Fluorescing frogs (toadlets) and glowing geckos are topics of discussion this episode. We dig into the whys and ecological context of glowing, but really there remains a lot to learn.

087 Invasion Evasion

Frogs: invasive menace, and victim. We look at two papers showing how frogs are faring in the face of human-caused species invasions. One where the frog is the invader, another where the frogs are facing down a novel threat –mongooses. Species of the Bi-week is a wee salamander from Japan.

083 Humans and Venom

Humans and snakes share a long and storied past. In this episode we examine one paper that looks at the prehistoric relationship between humans and cobras (namely their spitting), and a second that looks at how we can mitigate the negative impacts of this relationship today. Our stunning Species of the Bi-week looks to be covered in duck-weed.

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.
