Fairy Prions
The fairy prion (''Pachyptila turtur'') is a small seabird with the standard prion (bird), prion plumage of blue-grey upperparts with a prominent dark "M" marking and white underneath. The sexes are alike. It is a small prion which frequents the low subantarctic and subtropic seas. Taxonomy The fairy prion was species description, formally described in 1820 by the German naturalist Heinrich Kuhl under the binomial name ''Procellaria turtur''. It is now placed with the other prions in the genus ''Pachyptila'', introduced in 1811 by Johann Karl Wilhelm Illiger. The genus name combines the Ancient Greek ''pakhus '', meaning "dense" or "thick", with ''ptilon'', meaning "feather" or "plumage". The specific epithet ''turtur'' is Latin for "European turtle dove, turtle dove". The word comes from the Ancient Greek word , meaning "a saw", which refers to the serrated edges of its beak, bill. The fairy prion is a member of the genus ''Pachyptila'' and of the subgenus ''Pseudoprion'' Coues ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Heinrich Kuhl
Heinrich Kuhl (17 September 1797 – 14 September 1821) was a German people, German naturalist and zoologist. Kuhl was born in Hanau (Hesse, Germany). Between 1817 and 1820, he was the assistant of professor Th. van Swinderen, docent of natural history at the University of Groningen in Groningen (the Netherlands). In 1817, he published a monograph on bats, and in 1819, he published a survey of the parrots, ''Conspectus psittacorum''. He also published the first monograph on the petrels, and a list of all the birds illustrated in Edme-Louis Daubenton, Daubenton's ''Planches Enluminées'' and with his friend Johan Coenraad van Hasselt (1797–1823) ''Beiträge zur Zoologie und vergleichenden Anatomie'' ("Contributions to Zoology and Comparative Anatomy") that were published at Frankfurt-am-Main, 1820. In 1820, he became assistant to Coenraad Jacob Temminck at the Leiden Rijksmuseum van Natuurlijke Historie. He then travelled to Java (island), Java, then part of the colonial Nethe ...

Procellariiformes
Procellariiformes is an order (biology), order of seabirds that comprises four family (biology), families: the albatrosses, the Procellariidae, petrels and shearwaters, and two families of storm petrels. Formerly called Tubinares and still called tubenoses in English, procellariiforms are often referred to collectively as the petrels, a term that has been applied to all members of the order,Warham, J. (1996). ''The Behaviour, Population, Biology and Physiology of the Petrels''. London: Academic Press, or more commonly all the families except the albatrosses.Brooke, 2004. They are almost exclusively pelagic (feeding in the open ocean), and have a cosmopolitan distribution across the world's oceans, with the highest species diversity, diversity being around New Zealand. Procellariiforms are seabird colony, colonial, mostly nesting on remote, predator-free islands. The larger species nest on the surface, while most smaller species nest in natural cavities and burrows. They exhibit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chatham Islands
The Chatham Islands ( ; Moriori language, Moriori: , 'Misty Sun'; ) are an archipelago in the Pacific Ocean about east of New Zealand's South Island, administered as part of New Zealand, and consisting of about 10 islands within an approximate radius, the largest of which are Chatham Island and Pitt Island, Pitt Island (''Rangiauria''). They include New Zealand's easternmost point, the Forty-Fours. Some of the islands, formerly cleared for farming, are now preserved as Protected areas of New Zealand, nature reserves to conservation in New Zealand, conserve some of the unique flora and fauna. The islands were uninhabited when the Moriori people arrived around 1500 CE and developed Nunuku-whenua, a peaceful way of life. In 1835, members of the Ngāti Mutunga and Ngāti Tama Māori iwi from the North Island of New Zealand invaded the islands and Moriori genocide, nearly exterminated the Moriori, slavery, enslaving the survivors. In the period of European colonisation, the New ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crozet Islands
The Crozet Islands (; or, officially, ''Archipel Crozet'') are a sub-Antarctic archipelago of small islands in the southern Indian Ocean. They form one of the five administrative districts of the French Southern and Antarctic Lands. History Discovery and early history The Crozet Islands were discovered on 24 January 1772, by the expedition of French explorer Marc-Joseph Marion du Fresne, aboard ''Le Mascarin''. His second-in-command, Julien-Marie Crozet, landed on Île de la Possession, claiming the archipelago for France. In 1776, Crozet met James Cook at Cape Town, at the start of Cook's third voyage. Crozet shared the charts of his ill-fated expedition, and as Cook sailed eastward, he stopped at the islands, naming the western group ''Marion'' and the eastern group ''Crozet''. In the following years, sealers visiting the islands referred to both the eastern and western groups as the Crozet Islands, and Marion Island became the name of the larger of the two Prince Edward ...

Bass Strait Island
Bass Strait () is a strait separating the island state of Tasmania from the Australian mainland (more specifically the coast of Victoria, with the exception of the land border across Boundary Islet). The strait provides the most direct waterway between the Great Australian Bight and the Tasman Sea, and is also the only maritime route into the economically prominent Port Phillip Bay. Formed 8,000 years ago by rising sea levels at the end of the last glacial period, the strait was named after English explorer and physician George Bass (1771–1803) by European colonists. Extent The International Hydrographic Organization defines the limits of Bass Strait as follows: :''On the west.'' The eastern limit of the Great Australian Bight Cape Otway">eing a line from Cape Otway, Australia, to King Island (Tasmania)">King Island and thence to Cape Grim, the northwest extreme of Tasmania]. :''On the east.''

