Effective population size (Ne) estimates determined using the linkage disequilibrium method with a minimum allele frequency of 0.02. (a) Point estimates for 2001 (N = 33) and 2013 (N = 258). Error bars indicate 95% confidence intervals estimated by jackknife estimates, where those running off the chart include infinity. Red dots represent point estimates. (b) Lower bound values of the confidence intervals for 2001 (N = 30) [the reduction from 33 to 30 is to allow resampling] and 2013 (N = 33) from 1000 re-sampled files. Red dots represent harmonic means of all the point estimates based on 1000 replicates.
