Rabbits In Australia
European rabbits (''Oryctolagus cuniculus'') were first introduced to Australia in the 18th century with the First Fleet, and later became widespread likely because of Thomas Austin. Such wild rabbit populations are a serious mammalian pest and invasive species in Australia causing millions of dollars’ worth of damage to crops. Their spread may have been enhanced through the emergence of strong crossbreeds. Various methods in the 20th century have been attempted to control the Australian rabbit population. Conventional methods include shooting rabbits and destroying their warrens, but these had only limited success. From 1901 to 1907, a rabbit-proof fence was built in Western Australia in an unsuccessful attempt to contain the rabbits. The'' myxoma virus'', which causes myxomatosis, was introduced into the rabbit population in the 1950s and had the effect of severely reducing the rabbit population. However, the survivors have since adapted and partially recovered their prev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oryctolagus Cuniculus Tasmania 2
''Oryctolagus'' is a genus of lagomorph that today contains the European rabbit and its descendant, the domestic rabbit, as well as several fossil species. The generic name derives from Ancient Greek ὀρυκτός (''oryktos'', “dug up”) and λαγώς (''lagōs'', “hare”). Evolution ''Oryctolagus'' first appeared at the end of the Miocene, around 6.5 MYA. Fossil remains from the middle Pliocene led to the recognition of two species, '' Oryctolagus lacosti'' in southern France and northwestern Italy and '' Oryctolagus laynensis'' in the Iberian Peninsula. This latter form is thought to be the origin of the extant species. Species *''Oryctolagus cuniculus The European rabbit (''Oryctolagus cuniculus'') or coney is a species of rabbit native to the Iberian Peninsula (including Spain, Portugal, and southwestern France), western France, and the northern Atlas Mountains in northwest Africa.

Botany Bay
Botany Bay (Dharawal: ''Kamay''), an open oceanic embayment, is located in Sydney, New South Wales, Australia, south of the Sydney central business district. Its source is the confluence of the Georges River at Taren Point and the Cooks River at Kyeemagh, which flows to the east before meeting its mouth at the Tasman Sea, midpoint between the suburbs of La Perouse and Kurnell. The northern headland of the entrance to the bay from the Tasman Sea is Cape Banks and, on the southern side, the outer headland is Cape Solander and the inner headland is Sutherland Point. The total catchment area of the bay is approximately . Despite its relative shallowness, the bay now serves as greater metropolitan Sydney's main cargo seaport, located at Port Botany, with facilities managed by Sydney Ports Corporation. Two runways of Sydney Airport extend into the bay, as do some port facilities. Botany Bay National Park is located on the northern and southern headlands of the bay. ...

Great Depression In Australia
Australia suffered badly during the period of the Great Depression of the 1930s. The Depression began with the Wall Street Crash of 1929 and rapidly spread worldwide. As in other nations, Australia suffered years of high unemployment, poverty, low profits, deflation, plunging incomes, and lost opportunities for economic growth and personal advancement. The Australian economy and foreign policy largely rested upon its place as a primary producer within the British Empire, and Australia's important export industries, particularly primary products such as wool and wheat, suffered significantly from the collapse in international demand. Unemployment reached a record high of around 30% in 1932, and gross domestic product declined by 10% between 1929 and 1931. There were also incidents of civil unrest, particularly in Australia's largest city, Sydney. Though Australian Communist and far right movements were active in the Depression, they remained largely on the periphery of Aust ...

Unintended Consequences
In the social sciences, unintended consequences (sometimes unanticipated consequences or unforeseen consequences) are outcomes of a purposeful action that are not intended or foreseen. The term was popularised in the twentieth century by American sociologist Robert K. Merton and expanded by economist Thomas Sowell and psychologist Stuart Vyse.Robert K. Merton, Versatile Sociologist and Father of the Focus Group, Dies at 92 Michael T. Kaufman, '''' Unintended consequences can be grouped into three types: * ''Unexpected benefit'': ...

