Taxonomy Of The Orchid Family
The taxonomy of the Orchidaceae ( orchid family) has evolved slowly during the last 250 years, starting with Carl Linnaeus who in 1753 recognized eight genera.Carolus Linnaeus (Carl von Linné). 1753. ''Species Plantarum'', 1st edition, vol. 2, pages 939-954. Holmiae: Impensis Laurentii Salvii (Lars Salvius). (A facsimile with an introduction by William T. Stearn was published by the Ray Society in 1957). (See ''External links'' below). De Jussieu recognized the Orchidaceae as a separate family in his Genera Plantarum in 1789.Antoine Laurent de Jussieu. 1789. "ORCHIDEAE" pages 64-66. In: ''Genera plantarum: secundum ordines naturales disposita,···'' (See ''External links'' below). Olof Swartz recognized 25 genera in 1800.Olof Swartz. 1800. "Afhandling om Orchidernes Slägter och deras Systematiska indelning". ''Kongliga vetenskaps academiens nya handlingar'' 21:115-139. (See ''External links'' below). Louis Claude Richard provided us in 1817 with the descriptiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haeckel Orchidae
Ernst Heinrich Philipp August Haeckel (; 16 February 1834 – 9 August 1919) was a German zoologist, naturalist, eugenicist, philosopher, physician, professor, marine biologist and artist. He discovered, described and named thousands of new species, mapped a genealogical tree relating all life forms and coined many terms in biology, including ''ecology'', ''phylum'', ''phylogeny'', and ''Protista.'' Haeckel promoted and popularised Charles Darwin's work in Germany and developed the influential but no longer widely held recapitulation theory ("ontogeny recapitulates phylogeny") claiming that an individual organism's biological development, or ontogeny, parallels and summarises its species' evolutionary development, or phylogeny. The published artwork of Haeckel includes over 100 detailed, multi-colour illustrations of animals and sea creatures, collected in his ''Kunstformen der Natur'' ("Art Forms of Nature"), a book which would go on to influence the Art Nouveau artistic move ...

Academic Publishing
Academic publishing is the subfield of publishing which distributes academic research and scholarship. Most academic work is published in academic journal articles, books or theses. The part of academic written output that is not formally published but merely printed up or posted on the Internet is often called "grey literature". Most scientific and scholarly journals, and many academic and scholarly books, though not all, are based on some form of peer review or editorial refereeing to qualify texts for publication. Peer review quality and selectivity standards vary greatly from journal to journal, publisher to publisher, and field to field. Most established academic disciplines have their own journals and other outlets for publication, although many academic journals are somewhat interdisciplinary, and publish work from several distinct fields or subfields. There is also a tendency for existing journals to divide into specialized sections as the field itself becomes more spec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sample (statistics)
In statistics, quality assurance, and survey methodology, sampling is the selection of a subset (a statistical sample) of individuals from within a statistical population to estimate characteristics of the whole population. Statisticians attempt to collect samples that are representative of the population in question. Sampling has lower costs and faster data collection than measuring the entire population and can provide insights in cases where it is infeasible to measure an entire population. Each observation measures one or more properties (such as weight, location, colour or mass) of independent objects or individuals. In survey sampling, weights can be applied to the data to adjust for the sample design, particularly in stratified sampling. Results from probability theory and statistical theory are employed to guide the practice. In business and medical research, sampling is widely used for gathering information about a population. Acceptance sampling is used to determine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DNA Sequence
DNA sequencing is the process of determining the nucleic acid sequence – the order of nucleotides in DNA. It includes any method or technology that is used to determine the order of the four bases: adenine, guanine, cytosine, and thymine. The advent of rapid DNA sequencing methods has greatly accelerated biological and medical research and discovery. Knowledge of DNA sequences has become indispensable for basic biological research, DNA Genographic Projects and in numerous applied fields such as medical diagnosis, biotechnology, forensic biology, virology and biological systematics. Comparing healthy and mutated DNA sequences can diagnose different diseases including various cancers, characterize antibody repertoire, and can be used to guide patient treatment. Having a quick way to sequence DNA allows for faster and more individualized medical care to be administered, and for more organisms to be identified and cataloged. The rapid speed of sequencing attained with modern D ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Molecular Phylogenetics
Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships. From these analyses, it is possible to determine the processes by which diversity among species has been achieved. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree. Molecular phylogenetics is one aspect of molecular systematics, a broader term that also includes the use of molecular data in taxonomy and biogeography. Molecular phylogenetics and molecular evolution correlate. Molecular evolution is the process of selective changes (mutations) at a molecular level (genes, proteins, etc.) throughout various branches in the tree of life (evolution). Molecular phylogenetics makes inferences of the evolutionary relationships that arise due to molecular evolution and results in the construction of a phylogenetic tree.

Vicki Funk
Vicki Ann Funk (November 26, 1947 – October 22, 2019) was an American botanist and curator at the Smithsonian's National Museum of Natural History, known for her work on members of the composite family (Asteraceae) including collecting plants in many parts of the world, as well as her synthetic work on phylogenetics and biogeography. Biography Funk was born on November 26, 1947, in Owensboro, Kentucky, to Edwin Joseph and Betty Ann (''née'' Massenburg) Funk. She had two brothers, Edwin Jr. and Jared Kirk. She grew up in Owensboro and at a few United States Air Force bases before she was in elementary school. Funk studied biology and history at Murray State University in Kentucky and received a Bachelor of Science (BS) degree in 1969. She had wanted to attend medical school, but decided against it after volunteering at a hospital one summer. After graduating, she lived and worked part-time in Germany for two years, then returned to the United States to teach high school for ...

Leslie Andrew Garay
Leslie Andrew Garay (August 6, 1924 - August 19, 2016), born Garay László András, was an American botanist. He was the curator of the Oakes Ames Orchid Herbarium at Harvard University, where he succeeded Charles Schweinfurth in 1958. In 1957 he was awarded a Guggenheim Fellowship. Life and work Garay was born in Hungary, and after the Second World War he emigrated first to Canada and then to the United States. He was a taxonomist and collector of orchids, particularly interested in the orchids of tropical America and Southeast Asia. His ideas were influential in orchid taxonomy, and he reorganized several genera, including ''Oncidium''. In addition to reclassification of various species into different genera, he defined a number of new genera including ''Chaubardiella'' in 1969 and '' Amesiella'' in 1972. Publications Among his influential publications were: * ''Venezuelan Orchids Illustrated'', Galfrid C. K. Dunsterville & Leslie A. Garay, Andre Deutsch, London & Amsterd ...

Rudolf Mansfeld
Rudolf Mansfeld (17 January 1901, Berlin – 1960) was a German botanist and agricultural scientist. For more than twenty years, he worked as a curator at the Botanical Garden and Botanical Museum in Berlin-Dahlem. Here he specialized in studies of Orchidaceae (orchids) and Euphorbiaceae (spurges).
