What reason caused sea turtles were all females in Florida in past four years?
Climate change causes sex ratio imbalance in new-born sea turtles off Florida coast: all females in past four years.
In recent years, extreme weather events have occurred frequently around the world, and many countries have continued to experience heat waves.
As a result of the warmer beach temperatures in Florida, scientists say nearly all of the newborn sea turtles on the beaches in the past four years have been female.
According to the British “Guardian” report on August 4, according to a study by the National Oceanic Administration of the United States, if the turtle eggs hatch in an environment below 27°C, they are more likely to be male; and if they hatch at temperatures above 31°C , the baby turtles will be born mostly female.
If the temperature oscillated between these two figures, the hatchlings were born with both males and females. The researchers also found that the warmer the sand, the higher the proportion of female turtles.
“As the planet’s climate changes, warmer temperatures may skew hatching conditions, even fatal, which will affect sea turtle species as well as other reptiles,” the US National Oceanic Administration said.
“It’s frightening that the past four summers in Florida have been the most The hottest summers.” She added, “Scientists studying turtle larvae and eggs have found no males, only females, in the past four years.”
The growing gender imbalance is causing concern among scientists, who fear it will eventually threaten the reproduction and survival of sea turtle populations.
And at the recently opened turtle hospital at the Miami City Zoo, turtle breeder Melissa Rosales Rodriguez told Reuters, “You’ve seen their numbers decline dramatically over the years because of their lack of genetic diversity… …We are not reaching the sex ratios needed for successful reproduction.”
In addition to facing an increasing number of female turtles, the Turtle Hospital is currently working to address Turtle Fibromastoidoma.
This is a potentially fatal disease in which tumors can form in the eyes, mouth or internal organs of diseased turtles. Zickelbach called for more turtle hospitals to open, saying “there’s a need across Florida.”
