Item Captive-raised Loggerhead Turtle (Caretta caretta) Found Nesting Eight Years After Release(2007) ALMEIDA, A. P.; BAPTISTOTTE, C.; SANTOS, A. S. A.; SERAFINI, T. Z.Item Captive-raised Loggerhead Turtle (Caretta caretta) Found Nesting Eight Years After Release(2007) ALMEIDA, A. P.; BAPTISTOTTE, C.; SANTOS, A. S.; SERAFINI, T. Z.The Brazilian coast between the states of Sergipe and Rio de Janeiro (Figure 1) is considered the most important breeding site of the loggerhead turtle, Caretta caretta in Latin America (Marcovaldi & Marcovaldi 1999), with over 5,000 nests laid annually (Marcovaldi & Chaloupka in review).Item Characterization of Fibropapilloma Associated Turtle Herpesvirus in Green Turtle From Brazil.(2010) RODENBUSCH, C. R; BAPTISTOTTE, C.; MELO, M. T. D; PIRES, T. T; WERNECK, M. R; TOREZANI, E; CANAL, C. WItem 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 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.
- Educational campaign to reduce the impact of artificial light on sea turtle nesting beaches in Brazil.(2000) MARCOVALDI, M. Â; BELLINI, C; CASTILHOS, J. C de; SILVA, A. C. C. D. da; GALLO, B. M. G; BAPTISTOTTE, C.; LIMA, E. H. S. M; LIMA, E. P; SANCHES, T. M; THOMÉ, J; PATIRI, V. J. ASeveral important stages of reproduction by sea turtles normally take place at night, under the cover of darkness on beaches. Artificial lights on or near beaches often reduce the number of female sea turtles that emerge from the ocean to nest (Witherington, 1992; Ehrhart et al. 1996). When females do lay their eggs on beaches that are subject to artificial lighting, seafinding of the resultant hatchling turtles is often disrupted and they often go away from the sea (e.g. Philibosian, 1976; Peters and Verhoeven, 1994). Misoriented hatchlings face increased mortality from land predators, accidental trampling by people or vehicles, or desiccation following sunrise. Development of coastal areas, in the form of homes, hotels, industrial complexes, and recreational areas, leads to an increase of nighttime lighting. Unchecked lighting on beaches used by sea turtles can have serious impacts on nesting populations, and as such management of lighting on or near beaches is a priority for most sea turtle conservation programs.
- Geographical and temporal patterns of green turtle occurrence along the southwestern Atlantic coast(2016) BARATA, P.C.R.; CARMAN, V.G.; FALLABRINO, A.; SANTOS, A.S.; BONDIOLI, C.V.; ESTRADES, A.; SANTOS, A.J.B.; SILVA, A.C.C.D.; SILVA, B.M.G.; GIFFONI, B.B.; DOMIT, C.; BAPTISTOTTE, C.; BELLINI, C.; BATISTA, C.M.P.; BEZERRA, D.P.; MONTEIRO, D.S.; RIETH, D.; ALBAREDA, D.; LIMA, E.H.S.M.; LIMA, E.P.; GUEBERT, F.; VELEZ-RUBIO, G.M.; SALES, G.; LOPEZ, G.G.; STAHELIN, G.D.; BRUNO, I.; CASTILHOS, J.C.; THOME, J.C.A.; BECKER, J.H.; NARO-MACIEL, E.; MASCARENHAS, R.; WANDERLINDE, J.; MARCOVALDI, M.A.; BARROS, J.; ESTIMA, S.C.; MELO, M.T.D.; ROSA, L.
Item Identification of loggerhead male producing beaches in the south Atlantic: Implications for conservation.(2016-01-04) ARCOVALDI, M.A.G.; LÓPES-MENDILAHARSU, M.; SANTOS, A.S; LOPEZ, G.G.; GODFREY, M.H.; TOGNIN, F.; BAPTISTOTTE, C.; THOMÉ, J.C.; DIAS, A.C.C.; CASTILHOS, J.C.; FUENTES, M.M.P.B.Concern over the potential impacts of increased temperature on marine turtles, which have temperature dependent sex determination, has resulted in an increase in research that predicts the sex ratio of marine turtle hatchlings under various scenarios of climate change. To accurately understand the projected impacts from global warming, it is necessary to understand the sex ratio baseline in advance of climate change. To address this, the primary sex ratio of loggerhead hatchlings, Caretta caretta, was estimated from incubation duration of 27,697 in situ nests from 21 nesting beaches used by two subpopulations of loggerhead turtles in Brazil over the last 25 years. A strong female bias (94%) was observed in all the areas used by the northern loggerhead stock, Sergipe (SE) and Bahia (BA), whereas a more balanced sex ratio (53% female) was estimated at the regions used by the southern loggerhead stock, Espirito Santo (ES) and Rio de Janeiro (RJ). Both inter-annual (SE: 83% to 99%, BA: 79. % to 98%, ES: 33% to 81%, RJ: 18% to 81%) and inter-beach variabilities (SE: 91% to 98%, BA: 89% to 96%, ES: 47% to 69%, RJ: 28% to 55%) in mean female offspring were observed. These findings provide evidence of persistent female bias in Brazil, and importantly identify male producing beaches and months, which will guide management decisions.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 NOT JUST ANOTHER MIXED STOCK ANALYSIS(2010) NARIO-MACIEL, E.; MARTIN, M.; BONDIOLI, A. 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.- Novos índices de longevidade reprodutiva para a careba-amarela (Caretta caretta) no litoral do Espírito Santo, Brasil.(2005) THOMÉ, J.

