Last week, we wrapped up the last of the fieldwork in Minnesota, although four Liatris plants are taking their sweet time and weren’t ready to harvest on Friday. The remaining members of Team Echinacea packed their bags and headed to the Chicago Botanic Garden, with the exception of Jared, who is staying to monitor the stubborn Liatris. Previously, I had never been to the Garden before, so it’s been a fun place to explore. I’ve also enjoyed the elaborate Halloween decorations in the neighborhood.

This week at the Botanic Garden, we welcomed back Allen, our first volunteer since the beginning of the pandemic. It will be terrific to have some experienced volunteers to process the backlog of echinacea heads from the past several years.
At the lab, we’re also preparing for the seed addition experiment. Today, Wyatt trained us in on the seed blower, a contraption that separates light achenes from heavy ones. The heavy (rich) achenes should contain seeds, and we will next randomize the rich achenes for planting this fall. We need 12,800 seeds for the experiment, and after several trials with the seed blower, we estimate that we should have enough.
This summer Shea and John continued our yellow pan trap project to sample the pollinator community found along roads in our study area in Minnesota. Today volunteer Mike Humphrey pinned the last bee from this summer’s collection!
Mike with the collection; next he’ll be consolidating these with Shea’s pinning from this summer to be sent off for ID at the University of Minnesota!
Mike received a surprise on his last day of the year; volunteer Char found a desiccated bee in one of the Echinacea heads she was cleaning! Mike reports it’s different from anything else we have in the collection this year, so a seriously cool find.
A majority of the bees in our 2019 collection are unremarkable Lasioglossums that we call “small black bees,” but we also get remarkably shiny blue and green bees in our traps!
Thanks for all your hard work Mike, and we’ll see you next year!
Last Thursday, we had our annual Team Echinacea potluck to honor the work of lab volunteers over the past year. Stuart discussed why what we do is so important and how the work of volunteers helps us to answer important scientific questions. Some great recent milestones accomplished by volunteers include:
Allen, Sam, and Anne reaching 500,000 achenes counted
All 2017 heads have been cleaned, rechecked, and scanned
670,000 achenes were counted and 113,000 achenes were classified in 2019 (so far)
In addition to a general overview of the Echinacea Project’s goals, members of the lab who have individual projects talked about what they are working on. These projects are: Erin’s remnant flowering intervals, Drake’s prairie parasites, Lea’s floral neighborhood, Elif’s congener ploidy project, and Riley’s prairie fragment crosses. It was really great to talk about research and hear about a number of projects.
Most importantly, though, I want to thank all people who volunteer their time to the lab. Without you, the cutting-edge science we do is impossible. Truly, you are making huge contributions to science and our understanding of plant reproductive fitness in anthropogenically fragmented landscapes. Your work is so appreciated, and we are so lucky to have you all around!
Oh, by the way, the food was absolutely wonderful. 11/10.

Recently, Team Echinacea welcomed a new member, Elif Taskiran. Elif has a PhD in economics, but has recently expressed interest in biological sciences. The Echinacea Project is happy to have her on board! Elif volunteers her time on Fridays, where she engages in data entry and cleans heads. Elif also attends weekly lab meetings, where she engages in paper discussion and gives feedback on various works of the team (like presentations and proposals).
Elif is also very interested in using Chicago Botanic Garden’s flow cytometer to understand ploidy differences between Echinacea angustifolia, E. pallida, E. purpurea, and Echinacea hybrids. We hope this project will be fruitful! Thank you, Elif, for all of your work so far with the Echinacea Project. We look forward to your work in the future!
Since Stuart and Team Echinacea have started summer field work in Minnesota, you might guess the lab at CBG slowed down- but you would be wrong! Last week we finished cleaning another bag of Echinacea heads, and this week we’ve gone through over half of the next bag! People counting achenes and classifying x-rays have also been super productive, and some of the newer volunteers finally got their official CBG badges. So even though there’s a lot going on in Minnesota, we’re still busy back in Chicago. Stay tuned for more lab updates throughout the summer.

For those of you who read all of my flog posts (I know there’s a solid number of you out there!) you’ve probably figured out by now that I love posting about numbers. So what’s today’s number?
Why, it’s 1948 of course!
Now this is the point that you might furtively look at wikipedia and say “I don’t understand what 1948 has to do with Echinacea. Everyone already knows that 1948 was a leap year starting on Thursday of the Gregorian calendar, the 1948th year of the Common Era (CE) and Anno Domini (AD) designations, the 948th year of the 2nd millennium, the 48th year of the 20th century, and the 9th year of the 1940s decade.” To which I would say that we are dealing with the number 1948, not the year.
No, 1948 is the number of seed packets of echinacea we x-rayed at the garden this week: and it’s only Wednesday! Through the combined efforts of many volunteers we are making some headway into the daunting task of figuring out which achenes have seeds in them and which do not. Look for updates soon about these number for our pollen limitation heads!

p.s., here’s a small sampler of what the xrays look like

Today we celebrated Anne’s accomplishment of counting over 500,000 achenes with a prairie remnant made out of cupcakes. Anne has been a member of Team Echinacea for over 10 years and she has really put in the hours! We can’t thank her enough; it’s great having her in every Friday.
Notice the cupcake “soil” under the diverse cupcake prairie remnant – complete with Echinacea, Helianthus, bottle gentian, and grass!
Prairie cupcake remnant. Are these bare ground cupcakes good for solitary bees??
Last week, Allen and his wife Doris won an amazing award at the Volunteer Awards Reception! Congratulations Allen and Doris!
Allen and Doris were presented with the 2018 Kris S. Jarantoski Excellence In Horticulture Volunteer Service Award, an award that recognizes volunteers for “their dedication to nature, enthusiasm for education, and exemplary volunteer service in support of horticulture and plant collections at the Chicago Botanic Garden.”
We have been so happy to have Allen on our team. He is a long-term volunteer at the garden and has worked on a variety of different projects over the years. He comes in on Tuesday afternoons to work with Team Echinacea and is one of our critical achene counters! Thanks for all of your hard work, Allen- this award is well-deserved!

Susie, a member of Team Echinacea since 2011, was also recognized for volunteering over 600 hours this past year! That is quite an achievement. Susie would come in all day Tuesdays and Thursdays, starting out with randomizing or cleaning in the mornings and then working in the herbarium in the afternoon. Susie did so much great work for the Echinacea Project, always had a smile, and was always keen to learn about what the lab managers and grad students were working on.
Anne and Leslie are hard at work rechecking heads that have been cleaned from 2016. This is an important job in our ACE protocol as it makes sure that no achenes are left behind before they get counted and randomized!
