During our seven years living and working in the Western Ghats we came to appreciate frogs through the eyes of our family, those of our staff, as well as travelers and occasional scientific references (the man on the left in the photo to the left having shown up in our pages one of those times). Good to know that the science is being shared for good cause, thanks to Anne J. Manning in this article for the Harvard Gazette:

Who will fight for the frogs?

Having pulled themselves from the water 360 million years ago, amphibians are our ancient forebears, the first vertebrates to inhabit land.

Now, this diverse group of animals faces existential threats from climate change, habitat destruction, and disease. Two Harvard-affiliated scientists from India are drawing on decades of study — and an enduring love for the natural world — to sound a call to action to protect amphibians, and in particular, frogs.

Sathyabhama Das Biju, the Hrdy Fellow at Harvard Radcliffe Institute and a professor at the University of Delhi, and his former student Sonali Garg, now a biodiversity postdoctoral fellow at Harvard's Museum of Comparative Zoology, are co-authors of a sobering new study in Nature, featured on the journal's print cover, that assesses the global status of amphibians. It is a follow-up to a 2004 study about amphibian declines.

Biju and Garg are experts in frog biology who specialize in the discovery and description of new species. Through laborious fieldwork, they have documented more than 100 new frog species across India, Sri Lanka, and other parts of the subcontinent.

According to the Nature study, which evaluated more than 8,000 amphibian species worldwide, two out of every five amphibians are now threatened with extinction. Climate change is one of the main drivers. Habitat destruction and degradation from agriculture, infrastructure, and other industries are the most common threats to these animals.
