Global Warming Drives Amphibian Sex Reversal and Extinction Risks

A warming climate is increasing the frequency of sex reversal in animal species, where genetic females develop into fertile males, threatening population growth and genetic diversity.

Researchers studying agile frogs in Hungary published findings in Science Advances on September 3 showing that sex-reversed wild males sire fewer offspring.

The study revealed that 61 percent of offspring from sex-reversed male frogs also underwent sex reversal, heightening vulnerability to heat and infectious diseases.
