Green poison-dart frog varies mating call to suit situation
Date:11/11/2013

ale was near and they became as vocal as red males. In the right context, when mating opportunity is certain, green males appear to trade-off the risk of predation for the mate-securing benefits of bold behavior.

"Our results support the notion that populations of phenotypically or observably different divergent species may use different solutions to the trade-off between natural and sexual selection, by adjusting the place and time of displays to risks and opportunities," says Willink. "In poison frogs this may have contributed to the dramatic variation in color pattern conspicuousness observed across species."
