Resumen
Se realizó un análisis de los factores asociados a actividades y anidación de tortugas marinas en las playas Nancite y playa Naranjo del Parque Nacional Santa Rosa (PNSR), para comprender cuáles factores afectan en mayor medida la anidación de tortugas. Se abordo los factores asociados a la depredación de tortugas marinas por jaguar, esto con el propósito de comprender mejor la relación depredador-presa y cuál es el factor más influyente para que este fenómeno suceda. La investigación se realiza con el propósito de identificar los factores que influyen en la distribución de carcasas de tortugas, así como una comparación entre playas con diferentes niveles de apertura al público. Se analizó los datos espacial de carcasas mediante el sofware Qgis versión 2.18, (Qgis-core development team), con el cual se elaboró mapas de calor mediante el método de Kernel, para esta investigación consideré puntos calientes (hotspots) a sitios con mayor abundancia de carcasas de tortugas marinas por unidad de área.
An analysis of the factors associated with activities and nesting of sea turtles was carried out on the Nancite and Naranjo beaches of the Santa Rosa National Park (PNSR), to understand which factors affect the nesting of turtles to a greater extent. The factors associated with the predation of sea turtles by jaguars were addressed, this in order to better understand the predator-prey relationship and what is the most influential factor for this phenomenon to happen. The research is carried out with the purpose of identifying the factors that influence the distribution of turtle carcasses, as well as a comparison between beaches with different levels of openness to the public. Carcass spatial data was analyzed using the Qgis software version 2.18, (Qgis-core development team), with which heat maps were drawn up using the Kernel method, for this research I considered hot spots (hotspots) to sites with greater abundance of sea turtle carcasses per unit area.
