List Of Adaptive Radiated Marsupials By Form
This is a list of adaptive radiated marsupials by form; they are adaptively radiated marsupial species equivalent to the many niche-types of non-marsupial mammals. Many of the surviving species are from Australia. There are unique types, for example the extinct genus ''Nototherium'', a 'rhinoceros-type'. The new world has the common opossum, also a unique form.Wilson, Eisner, Briggs, Dickerson, Metzenberg, O'Brien, Susman, & Boggs. ''Life on Earth'', Chapter: Biogeography, Graphic: Adaptive Radiation of Marsupials, p. 854-855. Even before the mid-19th century and Charles Darwin's time, biogeographers understood speciation and animal niches. A supreme example that became known to Darwin as sailing ships traveled the world is the New Zealand flightless, ground-dwelling, worm-eating kiwi, a bird, but a species in a mammal-niche.

Marsupial
Marsupials are any members of the mammalian infraclass Marsupialia. All extant marsupials are endemic to Australasia, Wallacea and the Americas. A distinctive characteristic common to most of these species is that the young are carried in a pouch. Marsupials include opossums, Tasmanian devils, kangaroos, koalas, wombats, wallabies, bandicoots, and the extinct thylacine. Marsupials represent the clade originating from the last common ancestor of extant metatherians, the group containing all mammals more closely related to marsupials than to placentals. They give birth to relatively undeveloped young that often reside in a pouch located on their mothers' abdomen for a certain amount of time. Close to 70% of the 334 extant species occur on the Australian continent (the mainland, Tasmania, New Guinea and nearby islands). The remaining 30% are found in the Americas—primarily in South America, thirteen in Central America, and one species, the Virginia opossum, in Nort ...

Numbat
The numbat (''Myrmecobius fasciatus''), also known as the noombat or walpurti, is an insectivorous marsupial. It is diurnal and its diet consists almost exclusively of termites. The species was once widespread across southern Australia, but is now restricted to several small colonies in Western Australia. It is therefore considered an endangered species and protected by conservation programs. Numbats were recently re-introduced to fenced reserves in South Australia and New South Wales. The numbat is the faunal emblem of Western Australia. Taxonomy The numbat genus ''Myrmecobius'' is the sole member of the family Myrmecobiidae, one of four families that make up the order Dasyuromorphia, the Australian marsupial carnivores. The species is not closely related to other extant marsupials; the current arrangement in the order Dasyuromorphia places its monotypic family with the diverse and carnivorous species of Dasyuridae. Genetic studies have shown the ancestors of the numb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Groundhog
The groundhog (''Marmota monax''), also known as a woodchuck, is a rodent of the family Sciuridae, belonging to the group of large ground squirrels known as marmots. The groundhog is a lowland creature of North America; it is found through much of the Eastern United States, across Canada and into Alaska. It was first scientifically described by Carl Linnaeus in 1758. The groundhog is also referred to as a chuck, wood-shock, groundpig, whistlepig, whistler, thickwood badger, Canada marmot, monax, moonack, weenusk, red monk, land beaver, and, among French Canadians in eastern Canada, siffleux. The name "thickwood badger" was given in the Northwest to distinguish the animal from the prairie badger. Monax (''Móonack'') is an Algonquian name of the woodchuck, which means "digger" (cf. Lenape ''monachgeu''). Young groundhogs may be called chucklings. The groundhog, being a lowland animal, is exceptional among marmots. Other marmots, such as the yellow-bellied and hoary marmots ...

Dasyurus Viverrinus
The eastern quoll (''Dasyurus viverrinus'', formerly known as the eastern native cat) is a medium-sized carnivorous marsupial (dasyurid), and one of six extant species of quolls. Endemic to Australia, they occur on the island state of Tasmania, but were considered extinct on the mainland after 1963. The species has been reintroduced to fox-proof fenced sanctuaries Victoria in 2003 and to the Australian Capital Territory in 2016. Taxonomy The eastern quoll is a member of the family Dasyuridae, which includes most carnivorous marsupials. Its species name, ''viverrinus'', indicates it is "ferret-like". There are no recognised subspecies. Description Eastern quolls are about the size of a small domestic cat, with adult males measuring in total length, including the tail, and having an average weight of . Females are significantly smaller, measuring , including a tail, and weighing around . They have a tapering snout, short legs, and erect ears. They can be distinguished ...

