The northern Great Barrier Reef, the site of the overwhelming female population, has one of the largest populations of green sea turtles in the world, the study said.
Biologists consider 84.74 degrees Fahrenheit to be the pivotal temperature for green sea turtles to be born a mixture of female and males.
The sex of green turtles is influenced by temperatures during their incubation period and a difference of just a few degrees in the temperature of nests - which are dug into beaches - can result in a population that is 100% male or female.
"Finding that there are next to no males among young northern green turtles should ring alarm bells, but all is not lost for this important population". Majority of sea turtles from warmer northern beaches, on the other hand, were female, with 86.8 percent of adult turtles, 99.8 percent of sub-adult turtles and 99.1 percent of juvenile turtles turning out to be female.
"This is extreme-like capital letters extreme, exclamation point extreme", Camryn Allen, a National Oceanic and Atmospheric Administration (NOAA) endocrinology researcher and the study's co-author, told National Geographic. "With average global temperature predicted to increase 2.6°C by 2100 many sea turtle populations are in danger of high egg mortality and female-only offspring production".
Environment temperatures play a key role in determining the sex of green turtles.
For many reptiles, sex is determined not by chromosomes, but by the temperature at which their eggs are incubated.
"These results suggest that increased sand temperatures affect the sex ratios of the (northern Great Barrier Reef) population such that virtually no male turtles are now being produced from these nesting beaches", the study said. Green sea turtles are protected under the Endangered Species Act and listed as endangered on the International Union for the Conservation of Nature's Red List.
The researchers found that a gathering of turtles in the cooler southern piece of the reef were 65 to 69 percent female while a gathering from the water northern piece of the reef skewed considerably more female.
"Realizing what the sex proportions in the grown-up reproducing populace are today, and what they may look like five, 10 and quite a while from now when these youthful turtles grow up and move toward becoming grown-ups, will be extraordinarily profitable". "We know that species evolve in response to climate and other environmental changes, but they need time for that".
