Marine bio-diversity at different organizational levels (from genes to ecosystems). Overall differences in marine biodiversity in polar (examples from Arctic and Antarctica), temperate (mid-Norway) and tropical (Australia) ecosystems. How key-environmental variables (eg. light regime, temperature, salinity and nutrients) affect marine bio-diversity relation to climate induced processes. The importance of endosymbionts and kleptoplasty in species development. Relate bio-diversity at different levels to organisms at sea-surface, water column (nekton and plankton) and sea-floor (benthos). Biodiversity and age of ecosystems (time important development factor). Mass extinctions and explosions.
