When the time is right, a good love song can make all the difference. A study from the University of California, Davis, found that temperature affects the sound and quality of male frogs’ mating calls. In the colder, early weeks of spring, their songs start off sluggishly. In warmer weather, their songs pick up the pace, and female frogs take note. Better songs make the males more attractive mates and suggest to females that conditions are suitable for reproduction. …The results carry implications for conservation amid climate change. …Understanding when frogs breed, how that may shift as the climate warms, and what is driving those shifts is critical to their conservation. …females do not necessarily come to the pond just because the males are calling. The time has to be right for her eggs to survive. That clue lies in the quality of the male’s song, which is more attractive once it’s warmer.
