Time

• 3 x 90 min sessions
• Plus field work

3

• Classification taxonomy, keys
• Ecosystem services, migration, mitosis
• Extinction, evolution, convergent divergent
  evolution

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

Washers
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)
