Invasive species may be plants, animals, fungi, and microbes; some include native species that have invaded human habitats such as farms and landscapes. [5] Some broaden the term to include indigenous or "native" species that have colonized natural areas. [ 4 ]
The economic impacts of invasive species can be difficult to estimate especially when an invasive species does not affect economically important native species. This is partly because of the difficulty in determining the non-use value of native habitats damaged by invasive species and incomplete knowledge of the effects of all of the invasive species present in the U.S. Estimates for the ...
The complete picture of long-term ecological effects from invasive pests is difficult to measure; and it is too early to determine the effects of the many new invasive pest introductions. Much of the research has focused of the biology of the pests—i.e. life cycle and host preferences—towards understanding how to contain their spread. [10]
In a meta-analysis of 19 research studies involving 72 pairs of native and invasive plants, invasive exotic species did not incur less damage than their native counterparts and, in fact, exhibited lower relative growth rates. [23] In other cases, invasive success was due not to release from herbivory but greater tolerance of it. [24]
Climate change is likely to favour some invasive species and harm others, [3] but few authors have identified specific consequences of climate change for invasive species. [4] As early as 1993, a climate/invasive species interaction was speculated for the alien tree species Maesopsis eminii that spread in the East Usambara mountain forests ...

Kudzu is an invasive plant species in the United States, introduced from Asia with devastating environmental consequences, [1] earning it the nickname "the vine that ate the South". It has been spreading rapidly in the Southern United States , "easily outpacing the use of herbicide, spraying, and mowing, as well increasing the costs of these ...
Invasive earthworms have caused a decrease in diversity, seedling populations, forest floor organic matter volume, and overall habitat quality. In addition, there is often an increase in invasive species and a decreased diversity of non-plant organisms. Some species that provide important biological niches to the ecosystem may be eradicated.
