It has been a while, but I’ve been busy…

photoIMG_8879Hey, all — I wanted to share a short post with you, some links that detail my activities in the field over the last two weeks in Idaho and Montana. I’ve been on the hunt for Claytonia, Silene, Boechera and Androsace in alpine areas across these two states, including my new favorite mountain range, the Sawtooth Range (pictures above). At the end of this trip in Idaho and Montana I got my first ever glimpse of the alpine Claytonia megarhiza (pictures below) — I’m beginning to think I should have selected that species for a more thorough investigation… I suppose there is life after dissertation, so maybe this can be my next problem child. đŸ˜‰

IMG_8952IMG_8954My collaborator, Ingrid Jordon-Thaden, and I have been to some pretty spectacular places (see links below), but it is only going to get better (I think) when we head north to the Yukon (Canada) following the 2014 Botany Conference. I look forward to keeping you all in the loop!

THANKS (Experimental Success!)… and a report on my Northern California and Southern Oregon trip to sympatric Claytonia sites

IMG_7744Above, two members of the genus Claytonia from different Sections — C. “serpenticola” (an undescribed species in Section Claytonia) on the left, and C. rubra (Section Limnia) on the right. The two occur in close sympatry in the Lassic Mountain Wilderness, practically high-fiving their cauline leaves. This was a highly productive trip to the north, but before I get to that…

 

I want to say THANKS to all who supported my recent fundraising endeavor with Dr. Ingrid Jordon-Thaden on Experiment.com — we are going to be able to do some much needed fieldwork and conduct fundamental biodiversity research with the money you have all helped us to raise! Thanks so very much, and stay tuned for updates (Lab Notes and Blog Posts) on this ‘open access’ alpine research.

 

OK, back to talking about my recent trip to Oregon and California — I was on the hunt to find locations where multiple Claytonia occur in close sympatry, particularly areas where species may be hybridizing. I am interested in knowing just how well species can maintain their identities in these situations…

IMG_6819I started the trip by meeting up with Larry Crawford for some botanizing in the Sierra Nevada — we found Claytonia sessilifolia (Torrey) Henshaw(pictured above) flowering profusely near Carson Pass in an area that Larry had previously scouted. This plant was featured in the recent Spring Beauty Pageant hosted on my website — it isn’t too late for you to cast a vote for your favorite(s)! In this population it seems like there is only one species present (C. sessilifolia), but this taxon occurs in an interesting habitat (pictured below, with Diana Jolles and Larry Crawford). It also occurs next to some other fantastic spring ephemerals, such as Dicentra uniflora (pictured below) — the hike was well worth it!

Following some rest and recovery at Larry’s house (thanks, Larry and Suzanne!), my colleagues and I continued north to Lassen Volcanic National Park, catching a wonderful view of Mt. Lassen (pictured below) — this was my first time taking in such a beautiful sight. I also have never (knowingly) been this close to a stratovolcano. I can’t say that I was nervous that the mountain might erupt, but it actually hasn’t been long since something like that happened (click here to read more about the geologically recent eruption of Lassen Peak). Unfortunately we didn’t find any Claytonia in this area, but we might have also been a tad on the early side for the area we looked — several feet of snow in some drifts. It has been a bit of a whacky weather year…

IMG_6885Having been thwarted by a lack of Claytonia at Lassen Volcanic National Park and lower elevation sites in Lassen National Forest, I decided to book it northward to Crater Lake National Park in an attempt to catch up with a rapidly fading spring. Many of the areas in California where Claytonia have previously been reported as abundant are looking quite parched — the Spring Beauties are apparently less than pleased about it. At Crater Lake, though, we found C. sessilifolia plants blooming where else but in the parking lot (pictured below)!Snagging a few quick pictures of the cinder cone “Wizard Island” (pictured below) in the middle of Crater Lake was just a bonus of doing fieldwork in the area. đŸ˜‰IMG_6959

