Fragilaria Improbula
''Fragilaria'' is a genus of freshwater and saltwater diatoms. It is usually a colonial diatom, forming filaments of cells mechanically joined by protrusions on the face and in the center of their valves. The individual diatoms appear swollen in their centers where they are joined to the colonial ribbon. The genus grows as both plankton and benthic species, free living in colonies or as epiphytes. 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. The taxonomy of the genus is still uncertain. ''Fragilaria'' has been the dominant genus of diatoms in Lake Mývatn A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface.

Hans Christian Lyngbye
Hans Christian Lyngbye (29 June 1782 – 18 May 1837) was a Danish priest and botanist, specialising in algae. Life Hans Christian Lyngbye was born in Aalborg, Denmark, in 1782, the son of a teacher, Jens Michelsen Lyngbye. He attended the Latin school in Aalborg until 1802 when he took as his tutor a priest on the island of Vendsyssel. He studied botany and theology and graduated in 1812. He then worked with the botanist Niels Hofman Bang which awoke his interest in algae. He won a competition set by the University of Copenhagen and as a result, Hornemann paid for the printing of his work on algae, ''Tentamen Hydrophytologiæ Danica'', which was published in 1819. It contained meticulous descriptions of 321 species of marine algae with illustrations of 70, including 7 new genera and 50 new species, and raised awareness of the algal flora of Denmark, Norway, the Faroe Islands and Greenland. He visited the Faroe Islands in 1817 and wrote a treatise on pilot whales and whaling. He w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
