Biodiversity Exercise-Nemo

  1. 1. Dr. Mark A. McGinley Texas Tech University BIOL 5311 Summer 2011 Biodiversity Exercise- Nemo
  2. 2. What is “biodiversity” <ul><li>Biodiversity: </li></ul><ul><ul><li>the variety of life on Earth at all its levels, from genes to ecosystems, and the ecological and evolutionary processes that sustain it </li></ul></ul>
  3. 3. Diversity <ul><li>Diversity is a measure of how much variation there is. </li></ul>
  4. 4. Coral reefs are some of the most diverse communities in the world.
  5. 5. Biodiversity Game <ul><li>We are going to study coral reefs around some tropical islands to learn about biodiversity. </li></ul>
  6. 6. First Example Hawaii Tahiti
  7. 7. Tahiti
  8. 8. What do you notice about the reef in Tahiti? <ul><li>How many total fish are there? </li></ul><ul><li>How many different types of fish are there? </li></ul><ul><li>Draw a frequency distribution histogram </li></ul>
  9. 9. Graph- frequency distribution Number of individuals Species
  10. 10. What does this graph tell us? <ul><li>There is only one species on the reef and there are 5 individuals of that species living there. </li></ul>
  11. 11. Hawaii
  12. 12. What do you notice about the reef in Hawaii? <ul><li>How many total fish are there? </li></ul><ul><li>How many different types of fish are there? </li></ul><ul><li>Draw a frequency distribution histogram </li></ul>
  13. 13. Frequency Distribution Number of individuals Species
  14. 14. What does this graph tell us? <ul><li>There is only one species on the reef and there are 3 individuals of that species living there. </li></ul>
  15. 15. Which reef is more diverse? Tahiti Hawaii
  16. 16. Which Reef is More Diverse? Tahiti Hawaii Number of individuals Species
  17. 17. Which reef is more diverse? <ul><li>Although there are more fish in Tahiti than in Hawaii, there is only one kind of fish in each of the reefs </li></ul><ul><li>Because there is no variation at all in the types of fish found on the two reefs there is no difference in diversity between Tahiti and Hawaii </li></ul>
  18. 18. Second Example
  19. 19. Hawaii
  20. 20. What do you notice about the reef in Hawaii? <ul><li>How many total fish are there? </li></ul><ul><li>How many different types of fish are there? </li></ul><ul><li>Draw a frequency distribution histogram </li></ul>
  21. 21. Draw the frequency distribution Species Number of individuals
  22. 22. What does this graph tell us? <ul><li>There are five species on the reef and there is only one individual of each species living there. </li></ul>
  23. 23. Tahiti
  24. 24. What do you notice about the reef in Tahiti? <ul><li>How many total fish are there? </li></ul><ul><li>How many different types of fish are there? </li></ul><ul><li>Draw a frequency distribution histogram </li></ul>
  25. 25. Draw the frequency distribution Species Number of individuals
  26. 26. What does this graph tell us? <ul><li>There are 3 species on the reef and there is only one individual of each species living there. </li></ul>
  27. 27. Which reef is more diverse? Hawaii Tahiti
  28. 28. Which reef is more diverse? Hawaii Tahiti Number of individuals Species
  29. 29. Which reef is more diverse? <ul><li>Because there are more types of fish living in Hawaii than there were in Tahiti we would say that the community on the reef in Hawaii is more diverse. </li></ul>
  30. 30. Third Example
  31. 31. Hawaii
  32. 32. What do you notice about the reef in Hawaii? <ul><li>How many total fish are there? </li></ul><ul><li>How many different types of fish are there? </li></ul><ul><li>How many fish of each type are there? </li></ul>
  33. 33. Draw the Frequency Distribution Number of individuals Species
  34. 34. What does this graph tell us? <ul><li>There are 5 species on the reef. The most abundant species has 4 individuals, the second most abundant species has 3 individuals, the third most abundant species has 2 individuals and the two least abundant species each have one individual. </li></ul>
  35. 35. Tahiti
  36. 36. What do you notice about the reef in Tahiti? <ul><li>How many total fish are there? </li></ul><ul><li>How many different types of fish are there? </li></ul><ul><li>How many fish of each type are there? </li></ul>
  37. 37. Draw the Frequency Distribution Number of individuals Species
  38. 38. What does this graph tell us? <ul><li>There are 4 species on the reef. The most abundant species has four individuals, the second most individual species has three individuals, the third most abundant species has 2 individuals and the least abundant species has 1 individual. </li></ul>
  39. 39. Which reef is more diverse? Hawaii Tahiti
  40. 40. Which reef is more diverse? Species Number of individuals Hawaii Tahiti
  41. 41. Which reef is more diverse? <ul><li>Because there are 5 species in Hawaii and 4 species in Tahiti we would say that the reef in Hawaii is more diverse. </li></ul>
  42. 42. Species Richness <ul><li>Species richness measures the number of species that are found living in a community. </li></ul><ul><li>Communities that have higher species richness are more diverse. </li></ul>