Winchelsea, Victoria
Winchelsea is a town in Victoria, Australia. The town is located in the Surf Coast Shire local government area, the suburb or locality of Winchelsea is predominantly within Surf Coast Shire with a small section within the Colac Otway Shire. Winchelsea is located on the Barwon River 115 km south-west of Melbourne and close to Geelong (37 km north-east). History The first Europeans to reside in the area were squatters (Lomas's) who established grazing runs there c. 1837. Thomas Austin migrated from Tasmania and occupied the present day site of Winchelsea in 1837. The area was then called Austin's Ford. Austin built up his estate of Barwon Park to , including a mansion which still stands today. The town developed around the Barwon Inn, established in 1842 by Prosper Nicholas Trebeck and Charles Bea The Post Office opened as Barwon on 1 July 1848 and was renamed Winchelsea in 1854. The town was the administrative centre of the Shire of Winchelsea, which was proclaime ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hunting
Hunting is the human practice of seeking, pursuing, capturing, or killing wildlife or feral animals. The most common reasons for humans to hunt are to harvest food (i.e. meat) and useful animal products ( fur/ hide, bone/tusks, horn/antler, etc.), for recreation/taxidermy (see trophy hunting), to remove predators dangerous to humans or domestic animals (e.g. wolf hunting), to eliminate pests and nuisance animals that damage crops/livestock/poultry or spread diseases (see varminting), for trade/tourism (see safari), or for ecological conservation against overpopulation and invasive species. Recreationally hunted species are generally referred to as the ''game'', and are usually mammals and birds. A person participating in a hunt is a hunter or (less commonly) huntsman; a natural area used for hunting is called a game reserve; an experienced hunter who helps organize a hunt and/or manage the game reserve is known as a gamekeeper. Many non-human animals also hunt (see p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rabbit Skins
Rabbits, also known as bunnies or bunny rabbits, are small mammals in the family Leporidae (which also contains the hares) of the order Lagomorpha (which also contains the pikas). ''Oryctolagus cuniculus'' includes the European rabbit species and its descendants, the world's 305 breeds of domestic rabbit. ''Sylvilagus'' includes 13 wild rabbit species, among them the seven types of cottontail. The European rabbit, which has been introduced on every continent except Antarctica, is familiar throughout the world as a wild prey animal and as a domesticated form of livestock and pet. With its widespread effect on ecologies and cultures, the rabbit is, in many areas of the world, a part of daily life—as food, clothing, a companion, and a source of artistic inspiration. Although once considered rodents, lagomorphs like rabbits have been discovered to have diverged separately and earlier than their rodent cousins and have a number of traits rodents lack, like two extra inci ...

Natural Selection
Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with artificial selection, which in his view is intentional, whereas natural selection is not. Variation exists within all populations of organisms. This occurs partly because random mutations arise in the genome of an individual organism, and their offspring can inherit such mutations. Throughout the lives of the individuals, their genomes interact with their environments to cause variations in traits. The environment of a genome includes the molecular biology in the cell, other cells, other individuals, populations, species, as well as the abiotic environment. Because individuals with certain variants of the trait tend to survive and reproduce more than individuals ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Population Explosion
Overpopulation or overabundance is a phenomenon in which a species' population becomes larger than the carrying capacity of its environment. This may be caused by increased birth rates, lowered mortality rates, reduced predation or large scale migration, leading to an overabundant species and other animals in the ecosystem competing for food, space, and resources. The animals in an overpopulated area may then be forced to migrate to areas not typically inhabited, or die off without access to necessary resources. Judgements regarding overpopulation always involve both facts and values. Animals often are judged overpopulated when their numbers cause impacts that people find dangerous, damaging, expensive, or otherwise harmful. Societies may be judged overpopulated when their human numbers cause impacts that degrade ecosystem services, decrease human health and well-being, or crowed other species out of existence. Background In ecology, overpopulation is a concept used primarily ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Australian Register
''The Register'', originally the ''South Australian Gazette and Colonial Register'', and later ''South Australian Register,'' was South Australia's first newspaper. It was first published in London in June 1836, moved to Adelaide in 1837, and folded into '' The Advertiser'' almost a century later in February 1931. The newspaper was the sole primary source for almost all information about the settlement and early history of South Australia. It documented shipping schedules, legal history and court records at a time when official records were not kept. According to the National Library of Australia, its pages contain "one hundred years of births, deaths, marriages, crime, building history, the establishment of towns and businesses, political and social comment". All issues are freely available online, via Trove. History ''The Register'' was conceived by Robert Thomas, a law stationer, who had purchased for his family of land in the proposed South Australian province after b ...

Anlaby Estate
Anlaby or Anlaby Station is a pastoral lease located about south east of Marrabel and north of Kapunda in the state of South Australia. History The locality was first explored by Europeans in March 1838 by the party of Hill, Wood, Willis, and Oakden, who were scouting an overlanding route from the Murray. The station is the oldest merino stud in Australia and was settled in 1839 by Capt. John Finnis, who called it "Mount Dispersion" (the Aboriginal name was ''Pudna''), and stocked it with 12,000 sheep. The property was acquired in 1841 by Frederick Dutton, at which time it was at the frontier of European settlement. In the early days Anlaby extended from near Kapunda to Tothill's Creek occupying an area of with a length of and a width of . The neighbouring pastoralist to the west and north was W. S. Peter, while to the south was Bagot's ''Koonunga''. To the east was the Murray scrub. A two-man mounted police station was established at Julia Creek between 1842 and ...
