  1. Ecology Interactions Unit Competition

  2. Remember! • Working together, and helping everyone to reach their full potential will benefit everyone in this class. We are all interconnected.

  3. Keep an eye out for “The-Owl” and raise your hand as soon as you see him. He will be hiding somewhere in the slideshow “Hoot, Hoot” “Good Luck!”

  4. Keep an eye out for “The-Owl” and raise your hand as soon as you see him. He will be hiding somewhere in the slideshow “Hoot, Hoot” “Good Luck!”

  5. Area of Focus: Competition.

  6. What is competition?

  7. Define the word competition as it might be related to the field of ecology.

  8. Competition: The interaction between organisms or species, in which the fitness of one is lowered by the presence of another.

  9. Competition: The interaction between organisms or species, in which the fitness of one is lowered by the presence of another. Fitness:

  10. Competition: The interaction between organisms or species, in which the fitness of one is lowered by the presence of another. Fitness: Good health.

  11. Four types of competition • - • - • - • - • -

  12. Interspecific competition: Over resources between different species.

  13. Interspecific competition: Over resources between different species.

  14. Intraspecific competition: The same species compete for resources.

  15. Intraspecific competition: The same species compete for resources.

  16. Activity! A little interspecific competition. • Note – This is different as we are not competing over resources. More fun however. • Visit http://www.mathsisfun.com/games/connect4.html

  17. Activity! Try and build the tallest Domino tower possible with the amount given. • I will visit each group to help / see how you are doing /

  18. Activity! Try and build the tallest Domino tower possible with the amount given. • I will visit each group to help / see how you are doing / interfere and disrupt the construction without you knowing that I am interfering.

  19. Interference competition: fighting / disrupting.

  20. Interference competition: fighting / disrupting.

  21. Birds will often chase other birds away from habitat.

  22. Fish will also protect their territory and chase away other fish.

  23. Exploitative: Share resources.

  24. Exploitative: Share resources.

  25. In a pack of wolves, there is a strict hierarchy of who feeds first.

  26. In a pack of wolves, there is a strict hierarchy of who feeds first. • First the alpha male or female will eat.

  27. In a pack of wolves, there is a strict hierarchy of who feeds first. • First the alpha male or female will eat. • Then the other wolves of the group.

  28. In a pack of wolves, there is a strict hierarchy of who feeds first. • First the alpha male or female will eat. • Then the other wolves of the group. • Each wolf has to respect it’s position in ranking, if not they will be corrected by the wolves that are higher in ranking.

  29. Theory • Competitive Exclusion: One thrives, the other goes extinct. • No two species with the same job can coexist.

  30. Competitive exclusion theory: All organisms exist in competition for available resources.

  31. Competitive exclusion theory: All organisms exist in competition for available resources. • Those that create a competitive advantage will flourish at the expense of the less competitive.

  32. Competitive exclusion theory: All organisms exist in competition for available resources. • Those that create a competitive advantage will flourish at the expense of the less competitive. • No two organisms can have the same niche.

  33. Competitive exclusion theory: All organisms exist in competition for available resources. • Those that create a competitive advantage will flourish at the expense of the less competitive. • No two organisms can have the same niche. • One species thrives,

  34. Competitive exclusion theory: All organisms exist in competition for available resources. • Those that create a competitive advantage will flourish at the expense of the less competitive. • No two organisms can have the same niche. • One species thrives, the other goes extinct.

  35. Paramecium Species A

  39. Paramecium species B population declines until extinction.
