Item HOPPER DREDGING(2015) GOLDBERG, D.W; ALMEIDA, D.T; TOGNIN, F.; LOPEZ, G.G; PIZETTA, G.T; JUNIOR, N.O.L; SFORZA, R.Item Hopper Dredging Impacts on Sea Turtles on the Northern Coast of Rio de Janeiro State, Brazil(2015) GOLDBERG, D. W.; ALMEIDA, D. T.; TOGNIN, F.; LOPEZ, G. G.; PIZETTA, G. T.; LEITE JUNIOR, N. O.; SFORZA, R.Item Hopper Dredging Impacts on Sea Turtles on the Northern Coast of Rio de Janeiro State, Brazil(2015) GOLDBERG, D.W.; ALMEIDA, D.T.; TOGNIN, F.; LOPEZ, G.G.; PIZETTA, G.T.; JUNIOR, N.O.L.; SFORZA, R.The northern coast of the state of Rio de Janeiro, eastern Brazil, isan important nesting ground for loggerhead turtles (Caretta caretta),with about 1500 nests laid annually (Lima et al. 2012). It also hosts foraging grounds for juvenile green turtles (Chelonia mydas) and serves as a migration corridor (and possibly provides foraging habitat) for olive ridley turtles (Lepidochelys olivacea) (Reis et al. 2010; TAMAR - Brazilian Sea Turtle Conservation Program database, unpublished data) and leatherback (Dermochelys coriacea) turtles (López-Mendilaharsu et al. 2009).Item Olive ridley inter-nesting and post-nesting movements along the Brazilian coast and Atlantic Ocean(2019) SANTOS, E.A.P; SILVA, A.C.C.D; SFORZA, R.; OLIVEIRA, F.L.C; WEBER, M.I.; CASTILHOS, J.C; LÓPEZ-MENDILAHARSU, M.; MARCOVALDI, M.A.A.G.; RAMOS, R.M.A; DIMATTEO, AItem Olive ridley inter-nesting and post-nesting movements along the Brazilian coast and Atlantic Ocean. Endangered Species Research(2019-11-14) SANTOS, E.A.P.; SILVA, A.C.C.D.; SFORZA, R.; OLIVEIRA, F.L.C.; WEBER, M.I.; CASTILHOS, J.C.; LÓPEZ-MENDILAHARSU, M.; MARCOVALDI, M.A.A.G.; RAMOS, R.M.A.; DIMATTEO, A.The states of Sergipe and Bahia comprise the main nesting beaches for olive ridley sea turtles Lepidochelys olivacea in Brazil. Between February 2014 and March 2015, 40 L. olivacea were equipped with Argos platform transmitter terminal tags. A state-space model was applied to Argos location data to investigate the animals’ spatial ecology and identify areas of restricted movements (ARMs) and directional movements. The inter-nesting ARMs included the continental shelf from the south of Alagoas state to the north of Bahia, totaling 7244 km2 (kernel density estimation, 90% isopleth) and generally extended up to 22 km from the coast or to the 50 m isobath. The post-nesting directional movements were classified as either (1) neritic north/ northeastern (N/NE) Brazil to French Guiana (n = 4 turtles), (2) neritic south/southeastern (S/SE) Brazil (n = 16), or (3) oceanic (n = 19) from Brazil to West Africa. ARMs consistent with foraging areas were identified for 24 olive ridleys: 15 along the continental shelf of SE Brazil, 2 adjacent to Ceará and Maranhão states (between the 25 and 75 m isobaths), and 7 off the African countries of Cape Verde, Senegal, Gambia, Guinea-Bissau, and Sierra Leone. The results de monstrated the complexity of olive ridley movements from northern Brazil, raised questions about connectivity, and highlighted threats such as fisheries, ports, and hydrocarbon exploration fields overlapping with, or near to, high-use areas. These results can be used as a basis for spatial management measures to protect this endangered species.- SITAMAR:CONNECTING SEA TURTLES INFORMATION TO REACH BETTER CONSERVATION ACTIONS IN BRAZIL(2015-10-20) SANTOS, A.
