Figure 5.
Long-term demography of D. dugon investigated using coalescent Bayesian skyline plots shows recent rapid reduction of female effective population size in western Indo-Pacific populations. These plots show female effective population size (N e) of (a) all D. dugon individuals, (b) the eastern clades’ individuals and (c) the western clade individuals, based on an assumed rate of 7.0 × 10−9–7.5 × 10−8 substitutions/site/year. Time is given in thousands of years ago (kya). Colour bands indicate increasing (green) and decreasing (red) N e.
