Gottschelia
''Gottschelia'' is a genus of liverworts belonging to the family Cephaloziellaceae. The genus has cosmopolitan distribution. The genus name of ''Gottschelia'' is in honour of Carl Moritz Gottsche (1808–1892), who was a German physician and bryologist born in Altona. The genus was circumscribed In geometry, the circumscribed circle or circumcircle of a polygon is a circle that passes through all the vertices of the polygon.

Carl Moritz Gottsche
Carl Moritz Gottsche (3 July 1808 – 28 September 1892) was a German physician and bryologist born in Altona. He was the father of geologist Carl Christian Gottsche (1859-1909). Gottsche was a leading authority of Hepaticae. With Christian Gottfried Daniel Nees von Esenbeck (1776-1858) and Johann Bernhard Wilhelm Lindenberg (1781-1851), he was author of ''Synopsis Hepaticarum'' (1844-47), which was a landmark work in the field of hepaticology. In 1881 he received an honorary doctorate in philosophy from the University of Kiel. The botanical genera of liverworts; ''Gottschea'' in the family Schistochilaceae is named after him, as well as ''Gottschelia'', which is in the family Cephaloziellaceae Cephaloziellaceae is a family of liverworts belonging to the order Jungermanniales.

Liverwort
The Marchantiophyta () are a division of non-vascular land plants commonly referred to as hepatics or liverworts. Like mosses and hornworts, they have a gametophyte-dominant life cycle, in which cells of the plant carry only a single set of genetic information. It is estimated that there are about 9000 species of liverworts. Some of the more familiar species grow as a flattened leafless thallus, but most species are leafy with a form very much like a flattened moss. Leafy species can be distinguished from the apparently similar mosses on the basis of a number of features, including their single-celled rhizoids. Leafy liverworts also differ from most (but not all) mosses in that their leaves never have a costa (present in many mosses) and may bear marginal cilia (very rare in mosses). Other differences are not universal for all mosses and liverworts, but the occurrence of leaves arranged in three ranks, the presence of deep lobes or segmented leaves, or a lack of clearly di ...

Cosmopolitan Distribution
In biogeography, cosmopolitan distribution is the term for the range of a taxon that extends across all or most of the world in appropriate habitats. Such a taxon, usually a species, is said to exhibit cosmopolitanism or cosmopolitism. The extreme opposite of a cosmopolitan species is an endemic one, being found only in a single geographical location. Qualification The caveat “in appropriate habitat” is used to qualify the term "cosmopolitan distribution", excluding in most instances polar regions, extreme altitudes, oceans, deserts, or small, isolated islands. For example, the housefly is highly cosmopolitan, yet is neither oceanic nor polar in its distribution. Related terms and concepts The term pandemism also is in use, but not all authors are consistent in the sense in which they use the term; some speak of pandemism mainly in referring to diseases and pandemics, and some as a term intermediate between endemism and cosmopolitanism, in effect regarding pandemism as ...

Bryology
Bryology (from Greek , a moss, a liverwort) is the branch of botany concerned with the scientific study of bryophytes (mosses, liverworts, and hornworts). Bryologists are people who have an active interest in observing, recording, classifying or researching bryophytes. The field is often studied along with lichenology due to the similar appearance and ecological niche of the two organisms, even though bryophytes and lichens are not classified in the same kingdom. History Bryophytes were first studied in detail in the 18th century. The German botanist Johann Jacob Dillenius (1687–1747) was a professor at Oxford and in 1717 produced the work "Reproduction of the ferns and mosses." The beginning of bryology really belongs to the work of Johannes Hedwig, who clarified the reproductive system of mosses (1792, ''Fundamentum historiae naturalist muscorum'') and arranged a taxonomy. Research Areas of research include bryophyte taxonomy, bryophytes as bioindicators, DNA s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Altona, Hamburg
Altona (), also called Hamburg-Altona, is the westernmost urban borough (''Bezirk'') of the German city state of Hamburg, on the right bank of the Elbe river. From 1640 to 1864, Altona was under the administration of the Danish monarchy. Altona was an independent borough until 1937. In 2016 the population was 270,263. History Altona was founded in 1535 as a village of fishermen in what was then Holstein-Pinneberg. In 1640, Altona came under Danish rule as part of Holstein-Glückstadt, and in 1664 was granted municipal rights by the Danish King Frederik III, who then ruled in personal union as Duke of Holstein. Altona was one of the Danish monarchy's most important harbor towns. The railroad from Altona to Kiel, the Hamburg-Altona–Kiel railway ( da, link=no, Christian VIII Østersø Jernbane), was opened in 1844. Because of severe restrictions on the number of Jews allowed to live in Hamburg until 1864 (with the exception of 1811–1815), a major Jewish communi ...

Circumscription (taxonomy)
In biological taxonomy, circumscription is the content of a taxon, that is, the delimitation of which subordinate taxa are parts of that taxon. If we determine that species X, Y, and Z belong in Genus A, and species T, U, V, and W belong in Genus B, those are our circumscriptions of those two genera. Another systematist might determine that T, U, V, W, X, Y, and Z all belong in genus A. Agreement on circumscriptions is not governed by the Codes of Zoological or Botanical Nomenclature, and must be reached by scientific consensus. A goal of biological taxonomy is to achieve a stable circumscription for every taxon. This goal conflicts, at times, with the goal of achieving a natural classification that reflects the evolutionary history of divergence of groups of organisms. Balancing these two goals is a work in progress, and the circumscriptions of many taxa that had been regarded as stable for decades are in upheaval in the light of rapid developments in molecular phylogene ...

Jungermanniales
Jungermanniales is the largest order of liverworts. They are distinctive among the liverworts for having thin leaf-like flaps on either side of the stem. Most other liverworts are thalloid, with no leaves. Due to their dorsiventral organization and scale-like, overlapping leaves, the Jungermanniales are sometimes called "scale-mosses".
