Great Lakes Nonindigenous Occurrences: Thalassiosira pseudonana was recorded for the first time in the Lake Erie drainage in an Ohio artesian well in 1973, but it may have been present at an earlier date elsewhere in the Great Lakes drainage. Thalassiosira also promotes high rates of growth and fast rates of repair, as it has a high protein and amino acid content. Bulk measurements are impacted by senescent cells and detritrus.

Diatom blooms are frequently terminated by aggregation and subsequent sedimentation (Alldredge and Gotschalk, 1989; Jackson, 1990).The formation of large, fast sinking aggregates was proposed to be an integral part of the life cycle of many diatom species (Smetacek, 1985) but also contributes significantly to carbon flux thus being important for the global carbon cycle … gastropod: Reproduction and life cycles Food consists of diatoms (an algae group) and other small plankton collected by ciliary currents of the velum and channeled by the currents into the mouth.

PDF | On Jan 1, 2002, David G. Mann published Diatom life cycles | Find, read and cite all the research you need on ResearchGate Salinity below 20 or above 38 would likely damage or kill the cells (Schone 1974).

The relative content of separate lipid classes and their FA composition varied during of the life cycle. synchronized growth of thalassiosira pseudonana (bacillariophyceae) provides novel insights into cell‐wall synthesis processes in relation to the cell cycle 1 Mark Hildebrand Marine Biology Research Division, Scripps Institution of Oceanography, University of California, San Diego, 9500 Gilman Dr., La Jolla, California 92093‐0202, USA During the periods of active cell division and resting cell production, the proportion of polar lipids, as the structural components of cell membranes, increased. Using flow cytometry, I found that the centric diatom, Thalassiosira weissflogii, could be induced to undergo spermatogenesis by exposing cells maintained in continuous light to either dim light or darkness. An analysis of the expression and activity of silicon transporters (SITs) was done on synchronously growing cultures of the diatom Thalassiosira pseudonana to provide insight into the role these proteins play in cellular silicon metabolism during the cell cycle.

A PCR-based cDNA subtraction technique was used to identify genes that are expressed as small cells of the centric diatom Thalassiosira weissflogii …

The life of diatoms in the world's oceans. The Chrysophyta are algae which form endoplasmic cysts, store oils rather than starch, possess a bipartite cell wall and secrete silica at some stage of their life cycle.
