Last week, Rothfels Lab PhD candidate Carrie Tribble taught a few of us aspiring bioinformaticians/botanists/ecologists how to think (and do some things) in R. She is an excellent teacher, as she was able to meet each of us at our different levels of experience and expertise (a skill that was lacking in my past “for beginners” R workshops).
Carrie walked us through some basic R commands in RStudio while simultaneously helping us to navigate through our directories (and our own minds, as needed). She demonstrated how critical it is to understand the structure of our data, how to call up summaries and/or subsets of our data, and a bit on variables and object classes. She empowered us in how (and when) to look for help for specific R functions. Then we ran out of time.
It is with great sadness that I write to inform you of the passing of Dr. Vicki Funk, who was a friend and collaborator to many of us at UC and a pioneer in the field of plant systematics.
Vicki worked as a curator at the Smithsonian institution in Washington D.C. for 38 years and hosted hundreds of students, post-docs, visitors, and researchers. Her battle with a cancer of unknown primary lasted less than a year and she passed away in her sleep last night.
Here are a few facts about Vicki:
She pioneered phylogenetic systematic thinking in botany. Her Ph.D. thesis on the arborescent sunflower genus Montanoa was the first botany study to explicitly use a cladistic approach.
As a grad student, she drove by herself in a beat-up old pickup truck to Panama and back twice collecting sunflowers.
Her embrace of cladistic thinking drew heat from stalwart pheneticists, but she stood her ground and was vindicated by history, becoming one of the most prominent researchers plant systematists in the US.
As an early career scientist, she switched to driving a VW beetle with a vanity license plate that read CLADIST.
She dedicated her career to the study of Compositae, the sunflowers and daisies and was at the peak of her accomplishments when she received her diagnosis.
The results of decades of hard work by Vicki and colleagues to resolve relationships among Compositae, one of the most diverse plant families, were published in PNAS earlier this year.
She was an important advocate for the importance of natural history collections to biodiversity research and conservation.
She was a hard working, extremely generous, and light hearted person who was admired around the world.
She could make a room full of people roll over laughing.
In one of her last text messages to me, she asked if I would bring her some Montanoa from the field. She may have wanted to revisit study of the genus that was the subject of her PH.D. with new molecular methods. Or she might have just wanted to see and smell the flowers one more time. Knowing Vicki, it was probably both.
The culmination of the now nine-year-long One Thousand Plant Transcriptomes (1KP) project was published today in Nature, and apparently will be on the cover of the print edition next week. The 1KP project has revolutionized the availability of molecular data for ferns (among many other things), and facilitated dozens if not hundreds of other research projects so far. It’s been a pleasure and an honor to have been able to participate in this project, and it’s very exciting to have the capstone completed and available.

The illustrious Michael Sundue came to visit! Much research was done (TED, TED, and TED), and we co-enabled our co-dependency with fieldwork for a day in Marin County (thanks John for the itinerary!). We managed a total of 17 fern species, one lycophyte, and 12 mussels. Not bad! Oh, and Sol Food. Fantastic.
Sundue getting cozy with Aspidotis carlotta-halliae, a California endemic allopolyploid. We saw A.densa, too, for 50% of the global Aspidotis diversity. They were all pretty crispy, like this.What is this? Anyone, anyone? Sweet huge thalloid liverwort.Equisetum arvense, which I don’t see very often around here (it’s almost always E.telmateia). And in a “native-looking” setting, rather than the weedy habitat you tend to see it in in the east.Presumably Dryopteris arguta, but we had Dryopteris expansa on the brain by this point (it was the more common Dryopteris at this site), and were trying to convince ourselves that this was a hybrid.Adiantum aleuticum — the day’s final fern.No caption needed.
Addendum–fieldwork isn’t without its risks…. Damn you Toxicodendron!!!
The Google doodle today celebrates the famous Berkeley botanist Ynes Mexía, who collected ~150,000 specimens and did much of her fieldwork alone, which is all the more impressive given that she didn’t start her botanical careers until she was in her 50s!
See more about her here, and here, and if that piques your interest, we are lucky enough to have her archives here at UC/JEPS.
Dr. Dori, Curator. Of paleobotany, at the Perot Museum!
This has been a summer of good news for senior Rlabites, and I’ve been belated in sharing. First, congratulations to Dori for landing the position of Paleobotanist at the Perot Museum! Not only is this an amazing position in a super cool museum, but it’s back in Dori’s native Texas, close to family. She couldn’t be happier, and we couldn’t be prouder!

And in case you weren’t sure exactly how Dori feels about this position, here she is contemplating the job offer. Or sneezing.
Holy moly, Operation Desert Fern* III was an amazing, hot, exhausting, and successful trip to the mountains of southern Arizona at the end of July. While some would consider us crazy botanists for attempting such a trip in the pre-monsoon Desert Southwest, I would consider us crazy and happy botanists.
Santa Catalina Mountains.Gold morph of Notholaena standleyi, first fern of the trip. Look at those marginal sporangia!Notholaena standleyi.
Our first stop (after a rather sweaty and sleepless first night camping west of the Santa Catalinas) was Finger Rock Canyon in the Santa Catalinas, just north of Tucson. This was our hottest field day, but in some ways the most exciting, as we met so many new ferns and were thrilled to discover that things were not as shriveled as expected! Apparently the canyon had received some early monsoon rains, so at least some of the plants were looking lively. That first day we saw Notholaena standleyi, Astrolepis sinuata,A. windhamii, Pellaea truncata, Myriopteris wrightii, M. lindheimeri, M. yavapensis, Selaginella arizonica, S. rupincola, and finally, at about 1136m in the afternoon, Pentagramma maxonii—these collections turned out to contain both diploid and triploid individuals!Yahoo!

Oh, and I spy Finger Rock, top R horizon!The spot where Keir nearly fell to his spiky doom. And where we saw a rattlesnake enjoying a meal in the shade. And some lovely Myriopteris wrightii!
Sraavya, superstar, spent her summer at an internship at Stanford working on cell signalling in the immune response to viral infection. Of course she did!! The Rothfels lab is very proud!
