What is a non example of a species?

Answer 1

A non-native invasive species refers to any species that originates abroad but is introduced to a new territory, resulting in ecological, environmental and/or economic destruction. Often, the introduction of the invasive species is the result of human travel or transport which allows a species to "hitch a ride" to new areas they would not have otherwise visited. A perfect example in the US is the Zebra Mussel, a small mussel native to Eurasia. However, it is believed that the Zebra Mussel migrated to the United States in the ballast water of ships (which subsequently released them into US waterways). Since their introduction in the late 1980's, the Zebra Mussel has been responsible for clogging power plant water intake systems, blocking pipelines, changing water quality and threatening the existence of several species of native clams and mussels. (In their defense, they are also very effective at filtering pollutants out of the water which, in some areas, has increased the populations of native fish species.)
