Medlin and co-workers erected a new class, Mediophyceae (which could be re-ranked a subclass if diatoms as a whole are ranked as a class rather than a phylum) for the "polar centric" diatoms, which they consider to be more closely related to the pennate rather than to other centric diatoms, a concept which has been followed or further adapted ...
An example of proxies is the use of diatom isotope records of δ13C ... The blend of diatom species found in a corpse may be the same or different from the ...
Diatoms are eukaryotic organisms in the phylum Bacillariophyta. This page contains articles about diatoms and diatomists.. Older classifications used to subdivide diatoms into Centrales and Pennales (with Bacillariophyceae used as a class), whereas more recent ones use a three classes system: Bacillariophyceae, Coscinodiscophyceae and Fragilariophyceae.
Italicized entries are articles about species in monotypic genera; these are redirected to their appropriate genus article. Pages in category "Diatom species" The following 51 pages are in this category, out of 51 total.
Thalassiosira pseudonana is a species of marine centric diatoms.It was chosen as the first eukaryotic marine phytoplankton for whole genome sequencing. [1] T. pseudonana was selected for this study because it is a model for diatom physiology studies, belongs to a genus widely distributed throughout the world's oceans, and has a relatively small genome at 34 mega base pairs.
Some species are bloom forming diatoms in eutrophic lakes. The type species is Fragilaria pectinalis Lyngbye from designating a lectotype from Conferva pectinalis O.F.Müller. [2] The taxonomy of the genus is still uncertain. [3] Fragilaria has been the dominant genus of diatoms in Lake Mývatn in Iceland for at least 1200 years. The genus ...
The species of diatom is dependent upon the age and paleoecology of the deposit. In turn, the shape of a diatom is determined by its species. Many deposits throughout British Columbia, such as Red Lake Earth, are from the Miocene epoch and contain a species of diatom known as Melosira granulata. These diatoms have a small globular shape.
Bacteriastrum is a genus of diatoms in family Chaetocerotaceae. [1] There are more than 30 described species in genus Bacteriastrum, but many of these are not currently accepted, and new species are still added to the genus. [2] The type species for the genus is Bacteriastrum furcatum Shadbolt.
