    There is a lack of published information regarding reproductive endocrinology for most turtle species. In the case of marine turtles that are frequently exposed to manyenvironmental challenges, more information on their reproductive physiology andbehavior is essential for understanding how they function in their ecosystems. In Brazil, green turtles (Chelonia mydas) are one of the most common marine turtle species. The Biological Reserve Atol das Rocas (03º51´30"S e 33º49´29"W), 144 miles off northeast Brazil, is one of the nesting sites of Chelonia mydas in the West Atlantic. Every year during the nesting season (December–June), around 100 females nest on its sandybeaches. Reproductive activity peaked in March. In April 2004, we collected blood samples from 44 adult females immediately after oviposition. Samples were collected by venipuncture of the postoccipital venous plexus and the serum was frozen at - 30°C until it could be transported to the Department of Animal Reproduction at theUniversity of São Paulo for processing. The samples were assayed using commercial kits for estradiol (Double Antibody-DSL, Webster, TX, USA), progesterone and testosterone (Coat-a-Count, DPC, Los Angeles, CA, USA). The hormonal levels (mean ±SD) of the green turtle females were: Estradiol 3.06 ± 1.66 pg/ml, Progesterone 1.20 ± 1.65 ng/ml and Testosterone 45.04 ± 26.47 ng/ml. This information not only increases our knowledge of the endocrine-reproductive system of this endangered species but also serves as a baseline against which to assess results from future studies.

    Juvenile green turtles (Chelonia mydas) in the effluent discharge channel of a steel plant, Espírito Santo, Brazil, 2000-2006.
    (Journal of the Marine Biological Association of the United Kingdom, 2010-03) Torezani, E; Baptistotte, Cecília; Mendes, S. L; Barata, P. C. R
    This 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

    In the 35 years since its inception, the Brazilian National Program for the Conservation of Marine Turtles (TAMAR) has had great success in protecting the five species of sea turtles that occur in Brazil. It has also contributed significantly to worldwide scientific data and knowledge about these species’ biology, such as life cycles and migration patterns. TAMAR’s conservation strategies have always relied on a variety of environmental education and social inclusion (EESI) activities highly adapted to the socioenvironmental evolving contexts of its 25 locations distributed across nine states. Diversity and flexibility are critical to enable timely and effective local responses to existing or potential threats to sea turtles. The intuitive, locally adapted, decentralized, and independent way EESI activities have been carried out have generated positive results in the resolution of specific and evolving local problems through the course of the project. This article brings EESI under the same conceptual framework that underlies its conservation approach by adopting an adaptive threat management framework to organize and qualify its educational and social inclusion interventions according to the main categories of threat addressed by TAMAR.

    A publicação Guia de Licenciamento - Tartarugas Marinhas foi elaborada por meio da pesquisa, levantamento de informações e redação técnica fundamentada na bibliografia especializada e por meio das experiências acumuladas pelos servidores do CENTRO TAMAR/ICMBio, em conjunto com instituições parceiras, sobre as tartarugas marinhas. O grupo que participou desta 2ª Edição é composto por servidores e pesquisadores do ICMBio, pesquisadores de instituições da Rede de Parceiros, formada por universidades e ONGs que atuam na conservação das cinco espécies de tartarugas marinhas que ocorrem na costa brasileira (Dermochelys coriacea; Eretmochelys imbricata; Lepidochelys olivacea, Chelonia mydas e Caretta caretta). O objetivo principal desta obra é apresentar subsídios aos órgãos ambientais que promovem análises de licenciamento (nos níveis federal, estaduais e municipais); bem como a empreendedores e empresas de consultoria na área ambiental envolvidos na elaboração de estudos ambientais e empreendimentos previstos para serem implementados nas áreas importantes para a conservação das tartarugas marinhas; além de a pesquisadores e estudiosos dessas espécies e seus habitat.
