Abstract

Objective: The objective of this work is to verify whether these factors influence the hatching of Amazon turtle eggs in this region. Method: For this, data from reproductive periods during the years 2013 and 2019 were used within the selected areas. Only the depth of the nests was related to the total number of eggs, on both beaches, in both years, and with the number of eggs hatched, only on Praia da Saudade in 2013. Results and Conclusion: In 2019, Praias da Saudade and Thaís showed differences between incubation temperature, percentage of finer grains in the sand, distance from vegetation to nests and hatching rate. However, none of the evaluated parameters were related to reproductive success. Factors such as the incubation period, the amount of clay in the sand and the percentage of riverine vegetation may also be possible predictors of reproductive success that should be investigated.
