- Aspectos da biologia reprodutiva de Caretta caretta no litoral norte do Espírito Santo, evidenciados por recapturas de fêmeas marcadas.(2002) ALMEIDA, A. P; THOMÉ, J. C. A; BAPTISTOTTE, C; MOREIRA, L. M. P; RIETH, D. B; SCALFONI, J. T
Item Atypical ocular Chelonoid herpesvirus manifestations in a captive Loggerhead turtle (Caretta caretta)(Veterinary Ophthalmology, 2021) Oriá, Arianne P. et al.A captive loggerhead turtle (Caretta caretta) of unknown sex, 3 years of age, presented with bilateral mucoid secretions, severe chemosis, conjunctival hyperemia, and globe retraction. The animal was evaluated ophthalmologically and systemically, and hematological, microbiological, and conjunctival cytological and biopsy samples were collected for complementary diagnosis. The histopathological examination showed amphophilic intranuclear inclusions associated with severe inflammatory infiltrate. The diagnosis of Chelonid alphaherpesvirus 5 (ChAHV 5) was confirmed with end point PCR. Following systemic treatment with L-lysine, acyclovir and vitamin A, the ocular signs resolved. No amphophilic intranuclear inclusions were seen in a follow-up biopsy 5 months later, and there has been no recurrence of clinical ophthalmic signs during a 4-year follow-up. It is suggested that ChAHV 5 be considered as a differential diagnosis in captive marine turtles that present for conjunctival disease other than fibropapillomatosis.- Novos índices de longevidade reprodutiva para a careba-amarela (Caretta caretta) no litoral do Espírito Santo, Brasil.(2005) THOMÉ, J.

- 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.
Item Sattelite-tracking of female loggerhead turtles highlights fidelity behavior in northeastern Brazil(2010-08-11) Marcovaldi, Maria Ângela; Lopez, Gustave G.; Soares, Luciano S.; Lima, Eduardo H. S. M.; Thomé, João C. A.; Almeida, Antonio P.ABSTRACT: We studied inter- and postnesting movements in the major loggerhead Caretta caretta nesting population in Brazil. Ten breeding females were satellite-tracked from nesting grounds in the state of Bahia, northeastern Brazil, for up to 1284 d. Eight females stayed in the nesting area after deployment, showing fidelity between internesting home ranges and nesting locations, even at a local scale. During postnesting movements, all of the turtles migrated to the northern coast of Brazil to individual foraging areas on the continental shelf. Distances between nesting and foraging areas reached up to 2400 km, and migration lasted from 28 to 47 d. Five females were tracked during subsequent breeding migrations to the nesting area at different remigration intervals of 2 or 3 yr. Females were also tracked during a second postnesting migration back to foraging areas, and these showed strong fidelity to foraging grounds. Movements to and from foraging grounds occurred along the shelf, clearly delineating a migratory corridor. The northern coast of Brazil, specifically the coast of the state of Ceará, is an important foraging ground for loggerheads nesting along the northern coast of Bahia.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.
