Why most introduced species are not successful in there new environment?

Introduced species usually do well because native species have not developed the defenses required to protect themselves against the new type of threat that an introduced species presents. For example, the fox in Australia prevails so easily because so many of the small, native, ground-dwelling species are quite defenceless against the fox. Some can burrow, some can climb, but they cannot fight.
It is interesting to note that the echidna in Australia is one of the species least affected by introduced species. This is because it is highly adaptable to a variety of environments, cab burrow, and can protect itself by drawing itself into a tight ball with its spines sticking outwards. This sort of protection is rare among the Australian native animals.

Define what an introduced species is?
Non-native species that are superior competitors... Apex
Why a species is most likely to undergo adaptive radiation?
When there is a sudden and long lasting change in the environment, adaptive radation will occur.
What is a variation that can help an organism survive?
A "variation" is a genetic feature expressed in some physical, physio chemical or behavioral manner by a living organism that is not present in the general population of the species to which that living organism belongs. If that variation advantages that animal as compared to others of that species then the likelihood is that that animal will breed more successfully, potentially passing on that variation to its offspring. Slowly variations accumulate and one species changes into a new species - this is called evolution.
What environment has the most total bacteria?
The environment that has the most total bacteria are wet and warm environments. This is because these conditions are most favorable for growth and reproduction.
What are most species in today?
The planet, the atmosphere. Biologically, most species are in something called stasis. let you in on something this is serious
Which organism does the most damage to the envirement?
Domesticated farm animals, feral goats and introduced species do the most damage to the environment.
One reason why an introduced species might be very successful in a new environment?
Many nonnative (alien) species are able to survive in new environments due to environmental similarity such as temperature, rainfall, seasonality and habitats where food and water is in abundance or enough to survive on and also the presence of other same species individuals with whom reproduction is possible. Another reason why nonative species survive in nonnative habitats is because of the lack of its native predators to keep its numbers in check and therefore they survive and reproduce quickly and outcompete native species.
Why is Australia the ideal environment for platypuses?
Australia is ideal for the platypus because there are few natural predators. Apart from pythons, most predators of the platypus are introduced species.
What are Australian introduced species in the Murray?
There is no such thing as an Australian introduced species in the Murray River. If it is Australian, it is not introduced. Species which have been introduced from overseas include various species of Carp, Brown and Rainbow trout, Redfin perch and Gambusia. The most prolific of these is the carp.
What is the most destructive introduced species in the world?
Homo sapiens
What would most likely occur if a species is adapted to an environment then the environment changes quickly?
Most of said species die, if there is a favorable mutation existent in the population that characteristic will become more prevalent. If not the species will most likely go extinct.
What is North America's most abundant bird?

Why is the Kiwi the most endangered species in New Zealand?
It isn't. The kakapo, a large, flightless parrot, is the most endangered species in New Zealand. There are less than 100 of these birds remaining, as they are very vulnerable to predation by introduced species.

Why humans are considered to be a very successful species?
They are not, bacteria is the most important species - without them humans would not last more than a few hours.
Why do geckos live in rainforasts?
Not all gecko species come from rainforests. Most gecko species that do live in a rainforest is because the specific species thrives in a humid environment.
