'Frog song' may help understand climate change

Jayashree Nandi in the Times of India: If not kissing the frog, at least appreciating their 'croak' may lead to some headway in to climate research . For the first time frog song is being monitored using automated sound recorders by Indian scientists to track the impact of climate change on amphibians in the forests of southern Western Ghats. The methodology for tracking their call has recently been standardized by researchers.

Principal investigators of the study were struck with the idea when three of them were 100 feet above the ground on a rainy day, sitting on a tree shelter for canopy research at Kalakad Mundanthurai Tiger Reserve. They heard frog song and decided to investigate how it could relate to climate.

Since frogs and toads respond to changes in atmospheric moisture and temperature, the team decided on analysing the sound recordings of frog song and corelate it with readings from climate data loggers.

"Amphibians have long been considered to be the barometers of the climate any subtle variations in the atmospheric conditions like moisture availability and temperature is likely to have profound impacts on them' said Seshadri.KS, who is heading the project and is part of the team that won the Conservation Leadership Programme-Save Our Species with senior fellow at Ashoka Trust for Research and Ecology, Ganesh T...
