This dissertation focuses on the hawksbill turtle (Eretmochelys imbricata) in Brazil as a case study for exploring strategies that can enhance marine conservation efforts. Recognized as keystone species for their ecological significance and classified as "Critically Endangered" by the International Union for Conservation of Nature (IUCN), the charismatic flagship species, hawksbill turtle, serves as sentinel, important indicator for the health of tropical to temperate marine ecosystems. Utilizing satellite telemetry and population monitoring, key demographic parameters and spatial ecology of nesting hawksbill turtles were investigated. The overlap between utilization distribution by tracked turtles, Marine Protected Areas (MPAs) and the potential threats, offered insights into broader marine conservation strategies.The second chapter advances our understanding of marine turtle population dynamics by refining the accuracy of demographic parameter estimates, specifically clutch frequency, which is pivotal for assessing marine turtle populations. This parameter is broadly used to estimate number of individual nesting females based on the total number of nests, which often times is the only information available. In addition, this chapter demonstrates the significant impact of the presence of transient turtles on these estimates, which is informative for study designs that aim at estimating the total number of nesting females within a season or the population at large.The third chapter breaks down hawksbill turtle nesting, foraging, and migratory behaviors to inform conservation management. A significant contribution of this work is the identification of key migratory corridors and foraging areas, particularly for the subpopulation from Rio Grande do Norte, Brazil, which highlights the need for spatially explicit conservation goals and targets. The effectiveness of Brazil's coastal MPAs in protecting the vital habitats for nesting hawksbill turtles was assessed. The findings reveal shortcomings in the current MPA network, leading to recommendations for strategic MPA expansion and management, emphasizing ecological-scale approaches over political boundaries to accommodate the species' extensive migratory patterns. The research advocates for MPAs to not only cover high-use areas identified through telemetry but also to implement protection levels tailored to the hawksbill turtles' specific needs.The fourth chapter provides a detailed information of hawksbill turtle interesting behavior, using a novel approach to discretize hidden behaviors during this critical period. In addition to demonstrating high fidelity to nesting beaches and residence areas, mapping the behaviors provided essential insights into their vulnerability to specific threats, including vessel strikes and accidental capture in fishing gear. The research proposes evidence-based strategies to enhance MPA effectiveness, integrating technological advancements with conservation biology to inform policy and management decisions. The study's findings underscore the importance of adaptive management strategies, responsive to the evolving understanding of hawksbill turtle ecology.Beyond hawksbill turtles, the research offers a framework for applying similar conservation strategies to other marine species, underlining the potential for species-specific efforts to catalyze broader and effective environmental management and conservation. The dissertation calls for continued research and adaptive management in response to the dynamic nature of marine ecosystems and emerging threats, highlighting the role of science in effective conservation policies.
