In a concerning environmental trend, researchers have noted a substantial decline in the nesting of green sea turtles (Chelonia mydas) on the island of Fernando de Noronha, with only ten nests identified up to this date compared to a staggering 451 nests during the same period last year. This decline raises alarms among researchers and conservationists because the green sea turtle typically begins its reproductive season at the end of the year, and such a drop in nesting numbers is unprecedented in recent history.

Rafaely Ventura, the coordinator of the Tamar Project Foundation, mentioned that the team is investigating the various factors contributing to this decline, noting that this issue is not unique to Fernando de Noronha; similar patterns have been observed in other areas of the Southern Atlantic, including Trindade Island and the Rocas Atoll. Researchers are currently exploring different hypotheses to understand the causes behind this decrease, particularly in light of the previous season, which had seen a record number of nests - 805 in Fernando de Noronha, the highest in over 40 years of monitoring.

The apparent drop in sea turtle nesting is alarming not only for local ecosystems but also for conservation efforts in Brazil, which had previously celebrated a record number of nests indicating a healthy population of these endangered species. Continued monitoring and research are crucial in understanding this trend, ensuring informed actions can be taken to protect the sea turtles in the region, especially as they face numerous threats from human activity and changing environmental conditions.
