Adamussium
''Adamussium'' is a genus of scallops belonging to the family Pectenidae from the Southern Ocean around Antarctica. There are three known species but only one is extant, the Antarctic scallop (''A. colbecki''). Of the two extinct species ''A. jonkersi'' is from the Oligocene deposits on King George Island in the South Shetland Islands and the other, ''A. necopinatum'', was described in 2016 from Pliocene marine deposits in the Vestfold Hills of East Antarctica. Species The following species are classified within the genus ''Adamussium'': * ''Adamussium colbecki'' ( E. A. Smith, 1902) (Antarctic scallop) * ''Adamussium jonkersi'' Quaglio, Whittle, Gaździcki & Simoes, 2010 * ''Adamussium necopinatum'' Quilty, Darragh, Gallagher & Harding Harding may refer to: People *Harding (surname) *Maureen Harding Clark (born 1946), Irish jurist Places Australia * Harding River Iran * Harding, Iran, a village in South Khorasan Province South Africa * Harding, KwaZulu-Natal Unit ...

Adamussium Colbecki
The Antarctic scallop (''Adamussium colbecki'') is a species of bivalve mollusc in the large family of scallops, the Pectinidae. It was thought to be the only species in the genus ''Adamussium'' until an extinct Pliocene species was described in 2016. Its exact relationship to other members of the Pectinidae is unclear. It is found in the ice-cold seas surrounding Antarctica, sometimes at great depths. ''Adamussium colbecki'' is a large, slow-growing scallop that lives on the seabed. The shell consists of a pair of ribbed calcareous valves which enclose the soft body and are joined by a ligament at a hinge. It feeds on microscopic green algae and is sometimes present in great numbers. It is able to move around by flapping its valves and to dart backwards to escape threats. The species is an important member of the Antarctic seabed community as the upper valve often acts as a substrate for seaweeds, sponges and other organisms. In addition, juveniles bind themselves by threads t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pectinidae
Scallop () is a common name that encompasses various species of marine bivalve mollusks in the taxonomic family Pectinidae, the scallops. However, the common name "scallop" is also sometimes applied to species in other closely related families within the superfamily Pectinoidea, which also includes the thorny oysters. Scallops are a cosmopolitan family of bivalves found in all of the world's oceans, although never in fresh water. They are one of the very few groups of bivalves to be primarily "free-living", with many species capable of rapidly swimming short distances and even migrating some distance across the ocean floor. A small minority of scallop species live cemented to rocky substrates as adults, while others attach themselves to stationary or rooted objects such as seagrass at some point in their lives by means of a filament they secrete called a byssal thread. The majority of species, however, live recumbent on sandy substrates, and when they sense the presence of a pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Southern Ocean
The Southern Ocean, also known as the Antarctic Ocean, comprises the southernmost waters of the World Ocean, generally taken to be south of 60° S latitude and encircling Antarctica. With a size of , it is regarded as the second-smallest of the five principal oceanic divisions: smaller than the Pacific, Atlantic, and Indian oceans but larger than the Arctic Ocean. Over the past 30 years, the Southern Ocean has been subject to rapid climate change, which has led to changes in the marine ecosystem. By way of his voyages in the 1770s, James Cook proved that waters encompassed the southern latitudes of the globe. Since then, geographers have disagreed on the Southern Ocean's northern boundary or even existence, considering the waters as various parts of the Pacific, Atlantic, and Indian oceans, instead. However, according to Commodore John Leech of the International Hydrographic Organization (IHO), recent oceanographic research has discovered the importance of Southern ...

Johannes Thiele (zoologist)
Karl Hermann Johannes Thiele (1 October 1860 – 5 August 1935) was a German zoologist specialized in malacology. Thiele was born in Goldap, East Prussia. His ''Handbuch der systematischen Weichtierkunde'' (English edition published by the Smithsonian under the title ''Handbook of Systematic Malacology'') is a standard work. From 1904 until his retirement in 1925 he was the curator of the malacological collection at the Museum für Naturkunde (Museum of Natural History) in Berlin. Thiele described more than 1.500 new species of molluscs; until today their types are deposited with the Museum of Natural History in Berlin. Especially important are his works on the Mollusca of the First German Antarctica Expedition and of the German Deep Sea Expedition aboard the vessel Valdivia. Thiele's classification of Gastropoda has been in use up to the past decade. It modified an earlier concept of Henri Milne-Edwards (1848) with three subclasses: Prosobranchia, Opisthobranchia and Pulmonata. ...

Rowan J
The rowans ( or ) or mountain-ashes are shrubs or trees in the genus ''Sorbus'' of the rose family, Rosaceae. They are native throughout the cool temperate regions of the Northern Hemisphere, with the highest species diversity in the Himalaya, southern Tibet and parts of western China, where numerous apomictic microspecies occur.Rushforth, K. (1999). ''Trees of Britain and Europe''. Collins . The name ''rowan'' was originally applied to the species ''Sorbus aucuparia'' and is also used for other species in ''Sorbus'' subgenus ''Sorbus''. Formerly, when a wider variety of fruits were commonly eaten in Europe and North America, ''Sorbus'' was a domestically used fruit throughout these regions. It is still used in some countries, but '' S. domestica'', for example, has largely vanished from Britain, where it was traditionally appreciated. Natural hybrids, often including ''S. aucuparia'' and the whitebeam, ''Sorbus aria'', give rise to many endemic variants in the UK. ...

Lucy A
Lucy is an English feminine given name derived from the Latin masculine given name Lucius with the meaning ''as of light'' (''born at dawn or daylight'', maybe also ''shiny'', or ''of light complexion''). Alternative spellings are Luci, Luce, Lucie, Lucia, and Luzia. The English Lucy surname is taken from the Norman language that was Latin-based and derives from place names in Normandy based on Latin male personal name Lucius. It was transmitted to England after the Norman Conquest in the 11th century (see also De Lucy).

Stephen J
Stephen or Steven is a common English first name. It is particularly significant to Christians, as it belonged to Saint Stephen ( grc-gre, Στέφανος ), an early disciple and deacon who, according to the Book of Acts, was stoned to death; he is widely regarded as the first martyr (or "protomartyr") of the Christian Church. In English, Stephen is most commonly pronounced as ' (). The name, in both the forms Stephen and Steven, is often shortened to Steve or Stevie. The spelling as Stephen can also be pronounced which is from the Greek original version, Stephanos. In English, the female version of the name is Stephanie. Many surnames are derived from the first name, including Stephens, Stevens, Stephenson, and Stevenson, all of which mean "Stephen's (son)". In modern times the name has sometimes been given with intentionally non-standard spelling, such as Stevan or Stevon. A common variant of the name used in English is Stephan ; related names that have found some c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
