Skeletonemataceae
Skeletonemataceae is a family of diatoms in the order Thalassiosirales. There is currently only one known genus in this family of diatoms known as ''Skeletonema'' as reported from diatom.org. Being from the Thalassiosirales order means that Skeletonemataceae are centric diatoms. The sexual reproduction of oogamous is where reproduction occurs by the union of mobile male and immobile female gametes. This way of reproduction is possible due to the lack of significant motility which is also a defining trait of ''Skeletonema''. References Thalassiosirales Diatom families {{Diatom-stub ...

Skeletonema
''Skeletonema'' is a genus of diatoms in the family Skeletonemataceae Skeletonemataceae is a family of diatoms in the order Thalassiosirales ''Thalassiosirales'' is an order of centric diatoms. The order currently contains 471 species. Species in the order Thalassiosirales are common in brackish, nearshore, and .... It is the type genus of its family. The genus ''Skeletonema'' was established by R. K. Greville in 1865 for a single species, ''S. barbadense'', found in the Barbados deposit ung 2009 These diatoms are photosynthetic organisms, meaning they obtain carbon dioxide from their surrounding environment and produce oxygen along with other byproducts. Reproduce sexually (sexual reproduction is oogamous) and asexually uiry 2011 ''Skeletonema'' belong to the morphological category referred to as centric diatoms. These are classified by having valves with radial symmetry and the cells lack significant motility orner 2002 ''Skeletonema'' are cylindrical shaped with a sil ...

Thalassiosirales
''Thalassiosirales'' is an order of centric diatoms. The order currently contains 471 species. Species in the order Thalassiosirales are common in brackish, nearshore, and open-ocean habitats, with approximately the same number of freshwater and marine species. The Thalassiosirales species ''Thalassiosira pseudonana'' was chosen as the first eukaryotic marine phytoplankton for whole genome sequencing Whole genome sequencing (WGS), also known as full genome sequencing, complete genome sequencing, or entire genome sequencing, is the process of determining the entirety, or nearly the entirety, of the DNA sequence of an organism's genome at a .... ''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. Scientists are researching on diatom light absorption, using the marine diatom ''Thalassiosira''. Refe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Skeletonema Costatum
''Skeletonema costatum'' is a cosmopolitan centric diatom that belongs to the genus '' Skeletonema''. It was first described by R. K. Greville, who originally named it ''Melosira costata,'' in 1866. It was later renamed by Cleve in 1873 and was more narrowly defined by Zingone et al. and Sarno et al. '' Skeletonema'' ''costatum'' is the most well known species of the genus ''Skeletonema'' and is often one of the dominant species responsible for red tide events. The diatom ''S. costatum'' is known for its carbon acquisition mechanisms, and it has been used in the production of biofuel and as a feed for aquaculture. The organism is appealing for commercial use due to its high photosynthetic efficiency, high tolerance to pH, temperature, and salinity changes, high lipid and fatty acid content, and rapid growth rate. Structure and morphology Cells belonging to ''S. costatum'' are single-celled but exist as long chains of about 6 to 24 cells but can be up to 60 cells in length. ...

Marie Lebour
Marie Victoire Lebour (20 August 1876 – 2 October 1971) was a British marine biologist known for her study of the life cycles of various marine animals. She published more than 175 works during her long career. Early life and education Marie Lebour was born the youngest of three daughters to Emily and George Lebour in Woodburn, Northumberland on 20 August 1876. Her father was a professor of geology and Marie regularly joined him on expeditions, collecting specimens for her own collections. She attended Armstrong College and studied art, then went on to Durham University, where she earned degrees in zoology: an associate degree in 1903, bachelor's degree in 1904, master's degree in 1907, and doctorate in 1917. Career and research In 1900, before beginning her scientific education, Lebour began her research career with a paper on land and freshwater molluscs in Northumberland. While studying for her master's degree, Lebour was on staff at Durham University. From 1906–1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
