James Crouch Lecture

Dr. Chelsea Specht (Associate Professor, University of California, Berkeley) gives SDSU’s first James Crouch Lecture on Monday, May 9th 2016: “PETALOIDY AND POLLINATION: THE EVOLUTION OF FLORAL FORM IN THE ZINGIBERALES.” A fantastic mix of phylogeny, molecular evolution, a comparative morphology! We had a chance to visit the Torrey Pines State Reserve with Dr. Mike Simpson.

Elliott Kennerson reports on ‘The Bombardier Beetle And Its Crazy Chemical Cannon‘ for KQED Science’s Deep Look program. Learn about the bombardier beetle, what we know about it’s explosive chemistry, and some of our hypotheses as to how this system may have evolved. Collaborator Dr. Kip Will (UC Berkeley) stars in this video (alongside the bombardier Brachinus)!

‘Beetling’ in Southern Arizona

Tanya visits with Wendy Moore’s lab at the University of Arizona for some ‘beetling’ in the eastern foothills of the Santa Catalina mountain range for our collaborative NSF project. Our goal was to find some quinone-producing Chlaenius and the bombardier beetle Brachinus. Pictured: Reilly McManus (Moore Lab, U. Arizona) holds up a vial of Chlaenius near the edge of a stream, rimmed with loose rocks. The perfect habitat for these beetles.

Feature on Carnivorous Plants

The Renner Lab provided content related to carnivorous plants and their digestive fluid for Atlas Obscura‘s article featuring man-eating plant myths: “Once the idea of a giant, flesh-eating plant enters the imagination, it can be hard to dislodge. Imagine this: you’re in the jungle, and you discover a plant with surprisingly large, tentacle-like leaves. The clearing is full of a heavy, sweet smell. Maybe there’s an animal skeleton under the plant. Did the leaves move? Was that just the wind? You move closer, and the plant seems to yearn towards you….” Read the full article on Atlas Obscura’s webpage.

Dr. Ulrike Bauer Visits The Renner Lab

We were very lucky to have Dr. Ulrike Bauer visit the laboratory the past 10 days to collaborate on a Nepenthes transcriptome project. On October 26th, she gave a wonderful departmental seminar ‘Springboards, water slides and sticky pools – How carnivorous pitcher plants catch their food’. Dr. Ulrike’s research uses carnivorous plants as a model to investigate mechanical defense strategies of plants. Her work combines the study of functional plant morphology with elements of biomechanics, ecology and developmental biology to address both ecological and evolutionary questions. I invite you to read about her current research that was featured on BBC.com this October (http://www.bbc.com/news/science-environment-34414284) and to watch a short video (http://tinyurl.com/ndt3o2b). Of course, between lab work and brainstorming, we had to visit some great San Diego wilderness areas.

Collaborative research featured on BacterioFiles Podcast

Our collaborative research (with Kevin Hockett and David Baltrus, U. Arizona) was featured on a recent BacterioFiles Podcast: “Bacteria have repeatedly captured and used the tails of phages to fight each other!” Listen to us talk about the Independent Co-Option of a Tailed Bacteriophage into a Killing Complex in Pseudomonas.

Carnivorous Plant Research Featured on BBC Earth

BBC Earth article “Giant Plants that Eat Meat”, presented by Cat Adams/BBC Campus, examines pitcher plant morphology, digestive enzymes, and unique associations with mammals. Tanya Renner’s research of carnivorous plant digestive enzymes and their similarity to plant defense proteins are featured. Read the article here
