Fernandina Island Galápagos Tortoise
''Chelonoidis niger phantasticus'' (commonly known as the Fernandina Island Galápagos tortoise or Narborough Island giant tortoise) is a subspecies of Galápagos tortoise that was discovered in 1906 and thought extinct, until a single female was discovered living on Fernandina Island by an expedition in February 2019. In May 2021, a genetic test carried out by scientists from the California Academy of Sciences confirmed that the single female tortoise discovered in 2019 is from the subspecies ''Chelonoidis niger phantasticus''. The subspecies name has often been misspelled as ''phantastica'', an error introduced in the 1980s when ''Chelonoidis'' was elevated to genus and mistakenly treated as feminine, an error recognized and fixed in 2017. Taxonomy ''Chelonoidis niger phantasticus'' is considered a subspecies of ''Chelonoidis niger'', sometimes considered a valid species itself alongside all other subspecies. Rhodin et al. (2010) lists them separately but under the heading " ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Holotype
A holotype is a single physical example (or illustration) of an organism, known to have been used when the species (or lower-ranked taxon) was formally described. It is either the single such physical example (or illustration) or one of several examples, but explicitly designated as the holotype. Under the International Code of Zoological Nomenclature (ICZN), a holotype is one of several kinds of name-bearing types. In the International Code of Nomenclature for algae, fungi, and plants (ICN) and ICZN, the definitions of types are similar in intent but not identical in terminology or underlying concept. For example, the holotype for the butterfly '' Plebejus idas longinus'' is a preserved specimen of that subspecies, held by the Museum of Comparative Zoology at Harvard University. In botany, an isotype is a duplicate of the holotype, where holotype and isotypes are often pieces from the same individual plant or samples from the same gathering. A holotype is not necessarily "typ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forrest Galante
Forrest Galante (born March 31, 1988) is an American outdoor adventurer, television personality, and conservationist. He works in the field of wildlife biology, specializing in the exploration of animals on the brink of extinction. He is the host of the television shows '' Extinct or Alive'' on Animal Planet and "Mysterious Creatures with Forrest Galante" as well as multiple Shark Week shows. Early life Shortly after his birth in California, Galante and his family moved to Harare, Zimbabwe, where his mother ran a safari business. He and his sister, named Summer, were raised on a farm that cultivated flowers and fruit, and served as a home to livestock and wild African animals. Throughout his youth, Galante spent time exploring the African bush, learning to wrangle snakes, trap small animals, and snorkel the reefs of the Bazaruto Archipelago. In Zimbabwe, he attended an English boarding school and headed up the Junior Herpetology Society, studying native flora and fauna. In 20 ...

Endemic Reptiles Of The Galápagos Islands
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Turtles Of South America
Turtles are an order of reptiles known as Testudines, characterized by a special shell developed mainly from their ribs. Modern turtles are divided into two major groups, the Pleurodira (side necked turtles) and Cryptodira (hidden necked turtles), which differ in the way the head retracts. There are 360 living and recently extinct species of turtles, including land-dwelling tortoises and freshwater terrapins. They are found on most continents, some islands and, in the case of sea turtles, much of the ocean. Like other amniotes (reptiles, birds, and mammals) they breathe air and do not lay eggs underwater, although many species live in or around water. Turtle shells are made mostly of bone; the upper part is the domed carapace, while the underside is the flatter plastron or belly-plate. Its outer surface is covered in scales made of keratin, the material of hair, horns, and claws. The carapace bones develop from ribs that grow sideways and develop into broad flat plates tha ...

Subspecies
In biological classification, subspecies is a rank below species, used for populations that live in different areas and vary in size, shape, or other physical characteristics (morphology), but that can successfully interbreed. Not all species have subspecies, but for those that do there must be at least two. Subspecies is abbreviated subsp. or ssp. and the singular and plural forms are the same ("the subspecies is" or "the subspecies are"). In zoology, under the International Code of Zoological Nomenclature, the subspecies is the only taxonomic rank below that of species that can receive a name. In botany and mycology, under the International Code of Nomenclature for algae, fungi, and plants, other infraspecific ranks, such as variety, may be named. In bacteriology and virology, under standard bacterial nomenclature and virus nomenclature, there are recommendations but not strict requirements for recognizing other important infraspecific ranks. A taxonomist decides whether ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chelonoidis
''Chelonoidis'' is a genus of turtles in the tortoise family erected by Leopold Fitzinger in 1835. They are found in South America and the Galápagos Islands, and formerly had a wide distribution in the West Indies. The multiple subspecies of the Galápagos tortoise are among the largest extant terrestrial chelonians. Giant members of the genus, such as Lutz's giant tortoise (''C. lutzae'') were also present in mainland South America and the West Indies during the Pleistocene. Taxonomy They were formerly assigned to ''Geochelone'', but a 2006 genetic analysis indicated that they were actually most closely related to hingeback tortoises. However, a more recent genetic analysis of mtDNA has found that they are actually most closely related to the lineage containing ''Centrochelys'' and ''Geochelone''. Their ancestors apparently floated across the Atlantic from Africa to South America in the Oligocene. This crossing was made possible by their ability to float with their heads u ...

