This Wed Fe b 10 - 1038 Wickson (not computer lab this week) Finishing up Phylogeography (CH 7) Conservation Genetics – Ch 8 and paper Ouborg et al 2009 Cons. Genomics Homework #5 due 1pm Tuesday Feb 16 to Smartsite Monday Feb 15 - University Holiday – go play

Ouburg et al 2009 paper. An essay on the necessity and feasibility of conservation genomics What is the difference between the authors’ concepts of conservation genetics and conservation genomics? What are the basic models they present for each? What are they saying about adaptive and neutral variation and their importance for conservation of endangered species? What is their point about inbreeding depression? What arguments do they provide for why genomics is feasible for conservation efforts? Would you add anything to what they say? Do you disagree with any points? CH 8 – touch on each of the blue topics listed at beginning of chapter on page 247 (reminder to use that as guide for text reading.
