A new study by former UC/JEPS graduate student Isaac Lichter-Marck and his major professor, Jepson Curator Bruce Baldwin, explores the role of edaphic specialization and life history switches in the evolution of rock daisies, and uses this system to examine potential limits on the responses of desert angiosperms to global climate change. The paper is available here, and the UC news release is here.

We are sad to announce that Rudi Schmid passed away January 4th, 2022. He was an active faculty member at UC Berkeley for over 30 years, 1972-2003, as well as a curator in the University and Jepson Herbaria. He had research interests in plant anatomy and was an advocate for botanical documentation and a champion of floristic efforts, including the Jepson Flora Project. He has established an endowment fund in the Herbaria to support research on and curation of conifers; if you would like to contribute to this fund, please contact Staci Markos (smarkos@berkeley.edu).

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 baseline for monitoring extinction in the Anthropocene. Jepson Curator Bruce Baldwin and UC/JEPS Director Brent Mishler contributed to an analysis documenting which plants in North America have already gone extinct. Available data suggest 65 vascular plant taxa from this region have become extinct since European settlement, 19 from California alone (thumbnail shows one of them, Calochortus monanthus, the only specimen ever collected, in 1876). Read the open source paper here, and New York Times article here.

Woody vines do the twist! The research of Joyce Chery, done as part of her PhD dissertation in the labs of UC/JEPS curators Chelsea Specht and Carl Rothfels, was featured in the New York Times. She showed how the unique evolution and development of wood in lianas allows them to be both strong and flexible, to twist through the forest canopy without breaking. Dr. Chery is currently an assistant professor at Cornell University. See her webpage here.

Mosses can hide under rocks in the desert! Jenna Ekwealor, a graduate student in the Mishler Lab, along with alumna Kirsten Fisher, made this fascinating and unique discovery while studying how mosses are able to live and reproduce in dry deserts.
