How did Terry Irwin estimate the number of Tropical Arthropods?
1. Fogged one tree in Panama
2. Found 1,200 beetle species, 163 are host specific
3. There are 50,000 tropical tree species
4. There are 8,000,000 beetles
Since beetles are 40% of arthropods, it totals 20,000,000
5. There are 10,000,000 ground-dwelling beetles
6. There must be 30,000,000 Tropical Arthropods!
