Item Case report: Ingestion of a massive amount of debris by a green turtle (Chelonia mydas) in Southern Brazil(2012) STAHELIN, G.D.; HENNEMANN, M.C.; CEGONI, C.T.; WANDERLINDE, J.; PAES E LIMA, E.; GOLDBERG, D.W.Marine debris is considered any solid waste (plastic, polystyrene, rubber, foam, glass, metal, cloth, and other man-made materials) that enters the marine or coastal environments from any source (Coe & Rogers 2000). The main sources of marine debris are litter carried into the sea from land-based sources in industrialized and highly populated areas and wastes from ships, fishing and recreational vessels (Derraik 2002). However, regardless of the source, marine debris can have serious ecological and economic consequences. These adverse impacts have been documented all over the world. According to Gregory & Ryan (1997), plastic pollution is estimated to represent between 60% and 80% of the total marine debris in the world's oceans. Within just a few decades since mass production of plastic products commenced in the 1950s, plastic debris has accumulated in terrestrial environments, in the open ocean, on shorelines and in the deep sea (Barnes et al. 2009). Every year, many species of marine animals, including sea turtles, marine mammals, seabirds and fish die from becoming entangled or ingesting plastic debris (Laist 1987). According to Carr (1987) sea turtles are particularly prone to eating plastics and other floating debris. Juvenile sea turtles are frequently exposed to pollution in convergence zones and most species are exposed in nearshore habitats, where they feed (Bjorndal et al. 1994). Evidence indicates that the high occurrence of non-food items in sea turtle species may be related to mistaken ingestion of plastics, due to its similarity to prey items (Plotkin et al. 1993), or even to incidental ingestion along with a prey (Tomás et al. 2002).- Enriquecimento ambiental para tartarugas marinhas em cativeiro no Museu Aberto do Projeto Tamar em Florianópolis(2013) GOLDBERG, D.W.; CEGONI, C.T.; STAHELIN, G.; WANDERLINDE, J.; GIFFONI, B.; LIMA, E.P.Bem-estar animal pode ser definido como um estado pleno de saúde física e mental, em que o individuo encontra-se em harmonia com o meio que o cerca. No ambiente natural, o animal enfrenta inúmeros fatores bióticos e abióticos que exigem amplo repertório comportamental, permitindo-o reagir às condições impostas em qualquer momento. Por outro lado, o ambiente reproduzido em cativeiro é limitado em vários aspectos e a transferência do animal de seu habitat natural para um ambiente de confinamento pode causar o aparecimento de comportamentos considerados atípicos para a espécie. Animais mantidos em cativeiro são, de forma geral, expostos a um espaço limitado e de pouca estimulação, levando-os a apresentar quadros de estresse, com distúrbios comportamentais e, em muitos casos, imunossupressão e infecções oportunistas. Como alterativa para minimizar o estresse gerado pelo confinamento, a prática do "enriquecimento ambiental", definida como um conjunto de técnicas de manejo que visam melhorar o ambiente físico e social dos animais, vem sendo amplamente difundida. Durante os últimos anos, o TAMAR de Florianópolis vem instituindo um amplo programa de enriquecimento ambiental para as tartarugas marinhas mantidas no Museu Aberto da Barra da Lagoa.
Item Fatal Citrobacter Coelomitis in a Juvenile Green Turtle (Chelonia mydas): A Case Report(2016) GOLDBERG, D.W.; CEGONI, C.T.; ROGÉRIO, D.W.; WANDERLINDE, J.; LIMA, E.P. E.; SILVEIRA, R.L.; JERDY, H.; CARVALHO, E.C.Q.deGram-negative bacteria are the most common bacterial pathogens among sea turtles, which is not a surprising fact, because gram negative bacteria are common isolates in healthy reptiles (Alfaro et al., 2006). This report describes the post mortem lesions in a juvenile green turtle (Chelonia mydas) that died during rehabilitation due to a severe coelomitis.Item Fatal Citrobacter septicemia in a juvenile green turtle (Chelonia mydas): a case report(2016) GOLDBERG, D.W.; CEGONI, C.T.; ROGÉRIO, D.W.; WANDERLINDE, J.; LIMA, E.P. E.; JERDY, H.; CARVALHO, E.C.Q.deInfections in sea turtles are almost always the result of immunosuppression. Gram-negative bacteria are the most common bacterial pathogens among sea turtles, which is not a surprising fact, since gram-negative bacteria are common isolates in healthy reptiles. This report describes the post mortem lesions in a juvenile green turtle (Chelonia mydas) that died during rehabilitation due to a severe celomitis.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).- SITAMAR:CONNECTING SEA TURTLES INFORMATION TO REACH BETTER CONSERVATION ACTIONS IN BRAZIL(2015-10-20) SANTOS, A.

Item What can we learn from sea turtle strandings?(2016) GOLDBERG, D.W.; PIRES, T.; VELLOSO, R.; BECKER, H.; CASTILHOS, J.C.; WANDERLINDE, J.; LOPEZ, G.G.; MELO, M.T.D.; SANTOS, A.B.; BAPTISTOTTE, C.Stranding datasets may provide important information on sea turtle health, age, size composition, diet, reproductive status, population trends and cause-specific mortality. Additionally, they are also used to infer geographic distribution and abundance or even trends in mortality risk, attributable to anthropogenic threats such as coastal fisheries and pollution. Five species of sea turtle were recorded in 5260 strandings from January 2014 to September 2015, along the Brazilian coast, of which 3903 were Chelonia mydas, 914 were Lepidochelys olivacea, 290 were Caretta caretta, 83 were Eretmochelys imbricata, 4 were Dermochelys coriacea and 66 could not be identified.
