Vsevolod Savich
Vsevolod Pavlovich Savich (; 19 February 1885 – 25 May 1972) was a Soviet lichenologist. He headed the Section of Cryptogamic Plants of the Komarov Botanical Institute of the Academy of Sciences of the Soviet Union. Savich died in Leningrad in 1972. The crustose lichen Crustose lichens are lichens that form a crust which strongly adheres to the Substrate (biology), substrate (soil, rock, tree bark, etc.), making separation from the substrate impossible without destruction.

Elke Mackenzie
Elke Mackenzie (11 September 1911 – 18 January 1990), born Ivan Mackenzie Lamb, was a British polar explorer and botanist who specialised in the field of lichenology. Early life Mackenzie was born in Clapham, London, on 11 September 1911. Mackenzie's family moved to Scotland while she was a child, and she was enrolled in the Edinburgh Academy. After her graduation in 1929, she attended Edinburgh University. She earned her B.Sc. with Honors in Botany in 1933. She received a scholarship from the German Academic Exchange Service, and continued doing research in botany at the University of Munich and the University of Würzburg.Llano, G. (1991). I.

Host (biology)
In biology and medicine, a host is a larger organism that harbours a smaller organism; whether a parasite, parasitic, a mutualism (biology), mutualistic, or a commensalism, commensalist ''guest'' (symbiont). The guest is typically provided with nourishment and shelter. Examples include animals playing host to parasitic worms (e.g. nematodes), cell (biology), cells harbouring pathogenic (disease-causing) viruses, a Fabaceae, bean plant hosting mutualistic (helpful) Rhizobia, nitrogen-fixing bacteria. More specifically in botany, a host plant supplies nutrient, food resources to micropredators, which have an evolutionarily stable strategy, evolutionarily stable relationship with their hosts similar to ectoparasitism. The host range is the collection of hosts that an organism can use as a partner. Symbiosis Symbiosis spans a wide variety of possible relationships between organisms, differing in their permanence and their effects on the two parties. If one of the partners in an ass ...

Lichenicolous Fungus
A lichenicolous fungus is a parasitic fungus that only lives on lichen as the host. A lichenicolous fungus is not the same as the fungus that is the component of the lichen, which is known as a lichenized fungus. They are most commonly specific to a given fungus as the host, but they also include a wide range of pathogens, saprotrophs, and commensals. It is estimated there are 3000 species of lichenicolous fungi. More than 1800 species are already described among the Ascomycota and Basidiomycota.Lichenicolous Fungi: Interactions, Evolution, and Biodiversity, Lawrey, James D.; Diederich, Paul. The Bryologist 106(1), pp. 80 120, 2003/ref> More than 95% of lichenicolous fungi described as of 2003 are ascomycetes, in 7 class (biology), classes and 19 order (biology), orders. Although basidiomycetes have less than 5% of lichenicolous lichen species, they represent 4 classes and 8 orders. Many lichenicolous species have yet to be assigned a phylogenetic position as of 2003. See also * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lichen Species
A lichen ( , ) is a composite organism that arises from algae or cyanobacteria living among filaments of multiple fungi species in a mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. Lichens have properties different from those of their component organisms. They come in many colors, sizes, and forms and are sometimes plant-like, but are not s. They may have tiny, leafless branches (); flat leaf-like structures ( |
Taxa Named By Vsevolod Savich
In biology, a taxon (back-formation from ''taxonomy''; plural taxa) is a group of one or more populations of an organism or organisms seen by taxonomists to form a unit. Although neither is required, a taxon is usually known by a particular name and given a particular ranking, especially if and when it is accepted or becomes established. It is very common, however, for taxonomists to remain at odds over what belongs to a taxon and the criteria used for inclusion. If a taxon is given a formal scientific name, its use is then governed by one of the nomenclature codes specifying which scientific name is correct for a particular grouping. Initial attempts at classifying and ordering organisms (plants and animals) were set forth in Carl Linnaeus's Linnaean taxonomy, system in ''Systema Naturae'', 10th edition (1758), as well as an unpublished work by Bernard de Jussieu, Bernard and Antoine Laurent de Jussieu. The idea of a unit-based system of biological classification was first mad ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
