Some tree-dwelling salamanders have a remarkable ability to ‘sky-dive’, controlling their descent after leaping away from predators. New research tests the gliding ability of a number of different species, and finds that some are more adept than others. We follow up with a brand new frog species described from Kangaroo Island, Australia.

We are talking about our own work this week, focusing on our latest research into Europe’s foremost colubrid, the Aesculapian snake. We chat about radio-tracking these beasts and dive into some of the media coverage this study has received. Finally, we touch on some good conservation news from the Zoological Society of London.

Salamanders and frogs return to their home pools to breed, but removal of these pools is making life more difficult for them. New research discovers how artificial pools can affect the genetics and fates of both spotted salamanders and wood frogs.
