Identifying developmental habitat is essential for understanding population structure and species resiliency, especially for critically endangered species. In long-lived, oceanic, migratory animals such as sea turtles, elucidating developmental grounds is particularly difficult. When data are deficient or challenging to acquire, scientists often lean towards traditional quantitative methods when a social-ecological systems approach could better provide crucial baseline data and guiding information. Fishers' ecological knowledge (FEK), the combination of experiential and culturally transmitted knowledge, is expert knowledge and should be treated as such. In 2008, FEK led to the "rediscovery" of the critically endangered eastern Pacific (EP) population of hawksbill sea turtles (Eretmochelys imbricata), which nests within an unusual habitat: on the shores of mangrove estuaries. However, we did not know how extensively EP hawksbills use these mangrove estuary habitats throughout ontogeny. To answer this question, we use a social-ecological systems approach, illuminating FEK through participatory action research and informant-directed semi-structured interviews, and integrating FEK with stable isotope analysis. Together, this approach reveals that mangrove estuary habitat is crucial for the development of immature EP hawksbills. Further, this imperiled population exhibits a pelagic stage that puts them at risk to artisanal fisheries before recruiting into their estuarine developmental grounds-where some stay until adulthood. These findings will improve how we conserve this population, highlight the substantial impact social-ecological systems approaches have on conservation, and demonstrate how interdisciplinary studies can reveal data of a revolutionary nature.

520 $a La identificacion del habitat de desarrollo de especies, especialmente para las especies en peligro de extincion critico, es esencial para comprender la estructura de la poblacion y la resiliencia de la especie. En el caso de animales migratorios oceanicos de larga vida, como las tortugas marinas, identificar el habitat de desarrollo es particularmente dificil. Cuando hay una deficiencia de datos o estos son dificiles de adquirir, los cientificos se inclinan a usar los metodos cuantitativos tradicionales, sin embargo un enfoque de sistemas socio-ecologicos podria ofrecer mejores datos de referencia. El conocimiento ecologico de los pescadores (CEP) es la combinacion de conocimiento adquirido a traves de la experiencia vivida y la sabiduria cultural. El CEP es un conocimiento experto y debe ser reconocido como tal. En 2008, CEP llevo al "redescubrimiento" de la poblacion de las tortugas carey (Eretmochelys imbricata) del Pacifico oriental (PO), que anidan en un habitat inusual: los estuarios de manglares. Esta poblacion esta en peligro critico de extincion y no sabiamos que tanto las tortugas carey del PO dependen de los manglares a lo largo de sus vidas. Para identificar que tanto la tortuga carey del PO dependen de los manglares, utilizamos un enfoque de sistemas socio-ecologicos, iluminando CEP a traves de investigacion accion participativa y entrevistas semiestructuradas dirigidas por informantes, e integrando CEP con analisis de isotopos estables. En conjunto, este disertacion revela que el habitat del estuario de manglar es crucial para el desarrollo de la tortuga carey inmaduras del PO. Ademas, esta poblacion exhibe una etapa pelagica que los pone en riesgo debido a las actividades de pesca artesanal antes de la transicion al estuario, donde algunos permanecen hasta la madurez. Estos resultados mejoraran la forma en que conservamos esta poblacion, destacaran el impacto sustancial de los enfoques de los sistemas socio-ecologicos en la conservacion y demostraran como los estudios interdisciplinarios pueden revelar datos revolucionarios.
