Pseudocheiridae
Pseudocheiridae is a family of arboreal marsupials containing 17 extant species of ringtailed possums and close relatives. They are found in forested areas and shrublands throughout Australia and New Guinea. Characteristics Physically, they appear very similar to the pygmy possums, except for their greater size. Even so, they are relatively small animals, with the largest being cat-sized, and they weigh between 200 grams and 2 kilograms. They have grasping hands and feet with opposable first toes on their hindfeet, and, in all species save the greater glider, a prehensile tail. They are nocturnal, with large eyes. All species feed almost entirely on leaves. To enable them to digest this tough and fibrous food, they have an enlarged cecum containing fermenting bacteria, and, like rabbits, they are coprophagous, passing food through their digestive tracts twice. Their teeth include a battery of grinding molars, and they lack lower canines. Their dental formula is: Most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Greater Glider
The greater gliders are three species of large gliding marsupials in the genus ''Petauroides'', all of which are found in eastern Australia. Until 2020 they were considered to be one species, '' Petauroides volans''. In 2020 morphological and genetic differences, obtained using diversity arrays technology, showed there were three species subsumed under this one name. The two new species were named '' Petauroides armillatus'' and '' Petauroides minor''. These species are not closely related to the '' Petaurus'' group of gliding marsupials but instead to the Lemuroid ringtail possum, ''Hemibelideus lemuroides'', with which it shares the subfamily Hemibelideinae. The greater gliders are nocturnal and are solitary herbivores feeding almost exclusively on ''Eucalyptus'' leaves and buds. Like their relative, the lemur-like ringtail, the southern greater glider is found in two forms: a sooty brown form and a grey-to-white form. The central greater glider is instead silvery brown, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phalangeriformes
Phalangeriformes is a paraphyletic suborder of about 70 species of small to medium-sized arboreal locomotion, arboreal marsupials native to Australia, New Guinea, and Sulawesi. The species are commonly known as possums, opossums, gliders, and cuscus. The common name "(o)possum" for various Phalangeriformes species derives from the creatures' resemblance to the opossums of the Americas (the term comes from Powhatan language ''aposoum'' "white animal", from proto-Algonquian language, Proto-Algonquian *''wa·p-aʔɬemwa'' "white dog"). However, although opossums are also marsupials, Australasian possums are more closely related to other Australidelphia, Australasian marsupials such as kangaroos. Phalangeriformes are quadrupedalism, quadrupedal Diprotodontia, diprotodont marsupials with long tails. The smallest species, indeed the smallest diprotodont marsupial, is the Tasmanian pygmy possum, with an adult head-body length of and a weight of . The largest are the two species of be ...

Marsupial
Marsupials are a diverse group of mammals belonging to the infraclass Marsupialia. They are natively found in Australasia, Wallacea, and the Americas. One of marsupials' unique features is their reproductive strategy: the young are born in a relatively undeveloped state and then nurtured within a pouch on their mother's abdomen. Extant marsupials encompass many species, including Kangaroo, kangaroos, Koala, koalas, Opossum, opossums, Phalangeriformes, possums, Tasmanian devil, Tasmanian devils, Wombat, wombats, Wallaby, wallabies, and Bandicoot, bandicoots. Marsupials constitute a clade stemming from the last common ancestor of extant Metatheria, which encompasses all mammals more closely related to marsupials than to Placentalia, placentals. The evolutionary split between placentals and marsupials occurred 125-160 million years ago, in the Middle Jurassic-Early Cretaceous period. Presently, close to 70% of the 334 extant marsupial species are concentrated on the Australian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pseudocheirus
''Pseudocheirus'' is a genus of ringtail possums (family Pseudocheiridae). It includes a single living species, the common ringtail possum (''Pseudocheirus peregrinus'') of Australia, as well as the fossil ''Pseudocheirus marshalli'' from the Pliocene of Victoria. Other species have previously been included in this genus. Most other ringtails—the lemur-like ringtail (''Hemibelideus lemuroides''), the rock-haunting ringtail (''Petropseudes dahli''), and the various species of '' Pseudochirulus'' and '' Pseudochirops''—were classified in ''Pseudocheirus'' until the 1980s or 1990s. A second ringtail from the Victorian Pliocene, '' Petauroides stirtoni'', was originally named as a ''Pseudocheirus'', but is now considered to be more closely related to the greater glider (''Petauroides volans'').Turnbull et al., 2003, p. 533 The genus was erected by William Ogilby in 1837, the same author later using then correcting the spelling ''Pseudochirus'' that is now regarded as a nomencl ...

Hectare
The hectare (; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm2), that is, square metres (), and is primarily used in the measurement of land. There are 100 hectares in one square kilometre. An acre is about and one hectare contains about . In 1795, when the metric system was introduced, the ''are'' was defined as 100 square metres, or one square decametre, and the hectare (" hecto-" + "are") was thus 100 ''ares'' or km2 ( square metres). When the metric system was further rationalised in 1960, resulting in the International System of Units (), the ''are'' was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI and whose use is "expected to continue indefinitely". Though the dekare/decare daa () and are (100 m2) are not officially "accepted for use", they are still used in some contexts. Description The hectare (), although not a unit of SI, is ...

Gestation
Gestation is the period of development during the carrying of an embryo, and later fetus, inside viviparous animals (the embryo develops within the parent). It is typical for mammals, but also occurs for some non-mammals. Mammals during pregnancy can have one or more gestations at the same time, for example in a multiple birth. The time interval of a gestation is called the '' gestation period''. In obstetrics, '' gestational age'' refers to the time since the onset of the last menses, which on average is fertilization age plus two weeks. Mammals In mammals, pregnancy begins when a zygote (fertilized ovum) implants in the female's uterus and ends once the fetus leaves the uterus during labor or an abortion (whether induced or spontaneous). Humans In humans, pregnancy can be defined clinically, biochemically or biologically. Clinically, pregnancy starts from first day of the mother's last period. Biochemically, pregnancy starts when a woman's human chorionic gonado ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mammal Species Of The World
''Mammal Species of the World: A Taxonomic and Geographic Reference'' is a standard reference work in mammalogy giving descriptions and Bibliographic database, bibliographic data for the known species of mammals. It is now in its third edition, published in late 2005, which was edited by Don E. Wilson and DeeAnn M. Reeder. An online version is hosted by Bucknell University, from which the names of the species can be downloaded as a custom dictionary. A partial online version is available at Google Books (see "External links" below). The Checklist Committee is charged with compiling and updating MSW. In its Annual Report for 2015, the Committee noted that it is under contract with Johns Hopkins Press for the 4th edition of MSW, which will be edited by DeeAnn M. Reeder and Kristofer M. Helgen. The database has been made editable for the authors, leading to more frequent website updates. The publication was scheduled for release in 2017, and then deferred until 2019. References ...
