Physicochemical and biological cycles in a tide dominated, nitrogen-polluted temperate estuary

Spatio-temporal variations in the physicochemical and biological parameters in the Morlaix estuary on the Brittany coast of France were studied. Hydrographically, the estuary can be classified into 3 segments: the upper estuary where stratification always persists, the lower estuary where vertical homogeneity is permanent, and a middle estuary where there is a regular oscillation of stratification and homogeneity during every tidal cycle, stratification being associated with slack waters and homogeneity, with ebb and flood. Nitrogen pollution in the estuary is very intense.

Coping with excess salt in their growth environments: osmoregulation and other survival strategies deployed by the mangroves

Mangroves are defined as a collection of woody plants and the associated fauna and flora that use a coastal depositional environment. Here the specific effects of salinity changes in mangroves have been examinated.
