INTRODUCED AND INVASIVE SPECIES 2012-2013 HOW DO WE REFER TO GROUPS OF ORGANISMS? Organism One individual living thing Population Group of organisms of the same species, that live in the same area Community Group of different species that live together in the same area NATIVE SPECIES those that evolved within the ecosystems where they are found. Natural controls to limit: Predators Parasites Resources INTRODUCED SPECIES species are those that are brought into an area, either on purpose or accidentally, by people. Can come from one continent to another Can be non-invasive or invasive INVASIVE SPECIES a species that has moved into an area and reproduced so aggressively that it has replaced some of the original species. Definitely do not belong in ecosystem http://www.youtube.com/watch?v=V5513w1XSk COMMON CHARACTARISTICS Ability to reproduce sexually and asexually Fast growth Rapid reproduction High dispersal ability tolerance of wide environmental ranges KUDZU Pueraria lubata Introduced in southern U.S. Can grow up to one foot a day http://www.youtube.com/watch?v=iLH1qLCvqS g ZEBRA MUSSELS Dreissena polymorpha Spread throughout the Great Lakes, U.S. waterways, and lakes EMERALD ASH BORER Agrilus Plannipennus Eastern United States Threatens to severely reduce or eliminate the ash lumber industry of U.S., with an estimated value of $25.1 billion per year http://www.youtube.com/watch?v=5d8evAfRw 2o
