  1. Estimates of andromorph frequency (Afreq), operational sex ratio (OSR) and male density (Mdens) per population and province (Ontario, Quebec and British Columbia), averaged across three study years (mean ± 1SE). An extended table with detailed information on sample sizes per population and per year is given in (Additional file 1).
