Table 4. Mixed stock analysis results of 278 turtles from three foraging grounds along the Great Barrier Reef.
Results (mean% ± 95% confidence intervals in parentheses) from the Bayesian mixed stock analysis (MSA) (Pella & Masuda, 2001) for Cockle Bay, Green Island and Low Isles Green Turtles (both individually and by region). MSA was calculated using 25 regional breeding stocks as possible sources, but for simplicity only the four main contributors are listed—nGBR, northern Great Barrier Reef; sGBR, southern Great Barrier Reef; CS, Coral Sea and NC, New Caledonia. The combined contributions of the remaining 21 stocks are compiled into the ‘Other’ category. Model 1, uniform priors; Model 2, weighted priors.
