List Of Introduced Species
A complete list of introduced species for even quite small areas of the world would be dauntingly long. Humans have introduced more different species to new environments than any single document can record. This list is generally for established species with truly wild populations— not kept domestically, that have been seen numerous times, and have breeding populations. While most introduced species can cause a negative impact to new environments they reach, some can have a positive impact, just for conservation purpose.

Introduced Species
An introduced species, alien species, exotic species, adventive species, immigrant species, foreign species, non-indigenous species, or non-native species is a species living outside its native distributional range, but which has arrived there by human activity, directly or indirectly, and either deliberately or accidentally. Non-native species can have various effects on the local ecosystem. Introduced species that become established and spread beyond the place of introduction are considered naturalized. The process of human-caused introduction is distinguished from biological colonization, in which species spread to new areas through "natural" (non-human) means such as storms and rafting. The Latin expression neobiota captures the characteristic that these species are ''new'' biota to their environment in terms of established biological network (e.g. food web) relationships. Neobiota can further be divided into neozoa (also: neozoons, sing. neozoon, i.e. animals) and ne ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Indian Hog Deer
The Indian hog deer (''Axis porcinus''), or Indochinese hog deer, is a small cervid native to the region of the Indian subcontinent and Indo-Gangetic Plain. Introduced populations are established in Australia, as well as the United States and Sri Lanka. Its name derives from the Hog (swine), hog-like manner in which it runs through forests (with its head hung low), to ease ducking under obstacles instead of leaping over them, like most other deer. Taxonomy ''Cervus porcinus'' was the scientific name used by Eberhard August Wilhelm von Zimmermann in 1777 and 1780, based on an earlier description of Indian hog deer brought to England from India. It was placed in the genus ''Axis (genus), Axis'' by William Jardine (naturalist), William Jardine in 1835 and by Brian Houghton Hodgson in 1847. In 2004, it was proposed to be placed in the genus ''Hyelaphus''. The proposal has not been accepted, with most authors keeping it under ''Axis''. A subspecies, ''A. p. annamiticus'', was once c ...

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] |
Northern Palm Squirrel
The northern palm squirrel (''Funambulus pennantii''), also called the five-striped palm squirrel, is a species of rodent in the family Sciuridae. Some authorities recognize two subspecies, ''F. p. pennantii'' and ''F. p. argentescens''. It is a semi-arboreal species found in tropical and subtropical dry deciduous forests and many other rural and urban habitats. It is a common species with a wide range and the International Union for Conservation of Nature has rated its conservation status as being of "least concern". Distribution It is found in the Andaman Islands, Nicobar Islands (where it was introduced), India, Nepal, Bangladesh, Pakistan and Iran. In India, it is fairly common in urban areas, even in large cities such as Delhi and Kolkata. Two subspecies, ''Funambulus pennantii argentescens'' and ''Funambulus pennantii lutescens'', were suggested by Wroughton in addition to the nominate race; however, more recent workers do not make this distinction. Thorington and Hoffma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
House Mouse
The house mouse (''Mus musculus'') is a small mammal of the rodent family Muridae, characteristically having a pointed snout, large rounded ears, and a long and almost hairless tail. It is one of the most abundant species of the genus '' Mus''. Although a wild animal, the house mouse has benefited significantly from associating with human habitation to the point that truly wild populations are significantly less common than the synanthropic populations near human activity. The house mouse has been domesticated as the pet or fancy mouse, and as the laboratory mouse, which is one of the most important model organisms in biology and medicine. The complete mouse reference genome was sequenced in 2002. Characteristics House mice have an adult body length (nose to base of tail) of and a tail length of . The weight is typically . In the wild they vary in color from grey and light brown to black (individual hairs are actually agouti coloured), but domesticated fancy mice and l ...

Feral Cat
A feral cat or a stray cat is an unowned domestic cat (''Felis catus'') that lives outdoors and avoids human contact; it does not allow itself to be handled or touched, and usually remains hidden from humans. Feral cats may breed over dozens of generations and become a local apex predator in urban, savannah and bushland environments, and especially on islands where native animals did not evolve alongside predators. Some feral cats may become more comfortable with people who regularly feed them, but even with long-term attempts at socialization of animals, socialization, they usually remain aloof and reject human touch. Of the 700 million cats in the world, an estimated 480 million are feral. Feral cats are devastating to wildlife, and conservation biologists consider them to be one of the worst invasive species on Earth. They are included in the list of 100 of the World's Worst Invasive Alien Species, the world's 100 worst invasive alien species. Attempts to control feral cat ...

