Ratio of the dugong abundance estimates using the availability detection probabilities from: 1) Pollock et al. [18] and 2) this study and the corresponding coefficients of variation (CV) of the abundance estimates.

^aAbundance estimate from this study (numerator)/ corresponding estimate from Pollock et al. (2006) (denominator).
