Nuts & Bolts of Biodiversity
Time
• 3 x 90 min sessions
• Plus field work
• 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
If running chromatography
• Solvents for extraction
• Running media
Group A Group B Group C Group D
NO screws or bolts
No nuts Bolts Bolts
Nuts
Washers
Cotter pins
Washers
Washers Screws
Bolts
Nuts – wrong sizes
Etc.
Washers
• Discuss features for classification
• Discuss convergent evolution
Exercise
• Fasten the sheets
• Mix groups
• Try fastening exercise
Discuss
• Ecosystem services
• Migration
• Symbiosis
• Adaptation
Redistribute hardware
• Group A: Mix of all
• Group B: Mix of all except no stainless steel nuts
• Pass magnet
• Return to attaching 2 plates
• Biodiversity loss
• Loss of ecological services
• Extinction
Field Work
• Backyard biodiversity– Collect leaves– Labeling
• Classification
• Check classification scheme against master list
• Can be done with macroinvertebartes
Molecular Taxonomy
• Chlorophyll chromatography
Discussion
• Backyard biodiversity– Issues of classification/taxonomy – selection
of features
• Biodiversity & ecosystem services
Feedback
• Needed lecture on the hardware
Biodiversity - dynamic
• Seasonal changes
• Diurnal changes
Ties in with
• Appearances Are Deceiving
• Used extensively in Puerto Rico field trip– Worksheets 2 & 3
Problems
• Seasky website ???
Thoughts
• Assign an article or two on – Classification– Biodiversity (species, taxonomic, ecosystem,
genetic)
