081 Is that even a frog?

Frogs come in all shapes and sizes, but some frogs are particularly odd. Rain frogs with their globus bodies are the topic for this episode. Why are they living with mole-rats? And what do people living side-by-side with them think? Species of the Bi-week is a fresh rain frog, with remarkable colour variation.

080 Genetics to the Rescue

Hello 2021! We are back and this time discussing genetic rescue - can isolated, dwindling populations be assisted by adding individuals from elsewhere? After that, our Species of the Bi-Week has a dewlap but it isn't an anole.
