Picoplankton BIOMASS in the Ross Sea (Antarctica)
Polar Biology, 1993Spatial distribution of picoplankton in the Ross Sea was studied. The authors discuss the biomasses of various picoplanktonic-sized fractions and of bacterial cells between 0.2 and 2.0 μm capable of growing on Marine Agar 2216 (Difco). Picoplankton having a cellular diameter cf between 1.0 and 2.0 μm (PP1) generally predominate, accounting for 73% of ...

Cyanobacterial Picoplankton from Lake Constance*
Botanica Acta, 1992AbstractFour types of unicellular cyanobacteria were classified by pigment composition and cell size. These originated from the picoplankton fraction of Lake Constance, Germany. β‐Carotene and zeaxanthin were found to be the main carotenoids of three Synechococcus isolates.

Picoplankton consists of those organisms found in the open waters of seas and lakes which are capable of passing through a filter with 2 μm pores but not through one with 0.2 μm pores. Cells in this size range are well adapted to planktonic life in that they sink extremely slowly and are more efficient than larger forms in taking up ...

Picoplankton in Lake Maggiore, Italy
Internationale Revue der gesamten Hydrobiologie und Hydrographie, 1995AbstractIn 1992 we examined the morphological characteristics and space‐time distribution of picoplankton cells in Lake Maggiore, a subalpine lake in which oligotrophication is in progress. We measured by image analyser the biovolume of autotrophic (APP), eukaryotic and prokaryotic. and heterotrophic (HPP) picoplankton.

Origin and Importance of Picoplanktonic DMSP
1996The importance of picoplanktonic particulate DMSP (DMSPp GF/F-2 µm) was investigated using size fractionation during a time-series experiment in the Mediterranean Sea and in three areas of the subtropical Atlantic Ocean. Picoplanktonic DMSPp accounted for up to 25% of depth-integrated total DMSPp (GF/F-200 µm) in oligotrophic waters.

Photosynthesis of picoplankton in the oligotrophic ocean
Nature, 1983Against a background of controversy concerning the absolute magnitude of biological productivity in the oligotrophic, tropical ocean1–4, evidence is accumulating for the existence there of a population of minute, unicellular organisms collectively known as picoplankton5,6.

The Oceanic Cyanobacterial Picoplankton
1994The initial interest in the phycoerythrin-containing picoplanktonic cyanobacteria, assigned to the genus Synechococcus, stemmed directly from a recognition of their considerable contribution to marine primary productivity, as well as to their widespread distribution in an environment hitherto characterized by its relative paucity of cyanobacteria ...

Winter picoplankton diversity in an oligotrophic marginal sea
Marine Genomics, 2018Marine picoplankton, unicellular organisms with cell sizes up to 3 μm in diameter, numerically dominate marine ecosystems, encompassing Archaea, Bacteria, Eukarya (protists and fungi) as well as viruses. Autotrophic and heterotrophic picoplankton abundance and community composition with a focus on picoeukaryotes (PEs) were investigated in the winter of

Importance of Picoplankton in Lake Superior
Canadian Journal of Fisheries and Aquatic Sciences, 1986In Lake Superior, approximately 50% of total primary production is attributable to phytoplankton that pass through a 3-μm screen. The <3-μm size class is dominated by eukaryotic flagellates, nonmotile eukaryotic cells (1 μm), and chroococcoid cyanobacteria.
