Australian researchers are applying a sex hormone to the skin of the critically endangered northern corroboree frog in a world-first treatment to encourage females to accept less desirable mates in captivity.
A trial conducted by the University of Wollongong and Taronga zoo found that, by administering the hormone to both a male and female frog before pairing them off, researchers could increase the chance that they would accept their allocated partner from about 22% to 100%.
In a world-first, the researchers put a few drops of the synthetic gonadotrophin-releasing hormone on the frog’s stomach instead of using the accepted technique of injecting the hormone under the skin. MORE
