  1. Aliens Among Us Invasive Species and Their Influence On Our World A lesson from the Mathematics & Science Center

  2. Aliens Among Us Good Alien……… ………Bad Alien Just like in “Men in Black” Mathematics & Science Center

  3. Some aliens add beauty to the world… Courtesy Chesapeake Bay Program Mute Swan Cygnus olar Mathematics & Science Center

  4. Some aliens add beauty to the world… But they may create many problems for their habitat. Courtesy Chesapeake Bay Program Mute Swan Cygnus olar Mathematics & Science Center

  5. Some aliens add beauty to the world… But they may create many problems for their habitat. These swans feed on beds of submerged aquatic vegetation (SAV’s), which are vital to the ecosystem of the Chesapeake Bay.

  6. Some aliens do not cause many problems or are worth any trouble they may cause: “Eat More Chicken” Kansas Assoc. of Wheat Growers www.wheatonline.com Photo courtesy www.usda.gov NO WAY! Chris Vogel Mathematics & Science Center

  7. One of the more invasive of the invasive species, and one that has received lots of publicity is the Zebra Mussel Dreissena polymorpha Mathematics & Science Center

  8. They first appeared in the U.S. in the Great Lakes and have since moved into many other waterways. Mathematics & Science Center

  21. 2. Their fast rate of reproduction Notice the baby zebras attached to the adults David DennisCollege of Biological Sciences, Ohio State University 3. Easily transported by careless boaters Ladd JohnsonNOAA/Great Lakes Environmental Research Laboratory Mathematics & Science Center

  22. 4. Harms other organisms Fred Synder, Ohio Sea Grant Clam and Crayfish covered with Zebras Ontario Ministry of Natural ResourcesGLSGN Exotic Species Library Mathematics & Science Center

  23. How Do Aliens Get Here? By Land By Sea By Air Or….. the number one answer is: People Mathematics & Science Center

  24. How Do Aliens Get Here? Many of our aquatic aliens arrive in ballast water Courtesy MSC Mathematics & Science Center

  27. Can you identify an alien by looking at it? Martha Vogel Martha Vogel NO! Courtesy MSC Mathematics & Science Center

  28. Can you tell whether an alien is good or bad just by looking at it? NO! Courtesy Chesapeake Bay Program Mathematics & Science Center

  29. Research it: 1. The biology of the organism 2. The native habitat 3. The method of reproduction 4. Its natural enemies Mathematics & Science Center

  30. Signs that an alien might be an invasive: • Fast growing and rapid maturity • High reproductive rate – produces lots of seeds or offspring • Can out-compete native species • No natural controls • Is harmful to other organisms Mathematics & Science Center

  31. End of Section One Now you will work together to research an alien. Mathematics & Science Center
