Climate change a likely culprit in coqui frog's altered calls, say UCLA biologists
Date:4/14/2014

Changes in the Puerto Rican climate over the past three decades have caused small but significant changes to the coqui frog, the territory's national animal. UCLA biologists have found that not only have male coquis become smaller, but their mating call has also become shorter and higher pitched.

Authored by Peter Narins, UCLA distinguished professor of integrative biology and physiology and of ecology and evolutionary biology, and Sebastiaan Meenderink, a UCLA physics researcher, the study examined 170 male coqui frogs (Eleutherodactylus coqui) in 1983 and then 116 males in 2006. The study included frogs found at 28 altitudes in Puerto Rico, ranging from about 10 yards above sea level to more than 1,100 yards above sea level.

The study, the first to show the effect of temperature change on a species of frogs in the tropics over a period of more two decades, was published online April 9 in the journal Proceedings of the Royal Society B, and will appear later in the print edition.

"We think the animal adapted to temperature change by becoming smaller, which we believe causes the differences in their calls," said Meenderink, who was previously a postdoctoral scholar in Narins' laboratory. The male's call is significant because it is used to attract females and to defend territory from other males.

Narins, who has studied the coqui for 41 years, said although the change is not very large, it is statistically significant and may well be a sign of difficult years ahead for the animal. The coqui is so beloved in Puerto Rico that it is the subject of songs and children's stories there.

Now, because of climate change, its reproductive success is likely to decrease substantially, the scientists predict.

"If current trends continue unabated, the coqui frog will sound and look quite different before this century is over," said Narins, a faculty member in the UCLA College of Letters and Sci
