Seasonal fluxes of phosphate and ammonium across the sediment-water interface in a shallow small estuary (Palmones River, southern Spain)
Seasonal variations in oxygen, phosphate and ammonium fluxes between the sediment and overlying water were measured in a small shallow estuary (Palmones River Estuary, southern Spain) from July 1996Expand

Bioturbation by Nereis sp. and its effects on the phosphate flux across the sediment-water interface in the Palmones River estuary
The effects of Nereis sp. on the flux of dissolved phosphate across the sediment-water interface has been studied in Palmones River estuary using benthic flux-chambers and intact cores. DiffusiveExpand

Influence of bacterial density on the exchange of phosphate between sediment and overlying water
Fluxes of phosphate across the sediment–water interface have been measured using inhibitors of bacterial activity sterilization and chloramphenicol and a control in order to quantify the influence ofExpand

Alkaline phosphatase activity in marine macrophytes: histochemical localization in some widespread species in southern Spain
Alkaline phosphatase activity (APA) was determined in 44 species of marine macrophytes collected throughout 1991 and 1992 along the southern coast of Spain. Activity varied between 0.83 μmolExpand
