  1. Variables for all populations were inferred via full likelihood pedigree analyses as implemented in COLONY. Averages for unaffected and oiled populations collected in 2010 and 2011 were derived from descriptive statistics in SPSS.
  2. No. parents = number of parents producing offspring inferred from offspring genotypes (effective number of breeders). Ne = Effective population size and its range as inferred from the sibship assignment method in COLONY. No. partners = average number of mates per individual. No. offpring/parent = average number of offspring a parent contributes to the trap sample. No. family clusters = number of groups with individuals linked by pedigree. % fullsibs and % halfsibs = percentage of total number of pairs being full sisters or half sisters. SD = standard deviation. For comparison among populations No. parents and No. family clusters were sample size corrected by extrapolating for the maximum sample size (n = 30).
