Bridled Nail-tail Wallaby
The bridled nail-tail wallaby (''Onychogalea fraenata''), also known as the bridled nail-tailed wallaby, bridled nailtail wallaby, bridled wallaby, merrin, and flashjack, is a vulnerable species of macropod. It is a small wallaby found in three isolated areas in Queensland, Australia, and whose population is declining. In early 2019 the total population of the species was estimated to be fewer than 500 mature individuals in the wild and 2285 in captivity. Taxonomy A specimen was presented to the Linnean Society of London by John Gould in 1840, and published in the society's journal the following year. The date of first publication has been the source of conjecture, and it has been proposed that this was in a 1840 issue of '' The Athenaeum''. Gould obtained his specimens while in Australia, returning these to England for scientific examination; he gave the animal the common name bridled kangaroo. Description These small wallabies are named for two distinguishing characterist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 North America, n ...

Charters Towers
Charters Towers is a rural town in the Charters Towers Region, Queensland, Australia. It is by road south-west from Townsville on the Flinders Highway. During the last quarter of the 19th century, the town boomed as the rich gold deposits under the city were developed. After becoming uneconomical in the 20th century, profitable mining operations have commenced once again. In the , Charters Towers had a population of 8,120 people. Geography and climate The urban area of the town of Charters Towers includes its suburbs: Charters Towers City (the centre of the city); Richmond Hill, Toll, and Columbia to the north, Queenton to the east, Grand Secret and Alabama Hill to the west, and Towers Hill, Mosman Park, and Millchester to the south. Charters Towers township is only mildly elevated at above sea-level, but this has a noticeable effect, with lower humidity and wider temperature variations compared to nearby Townsville. Charters Towers obtains its water supply from the n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Victoria (Australia)
Victoria is a state in southeastern Australia. It is the second-smallest state with a land area of , the second most populated state (after New South Wales) with a population of over 6.5 million, and the most densely populated state in Australia (28 per km2). Victoria is bordered by New South Wales to the north and South Australia to the west, and is bounded by the Bass Strait to the south (with the exception of a small land border with Tasmania located along Boundary Islet), the Great Australian Bight portion of the Southern Ocean to the southwest, and the Tasman Sea (a marginal sea of the South Pacific Ocean) to the southeast. The state encompasses a range of climates and geographical features from its temperate coastal and central regions to the Victorian Alps in the northeast and the semi-arid north-west. The majority of the Victorian population is concentrated in the central-south area surrounding Port Phillip Bay, and in particular within the metropolit ...

Murray River
The Murray River (in South Australia: River Murray) (Ngarrindjeri: ''Millewa'', Yorta Yorta: ''Tongala'') is a river in Southeastern Australia. It is Australia's longest river at extent. Its tributaries include five of the next six longest rivers of Australia (the Murrumbidgee, Darling, Lachlan, Warrego and Paroo Rivers). Together with that of the Murray, the catchments of these rivers form the Murray–Darling basin, which covers about one-seventh the area of Australia. It is widely considered Australia's most important irrigated region. The Murray rises in the Australian Alps, draining the western side of Australia's highest mountains, then meanders northwest across Australia's inland plains, forming the border between the states of New South Wales and Victoria as it flows into South Australia. From an east–west direction it turns south at Morgan for its final , reaching the eastern edge of Lake Alexandrina, which fluctuates in salinity. The water then flows throu ...

Great Dividing Range
The Great Dividing Range, also known as the East Australian Cordillera or the Eastern Highlands, is a cordillera system in eastern Australia consisting of an expansive collection of mountain ranges, plateaus and rolling hills, that runs roughly parallel to the east coast of Australia and forms the fifth-longest land-based mountain chain in the world, and the longest entirely within a single country. It is mainland Australia's most substantial topographic feature and serves as the definitive watershed for the river systems in eastern Australia, hence the name. The Great Dividing Range stretches more than from Dauan Island in the Torres Strait off the northern tip of Cape York Peninsula, running the entire length of the eastern coastline through Queensland and New South Wales, then turning west across Victoria before finally fading into the Wimmera plains as rolling hills west of the Grampians region. The width of the Range varies from about to over .Shaw, John H., ''Col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
History Of Australia (1788–1850)
The history of Australia from 1788 to 1850 covers the early British colonial period of Australia's history. This started with the arrival in 1788 of the First Fleet of British ships at Port Jackson on the lands of the Eora, and the establishment of the penal colony of New South Wales as part of the British Empire. It further covers the European scientific exploration of the continent and the establishment of the other Australian colonies that make up the modern states of Australia. After several years of privation, the penal colony gradually expanded and developed an economy based on farming, fishing, whaling, trade with incoming ships, and construction using convict labour. By 1820, however, British settlement was largely confined to a 100 kilometre radius around Sydney and to the central plain of Van Diemen's land. From 1816 penal transportation to Australia increased rapidly and the number of free settlers grew steadily. Van Diemen's Land became a separate colony in 1825, ...

Immune System
The immune system is a network of biological processes that protects an organism from diseases. It detects and responds to a wide variety of pathogens, from viruses to parasitic worms, as well as cancer cells and objects such as wood splinters, distinguishing them from the organism's own healthy tissue. Many species have two major subsystems of the immune system. The innate immune system provides a preconfigured response to broad groups of situations and stimuli. The adaptive immune system provides a tailored response to each stimulus by learning to recognize molecules it has previously encountered. Both use molecules and cells to perform their functions. Nearly all organisms have some kind of immune system. Bacteria have a rudimentary immune system in the form of enzymes that protect against virus infections. Other basic immune mechanisms evolved in ancient plants and animals and remain in their modern descendants. These mechanisms include phagocytosis, antimicrobial pe ...

Red Foxes In Australia
Red foxes pose a serious conservation problem in Australia. 2012 estimates indicate that there are more than 7.2 million red foxes (''Vulpes vulpes'') and growing with a range extending throughout most of the continental mainland. The species became established in Australia through successive introductions by settlers in 1830s. Due to its rapid spread and ecological impact it has classified as one of the most damaging invasive species in Australia. Introduction and spread Red foxes were introduced to the British colonies of Van Diemen's Land (as early as 1833) and the Port Phillip District and Sydney Regions of New South Wales (as early as 1845) for the purpose of the traditional English sport of fox hunting. Curiously a permanent fox population was not established on the island of Tasmania and it is widely held that they were outcompeted by the Tasmanian devil. On the mainland, however, the species was successful as an apex predator. The spread of red foxes across the south ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feral Cats In Australia
Cats are an invasive species in Australia. Because they are not native to Australia and were only introduced by colonisers as pets in the early 1800s, native Australian animals did not co-evolve with them. , some 3.8 million domestic cats and up to 6.3 million feral cats continue to live in Australia. Every year domestic and feral cats in Australia kill 1,067,000,000 mammals, 399,000,000 birds, 609,000,000 reptiles, and 92,000,000 frogs. As one of the most ecologically damaging and the most costly invasive species in Australia, predation by both domestic and feral cats has played a role in the extinction of many of Australia's Indigenous animals. For instance, cats are found to have significantly contributed to the extinction of at least 22 endemic Australian mammals since the arrival of Europeans. For biosecurity reasons, any cats that are imported into Australia must meet conditions set by the Department of Agriculture, Fisheries and Forestry. Historical context Historica ...
