RItem Relationship between fibropapillomatosis and environmental quality: a case study with Chelonia mydas off Brazil.(2010-02-24) SANTOS, R. G; MARTINS, A. S; TOREZANI, E; BAPTISTOTTE, C; FARIAS, J. N; HORTA, P. A; WORK, T. M; BALAZS, G. HWe 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.- Detection and characterization of fibropapilloma-associated turtle herpesvirus in marine turtles for Brazil.(2009-11) RODENBUSCH, C.R; ALMEIDA, L.L; MARKS, F.S; BAPTISTOTTE, C; PIRES, T.T; WERNECK, M.R; DAMASCENO, T; ALIEVI, M.M; CANAL, C.N
- Nesting Biology and conservation of the leatherback sea turtle (Dermochelys coriacea) in Espírito Santo State, Brazil, 1988-1989 to 2003-2004.(Chelonian Conservation and Biology, 2007-05-01) THOMÉ, J. C. A; BAPTISTOTTE, C; MOREIRA, L. M. P; SCALFONI, J. T; ALMEIDA, A. P; RIETH, D. B; BARATA, P. C. RIn Brazil, the only area where regular leatherback sea turtle (Dermochelys coriacea) nesting is known to occur is located on the northern coast of the state of Espı´rito Santo, around latitude 198S. In this study, we present the field methods used by Projeto TAMAR-IBAMA (the Brazilian Sea Turtle Conservation Program) in the state of Espı´rito Santo and analyze data on leatherback nesting from 1988–1989 to 2003–2004. In that period, 527 nests were observed in the study area. The annual number of nests varied between 6 (in 1993–1994) and 92 (in 2002–2003). Between 1995–1996 and 2003–2004, the annual number of nests increased at about 20.4% per year on average. Among the 527 clutches observed, 358 (67.9%) were left in situ, 50 (9.5%) were relocated to another spot on the beach, 88 (16.7%) were relocated to open-air beach hatcheries, and 31 clutches (5.9%) did not have their management decision recorded. Curved carapace length of nesting females was in the range of 139–182 cm (mean ¼ 159.8 cm). At present, there is no significant alteration of the nesting habitat in Espı´rito Santo, egg poaching has been reduced to very low levels, and there is no subsistence hunting for sea turtles of any species. The main challenges to leatherback conservation currently are the incidental capture in artisanal fisheries operating close to nesting beaches and in high seas fisheries operating in the South Atlantic, as well as activities related to the oil industry. An overview of Projeto TAMAR’s actions addressing current sea turtle conservation issues in the State of Espı´rito Santo is presented.
- Sea turtle feeding grounds of Brazil.(1998) MARCOVALDI, M. Â; SILVA, A. C. C. D. da; GALLO, B. M. G; BAPTISTOTTE, C; VIEITAS, C. F; BELLINI, C; LIA, E. H. S. M; CASTILHOS, J. C. de; THOMÉ, J. C. A; SANCHES, T. M
- Reproductive biology and conservation status of the loggerhead sea turtle (Caretta caretta) in Espirito Santo State, Brazil.(2000) BAPTISTOTTE, C; THOMÉ, J. C. A; BJORNDAL, KThe reproductive biology of loggerheads nesting in Espírito Santo, Brazil, is evaluated for six nesting seasons (1991/1992 through 1996/1997), through data gathered by Projeto TAMAR-IBAMA, the Brazilian sea turtle conservation program. Mean curved carapace length of nesting females was 102.7 cm (n=198). Mean clutch size for clutches with more than 50 eggs was 119.7 (n=3664), and clutch size was significantly correlated with female body size. Management practices had significant effects on hatching success and incubation time. Mean hatching success of nests left in situ was 68.3% (n=879), of undepredated nests left in situ was 79.9% (n=751), and of nests moved to hatcheries and not depredated was 67.7% (n=2786). For nests moved to hatcheries, hatching success declined significantly with increasing time interval between oviposition and transfer to the hatchery. Mean incubation time was 59.5 days for nests left in situ (n=572) and 57.2 days for nests moved to hatcheries (n=2179). Incubation time declined significantly throughout the nesting season as temperatures increased; we conclude that sex ratio of hatchlings also shifts to more females as the season progresses. There was significant annual variation for all parameters. A short review of the conservation status of loggerheads in Espírito Santo State is also presented.
