Magnus Lidén
Magnus Lidén (born 1951) is a Swedish systematic botanist. Lidén received a PhD in systematic botany from University of Gothenburg in 1986, where he stayed until 1997. He was the director of the Uppsala Botanic Gardens from 1998 – 2003. Since 2004, he has been a researcher at the department of Systematic Biology at the Evolutionary Biology Center of Uppsala University. Lidén is best known for his studies on the plant family Fumariaceae (the bleeding heart family), and the genus ''Dionysia'' (cushion primroses). His research has taken him to the Mediterranean, Central Asia, Iran, and the Sino-Himalayan area (southwest China and northeast India). Lidén has also worked on species concepts, evolutionary ontology, and biological nomenclature Nomenclature codes or codes of nomenclature are the various rulebooks that govern the naming of living organisms. Standardizing the Binomial nomenclature, scientific names of biological organisms allows researchers to discuss findings (i ...

Swedish People
Swedes (), or Swedish people, are an ethnic group native to Sweden, who share a common ancestry, Culture of Sweden, culture, History of Sweden, history, and Swedish language, language. They mostly inhabit Sweden and the other Nordic countries, Swedish-speaking population of Finland, in particular, neighboring Finland, where they are an officially recognized minority, with Swedish being one of the official languages of the country, and with a substantial Swedish diaspora, diaspora in other countries, especially the Swedish Americans, United States. Etymology The English term "Swede" has been attested in English since the late 16th century and is of Middle Dutch or Middle Low German origin. In Swedish language, Swedish, the term is ''svensk'', which is from the name of ''svear'' (or Swedes), the people who inhabited Svealand in eastern central Sweden, and were listed as ''Suiones'' in Tacitus' history ''Germania (book), Germania'' from the first century AD. The term is believed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genus
Genus (; : genera ) is a taxonomic rank above species and below family (taxonomy), family as used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants of an ancestral taxon are grouped together (i.e. Phylogeneti ...

Living People
Purpose: Because living persons may suffer personal harm from inappropriate information, we should watch their articles carefully. By adding an article to this category, it marks them with a notice about sources whenever someone tries to edit them, to remind them of WP:BLP (biographies of living persons) policy that these articles must maintain a neutral point of view, maintain factual accuracy, and be properly sourced. Recent changes to these articles are listed on Special:RecentChangesLinked/Living people. Organization: This category should not be sub-categorized. Entries are generally sorted by family name In many societies, a surname, family name, or last name is the mostly hereditary portion of one's personal name that indicates one's family. It is typically combined with a given name to form the full name of a person, although several give ....

1951 Births
Events January * January 4 – Korean War: Third Battle of Seoul – Chinese and North Korean forces capture Seoul for the second time (having lost the Second Battle of Seoul in September 1950). * January 9 – The Government of the United Kingdom announces abandonment of the Tanganyika groundnut scheme for the cultivation of peanuts in the Tanganyika Territory, with the writing off of £36.5M debt. * January 11 – In the U.S., a top secret report is delivered to U.S. President Truman by his National Security Resources Board, urging Truman to expand the Korean War by launching "a global offensive against communism" with sustained bombing of Red China and diplomatic moves to establish "moral justification" for a U.S. nuclear attack on the Soviet Union. The report will not not be declassified until 1978. * January 15 – In a criminal court in West Germany, Ilse Koch, The "Witch of Buchenwald", wife of the commandant of the Buchenwald concentration camp, is sentenced to li ...

Biological Nomenclature
Nomenclature codes or codes of nomenclature are the various rulebooks that govern the naming of living organisms. Standardizing the Binomial nomenclature, scientific names of biological organisms allows researchers to discuss findings (including the discovery of new species). As the study of biology became increasingly specialized, specific codes were adopted for different types of organism. To an end-user who only deals with names of species, with some awareness that species are assignable to Genus, genera, family (biology), families, and other Linnaean taxonomy, taxa of higher ranks, it may not be noticeable that there is more than one code, but beyond this basic level these are rather different in the way they work. Binomial Nomenclature In Taxonomy (biology), taxonomy, binomial nomenclature ("two-term naming system"), also called binary nomenclature, is a formal system of naming species of living things by giving each a name composed of two parts, both of which use Lat ...

