Procerithiidae
Procerithiidae is a taxonomic family of sea snails, marine gastropod molluscs in the clade Sorbeoconcha. ''Argyropeza'' is the only extant genus in the Procerithiidae. Taxonomy The following three subfamilies are recognized in the taxonomy of Bouchet & Rocroi (2005): * † Procerithiinae Cossmann, 1906 * † Paracerithiinae Cossmann, 1906 * Cryptaulacinae Gründel, 1976 - include ''Argyropeza'' 2006 taxonomy Bandel (2006)Bandel K.

Argyropeza
''Argyropeza'' is a genus of small deep-sea sea snails, marine gastropod molluscs in the family Procerithiidae.WoRMS (2010). ''Argyropeza'' Melvill & Standen, 1901. In: Bouchet, P.; Gofas, S.; Rosenberg, G. (2010) World Marine Mollusca database. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=473011 on 2010-05-12 The name of this genus is derived from the Greek word ''arguropeza'' ("silver foot"), the epithet given by Homer to the sea nymph Thetis. Taxonomy The genus ''Argyropeza'' is closely related to the genus'' Bittium'', but the shells of species in this genus are thinner and more vitreous, and the suture is more deeply impressed. This genus is not well known and its systematic position has long been uncertain. It was sometimes assigned to the Litiopidae Gray, 1847 or to the Cerithiinae within Cerithiidae,Houbrick R. S. (1980) "Review of the deep-sea genus ''Argyropeza'' (Gastropoda: Prosobranchia: Cerithi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cerithioidea
The Cerithioidea is a superfamily of marine, brackish water and freshwater gastropod containing more than 200 genera. The Cerithoidea are included unassigned in the subclass Caenogastropoda. The original name of this superfamily was Cerithiacea, in keeping with common superfamily endings at the time. Ecology Cerithioidea is a very diverse superfamily. Its species can be found worldwide mainly in tropic and subtropic seas on rocky intertidal shores, seagrass beds and algal fronds, but also in estuarine and freshwater habitats. The freshwater species are found on all continents, except Antarctica. They are dominant members of mangrove forests, estuarine mudflats, fast-flowing rivers and placid lakes.Healy J. M. & Wells F.

Taxonomy Of The Gastropoda (Bouchet & Rocroi, 2005)
The taxonomy of the Gastropoda as it was revised in 2005 by Philippe Bouchet and Jean-Pierre Rocroi is a system for the scientific classification of gastropod mollusks. (Gastropods are a taxonomic class of animals which consists of snails and slugs of every kind, from the land, from freshwater, and from saltwater.) The paper setting out this taxonomy was published in the journal ''Malacologia''. The system encompasses both living and extinct groups, as well as some fossils whose classification as gastropods is uncertain. The Bouchet & Rocroi system was the first complete gastropod taxonomy that primarily employed the concept of clades, and was derived from research on molecular phylogenetics; in this context a clade is a "natural grouping" of organisms based upon a statistical cluster analysis. In contrast, most of the previous overall taxonomic schemes for gastropods relied on morphological features to classify these animals, and used taxon ranks such as order, superorder ...

Extant Taxon
Neontology is a part of biology that, in contrast to paleontology, deals with living (or, more generally, '' recent'') organisms. It is the study of extant taxa (singular: extant taxon): taxa (such as species, genera and families) with members still alive, as opposed to (all) being extinct. For example: * The moose (''Alces alces'') is an extant species, and the dodo (''Raphus cucullatus'') is an extinct species. * In the group of molluscs known as the cephalopods, there were approximately 600 extant species and 7,500 extinct species. A taxon can be classified as extinct if it is broadly agreed or certified that no members of the group are still alive. Conversely, an extinct taxon can be reclassified as extant if there are new discoveries of living species ("Lazarus species"), or if previously-known extant species are reclassified as members of the taxon. Most biologists, zoologists, and botanists are in practice neontologists, and the term neontologist is used large ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Freiberger Forschungshefte
The Freiberger, also known as Franches-Montagnes, is a horse breed from Switzerland, from the Jura region, described as either a "heavy warmblood" or a "light coldblood". It was widely used as draft and pack horse in the Swiss army. It has a good disposition and is versatile, suitable for both driving and riding. Each year at the ''Marché Concours'' in Saignelégier in the Franches-Montagnes district of the Swiss canton of Jura, on the second weekend in August, a variety of shows and competitions are held. Breed characteristics History The presence of an autochthonous horse breed in the Jura traces to the year 1619. By the early 19th century, there were active breeders in the district of Franches-Montagnes. In 1817, there were 4,000 breeding mares on record. The horses were bred for use in agriculture and by the army as pack animals and artillery draft horses. There are records of imports of Anglo-Norman horses for the year 1821, and of other horses from England, Fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