Lazarus Taxon
In paleontology, a Lazarus taxon (plural ''taxa'') is a taxon that disappears for one or more periods from the fossil record, only to appear again later. Likewise in conservation biology and ecology, it can refer to species or populations that were thought to be extinct, and are rediscovered. The term Lazarus taxon was coined by Karl W. Flessa & David Jablonski in 1983 and was then expanded by Jablonski in 1986. Paul Wignall and Michael Benton defined Lazarus taxa as, "At times of biotic crisis many taxa go extinct, but others only temporarily disappeared from the fossil record, often for intervals measured in millions of years, before reappearing unchanged". Earlier work also supports the concept though without using the name Lazarus taxon, like work by Christopher R. C. Paul. The term refers to the story in the Christian biblical Gospel of John, in which Jesus Christ raised Lazarus from the dead. Potential explanations Lazarus taxa are observational artifacts that app ...

Yale University
Yale University is a private research university in New Haven, Connecticut. Established in 1701 as the Collegiate School, it is the third-oldest institution of higher education in the United States and among the most prestigious in the world. It is a member of the Ivy League. Chartered by the Connecticut Colony, the Collegiate School was established in 1701 by clergy to educate Congregational ministers before moving to New Haven in 1716. Originally restricted to theology and sacred languages, the curriculum began to incorporate humanities and sciences by the time of the American Revolution. In the 19th century, the college expanded into graduate and professional instruction, awarding the first PhD in the United States in 1861 and organizing as a university in 1887. Yale's faculty and student populations grew after 1890 with rapid expansion of the physical campus and scientific research. Yale is organized into fourteen constituent schools: the original undergraduate col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Salon (website)
''Salon'' is an American politically progressive/liberal news and opinion website created in 1995. It publishes articles on U.S. politics, culture, and current events. Content and coverage ''Salon'' covers a variety of topics, including reviews and articles about books, films, and music; articles about "modern life", including friendships, human sexual behavior, and relationships; and reviews and articles about technology, with a particular focus on the free and open-source software (FOSS) movement. According to the senior contributing writer for the ''American Journalism Review'', Paul Farhi, ''Salon'' offers "provocative (if predictably liberal) political commentary and lots of sex." In 2008, ''Salon'' launched the interactive initiative ''Open Salon'', a social content site/blog network for its readers. Originally a curated site with some of its content being featured on ''Salon'', it fell into editorial neglect and was closed in March 2015. Responding to the question ...

Santa Cruz Island (Galápagos)
Santa Cruz Island () is one of the Galápagos Islands with an area of and a maximum altitude of . Situated in the center of the archipelago, Santa Cruz is the second largest island after Isabela. Its capital is Puerto Ayora, the most populated urban centre in the islands. On Santa Cruz, there are some small villages, whose inhabitants work in agriculture and cattle raising. The island is an oval-shaped, long and wide shield volcano. Its summit contains a shallow caldera that has been largely buried by youthful pit craters and cinder cones with well-preserved craters. The most recent eruptions may have occurred only a few thousand years ago with the effusion of sparsely vegetated lava flows from vents on the north flank and along the summit fissure. A gigantic lava tube measuring over long is a tourist attraction on the island. As a testimony to its volcanic history there are two big holes formed by the collapse of a magma chamber: Los Gemelos, or "The Twins". Named after t ...

Rollo H
Rollo ( nrf, Rou, ''Rolloun''; non, Hrólfr; french: Rollon; died between 928 and 933) was a Viking who became the first ruler of Normandy, today a region in northern France. He emerged as the outstanding warrior among the Norsemen who had secured a permanent foothold on Frankish soil in the valley of the lower Seine. After the Siege of Chartres in 911, Charles the Simple, the king of West Francia, granted them lands between the mouth of the Seine and what is now Rouen in exchange for Rollo agreeing to end his brigandage, swearing allegiance to him, religious conversion and a pledge to defend the Seine's estuary from Viking raiders. The name Rollo is first recorded as the leader of these Viking settlers in a charter of 918, and he continued to reign over the region of Normandy until at least 928. He was succeeded by his son William Longsword in the Duchy of Normandy that he had founded. The offspring of Rollo and his followers, through their intermingling with the indigenous ...
