  2. 2. 16.4 Threats To Biodiversity Warm-Up 16.4 B • Write 2 open-ended questions & 2 closed ended.
  3. 3. 16.4 Threats To Biodiversity Warm-Up 16.4 C • Write 2 open-ended questions & 2 closed ended.
  4. 4. 16.4 Threats To Biodiversity KEY CONCEPT The impact of a growing human population threatens biodiversity.
  5. 5. 16.4 Threats To Biodiversity Preserving biodiversity is important to the future of the biosphere. • The loss of biodiversity has long-term effects. – loss of medical and technological advances – extinction of species – loss of ecosystem stability
  6. 6. 16.4 Threats To Biodiversity Loss of habitat eliminates species. • Habitat fragmentation prevents an organism from accessing its entire home range. – occurs when a barrier forms within the habitat – often caused by human development
  7. 7. 16.4 Threats To Biodiversity • Koala bear habitat fragmentation
  8. 8. 16.4 Threats To Biodiversity • Habitat corridors are a solution to the problem. – corridors can be road overpasses or underpasses – allow species to move between different areas of habitat King Koala
  9. 9. 16.4 Threats To Biodiversity Introduced species can disrupt stable relationships in an ecosystem. • An introduced species is one that is brought to an ecosystem by humans. – accidental – purposeful • Invasive species can have an environmental and economic impact.
  10. 10. 16.4 Threats To Biodiversity • Invasive species often push out native species. – Burmese python (Florida Everglades)
  11. 11. 16.4 Threats To Biodiversity • Invasive species often push out native species. – mice (Australia)
  12. 12. 16.4 Threats To Biodiversity • Invasive species often push out native species. – kudzu (southeastern United States)
  13. 13. 16.4 Threats To Biodiversity HW: 16.5 5 Facts/Page • Study Guide 16.4 1. What is biodiversity? 2. Why is it important to preserve biodiversity? 3. Where are the highest levels of biodiversity on our planet? Why is this so? 4. List three ways in which humans cause habitat fragmentation. 5. What is an introduced species? 6. What is the impact on the ecosystem of a Burmese python. 7. What is the impact of mice in Australia? Quiz is next
