Welcome to Teacup Rex

I can’t remember a time when I wasn’t fascinated and inspired by the natural world. Now, as an ecologist, science educator, and illustrator, I strive to inspire others with a similar love and appreciation for science.

Fairfield Osborn Field Trip

I had a super fun time today doing something old, and something new! For the first time, I took some of my College of Marin students on an actual off-campus field trip, and we went to a place I have visited countless times before: Sonoma State’s Fairfield Osborn Preserve. I offered this optional weekend trip to my Introduction to Biology students for extra credit, and it was a fantastic day!

California Tiger Salamander Research

Earlier this month, SSU graduate student Jesse Schmieg offered my Vertebrate Biology students an amazing experience: my students were hosted at Jesse’s field site, where they are researching the interactions between larval tiger salamanders and predaceous diving beetles in seasonal pools. Our main task of the day: to help Jesse set up this season’s experiment. This involved “bisecting” each vernal pools into two halves, using mesh fencing. Throughout the season, Jesse and their team of research assistants will remove predaceous beetle larvae from one half of each pool, while leaving the beetle population undisturbed in the other half. Then, they will perform monitoring to see if there is any difference in the salamander populations related to the removal of these insects.
