221 Salamander Salvation
Tuesday Feb 18, 2025
Tuesday Feb 18, 2025
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.

220 Toxic Toads A Tale of Two Species
Friday Feb 07, 2025
Friday Feb 07, 2025
The Asian common toad (aka Asian black-spined toad, Asian toad, black-spectacled toad) is a remarkably successful species, living alongside humans and colonising new lands. A new study suggests there might be more than meets the eye, with the toads being more than one species. We finish with a newly described tiny species of chameleon from Madagascar.

219 Ball Pythons Care About Friendship
Tuesday Jan 28, 2025
Tuesday Jan 28, 2025
Our understanding of the social lives of snakes is evolving at breakneck speed. This week we discuss a new study which has revealed that ball pythons have social behaviour. We also talk about sociality in rattlesnakes, before moving on to some news from the world of milk snake speciation - there may be fewer species than previously thought.
