At Rancheros del Mar this phytoplankton fraction was mainly represented by tychoplankton diatoms, followed by planktonic diatoms, cyanobacteria, dinoflagellates, silicoflagellates and ebriids (Figs.
Approximately 300 species of dinoflagellates, diatoms, raphidophytes, prymnesiophytes, silicoflagellates, ciliates, and cyanobacteria are currently known to be, suspected to be, or have the potential to be harmful or toxic to a wide spectrum of organisms (Landsberg 2002, Berdalet et al.
Silicate forms an important parameter of phytoplankton distribution and its concentration in coastal water is influenced by proportional physical mixing of seawater with fresh water, adsorption of reactive silicate into suspended sedimentary particles, chemical interaction with clay minerals and biological removal by phytoplankton, especially by diatoms and silicoflagellates [28].
BSi, known as phytolith or opal, can be comprised of different components mainly of biological origin such as diatoms phytoliths, radiolarians, silicoflagellates and sponge spicules.
The small numbers of silicoflagellates and foraminifera were perhaps the result of undersampling of those single-cell organisms.
Diatoms are the most diverse (N = 171) and abundant taxa, followed by dinoflagellates (N = 84), silicoflagellates (N = 5), and cyanobacteria (N = 5; Garate Lizarraga 1992).
They also contained pelagic foraminiferans, phaeodarians, silicoflagellates, dinoflagellates, as well as some unidentified soft material.
Silica is also precipitated by radiolarians, silicoflagellates, horsetails and grasses.
