Abundance trend of East Antarctic Adélie penguins over the last 22,000 years. Extended Bayesian skyline plot showing the change in effective female population size (N ef ), with the black line indicating the median estimate and the colour block showing the 95 % highest posterior density interval. The grey line indicates the East Antarctic temperature anomaly (the difference from the average of the last 1000 years) as estimated from the EPICA Dome C ice core [25]
