  1. DO NOW! Describe the basic characteristics of an ALIEN…….

  2. Aliens? • Video • Video 1 • Video 2 • Video 3

  3. Aliens are…. • Not from this place • Potentially harmful • Might bring diseases • Might take over ecosystem • Unintentionally hostile • Use all the resources we have • Over populate

  4. What about these…

  5. Objectives: • Discuss Aliens • Define invasive species • Determine how invasive or exotic species are like ALIENS • Examine the damage to the ecosystem • Examine specific species • Project

  6. Invasive Species • An "invasive species" is defined as a species that is 1) non-native (or alien) to the ecosystem under consideration and 2) whose introduction causes or is likely to cause economic or environmental harm or harm to human health. • http://www.invasivespeciesinfo.gov/whatis.shtml

  7. Invasive species • Take over when introduced into a new ecosystem…. • WHY? Emerald Ash Borer

  8. Invasive species have no natural predator in the new ecosystem • They either eat the native species • OR they eat the native species food • Change ecosystems by altering food chain • Overpopulation due to no predators

  9. Effects • Can effect the environment ecologically or economically…. • What do I mean by ecological? • How about economical? • Ecologically they affect food webs and ecosystem structure. • Economically they affect profitable resources.

  10. Meet your local invasive species • Get your notebook and write down each organism as we review it. • This is part of your study guide. • You will be adding information later so leave room by each one. • PA invasive species
