Australia's coastal ecosystems alone save the rest of the world costs of around 23 billion US dollar a year by absorbing CO2 from the atmosphere. Coastal ecosystems such as seagrass meadows, salt mars...
For millions of years, symbiotic bacteria have lived inside the gills of Lucinidae clams found in seagrass meadows located along tropical coasts, such as the Florida Keys. These bacteria play a crucia...
Increasing water temperatures are responsible for the accumulation of a chemical called nitrite in marine environments throughout the world, a symptom of broader changes in normal ocean biochemical pa...
Factors in the decline of coastal ecosystems.
The influence of science in the recognition of the effects of landscape changes on coastal ecosystems and in the development of effective policy for managing and restoring these ecosystems is exami...
Nutrient over-enrichment has resulted in major changes in the coastal ecosystems of developed nations in Europe, North America, Asia, and Oceania, mostly taking place over the narrow period of 1960 t...
During recent human history, human activities such as overhunting and habitat destruction have severely impacted many large top predator populations around the world. Studies from a variety of ecosyst...
Until recently, it was believed that biological assimilation and gaseous nitrogen (N) loss through denitrification were the two major fates of nitrate entering or produced within most coastal ecosyste...
This region is defined here as Tuticorin Coast, India, and their outlying islands. Tuticorin Coast climate is strongly influenced by the surrounding sea water. Key climatic features include tropic...

We compared seasonal studies of ciliates and heterotrophic dinoflagellates conducted in Disko Bay (West Greenland, ~69°N) and the Kattegat (Denmark, ~56°N). In both systems, ciliates and heterotrophic...
Export of organic matter from the surface to deeper waters often shows much smaller seasonal variations than primary production or nitrate-based new production in mid- to high-latitude marine systems...
