Transcript of “Indeed, some people would suggest that an intimate knowledge of how something works somehow...
“Indeed, some people would suggest that an intimate knowledge of how something works somehow diminishes its charm, relegating it to a simple deterministic consequence of a mechanical universe. But ignorance is not bliss . . .”
-- O.J. Reichman
What do biologists do about conservation and biodiversity?
• Catalog and track species
• Project future changes
• Document threats and study the processes behind them
• Examine the value of diversity
• Apply knowledge to restoration and management

Seed feeding
Gall makers or stem feeders
Shoot meristem feeders
Phylogenetic hypothesis (so far) based on variation in 836 bp of mtDNA (COI & II) and 967 bp of nuclear EF-1 using Bayesian analysis (MrBayes 3.1). Most taxa have multiple haplotypes (2-12) sequenced, but for simplicity are not shown here.
