The Impact of Invasive Species on Ecosystems

The impact on ecosystems ranges from artificial causes such as bulldozers to natural causes such as fire and floods. Recently, the introduction and diffusion of invasive species has rapidly changed the indigenous community and, in some cases, irreversible damage. In the history of the earth, the ecosystem often changes. For example, the retreat of glaciers and glaciers caused widespread change. However, while ecological changes are constant, animals and habitats often do not adapt to the sudden changes in unnatural stress.

Invasive species pose a serious threat to biodiversity (IUCN, 2000). Millennium Ecosystem Assessment (2005) noted that the impact of invasive species on tropical ecosystems is rapidly rising. Likewise, recognizing the increased impact of invading species, the Convention on Biological Diversity provides the Parties "to prevent invasion, management or eradication of intrusive species that threaten ecosystems, habitats and species" Article 8 h). This systematic review attempts to summarize, evaluate and communicate the results of existing research to address the effects of invading plants on tropical biodiversity. The agreement will provide an a priori guide and will allow the scientific community to comment on the method and other related issues. Various studies on the influence of invasive plant species on tropical biodiversity

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.

Invasive species have the ability to change the entire ecosystem. Invasive species are not the original animals and plants of the ecosystem, but when introduced there, invading species do something injury to the life of animals in other plants and ecosystems. This occurred in the 1988 zebra mussel of St. Clair ecology. Zebra mussel passes through lakes, rivers and canals immediately. They need to enter nearby power plants and water supply systems, block pipes and drains, and be repaired. In addition, due to the bad influence of zebra mussels, there are few aborigines of the lake.
