摘要: Abstract Bioko Island's southern beaches are important nesting sites for marine turtles in the Gulf of Guinea region. In this study, we present data on 4 species sea 5 (19 km) Island, from 2000 to 2014. A total 43,860 leatherback (Dermochelys coriacea), 16,778 green (Chelonia mydas), 1731 olive ridley (Lepidochelys olivacea), and 85 hawksbill turtle (Eretmochelys imbricata) encounters, defined as number tracks, were recorded Bioko's beaches. Since 2008, estimated females ranged 42 444, 63 649, 22 53 annually. This study presents first extensive tagging program where 790 tagged with Passive Integrated Transponder tags 2008 Only 6.1% returned nest again a remigration interval 3–4 yrs. addition, 279 flipper-tagged 2013–2014 nesti...
