SUMMARY:

In the present work, the reproductive ecology of nesting and the conservation history of the species of Podocnemis expansa were studied in a floodplain area called Ilha do Meio, in the lower Amazon River, West of Pará – Brazil. This island environment can be considered atypical for nesting, among others, because it is located on the bed of the Amazon River, a highly navigable region with intense movement of vessels, which suffers natural erosion, natural and anthropogenic predation. The site was monitored between October 2021 and January 2022, covering the stages of nesting, incubation and hatching/emergence of chicks. The nests were deposited in an area with fine grain size, at an average distance of 52.3 cm from the vegetation, an average final depth of 28 cm (±5.72 N=30) and an average of 97 eggs. Turtle mortality has been recorded due to burial, boat propeller accidents and exhaustion from physical exertion combined with excessive heat. The nests established in the nesting area were 100% flooded due to the low terrain and early onset of rain. This is the first work evaluating reproductive aspects of P. expansa on Ilha do Meio and may be the initial step towards understanding the existence and permanence of the chelonian population in this study area. The information presented here is part of the conservation protocol for the species P. expansa at the Ilha do Meio breeding site, which is published.
