Ecology | Evolution | Conservation
We study the many factors that determine species distributions. Specifically, we are interested in plant adaptation and the processes that lead to both local adaptation and speciation. We use a great variety of methods, from genomics to distribution modeling to field and lab experiments. We also conduct research in a broad set of ecosystems, from deserts to vernal pools to mountains, and at a wide variety of scales, from genes to plant endophytes (e.g., bacteria and fungi) to plant communities. Our current research projects occur in California, Mexico, and Australia and are focused on the effects of environmental change on species range limits, the determinants of specialization (niche breadth), and the role of gene flow on adaptation. We are also focused on understanding vulnerabilities and adaptive responses of plants in the face of global change and we actively engage in interdisciplinary collaborations in order to develop solutions for conserving biodiversity.
Congratulations to former lab member, Dr. Molly Stephens, on her new role as director of the Sierra Nevada Research Institute at UC Merced!
Congratulations to Lillie Pennington et al. on a new paper in Evolution that investigates patterns of genetic adaptive potential of populations across species’ geographical ranges.
Congratulations to Jackie Shay on completing her PhD! Jackie now transitions to be the full-time associate director of the UC Merced Center for Engaged Teaching & Learning.
Congratulations to Jorge Montiel on successfully defending his PhD thesis!
A new paper led by Ezra Kottler exploring the question of how gene flow effects the adaptive potential populations on the edges species ranges has been published in Trends in Ecology and Evolution.
What’s “eDNA?” A paper led by Rachel Meyer describing the California environmental DNA (CALeDNA) program has been published in the journal California Agriculture as part of a special issue on community (aka citizen) science.
RadioBio, our campus science outreach podcast, has received the UC President’s Award for Outstanding Student Leadership. Congratulations to the grad. students who have developed and maintained this podcast through the years, including students in our lab. RadioBio has also been included in NSF’s online multimedia platform, ‘Science 360,’ a big honor.
COVID-19 has changed the world and we wish everyone good health and peace as we all adapt. So many people are helping others in this challenging time and we are thankful. Here is a brief example of how Jackie Shay has been helping others transition to remote teaching as our university has had to shut down most operations. Thanks, Jackie, and thanks to all who are helping out in so many ways.
Congratulations to Brandon Hendrickson on advancing to candidacy in his PhD program!

Molly Stephens is the new Associate Director of the UC Merced National Reserve System. In this new position for the campus, Dr. Stephens will be lending her vision and expertise to help further plan, develop, and manage UCM’s reserves, including the Vernal Pools and Grassland Reserve, the Yosemite and Sequoia Field Stations, and SCICON. We are very fortunate and excited have Molly back at UCM!
