And finally, species with high reproduction rate and low defense to natural enemies have a better chance of invading other areas.
Climate matching assesses the invasion risk and heavily prioritizes destination-specific action.
The brown tree snake was accidentally translocated by means of ship cargo to Guam, where it is responsible for replacing the majority of the native bird species.
[5] As an example, human led shoreline development, specifically in New England, was found to explain over 90% of intermarsh variation.
This human made change, among others, was the reason that Phragmites australis invaded the New England salt marshes.
This study specifically looked at how human habitat alteration led to the invasion success of this species.
Shoreline development, nutrient enrichment, and salinity reduction were all human made changes that contributed to the species ability to invade.
For example, the predictions of the identities and ecological impacts of invasive alien species assists in risk assessment.
Currently, scientists are lacking the universal and standardized metrics that are reliable enough to predict the likelihood and degree of impact of the specific invaders.
The addition, or removal, of a species from an ecosystem can cause drastic changes to environmental factors as well as the community's food web.
In the majority of cases, a small subset of introduced species become invaders as a result of rapid changes in the new habitat.