Dasyurus Spartacus
The bronze quoll (''Dasyurus spartacus'') is a species of quoll found only in the Trans-Fly savanna and grasslands of New Guinea and West Papua. History It was discovered in the early 1970s when five specimens were collected, but only described in 1987 when Dr. Stephen Van Dyck of the Queensland Museum examined them and recognised their distinctness. there are twelve public museum specimens, 8 from traps and 4 from local hunters. It is the largest surviving marsupial carnivore of New Guinea, after the thylacine's extirpation from New Guinea thousands of years ago. Taxonomy Very little is known of it; it was previously thought to be an outlying population of the western quoll (''Dasyurus geoffroii''). Status , there was an estimated population of less than 10,000 and was listed as Near Threatened on the IUCN Red List. A nocturnal predator, it inhabits savanna woodlands. It is threatened by introduced predators like domesticated and feral dogs, and feral cats. It has been obser ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dasyurus Maculatus
The tiger quoll (''Dasyurus maculatus''), also known as the spotted-tail quoll, the spotted quoll, the spotted-tail dasyure, native cat or the tiger cat, is a carnivorous marsupial of the quoll genus '' Dasyurus'' native to Australia. With males and females weighing around , respectively, it is the world's second-largest extant carnivorous marsupial, behind the Tasmanian devil. Two subspecies are recognised; the nominate is found in wet forests of southeastern Australia and Tasmania, and a northern subspecies, ''D. m. gracilis'', is found in a small area of northern Queensland and is endangered. Taxonomy The tiger quoll is a member of the family Dasyuridae, which includes most carnivorous marsupial mammals. This quoll was first described in 1792 by Robert Kerr, the Scottish writer and naturalist, who placed it in the genus '' Didelphis'', which includes several species of American opossum. The species name, ''maculatus'', indicates this species is spotted. Two subspecies ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dasyurus Hallucatus
The northern quoll (''Dasyurus hallucatus''), also known as the northern native cat, the North Australian native cat or the satanellus is a carnivorous marsupial native to Australia. Taxonomy The northern quoll is a member of the family Dasyuridae, and is often stated to be the most distinctive Australian quoll. It was first described in 1842 by naturalist and author John Gould, who gave it the species name ''hallucatus'', which indicates it has a notable first digit. This species has sometimes been placed in a separate genus, ''Satanellus''. Life history The northern quoll is the smallest of the four Australian quoll species. Females are smaller than males, with adult females weighing between and adult males . Head and body length ranges from for adult males and for adult females. The tail length ranges between . Northern quolls feed primarily on invertebrates, but also consume fleshy fruit (particularly figs), and a wide range of vertebrates, including small mammals ...

Dasyurus Geoffroii
The western quoll (''Dasyurus geoffroii'') is Western Australia's largest endemic mammalian carnivore. One of the many marsupial mammals native to Australia, it is also known as the chuditch. The species is currently classed as near-threatened. Taxonomy The western quoll is a member of the family Dasyuridae and is most closely related to the bronze quoll (''Dasyurus spartacus''), a recently described species from New Guinea that was for some time believed to be an outlying population of the western quoll. Its species name, ''geoffroii'', refers to the prominent French naturalist Étienne Geoffroy Saint-Hilaire, who named the genus ''Dasyurus'' in 1796. The species has occasionally been placed in the genus ''Dasyurinus''. It is also known as the chuditch () in Western Australia (from Noongar ''djooditj''); ''chuditch'' serves as both the singular and plural form. Other common names include ''atyelpe'' or ''chilpa'' (from Arrernte), ''kuninka'' (from Western Desert language); '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dasyurus Albopunctatus
The New Guinean quoll (''Dasyurus albopunctatus''), also known as the New Guinea quoll or New Guinea native cat, is a carnivorous marsupial mammal native to New Guinea. It is the second-largest surviving marsupial carnivore of New Guinea. It is known as suatg in the Kalam language of Papua New Guinea.Pawley, Andrew and Ralph Bulmer. 2011. ''A Dictionary of Kalam with Ethnographic Notes''. Canberra. Pacific Linguistics. Taxonomy The New Guinean quoll belongs to Dasyuridae, a family of carnivorous marsupials, which includes other species of quolls, the extinct thylacine, the Tasmanian devil, and many smaller carnivores. It is one of six extant species of quolls, four of which are found in only in Australia and two of which are restricted to New Guinea (the bronze quoll is the other New Guinean species). Both the quolls found in New Guinea seem to be most closely related to the Australian western quoll. Description The New Guinean quoll is small, usually weighing just over 1 ...

Dasyurus
Quolls (; genus ''Dasyurus'') are carnivorous marsupials native to Australia and New Guinea. They are primarily nocturnal and spend most of the day in a den. Of the six species of quoll, four are found in Australia and two in New Guinea. Another two species are known from fossil remains in Pliocene and Pleistocene deposits in Queensland. Genetic evidence indicates that quolls evolved around 15 million years ago in the Miocene, and that the ancestors of the six species had all diverged by around four million years ago. The six species vary in weight and size, from to . They have brown or black fur and pink noses. They are largely solitary, but come together for a few social interactions such as mating which occurs during the winter season. A female gives birth to up to 18 pups, of which only six survive because she only has six teats with which to feed them. They have a life span from 2 to 4 years. Quolls eat smaller mammals, small birds, lizards, and insects. All species hav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
