Hans Winkler (ornithologist)
Hans Karl Albert Winkler (23 April 1877 – 22 November 1945) was a German botanist. He was Professor of Botany at the University of Hamburg, and a director of that university's Institute of Botany. Winkler coined the term 'heteroploidy' in 1916. He is remembered for coining the term 'genome' in 1920, by making a portmanteau of the words gene and chromosome. He wrote: This may be translated as: "I propose the expression ''Genom'' for the haploid chromosome set, which, together with the pertinent protoplasm, specifies the material foundations of the species ..." Among his experiments was the discovery of chimeras (also chimaeras) by grafting a Deadly Nightshade and tomato plant and observing a shoot which displayed characteristics of both plants. Winkler also worked at the University of Naples, in Italy, where he researched the physiology of the alga ''Bryopsis''. He joined the NSDAP in 1937.Ernst Klee Ernst Klee (15 March 1942, Frankfurt – 18 May 2013, Frankfurt) was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Botanist
Botany, also called , plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word (''botanē'') meaning "pasture", " herbs" "grass", or " fodder"; is in turn derived from (), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes. Botany originated in prehistory as herbalism with the efforts of early humans to identify – and later cultivate – edible, med ...

University Of Naples
The University of Naples Federico II ( it, Università degli Studi di Napoli Federico II) is a public university in Naples, Italy. Founded in 1224, it is the oldest public non-sectarian university in the world, and is now organized into 26 departments. It was Europe's first university dedicated to training secular administrative staff, and is one of the oldest academic institutions in continuous operation.

Ernst Klee
Ernst Klee (15 March 1942, Frankfurt – 18 May 2013, Frankfurt) was a German journalist and author. As a writer on Germany's history, he was best known for his exposure and documentation of medical crimes in Nazi Germany, much of which was concerned with the Action T4 or involuntary euthanasia program. He is the author of ''"The Good Old Days": The Holocaust Through the Eyes of the Perpetrators and Bystanders'' first published in the English translation in 1991. Life and work Klee was first trained as a sanitary and heating technician. Afterwards, he caught up on his university entrance requirements and then studied theology and social education. As a journalist in the 1970s, he looked at socially excluded groups, such as the homeless, psychiatric patients and the disabled. During this period, he collaborated with Gusti Steiner, who laid the foundation for the federal German emancipatory movement of the disabled at that time. In 1997, he received the ''Geschwister-Scholl-Preis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NSDAP
The Nazi Party, officially the National Socialist German Workers' Party (german: Nationalsozialistische Deutsche Arbeiterpartei or NSDAP), was a far-right politics, far-right political party in Germany active between 1920 and 1945 that created and supported the ideology of Nazism. Its precursor, the German Workers' Party (; DAP), existed from 1919 to 1920. The Nazi Party emerged from the Extremism, extremist German nationalism, German nationalist, racism, racist and populism, populist paramilitary culture, which fought against the communism, communist uprisings in post–World War I Germany. The party was created to draw workers away from communism and into nationalism. Initially, Nazi political strategy focused on anti–big business, anti-bourgeoisie, bourgeois, and anti-capitalism, anti-capitalist rhetoric. This was later downplayed to gain the support of business leaders, and in the 1930s, the party's main focus shifted to Antisemitism, antisemitic and Criticism of ...

Bryopsis
''Bryopsis'' is a genus of marine green algae in the family Bryopsidaceae. It is frequently a pest in aquariums, where it is commonly referred to as hair algae. Introduction ''Bryopsis''/ˌbɹaɪˈɑpsɪs/ is a genus of macroscopic, siphonous marine green algae that is made up of units of single tubular filaments. Species in this genus can form dense tufts up to 40 cm in height (Fong et al., 2019; Giovagnetti et al., 2018). Each cell is made of up an erect thallus that is often branched into pinnules (Green, 1960). Approximately 60 species have been identified in this genus since its initial discovery in 1809 (J. V. . Lamouroux, 1809). The ecological success of ''Bryopsis'' has also been attributed to its associations with endophytic bacteria that reside in the cytoplasm of their cells (Hollants, Leliaert, Verbruggen, Willems, & De Clerck, 2013). Species in this genus are known to be pests in aquariums and associated with green tides due to macroalgal blooms (Han, Li, Wei, ...

Algae
Algae (; singular alga ) is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades. Included organisms range from unicellular microalgae, such as ''Chlorella,'' ''Prototheca'' and the diatoms, to multicellular forms, such as the giant kelp, a large brown alga which may grow up to in length. Most are aquatic and autotrophic (they generate food internally) and lack many of the distinct cell and tissue types, such as stomata, xylem and phloem that are found in land plants. The largest and most complex marine algae are called seaweeds, while the most complex freshwater forms are the ''Charophyta'', a division of green algae which includes, for example, ''Spirogyra'' and stoneworts. No definition of algae is generally accepted. One definition is that algae "have chlorophyll ''a'' as their primary photosynthetic pigment and lack a sterile covering of cells around thei ...

Graft-chimaera
In horticulture, a graft-chimaera may arise in grafting at the point of contact between rootstock and scion and will have properties intermediate between those of its "parents". A graft-chimaera is not a true hybrid but a mixture of cells, each with the genotype of one of its "parents": it is a chimaera. Hence, the once widely used term "graft-hybrid" is not descriptive; it is now frowned upon. Propagation is by cloning only. In practice graft-chimaeras are not noted for their stability and may easily revert to one of the "parents". Nomenclature Article 21 of the '' ICNCP'' stipulates that a graft-chimaera can be indicated either by * a formula: the names of both "parents", in alphabetical order, joined by the plus sign "+": : ''Crataegus'' + ''Mespilus'' * a name: ** if the "parents" belong to different genera a name may be formed by joining part of one generic name to the whole of the other generic name. This name must not be identical to a generic name published under the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
