This morning started with Jared and I doing an inventory of the Hesperostipa spartea (porcupine grass) in experimental plot 1. We are interested in determining the fitness of each H. spartea. We went to each plant found during a systematic search. We determined how many seeds were present on each culm of each plant. We counted the number of full (having a viable seed), inviable (having a seed that would not reproduce), or unknown (a glume that was empty, or peduncle that had no glume) seeds for each plant and harvested ripe seeds for later plantings. We found one studly plant that had 14 culms and 58 seeds that were ready to harvest! After experimenting with several methods of tying the immature awns together (to make sure we could find the seeds once they are mature and drop), we determined the most effective way to retain the seeds is to tie the awns together with twist ties. We hope the twist tie method allows us to harvest seeds before they disperse. We tried several other methods for tying the awns together (tying the awns to the stem, tying the awns to a red flag, and tying the awns together) but twist ties appear to work the best. In the afternoon I tagged my first Echinacea (plant 1980)!

It’s been a day full of giddy excitement for Team Echinacea. Not only was it a team member’s birthday, but on our first trip to the remnants we found the first flowering head of the season. If you look carefully at the picture below you can see the first style on the bottom right.
This plant is number 1414, first tagged in 1997 in the KJ remnant. The upper florets on 1414 are not typical in form, and appear to be diseased. Bets are still on for the first flowering head in the experimental plots. -Claire Hello! My name is Keaton Holsinger and I am honored to be a member of the 2014 Team Echinacea. If you would like to find out more about me, check out my background at website. Also, just for fun, here is a picture of a fish I caught!
Hello Floggers! My name is Claire Ellwanger and I’m excited to be a part of Team Echinacea this summer. Since graduating from Bowdoin College in 2012 I’ve spent the past two years gaining experience in the field of plant biology and conservation in Maine, California, and Puerto Rico. I’m already enjoying time in the mid-west getting to know prairie plants and how their reproductive success is impacted by habitat fragmentation. More about me and my research this summer can be found on the Echinacea Project website.
These are the methods for the hawkweed removal experiment performed by Allison Grecco, Cam Shorb, Jared Beck and Elizabeth Mays in experimental plot 1. The percent basal cover of hawkweed in each quadrant is to be determined by Team Echinacea in Summer 2015.
This afternoon Claire and I struck out for Staffanson Prairie to check on the flowering status of Echinacea. Over the course of the summer, we will be monitoring the phenology of mapped plants at Staffanson to examine how fire influences mating opportunities and reproductive success in Echinacea populations. We found several plants getting ready to flower (including Echinacea #7553 photographed by Claire) but we are still a week away from floret emergence. Although Echinacea bracts were closed tight, we did find numerous other species in bloom such as Wood Lily (Lilium philadelphicum), Yellow Sundrops (Calylophus serrulatus), Prairie phlox (Phlox pilosa), Prairie Alumroot (Heuchera richardsonii), Silverleaf Scurfpea (Pediomelum argophyllum but always Psoralea to me), and the aptly named Mountain Death Camas (Zigadenus elegans). I graduated from Jefferson High School in June, and I will be attending the University of Minnesota – Twin Cities next fall. This is my first real research experience but last summer I spent some time with the Minnesota Department of Natural Resources and the University of St. Thomas doing some work with stable isotope ecology. This summer I plan to study pollen longevity and determine a method for long term storage of the pollen. I am also very excited to work with other team members and help with their projects. I am incredibly excited to be a member of Team Echinacea 2014, I think it is going to be an amazing experience and I am going to be working with some very awesome people! you can learn more about me at my page on the Echinacea Project website. My Saturday began with some casual sketching as a way to get more familiar with some of the common pollinators found on E. angustifolia. Fun fact: illustrating correct wing venation is very arduous process.
I then joined everyone else for a team brunch at the local diner. Once all members of Team Echinacea were sufficiently stuffed with pancakes, eggs, hash browns and other belly-expanding foods, 62.5% of Team Echinacea set sail for Fargo to attend the 37th Scandinavian Hjemkomst/ Annual Midwest Viking Festival! There were battle demonstrations, informative exhibits, and plenty of Scandinavian crafts, foods, and performers. A team favorite was the Hopperstad Stave Church Replica that Cam sketched with the precision of a seasoned Viking-aficionado (Figure 19.F).
The day ended was some delicious Fettuccini Alfredo prepared by Keaton and we all fell asleep full of both food and new knowledge! Skal! (Cheers in Norwegian from the Old Norse word for cup) -Maureen Page … to pull weeds, that is! Today Jared, Allie, Cam and I designed an experiment to determine the most effective and efficient way to terminate hawkweed from the SW corner of Experimental Plot 1 (P1). We created a 4m x 4m plot with 16, 1m quadrants. We originally wanted to have four treatments of: 1. Hand weeding 2. Hand weeding with tool 3. Painting round-up solution on peduncles after cutting off the flowering heads 4. Painting round-up on one leaf per basal rosette. Due to time restraints we had a fifth treatment: 5. No hawkweed removal (as a control). We learned a lot about experimental design while getting our hands dirty! In the afternoon we removed the rest of the hawkweed that was outside the plot and searched multiple rows in P1 for Stipa, affectionately known as “Porcupine Grass”. At least it’s not as smelly as the porcupines in the Colorado Springs Zoo! (Title of flog post inspiration courtesy of Rebecca Blacks infamous song “Friday”.) We started out the day doing what we do best: searching for seedlings in Experimental Plot 8 (a.k.a. Q2). Having braved formidable winds to plant them late last October, Stuart, Gretel, and Ruth were visibly relieved to see them pop up this spring. Since last week Team Echinacea has been diligently tracking down each seedling and “naming” them with colored toothpicks and row location coordinates, accurate to one centimeter. In the afternoon we located and counted Echinacea in the recruitment experiment, a continuation of the project described in this paper. The procedure is really fun: we find the boundaries of the plots with metal detectors, triangulate points, then search within an area exactly the size of a regulation 175-gram Disc-craft Ultra Star disc (a.k.a. frisbee). Go CUT! The best part of the day was tagging my first Echinacea. Maybe it just lost its old tag, but I like to think this is the first time this plant has ever born the silver badge. Sometime 10-12 years ago, this seed was planted. Now that it is finally about to flower, it has the honor of going down in history in the databases of the Echinacea Project, living out the rest of its life in the service of science. This 23rd of June, 3.65 m from the southwest corner and 0.79 m from the southeast corner of the northeast plot in Recruit 9, I named a flowerstalk “19061.” Isn’t it beautiful?
Doesn’t the flower head look ripe? Stuart says we may start to see flowering as early as the end of this week!
Eventually the time came to leave my new friend and join the rest of the team. This is where they were:
(Can you spot the team?) A nice day is Douglas County is a very nice day. |