Ontology
Ontology is the philosophical study of existence, being. It is traditionally understood as the subdiscipline of metaphysics focused on the most general features of reality. As one of the most fundamental concepts, being encompasses all of reality and every entity within it. To articulate the basic structure of being, ontology examines the commonalities among all things and investigates their classification into basic types, such as the Theory of categories, categories of particulars and Universal (metaphysics), universals. Particulars are unique, non-repeatable entities, such as the person Socrates, whereas universals are general, repeatable entities, like the color ''green''. Another distinction exists between Abstract and concrete, concrete objects existing in space and time, such as a tree, and abstract objects existing outside space and time, like the number 7. Systems of categories aim to provide a comprehensive inventory of reality by employing categories such as Substance t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evolution
Evolution is the change in the heritable Phenotypic trait, characteristics of biological populations over successive generations. It occurs when evolutionary processes such as natural selection and genetic drift act on genetic variation, resulting in certain characteristics becoming more or less common within a population over successive generations. The process of evolution has given rise to biodiversity at every level of biological organisation. The scientific theory of evolution by natural selection was conceived independently by two British naturalists, Charles Darwin and Alfred Russel Wallace, in the mid-19th century as an explanation for why organisms are adapted to their physical and biological environments. The theory was first set out in detail in Darwin's book ''On the Origin of Species''. Evolution by natural selection is established by observable facts about living organisms: (1) more offspring are often produced than can possibly survive; (2) phenotypic variatio ...

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southwest China
Southwestern China () is a region in the People's Republic of China. It consists of five provincial administrative regions, namely Chongqing, Sichuan, Guizhou, Yunnan, and Xizang. Geography Southwestern China is a rugged and mountainous region, transitioning between the Tibetan Plateau to the west and the Chinese coastal hills (东南丘陵) and plains to the east. Key geographic features in the region include the Hengduan Mountains in the west, the Sichuan Basin in the northeast, and the karstic Yungui Plateau in the east. The majority of the region is drained by the Yangtze River, which forms the Three Gorges in the northeast of the region. The narrowest concept of Southwestern China consists of Sichuan, Chongqing, Yunnan, and Guizhou, while wider definitions often include Guangxi and western portions of Hunan. The official government definition of Southwestern China includes the core provinces of Sichuan, Chongqing, Yunnan, and Guizhou, in addition to the Tibet Autonomou ...

Dionysia (plant)
''Dionysia'' is a genus containing 61 species of flowering plants in the family (biology), family Primulaceae. They are small, cushion-forming alpine plant, alpines native plant, native to mountains of Iran, Iraq, Turkey, sauth Turkmenistan, northwestern Pakistan, Tajikistan, Afghanistan and parts of Oman. They are usually evergreen perennial plant, perennials with felted leaves, covered with bright yellow or pink, five-petalled flowers in spring. They are often difficult to cultivate if the correct conditions are not provided. Most species of ''Dionysia'' are cushion plants that grow in dry mountain environments, but some species are taller and prefer moist environments. In many species, the leaves are covered with an aromatic wax. The leaves are very drought resistant in some species and are reinforced with stone cells (Sclereid, sclerids) either around the nerves or freely in the leaf tissue. These species blooms profusely in early spring with yellow, purple, violet or pink flo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fumariaceae
Fumarioideae is a subfamily of the family Papaveraceae (the poppy family). It was formerly treated as a separate family, the Fumariaceae (the fumitory, fumewort or bleeding-heart family). It consists of about 575 species of herbaceous plants in 20 genera, native to the Northern Hemisphere and South Africa. The largest genus is ''Corydalis'' (with 470 species). Description Flower shape Plants in the fumitory subfamily are easily recognised by their peculiar flowers with two dissimilar pairs of petals. One or both of the outer petals is usually spurred, and the inner petals are connected at tip. There are two types of flowers. A given genus has one type or the other. '' Dicentra'' has flowers with two planes of symmetry, and ''Corydalis'' has flowers with one plane of symmetry (zygomorphic Floral symmetry describes whether, and how, a flower, in particular its perianth, can be divided into two or more identical or mirror-image parts. Uncommonly, flowers may have no axis of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
