Fieldwork in Monahans Sandhills State Park, one of the study sites for our research focused on how local adaptation and hybridization shape genetic variation in shinnery oak—a foundational species that stabilizes sand dunes in the south-central US.

Curro! For real, that place is something else. We camped at a very remote place and it was incredible. Being way out in the middle of nowhere, the stars were just mind-blowing.

Here are some photos from our fieldwork at Big Bend Ranch State Park! We collected leaf samples from Quercus hinckleyi to investigate epigenetic variation within populations. This research is supported by the International Oak Society.

Fieldwork in western OK! Today we scouted for shinnery oak populations in Quartz Mountains and surroundings. What a cool place Quartz Mountains State Park! Finally, we found our study population near Blair. Ryan has another piece of information for his assessment of the species’ genomic variation!

The last display of our department is about the OSU Herbarium. The OSU Herbarium contains approximately 157,000 vascular plant specimens, about two-thirds of which were collected in Oklahoma and surrounding states. The oldest specimen dates from 1843, and the collection contains 300 type specimens.
