  1. Biodiversity & Classification ofLife on Earth Biology

  2. Biodiversity: all different species on Earth

  3. More than animals on Earth

  4. Diversity on Earth • ~10 million species on Earth • ~2 million are known to science

  5. Identifying Unknown Species

  6. Search rainforests, oceans…

  7. 2009 species • Rat eating pitcher plant (Philippines) • Translucent Dracula minnow (Myanmar)

  14. 2016 species • Klingon Newt

  15. 2017 species • Skywalker Hoolock Gibbon (Hoolocktianxing)

  16. Taxonomist • Identifies and names organisms The Louisiana Pancake Batfish!

  17. Classification • Grouping species based upon similarities • Each species receives a Latin name DendrobatespumilioDendrobatesauratusDendrobatesazureus DendrobatesleucomelasDendrobatestinctorius

  18. Identifying Known Species

  19. You are now a field taxonomist • On your first day you see this bird! • What Joy!!! • Now what bird is this?

  20. Dichotomous Keys • An easy way to sort information • Uses a series of yes or no questions to get to a single description that applies to only one item

  21. Partial Dichotomous Key for Sparrows • 1a. Small bird with brown and gray feathers……………………………....…go to 2 • 1b. Small bird with dark gray and white feathers…….…………………… go to 5 • 2a. Bird with solid red cap…………………………………………………….…………..……..3 • 2b. Bird with white and black striped cap……………………………..…………………4 • 3a. Bird with one white stripe on above eye………………….chipping sparrow • 3b. Bird with gray chest……………………………………………..………….tree sparrow • 4a. Bird with yellow spot above eye…….……….………white-throated sparrow • 4b. Bird with no yellow spot above eye………………..white-crowned sparrow • 5a. Bird with pink bill……………. Dark-eyed Junco • 5b. Bird with white wings………………………go to 6

  22. White-crowned SparrowZonotrichialeucophrys

  23. Following a dichotomous key is similar to playing a game of GUESS WHO? • “is your person a boy?”

  24. Hints for Using D.K. • Always, Always, Always start at the beginning • Always read both choices • Be sure you understand the meaning of terms involved. • Do not guess. • When measurements are given, use a calibrated scale. • Do not guess. • Do not accept your answer as absolutely reliable. Check a description of the organism to see if it agrees with the unknown specimen.
