Correlation between trace element concentrations in the blood of female hawksbi...
Morão, Inês; Simões, Tiago; Busom Casado, Roger; Vieira, Sara; Ferreira-Airaud, Betânia; Caliani, Ilaria; Di Noi, Agata; Casini, Silvia; Fossi, Maria C.Metals and metalloids can pose a significant threat to sea turtles, as these contaminants tend to accumulate in their bodies over time, due to their long lifespans and varied feeding habits. São Tomé and Príncipe's archipelago hosts the last remaining rookery for hawksbill sea turtles (Eretmochelys imbricata) in the region. The study aimed to determine the levels of metals and metalloids accumulated by this pop...
Discriminative influence of persistent organic pollutants on nesting green sea ...
Morão, Inês; Muñoz-Arnanz, Juan; Simões, Tiago; Bartalini, Alice; Vieira, Sara; Ferreira-Airaud, Betânia; Caliani, Ilaria; Noi, Agata Di; Casini, SilviaPersistent organic pollutants (POPs) including polychlorinated biphenyls (PCBs), polybrominated diphenyl ethers (PBDEs), and organochloride pesticides (OCPs) affect biodiversity by bioaccumulating through food webs, impacting marine organisms like endangered sea turtles. This study represents the first evaluation of these contaminants in sea turtles nesting in São Tomé and Príncipe. The main goal was to evaluat...

Updated global conservation status and priorities for marine turtles
Wallace, B. P.; Bandimere, A. N.; Abreu-Grobois, F. A.; Acosta, H.; Akiti, J.; Akomedi, M.; Alfaro-Shigueto, J.; Allen, C. D.; Angenda, D.; Ayissi, I.Assessing conservation status and pursuing applicable management priorities for marine megafauna across multiple scales pose significant challenges. Because marine turtles exemplify these challenges, the IUCN Marine Turtle Specialist Group (MTSG) developed the 'conservation priorities portfolio' (CPP) framework in 2011 to evaluate population risk and threats for regional management units (RMUs). Here, the MTSG ...
Metal accumulation in female green sea turtles (Chelonia mydas) from Eastern At...
Morão, Inês F.C.; Simões, Tiago; Casado, Roger B.; Vieira, Sara; Ferreira-Airaud, Betânia; Caliani, Ilaria; Noi, Agata Di; Casini, SilviaSea turtles, with their global distribution and complex life cycle, often accumulate pollutants such as metals and metalloids due to their extended lifespan and feeding habits. However, there are limited studies exploring the impact of metal pollution on the reproductive health of female sea turtles, specifically focusing on the quality of their eggs, which has significant implications for the future generation...
Green and Hawksbill sea turtles of Eastern Atlantic: new insights into a global...
Ferreira-Airaud, Betânia; Vieira, Sara; Branco, Maria; Pina, Antunes; Soares, Venceslau; Tiwari, Manjula; Witt, Matthew; Castilho, Rita; Teodosio, MariaSea turtles are critical components of marine ecosystems, and their conservation is important for Ocean Governance and Global Planet Health. However, there is limited knowledge of their ecology in the Gulf of Guinea. To fill this knowledge gap, this study presents the first integrative assessment of green and hawksbill turtles in the region, combining nesting surveys over 9 years and telemetry data, to offer in...