Free-ranging Dog
A free-ranging dog is a dog that is not confined to a yard or house. Free-ranging dogs include street dogs, village dogs, stray dogs, feral dogs, etc., and may be owned or unowned. The global dog population is estimated to be 900 million, of which around 20% are regarded as owned pets and therefore restrained. Free-ranging dogs are common in developing countries. It is estimated that there are about 62 million free-ranging dogs in India. In Western countries free-ranging dogs are rare; in Europe they are primarily found in parts of Eastern Europe, and, to a lesser extent, in parts of Southern Europe. Various human organizations work to manage free-ranging dogs, citing concerns about the spread of rabies, the animals' welfare, and other areas. These include governments, animal rights organizations and other non-governmental organizations, and veterinarians. Some governments have dog-management policies, including trap–neuter–return, the permanent removal of dogs from the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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, beginning around the 1830s. Due to its rapid spread and ecological impact, it has been classified as one of the most damaging invasive species in Australia. Introduction and spread European red foxes were introduced to the British colonies of Van Diemen's Land as early as 1833, and to the Port Phillip District and Sydney Regions of New South Wales as early as 1845; introductions were, originally, intended to uphold the traditional English sport of fox hunting. Curiously, prior to 2010, 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 and the now-extinct thylacin ...

European Hare
The European hare (''Lepus europaeus''), also known as the brown hare, is a species of hare native to Europe and parts of Asia. It is among the largest hare species and is adapted to temperate, open country. Hares are herbivorous and feed mainly on grasses and herbs, supplementing these with twigs, buds, bark and field crops, particularly in winter. Their natural Predation, predators include large birds of prey, canidae, canids and felids. They rely on high-speed endurance running to escape predation, having long, powerful limbs and large nostrils. Generally nocturnal and shy in nature, hares change their behaviour in the spring, when they can be seen in broad daylight chasing one another around in fields. During this spring frenzy, they sometimes strike one another with their paws ("boxing"). This is not just competition between males, but also a female hitting a male, either to show she is not yet ready to mate or to test his determination. The female nests in a depression on t ...

Feral Goats In Australia
Feral goats are an invasive animal species in Australia. First arriving in the 18th century with European settlers, feral goat populations originated from escaped domestic individuals. Today, feral goats are found across Australia, where they cause economic and environmental damage through overgrazing and competition with livestock and native marsupials. History Feral goats came to Australia with the first fleet in 1788. For instance, cashmere goats were brought into South Australia in 1837. In the 1860s, angora goats and cashmere goats were imported from Asia in an order to start a goat fibre industry. Some herds were set free when the industry collapsed in the 1920s. Goats were also taken around Australia with settlers, railway construction groups and miners. The recent populations of the feral goat have established from goats used to control weeds in plantation forests and woody weeds in inland New South Wales and Queensland. The current feral goat populations in Australia repr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Banteng
The banteng (''Bos javanicus''; ), also known as tembadau, is a species of wild Bovinae, bovine found in Southeast Asia. The head-and-body length is between . Wild banteng are typically larger and heavier than their Bali cattle, domesticated counterparts, but are otherwise similar in appearance. The banteng shows extensive sexual dimorphism; adult bulls are generally dark brown to black, larger and more sturdily built than adult cows, which are thinner and usually pale brown or chestnut red. There is a big white patch on the Rump (animal), rump. Horn (anatomy), Horns are present on both sexes, and are typically long. Three subspecies are generally recognised. Banteng are Cathemerality, active during the day as well as at night, though Nocturnality, activity at night is more in areas frequented by humans. Herds comprise two to forty individuals, and generally a single bull. Being herbivorous, banteng feed on vegetation such as grasses, sedges, Shoot (botany), shoots, leaves, ...

Brumby
A brumby is a free-roaming feral horse in Australia. Although found in many areas around the country, the best-known brumbies are found in the Australian Alps region. Today, most of them are found in the Northern Territory, with the second largest population in Queensland. A group of brumbies is known as a "mob" or "band". Brumbies are the descendants of escaped or lost horses, dating back in some cases to those belonging to the early European settlers. Today they live in many places, including some National Parks, notably Alpine National Park in Victoria (Australia), Victoria, Barrington Tops National Park and Kosciuszko National Park in New South Wales, NSW, and Carnarvon National Park in Queensland. Occasionally they are Muster (livestock), mustered and tamed for use as Campdrafting, campdrafters, working stock horses on farms or Station (Australian agriculture), stations, but also as trail riding, trail horses, horse show, show horses, Pony Club mounts and pleasure horses. ...
