| The identification of the inter-nesting habitat used by gravid sea turtles has become a crucial factor in their protection. Their aggregation in large groups of individuals during the inter-nesting period exposes them to increased threats to their survival - particularly along the French Guiana shield, where intense legal and illegal fisheries occur. Among the three sea turtle species nesting in French Guiana, the olive ridley appears to have the most generalist diet, showing strong behavioural plasticity according to the environment encountered. The large amounts of sediments that are continuously discharged by the Amazon River create a very unusual habitat for olive ridleys, i.e. turbid waters with low salinity. This study assesses the behavioural... |

| ABSTRACT Currently, plastics are recognized as a major pollutant of the marine environment, representing a serious threat to ocean wildlife. Here, we examined the occurrence and effects of plastic ingestion by sea turtles found stranded along the coast of Paraíba State, Brazil from August 2009 to July 2010. Ninety-eight digestive tracts were examined, with plastic found in 20 (20.4%). Sixty five percent (n = 13) of turtles with plastic in the digestive tract were green turtles (Chelonia mydas), 25% (n = 5) were hawksbills (Eretmochelys imbricata), and 10% (n = 2) were olive ridley (Lepidochelys olivacea). More plastic was found in the intestine (85%) than in other parts of the gastrointestinal tract. We observed complete blockage of the gastrointestinal... |

Relocations of Sea Turtle nests of Lepidochelys olivacea, Dermochelys coriace and Chelonia mydas in the Galibi Nature Reserve, Suriname. Studies Nat. Hist. Caribbean Region 73, Amsterdam, 1997: 63-69. Relocation of nests of the marine turtles Lepidochelys olivacea (ESCHSCHOLTZ 1829), Dermochelys coriace (LINNAEUS 1758) and CHELONIA MYDAS (LINNAEUS 1758) in the Galibi Nature Reserve is performed to protect them from a number of hazards. The hatching percentage per nest is not significantly decreased by relocation, but the number of nests from which hatchlings emerge is greatly enhanced. In this situation relocation can be an effective conservation measure. |
