☆ Amphibians Are the World's Most Vulnerable Species and Threats Are Increasing

A new global assessment has found that 41% of amphibian species that scientists have studied are threatened with extinction, meaning they are either vulnerable, endangered or critically endangered. “Amphibians are the world's most threatened animals,” said Duke University's Junjie Yao, a frog researcher who was not involved in the study. But a growing percentage of amphibian species are now also pushed to the brink by novel diseases and climate change, the study found. The study identified the greatest concentrations of threatened amphibian species in several biodiversity hotspots, including the Caribbean islands, the tropical Andes, Madagascar and Sri Lanka. Other locations with large numbers of threatened amphibians include Brazil’s Atlantic Forest, southern China and the southeastern United States.

☆ Glass act: Scientists reveal secrets of frog transparency

Their delicate, greenish transparent forms don’t cast shadows, rendering them almost invisible to birds and other predators passing overhead or underneath. But when northern glass frogs wake up and hop around in search of insects and mates, they take on an opaque reddish-brown color. “When they’re transparent, it’s for their safety,” said Junjie Yao, a Duke University biomedical engineer and study co-author. A male glass frog photographed from below using a flash, showing its transparency. “Transparency is super rare in nature, and in land animals, it’s essentially unheard of outside of the glass frog,” White said.
