Nest site selection and hatching success of hawksbill and loggerhead sea turtles (Testudines, Cheloniidae) at Arembepe Beach, northeastern Brazil

摘要: Nest site selection and hatching success of hawksbill loggerhead sea turtles (Testudines, Cheloniidae) at Arembepe Beach, northeastern Brazil. influences the represents a crucial aspect their reproductive process. in State Bahia, Brazil, is known nest for Caretta caretta Eretmochelys imbricata. For nesting seasons 2004/2005 2005/2006, we analyzed influence beach profile amount vegetation cover on both species. Loggerhead nested preferentially sand zone, while demonstrated no preferences either or zone. Beach was important modulation behavior species, but influenced (negatively) only hawksbill, mainly via increment non-hatched eggs. Hatching success, outside tide risk not by position nests along profile. The pattern distribution species indicated that management inundation erosion more than turtles. an factor conservation these turtle Nests are due to tidal can be translocated any without producing significant effect as long high densities avoided nests. It point out report here could part pure hybrid individuals, since there reports hybridization among hawksbills loggerheads study site.
