Revolution in the ocean

Article Abstract:

Victor Hensen, a professor of medical physiology at Kiel University, Germany, was responsible for disseminating the view that the ocean's animals are fed by phytoplankton. He school he created at Kiel proved the significance of plankton and established an agricultural model as the basis for modern biological and chemical oceanography. His belief in the uniform distribution of plankton was disproved by his colleagues, but he defended this and his methods right up to his final paper.

Polar ocean ecosystems in a changing world

Article Abstract:

The possible effects of a warming world on polar ecosystems are examined and only the seas and oceans directly influenced by sea ice and it's melting are considered. The polar regions are changing, in some places rapidly and where these changes are a result of resource exploitation, the rate of change can be modified through management action.

A watery arms race

Article Abstract:

Scientists are becoming increasingly aware of the range of defence systems in plankton. Captured plankton cells have evolved specific defence mechanisms, including poisonous chemicals and strong organic cell walls.
