1. Green turtle (Chelonia mydas) genetic diversity at Paranaguá Estuarine Complex feeding grounds in Brazil
Sea turtles are marine reptiles that undertake long migrations through their life, with limited information regarding juvenile stages. Feeding grounds (FGs), where they spend most of their lives, are composed by individuals from different natal origins, known as mixed stock populations. The aim of this study was to assess genetic composition, natal origins a

2. Efeitos das mudanças socioecológicas sobre a pesca artesanal e a captura incidental de Tartarugas Marinhas no Bairro São Francisco (São Sebastião, São Paulo) / Social-ecological change effects on artisanal fisheries and sea turtle by cath in São Francisco (São Sebastião, São Paulo)
O objetivo deste estudo foi investigar como as mudanças sócio ecológicas afetam a pesca artesanal e a captura incidental de tartarugas marinhas no bairro São Francisco (São Sebastião, São Paulo) e como os pescadores estão respondendo às alterações nos últimos 60 anos. Para tanto, a capacidade adaptativa de sistemas complexos e o conhecimento ecol

3. Anatomy of the digestive tube of sea turtles (Reptilia: Testudines)
This study characterized the morphology of the digestive tube of five species of sea turtles. We used specimens found dead along the coast of the state Rio Grande do Norte, as well as specimens accidentally killed as a result of pelagic longline fishing. Nineteen animals of the following species were analyzed: Chelonia mydas (Linnaeus, 1758) (n = 9), Lepidoc

4. Ecologia e Conservação de Tartarugas Marinhas Através da Análise de Encalhes no Litoral Paraibano
Five sea turtle species use the Brazilian coast for reproduction and feeding: loggerhead turtle (Caretta caretta), green turtle (Chelonia mydas), leatherback turtle (Dermochelys coriacea), olive turtle (Lepidochelys olivacea) and hawksbill turtle (Eretmochelys imbricata). These species are included in the threatened categories, as much globally, according to

5. Idade e crescimento da tartaruga-cabeçuda (Caretta caretta) no litoral sul do Rio Grande do Sul / Age and growth of loggerhead sea turtle (Caretta caretta) in Southern Brazil
The juvenile and sub-adult stages of loggerhead sea turtles (Caretta caretta) are poorly studied in Brazil. We present age estimates and a growth model for loggerhead sea turtles in the South Atlantic Ocean obtained through skeletochronological analysis of humeri obtained from both neritic and oceanic stage individuals. Since it was validated that each incre

6. Turtle cleaners: reef fishes foraging on epibionts of sea turtles in the tropical Southwestern Atlantic, with a summary of this association type
No presente estudo registramos diversos episódios de peixes recifais alimentando-se de epibiontes sobre o corpo de tartarugas marinhas (simbiose de limpeza) nas ilhas oceânicas do arquipélago de Fernando de Noronha e próximo a um naufrágio na costa de Pernambuco, nordeste do Brasil. Nove espécies de peixes recifais e três espécies de tartarugas envol

7. DNA barcoding of Brazilian sea turtles (Testudines)
Five out of the seven recognized species of sea turtles (Testudines) occur on the Brazilian coast. The Barcode Initiative is an effort to undertake a molecular inventory of Earth biodiversity. Cytochrome Oxidase c subunit I (COI) molecular tags for sea turtle species have not yet been described. In this study, COI sequences for the five species of sea turtle

8. Estrutura populacional e variabilidade genética de tartaruga verde (Chelonia mydas) da região de Cananéia, São Paulo / Populational structure and genetic variability of green sea turtle (Chelonia mydas) from Cananéia, São Paulo
The green turtle, Chelonia mydas, is an endangered marine reptile that nests and forages along the Brazilian coast and oceanic islands, among other tropical areas. Due to the highly migratory and oceanic nature of these animals, ecological studies are many times difficult to carry out, and many questions about their biology remain. Molecular genetic analysis

9. Ocorrência de Pesticidas Organoclorados e Bifenilos Policlorados em tartarugas marinhas Chelonia mydas / Occurrence of organochlorine pesticides and polychlorinated biphenyls in sea turtles Chelonia mydas
Organochlorine compounds, such as pesticides and polychlorinated biphenyls (PCBs), are persistent, toxics and widely distributed due to the atmospheric transport and oceanic currents. Few studies have reported the occurrence of these compounds in turtles, but none from the Brazilian Coast. Chelonia mydas is the biggest marine turtle with hard carapace that e

10. Geobiologia do Atol das Rocas, Atlântico Sul Equatorial
This thesis approaches the geobiology of the only Atoll in the South Atlantic Ocean. Different classifications were made for Rocas Reef Complex along the nineteenth and twentieth century, which are evaluated historically. Biogeomorphological analysis and mapping of the reef units were done on the Rocas Atoll for the comprehension of the sedimentary dynamic a

11. Influence of artificial magnetic fields upon the behavior of the shrimp Litopenaeus vannamei (PENAEIDAE) and fish catch using fishtraps / InfluÃncia do campo magnÃtico artificial sobre o comportamento do camarÃo Litopenaeus Vannamei (PENAEIDAE) e a captura de peixes na pesca com covos
This work focuses on the behavior of marine organisms (fishes and shrimps) when submitted to artificial magnetic fields and on the use of this behavior as a mechanism to attract or to move away these organisms to/for specific areas. Although the geomagnetic field has existed in the planet a long time before of the beginning of the life rise little is known a

12. Spatiotemporal characterization of fibropapillomatosis in sea turtles of the Brazilian Coast / Caracterização espacial e temporal da fibropapilomatose em tartarugas marinhas da costa brasileira
Fibropapilomatose (FP) é uma doença caracterizada por múltiplas massas de tumores cutâneos variando de 0,1 a mais de 30 cm em diâmetro. Afeta primariamente tartarugas-verdes (Chelonia mydas), mas também outras espécies de tartarugas marinhas ao redor do mundo. O objetivo deste estudo é, através de dados já sistematicamente coletados pelo Programa B
