Metus (fungus)
''Metus'' is a genus of three species of lichenized fungi in the family Cladoniaceae. The genus was circumscription (taxonomy), circumscribed by lichenologists David John Galloway and Peter Wilfred James in 1987, with ''Metus conglomeratus'' as the type species. All three species are found in the Southern Hemisphere. Galloway and James suggested a placement of the genus in Cladoniaceae, a classification (biology), classification that was later supported with phylogenetic analysis.

Peter Wilfred James
Peter Wilfred James (1930–2014) was an English botanist and lichenologist. He was a pioneer in the study of lichens as environmental indicators, especially of atmospheric pollution. Early life and education Peter W. James grew up in Sutton Coldfield, which was then a rural suburb of Birmingham and his interests in natural history and exploring the countryside were encouraged by his older sister. His father was a headteacher. James attended Bishop Vesey's Grammar School Bishop Vesey's Grammar School (BVGS) is a selective state grammar school with academy status in Sutton Coldfield, West Midlands, England. Founded in 1527, it is one of the oldest schools in Britain, the oldest state school in the West Midlan ... in Warwickshire from 1943 until 1949. He was awarded a State Scholarship (UK), state scholarship that supported his university study. He graduated with a First class B.Sc. in botany from the University of Liverpool in 1952 with a minor in zoology (1951). There he ...

Taxa Described In 1987
In biology, a taxon (back-formation from ''taxonomy''; : 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, especially in the context of rank-based (" Linnaean") nomenclature (much less so under phylogenetic nomenclature). 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 presumably set forth in prehistoric times by hunter-gatherers, as suggested by the fairly sophisticated folk taxonomies. Much later, Aristotle, and later still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lichen Genera
A lichen ( , ) is a hybrid colony (biology), colony of algae or cyanobacteria living symbiotically among hypha, filaments of multiple fungus species, along with yeasts and bacteria embedded in the cortex or "skin", in a mutualism (biology), mutualistic relationship.Introduction to Lichens – An Alliance between Kingdoms . University of California Museum of Paleontology. . Lichens are the lifeform that first brought the term symbiosis (as ''Symbiotismus'') into biological context. Lichens have since been recognized as important actors in nutrient cycling and producers which many higher trophic feeders feed on, such as reindeer, gastropods, nematodes, mites, and springtails. Lichens have properties different from those of their component organisms. They come in man ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Classification (biology)
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon), and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, having developed a ranked system known as Linnaean taxonomy for categorizing organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolutionary relationships among organisms, both li ...

Type Species
In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological Type (biology), type wiktionary:en:specimen, specimen (or specimens). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the International Code of Nomenclature for algae, fungi, and plants, code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name with that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have suc ...

David John Galloway
David John Galloway , FRSNZ (7 May 1942 – 6 December 2014) was a biochemist, botanist, and lichenologist. Biography Galloway grew up in Invercargill. After graduation from Southland Boys' High School, he studied at the University of Otago. As an undergraduate he assisted James Murray, the first New Zealand lichenologist of the twentieth century, and this experience influenced the direction of his scientific career. There he graduated in 1963 with B.Sc., in 1965 with M.Sc., and in 1972 with Ph.D. — all three degrees in biochemistry. At the University of Otago, he was from 1963 to 1965 a fellow and tutor at Knox College and from 1965 to 1968 an assistant lecturer in biochemistry. He became in 1969 a scientific officer in the Applied Biochemistry Division of New Zealand's Department of Scientific and Industrial Research (DSIR) in Palmerston North. He participated in the 1970 Three Kings Islands expedition as a botanist. He transferred in 1973 to the Botany Division DSIR i ...

Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. For example, if we determine that species X, Y, and Z belong in genus A, and species T, U, V, and W belong in genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecu ...

Cladoniaceae
The Cladoniaceae are a family of lichen-forming fungi in the order Lecanorales, comprising about 560 species distributed amongst 18 genera. This family is one of the largest among lichen-forming fungi and is globally distributed, from Arctic tundra to tropical rainforests, favouring humid environments while being intolerant of arid conditions. Molecular phylogenetics has significantly advanced the understanding of their complex taxonomic history, revealing intricate evolutionary relationships and leading to a refined classification. Notable members include reindeer moss and cup lichens of the genus '' Cladonia'', which consist of about 500 species and forms a significant part of the diet for large mammals in taiga and tundra ecosystems. A distinctive feature of many Cladoniaceae species is their dimorphic thallus: a scaly or crust-like form and a (shrub-like) secondary form known as a podetium or . These lichens typically grow on soil, decaying wood, or tree trunks, with a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
