Thismia Kobensis
''Thismia kobensis'' is a species of flowering plant from the ''Thismia'' genus in the myco-heterotrophic family Burmanniaceae. The type and originally only specimen was discovered in Kobe, Japan, in 1992, and preserved without identification, although it was originally assigned to the genus '' Oxygyne''. No new specimens were found in follow-up surveys between 1993 and 1999, and the plant's original habitat was destroyed by land development in 1999. ''T. kobensis'' was declared extinct in 2010 due to habitat loss and deforestation. It was described as a species of ''Thismia'' in 2018. In 2021 the plant was rediscovered some 30 km away from the original location. 20 specimens were found in a conifer plantation. News of the rediscovery was published in 2023.

Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessaril ...

William Griffith (botanist)
William Griffith (4 March 1810 – 9 February 1845) was a British doctor, naturalist, and botanist. Griffith's botanical publications are from India and Burma. After a brief stay in Madras, he was assigned as a Civil Surgeon to Tenasserim, Burma, where he studied local plants and made collecting trips to the Barak River valley in Assam. He explored various parts of Burma, traveling the rivers, including the Irrawadi as far as Rangoon. He visited the highlands of Sikkim, and the region of the Himalayas around Shimla. Subsequently, Griffith was appointed as Civil Surgeon in Malacca, where he died of a parasitic liver disease. Biography William was born at Ham on 4 March 1810, the son of Thomas Griffith. He studied under a private tutor along with brothers and even in his early days, took an interest in botany. He later went to London University where he studied under Robert Brown and John Lindley. He was also influenced by his friend R.H. Solly. He studied briefly at Paris u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Proceedings Of The Linnean Society Of London
The Linnean Society of London is a learned society dedicated to the study and dissemination of information concerning natural history, evolution, and taxonomy. It possesses several important biological specimen, manuscript and literature collections, and publishes academic journals and books on plant and animal biology. The society also awards a number of prestigious medals and prizes. A product of the 18th-century enlightenment, the Society is the oldest extant biological society in the world and is historically important as the venue for the first public presentation of the theory of evolution by natural selection on 1 July 1858. The patron of the society was Queen Elizabeth II. Honorary members include: King Charles III of Great Britain, Emeritus Emperor Akihito of Japan, King Carl XVI Gustaf of Sweden (both of latter have active interests in natural history), and the eminent naturalist and broadcaster Sir David Attenborough.

Myco-heterotrophic
Myco-heterotrophy (from Greek μύκης , "fungus", ἕτερος ', "another", "different" and τροφή ', "nutrition") is a symbiotic relationship between certain kinds of plants and fungi, in which the plant gets all or part of its food from parasitism upon fungi rather than from photosynthesis. A myco-heterotroph is the parasitic plant partner in this relationship. Myco-heterotrophy is considered a kind of cheating relationship and myco-heterotrophs are sometimes informally referred to as "mycorrhizal cheaters". This relationship is sometimes referred to as mycotrophy, though this term is also used for plants that engage in mutualistic mycorrhizal relationships. Relationship between myco-heterotrophs and host fungi Full (or obligate) myco-heterotrophy exists when a non-photosynthetic plant (a plant largely lacking in chlorophyll or otherwise lacking a functional photosystem) gets all of its food from the fungi that it parasitizes. Partial (or facultative) myco-hetero ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burmanniaceae
Burmanniaceae is a family of flowering plants, consisting of 99 species of herbaceous plants in eight genera. Description These plants are annual or perennial herbs, with generally unbranched stems, some lacking leaves. Some members of this family lack chlorophyll and are mycotrophic (also called myco-heterotrophic). The family tends to be saprophytic and even the autotrophic species are all endomycorrhizal and probably at least hemisaprophytic. The family occurs worldwide, with a mostly tropic to subtropical distribution. A number of species are threatened. Taxonomy John Lindley described the family as Burmanniae, with the single genus ''Burmannia'', in 1830. In 1998 the APG I system placed Burmanniaceae as one of five families in the order Dioscoreales, within the monocot clade. The APG II system of 2003, as a result of an extensive study by Caddick and colleagues (2002), using an analysis of three genes, ''rbc''L, ''atp''B and 18S rDNA, in addition to morphological crite ...

Extinct
Extinction is the termination of a kind of organism or of a group of kinds ( taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habitat Loss
Habitat destruction (also termed habitat loss and habitat reduction) is the process by which a natural habitat becomes incapable of supporting its native species. The organisms that previously inhabited the site are displaced or dead, thereby reducing biodiversity and species abundance. Habitat destruction is the leading cause of biodiversity loss. Fragmentation and loss of habitat have become one of the most important topics of research in ecology as they are major threats to the survival of endangered species. Activities such as harvesting natural resources, industrial production and urbanization are human contributions to habitat destruction. Pressure from agriculture is the principal human cause. Some others include mining, logging, trawling, and urban sprawl. Habitat destruction is currently considered the primary cause of species extinction worldwide. Environmental factors can contribute to habitat destruction more indirectly. Geological processes, climate change, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Deforestation
Deforestation or forest clearance is the removal of a forest or stand of trees from land that is then land conversion, converted to non-forest use. Deforestation can involve conversion of forest land to farms, ranches, or urban area, urban use. The most concentrated deforestation occurs in tropical rainforests. About 31% of Earth's land surface is covered by forests at present. This is one-third less than the forest cover before the expansion of agriculture, a half of that loss occurring in the last century. Between 15 million to 18 million hectares of forest, an area the size of Bangladesh, are destroyed every year. On average 2,400 trees are cut down each minute. The Food and Agriculture Organization, Food and Agriculture Organization of the United Nations defines deforestation as the conversion of forest to other land uses (regardless of whether it is human-induced). "Deforestation" and "forest area net change" are not the same: the latter is the sum of all forest losses ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
