Feral Donkeys In Australia
Feral donkeys were first brought to Australia as pack animals to replace horses, which had succumbed to native poisonous plants. Now numbering 5 million, they have been declared a pest, owing to their damage to vegetation and erosion of soil. Culling is mainly carried out by marksmen in helicopters, and experiments are being made in fertility control. History Feral donkeys in Australia (and elsewhere) are donkeys (scientific name ''Equus asinus'') which escaped from captivity, and are living and breeding in the wild. Donkeys originated in Africa and in parts of Asia. They are a part of the family Equidae. While donkeys display many horse-like characteristics, they are more closely related to wild asses. Donkeys were brought to Australia from 1866 for use as pack and haulage animals. Up until that point, the Australians had been using the horse as their main mode of transportation. However, problems arose when the horses used in transportation began to become sickened by some of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wild Ass
The wild asses (''Asinus'') are a subgenus of single toed grazing ungulates. Its species are: *African wild ass ''Equus africanus'' **Nubian wild ass ''Equus africanus africanus'' (likely ancestor of the domestic donkey) **Somali wild ass ''Equus africanus somaliensis'' *Kiang (Tibetan wild ass, ''khyang'', or ''gorkhar'') ''Equus kiang'' ** Eastern kiang ''Equus kiang holdereri'' ** Southern kiang ''Equus kiang polyodon'' ** Western kiang ''Equus kiang kiang'' *Onager (Asiatic wild ass) ''Equus hemionus'' **Indian wild ass (''khur''), ''Equus hemionus khur'' **Mongolian wild ass (''khulan''), ''Equus hemionus hemionus'' **Persian onager (''gur''), ''Equus hemionus onager'' **Syrian wild ass (''hemippe''), ''Equus hemionus hemippus'' (extinct) **Turkmenian kulan The Turkmenian kulan (''Equus hemionus kulan''), also called Transcaspian wild ass, Turkmenistani onager or simply the ', is a subspecies of onager (Asiatic wild ass) native to Central Asia.

Australian Megafauna
The term Australian megafauna refers to the megafauna in Australia during the Pleistocene Epoch. Most of these species became extinct during the latter half of the Pleistocene, and the roles of human and climatic factors in their extinction are contested. There are similarities between the prehistoric Australian megafauna and some mythical creatures from the Aboriginal Dreamtime. Causes of extinction Many modern researchers, including Tim Flannery, think that with the arrival of early Aboriginal Australians (around 70,000~65,000 years ago), hunting and the use of fire to manage their environment may have contributed to the extinction of the megafauna. Increased aridity during peak glaciation (about 18,000 years ago) may have also contributed, but most of the megafauna were already extinct by this time. Others, including Steve Wroe, note that records in the Australian Pleistocene are rare, and there is not enough data to definitively determine the time of extinction of many o ...

Fauna Naturalised In Australia
Fauna is all of the animal life present in a particular region or time. The corresponding term for plants is ''flora'', and for fungi, it is ''funga''. Flora, fauna, funga and other forms of life are collectively referred to as '' biota''. Zoologists and paleontologists use ''fauna'' to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna". Paleontologists sometimes refer to a sequence of faunal stages, which is a series of rocks all containing similar fossils. The study of animals of a particular region is called faunistics. Etymology ''Fauna'' comes from the name Fauna, a Roman goddess of earth and fertility, the Roman god Faunus, and the related forest spirits called Fauns. All three words are cognates of the name of the Greek god Pan, and ''panis'' is the Greek equivalent of fauna. ''Fauna'' is also the word for a book that catalogues the animals in such a manner. The term was first used by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Donkeys
The domestic donkey is a hoofed mammal in the family Equidae, the same family as the horse. It derives from the African wild ass, ''Equus africanus'', and may be classified either as a subspecies thereof, ''Equus africanus asinus'', or as a separate species, ''Equus asinus''. It was domesticated in Africa some years ago, and has been used mainly as a working animal since that time. There are more than 40 million donkeys in the world, mostly in underdeveloped countries, where they are used principally as draught or pack animals. While working donkeys are often associated with those living at or below subsistence, small numbers of donkeys or asses are kept for breeding or as pets in developed countries. A male donkey is known as a ''jack'' or ''jackass'', a female is a ''jenny'' or ''jennet'', and an immature donkey of either sex is a ''foal''. Jacks are often mated with female horses (mares) to produce '' mules''; the less common hybrid of a male horse (stallion) and je ...

