The Effects Of Foreign Species Introduction On An Ecosystem

Impact of introduction of alien species into ecosystems The impact of introducing alien species into ecosystems is extensive. From small microorganisms to large mammal species, many exotic species emerge everyday. The new meaning they introduce is often found. When alien species are introduced into the ecosystem, ecosystems usually do not contain new species of natural predators. The lack of predators sometimes leads to a combination of new species and a food supply that is exponentially suited to the species.

Introduction of non-native species in a region can damage the ecosystem and cause extinction of native species. This introduction can be called an alien species or invasive species. In some cases, invasive species compete with local species for food and feed on indigenous peoples. In other cases, a stable ecological balance may be affected by predation or other causes of unexpected species reduction. New species may also have diseases that are not resistant to native species.

Invasive species can have a variety of effects on native species, surrounding ecosystems and the economy. The greatest impact is competition and predation with other species. However, invasive species can affect other species through crossing and may change ecosystem services such as nutrient circulation and water filtration. Some of the economic consequences of invasive species are seen by agricultural production, reduced invasion and infection in forests, a reduction in tourism and recreational activities, and an increase in health threats due to new exotic diseases. One example is the West Nile virus. This causes human death and death of many birds, reptiles and other mammals.

A major problem threatening the integrity of today's natural ecosystems is the introduction of unintentional or unintentional nonconventional flora and fauna. By definition, these non-alien species or alien species evolve separately from the ecosystems they arrive so that conventional animals and plants are susceptible to competition, predation or parasites that new immigrants may bring. Because of geographical isolation, the island is particularly vulnerable to invasion of alien species, but in the era of this global material flow, the world is endangered by expanding world trade and international travel You may. When non-native species are introduced into the ecosystem, they can not be established or they can breed without surviving growing or even becoming a serious problem.
