    Biomass and production in polar planktonic and sea ice microbial communities: a comparative study

    Algal and bacterial biomass and production were measured in the plankton, platelet ice and congelation ice communities at one station in McMurdo Sound, Antarctica during September and October 1986. Bacterial a...

    Effects of altered photic regimes on diel patterns of species-specific photosynthesis

    Diel patterns of photosynthesis were measured for two polar diatoms (Coscinodiscus sp. and Porosira pseudodenticulata) collected in September 1985 from McMurdo Sound, Antarctica, and four temperate dinoflagellate...

    Carbon-14 labelling patterns of individual marine phytoplankton from natural populations

    Photosynthate incorporation into lipids, low molecular weight compounds, polysaccharides and proteins by individual phytoplankton species isolated from natural populations is described. This sensitive method u...

    Phosphorus metabolism of oceanic dinoflagellates: phosphate uptake, chemical composition and growth of Pyrocystis noctiluca

    The phosphorus metabolism of Pyrocystis noctiluca Murray (Schuett) 1886 has characteristics which may enhance its potential for success in orthophosphate impoverished waters. The steady-state phosphate uptake rat...

    Light-shade adaptation by the oceanic dinoflagellates Pyrocystis noctiluca and P. fusiformis

    Species-specific rates of photosynthetic carbon uptake (P), chlorophyll a content and P versus irradiance (P-I), have been measured for cells of Pyrocystis noctiluca and P. fusiformis isolated from natural popula...

    Phytoplankton patchiness and frontal regions

    In the Chesapeake Bay estuary there are persistent seasonal frontal and interfrontal regions that serve to deliver and retain different phytoplankton populations. The “patchiness” of phytoplankton, both in tot...

    Characterization of alkaline phosphatase and organic phosphorous utilization in the oceanic dinoflagellate Pyrocystis noctiluca

    Phosphate depleted Pyrocystis noctiluca (Murray) Schuett 1895 has at least one phosphomonoesterase (EC 3:1:3:1) which is triphasic between 0.1 and 222 μmol P. The enzyme has a broad temperature range with maximum...

    Effects of lead on growth of the marine diatom Skeletonema costatum

    The growth rate and maximum yield of Skeletonema costatum (Grev.) Cleve in batch culture were inhibited by dissolved lead at concentrations of 0.05 to 10.0 μg Pb l-1. Growth rate, maximum yield, and respiration c...
