Turtle Troubles

No New Males: Climate Change Threat to Cape Verde Turtles,
University of Exeter, July 11, 2019.


Hot End of Loggerhead Turtles
"...by 2100 - more than 90% of loggerhead nests on the Cape Verde islands could incubate at "lethally high temperatures", killing turtles before they hatch."

Turtle Troubles
"The sex of turtle hatchlings is determined by incubation temperature..."

Low Heat Not Happening…
"Even under a scenario based on low future emissions and warming, by 2100 just 0.14% of hatchlings would be male."

"Under mid and high-emissions scenarios, hatching of male loggerheads could cease entirely."

Nearing the End
"We estimate that 84% of current hatchlings are female, and warmer temperatures will increase this proportion."

How Long the End?
"It is not clear how long it will take the population to decline if males stop being produced, as the reproductive lifespan of males is not known - so older males may continue breeding for many years after new males stop being hatched."
