Recap of past year & summer 2017 field season

It’s time to prepare annual reports to NSF for our two long-term awards through CBG & through UMN. The period covers 1 April 2017 through 31 March 2018. So, here’s a brief recap of activities from the past 12 months including the summer 2017 field season.

Last spring we were busy in the lab. Led by interns Amy & Scott, volunteer citizen scientists at the Chicago Botanic Garden started cleaning heads harvested in summer 2016 to count all of the achenes to generate a detailed and precise dataset of annual plant reproductive fitness. We were way behind because of the huge flowering year in 2015. We worked all fall & winter and we are in good shape now. Led by Tracie, we are cleaning 1148 heads harvested from plots in 2017, which we will finish over this summer.

Several undergraduate students have worked on projects in the lab, including Nicolette, Ashley, Marisol, Nina, Trevor, and now Danielle. They are all gaining experience, learning a lot, and contributing to science! Graduate students are hard at work too. Lea has analyzed all of her summer phenology data on Solidago & Liatris. Kristen is working on the bee collection from last summer with Mike. They are both making research plans for summer 2018.

Last December, we submitted a paper to Oikos titled “Pollinator-Mediated Mechanisms for Increased Reproductive Success in Early Flowering Plants.” We haven’t heard anything for 101 days & wonder if it has disappeared into a black hole.

Our team accomplished a lot in summer 2017! The 2017 summer team, shown below, included three undergraduate students (Ashley, Will & Wes), a high-school student (Anna), two graduate students (Lea & Kristen), and two recent college grads (Tracie & Alex)–not to mention the usual suspects, Gretel, Ruth & Stuart. We summarized progress on many summer projects last fall & made flog posts. Here are links to the updates organized into six groups.

First, we measured survival, growth, and flowering effort of our model plant, Echinacea angustifolia, in several experimental plots. The earliest was established in 1996 and the most recent in 2015:

Second, we measure other traits in these plots, including flowering phenology. We also have some treatments, such as pollen addition and aphid addition, which we apply every year. Will has super-cool estimates of the heritability of flowering timing. He is polishing the manuscript and will submit it soon. Amy W. has a manuscript in review that quantifies reproductive synchrony in the 1996 cohort of plants. She estimated how much within-year synchrony (daily phenology) and among-year synchrony (annual flowering) contribute to long-term mating opportunities.

Third, we make observations of Echinacea plants in natural prairie remnants in our study area, including flowering phenology, survival, reproduction, and incidence of disease. Scott is investigating effects of fire on population growth rates in our remnants using a life-table response experiment approach. While she is on sabbatical, Amy D. is analyzing the seedling establishment dataset.

Fourth, we study plant species other than Echinacea angustifolia and we are very interested in pollinators, including native solitary bees.

Fifth, two REU participants worked on our Team last summer. Here are updates of their projects.

Sixth, we are worried about non-native Echinacea plants that are used in restorations and how they impact populations of the native Echinacea angustifolia. We have several ongoing experiments that investigate a population of Echinacea pallida introduced within our study area.

Bees in summer

Winter blues got you down? Watch some bees pollinating Echinacea plants!

Echinacea Project Videos on YouTube

Ahh, summer! We have lots of footage from experiments where we observed native solitary bees visiting Echinacea heads. Note: these bees aren’t visiting to pollinate. They are collecting pollen to eat or to feed to their babies.

Enjoy!

congratulations, Lea!

Congratulations to Lea Richardson. She was just appointed a Dr. John N. Nicholson Fellow at Northwestern University for the 2018-2019 academic year!

What we did this summer

Over the next several weeks we are going to post updates on all the projects we worked on during summer 2017. Whew we did a lot–it might take a couple of months!

Team Echinacea summer 2017

Put a bookmark on our update page to stay caught up. We’ll post all updates on that page.

Two new projects to look out for are Richardson’s “Liatris and Solidago phenology” and “Pollinators on roadsides.” Also, we’ll recap Barto’s & Braker’s REU projects. Stay tuned!

