Teuvoa
''Teuvoa'' is a genus of lichen-forming fungi in the family Megasporaceae. The genus was circumscribed in 2013 by Mohammad Sohrabi and Steven Leavitt with ''Teuvoa uxoris'' assigned as the type species. The genus was segregated from the large genus '' Aspicilia'' after molecular phylogenetic analysis revealed that the ''Aspicilia uxoris'' species group formed a monophyletic clade that represented an independent lineage within the Megasporaceae. Three species were initially placed in the genus; two additional species from China were added in 2018. ''Teuvoa'' is distinguished from ''Aspicilia'' by its small ascospores and conidia (the latter measuring 5–8 μm), and the lack of secondary metabolites. The genus name honours Finnish lichenologist Teuvo Ahti, "one of the prominent lichen taxonomists of the 20th century".

Megasporaceae
Megasporaceae are a family of fungi belonging to the order Pertusariales. Taxa are lichenized with green algae, and grow on rocks, often in maritime climates close to fresh water. Phylogenetic analysis has shown that this family is related to the Pertusariaceae, another family of lichens. The genus ''Aspicilia'' was moved here from the Hymeneliaceae. Genera Genera of this family include: * ''Aspicilia'' – ca. 200 spp. * '' Aspiciliella'' – 2 spp. * '' Circinaria'' – 31 spp. * '' Lobothallia'' – 17 spp. * '' Megaspora'' – 4 spp. * '' Oxneriaria'' – 9 spp. * '' Sagedia'' – 12 spp. * ''Teuvoa ''Teuvoa'' is a genus of lichen-forming fungi in the family Megasporaceae.

Teuvo Ahti
Teuvo ("Ted") Tapio Ahti (born 1934) is a Finnish botanist and lichenologist. He has had a long career at the University of Helsinki that started in 1963, and then following his retirement in 1997, at the Botanical Museum of the Finnish Museum of Natural History. Known as a specialist of the lichen family Cladoniaceae, Ahti has published more than 280 scientific publications. A ''Festschrift'' was dedicated to him in 1994, and in 2000 he was awarded the prestigious Acharius Medal for lifetime contributions to lichenology. Education and career Ahti started developing an interest in botany at the age of 15, when he worked on a class project involving collecting 100 species of plants. His attention turned to lichens when a classmate who had worked for Veli Räsänen pointed them out during a birdwatching excursion in Helsinki. His interest was further fuelled when a couple of years later, he had to pass a test on identification of forest floor lichens and bryophytes as part of an ...

Lineage (evolution)
An evolutionary lineage is a temporal series of populations, organisms, cells, or genes connected by a continuous line of descent from ancestor to descendant.The Oxford English Dictionary defines biological lineage as "a sequence of species each of which is considered to have evolved from its predecessorOED definition of lineage/ref> Lineages are subsets of the evolutionary tree of life. Lineages are often determined by the techniques of molecular systematics.

Secondary Metabolite
Secondary metabolites, also called specialised metabolites, toxins, secondary products, or natural products, are organic compounds produced by any lifeform, e.g. bacteria, fungi, animals, or plants, which are not directly involved in the normal growth, development, or reproduction of the organism. Instead, they generally mediate ecological interactions, which may produce a selective advantage for the organism by increasing its survivability or fecundity. Specific secondary metabolites are often restricted to a narrow set of species within a phylogenetic group. Secondary metabolites often play an important role in plant defense against herbivory and other interspecies defenses. Humans use secondary metabolites as medicines, flavourings, pigments, and recreational drugs. The term secondary metabolite was first coined by Albrecht Kossel, a 1910 Nobel Prize laureate for medicine and physiology in 1910. 30 years later a Polish botanist Friedrich Czapek described secondary metabolit ...

Micrometre
The micrometre ( international spelling as used by the International Bureau of Weights and Measures; SI symbol: μm) or micrometer (American spelling), also commonly known as a micron, is a unit of length in the International System of Units (SI) equalling (SI standard prefix "micro-" = ); that is, one millionth of a metre (or one thousandth of a millimetre, , or about ). The nearest smaller common SI unit is the nanometre, equivalent to one thousandth of a micrometre, one millionth of a millimetre or one billionth of a metre (). The micrometre is a common unit of measurement for wavelengths of infrared radiation as well as sizes of biological cells and bacteria, and for grading wool by the diameter of the fibres. The width of a single human hair ranges from approximately 20 to . The longest human chromosome, chromosome 1, is approximately in length. Examples Between 1 μm and 10 μm: * 1–10 μm – length of a typical bacterium * 3–8 μm – width of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
