Searching for the next Jepson Curator.

With the retirement of Bruce Baldwin, following a distinguished career, we are looking for the next Curator of the Jepson Herbarium, the epicenter of research and education on the vascular plants of California. The new Curator will lead the Jepson Flora Project and curation of the Jepson Herbarium, pursue their own research interests, and participate in our outreach programs. More details are here, and here is the application page.

Have you been wanting to visit the University & Jepson Herbaria (UC/JEPS)? Well, you’re in luck! We are officially announcing the beginning of regular public herbaria tours. Four times a year, there will be the opportunity to come learn all about UC/JEPS and herbaria. We’ll discuss how we started, how herbarium specimens are collected and how they end up here, our curation practices, ongoing projects, and so much more! Beautiful specimens will be on display, and curators from the different collections will be available for questions. There are two tours coming soon:

Thursday, April 25th at 10:30AM and Thursday, July 11th at 10:30AM

Spots are limited! Sign up here today if you’re interested in a tour:

Tour groups will meet at the front of the herbaria, located at: 1001 Valley Life Sciences Building Berkeley, CA 94720-2465

We look forward to seeing you!

A new book entitled "What, if Anything, are Species?" by UC/JEPS Director Brent Mishler explores this controversial topic in detail, based on 40 years of investigation. He concludes that species are nothing special; entities currently given that rank are simply clades like taxa at all other levels on the tree of life. He goes into the advantages of fully rankless classification, and of a multi-level approach to ecology and evolution. The book is open access; it is freely accessible here.

A virtual Jepson Workshop was held Saturday, January 30, 2021: "Wonders of a dryland moss: Syntrichia from genomes to ecosystems," hosted in partnership with the collaborative research project "Desiccation and Diversity in Dryland Mosses," with funding provided by the US National Science Foundation. In order to make the workshop available more broadly, recordings of all eight 15-minute presentations have been uploaded to YouTube. See introductory page and links to this self-paced workshop here.
