If an endangered species were introduced into a nonnative habitat they might flourish as there are no natural predators. Of course, it could make them dwindle even more if there wasn't any food.
Speciation is the best term to describe a new species developing from an existing one.
That species would have it's best chance of survival as a result of a mutation that has a high adaptive value that occurs in its gametes.
Inbreeding in any species weakens the genetic structure of the offspring and makes them weak and susceptible to infectious diseases. This can result in a comparatively weaker generation of species which may result in extinction too.

Biotic things are those things that live in an animal's habitat. They include plants and other animals, of all species. One species survival is a direct result of the biotic and abiotic factors in its environment.
An introduced species is a species that is living outside its native environment. This happens as a result of humans, either accidentally or on purpose. They can cause damage to the environment that they are introduced into. One example is the black rat being in North America even though it is from Europe.
introduced species
A:Cane toads are an introduced species that, in its native environment, is in harmony with nature. That it has become a disaster in Australia is solely the result of human stupidity in introducing a species without testing its potential impact on the environment. This has nothing to do with the supernatural.
When exotic species are introduced into a new ecosystem, they often don't encounter the same factors that controlled the exotic species population or growth that was in the original ecosystem.
Measles was introduced to the Native Americans with disastrous effects.
One example of a non-native invasive species is the Asian carp in North America. These fish have negatively impacted local ecosystems by outcompeting native species for resources and altering habitats. Their rapid breeding and ability to spread quickly have made them difficult to control.
In its natural range in the Americas, raccoons are natives and not an introduced or invasive species. As a result of escapes and deliberate introductions in the mid-20th century, raccoons are now also distributed across mainland Europe, Caucasia, and Japan where they might be considered as invasive.
Kangaroos are native to Australia.Tree kangaroos are native to both Australia and New Guinea.Various species of kangaroos, such as wallabies, have been introduced to countries such as New Zealand. The kangaroo is kept in captivity in other countries, such as the US and the UK.It should be noted that this captivity is not with the permission of the Australian government, but a result of prior illegal animal export activity.
Introduced species pose the biggest threat to the kowari. In particular, feral cats and foxes are their main predators. Native predators include quolls and owls. The kowari is also threatened by habitat loss and loss of food as a direct result of the introduction of rabbits and livestock, particularly feral goats.
A non-native invasive species refers to any species that originates abroad but is introduced to a new territory, resulting in ecological, environmental and/or economic destruction. Often, the introduction of the invasive species is the result of human travel or transport which allows a species to "hitch a ride" to new areas they would not have otherwise visited. A perfect example in the US is the Zebra Mussel, a small mussel native to Eurasia. However, it is believed that the Zebra Mussel migrated to the United States in the ballast water of ships (which subsequently released them into US waterways). Since their introduction in the late 1980's, the Zebra Mussel has been responsible for clogging power plant water intake systems, blocking pipelines, changing water quality and threatening the existence of several species of native clams and mussels. (In their defense, they are also very effective at filtering pollutants out of the water which, in some areas, has increased the populations of native fish species.)
Native species have natural enemies and do not usually cause a problem. Invasive species frequently do not have natural predators. As a result, Invasive species can create tremendous problems for people. For example: in Florida Water Hyacinths turned lakes into dead zones and breeding areas for mosquitoes. They have done the same in Africa. Africa does not need more mosquitoes spreading malaria. In the Great Lakes, the zebra mussel has choked off water inlets. For a while in the Great Lakes, lampreys killed the fish. In Alabama, an invasive plant threatens to destroy the timber industry. Thus, some invasive species have crowded out native species and made major changes in the ecology. As they crowd out the natural species they can bring plagues and pestilence with them. They can also cause the failure of modern machinery.
Most introduced (invasive) species are bad for existing communities because more times than not, they do not have natural predators. As a result, these species end up proliferating to a staggering degree and using up/consuming resources that other species in the community would be using. This throws off the balance of the system, decreases biodiversity, and wreaks general havoc.
