Gen-ichi Koidzumi
was a Japanese botanist, author of several papers and monographs on phytogeography including work on roses and Amygdaloideae (Rosaceae), maples (Aceraceae), mulberries (the genus '' Morus''), and many other plants. His name is sometimes transliterated as Gen’ichi or Gen-Iti, or as Koizumi. Biography Gen-ichi Koidzumi was born in Yonezawa in Yamagata Prefecture in 1883. After graduating from the Sapporo Agricultural College, he studied biology at Tokyo Imperial University from 1905, continuing his studies there under Matsumura Jinzō, and receiving his doctorate in 1916. In 1919, he was appointed assistant professor at Kyoto Imperial University, where he remained (other than for a tour of the herbaria of Europe and the United States from 1925 to 1927) until his retirement in 1943; he was promoted to full professor in 1936. In 1932, he founded the Societas Phytogeographica and the journal '' Acta Phytotaxonomica et Geobotanica''. Koidzumi died in his hometown of Yonezawa in 19 ...

Endemic Flora Of Japan
Endemism is the state of a species being found only in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can also be referred to as an ''endemism'' or, in scientific literature, as an ''endemite''. Similarly, many species found in the Western ghats of India are examples of endemism. Endemism is an important concept in conservation biology for measuring biodiversity in a particular place and evaluating the risk of extinction for species. Endemism is also of interest in evolutionary biology, because it provides clues about how changes in the environment cause species to undergo range shifts (potentially expanding their range into a larger area or becomin ...

Flora Of The Bonin Islands
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is ''funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) was ...

Cirsium
''Cirsium'' is a genus of Perennial plant, perennial and Biennial plant, biennial flowering plants in the Asteraceae, one of several genera known commonly as thistles. They are more precisely known as plume thistles. These differ from other thistle genera (''Carduus'', ''Silybum'' and ''Onopordum'') in having a seed with a Pappus (flower structure), pappus of feathered hairs on their achenes. The other genera have a pappus of simple unbranched hairs. They are mostly native to Eurasia and northern Africa, with about 60 species from North America (although several species have been introduced outside their native ranges). The type (biology), lectotype species of the genus is ''Cirsium heterophyllum'' (L.) Hill. ''Cirsium'' thistles are known for their effusive flower heads, usually purple, rose or pink, also yellow or white. The radially symmetrical disc flowers are at the end of the branches and are visited by many kinds of insects, featuring a generalised pollination syndrome. Th ...

Japanese Red List
The Japanese is the Japanese domestic counterpart to the IUCN Red List of Threatened Species. The national Red List is compiled and maintained by the Ministry of the Environment, alongside a separate Red List for marine organisms. Similarly drawing on the relevant scientific authorities, NGOs, and local governments, the Ministry of the Environment also prepares and publishes a that provides further information on species and habitats. The first Red List was published by the then Environmental Agency as part of the first Red Data Book in 1991; in 2020, the fifth edition of the fourth version of the Red List was published. In line with the Marine Biodiversity Conservation Strategy, decided upon by the Ministry in 2011, in 2017 the first Marine Life Red List was published, excluding species subject to international agreements, such as those within the remit of the Western and Central Pacific Fisheries Commission (WCPFC) (''e.g.'', Pacific bluefin tuna) and International Whaling Com ...

Ministry Of The Environment (Japan)
The is a Cabinet-level ministry of the government of Japan responsible for global environmental conservation, pollution control, and nature conservation. The ministry was formed in 2001 from the sub-cabinet level Environmental Agency established in 1971. The Minister of the Environment is a member of the Cabinet of Japan and is chosen by the Prime Minister, usually from among members of the Diet. In March 2006, the then-Minister of the Environment Yuriko Koike, created a '' furoshiki'' cloth to promote its use in the modern world. In August 2011, the Cabinet of Japan approved a plan to establish a new energy watchdog under the Environment Ministry, and the Nuclear Regulation Authority was founded on September 19, 2012.

Extinction
Extinction is the termination of an organism by the death of its Endling, last member. A taxon may become Functional extinction, functionally extinct before the death of its last member if it loses the capacity to Reproduction, reproduce and recover. As a species' potential Range (biology), range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxon, Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the Fossil, fossil record) after a period of apparent absence. Over five billion species are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryotes globally, possibly many times more if microorganisms are included. Notable extinct animal species include Dinosaur, non-avian dinosaurs, Machairodontinae, saber-toothed cats, and mammoths. Through evolution, species arise through the process of specia ...

Thistle
Thistle is the common name of a group of flowering plants characterized by leaves with sharp spikes on the margins, mostly in the family Asteraceae. Prickles can also occur all over the planton the stem and on the flat parts of the leaves. These prickles protect the plant from herbivores. Typically, an involucre with a clasping shape similar to a cup or urn subtends each of a thistle's flower heads. The typically feathery pappus of a ripe thistle flower is known as thistle-down. The spininess varies considerably by species. For example, '' Cirsium heterophyllum'' has very soft spines while '' Cirsium spinosissimum'' is the opposite. Typically, species adapted to dry environments are more spiny. The term thistle is sometimes taken to mean precisely those plants in the tribe Cardueae (synonym: Cynareae), especially the genera '' Carduus'', '' Cirsium'', and '' Onopordum''. However, plants outside this tribe are sometimes also called thistles. Biennial thistles are partic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Species Description
A species description is a formal scientific description of a newly encountered species, typically articulated through a scientific publication. Its purpose is to provide a clear description of a new species of organism and explain how it differs from species that have been previously described or related species. For a species to be considered valid, a species description must follow established guidelines and naming conventions dictated by relevant nomenclature codes. These include the International Code of Zoological Nomenclature (ICZN) for animals, the International Code of Nomenclature for algae, fungi, and plants (ICN) for plants, and the International Committee on Taxonomy of Viruses (ICTV) for viruses. A species description often includes photographs or other illustrations of type material and information regarding where this material is deposited. The publication in which the species is described gives the new species a formal scientific name. Some 1.9 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
