
Direct and indirect effects from human activity have dramatically increased nutrient loading to aquatic inland and estuarine ecosystems. Despite an abundance of studies investigating the impact of agricultural activity on water quality, our understanding of what determines the capacity of a watershed to remove or retain nutrients remains limited. T...

The salt marshes of the Mont St. Michel bay represent a complex system in continuous change, mostly due to the frequent exchanges with the coastal waters through tidal processes. In such ecosystems, water is an important element insofar as it represents the common vector of flows between and among several ecosystem compartments. The purpose of the...
