This article from phys.org is interesting. A 17-year study of loggerhead sea turtles in Cabo Verde reveals a surprising twist: as oceans warm, females are nesting earlier and beaches appear busier than ever, yet each turtle is actually producing fewer clutches and fewer eggs over her lifetime. The research team from Queen Mary University of London and Associação Projeto Biodiversidade tracked individual turtles over nearly two decades and found that while warmer seas speed up nesting and shorten the time between nests within a season, they also coincide with longer gaps between breeding seasons and a decline in overall reproductive output.
The article goes beyond the beach to show how climate change is quietly reshaping life offshore, where these “capital breeder” turtles must build up energy reserves in increasingly less-productive feeding grounds before returning to lay eggs. By linking satellite data on ocean productivity with detailed nesting records, the study shows that food availability at distant West African foraging sites now strongly dictates how often turtles can breed and how many eggs they can afford to lay—posing new challenges for conservation strategies that focus only on nesting beaches.
