Could a dry spell threaten the future of sea turtles? Major arribadas of Olive Ridley turtles are gracing the shores of Ocional, Guanacaste, but a looming threat could change these iconic scenes. Experts warn that the El Niño phenomenon and rising temperatures pose significant risks to nesting sea turtles.
High temperatures can directly impact nesting success. When sand becomes too dry, nests can collapse, and developing eggs may reach lethal temperatures. This is particularly concerning as recent dry spells have extended beyond the typical dry season, potentially dooming many nests.
Furthermore, El Niño can disrupt the turtles' migration patterns. Changes in ocean conditions and food availability might force them to alter their return periodicity, leading to fewer turtles nesting in the coming years. The survival of current nests hinges on rainfall in the coming weeks.
