A time for new beginnings

echsmall.jpg

Hello, Echinacea lovers–

I’m Amanda Gallinat, a recent grad of Carleton College and brand new field assistant to the Echinacea project. After a quick transition from Northfield to K-Town (Kensington, to those of you who don’t live here) I am finally settling into the daily routine of seedling searches, lunch, and more seedling searches.

On Monday we paid a visit to Staffenson Prairie and memorized the scientific and common name of each plant species we saw. Just kidding! We did get an idea of the general composition of the prairie, as broken down into four groups: C3 grasses, C4 grasses, legumes and forbs. I managed to leave with the ability to identify a large handful of species, and I’ll be sure to update the Flog with my progress in learning all the rest!

Over the past few days, we’ve focused a lot of our energy on seedling searches, and it seems as though we newbies are really getting the hang of the procedure. So far we haven’t searched any sites brimming with seedlings, but we have all seen some fine examples and each group has had the life-affirming experience of finding and identifying a seedling, if only once.

We’ve also spent some quality time discussing independent project ideas. My primary area of interest is plant-pollinator interactions, and I am excited to spend this summer investigating how the diversity of pollen carried by pollinators differs between remnant sizes (design details will be posted soon, so check in!). This should fit well with three other independent projects relating to competition for pollination, and might give us insight into why an increased frequency of pollinator visitation in isolated populations of Echinacea does not correlate with an increased seed set. Think we can solve the mystery? Stay tuned for updates…

If you have any questions or words of encouragement, feel free to leave them in the comments!

You can call me “M”

Hello everyone! My name is Mimi Jenkins and I’m an REU student with Chicago Botanic Gardens. I am from Pittsburgh, PA where I am a senior (one more semester!) at the University of Pittsburgh double majoring in Environmental studies and French lang/lit and a certificate in Global studies. This is my first real experience spending more than one day in the Midwest and I love it so far. The wetlands and prairies out here are gorgeous and I feel very lucky to be experiencing a new and exciting place and working with such an interesting group of people on such a worthwhile and fascinating project. I have never been on such a flat land or in such a small town, but the flat topography makes for nice biking (hoping I can get my hands on a bike soon!) and the small town is a nice break from the city for the summer. I arrived in Chicago two weeks ago and after an introductory week for the REU program doing lab work on soil samples and such (not my cup o’ tea), I met Stuart, took pictures with the help of Jake Friedman of some of the Echinacea pollinators and visitors that are pinned and in boxes at CBG, and did a little research on the nesting habits of bees.

Here is the protocol we came up with for the picture-taking:Protocol for Taking Pictures of Insect Specimens.docx

Here is some of the info I found on nesting of bees commonly found on Echinacea:
Echinacea Pollinators nesting.docx

I am really excited about this field season and I wish I could stay longer! I am really interested in improving my plant and bee identification skills on the prairie, as well as my knowledge of statistics in analyzing data and applied ecology in general. I also hope that this experience will help me to hone in on what I want to focus on for graduate schools in a year or two. I am currently trying to think about what exactly I would like to focus on because everything sounds so cool but I am limited to less than 6 weeks of research so it must be a pretty precise question, such as: does one family or species of bee act as a more effective pollinator for Echinacea than others using the style persistence method, or what co-flowering species are the pollinators pollinating that also land on Echinacea by observing pollinators on other plants or looking at foreign pollen on Echinacea heads. I would like to work in the common garden and in remnant populations to get a good sense of how these questions might differ depending on the community diversity of the remnant and the health of the Echinacea population.
I went out wandering yesterday and I think some of the locals thought I was a crazy person for walking on the side of the road but until I can bike, I will explore by foot. I turned onto the first dirt road on the right off of Kensington Ave and found this pretty hillside prairie remnant at the end of the road. I wanted to go further, but the electric fence kept me from continuing. I saw a patch of something yellow flowering off in the distance. Along the path of the dirt road between two corn fields I saw what I think was brome grass, prairie rose, common milkweed, alfalfa and clover, and some others like thistles that I couldn’t identify. I saw a big white bird that Stuart told me today was an American egret. I also saw some more of those cool turquoise dragonflies that are in the common garden. I regret not bringing my camera with me because the view at the end of the dirt road was so pretty–there were relatively few trees and you could gently rolling green hills for miles.

a good year for cuckoos

I heard a yellow-billed cuckoo from the farm house today. It was south of the farm house, perhaps in the South Field.

