025 Return of the Invertebrates
Tuesday Apr 17, 2018
Tuesday Apr 17, 2018
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.

024 News Niche - Crabs and p-values
Tuesday Apr 03, 2018
Tuesday Apr 03, 2018
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. Huge thank you to our Patreons - if you enjoy the podcast please consider donating at www.patreon.com/herphighlights
