INFLUÊNCIA DO CAMPO MAGNÉTICO NATURAL TERRESTRE NA MIGRAÇÃO DAS TARTARUGAS MARINHAS DA PRAIA DE INTERMARES, CABEDELO - PB

The Sea Turtles comprise seven species in the world, five of which are found in Brazil: Lepidochelys olivacea (Eschscholtz, 1829) (Olive Ridley Sea Turtle), Chelonia mydas (Linnaeus, 1758) (Green Turtle), Dermochelys coriacea (Vandelli, 1761) (Giant or Leatherback Turtle), Eretmochelys imbricata (Linnaeus, 1766) (Hawksbill Sea Turtle) and Caretta caretta (Linnaeus, 1758) (Loggerhead Sea Turtle). These marine species develop a life cycle that also involves egg spawning on urban beaches. The great efficiency of travel of these sea turtles is evident, since the distances traveled in the ocean are long. These animals are threatened with extinction and in the coast of Paraíba (Northeast Brazil) there is the NGO Guajirú that takes care of the preservation of these species. The NGO Guajirú's main goal is to monitor these individuals, estimating birth and mortality rates in the urban beaches of greater João Pessoa. In addition, the NGO does environmental education work with the local population. This study aimed to investigate the phenomenon of sea turtle migration, its causes and consequences, as well as the environmental problems that prevent these animals from completing their life cycle. Bibliographical researches were carried out, field visits were carried out, along a stretch of Intermares beach in search of nesting sites for Sea Turtles in the region. Photographic records were also made in the spawning areas. As results we can evaluate that although the magnetic field is a very accurate source of information for the orientation of these species and the birth rate is high for them, few individuals return to the beach, since most of them are victims of environmental problems such as pollution, urbanization or natural factors.
