    1. Biogeography and the Geography of Extinctions Chapter 16

    2. The road to extinction Vulnerable ? Endangered ? Critically ? ? ?

    3. The road to extinction Vulnerable ? Endangered ? Critically ? ? ?

    4. The road to extinction Vulnerable ? Endangered ? Critically ? ? ?

    5. The road to extinction Vulnerable ? Endangered ? Critically ? ? ?

    6. The Linnaean shortfall number species ? vs. number species ?

    7. The Linnaean shortfall number species vs. taxonomists

    8. Centinelan extinctions species that go ? before being ?

    9. Human dominance and exploitation of Earth’s life support systems challenges to Earth’s biodiversity

    10. Can we use biogeography to recognize areas that are particularly important for sustaining Biodiversity?

    11. Geographic variation in Biodiversity some important general patterns: ? in species diversity towards ?

    12. Geographic variation in Biodiversity some important general patterns: Island effect (any isolated system): * Diversity ? with area * Diversity ? with isolation

    13. Geographic variation in Biodiversity some important general patterns: 3. Endemicity higher in ? and more ? regions

    14. Biodiversity Hotspots two perspectives: 1. geographic co-occurrence of many ?

    15. Biodiversity Hotspots two perspectives: 2. region with many local ?* * restricted area species

    16. Is the Distribution of Biodiversity Hotspots Predictable? 1. endemic bird areas parallel the ? gradient

    17. Is the Distribution of Biodiversity Hotspots Predictable? 2. endemic bird areas common on ?

    18. Do Biodiversity Hotspots overlap in different taxa? If they do, then protecting a region will protect many restricted-area species

    19. Do Biodiversity Hotspots overlap in different taxa? Central American birds, herps, and butterflies

    20. Do Biodiversity Hotspots overlap in different taxa? African birds, amphibians, mammals, plants

    21. fish

    22. lobsters

    23. The Geography of Extinctions

    24. The Geography of Extinctions

    25. The Geography of Extinctions

    26. The Geography of Extinctions

    27. Historical Extinctions vs. Current Threats Hunting, collecting, etc. Habitat destruction Introduced species Other causes

    28. Historical Extinctions vs. Current Threats Birds

    29. Mammals Historical Extinctions vs. Current Threats

    30. Mollusks Historical Extinctions vs. Current Threats

    31. Animals Historical Extinctions vs. Current Threats

    32. The Geography of Introduced Species native vs. introduced plants

    33. The Geography of Introduced Species native vs. introduced plants

    34. Hawaiian endemic vs. introduced

    35. New Zealand native vs. introduced

    36. Introduced species: Do they matter? effect of introduced ? on island ?

    37. Introduced species: Do they matter? effect of introduced ? on island ?

    38. Habitat loss and Habitat fragmentation Continuous and larger habitats Isolated and smaller habitats

    39. Habitat loss and Habitat fragmentation how much has been lost and fragmented? continental scale United States

    41. Habitat loss and Habitat fragmentation

    42. Habitat loss and Habitat fragmentation predicted changes: Stage 1. Initial ? of species restricted-range species most vulnerable

    43. Habitat loss and Habitat fragmentation predicted changes: Stage 2. Extirpation from ? big species go first

    44. Habitat loss and Habitat fragmentation predicted changes: Stage 3. Perils with ? genetic ? ? demographic ? ?

    45. Habitat loss and Habitat fragmentation predicted changes: Stage 4. Isolation local ? without colonization

    46. Biogeography of Global Climate Change greenhouse gasses and average global temperature

    47. Biogeography of Global Climate Change Range shifting

    48. Biogeography of Global Climate Change Extinction
