1. Preliminary data on the occurrence of marine turtles in the Laje de Santos Marine State Park (SP, Brazil)
Resumo Apesar de serem muito observadas por mergulhadores, poucos trabalhos científicos foram realizados com as tartarugas marinhas no Parque Estadual Marinho da Laje de Santos (PEMLS). No período entre 2013 e 2015 campanhas diurnas e noturnas foram realizadas para maior abrangência deste estudo, totalizando 42 horas de observações e 41 tartarugas captu

2. 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

3. 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

4. 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

5. 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

6. 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

7. 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

8. Turtle riders: remoras on marine turtles in Southwest Atlantic
Uma visão geé apresentada sobre uma relação pouco documentada entre vertebrados recifais no Atlântico Sul Ocidental: rêmoras (Echeneidae) associadas a tartarugas marinhas. Duas espécies de rêmora ou pegador (Echeneis naucrates e Remora remora) e quatro de tartarugas (Caretta caretta, Chelonia mydas, Eretmochelys imbricata e Dermochelys coriacea) são

9. Caracterização da captura incidental de tartarugas marinhas pela pesca de espinhel pelágico no Nordeste do Brasil
The marine turtles biological characteristics and the impact they have been suffering in consequence of human activities have caused in the last decades the decrease of populations to unsustainable levels. All four of the species described in this paper are registered as endangered in a list by IUCN: Caretta caretta, Lepidochelys olivacea, Chelonia mydas, De

10. Detection of Antibodies to a Disease-Associated Herpesvirus of the Green Turtle, Chelonia mydas
Lung-eye-trachea disease-associated herpesvirus (LETV) is linked with morbidity and mortality in mariculture-reared green turtles, but its prevalence among and impact on wild marine turtle populations is unknown. An enzyme-linked immunosorbent assay (ELISA) was developed for detection of anti-LETV antibodies and could distinguish LETV-exposed green turtles f

11. A molecular phylogeny for marine turtles: trait mapping, rate assessment, and conservation relevance.
Nucleotide sequences from the cytochrome b gene of mitochondrial DNA were employed to resolve phylogenetic controversies and to assess molecular evolutionary rates in marine turtles (Chelonioidea). Findings of special relevance to conservation biology include discovery of a distant relationship between Natator and other cheloniid species, the paraphyly of Ch

12. Polyandry in a marine turtle: Females make the best of a bad job
The female perspective on reproductive strategies remains one of the most active areas of debate in biology. Even though a single mating is often sufficient to satisfy the fertilization needs of most females and the act of further mating incurs costs, multiple paternity within broods or clutches is a common observation in nature. Direct or indirect advantage
