| Resumo: | Five species of sea turtles occur in the Brazilian coast. These species are globally threatened according to the International Union for Conservation of Nature, but alsolocally threatened according to the Livro Vermelho da Fauna Brasileira. Among these five species, the hawksbill turtle (Eretmochelys imbricata) is the most threatened, categorized as critically endangered. Historically, the main threats to this species have been the shell trade, egg collection and female harvesting for human consumption. Currently, the main factors responsible for population decline are incidental catch in fishing, entanglement and ingestion of marine debris, photo-pollution and destruction of nesting habitats. The objective of this work was to perform a systematic review of the published literature on Eretmochelys imbricata in Brazil and to quantify research efforts over time, space and study topics. During three decades, between 1990 and 2018, we collected information from 66 articles. We found a gradual growth of publications over time, with the first decade gathering 6% of the articles, the second 28% and the last one gathered 67%. The articles were published in 32 different journals, but most articles were published in the journal Marine Turtle Newsletter. Among the eight general topics addressed in the articles, ecology was the most studied with 37% of the articles, with greater emphasis in the specific topic reproductive biology. The second most studied topic was threats, in 16% of the articles, with the most recurrent specific topic being debris ingestion and fishing interactions. The studies covered almost the entire Brazilian coast (15 states). Bahia was the state with the largest number of studies, followed by Pernambuco and Rio Grande do Norte. Most articles had their study areas limited to one municipality, especially Camaçari and Mata de São João (BA). Tibau do Sul (RN) was the third municipality with the largest number of articles. Among the islands, Fernando de Noronha had the largest number of published articles. |