IMG_7012

We found some more plants a few miles north of Crater Lake NP on the Rogue River-Siskiyou National Forest, and I also happened to snap a quick picture of the BEAUTIFUL Mt. Thielsen (pictured below) on my way out of Crater Lake National Park — this is another place I’ve got my eye on visiting. I’ve heard the Claytonia on Mt. Thielsen are quite interesting… IMG_7019

Next was Abbott Butte (west of Crater Lake National Park) — I ABSOLUTELY had to visit that area this year, as it is the type locality for Claytonia obovata Rydberg. Ray Davis chose to sink this taxon into synonymy in the 1960’s — it has been treated as C. lanceolata since that time. Ray mentioned in his 1966 North American Perennial Species of Claytonia that he collected plants answering the original descriptions of C. obovata, C. multicaulis, and C. chrysantha, as well as C. lanceolata at Abbott Butte. Although he didn’t recognize C. obovata, tubers he collected of that taxon from around the type locality that he grew in a ‘common garden’ retained their rounded leaf shape. What did I find at Abbott Butte? Claytonia lanceolata (pictured below, lacking bifid petals), but not any C. obovata — did it not come up this year? I’ve certainly observed this happening before with C. “peirsonii” in southern California… at least Julian (pictured below) found some delicous black morels (Morchella elata-M. angusticeps-M. conica complex). = YUMMY.IMG_7177

What do you do when you can’t find a species at its type locality? You write a paper about it  — look for Stoughton et al. (in prep.) coming to a Madroño near you. Fortunately, I have seen C. obovata previously with Heath Bartosh at Hull Mountain — this area is also mentioned in the protologue for C. obovata Rydberg. I did find C. obovata with Diana Jolles and Julian Roberts later during our trip near Cory Peak and Mount Eddy on the Shasta-Trinity National Forest in the Klamath Region of California, but I want to tell you first about the next stop on our road trip at the Siskiyou Mountains of southern Oregon — Observation Peak (pictured below) is an area where C. “serpenticola” (pictured below, and at the beginning of this post) is known to occur.IMG_7263

IMG_7259

After seeing C. “serpenticola” (pictured above) more or less ‘alone’ in the Siskiyou Mountains of southern Oregon on serpentinite and peridotite, we next saw C. obovata (pictured below) similarly secluded in the Scott Mountains of California near Cory Peak — I now had my search images for a hike that was a major part of the trip. The two species occur in sympatry at Deadfall Lakes just below Mount Eddy, which is where we were headed next. I REALLY want to measure levels of hybridization in this population on Mount Eddy — obvious intermediates exist in the area in seemingly marginal habitats.

IMG_7414

What do hybrids between C. obovata and C. “serpenticola” look like? They probably look something like the pictures below — the two species occur in very close proximity in this area…IMG_7574

IMG_7685

SUCH A COOL SPOT — I will revisit this area next year when there is hopefully a bit better snow pack (which generally = many happy Claytonia). Who is coming with me?! I’m climbing up to the top again for sure. Claytonia “serpenticola” (pictured below) grows very near to the summit, and the view of Mount Shasta (pictured below) from atop Mount Eddy is SPECTACULAR.IMG_7698

IMG_7721

After poking around Mount Eddy with Dana York and Julie Nelson, and a much needed night of rest (Thanks, Dana and Eva!), Diana and Julian headed with me south to the Lassic Mountain Wilderness (Six Rivers National Forest) and Anthony Peak (Mendocino National Forest) to see C. “serpenticola” (pictured below) and C. obovata (pictured below) at additional areas where they occur in allopatry — plants were pretty crispy in northern California, but they were still identifiable!

I am VERY excited to see how things shake out in the molecular phylogeny I am developing for this group… Stay Tuned!!!

Will the REAL Claytonia lanceolata please stand up…

Hey all!

I wanted to take this opportunity to give you a brief overview of my dissertation research, hopefully explaining a bit better how my own research relates to the AWESOME project I’m flying for a limited time only on experiment.com in collaboration with Dr. Ingrid Jordon-Thaden — I know you’re interested in supporting a good cause, so check it out! See the project here.

