But the most destructive invasions are invariably those caused by human activity, whether deliberate or inadvertent. These are examples of species that were brought to the Americas intentionally by European colonists. Economic costs associated with exotic species include agricultural losses, damage to infrastructure, as when aquatic plants clog water intakes, and the costs of attempts to restore native species whose survival is endangered by introduced species . possibly to a degree possible of achievement or by possible means 2) Rattus rattus, a native of the Indian subcontinent, has now spread throughout the world. exotic species that have become established and are able to sustain their population even without human help) and “acclimatized species” (i.e. Eventually, through reproduction and continued variation, fish came about.

The introduction of exotic species in aquaculture: a solution or part of the problem? However, many nonnative species do enormous environmental damage. In its native northern Europe, resident beetles feed on its roots and leaves, keeping the loosestrife in check, so that it only appears occasionally and temporarily in disturbed sites. The Invasive Species Council is responsible for the development of a National Invasive Species Management Plan. If they are aggressive colonizers adapted to living in marginal habitat, introduced species can drive resident natives from their established sites and food sources, especially around the disturbed environments of human settlement. The sea was teeming with life. New York: Natural History Press, 1966.
