Pol is the ratio of polymorphic loci, and Ho is the gene diversity. The number of loci considered to estimate the gene diversity according to Linch and Milligan (34), is given between parenthesis. Ni is the number of individuals analysed and Nl is the total number of bands considered. The number of bands for each primer UBC (University of British Columbia, set #3) is given in parentheis.
