Didymium Squamulosum
Didymium ( el, , twin) is a mixture of the elements praseodymium and neodymium. It is used in safety glasses for glassblowing and blacksmithing, especially with a gas (propane)-powered forge, where it provides a filter that selectively blocks the yellowish light at 589 nm emitted by the hot sodium in the glass without having a detrimental effect on general vision, unlike dark welder's glasses. The usefulness of didymium glass for eye protection of this sort was discovered by Sir William Crookes. Didymium photographic filters are often used to enhance autumn scenery by making leaves appear more vibrant. It does this by removing part of the orange region of the color spectrum, acting as an optical band-stop filter. Unfiltered, this group of colors tends to make certain elements of a picture appear "muddy". These photographic filters are also used by nightscape photographers, as they absorb part of the light pollution caused by sodium street lights. Didymium was also used in ...

Heinrich Schrader (botanist)
Heinrich Adolf Schrader (1 January 1767 in Alfeld near Hildesheim – 22 October 1836 in Göttingen) was a German botanist and mycologist. He studied medicine early in life. He named the Australian plant genus ''Hakea'' in 1797. In 1795 he received his medical doctorate from the University of Göttingen, where in 1803 he became an associate professor to the medical faculty and director of the botanical garden. In 1809 he attained the title of "full professor" at Göttingen, where he taught classes until his retirement. Among his better known publications are ''Nova genera plantarum'' (1797) and ''Flora germanica'' (1806). The plant genus ''Schraderanthus'' is named in his honour. Schrader was elected a corresponding member of the Royal Swedish Academy of Sciences The Royal Swedish Academy of Sciences ( sv, Kungliga Vetenskapsakademien) is one of the Swedish Royal Academies, royal academies of Sweden. Founded on 2 June 1739, it is an independent, non-governmental scientifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Slime Mold
Slime mold or slime mould is an informal name given to several kinds of unrelated eukaryotic organisms with a life cycle that includes a free-living single-celled stage and the formation of spores. Spores are often produced in macroscopic multicellular or multinucleate fruiting bodies which may be formed through aggregation or fusion. Slime molds were formerly classified as fungi but are no longer considered part of that kingdom. Although not forming a single monophyletic clade, they are grouped within the paraphyletic group Protista. More than 900 species of slime mold occur globally. Their common name refers to part of some of these organisms' life cycles where they can appear as gelatinous "slime". This is mostly seen with the Myxogastria, which are the only macroscopic slime molds. Most slime molds are smaller than a few centimetres, but some species may reach sizes up to several square metres and masses up to 20 kilograms. They feed on microorganisms that live in ...

Didymium Wildpretii
''Didymium wildpretii'' is a species of slime mold which feeds on the decaying remains of various species of cacti. It was first described in 2007 and has been found across Mexico and the Canary Islands, but may be present where other cacti grow. Its sporocarps are short (0.1–0.7 mm tall); their sporotheca is pale yellow with an orange stalk and their spores have a diameter of 7.5 μm. When grown on agar, it completes its life cycle in 28–56 days. It grows on basic media with a pH of 7.8–10.0, with optimum growth occurring at 8.5–9.4. The species was named after Wolfredo Wildpret de la Torre, an expert in the flora of the Canary Islands. Hosts ''Didymium wildpretii'' is known to grow on species of the globose cacti ''Echinocactus platyacanthus'', ''Mammillaria carnea'' and ''Ferocactus latispinus''; the opuntioid cacti ''Opuntia depressa'', '' O. maxima'', '' O. pilifera'' and '' O. tomentosa'') and the columnar cacti (''Myrtillocactus geometrizans'', '' P ...

Myxogastria
Myxogastria/Myxogastrea (myxogastrids, International Code of Zoological Nomenclature, ICZN) or Myxomycetes (International Code of Nomenclature for algae, fungi, and plants, ICN), is a Class (biology), class of slime molds that contains 5 order (biology), orders, 14 family (biology), families, 62 genera, and 888 species. They are colloquially known as the ''plasmodial'' or ''acellular'' slime moulds. All species pass through several, very different morphology (biology), morphologic phases, such as microscopic individual cells, slimy amorphous organisms visible with the naked eye and conspicuously shaped fruit body, fruit bodies. Although they are monocellular, they can reach immense widths and weights: in extreme cases they can be up to across and weigh up to . The class Myxogastria is distributed worldwide, but it is more common in temperate regions where it has a higher biodiversity than in polar regions, the subtropics or tropics. They are mainly found in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Amoebozoa Genera
Amoebozoa is a major taxonomic group containing about 2,400 described species of amoeboid protists, often possessing blunt, fingerlike, lobose pseudopods and tubular mitochondrial cristae. In traditional and currently no longer supported classification schemes, Amoebozoa is ranked as a phylum within either the kingdom Protista or the kingdom Protozoa. In the classification favored by the International Society of Protistologists, it is retained as an unranked "supergroup" within Eukaryota. Molecular genetic analysis supports Amoebozoa as a monophyletic clade. Modern studies of eukaryotic phylogenetic trees identify it as the sister group to Opisthokonta, another major clade which contains both fungi and animals as well as several other clades comprising some 300 species of unicellular eukaryotes. Amoebozoa and Opisthokonta are sometimes grouped together in a high-level taxon, variously named Unikonta, Amorphea or Opimoda. Amoebozoa includes many of the best-known amoeboid organis ...