Many of you may think that you have seen Claytonia lanceolata some time during one of your forays out into the field, but have you REALLY seen it, or just something that looks like it?! Where were you when you saw it? If your answer isn’t Sweetwater, Idaho, than I’ve got some news that could make you want to reconsider what you think you saw — it is possible that you’ve been duped by a lance-leaved imposter!!! Don’t worry, you’re not the only one…

pursh1814_sketch.tiffAbove is an illustration of Claytonia lanceolata from the original description published in the Flora Americae Septentrionalis (Pursh 1814). The illustration is putatively drawn from the type material collected by M. Lewis, although one cannot be entirely sure given how poorly Claytonia seem to make the transition from live plants in the ground to becoming flattened museum specimens — their succulence does not do them any favors in terms of preserving diagnostic morphological characteristics.

Did your plants look like the one in the above illustration from the original description? What about the plants below photographed in the Klamath Region of northern California, last year, growing very near to North Trinity Mountain — did your plants look like these? As far as I can tell, this is the REAL Claytonia lanceolata,or at least something VERY closely related, the best proxy I’ve got (for now) for C. lanceolata sensu stricto.

2013-05-30 11.37.042013-05-30 13.44.13I mention these might be only very near C. lanceolata sensu stricto because these plants have entire petals — C. lanceolata is described as having bifid petals, probably more similar to something like what you see on the flowers of C. sibirica. The basal leaves are also lacking in the plants pictured above from northern California (only observed to be associated with non-flowering individuals in the population), but the sessile, triple-ribbed, ovate cauline leaf pair and the lax, elongate, solitary inflorescence is a dead ringer for C. lanceolata Pursh. The plot thickens when you step off of the granite and onto ultramafic substrates…

2013-05-28 11.53.36 2013-05-28 11.12.53Wait a second — is that a second raceme I see? Lance-linear cauline leaves with a single vein? And are those leaves ALTERNATE?! Surely this is not the same as C. lanceolata sensu stricto — this is one of many lance-leaved imposters masquerading as C. lanceolata Pursh. For better or for worse, the Operational Taxonomic Unit (OTU) above is treated as C. lanceolata in the recent monograph for Claytonia (Miller and Chambers 2006) as well as in current treatments in the Jepson Manual and the Flora of North America. The following plants photographed in populations from throughout California also are ALL treated as C. lanceolata under the current circumscription by Miller and Chambers (2006):

IMG_2684IMG_9512IMG_5528IMG_5450IMG_49592014-02-15 13.41.46Whoa — I feel like this kind of variation might not ALL be related to ‘plastic’ responses to a heterogeneous environment… and preliminary molecular data seems to agree thus far.

This is where the Experiment Project is a TREMENDOUS help — It’d be great to get more samples from outside of California… expanding onto more substrates from across the distribution of C. lanceolata sensu lato, which ranges from Canada to Mexico. Idaho, Montana, and Yukon Territory are on this bill…

The REAL kicker? Check out the last line in Pursh’s 1814 description of C. lanceolata below: pursh1814.tiff“In the collection of A. B. Lambert, Esq. I found a specimen collected by Pallas in the eastern parts of Siberia, perfectly agreeing with the present species.”

Did you see my post about going to Siberia? I’m working on a grant for that right now… I’m really eager to see more plants in the field — as I mentioned previously, these plants don’t preserve all that well! đŸ˜¦

Can I borrow $20? I’ll pay you back with publications…

Hey all — two quick ‘news’ items:

(1) I passed my qualifying exams… wow! Next step, actually writing my proposed dissertation. I am thinking something along the lines of this FUN title:

Circumnavigating the Claytonia lanceolata Species Complex: Systematic Studies of Claytonia Section Claytonia (Montiaceae).

(2) If you haven’t heard already — I am involved with another crowd-sourced fundraising effort in collaboration with a colleague at Bucknell University, Dr. Ingrid Jordon-Thaden. This is the type of fundraiser where EVERY contribution counts! Even if you were to pledge $1, you would help to demonstrate just how much interest there is in research projects like this one.
