Nuts & Bolts of Biodiversity

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

7. Discuss features for classification • Discuss convergent evolution

8. Exercise • Fasten the sheets

9. Mix groups • Try fastening exercise

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

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

12. Pass magnet

13. Return to attaching 2 plates

14. Biodiversity loss • Loss of ecological services • Extinction

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

16. Molecular Taxonomy • Chlorophyll chromatography

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

18. Feedback • Needed lecture on the hardware

19. Biodiversity - dynamic • Seasonal changes • Diurnal changes

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

21. Problems • Seasky website ???

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