“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

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.
