Malacologist
Malacology is the branch of invertebrate zoology that deals with the study of the Mollusca (mollusks or molluscs), the second-largest phylum of animals in terms of described species after the arthropods. Mollusks include snails and slugs, clams, and cephalopods, along with numerous other kinds, many of which have shells. One division of malacology, conchology, is devoted to the study of mollusk shells. Malacology derives . Fields within malacological research include taxonomy, ecology Ecology () is the study of the relationships between living organisms, including humans, and their physical environment. Ecology considers organisms at the individual, population, community, ecosystem, and biosphere level. Ecology overlaps wi ... and evolution. Applied malacology studies medical, veterinary, and agricultural applications; for example, mollusks as vectors of disease, as in schistosomiasis. Archaeology employs malacology to understand the evolution of the climate, the biota ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malakozoologische Blätter
Malakozoologische Blätter was a German-language journal for malacology. It was published from 1854 to 1891 as a continuation of ''Zeitschrift für Malakozoologie'' (which was published 1844–1853). Karl Theodor Menke and Ludwig Karl Georg Pfeiffer were joint co-editors-in-chief, until Menke's death in 1861 after which Pfeiffer became sole editor-in-chief. Upon Pfeiffers's death in 1877, Stefan Clessin became sole editor-in-chief and continued in that capacity until cessation of publication with the last volume in 1891. The volumes from 1854 through 1878 were numbered from 1 to 25. The volumes from 1879 through 1891 were numbered in a new series (''Neue Folge'') from 1 through 11 with volumes 3 and 4 both for the year 1881 (so that volume 1 was in 1879 and volume 5 was in 1882). The journal was published by T.

Würzburg
Würzburg (; Main-Franconian: ) is a city in the region of Franconia in the north of the German state of Bavaria. Würzburg is the administrative seat of the ''Regierungsbezirk'' Lower Franconia. It spans the banks of the Main River. Würzburg is situated approximately east-southeast of Frankfurt am Main and approximately west-northwest of Nuremberg (). The population (as of 2019) is approximately 130,000 residents. The administration of the ''Landkreis Würzburg'' ( district of Würzburg) is also located in the town.

Regensburg
Regensburg or is a city in eastern Bavaria, at the confluence of the Danube, Naab and Regen rivers. It is capital of the Upper Palatinate subregion of the state in the south of Germany. With more than 150,000 inhabitants, Regensburg is the fourth-largest city in the State of Bavaria after Munich, Nuremberg and Augsburg. From its foundation as an imperial Roman river fort, the city has been the political, economic and cultural centre of the surrounding region; it is still known in the Romance languages by a cognate of its Latin name of "Ratisbona" (the version "Ratisbon" was long current in English). Later, under the rule of the Holy Roman Empire, it housed the Perpetual Diet of Regensburg. The medieval centre of the city was made a UNESCO World Heritage Site in 2006 because of its well-preserved architecture and the city's historical importance for assemblies during the Holy Roman Empire. In 2014, Regensburg was among the top sights and travel attractions in Germany. Histor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Friedrich Heinrich Wilhelm Martini
Friedrich Heinrich Wilhelm Martini (31 August 1729,Ohrdruf – 27 June 1778, Berlin) was a German physician, translator and conchologist. Martini who practised medicine in Hamburg began, in 1769, the richly colour illustrated shell book: ''Neues systematisches Conchylien-Cabinet'' published by Gabriel Nikolaus Raspe at Nürnberg. But he died after the publication of the third volume. His work was continued by Johann Hieronymus Chemnitz (1730–1800) who added eight volumes between 1779 and 1795. Even though the work does not use the binomial system both are considered the authors of the new species figured. Stanley Peter Dance (1966). ''Shell Collecting. An Illustrated History''.

Johann Hieronymus Chemnitz
Johann Hieronymus Chemnitz (10 October 1730, Magdeburg – 12 October 1800, Copenhagen) was a German clergyman and a conchologist. From 1759 to 1768 he was Chaplain of the Danish Embassy in Vienna, then garrison Chaplain in Helsingør and Copenhagen. Johann Chemnitz continued the work of Friedrich Wilhelm Martini (1729–1778), ''Neues systematisches Conchylien-Cabinet''. He added to the three volumes previously published eight new volumes in 1779 and 1795. Although neither of the two authors use the binomial system, they are regarded as the authors of many species which were first described in this work. Chemnitz used many specimens from cabinet of curiosities of the king of Denmark whose conservator was Lorenz Spengler (1720–1807). Chemnitz began with a collection of half shells before collecting whole shells. His patron was Christian Hee Hwass (1731–1803). The 5th volume describes and portrays many shells from New Zealand and some from Australia collected during Cook ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rudolf Vierhaus
Rudolf Vierhaus (29 October 1922 – 13 November 2011) was a German historian who mainly researched the Early modern period. He had been a professor at the newly founded Ruhr University Bochum since 1964. From 1971, he was director of the in Göttingen. He became known for his research on the Age of Enlightenment. Life Born in Wanne-Eickel, the son of a coalminer was the first of his family to attend the Oberrealschule and passed his Abitur in 1941. In the same year, he was called up for military service. As a lieutenant, he was seriously wounded in the battle with American troops at the Moselle in autumn 1944. Vierhaus was captured in Marburg the following year. He spent the following years in military hospitals and clinics. It was not until 1949 that his state of health was reasonably restored. From 1949 he studied history and philosophy at the Westfälische Wilhelms-Universität . His academic teachers were Kurt von Raumer, Herbert Grundmann and Joachim Ritter. Vierhaus w ...

Gastropod
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species. The anatomy, behavior, feeding, and re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mollusk
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.
