Caracterización de los sitios de anidación de tortugas marinas en la playa de Cojimíes, Pedernales Ecuador, septiembre 2023 a abril del 2024.

Abstract

The study analyzed the nesting conditions of sea turtles on Cojimíes Beach, Manabí, Ecuador, during the season from September 2023 to April 2024. Activities included patrols to identify nesting tracks, nest monitoring, sand texture analysis, and temperature measurements in the nests. Additionally, at-risk nests were relocated, and protective measures using handmade mesh screens were implemented to prevent predation. Natural and human threats, such as pollution and the presence of predators, were also identified. The results revealed variable hatching rates, ranging from 35.1% to 100%. Nests located in protected areas showed higher success rates, while those near the tide line were at greater risk of flooding. The predominant fine sand (200-500 microns) and stable temperatures between 27.1 °C and 29.0 °C were ideal for incubation. Regarding hatchlings, carapace lengths ranged between 35 mm and 45 mm, with an average of 40 mm, reflecting favorable conditions during embryonic development. In conclusion, although Cojimíes Beach offers optimal conditions for nesting, it faces significant threats that compromise reproductive success. It is crucial to implement comprehensive strategies, such as tourism management, predator control, and pollution reduction, to conserve sea turtle populations in the region.
