Spotted-tail Quoll
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] |
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 Kingdom' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wedge-tailed Eagle
The wedge-tailed eagle (''Aquila audax'') is the largest bird of prey in the continent of Australia. It is also found in southern New Guinea to the north and is distributed as far south as the state of Tasmania. Adults of this species have long, broad wings, fully feathered legs, an unmistakable wedge-shaped tail, an elongated maxilla, a strong beak and powerful feet. The wedge-tailed eagle is one of 12 species of large, predominantly dark-coloured booted eagles in the genus '' Aquila'' found worldwide. Genetic research has clearly indicated that the wedge-tailed eagle is fairly closely-related to other, generally large members of the ''Aquila'' genus.Lerner, H., Christidis, L., Gamauf, A., Griffiths, C., Haring, E., Huddleston, C.J., Kabra, S., Kocum, A., Krosby, M., Kvaloy, K., Mindell, D., Rasmussen, P., Rov, N., Wadleigh, R., Wink, M. & Gjershaug, J.O.

Mammals Of Tasmania
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 Sauropsida ...

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, mam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dasyuromorphs
Dasyuromorphia (, meaning "hairy tail" in Greek) is an order comprising most of the Australian carnivorous marsupials, including quolls, dunnarts, the numbat, the Tasmanian devil, and the thylacine. In Australia, the exceptions include the omnivorous bandicoots (order Peramelemorphia) and the marsupial moles (which eat meat but are very different and are now accorded an order of their own, Notoryctemorphia). Numerous South American species of marsupials (orders Didelphimorphia, Paucituberculata, and Microbiotheria) are also carnivorous, as were some extinct members of the order Diprotodontia, including extinct kangaroos (such as ''Ekaltadeta'' and ''Propleopus)'' and thylacoleonids, and some members of the partially extinct clade Metatheria and all members of the extinct superorder Sparassodonta. The order contains four families: one with just a single living species (the numbat), two with only extinct species (including the thylacine and ''Malleodectes''), and one, the Dasyu ...

Tarkine
The Tarkine ( indigenous name: takayna), officially takayna / Tarkine, is an area containing the Savage River National Park in the north west Tasmania, Australia, which contains significant areas of wilderness. The Tarkine is noted for its beauty and natural values, containing the largest area of Gondwanan cool-temperate rainforest in Australia, as well as for its prominence in Tasmania's early mining history. The area's high concentration of Aboriginal sites has led to it being described by the Australian Heritage Council as "one of the world's great archaeological regions". Location The Tarkine is gazetted by the Tasmanian government as unbounded locality in north-west Tasmania The generally accepted definition is the area between the Arthur River in the North, the Pieman River in the south, the ocean to the west and the Murchison Highway in the east. It was first officially recognised in May, 2013, following a recommendation by the Nomenclature Board of Tasmania which was ...

Savage River National Park
Savage River National Park is located in north-west Tasmania, Australia. Established in April 1999, it is the largest undisturbed area of temperate rainforest in Australia since the era of the thylacine. Unlike other national parks of Tasmania, Savage River National Park remains inaccessible to the public, there is no road access or facilities in the park. It is buffered by the Savage River Regional Reserve which has limited 4WD access. The national park is dominated by cool temperate rainforest with extensive stands of myrtle beech dominated rainforest. A significant component of wet scrubland and buttongrass moorland dominate the Baretop Ridge. The park provides valuable habitat for many species of fauna including the Tasmanian devil, dusky antechinus, broad-toothed mouse, wedge-tailed eagle, swift parrot, grey goshawk and the giant freshwater crayfish.

Sodium Fluoroacetate
Sodium fluoroacetate is an organofluorine chemical compound with the formula FCH2CO2Na. This colourless salt has a taste similar to that of sodium chloride and is used as a rodenticide. History and production The effectiveness of sodium fluoroacetate as a rodenticide was reported in 1942. The name "1080" refers to the catalogue number of the poison, which became its brand name. The salt is synthesized by treating sodium chloroacetate with potassium fluoride. Both sodium and potassium salts are derivatives of fluoroacetic acid. Natural occurrence Fluoroacetate occurs naturally in at least 40 plants in Australia, Brazil, and Africa. It is one of only five known organic fluorine-containing natural products. Fluoroacetate occurrence in ''Gastrolobium'' species ''Gastrolobium'' is a genus of flowering plants in the family Fabaceae. This genus consists of over 100 species, and all but two are native to the southwest region of Western Australia, where they are known as "poison peas ...

Endangered Species
An endangered species is a species that is very likely to become extinct in the near future, either worldwide or in a particular political jurisdiction. Endangered species may be at risk due to factors such as habitat loss, poaching and invasive species. The International Union for Conservation of Nature (IUCN) Red List lists the global conservation status of many species, and various other agencies assess the status of species within particular areas. Many nations have laws that protect conservation-reliant species which, for example, forbid hunting, restrict land development, or create protected areas. Some endangered species are the target of extensive conservation efforts such as captive breeding and habitat restoration. Human activity is a significant cause in causing some species to become endangered. Conservation status The conservation status of a species indicates the likelihood that it will become extinct. Multiple factors are considered when assessing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
