The best way for scientists to share their research is to publish it in scientific journals. This can be a lengthy process, so it’s always very exciting when your work is finally published. We’re so excited that we wanted to share some of our recent publications with you.  Click the links below for the abstract (or to download the paper if you’re a fancy pants scientist/academic with access!)

We’ve also had a whole bunch geographic distribution notes published in the journal, Herpetological Review. That usually means we observed a species outside of its known range. We had four notes in September’s Issue and seven in December’s issue. Authors from our lab included Chris, Brad, Gail, Sean (lab alum), and undergrads Mark Herr, Mark Goldy-Brown, and former intern Jennie Williams. Pretty cool!

If you missed our recent posts about some of these topics, be sure to read more about tadpole boldness, lizard cannibalism, and bearded ladies!