G.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 Relationship between fibropapillomatosis and environmental quality(2010-02-24) SANTOS, R. G.; MARTINS, A. S.; TOREZANI, E.; BAPTISTOTTE, C.; FARIAS, J. N.; HORTA, P. A.; WORK, T. M.; BALAZS, G. H.We documented the presence of fibropapillomatosis (FP), a debilitating tumor-forming disease, in marine turtles in Espírito Santo Bay (Brazil) from March 2007 to April 2008, and assessed the value of a specific environmental index for predicting the prevalence of FP. Turtles were captured monthly with entanglement nets and scored for presence and severity of FP. For the assessment of habitat quality, we used the ecological evaluation index (EEI) based on benthic macrophytes. The FPfree control area was classified as good quality (EEI = 8) and the study area, with high FP prevalence, was classified as bad quality (EEI = 2). Prevalence of FP in the study area was 58.3% with an average of 40 tumors per individual, and prevalence varied positively with curved carapace length (CCL). No FP was seen in the control area. The number of turtles heavily afflicted (tumor score category 3) was 10 times larger than those lightly affected (tumor score category 1). Most tumors were found on or near the front and rear flippers; no oral tumors or internal tumors were found. At recapture, 41% of formerly tumor-free turtles revealed FP, often increasing in severity with time, and very few turtles showed signs of disease regression. From the results of this study we concluded that FP is particularly severe in Espírito Santo Bay. Future studies should focus on evaluating how widespread FP is in Brazil, whether prevalence is increasing or decreasing, and elucidating the pathology and pathogenesis of FP in sea turtles in Brazil.- SITAMAR:CONNECTING SEA TURTLES INFORMATION TO REACH BETTER CONSERVATION ACTIONS IN BRAZIL(2015-10-20) SANTOS, A.

- Variação Latidutinal na Distribuição do Tamanho de Tartarugas-verdes (Chelonia mydas) ao Longo de Parte da Costa Leste da América do Sul(2011-11-27) BARATA, P. C. R.; CARMAN, V. G.; SANTOS, A.

A.; BECKER, J. H.; WANDERLINDE, J.; ROSA, L.; MARCOVALDI, M. A. G.; MELO, M. T. D.; MASCARENHAS, R.; ESTIMA, S. C.; NARO-MACIEL, E.As tartarugas-verdes (Chelonia mydas), após o nascimento nas praias de desova e um período de alguns anos na zona oceânica do mar, realizam, quando juvenis pequenas, uma mudança para a zona nerítica (Musick e Limpus 1997). A transição da zona oceânica para a zona nerítica e a distribuição geográfica de juvenis e adultos pelas áreas de alimentação costeiras ainda são insuficientemente conhecidas, assim como os fatores que as definem. O conhecimento destes aspectos da história natural das tartarugas-verdes, além de nos permitir um melhor entendimento da sua biologia populacional, tem implicações para a conservação da espécie, por possibilitar o estabelecimento de relações mais claras entre áreas geográficas, estágios ontogenéticos das tartarugas, fatores ambientais ou de outra ordem e ações de conservação. A tartaruga-verde atualmente está classificada como Ameaçada pela União Internacional para a Conservação da Natureza (IUCN). A tartaruga-verde tem ampla distribuição na costa leste da América do Sul (Pritchard 1976; Marcovaldi e Marcovaldi 1999; González Carman et al. 2011). Este trabalho tem como objetivo analisar a variação, em larga escala, da distribuição do tamanho (medido pelo comprimento curvo da carapaça, CCC) das tartarugas-verdes ao longo de parte da costa leste da América do Sul, com dados obtidos em áreas costeiras, com vistas a uma melhor compreensão da biogeografia da espécie na região.
