Introduction: Lepidochelys olivacea is the most abundant sea turtle in the Colombian Pacific and oceanographic conditions at the Eastern Tropical Pacific may have an effect on its reproductive behavior Objective: To assess the relationship between reproductive aspects of L. olivacea nesting at Gorgona island and sea surface temperature at local and regional scales. Methods: Monthly mean data of reproductive attributes associated with nesting females, nests, eggs and hatchlings were established using records from Gorgona’s National Natural Park nesting monitoring and were correlated (cross-correlations) with SST of Gorgona island and Panama Bight, and with the temperature variability of the El Niño 1+2, El Niño 3, El Niño 3.4 and El Niño 4 regions, their thermal anomalies, and the ONI and SOI indexes. Significant correlations were included in a Generalized Additive Model. Results: Highest inverse correlation since maximum correlation is 1 was established between visits to the beach, number of nesting females, number of nests, clutch size, incubation days and hatching success and Niño 1+2 region with a lag of 12 months, whereas egg diameter, egg weight, straight carapace length and width and weight of hatchlings were correlated with Niño 4 anomaly, SOI and ONI indexes. It was also found that there is a non-linear tendency to decrease number of nesting females, number of nests, clutch size, egg diameter and egg weight with regional positive anomalies. Conclusions: Nesting attributes of L. olivacea in Gorgona correlate mainly with variations in regional SST, being low at high sea surface temperatures the year prior to nesting (12-month lag). |

Objetivo: Evaluar la relación entre los aspectos reproductivos de L. olivacea anidantes en isla Gorgona y la temperatura superficial del mar a escala local y regional. Métodos: Se estableció la información promedio mensual de los atributos asociados con las hembras anidantes, nidos, huevos y neonatos utilizando los registros del monitoreo de anidación del Parque Natural Nacional Gorgona y se correlacionaron (correlación cruzada) con las regiones El Niño, sus anomalías, los índices ONI y SOI (escala regional) y la temperatura superficial del mar de la Ensenada de Panamá y las aguas de Gorgona (escala local), luego las correlaciones significativas se incluyeron en modelos aditivos generalizados. Resultados: se estableció una correlación inversa máxima entre las visitas a la playa, el número de hembras anidantes, el número de nidos, el tamaño de las nidadas, los días de incubación y el éxito de eclosión y la región Niño 1+2 con un rezago de 12 meses, mientras que el diámetro y el peso de los huevos, el largo y ancho del caparazón y peso de los se correlacionaron con la anomalía de Niño 4 y los índices SOI y ONI. También se encontró que existe una tendencia no lineal a disminuir el número de hembras anidantes, número de nidos, tamaño de nidadas, diámetro y el peso de los huevos con anomalías regionales positivas. Conclusión: Los atributos de anidación de L. olivacea en Gorgona se correlacionan principalmente con las variaciones en la temperatura superficial del mar regional, siendo bajos a temperaturas altas en el año anterior a la anidación (rezago de 12 meses).
