What are the negative impacts of an alien species on ecosystems?
Wiki User
∙ 9y ago
The presence of an alien species may lead to inter-specific competition. An alien species may reproduce quickly due to a lack of predators of the species's ability to utilize resources that native species cannot. The alien species may even introduce diseases. Predation by the alien species can lead to a loss of biodiversity and some native endangered species may be driven to extinction.

What positive and negative impacts do aliens species have on ecosystems?
One positive impact is that the alien species may be able to control a pest species in an ecosystem. It may also bring social and economical benefits such as the process of reforestation reducing soil erosion.However, the alien species may also have negative impacts on the ecosystem. It may lead to increased competition with native species, reducing the chances of survival for native organisms. Native species may be driven to extinction and this reduces biodiversity. The presence of an alien species may also upset the balance between predators and prey.
Why are some alien species a threat to ecosystems?
The two most common reasons non-indiginous species are threats to ecosystems are these:1) The new species takes resources, thus depriving indiginous species of those resources, and2) The new species upsets the predator / prey balance in the existing ecosystem.For example, if you were to introduce snakes in an area with no snakes, that could have the effect of depleting the population of rodents in that area, due to snakes' appetite for rodents. Because this is a new demand for rodents, you would be depriving birds of prey (for example) of the rodent food source, and you would be population INCREASE of those foodstuffs on which rodents feed. It is quite easy to see how this new species (snakes) could lead to further upsets in the ecosystem, both up and down the food-chain.

How do invasive species affect biodiversity area?
Alien and invasive species affect the biodiversity of a area because the species keeps spreading and soon it is everywhere. Then they change the amount of resources in a area. So the other plants die and and then the animals who eat those plants die too and so on. This is how a species can affect a whole forest or biodiversity.

Why do alien speecies often thrive in their new ecosystems?
When an alien species enters into a new environment it has no natural predators. Anything that could eventually become a predator would be standoff-ish at first since the alien represents something new and is thus feared. Once the new predators realize how to kill the alien species their population will deminish and eventually become under control.