I went down to the common garden experimental plot around 9:30 or so. I didn’t see or hear any black-billed cuckoos.

a good day for cuckoos

My family drove from IL to MN on Thursday. We arrived late in the evening and didn’t have that much time to look around, but we did see a lot of tent caterpillars.

First thing Friday morning I went out to the common garden. I flagged plants and planned to mow a few walking paths because Caroline was coming to figure out which plants were going to flower in the inb1 experiment. I paused while mowing and heard a black-billed cuckoo. Then I noticed that there were a few flying around and I heard several calling. I am positive that there were six birds within earshot, but I think there may have been eight. I have never seen more than one a time. It was really neat. There was one calling east of the common Garden and three calling from the shrubs and boxelders along the west edge of the CG. They also flew across the corn field to shrubs next to the wetland west of the CG. Two birds were cavorting in the ditch and flew right next to me on their way to the cottonwood at the NW corner of the CG. Very cool!

It is good to be back in Minnesota. The common garden looks fine. The kids are in their element. I can’t wait for the field season to start! But first: unpack, set up computers, clean the Hjelm house, bring beds to Kensington, go to graduation party, get sleep.

The township supervisors (Joe Martinson, Carl Hamen, and Ken Anderson) drove by inspecting ditches. They are planning to cut trees on the township road N of the driveway because someone can’t get their combine through.

plants flagged at lf site for seedling search

I flagged 20 spots at the landfill site last Saturday. 18 are centered on Echinacea plants that flowered last year (blue flags). 2 are random locations (orange flags). Amy and Caroline are going there tomorrow to search for seedlings.

I noted other plants that were flowering on the east hill:
Zizia aurea
Lithospermum canescens
Sisyrinchium (1 pla)
Viola pedatifida
Astragalus sp.
Pediomelum esculentum – just about to start
Geum triflorum – done
Commandra umbellata – mostly done

On the west hill I noted these:
Senecio (1 pla)
Taraxacum officinale
Antennaria neglecta – done

Locating Research Populations

This is my first trip up to Minnesota this year. My goal is to locate populations of the species I want to work on this summer.

I spent yesterday afternoon and this morning at Glacial Lakes State Park in Pope County. There was quite a bit blooming along the trail. There was a fairly common Viola with deeply divided leaves, unfortunately not the one I want to work with. I saw at least three Astragalus species, two of which are past their prime and another low-growing species with white flowers. Only a few of the white-flowered plants were in bloom. Geum triflorum is already in fruit as well as Antennaria, and Zizia is just starting to flower. There were two Lithospermums throughout the park, both common. One had lemon yellow crenulate corollas and the other had dark yellow flowers and darker foliage. I saw two Carex, one really short one and a taller one, both in bloom. I believe neither are the species I’m looking for. There was a lot of a white flowered caryoph, which got me excited because I thought it might be Silene antirrhina, but it wasn’t. I’m not sure what species it is, let alone genus. I stayed at Baby Lake campground last night because there had been a collection of Lomatium orientale near Baby Lake, but I had no luck in locating any plants. There are some dry hills a little farther from the trail that I wish I could explore, because they seem like the kind of habitat in which I might find a Lomatium.

This morning and early afternoon I spent around the farm and at some roadside sites. I checked out a gravel mine for Lomatium, but I didn’t find any. There was very little vegetation at all there. I did have luck finding the spot at Loeffler’s corner where Stuart said there would be some Stipa comata, but the clumps haven’t started forming inflorescences yet. Hegg Lake has mostly been burned, so my visit there was short. I did find a small hill near the road that escaped the burn. Nothing up there interested me except some Stipa, which is probably S. spartea and not S. comata. Overall, it’s been a disappointing day, especially because I couldn’t get into landfill. Perhaps tomorrow will be more fruitful.

spring!

