Nutrient enrichment is an important stressor in coastal ecosystems. This analysis tests the
hypothesis that changes in nutrient loads, imbalances in nitrogen: phosphorus, and changes …

Several factors highlight the importance of dissolved organic matter (DOM) in coastal
ecosystems such as the Baltic Sea: 1) DOM is the main energy source for heterotrophic …

In both marine and freshwaters, the concentration of dissolved organic nitrogen (DON)
frequently exceeds that of dissolved inorganic nitrogen (DIN), including ammonium, nitrate …

Relative to inorganic nitrogen, concentrations of dissolved organic nitrogen (DON) are often
high, even in regions believed to be nitrogen-limited. The persistence of these high …

Florida Bay, a shallow, seagrass-dominated bay in southern Florida, USA, receives
significant nutrient inputs and has experienced seagrass losses and microalgal blooms …

Trends in nitrogen utilization, determined with 15 N-labeled substrates, were related to
blooms of distinct phytoplankton groups in the Gulf of Riga, Baltic Sea, during May, June and …

On a global scale tropical SE Asia is critical in terms of fluvial nutrient and sediment input
into the ocean as well as in terms of human modifications of the coastal zone altering these …

Dissolved organic carbon (DOC) load in discharges from cultivated soils may have negative
impacts on surface waters. The magnitude of the load may vary according to soil properties …

Ammonium is a central nutrient in aquatic systems. Yet, cell-specific ammonium assimilation
among diverse functional plankton is poorly documented in field communities. Combining …

Little is known about the relative importance of inorganic and organic nitrogen (N) sources in
fueling production of phytoplankton versus heterotrophic bacteria on the continental shelf …
