The prey of a natural predator has evolved along side the predator so has developed ways to cope, such as being able to climb a tree.
Now let's say you intoduce a predator that can also climb a tree... the prey doesn't stand a chance. Another reason is that, for thousands of years, certain species have eaten certain foods. Another larger or more voracious, species, or even one that breeds much more quickly, can wipe out the native animals' food sources. This is why the rabbit, for example, is so destructive for Australian native wildlife.

∙ 12y agoSometimes the balance of nature is upset by introducing something into an environment away from it's natural predators, they breed like wildfire and take over. For example it has actually happened with sheep, goats and rabbits to a few countries that never had them before. You might say the rabbits bred like, well..rabbits.

Why are non-native species dangerous to ecosystems?
Sometimes a non-native species can be introduced into an environment as a way to address an environmental problem. Other times these are introduced by accident.
What are species that migrate or are accidentally introduced into an ecosystem called?
Non-native species
What is a new species that has been introduced to the US?
Most domesticated dogs are non-native, as are many vegetables and flowering plants.
What is the difference between a native species and an introduced species?
Native plants are plants that belong to an environment (they have evolved there). Exotic plants are plants that have been imported from elsewhere in the world and are not natural to the environment in which they are now living.
Introduced alien species?
In Victorian times, Japanese Knotweed was introduced into Britain as an ornamental garden plant. It has since escaped and spread and has now become a very persistent weed that is difficult to eradicate. Another example is when rabbits were introduced into Australian, and have since grown to such huge numbers, that they are now considered a pest. There are many examples world-wide of introduced species that have decimated the native species, even to the point of extinction.

How are native species and introduced species related?
Eventually, all native species had to have been introduced sometime. So, native species are introduced species that have been in the ecosystem for a long time, and it and the other organisms have adapted to each other.

What is the species that is not native to a ecosystem?
It's an introduced species such as rabbits being introduced into Australia.
Introduced species can have important effects on biological communities by?
Preying upon native species competing with native species for resources displacing native species :)
What is a native sheep to Australia?
Sheep are not native to Australia - they are an introduced species.
Are donkeys an introduced species of Australia?
Yes. Donkeys are introduced, and not native to Australia.
What are species that migrate or are accidentally introduced into an ecosystem called?
Non-native species
Why are the introduced species causing damage to Australian native animals?
In the first place, introduced species threaten the food supplies of native animals. Introduced species tend to breed more quickly than native species, so they eat more, often razing feeding grounds which would support native herbivores for months by eating vegetation right down to the roots. Secondly, many introduced species are predators, and native Australian animals have not developed effective defence adaptations against predators that are new to them. Introduced plant species tend to spread more quickly through native habitats, killing off native plant species which might provide the natural food of Australian animals.
Problems when a new species is introduced into an ecosystem?
A new species, when introduced to an ecosystem, will compete with the indigenous species for food and resources. If the new species is predatory, it may also begin preying on the indigenous species, so the native populations will decrease sharply.
How many species of frogs are there?
There are seven species of frog found in New Zealand, three of which are non-native species introduced by settlers. An additional five species were introduced in the 1800's that were unable to establish successful populations. None of these are present today. All of the native species and two of the introduced species are listed as threatened or endangered.
Is the panda species introduced or are they native?
That depends. What area are you talking about? In some areas, pandas are native and in other areas, pandas are introduced. It depends on the location of which you are asking. They are native to China.
Causes of extinction in New Zealand?
Introduced species and habitat loss are the primary causes of extinction of native species in New Zealand. Introduced species such as feral cats, foxes, rats and stoats have decimated some native populations. Even the brushtail possum, rainbow lorikeets, black swan and cockatoos which have been introduced from Australia, threaten the habitat of native New Zealand species.
