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

Unsurprisingly, water snakes love water. But what happens when this precious resource dries out? This week we discuss the effects of drought on various American water snakes, and pay homage to a newly described Mesoamerican snake. FULL REFERENCE LIST AVAILABLE AT: herphighlights.podbean.com
