Table 2.
Isotopic niche area described by Standard Ellipse Area (SEAc) (‰), Bayesian SEAb and parameters; N = number of samples, TA = total area of the convex hull, CD = mean centroid distance and standard deviation (SD), E = eccentricity, θ = angle of ellipse and CI = confidence interval. F = Females, M = Males, QLD = Queensland Shark Control Program and GBR, GBR = Great Barrier Reef and NSW = New South Wales.
