    Details
    ISSN: 1476-4687

    Notes: [Auszug] Viruses are the most common biological agents in the sea, typically numbering ten billion per litre. They probably infect all organisms, can undergo rapid decay and replenishment, and influence many biogeochemical and ecological processes, including nutrient cycling, system respiration, particle ...

    Notes: [Auszug] All living things need nitrogen. But its most common form, N2 gas, can be used only by microorganisms that possess the enzyme nitrogenase and can 'fix' nitrogen into a biologically usable form. Fixed nitrogen is a limiting nutrient in much of the ocean, meaning that there isn't enough of ...

    Notes: [Auszug] The bacterial group Prochlorococcus, discovered only a decade ago, may be the most abundant component of phytoplankton in the sea. These tiny (0.6 μm) organisms uniquely contain the photosynthetic pigments divinyl chlorophyll a and b, and are major primary producers in tropical and subtropical ...

    Notes: [Auszug] We observed a diverse array of virions (Fig. 1), many similar to known bacteriophages, with polygonal heads ranging in diameter from 30 to 160 nm; many had tails which were 50-200-nm long. Virion abundances ranged broadly from 106 to 1011 per litre of sea water (Table 1). Up to 7% of the ...

    Notes: [Auszug] The size of the nutrient field was calculated from the excretion rate per cell and the dispersion of nutrients away from the cell.We assumed that 40% of a phytoplankter's primary production is excreted; this represents a generous intermediate value from the wide range cited in the ...

    Notes: [Auszug] Our samples were collected from the western side of the California Current, roughly 350 miles west of San Diego. The area was oligotrophic at the time of sampling, as indicated by the low surface chlorophyll concentrations and a chlorophyll maximum layer at about 100 m depth, near the base of ...