I drove up to Minnesota from Illinois on Monday night, May 4. I felt like I drove backward in time about two weeks. The trees weren’t green, the brome wasn’t above the thatch, and no warblers were in the yard of the farm. When I left on Friday, it felt like spring had progressed more than a week. Maybe I was just happy I got everything done on the to do list.

Late morning on Tuesday it was raining, so Amy, Brad, and I went into Kensington to look at place to rent for the summer. We met the owner and her daughter at the former Kensington Town Hall. The main room of the building is a basketball court–it is a large space. The family had added rooms and amenities and lived there for several years. The place was too expensive to heat during the winter (in spite of the newly insulated ceiling and new windows), so they moved elsewhere and are looking to sell the Town Hall. It will be a great space for Team Echinacea this summer, so we rented it.

It was still quite wet at 1. We ate lunch at the Kensington Cafe.

Amy, Brad, and I mowed fire breaks for the Echinacea seedling recruitment experiment. The experimental plots are on State land: Kensington Duck Refuge (2 plots), Eng Lake WMA (1 plot), and Hegg Lake WMA (5 plots). We got all breaks mowed and flagged. It was much more efficient with three than with one. We even had two mowers! The plots are ready for the DNR crew to burn!

We have 4 other experiment going at Hegg Lake WMA. Jennifer’s phenology common garden experiment is in the unit scheduled to be burned this spring. The fiberglass poles on the E side are gone. Someone drove a truck across the S edge. We found one flag at the S edge of the plot. It was labeled 39–we saw no plants nearby. Amy and I looked for plants in the SW corner. There was a pole there, so we thought we could find where plants should be. We easily found a plant in each of the three spots we looked–the 2 S-most spots in row 1 and the S-most spot in Row 2. They were 3 – 5 cm tall. All in all, the plot looks good. A burn will help the plants. We planted ~3700 seedlings in 2006 and found 2997 still alive in 2008. I suspect shading has contributed to the mortality. A burn will be good.

In the central burn unit at Hegg Lake (burned in spring 2008) three experiment were planted. These experiments all investigate how the genetic composition of seeds influences their recruitment. In all three experiments seeds were broadcast over vegetation last November. Amy found seedlings in her local adaptation experiment. (!) This plot has seeds from Minnesota (very local), E. South Dakota, and W. South Dakota. Only cotyledons were present so far, no true leaves yet. I wonder if there are differences in the timing of emergence of seeds from these places. We didn’t see seedling in the rescue experiment–all local seeds, F1. We only briefly looked at Caroline’s experiment–F2 generation of local seeds.

We peeked at a small dense remnant patch of Echinacea. It burned last year and maybe a dozen plants flowered. We saw quite a few seedlings. Sometimes it is so easy to spot them.

It turned out to be a good day. The only drawback was that I forgot to bring my key to the farmhouse. I brought my huge ring of keys, but forgot that I had lent out that key last fall. So, instead of spending the night, I drove back to MPLS.

Had good meetings with Ruth and Caroline on Wednesday and then drove back up to the farm on TH with my Dad. He brought his key.

I accomplished all items on the “to do” list. But just walking around I saw a million other things to do that weren’t on the list. Sigh.

The Common Garden looks good. I cut sumac on the E side with the brush cutter. We girdled and cut some trees on the E side, mostly ash and a few box elders. They were shading the E side. I hand broadcast 1/3 of a grocery bag of Bouteloua curtipendula seed (a little bit of Schizachyrium scoparium too) in both units. Last fall I harvested 2/3 of a bag and I broadcast half of that at the end of December (brr). I saw no fresh gopher activity.

The Echinacea plants I looked at were 2 – 10 cm tall. None of them were far enough along to tell if they are going to flower.

