Diatoms
A diatom (New Latin, Neo-Latin ''diatoma''), "a cutting through, a severance", from el, διάτομος, diátomos, "cut in half, divided equally" from el, διατέμνω, diatémno, "to cut in twain". is any member of a large group comprising several Genus, genera of algae, specifically microalgae, found in the oceans, waterways and soils of the world. Living diatoms make up a significant portion of the Earth's Biomass (ecology), biomass: they generate about 20 to 50 percent of the oxygen produced on the planet each year, take in over 6.7 billion metric tons of silicon each year from the waters in which they live, and constitute nearly half of the organic material found in the oceans. The Protist shell, shells of dead diatoms can reach as much as a half-mile (800 m) deep on the ocean floor, and the entire Amazon basin is fertilized annually by 27 million tons of diatom shell dust transported by transatlantic winds from the African Sahara, much of it from the Bodélé Dep ...

Species Description
A species description is a formal description of a newly discovered species, usually in the form of a scientific paper. Its purpose is to give a clear description of a new species of organism and explain how it differs from species that have been described previously or are related. In order for species to be validly described, they need to follow guidelines established over time. Zoological naming requires adherence to the ICZN code, plants, the ICN, viruses ICTV, and so on. The species description often contains photographs or other illustrations of type material along with a note on where they are deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million species have been identified and described, out of some 8.7 million that may actually exist. Millions more have become extinct throughout the existence of life on Earth. Naming process A name of a new species becomes valid (available in zo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gottlob Ludwig Rabenhorst
Gottlob Ludwig Rabenhorst (22 March 1806 – 24 April 24) was a German botanist and mycologist. Biography Rabenhorst was born in Treuenbrietzen. He studied in Berlin and Belzig from 1822 to 1830, worked as a pharmacist in Luckau until 1840, and received his doctorate in Jena in 1841. From 1840, he lived in Dresden, relocating to nearby Meissen in 1875, where he died aged 75. Renowned for his research of cryptogamic flora native to central Europe, his name is associated with ''Dr. L. Rabenhorst's Kryptogamen-Flora von Deutschland, Oesterreich und der Schweiz''. Rabenhorst edited the scientific journal '' Hedwigia'' from 1852 to 1878. With Alexander Braun (1805–1877) and Ernst Stizenberger (1827–1895), he was editor of the exsiccata Exsiccata (Latin, ''gen.'' -ae, ''plur.'' -ae) is a work with "published, uniform, numbered set of preserved specimens distributed with printed labels". Typically, exsiccatae refer to numbered collections of dried herbarium specimens respectivel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