Australian Feral Camel
Australian feral camels are feral populations of dromedaries (''Camelus dromedarius'') in Australia. Imported from British India and Afghanistan during the 19th century for transport and construction during the colonisation of the central and western parts of Australia, many were released into the wild after motorised transport replaced the use of camels in the early 20th century, resulting in a fast-growing feral population. By 2008, it was ncorrectlyfeared that Central Australia's feral camel population had grown to about one million and was projected to double every 8 to 10 years. Camels are known to cause serious degradation of local environmental and cultural sites, particularly during dry conditions. Pastoralists, representatives from the Central Land Council, and Aboriginal land holders in the relevant areas were those amongst the complainants. An AU$19 million culling program was funded in 2009, and by 2013 a total of 160,000 camels were slaughtered, estimating the fe ...

Traditional Chinese Medicine
Traditional Chinese medicine (TCM) is an alternative medical practice drawn from traditional medicine in China. It has been described as "fraught with pseudoscience", with the majority of its treatments having no logical mechanism of action. Medicine in traditional China encompassed a range of sometimes competing health and healing practices, folk beliefs, literati theory and Confucian philosophy, herbal remedies, food, diet, exercise, medical specializations, and schools of thought. In the early twentieth century, Chinese cultural and political modernizers worked to eliminate traditional practices as backward and unscientific. Traditional practitioners then selected elements of philosophy and practice and organized them into what they called "Chinese medicine" (''Zhongyi''). In the 1950s, the Chinese government sponsored the integration of Chinese and Western medicine, and in the Great Proletarian Cultural Revolution of the 1960s, promoted Chinese medicine as inexpensive a ...

Donkey-hide Gelatin
Donkey-hide gelatin or ass-hide glue ( la, colla corii asini) is gelatin obtained from the skin of the donkey (''Equus asinus'') by soaking and stewing. It is used as an ingredient in the traditional medicine of China, where it is called ejiao (). The gelatin is produced in several coastal provinces of China: Jiangsu, Zhejiang, Shandong. Shandong's Dong'e County was where "ejiao" got its name. According to a ca. 1723 account by the French Jesuit Dominique Parrenin, there was a well in Dong'e which was normally kept closed and sealed, and which was only opened when water was taken to be used in preparation of ''ejiao'' for the emperor's court. (This is a reprint; the original text was published in the first half of the 18th century. ''E xian'' (for Dong'e) and ''Ejiao'' are transcribed ''Ngo-hien'' and ''Ngo-kiao'', under the transcription system then in use). Manufacture According to Parennin, the product was traditionally prepared during the late fall and winter (from after ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trafficking
Smuggling is the illegal transportation of objects, substances, information or people, such as out of a house or buildings, into a prison, or across an international border, in violation of applicable laws or other regulations. There are various motivations to smuggle. These include the participation in illegal trade, such as in the drug trade, illegal weapons trade, prostitution, human trafficking, kidnapping, exotic wildlife trade, art theft, heists, chop shops, illegal immigration or illegal emigration, tax evasion, import/export restrictions, providing contraband to prison inmates, or the theft of the items being smuggled. Smuggling is a common theme in literature, from Bizet's opera ''Carmen'' to the James Bond spy books (and later films) '' Diamonds Are Forever'' and '' Goldfinger''. Etymology The verb ''smuggle'', from Low German ''smuggeln'' or Dutch ''smokkelen'' (="to transport (goods) illegally"), apparently a frequentative formation of a word meaning "to sneak", ...

Helicopter
A helicopter is a type of rotorcraft in which lift and thrust are supplied by horizontally spinning rotors. This allows the helicopter to take off and land vertically, to hover, and to fly forward, backward and laterally. These attributes allow helicopters to be used in congested or isolated areas where fixed-wing aircraft and many forms of STOL (Short TakeOff and Landing) or STOVL (Short TakeOff and Vertical Landing) aircraft cannot perform without a runway. In 1942, the Sikorsky R-4 became the first helicopter to reach full-scale production.Munson 1968.Hirschberg, Michael J. and David K. Dailey"Sikorsky". ''US and Russian Helicopter Development in the 20th Century'', American Helicopter Society, International. 7 July 2000. Although most earlier designs used more than one main rotor, the configuration of a single main rotor accompanied by a vertical anti-torque tail rotor (i.e. unicopter, not to be confused with the single-blade monocopter) has become the most comm ...

Muster (horse)
A muster (Au/NZ) or a roundup (US/Ca) is the process of gathering livestock. Musters usually involve cattle, sheep or horses, but may also include goats, camels, buffalo or other animals. Mustering may be conducted for a variety of reasons including routine livestock health checks and treatments, branding, shearing, lamb marking, sale, feeding and transport or droving to another location. Mustering is a long, difficult and sometimes dangerous job, especially on the vast Australian cattle stations of the Top End, 'The Falls' (gorge) country of the Great Dividing Range and the ranches of the western United States. The group of animals gathered in a muster is referred to as a "mob" in Australia and a "herd" in North America. Methods Mustering may be done on foot, with various vehicles, horses or with aircraft. Techniques in mustering cattle or sheep will depend on region, culture, distances and the type of terrain involved, and the type of animal that is being mustered. Most she ...
