  3. SPECIATION

  4. GENETIC DRIFT

  5. NATURAL SELECTION

  6. To Summarize:

  7. Loss of Diversity • Identify as many specific factors that lead to a loss of biodiversity. • Put this into a 30 second “infomercial” that will include everyone’s voice in the group.

  8. Loss of Diversity • Natural Hazards • Habitat Destruction (Fragmentation / Loss) • Agriculture • Exotic Species Introduction • Pollution • Hunting, Collecting, Harvesting

  9. Tropical Rain Forests

  10. Tropical Rainforests • Why are they vulnerable ecosystems? • What are there contributions to biodiversity?

  11. Species: What are we dealing with? • How many species currently? - how are they organized? • Past and present Extinctions?

  12. Why do Species Become Extinct? • Numbers of… • Degree of Specialization • Distribution • Reproductive Potential • Behavior • Tropic Level

  13. Population Size Reduction in Population Size Numbers of Mature Individuals Geographic Range and degree of Fragmentation Quality of Habitat Area of Occupancy Probability of Extinction

  14. Why do we save species? Arguments for are related to: • Ethical considerations • Aesthetic considerations • Genetic Resource considerations • Commercial considerations • Life-Support/Ecosystem Support Functions

  15. Designing Protected Areas
