SUMMARY:Challenges and solutions in identifying the genes responsible for 
 local adaptation - Professor Michael Whitlock from Department of Zoology\,
  University of British Columbia\, Vancouver

DESCRIPTION:With the advent of increasingly accessible population genomic 
 information from a wider number of species\, “genome scans” to detect 
 the genetic basis of local adaptation have become more common. The genome 
 scans tend to look for unusually high among-population differentiation (FS
 T outlier approaches) or correlations between local allele frequency and a
  relevant environmental variable (Genome-Environment Associations\, GEA). 
 I will discuss some common challenges to genome scan approaches\, such as 
 the effect of recombination rate variation\, the difficulty of separating 
 local adaptation and ongoing global adaptation\, and subtle challenges cau
 sed by the details of population structure. I also present a new method of
  GEA\, called Weighted Z analysis or WZA\, which seems to outperform alter
 nate methods.
