Most sea turtles now female in northern Great Barrier Reef
It’s feared that some turtle species will be wiped out because not enough males are being born
09 January, 2018, 14:40
Scientists researching the impact of climate change on one of the world's largest sea turtle populations have found that turtle eggs, laid on warmer beaches along the north-east coast of Australia, can produce animals nearly entirely of the female gender.
The results, which were determined through non-fatal genetic testing and endocrinology, show that a 99.1 percent female bias exists in the hotter northern region.
"Furthermore, extreme incubation temperatures not only produce female-only hatchlings but also cause high mortality of developing clutches", the study said.
"The most important thing is for Australia and the rest of the world to set ambitious targets to reduce emissions and bring global warming under control". With rising temperatures, no more males would be around to mate with females, which could ultimately crash the whole population of sea turtles. Around 65-69 percent of turtles coming from beaches in the Southern Great Barrier were discovered to be female.
"It is deeply concerning, because if it continues we're going to start to lose the male population, [which is] essential for breeding and keeping those populations sustainable in one of the world's most important green turtle populations", said WWF Australia chief Dermot O'Gorman.
Scientists believe the northern Great Barrier Reef rookeries have been producing primarily females for more than two decades.
