  2. Black rat

  3. Starling

  4. Invasive Speciesalso known as exotic species, bioinvaders • Plants, animals & microbes not native to region • Accidentally or intentionally introduced • Out-compete native species for resources • Reproduce prolifically • Difficult to control due to lack of native predators • Dominate ecosystems

  5. Zebra Mussel (24 MM)

  6. Caspian Sea to Missouri River????HOW????

  7. Just a Long Ride Across the Ocean in a Big Ship • 1988 – Lake St. Clair (connects Lake Huron & Lake Erie • 1990 – in all Great Lakes • 1991 – into Illinois & Hudson Rivers • 1992 – Arkansas, Cumberland, Hudson, Illinois, Mississippi, Ohio & Tennessee • 1994 – 19 states report zebra mussels • 2002 – isolated quarry in Virginia

  16. Field of purple loosestrife

  17. Chestnut Blight Fungus

  18. Brown Tree Snake

  19. Impacts of Invasive Species Decrease in local/global biodiversity --> decrease ecosystem health --> extinction • competition • change to habitat • domination of habitat • changes in predator/prey relationships • carry disease • hybridization

  20. Am I an invasive species to the Galapagos Islands?

  21. Effects Cont. • Estimated U.S. cost - $125-140 billion annually • Estimate: 25% U.S. agriculture gross national product lost to foreign pests • Nearly half of the species listed as threatened or endangered under the Endangered Species Act are at risk due to competition with or predation by invasive species

  22. What can you do to help solve this problem?
