Presentation Transcript

  1. Nuts & Bolts of Biodiversity

  2. Time • 3 x 90 min sessions • Plus field work

  3. Classification – taxonomy, keys • Ecosystem services, migration, mitosis • Extinction, evolution, convergent & divergent evolution

  4. Materials & Methods • Iron fasteners – nuts, bolts, screws, cotter pins, washers • Like above, except brass, Al, nylon, stainless steel • 12 cm x 12 cm plywood sheet, drilled hole • 12 cm x 12 cm metal sheet, drilled hole • Magnets

  5. If running chromatography • Solvents for extraction • Running media

  6. Discuss features for classification • Discuss convergent evolution

  7. Exercise • Fasten the sheets

  8. Mix groups • Try fastening exercise

  9. Discuss • Ecosystem services • Migration • Symbiosis • Adaptation

  10. Redistribute hardware • Group A: Mix of all • Group B: Mix of all except no stainless steel nuts

  11. Pass magnet

  12. Return to attaching 2 plates

  13. Biodiversity loss • Loss of ecological services • Extinction

  14. Field Work • Backyard biodiversity • Collect leaves • Labeling • Classification • Check classification scheme against master list • Can be done with macroinvertebartes

  15. Molecular Taxonomy • Chlorophyll chromatography

  16. Discussion • Backyard biodiversity • Issues of classification/taxonomy – selection of features • Biodiversity & ecosystem services

  17. Feedback • Needed lecture on the hardware

  18. Biodiversity - dynamic • Seasonal changes • Diurnal changes

  19. Ties in with • Appearances Are Deceiving • Used extensively in Puerto Rico field trip • Worksheets 2 & 3

  20. Problems • Seasky website ???

  21. Thoughts • Assign an article or two on • Classification • Biodiversity (species, taxonomic, ecosystem, genetic)
