Squirrel Glider
The squirrel glider (''Petaurus norfolcensis'') is a nocturnal gliding possum. The squirrel glider is one of the wrist-winged gliders of the genus ''Petaurus''. Habitat This species' home range extends from Bordertown near the South Australian/Victorian Border through south-eastern Australia to northern Queensland. This species was thought to be extinct in South Australia since 1939 until a genetic test confirmed their inhabitance in this area. The squirrel glider lives in south-eastern Australia in the dry sclerophyll forest and woodlands. In Queensland, however, they occupy a wetter eucalypt forest. The glider will make a den in the hollow tree and line it with leaves. Here it will sleep and usually lives in groups of one male, 2 females, and offspring. Appearance Like most of the wrist-winged gliders, the squirrel glider is endemic to Australia. It is about twice the size of the related sugar glider (''P. breviceps''). Its body is 18–23 cm long and its tail meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Robert Kerr (writer)
Dr Robert Kerr FRSE FAS FRCSE (20 October 1757 – 11 October 1813) was a Scottish surgeon, writer on scientific and other subjects, and translator. Life Kerr was born in 1757 in Bughtridge, Roxburghshire, the son of James Kerr, a jeweller, who served as MP for Edinburgh 1747–1754, and his wife Elizabeth. He was sent to the High School in Edinburgh. He studied medicine at the University of Edinburgh and practised at the Edinburgh Foundling Hospital as a surgeon. He was elected a Fellow of the Royal Society of Edinburgh in 1788. His proposers were Alexander Fraser Tytler, James Russell and Andrew Dalzell. At this time he lived at Foresters Wynd off the Royal Mile in Edinburgh. He translated several scientific works into English, such as Antoine Lavoisier's work of 1789, '' Traité Élémentaire de Chimie'', published under the title ''Elements of Chemistry in a New Systematic Order containing All the Modern Discoveries'', in 1790. In 1792, he published ''The Animal Kingdo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opi ...

Extinct Mammals Of South Australia
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] |
Mammals Of Victoria (Australia)
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 S ...

Marsupials Of Australia
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 North ...

Gliding Possums
Gliding is a recreational activity and competitive air sport in which pilots fly unpowered aircraft known as gliders or sailplanes using naturally occurring currents of rising air in the atmosphere to remain airborne. The word ''soaring'' is also used for the sport. Gliding as a sport began in the 1920s. Initially the objective was to increase the duration of flights but soon pilots attempted cross-country flights away from the place of launch. Improvements in aerodynamics and in the understanding of weather phenomena have allowed greater distances at higher average speeds. Long distances are now flown using any of the main sources of rising air: ridge lift, thermals and lee waves. When conditions are favourable, experienced pilots can now fly hundreds of kilometres before returning to their home airfields; occasionally flights of more than are achieved. Some competitive pilots fly in races around pre-defined courses. These gliding competitions test pilots' abilities to m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Petauridae
Petauridae is a family of possums containing 13 species: four species of trioks and striped possum (genus ''Dactylopsila''), eight species of wrist-winged glider (genus ''Petaurus''), and Leadbeater's possum (''Gymnobelideus leadbeateri''), which has only vestigial gliding membranes. Most of the wrist-winged gliders are native to Australia, whereas most of the striped possums to New Guinea, but some members of each group are found on both sides of the Torres Strait. Leadbeater's possum is endemic to Victoria, Australia. Evolution All petaurids have obvious facial markings, a well-defined dorsal stripe, very large lower front incisors, and four-cusped molars. Despite their distinctive appearance, petaurids are closely related to the ringtail possums (family Pseudocheiridae) and are grouped together with them to form the superfamily Petauroidea. The wrist-winged gliders are omnivorous, specialising on sap and nectar, but taking a wide variety of supplemental foods. The gliders ...
