The means and routes by which invasive species are imported or introduced into new environments are called pathways, or vectors. Globalization has increased long-distance travel and commerce. This and other factors have increased the frequency of introductions of nonnative plants, animals and pathogens to aquatic and terrestrial ecosystems around the globe. Natural pathways (i.e., those not aided by humans), such as marine debris, can also bring harmful species to a new habitat. The ‘harm’ may in fact be outcompeting, and wiping out, native species in areas the newcomer colonizes.