Falkland Islands
The Falkland Islands (; ), commonly referred to as The Falklands, is an archipelago in the South Atlantic Ocean on the Patagonian Shelf. The principal islands are about east of South America's southern Patagonian coast and from Cape Dubouzet at the northern tip of the Antarctic Peninsula, at a latitude of about 52°S. The archipelago, with an area of , comprises East Falkland, West Falkland, and 776 smaller islands. As a British Overseas Territory, the Falklands have internal self-governance, while the United Kingdom takes responsibility for their defence and foreign affairs. The capital and largest settlement is Stanley, Falkland Islands, Stanley on East Falkland. The islands are believed to have been uninhabited prior to European discovery in the 17th century. Controversy exists over the Falklands' discovery and subsequent colonisation by Europeans. At various times, the islands have had French, British, Spanish, and Argentine settlements.

Fulmar Prion
The fulmar prion (''Pachyptila crassirostris'') is a species of seabird in the family Procellariidae, found in the southern oceans. Etymology Its common name "prion" (not to be confused with the misfolded proteins of the same name) means "saw", referring to the bill; "fulmar" means "foul-gull". The species was once assigned under the now-obsolete genus ''Fulmariprion'' (from "fulmar" and "prion"). The genus ''Pachyptila'' means "thick feathers". Its specific name ''crassirostris'' means "thick-beaked". Taxonomy The fulmar prion is a member of the genus ''Pachyptila'' – and along with the blue petrel – makes up the prions. They in turn are members of the family Procellariidae and the order Procellariiformes. The prions are small and typically eat zooplankton;Maynard, B. J. (2003) however, as a member of the Procellariiformes, they share certain identifying features. First, they have nasal passages that attach to the upper bill called naricorns, although the nostrils on t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fairy Prion Flight
A fairy (also called fay, fae, fae folk, fey, fair folk, or faerie) is a type of mythical being or legendary creature, generally described as anthropomorphic, found in the folklore of multiple European cultures (including Celtic, Slavic, Germanic, and French folklore), a form of spirit, often with metaphysical, supernatural, or preternatural qualities. Myths and stories about fairies do not have a single origin but are rather a collection of folk beliefs from disparate sources. Various folk theories about the origins of fairies include casting them as either demoted angels or demons in a Christian tradition, as deities in Pagan belief systems, as spirits of the dead, as prehistoric precursors to humans, or as spirits of nature. The label of ''fairy'' has at times applied only to specific magical creatures with human appearance, magical powers, and a penchant for trickery. At other times, it has been used to describe any magical creature, such as goblins and gnomes. ''Fa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Prion Turtur, Soland
A prion () is a misfolded protein that induces misfolding in normal variants of the same protein, leading to cellular death. Prions are responsible for prion diseases, known as transmissible spongiform encephalopathy (TSEs), which are fatal and transmissible neurodegenerative diseases affecting both humans and animals. These proteins can misfold sporadically, due to genetic mutations, or by exposure to an already misfolded protein, leading to an abnormal three-dimensional structure that can propagate misfolding in other proteins. The term ''prion'' comes from "proteinaceous infectious particle". Unlike other infectious agents such as viruses, bacteria, and fungi, prions do not contain nucleic acids (DNA or RNA). Prions are mainly twisted isoforms of the major prion protein (PrP), a naturally occurring protein with an uncertain function. They are the hypothesized cause of various TSEs, including scrapie in sheep, chronic wasting disease (CWD) in deer, bovine spongiform encep ...

Proventriculus
The proventriculus is part of the digestive system of birds.Encarta World English Dictionary orth American Edition(2007). ''Proventriculus''. Source: (accessed: December 18, 2007) An analogous organ exists in invertebrates and insects. Birds The proventriculus is a standard part of avian anatomy and is a rod-shaped organ, located between the esophagus and the gizzard of most birds. It is generally a glandular part of the stomach that may store and/or commence the digestion of food before it progresses to the gizzard. The primary function of the proventriculus is to secrete hydrochloric acid (HCl) and digestive enzymes such as pepsinogen into the digestive compartments that will churn the ingested material through muscular mechanisms. Thomas Cecere (College of Veterinary Medicine of Virginia Tech) says of the proventriculus: The proventriculus is the glandular portion of the avian compound stomach, and a rather peculiar organ it is. There's nothing like it in mammals. Sec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Triglycerides
A triglyceride (from ''wikt:tri-#Prefix, tri-'' and ''glyceride''; also TG, triacylglycerol, TAG, or triacylglyceride) is an ester derived from glycerol and three fatty acids. Triglycerides are the main constituents of body fat in humans and other vertebrates as well as vegetable fat. They are also present in the blood to enable the bidirectional transference of Adipose tissue, adipose fat and blood glucose from the liver and are a major component of sebum, human skin oils. Many types of triglycerides exist. One specific classification focuses on Saturated and unsaturated compounds, saturated and unsaturated types. Saturated fats have ''no'' C=C groups; unsaturated fats feature one or more C=C groups. Unsaturated fats tend to have a lower melting point than saturated analogues; as a result, they are often liquid at room temperature. Chemical structure The three fatty acids substituents can be the same, but they are usually different. The positions of the three fatty acids a ...
