In this episode we gently debate subspecies, and then dive into several snake papers, from their anomalously extensive and rapid diversification, to a recent taxonomic change. Regrettably the audio on this episode was affected by a technical error, so it is far less than our usual quality (Ethan and Hiral are a little quiet, sorry!). Hopefully it doesn’t affect the listening experience too badly!

Here’s episode 18, a Works in Froggress episode, featuring the Mates, Dr Mark D. Scherz, Gabriel Ugueto, and Ethan Kocak, talking about what’s going on in their new lives stuck inside—Ethan’s setting off on a freelancing lifestyle, Gabriel has been tweaking the same illustration forever, and Mark is working on FIIIIIIIIIISH! The Mates then dive into a discussion about Uroplatus geckos!

A note: this episode was recorded on the 24th of April 2020, a time when most of humanity seemed united in their fight against a common enemy, the coronavirus COVID-19. In the meantime, another enemy of humanity has been brought into the limelight that, by its very nature, divides. That enemy is racism. The experiences of Christian Cooper highlight how people of colour may be treated when engaging in field sciences like ornithology or herpetology, and similar stories are being heard from people of colour across social media (e.g. see the #BlackInNature tag on twitter). We must strive to make field-based sciences like herpetology inclusive of people of colour, and to fight racism wherever we encounter it in order to disassemble the systematic discrimination that plagues our fields and our societies. We at the SquaMates podcast stand firmly behind the BlackLivesMatter movement.

The post SquaMates Ep. 18: Amici manere domi! first appeared on SquaMates.

We’re back with Episode 17! In this Breaking Newts episode, the Mates, Dr Mark D. Scherz, Gabriel Ugueto, and Ethan Kocak, talk about the coolest new research in herpetology and Gabriel’s extremely squeaky chair! Featuring a few controversial new bits of science, some amazing turtles, diverse salamanders, and glowing, bony amphibians!

A note: this episode was recorded on the 24th of April 2020, a time when most of humanity seemed united in their fight against a common enemy, the coronavirus COVID-19. In the meantime, another enemy of humanity has been brought into the limelight that, by its very nature, divides. That enemy is racism. The experiences of Christian Cooper highlight how people of colour may be treated when engaging in field sciences like ornithology or herpetology, and similar stories are being heard from people of colour across social media (e.g. see the #BlackInNature tag on twitter). We must strive to make field-based sciences like herpetology inclusive of people of colour, and to fight racism wherever we encounter it in order to disassemble the systematic discrimination that plagues our fields and our societies. We at the SquaMates podcast stand firmly behind the BlackLivesMatter movement.

Nature, 579:245–249. 10.1038/s41586-020-2068-4 — Darren Naish has done a great job of first writing about this in its original interpretation, and then updating his article to explain the ethical and phylogenetic problems associated with the paper. On the 29th of May, 2020, an editor’s note was added to the paper, that reads ‘Readers are alerted that doubts have been expressed about the phylogenetic placement of the fossil described in this paper. We are investigating and appropriate editorial action will be taken once this matter is resolved.’

The post SquaMates Ep. 17: Malayopython and the Glowing Tail first appeared on SquaMates.

Episode 16 is here, in this episode we—Dr Mark D. Scherz, Gabriel Ugueto, and Ethan Kocak—feature an interview with Professor Emily Taylor of Cal Poly, and two of her students, Isabelle Barnes and Katie Rock, talking about their amazing dataset about sex biases in publishing in herpetology, recorded at the 9th World Congress of Herpetology in Dunedin, New Zealand.

Episode notes sometimes get clipped on your device or by your podcast provider; for full (extensive) notes (and references), go to http://www.squamatespod.com

For more information about the dataset we talk about, check out Professor Taylor’s tweet about it here, but most importantly, read the detailed blog post about it here. We were thrilled to be able to interview this team, and will update this post when the data are published.
