Back to the news niche! This fortnight we’re talking about a collection of papers ranging from crocodile colours to frog personalities, as well as the mysterious death of a tortoise. We finish up with a meta-chat about science podcasting and a brief mention of the crazy future world of in-field laboratories. FULL REFERENCE LIST AVAILABLE AT: herphighlights.podbean.com

Long-time friends of herpetologists, anoles have proven a fruitful area of research for decades. This bi-week we discuss a couple of papers examining anole behaviour and colouration before highlighting a newly discovered (and rather spectacular) species.

We back for another invertebrate versus amphibian episode. But this time we’re focusing on carabid beetles and their relentless consumption all amphibian life. They have managed to turn the tables on their would be predator in a remarkable case of role-reversal. Species of the Bi-week is a beautiful frog with a fittingly macabre name. FULL REFERENCE LIST AVAILABLE AT: herphighlights.podbean.com

This bi-week we decided to do things a little differently. No main theme, we just read random stuff and chatted about it. Featuring some exciting new developments in the crab vs snake continuum, and some methodological issues to keep an eye on.

We kick off this episode with the announcement of our move onto Patreon: https://www.patreon.com/herphighlights . Research chat this time is all British snakes. We may not have the most extensive array of snake-life in the Britain, but that doesn't mean that there can’t be some exciting herpetofaunal research. This fortnight we are looking at a couple of papers on smooth and grass snakes. And a slight change to the Species of the Bi-week. FULL REFERENCE LIST AVAILABLE AT: herphighlights.podbean.com
