One reason why an introduced species might be very successful in a new environment?

Why are bluebirds swallows wrens robins purple martins and re bellied woodpeckers now fighting for survival?

Some of these species are worse off than others but one a big reason is that much of their habitat is being destroyed.

What is the main reason that so many species are at risk?

They are being hunted or their environment is being changed.

Is a fox a quokka's predator?

Yes. The fox, an introduced species to Australia, is one of the main predators and threats to the quokka. The main reason why quokkas are not extinct is because they live on some offshore islands where foxes have not yet been introduced.

What is one reason there is more species diversity in the tropics?

there is more solar energy available in the tropics than in the temperate zones.

Are raccoons a omnivore?

Yes, they are fond of fish, corn, chickens, apples and any kind of organic matter, one reason why they have been so successful as a species.

Do bassethound and pitbulls get along?

Providing the two dogs have been well socialized and they are introduced in a neutral environment (local park etc.) there is no reason why these two breeds shouldn't get along.

What is an introduced species and how can such species affect native plants and animals?

Introduced species can either have a: positive effect, negative effect, or no effect at all. In most cases, introduced species will have no effect at all, and rarely a positive effect unless introduced for that exact reason. Ecologists usually use the "Tens Rule", which states that (on average) one out of every ten introduced species will become established; one out of every ten of those established species will become common enough to be pests. Following this rule, 90% of all introduced species will not become established in a new location for whatever reason. However, some species have a potential range that far exceeds their actual realized territory and thrive when translocated. For those that do become an invasive species, the effect on the native or indigenous species can be devastating. On almost all continents, there are invasive species that flourish in their new environment and drive competition to the max. Resources can be quickly used up and the competitive exclusion principle kicks in (two different species occupying the same geographical area cannot have the same ecological niche; one must evolve into a slightly different niche or face extinction). These invasive species are a great threat to biodiversity because they have the ability to wipe out entire species that are not prepared to cope with a new and abundant competitor. As mentioned earlier, introduced species can have a positive impact on the community. Usually these are introduced to an ecosystem in order to control another invasive species using the dynamics of trophic cascade (one trophic level suppresses another, the next level thrives, the next level is suppressed, etc). However, efforts to manipulate ecological problems hardly ever come to fruition, as 20 problems can arise from just one solution.

What is the main reason a puma is a endangered species?

Humans are the main reason that puma is endangered species. As a species, the puma is not an endangered species. Only the Florida race is endangered.

Why have sharks been alive for millions of years?

sharks have changed overtime. the reason species evolve is because they need to adapt to their environment. thts why there are different species of shsrks

Why does a species become a pest when introduced to a new land when it was not a pest in its country of origin?

Invasive SpeciesA pest is any living thing which has characteristics which people regard as injurious or unwanted. It is possible for something to be a pest in one setting but beneficial or domesticated in another. When millions of years of evolution in one sub-climate can enable itself to repair and overcome an indigenous species does not mean that it can be introduced into another sub-climate.Many species are introduced accidentally, but others are intentionally moved. An example of this is the cane toad, which was introduced into northern Australia in 1935 as an attempt at biological control. In tests where the toads were offered no food except the beetles that were destroying sugar cane crops, they ate them. When they found themselves in the cane fields with far more palatable food at hand - surprise, surprise. They ate that.Toads bred wildly and swarmed out of control. There are millions of them in Australia now. They are pests because they compete with native species for food and places to live, their tadpoles are aggressive, and the toads themselves are toxic and kill carnivores that eat them.Other animals were introduced unintentionally, such as feral horses, cattle, camels, sheep, goats and pigs (escaped from farms and multiplied). These animals are extremely useful in their farms, but outside of them, are pest animals because they destroy the environment in their search for food.The main reason something becomes a pest when introduced to a new place is that it has no predators there. There's nothing that eats it, and so it reproduces exponentially (really, really fast). In its place of origin, there was something that preyed on it, keeping its population down.A species when introduced into a new environment or community may or may not become a pest. The introduced species may become a pest if is better adapted to the community than other organisms occupying its niche. It may also become a pest if it has no biological enemies or predators in its new community to control it's numbers.

One reason for the Egyptians successful farming ws their wise use of irrigation.

What is the reason that pandas were put on the endangered species list?

The usual reason for any species on the list is there are not enough adult members.
