  1. Migration Advanced Biology – Spring 2013

  2. WARM UP • Why do animals migrate? • Do humans migrate? • List some differences and similarities between why each species below migrates.

  3. What is migration? • Migration:

  4. What is migration? • Migration: A regular (or in some rare cases irregular) movement over relatively long distances.

  5. What is migration? • Migration: A regular (or in some rare cases irregular) movement over relatively long distances. • Many types of animals migrate, a few examples:

  6. What is migration? • Migration: A regular (or in some rare cases irregular) movement over relatively long distances. • Many types of animals migrate, a few examples: • Birds • Fish • Mammals

  7. What is migration? • Migration: A regular (or in some rare cases irregular) movement over relatively long distances. • Many types of animals migrate, a few examples: • Birds • Fish • Mammals • Three techniques animals use to migrate.

  8. Migration Techniques

  9. Migration Techniques • PILOTING:

  10. Migration Techniques • PILOTING: • When an animals moves from one familiar landmark to another until it reaches its destination.

  11. Migration Techniques • PILOTING: • When an animals moves from one familiar landmark to another until it reaches its destination. • ORIENTATION:

  12. Migration Techniques • PILOTING: • When an animals moves from one familiar landmark to another until it reaches its destination. • ORIENTATION: • Animals can detect compass directions and travels in a particular straight line path for a certain distance or until it reaches its destination.

  13. Migration Techniques • PILOTING: • When an animals moves from one familiar landmark to another until it reaches its destination. • ORIENTATION: • Animals can detect compass directions and travels in a particular straight line path for a certain distance or until it reaches its destination. • NAVIGATION:

  14. Migration Techniques • PILOTING: • When an animals moves from one familiar landmark to another until it reaches its destination. • ORIENTATION: • Animals can detect compass directions and travels in a particular straight line path for a certain distance or until it reaches its destination. • NAVIGATION: • When one determines one’s present location relative to other locations, in addition to orientation.

  15. Types of Migration

  16. Types of Migration • Seasonal Migration:

  17. Types of Migration • Seasonal Migration: • Migration that corresponds with the changing of seasons. • Most migrations are seasonal migrations.

  18. Types of Migration • Seasonal Migration: • Migration that corresponds with the changing of seasons. • Most migrations are seasonal migrations. • Latitudinal Migration:

  19. Types of Migration • Seasonal Migration: • Migration that corresponds with the changing of seasons. • Most migrations are seasonal migrations. • Latitudinal Migration: • Movement of animals from North to South.

  20. Types of Migration • Seasonal Migration: • Migration that corresponds with the changing of seasons. • Most migrations are seasonal migrations. • Latitudinal Migration: • Movement of animals from North to South. • Altitudinal Migration:

  21. Types of Migration • Seasonal Migration: • Migration that corresponds with the changing of seasons. • Most migrations are seasonal migrations. • Latitudinal Migration: • Movement of animals from North to South. • Altitudinal Migration: • The movement of animals up and down land features, like mountains.

  22. Types of Migration

  23. Types of Migration • Reproduction Migration:

  24. Types of Migration • Reproduction Migration: • The migration of animals to bear young.

  25. Types of Migration • Reproduction Migration: • The migration of animals to bear young. • Removal Migration:

  26. Types of Migration • Reproduction Migration: • The migration of animals to bear young. • Removal Migration: • Migration of animals that don’t return to the original area.

  27. Types of Migration • Reproduction Migration: • The migration of animals to bear young. • Removal Migration: • Migration of animals that don’t return to the original area. • Complete Migration:

  28. Types of Migration • Reproduction Migration: • The migration of animals to bear young. • Removal Migration: • Migration of animals that don’t return to the original area. • Complete Migration: • When almost all members of the species leave their breeding range during the non-breeding season.

  29. Types of Migration • Reproduction Migration: • The migration of animals to bear young. • Removal Migration: • Migration of animals that don’t return to the original area. • Complete Migration: • When almost all members of the species leave their breeding range during the non-breeding season. • Partial Migration:

  30. Types of Migration • Reproduction Migration: • The migration of animals to bear young. • Removal Migration: • Migration of animals that don’t return to the original area. • Complete Migration: • When almost all members of the species leave their breeding range during the non-breeding season. • Partial Migration: • When some, but not all, of the species leave their breeding range during the non-breeding season.
