Samaná Hutia
The Samaná hutia (''Plagiodontia ipnaeum'') is an extinction, extinct species of rodent in the subfamily Hutia, Capromyinae. It was Endemism, endemic to Hispaniola (the Dominican Republic and Haiti). Its natural habitat was subtropical or tropical moist lowland forests. History The remains were found in association with those from rats of the genus ''Rattus'', which suggests that the imposter hutia survived until the time of European colonization of the island, and may have gone extinct due to predation from introduced rodents. It is possible that the Samaná hutia represents the ''quemi'', an animal purported to inhabit Hispaniola by Spanish colonist Gonzalo Fernández de Oviedo y Valdés from 1536 to 1546; it could also represent an animal called ''comadreja'', which allegedly survived into the 20th century.

Extinction
Extinction is the termination of a kind of organism or of a group of kinds (taxon), usually a species. The moment of extinction is generally considered to be the death of the last individual of the species, although the capacity to breed and recover may have been lost before this point. Because a species' potential range may be very large, determining this moment is difficult, and is usually done retrospectively. This difficulty leads to phenomena such as Lazarus taxa, where a species presumed extinct abruptly "reappears" (typically in the fossil record) after a period of apparent absence. More than 99% of all species that ever lived on Earth, amounting to over five billion species, are estimated to have died out. It is estimated that there are currently around 8.7 million species of eukaryote globally, and possibly many times more if microorganisms, like bacteria, are included. Notable extinct animal species include non-avian dinosaurs, saber-toothed cats, dodos, m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gonzalo Fernández De Oviedo Y Valdés
Gonzalo Fernández de Oviedo y Valdés (August 14781557), commonly known as Oviedo, was a Spanish soldier, historian, writer, botanist and colonist. Oviedo participated in the Spanish colonization of the West Indies, arriving in the first few years after Christopher Columbus, in 1492, became the first European to arrive at the islands. Oviedo's chronicle ''Historia general de las Indias'', published in 1535 to expand on his 1526 summary ''La Natural hystoria de las Indias'' (collectively reprinted, three centuries after his death, as ''Historia general y natural de las Indias''), forms one of the few primary sources about it. Portions of the original text were widely read in the 16th century in Spanish, English, Italian and French editions, and introduced Europeans to the hammock, the pineapple, and tobacco as well as creating influential representations of the colonized peoples of the region. Early life Oviedo was born in Madrid of an Asturian lineage and educated in the court o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammals Described In 1948
Mammals () are a group of vertebrate animals constituting the class Mammalia (), characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles (including birds) from which they diverged in the Carboniferous, over 300 million years ago. Around 6,400 extant species of mammals have been described divided into 29 orders. The largest orders, in terms of number of species, are the rodents, bats, and Eulipotyphla (hedgehogs, moles, shrews, and others). The next three are the Primates (including humans, apes, monkeys, and others), the Artiodactyla ( cetaceans and even-toed ungulates), and the Carnivora (cats, dogs, seals, and others). In terms of cladistics, which reflects evolutionary history, mammals are the only living members of the Synapsida (synapsids); this clade, together with ...

Mammals Of The Caribbean
A unique and diverse albeit phylogenetically restricted mammal fauna is known from the Caribbean region. The region—specifically, all islands in the Caribbean Sea (except for small islets close to the continental mainland) and the Bahamas, Turks and Caicos Islands, and Barbados, which are not in the Caribbean Sea but biogeographically belong to the same Caribbean bioregion—has been home to several families found nowhere else, but much of this diversity is now extinct. The bat faunas of much of the Caribbean show similarities that led to the proposal of a distinct Caribbean faunal region, bounded by "Koopman's Line". This region excludes several of the region's islands, including the Grenadines, Grenada, Trinidad, Tobago, and other islands near the American mainland, such as Margarita, Isla Escudo de Veraguas, Rosario Islands, Cozumel, and the Florida Keys. The faunas of islands outside Koopman's Line are similar to those of the adjacent mainland, though usually smaller; in con ...

Mammals Of Haiti
This is a list of the mammal species recorded in Haiti. Of the mammal species in Haiti, one is critically endangered, one is endangered, two are vulnerable, and eleven are considered to be extinct. The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature: Order: Sirenia (manatees and dugongs) ---- Sirenia is an order of fully aquatic, herbivorous mammals that inhabit rivers, estuaries, coastal marine waters, swamps, and marine wetlands. All four species are endangered. *Family: Trichechidae **Genus: ''Trichechus'' *** West Indian manatee, ''T. manatus'' presence uncertain Order: Rodentia (rodents) ---- Rodents make up the largest order of mammals, with over 40% of mammalian species. They have two incisors in the upper and lower jaw which grow continually and must be kept short by gnawing. Most rodents are small though the capybara can weigh up to . *Suborder: Hystricognathi **Family: Capr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plagiodontia
''Plagiodontia'' is a genus of rodent in the subfamily Capromyinae (hutias). All known species are endemic to the Caribbean island of Hispaniola (in the present-day Dominican Republic and Haiti). The genus name ''Plagiodontia'' means "oblique tooth", and derives from the two ancient greek words (), meaning "placed sideways", and , (), meaning "tooth". Systematics This genus contains the following three species (two of them extinct): * Hispaniolan hutia (''Plagiodontia aedium'') F. Cuvier, 1836 *† Samaná hutia The Samaná hutia (''Plagiodontia ipnaeum'') is an extinction, extinct species of rodent in the subfamily Hutia, Capromyinae.

Rattus
''Rattus'' is a genus of muroid rodents, all typically called rats. However, the term rat can also be applied to rodent species outside of this genus. Species and description The best-known ''Rattus'' species are the black rat (''R. rattus'') and the brown rat (''R. norvegicus''). The group is generally known as the Old World rats or true rats and originated in Asia. Rats are bigger than most Old World mice, which are their relatives, but seldom weigh over in the wild. Taxonomy of ''Rattus'' The genus ''Rattus'' is a member of the giant subfamily Murinae. Several other murine genera are sometimes considered part of ''Rattus'': ''Lenothrix'', ''Anonymomys'', ''Sundamys'', ''Kadarsanomys'', ''Diplothrix'', ''Margaretamys'', ''Lenomys'', ''Komodomys'', ''Palawanomys'', ''Bunomys'', ''Nesoromys'', ''Stenomys'', ''Taeromys'', ''Paruromys'', ''Abditomys'', ''Tryphomys'', ''Limnomys'', ''Tarsomys'', '' Bullimus'', ''Apomys'', ''Millardia'', '' Srilankamys'', ''Niviventer'', ''Maxomy ...

Rodent
Rodents (from Latin , 'to gnaw') are mammals of the order Rodentia (), which are characterized by a single pair of continuously growing incisors in each of the upper and lower jaws. About 40% of all mammal species are rodents. They are native to all major land masses except for New Zealand, Antarctica, and several oceanic islands, though they have subsequently been introduced to most of these land masses by human activity. Rodents are extremely diverse in their ecology and lifestyles and can be found in almost every terrestrial habitat, including human-made environments. Species can be arboreal, fossorial (burrowing), saltatorial/richochetal (leaping on their hind legs), or semiaquatic. However, all rodents share several morphological features, including having only a single upper and lower pair of ever-growing incisors. Well-known rodents include mice, rats, squirrels, prairie dogs, porcupines, beavers, guinea pigs, and hamsters. Rabbits, hares, and pikas, whose i ...