We didn’t work on the project Fire & flowering at Staffanson Prairie Preserve
or on Mating compatibility in remnants this summer. We didn’t do the first one because no burns were conducted at the preserve before this growing season. We contemplated assessing compatibility for another year, but there seemed to be more things that we wanted to do than there were people and time to do them.

Scott’s last day

Today was Scott Nordstrom’s last day working at the Chicago Botanic Garden with the Echinacea Project. Scott completed a 13-month internship, during which he worked in the field in Minnesota, assessed lifetime fitness of Stipa plants in our common garden experiment, improved a workflow for taking x-ray images of Echinacea fruits, contributed to analysis and management of numerous long-term experiments, supervised citizen scientists in the lab, and made many other valuable contributions. It was great to have him on the team. This fall, Scott starts a PhD program at the University of Colorado in Boulder. Best wishes, Scott!

Amy’s last day

Today was Amy Waananen’s last day working at the Chicago Botanic Garden with the Echinacea Project. The last few days were a flurry of activity with our potluck, preparing for prescribed burning in Minnesota, and getting ready for the summer field season. On top of that, Amy submitted a manuscript about reproductive synchrony to The American Naturalist. It’s sad to see Amy leave but we’re happy that she will be nearby. She is working out on the prairie in western Minnesota the summer with her new lab group. It is great she is starting a PhD program at the University of Minnesota this fall. Good luck, Amy!

Team Potluck

We had a great time at our annual lab potluck on Tuesday. We celebrated all the people in the lab, including all of the undergraduate interns. Scott told us about the smoke experiment. Then Amy explained the pollinator study from 2016. Lea talked about her projects on flowering phenology. We reviewed some of our many accomplishments in the lab, including: 1) cleaning and randomizing all 1233 heads from exPt2 in 2015, 2) counting 478,069 achenes from 3078 heads, 3) scanning 1710 images, 4) assembling 198 xray sheets. This year Lois, our reigning “achene queen,” counted her 800,000th achene and Sam counted his 250,000th! This summer we have ambitious plans for the field and lab. It was a lot of fun and the food was great–an incredibly diverse spread of tasty dishes.

We took a group photo:

First row (L to R): Lois, Art, Leslie, Amy, Laura; Second row: Susie, Char, Gretel, Anne, Stuart, Allen, Mike, Ivy, Lea, Scott, Shelley. Not pictured: Aldo, Susan, Michele, Marty, Naomi, Sam, Kathryn, Lou, Suzanne, Nicolette, Sarah.

Thanks for a great year!

Ten simple rules for a short talk

Christopher Lortie presents ten simple rules for successful short and swift presentations in this PLOS Computational Biology paper.

10 simple rules:
1. Plan a clear story
2. Provide only one major point per slide
3. Limit use of text
4. Use simple visuals
5. Develop a consistent theme
6. Repeat critical messages twice using different visuals
7. Use the principle of parsimony in explanations
8. Allocate more than one slide to effectively end the narrative
9. Use the final slide for contact information and links to additional resources
10. Use timed practice

Lois counted her 800,000th achene today

Lois Jackim, citizen scientist working on Team Echinacea since 2009, counted her 800,000th Echinacea achene this morning around 9:30 AM. Scientists from the Chicago Botanic Garden and Northwestern University were present as Lois was presented with a giant check thanking her for her dedication to plant science and conservation. Lois wore her “Achene Queen” crown, which she earned in 2015 after surpassing the half-million mark. Lois was not aware she was so close to the 800,000 milestone.

Counting fruits, also known as achenes in Echinacea, is a critical activity for scientists measuring reproductive fitness of plants. The Echinacea Project conducts experiments to assess environmental and genetic factors that influence plant fitness. Echinacea Project research contributes to basic ecological and evolutionary science in addition to informing conservation of perennial plants and prairies.

Other citizen scientists present this morning were cleaning and preparing seedheads and making digital images for counting. Each year the Echinacea project harvests heads from experimental plots and volunteer citizen scientists at the Chicago Botanic Garden count all achenes from each head. Citizen scientists also x-ray samples of achenes from each head to count how many of the achenes were pollinated.
