Introduced species

An introduced species (also known as an exotic species) is an organism that is not native to the place or area where it is considered introduced and instead has been accidentally or deliberately transported to the new location by human activity.

Perhaps the most common motivation for introducing a species into a new place is that of economic gain.

National Geographic (Mar. 15, 2012) Florida's warm weather and lush landscape offer an attractive habitat to a number of invasive species that are wreaking havoc on local ecosystems. Wild Chronicles investigates how these non-native species, including green iguanas, lionfish and a plant called hydrilla, first arrived. Conservationists suggest the ultimate culprits may be humans who release exotic species into an environment not prepared for their presence.

Ecuador: The Galapagos Island Under Threat From Climate Change

Deutsche Welle (Oct. 7, 2013) Ecuador's Galapagos Islands are a Unesco World Heritage site and home to flora and fauna found nowhere else in the world. But one in five native plants as well as nearly 50 percent of its endemic wildlife are under threat from climate change. Rising ocean temperatures are making it harder for species such as the famous Galapagos penguin and the giant tortoise to survive. Scientists with the Charles Darwin Foundation are doing what they can to protect these species from the effects of climate change. A number of changes to the energy sector - such as the introduction of clean electricity - are helping. The island of Floreana has already switched completely to electricity produced by jatropha seeds, which grow in the Manabi region in mainland Ecuador. Jatropha production is also bringing an economic upswing to farmers.
