Item REABILITAÇÃO DE TARTARUGAS MARINHAS NAS BASES DO PROJETO TAMAR – ICMBio, NA COSTA BRASILEIRA(2008) WERNECK, M. R.; TADASHI, E.; PIRES, T. T.; MELO, M. T. D.; CASTILHO, J.; BAPTISTOTTE, C.O Projeto TAMAR-ICMBio, atua desde 1980, com o objetivo de proteger as espécies de tartarugas marinhas na costa brasileira. Bases de campo foram implantadas em áreas de desova e áreas de alimentação, onde são encontradas cinco das sete espécies existentes no mundo: Caretta caretta, Chelonia mydas, Eretmochelys imbricata, Lepidochelys olivacea e Dermochelys coriacea.Item CHARACTERIZATION OF FIBROPAPILLOMA-ASSOCIATED TURTLE HERPESVIRUS IN GREEN TURTLES FROM BRAZIL(2010) RODENBUSCH, C. R.; BAPTISTOTTE, C.; MELO, M. T. D.; PIRES, T. T.; WERNECK, M. R.; TOREZANI, E.; CANAL, C. W.The fibropapillomatosis is an emerging disease with high prevalence in turtles and characterized by multiple papillomas, fibromas and fibropapillomas in the skin or viscera. This disease is called "green turtle fibropapillomatosis” (GTFP) because it was first recorded in green turtles. In the Brazil, the first record of GTFP was in 1986 in the state of Espírito Santo (ES), and during the period of 2000-2004, 14.96% of the 4471 green turtles examined had tumors. The etiologic agent of GTFP is still uncertain, but the patterns of disease spread during outbreaks among captive green turtles have shown a pattern of infectious etiology.Item Juvenile green turtles (Chelonia mydas) in the effluent discharge channel of a steel plant, Espírito Santo, Brazil, 2000–2006(2010) TOREZANI, E.; BAPTISTOTTE, C.; MENDES, S. L.; BARATA, P. C. R.; Marine Biological Association of the United KingdomThis study, carried out from August 2000 to July 2006, began out of the recognition of a special ecological situation, when an aggregation of juvenile green turtles (Chelonia mydas) was found inside the effluent discharge channel of a steel plant located near Vito´ria, the State of Espı´rito Santo capital, eastern Brazil. The green turtles were captured through either cast nets or a set net or by hand (one turtle was captured alive on one of the channel banks); after data collection, they were released back into the discharge channel. Information is here reported on the temporal pattern of occurrence, size-classes, residency, presence of tumours and growth rates of tumoured and non-tumoured green turtles in the study area. A total of 640 individual green turtles were captured in the six years; 448 of them were captured just once, and 192 were captured two or more times. Curved carapace length ranged between 25.2 and 77.5 cm. Among the captured green turtles, 59.1% were classified as being in normal body condition and without any tumours, 6.6% were either underweight or emaciated but without any tumours, and 34.4% had tumours, with different levels of the tumour severity score.Item DETECTION AND CHARACTERIZATION OF FIBROPAPILLOMA-ASSOCIATED TURTLE HERPES-VIRUS IN MARINE TURTLES FROM BRAZIL(2009) ALMEIDA, L. L.; MARKS, F. S.; BAPTISTOTTE, C.; PIRES, T. T.; WERNECK, M. R.; DAMASCENO, T.; ALLIEVE, M.; CANAL, C. W.- DETECTION AND CHARACTERIZATION OF FIBROPAPILLOMA-ASSOCIATED TURTLE HERPESVIRUS IN MARINE TURTLES FROM BRAZIL(2009) RODENBUSH, C. R.; ALMEIDA, L. L.; MARKS, F. S.; BAPTISTOTTE, C.; PIRES, T. T.; WERNECK, M. R.; DAMASCENO, T.; ALLIEVE, M.; CANAl, C. W.Fibropapillomatosis (FP) is a neoplasic disease of marine turtles characterized by the presence of epithelial fibropapillomas and internal fibromas. Although the tumors are considered bening, the disease can be life-threatening; large cutaneous tumors can interfere with the turtles' locomotion, vision, swallowing, and breath-ing, and visceral tumors can be locally invasive and affect organ function.

C. V.; ALMEIDA, A. P.; TOREZANI, E.; BAPTISTOTTE, C.; MARCOVALDI, M. A.; AMATO, G.; DESALLE, R.In the Southwestern Atlantic Ocean, sea turtles are exposed to myriad threats including disease, fisheries bycatch, and industrial or coastal development, but protected by effective conservation organizations. In Espírito Santo, Brazil, green turtles (Chelonia mydas) with relatively high incidence of fibropapillomatosis tumors routinely strand in the vicinity of the state capital, Vitória, a highly urbanized area that encompasses the effluent discharge channel of a local steel plant. This is also a particularly interesting population because of its relative proximity to the regionally important Trindade Island rookery, whose feeding grounds have not been convincingly identified to date. To investigate the population distribution of the at-risk turtles, we sequenced a segment of the mitochondrial control region (862 bp; n = 132). Eight mtDNA haplotypes were revealed, of which the most common were CMA-08 and CMA-05. Haplotypes CMA-06 and CMA-09 were each found in six individuals, and rare haplotypes CMA-03, CMA-10, CMA-23, and CMA-32 were also detected. Two kinds of “many-to-many” mixed stock analyses were carried out, taking into account or alternately disregarding source nesting population size. The same approach was taken with traditional MSAs (“one-to-many”), and the main differences between the "one-to-many" and "many-to-many" results are reported. The analyses that included population size and all available data were most consistent with expectations. We recommend caution when employing different mixed stock analysis methods, and emphasize the importance of exploring alternate ways of investigating the origins of mixed stocks, including modeling approaches. These data will provide insight into population isolation and conservation priorities necessary to establish whether areas should be managed as independent units or as regional populations, and will clarify questions of scale in conservation and management, providing a scientific basis for conservation prioritization.Item Captive-raised Loggerhead Turtle (Caretta caretta) Found Nesting Eight Years After Release(2007) ALMEIDA, A.