I seeded other prairie seeds in the ditch, near the Hjelm house, and in the backyard prairie garden. There were some seeds from last year. Most were collected a long time ago and had been stored in a fridge at the U of MN in preparation for planting in Spring 2003. I forgot to plant them then. We’ll see if any take.

On Friday morning I drove to Glenwood and gave a presentation to the DNR wildlife staff (Kevin, Rich, Jason, Wayne & Bob) and others on fire ecology. They asked lots of good questions. We discussed many aspects of prairie and fire ecology. The wildlife staff is the group responsible for transforming Hegg Lake from the weedy, treey, low-diversity oldfield WMA with patches of declining prairie remnants to the vibrant, well-managed grassland, wetland, and native prairie complex that it is today.

Kevin, Rich, Jason, Wayne & Bob are also the guys who burn the plots in our recruitment experiment, so I wanted to update them on the analysis that Amy and Caroline just did and tell them our new experimental design for burns. Getting all the plots burned has been a challenge in the past few years. Now that we are expecting plants to start flowering, we want to get a complete burn treatment in this spring.

We also worked in the vegetable garden. The asparagus was peeking up, garlic, and rhubarb are growing up. Peas and lettuce planted earlier this spring were just up. My Dad planted a whole lot of seeds and potatoes while I was in Glenwood. We also starting working on a new area for the vegetable garden.

Phenology notes for Megan: The only non-weedy plants I noticed in flower were Pulsatilla, Geum triflorum, Violas, and a few carices. The carices were in the lawn at the farm (probably Carex pennsylvanica, a weed, and another one). I didn’t see any prairie Carex flowering at Hegg, but they will be soon. The Violas in the lawn at the farm were well along and there were a few starting on the edges of gravel roads. V. pedatifida wasn’t flowering. Prunus aren’t yet flowering but P. americana will be soon.

Way extended field season

Amy and I were out at Hegg Lake last Tuesday and Wednesday sowing seeds for a couple of new experiments. Hard to believe there’s still fieldwork to be done in the middle of November! It seems everything was pushed late this year. On Tuesday, as we were measuring and setting up plots, we experienced about every form of precipitation: light snow and heavy, wet snow and freezing rain and good ‘ole regular rain. Luckily by Wednesday, there was little accumulation and nothing falling from the sky. We sowed my entire experiment, looking at the ability of genetically rescued plants to recruit new individuals to a population, and one third of Amy’s, which examines both local adaptation and the relative potential of different populations to act as genetic rescuers. Here are some pictures showing ice around the edges of Hegg Lake and our attempt to get achenes right on the ground in our plots (utilizing kitchen scrubbers/mini-brooms to brush away vegetation).

Hello, all! This is Denise. =D =D

Lani and I are starting our posters. We’re doing one that targets the field work and one that targets the lab work. We’re hoping to fill it up with mostly photos like this:

Since I got back, I’ve been staying at Carey’s house. His step-mom has a garden, and guess what I recognized? ECHINACEA! Loads and loads. ^o^ Anyway, we saw a sickly plant in her garden and were hoping for some feedback as to what it could be. There’s some discoloration on the leaves and the heads don’t look too healthy as well. Here are some photos:

=( Unhappy echinacea, yes. What could it be?

Here are some other plants from another part of her garden that look much better:

Team Chicago home safe

Hi all,
Lani, Denise and I are back in Chicago safe and sound. After such a rainy start to the day overall the drive was smooth and even included a Disney sing along. My reunion with my puppy, Raven, was filled with lots of jumping and tail wagging.

Photo of Raven from before I left for Minnesota…tried to take one tonight but she was too hyper.

Ben, Lecia, and Julie, I had a great time working with all of you and I wish you the best of luck in your future ecological endeavors. Everyone else I will see you back in Chicago or in Minnesota in the near future. Have a great rest of the summer Team Echinacea and we will keep you posted on our progress here in Chicago.
Jennifer
