Phytoplankton Books


Algal Cultures and Phytoplankton Ecology


  • Phytoplankton 2nd Ed 1989 - Arthur Donald Boney Emeritus Professor of Botany University of Glasgow

    • PSU QK933.B66 1989
  • pelagic zone: water column of the open ocean
  • p001 thallus, no organization into tissues such as vascular structure

  • p001 all algae contain chlorophyll a, a poor absorber of green light

  • p003 Red tides toxic dinoflagellates

  • p013 coccolith plates of calcium carbonate, perhaps protective against predation

  • p016 Primary production autotroph produces own food heterotroph consumes producers

  • p017 Global primary production 1.4e14 to 1.8e14 kg/year dry matter, oceans only 35% of the total
    • why not 70%, proportional to ocean/land ratio? If land production remained the same, the total land plus ocean productivity could increase by a factor of 2.16 ... and that's before improving predation resistance and engineering new photosynthetic processes.

  • p018 PAR Photosynthetically active radiation

  • p018 Clear winter's day light intensity 20% of summer, 10% with clouds
  • p019 thylakoids membrane-bound compartments inside chloroplasts and cyanobacteria

  • p019 stroma

  • p019 pyrenoids

  • p019 phycobilin

  • p019 carotenes absorb UV, violet, and blue light

  • p019 xanthrophyll yellow pigments

  • p019 Sun vertical, 2% light reflection, near horizon 90% reflection
  • p021 humic acids

  • p021 gilvin colored humic substances

  • p023 depth d at which lowered white disk disappears
  • p023 surface inhibition, light too intense for phytoplankton
  • p024 continuous sunlight and prolonged calm injures Arctic phytoplankton and inhibits photosynthesis
  • p026 epilimnion surface layer hypolimnion depths metalimnion between

  • p026 sieche standing wave in body of water

  • p029 photosynthetic activity will increase pH in favor of bicarbonate users

  • p032 orthosilicic acid makes silica cell walls, 26% to 63%

  • p033 desmid green algae, progenitors of land plants

  • p034 Iron fertilization

  • p034 primary production may be limited by the availability of iron and other trace elements
  • p034 manganous = +2 oxidation state
  • p035 copper in plastocyanin mediates electron-transfer

  • p035 cyancobalamine B12 thiamine biotin B7 required by plantonic algae

  • p036 auxotrophs dependent on other sources of vitamins
