Rabbits In Australia
European rabbits (''Oryctolagus cuniculus'') were first introduced to Australia in the 18th century with the First Fleet, and later became widespread, 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 previous nu ... [...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 (, “dug up”) and (, “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.

Botany Bay
Botany Bay (Dharawal language, Dharawal: ''Kamay'') is an open oceanic embayment, 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 Sans Souci, New South Wales, Sans Souci as well as the Cooks River at Kyeemagh, which flows to the east before meeting its river mouth, mouth at the Tasman Sea, midpoint between the suburbs of La Perouse, New South Wales, 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 port, seaport, located at Port Botany (seaport), Port Botany, with Port operator, facilities managed by Port Authority of New South Wales, Sydney Ports Cor ...

Great Depression In Australia
Australia was affected 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 had 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 Australia ...

Unintended Consequences
In the social sciences, unintended consequences (sometimes unanticipated consequences or unforeseen consequences, more colloquially called knock-on effects) are outcomes of a purposeful action that are not intended or foreseen. The term was popularized in the 20th century by American sociologist Robert K. Merton. and later used to prevent erosion in earthworks, has become a major problem in the Southeastern United States. Kudzu has displaced native plants and has effectively taken over significant portions of land. The protection of the steel industry in the United States reduced production of steel in the United States, increased costs to users, and increased unemployment in associated industries. Perverse results In 2003, Barbra Streisand unsuccessfully sued Kenneth Adelman and Pictopia.com for posting a photograph of her home online. Before the lawsuit had been filed, only 6 people had downloaded the file, two of them Streisand's attorneys. The lawsuit drew attention to t ...

Hunting
Hunting is the Human activity, human practice of seeking, pursuing, capturing, and killing wildlife or feral animals. The most common reasons for humans to hunt are to obtain the animal's body for meat and useful animal products (fur/hide (skin), hide, bone/tusks, horn (anatomy), horn/antler, etc.), for recreation/taxidermy (see trophy hunting), although it may also be done for resourceful reasons such as removing predators dangerous to humans or domestic animals (e.g. wolf hunting), to pest control, eliminate pest (organism), pests and nuisance animals that damage crops/livestock/poultry or zoonosis, spread diseases (see varmint hunting, varminting), for trade/tourism (see safari), or for conservation biology, ecological conservation against overpopulation and invasive species (commonly called a culling#Wildlife, cull). Recreationally hunted species are generally referred to as the ''game (food), game'', and are usually mammals and birds. A person participating in a hunt is a ...

Rabbit Skins
Rabbits are small mammals in the family Leporidae (which also includes the hares), which is in the order Lagomorpha (which also includes pikas). They are familiar throughout the world as a small herbivore, a prey animal, a domesticated form of livestock, and a pet, having a widespread effect on ecologies and cultures. The most widespread rabbit genera are ''Oryctolagus'' and ''Sylvilagus''. The former, ''Oryctolagus'', includes the European rabbit, ''Oryctolagus cuniculus'', which is the ancestor of the hundreds of breeds of domestic rabbit and has been introduced on every continent except Antarctica. The latter, ''Sylvilagus'', includes over 13 wild rabbit species, among them the cottontails and tapetis. Wild rabbits not included in ''Oryctolagus'' and ''Sylvilagus'' include several species of limited distribution, including the pygmy rabbit, volcano rabbit, and Sumatran striped rabbit. Rabbits are a paraphyletic grouping, and do not constitute a clade, as hares (belonging ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Heredity, heritable traits characteristic of a population over generations. Charles Darwin popularised the term "natural selection", contrasting it with selective breeding, artificial selection, which is intentional, whereas natural selection is not. Genetic diversity, Variation of traits, both Genotype, genotypic and phenotypic, exists within all populations of organisms. However, some traits are more likely to facilitate survival and reproductive success. Thus, these traits are passed the next generation. These traits can also become more Allele frequency, common within a population if the environment that favours these traits remains fixed. If new traits become more favoured due to changes in a specific Ecological niche, niche, microevolution occurs. If new traits become more favoured due to changes in the ...

Population Explosion
Overpopulation or overabundance is a state in which the population of a species is 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 are often 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 crowd other species out of existence. Background In ecology, overpopulation is a concept used primarily in ... [...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 ...
