... The straight-line distance estimates are conservative, as sea turtles do not move in straight lines. Size estimates of the nesting populations were taken from: Bellini (1996), Bellini et al. (1996), Seminoff et al. (2002Seminoff et al. ( , 2015, and Formia et al. (2006). The analyses were carried out using about 7,500 iterations until Gelman and Rubin diagnostics confirmed convergence of the chains to the desired posterior density, with most shrink factors near 1.0 and below 1.2. ...

... Estudos com DNA mitocondrial (DNAmt) mostraram que as diversas populações de locais de desova podem ser distinguidas por diferentes haplótipos. Em áreas de alimentação há uma mistura de haplótipos, indicando que tartarugas de diferentes estoques genéticos (áreas de desova) coexistem em áreas de alimentação e em outras áreas distantes das de desova (Bass 1999, Lara-Ruiz et al. 2006 Corroborando com os resultados dos estudos genéticos, os dados de marcação realizados no Brasil mostram migrações de longa distância através de dois indivíduos subadultos marcados em Fernando de Noronha e no Atol das Rocas, recapturados no Gabão e no Senegal (África), respectivamente (Bellini et al. 2000, Grossman et al. 2007). ...

... low frequency of hawksbill strandings that we found (n = 8) was expected, as this species occurs less frequently in the southern and southeastern regions of Brazil and is more abundant throughout the northern-northeastern coast ). The primary nesting sites for Hawksbill Turtles are in northeastern Brazil, as well as two of the most important feeding grounds in the country: Fernando de Noronha Archipelago (Sanches and Bellini 1999) and Rocas Atoll (Marcovaldi et al. 1998). Seven Hawksbill Turtles that we found were neritic-stage juveniles, suggesting that the coast of Rio de Janeiro supports a small foraging aggregation; however, more work is needed to understand their foraging ecology and genetic origins. ...
