Rolf Dahlgren
Rolf Martin Theodor Dahlgren (7 July 1932 – 14 February 1987) was a Swedish- Danish botanist and professor at the University of Copenhagen from 1973 to his death. Life Dahlgren was born in Örebro on 7 July 1932 to apothecary Rudolf Dahlgren and wife Greta née Dahlstrand. He took his MSc degree in Biology in (1955) and PhD degree in Botany in (1963) at Lund University. He was killed in a car crash in Scania, Sweden on 14 February 1987. Career He continued working on South African plants during expeditions in 1956-57 and 1965–66, while affiliated with the ''Botanical Museum'' in Lund as ''docent''. In 1973, he became professor of botany at the University of Copenhagen. Here, he developed his system of Angiosperm classification, based on many more characters simultaneously than previous systems, most notably many chemical plant traits (see also chemotaxonomy). Although the system was first presented in Danish, it rapidly gained widespread acceptance, particularly due t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Örebro
Örebro ( , ) is the sixth-largest city in Sweden, the seat of Örebro Municipality, and capital of the Örebro County.

Chemotaxonomy
Merriam-Webster defines ''chemotaxonomy'' as the method of biological classification based on similarities and dissimilarity in the structure of certain compounds among the organisms being classified. Advocates argue that, as proteins are more closely controlled by genes and less subjected to natural selection than the anatomical features, they are more reliable indicators of genetic relationships. The compounds studied most are proteins, amino acids, nucleic acids, peptides etc. Physiology is the study of working of organs in a living being. Since working of the organs involves chemicals of the body, these compounds are called biochemical evidences. The study of morphological change has shown that there are changes in the structure of animals which result in evolution. When changes take place in the structure of a living organism, they will naturally be accompanied by changes in the physiological or biochemical processes. John Griffith Vaughan was one of the pioneers of che ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Botaniska Notiser
''Botaniska Notiser'' was a Swedish scientific periodical concerning botany, issued in Lund, by Societate botanica Lundensi or unds Botaniska Förening It was published from 1839 to 1980, when it fused with ''Botanisk Tidsskrift'', '' Friesia'' and ''Norwegian Journal of Botany'' to form the ''Nordic Journal of Botany''. In 2001, the journal reappeared as a regional journal for botany in south Sweden. Monographs were published in a parallel series, ''Botaniska Notiser Supplement'' (1947-1954). This series was fused in 1980 with '' Dansk Botanisk Arkiv'' under the name '' Opera Botanica'', which since then has been the monograph series of the ''Nordic Journal of Botany''.

The genus includes more than 350 species, distributed through the Neotropical, Afrotropical, Indomalayan, and Australasian realms. Overview The genus includes species of evergreen trees, distributed mostly in tropical and subtropical regions of South America, India, China, Java, New Guinea, Africa, Madagascar, and Mauritius, with seven species in Southern Africa. Common in the canopy, they grow up to 60 m, or as subcanopy trees in the succession climax species in tropical, lower temperate, or subtropical broadleaved forests. They are found in low-elevation evergreen forests and littoral rainforests, on all type of soils. The seeds are readily dispersed by fruit-eating birds, and seedlings and saplings have been recorded from other habitats where they are unlikely to develop to maturity. The genus name ''Cryptocarya'' is from a Greek word ''krypto'' meaning to hide, ''karya'' meaning a wal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Germany
Germany, officially the Federal Republic of Germany (FRG),, is a country in Central Europe. It is the most populous member state of the European Union.

It borders Denmark to the north, Poland and Czechia to the east, Austria and Switzerland to the south, and France, Luxembourg, Belgium, and the Netherlands to the west. The nation's capital and most populous city is Berlin and its main financial centre is Frankfurt; the largest urban area is the Ruhr. Settlement in what is now Germany began in the Lower Paleolithic, with various tribes inhabiting it from the Neolithic onward, chiefly the Celts. Various Germanic tribes have inhabited the northern parts of modern Germany since classical antiquity. A region named Germania was documented before AD 100. In 962, the Kingdom of Germany formed the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berlin
Berlin is Capital of Germany, the capital and largest city of Germany, both by area and List of cities in Germany by population, by population.
