  7. We estimated the current number of green turtles in the greater Caribbean as lying between 1.15 x 106 and 9.71 x 106 individuals with mean masses of 46 or 18 kg, respectively. These estimates are based on (1) the estimated number of nesting females in the Tortuguero population, (2) an assumed 1:1 sex ratio, (3) the estimated proportion of adults from length/age (von Bertalanffy) and length-to-mass models, and (4) the percent contributed from smaller rookeries (Suriname, Aves Island, Florida, and Mexico), assuming these populations have similar demographic relationships as the Tortuguero population.

  10. We estimated historical numbers of dugong using historical reports of the areal extent of migrating dugong herds within large bays in eastern Australia. Assuming a density of one dugong per 12.7 m2 (derived from an aerial photograph of a dugong herd in Moreton Bay published in 71), a migrating herd "half a mile wide and from three to four miles long" in Wide Bay in the 1870s (69) would have comprised some 357,000 individuals. Similarly, a herd three miles long and 300 yards wide as reported in Moreton Bay in July 1893 (70) would have comprised about 104,000 individuals. Further assuming that each of the ten large bays between Brisbane and the Torres Strait contained similarly sized herds, we can estimate that the population size for eastern Australia in the 19th century must have been between 1.0 x 106 and 3.6 x 106 dugongs.
