Recovery of green turtle populations and their interactions with coastal dune as a baseline for an integral ecological restoration
Background and Aims: Ecological restoration has focused on the physical and vegetation components of ecosystems, leaving aside studies on wild fauna and their interactions.

| description | Background and Aims: Ecological restoration has focused on the physical and vegetation components of ecosystems, leaving aside studies on wild fauna and their interactions. Chelonia mydas is an endangered macroherbivore that nests on sandy beaches of Mexico and Cuba, and influences the coastal vegetation with organic matter contributions. The objectives of this study were to analyze its population recovery, a greenness index for dune vegetation, and the amount of organic matter estimated from its clutches before and after the implementation of an official Mexican norm.
Methods: Biological data obtained from two and three decades of monitoring 16 Chelonia mydas nesting beaches were analyzed; based on these, three levels of demographic indexes were carried out, the contribution of organic matter by marine turtles to the beach and the vegetal vigor using remote sensing, besides implementing the pertinent statistical analysis.
Key results: There was an exponential increase of the green turtle nests (between 12 and 14% per year), associated with population recruitment pulses in 2000 and 2008. The contribution of organic matter to the beach was significantly higher after a change in clutches management in Mexico, and an increase in the dune vegetation greenness was detected in high Chelonia mydas nesting zones.
Conclusions: The increase of the green turtle populations invites to reflex about the implications of the recovery of species of fauna have on other communities in the ecosystems they inhabit, demanding the analysis of the actual paradigms and the adaptation strategies that attend their management needs, procuring the ecological integrity conditions of their habitats. |

Antecedentes y Objetivos: La restauración ecológica se ha centrado en los componentes físicos y vegetales de los ecosistemas, y ha dejado de lado a la fauna silvestre y sus interacciones. Chelonia mydas es un macroherbívoro en peligro de extinción que anida en playas de México y Cuba, e influye en la vegetación costera con aportaciones de materia orgánica. Los objetivos de este estudio fueron analizar su recuperación poblacional, un índice del verdor de la vegetación de duna, así como la cantidad de materia orgánica estimada de sus nidadas antes y después de la implementación de una Norma Oficial Mexicana. Métodos: Se analizaron datos de entre dos y tres décadas de monitoreo biológico en 16 playas de anidación de Chelonia mydas; a partir de ellos se realizaron tres niveles de análisis de indicadores demográficos, la aportación de materia orgánica de las tortugas en la playa y el vigor vegetal a partir de sensores remotos, además de aplicar los estadísticos pertinentes. Resultados clave: Hubo un crecimiento exponencial del número de anidaciones de tortuga verde (entre 12 y 14% anual), asociado con pulsos de reclutamiento poblacional en los años 2000 y 2008. El aporte de materia orgánica a la playa fue significativamente mayor después de un cambio en la estrategia para manejo de las nidadas en México, y se detectó un incremento en el verdor de la vegetación de duna en zonas de anidación alta de Chelonia mydas. Conclusiones: El incremento de las poblaciones de tortuga verde lleva a reflexionar acerca de las implicaciones que tiene la recuperación de especies de fauna sobre otras comunidades en los ecosistemas que habitan, lo que demanda el análisis de los paradigmas actuales y la adaptación de estrategias que atiendan sus necesidades de manejo, procurando las condiciones de integridad ecológica de sus hábitats.
