William Charles Linnaeus Martin
William Charles Linnaeus Martin (1798–1864) was an English naturalist. Biography William Charles Linnaeus Martin was the son of William Martin (naturalist) and his wife, Mary. William Martin had published early colour books on the fossils of Derbyshire, and named his son Linnaeus in honour of his interest in the classification of living things. Martin was the curator of the museum of the Zoological Society of London from 1830 to 1838, when he lost his appointment due to financial cutbacks. He then became a freelance natural history writer, publishing over a thousand articles and books, including ''A Natural History of Quadrupeds and other Mammiferous Animals'' (1841), ''The History of the Dog'' (1845), ''The History of the Horse'' (1845), and ''Pictorial Museum of Animated Nature'' (1848-9). Many of Martin's works centred around the study of farm animals, particularly in the years 1847-1858.Woodward, B. B., and Yolanda Foote. "Martin, William Charles Linnaeus (1798–186 ...

South America
South America is a continent entirely in the Western Hemisphere and mostly in the Southern Hemisphere, with a relatively small portion in the Northern Hemisphere at the northern tip of the continent. It can also be described as the southern subregion of a single continent called America. South America is bordered on the west by the Pacific Ocean and on the north and east by the Atlantic Ocean; North America and the Caribbean Sea lie to the northwest. The continent generally includes twelve sovereign states: Argentina, Bolivia, Brazil, Chile, Colombia, Ecuador, Guyana, Paraguay, Peru, Suriname, Uruguay, and Venezuela; two dependent territories: the Falkland Islands and South Georgia and the South Sandwich Islands; and one internal territory: French Guiana. In addition, the ABC islands of the Kingdom of the Netherlands, Ascension Island (dependency of Saint Helena, Ascension and Tristan da Cunha, a British Overseas Territory), Bouvet Island ( dependency ...

Reptile
Reptiles, as most commonly defined are the animals in the class Reptilia ( ), a paraphyletic grouping comprising all sauropsids except birds. Living reptiles comprise turtles, crocodilians, squamates ( lizards and snakes) and rhynchocephalians ( tuatara). As of March 2022, the Reptile Database includes about 11,700 species. In the traditional Linnaean classification system, birds are considered a separate class to reptiles. However, crocodilians are more closely related to birds than they are to other living reptiles, and so modern cladistic classification systems include birds within Reptilia, redefining the term as a clade. Other cladistic definitions abandon the term reptile altogether in favor of the clade Sauropsida, which refers to all amniotes more closely related to modern reptiles than to mammals. The study of the traditional reptile orders, historically combined with that of modern amphibians, is called herpetology. The earliest known proto-reptiles originated ...

Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing a faunal interchange between the two reg ...

Pseudalopex Fulvipes-primer Plano
The South American foxes (''Lycalopex''), commonly called ''raposa'' in Portuguese, or ''zorro'' in Spanish, are a genus from South America of the subfamily Caninae. Despite their name, they are not true foxes, but are a unique canid genus more closely related to wolves and jackals than to true foxes; some of them resemble foxes due to convergent evolution. The South American gray fox, ''Lycalopex griseus'', is the most common species, and is known for its large ears and a highly marketable, russet-fringed pelt. The second-oldest known fossils belonging to the genus were discovered in Chile, and date from 2.0 to 2.5 million years ago, in the mid- to late Pliocene. The Vorohué Formation of Argentina has provided older fossils, dating to the Uquian to Ensenadan (Late Pliocene).Vorohuen ...

Lycalopex Griseus
The South American gray fox (''Lycalopex griseus''), also known as the Patagonian fox, the chilla or the gray zorro, is a species of ''Lycalopex'', the "false" foxes. It is endemic to the southern part of South America. Description The South American gray fox is a small fox-like canid, weighing , and measuring in length including a tail of . The head is reddish-brown flecked with white. The ears are large and there is a distinct black spot on the chin. The pelage is brindled, with agouti guard hairs and a short, dense pale undercoat. The underparts are pale grey. The limbs are tawny and the thighs are crossed by a dark bar. The long, bushy tail has a dark dorsal stripe and dark tip with a paler, mottled underside. Range and habitat The South American gray fox is found in the Southern Cone of South America, particularly in Argentina and Chile. Its range comprises a stripe, both sides of the Andes Mountain Range between parallels 17ºS (northernmost Chile) and 54ºS (Tierra del ...

Sechuran Fox
The Sechuran fox (''Lycalopex sechurae''), also called the Peruvian desert fox or the Sechuran zorro, is a small South American species of canid closely related to other South American "false" foxes or zorro. It gets its name for being found in the Sechura Desert in northwestern Peru. It is one of ten extant species of canid endemic to South America. This fox inhabits a narrow region west of the Andes Mountains running along the coastline of Peru and southern Ecuador. More specifically, in dry areas such as savannah-like deserts, cliff-sides, along the western side of the Andes mountains, and beaches. The Sechuran Fox is known by the common names Sechura desert fox and Peruvian desert fox. The etymology of its scientific name comes from the Greek "lycos" meaning "wolf," and "alopex" meaning "fox". Before it was classified under ''Lycalopex'', the Sechuran fox was classed under the ''Dusicyon'' genus established by Oldfield Thomas in 1914, and was later moved to the ''Pseudalope ...

Hybrid (biology)
In biology, a hybrid is the offspring resulting from combining the qualities of two organisms of different breeds, varieties, species or genera through sexual reproduction. Hybrids are not always intermediates between their parents (such as in blending inheritance), but can show hybrid vigor, sometimes growing larger or taller than either parent. The concept of a hybrid is interpreted differently in animal and plant breeding, where there is interest in the individual parentage. In genetics, attention is focused on the numbers of chromosomes. In taxonomy, a key question is how closely related the parent species are. Species are reproductively isolated by strong barriers to hybridisation, which include genetic and morphological differences, differing times of fertility, mating behaviors and cues, and physiological rejection of sperm cells or the developing embryo. Some act before fertilization and others after it. Similar barriers exist in plants, with differences in flowering t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Accessed July 10, 2021 at https://lib.dr.iastate.edu/cgi/viewcontent.cgi?article=11006&context=rtd and colpeo fox, is a species of South American fox. Regardless of the name, it is not a true fox, but more closely related to wolves and jackals. Its appearance resembles that of foxes due to convergent evolution. It is the second-largest native canid on the continent after the maned wolf. In appearance, it bears many similarities to the widely recognized red fox. It has grey and reddish fur, a white chin, reddish legs and a stripe on its back that may be barely visible. The culpeo's diet consists largely of rodents, rabbits, birds and lizards, and to a lesser extent, plant material and carrion. The culpeo do ...

The Voyage Of The Beagle
''The Voyage of the Beagle'' is the title most commonly given to the book written by Charles Darwin and published in 1839 as his ''Journal and Remarks'', bringing him considerable fame and respect. This was the third volume of ''The Narrative of the Voyages of H.M. Ships Adventure and Beagle'', the other volumes of which were written or edited by the commanders of the ships. ''Journal and Remarks'' covers Darwin's part in the second survey expedition of the ship HMS ''Beagle''. Due to the popularity of Darwin's account, the publisher reissued it later in 1839 as Darwin's ''Journal of Researches'', and the revised second edition published in 1845 used this title. A republication of the book in 1905 introduced the title ''The Voyage of the "Beagle"'', by which it is now best known. ''Beagle'' sailed from Plymouth Sound on 27 December 1831 under the command of Captain Robert FitzRoy. While the expedition was originally planned to last two years, it lasted almost five—''Beagle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
