Distribution pattern of
picoplankton carbon biomass linked to mesoscale dynamics in the southern Gulf of Mexico during winter conditions.
Are
Picoplankton Responsible for Calcite Precipitation in Lakes?
In recent years, there has been an increase in research examining the contributions of
picoplankton and other small particles (<4 [micro]m) to bivalve growth.
Abundance and diversity of prymnesiophytes in the
picoplankton community from the equatorial Pacific Ocean inferred from 18S rDNA sequences.
The organisms also can be classified according to their size as
picoplankton (0.2-2 [micro]m), nanoplankton (2.1-20 [micro]m), microplankton (20.1-200 [micro]m), mesoplanktlon (201-2000 [micro]m) and macroplankton (> 2000 [micro]m) [1, 2].
In 1991, Schmidt and collaborators generated the first metagenomic library using DNA from marine
picoplankton [27], and, some years later, Healy et al.
east coast due to their eutrophication and higher temperatures: 1) the phytoplankton has shifted toward communities with abundant
picoplankton and nanoplankton, and 2) the species composition changed from an assemblage consisting mainly of immobile centric diatoms to one composed of flagellated species (Harding, 1994; Bricelj and Lonsdale, 1997; Kennish, 2001; Trice et al, 2004; Wasniak and Gilbert, 2004; Kemp et al, 2005; Mahoney et al.
Contribution of prokaryotic
picoplankton and eukaryotic nanoflagellates to total chlorophyll (% 23 to 47 and % 28 to 43, respectively) increased by about 50% from the coastal to the offshore station.

picoplankton, Nannochloropsis sp., with enriched carbon sources," Biotechnology Letters, vol.
Although most of the cyanobacteria literature describes marine
picoplankton as nontoxic, there are some reports of toxic effects caused by homogenized Synechococcus and Synechocystis and their extracts (Martins et al.
Metagenomic analysis of size-fractionated
picoplankton in a marine oxygen minimum zone.
In Lake Balaton picoeukaryotes dominated the winter
picoplankton, often constituting half of the total phytoplankton biomass (Voros et al., 2009).
