Research update: June/July 2016

Well, as you can see, my “monthly” research updates are a little bit behind and this post is extra long. It seems like with all the work to be done outdoors and out of town, it’s been hard to sit down to write about it all. But as I look back at June and July it’s exciting to remember all that has happened.

Ratibida pinnata (gray-headed coneflower) blooms beautifully in one of my green roof plots.

First, I am happy to say that an article I wrote about biodiversity on green roofs was published in Wild Seed Magazine, a publication from the Maine-based non-profit Wild Seed Project. I won’t say too much about the article, other than you should click HERE to read it and if you should click on the link above if you want to get a copy of the whole magazine (which includes an article from the amazing naturalist Doug Tallamy and is really good).

The Dalea purpurea (purple prairie clover) was blooming on the green roofs in June and attracting pollinators!

As far as research goes, June started out with data collection on the green roofs. I’m continuing to measure the plants in the prairie mixes that I planted back in 2012 and at the beginning of the summer, things looked a little sparse but promising. After a pretty rainy summer, some of the same plots are actually pretty lush and there are many species of plants that are flowering in beautiful displays of yellow, white, and purple flowers. It’s impossible to capture them all with my cell phone’s camera, but believe me when I tell you that they are lots of pollinators coming to visit my plants too! When I’m back to more indoor work in the fall I’ll analyze the data to look for significant patterns. So far, it looks like the species from the prairies that are most similar to green roofs are the ones that are growing the best. It’s really exciting for me to know that when I stop collecting the data for this experiment, there will be some little prairies on the green roofs for years to come.

I'm continuing to measure the amount of water that the different plant combinations capture and hold throughout the day.

My experiment measuring water capture continues as does my collection of weeds from the green roof trays to determine how good the prairie plants are at resisting weeds compared to succulent plants. Everything is going well with those experiments except for the fact that a surprise thunderstorm messed up some of my data and I have to do one part of the experiment over again. I’m not happy about that, but that’s just how botanical research goes sometimes. I’ve got my fingers crossed for some rain-free days in early August.

Weighing the weeds continues. So far it looks like the succulent Sedum plants are the best at preventing weeds.

Back to the ground - I finally found the Penstemon plants I was looking for in the shortgrass prairies. It's fun to go back to the sites that I'm trying to replicate on the roof and appreciate how special these habitats are.

Pollinators are visiting my plants on the green roofs! It's exciting to see evidence of the ecological relationships that I was hoping to support.

In addition to the green roofs, I also went to a couple prairie remnants southwest of Chicago to collect some plant tissue. I’ve been putting my lab work on pause for the summer, but if you remember, one of my experiments is to measure pollen movement between green roofs using a paternity study. Well, I’m finding that it’s really hard to distinguish one “dad” plant from another because the dads have very similar DNA. I think this is because the nursery where I got the experimental plants wasn’t using a diverse mix of parental plants but I want to make sure that the plants you’d find in nature would actually have more diversity in their DNA. To do this, I need DNA from plants in their natural habitat – and this is what led me to collect leaves from the shortgrass prairies on a steamy Friday in June. I was hoping to find three whole fields full of my target species of Penstemon plants but, after hours of searching, I only found two small patches. For now, I’ve collected the leaf tissue and it’s drying in the lab. I’ll get back to that when it’s time to get back to the lab in the fall.

Lespedeza capitata (roundhead bushclover) blooms beautifully in one of my plots on a green roof.

It’s actually hard to believe that I was able to collect so many data when I look at all the times I was out of town, talking about research rather than actually conducting it. But through these experiences, I met a lot of wonderful people that are also interested in plant and animal conservation, urban ecology, and science education & communication – my favorite things! At the beginning of June, I was thrilled to be selected as a participant in ComSciCon in Cambridge, MA. This is a graduate student-run conference for other graduate students in science who are interested in engaging with non-scientific audiences. The fellow attendees I met are involved in some amazing endeavors, including documentary filmmaking, graphic design, afterschool programs, and policy advocacy. I could go on for many paragraphs about how awesome these folks were, but I’ll just summarize by saying that I was truly inspired. I started writing a piece about green roofs to be submitted to a children’s magazine while I was there and I’m hoping to get it published this year – stay tuned.

After my trip to the East coast, I headed out west to Colorado Spring to participate as a botanist mentor in a workshop called Digging Deeper. As a mentor, I got to meet high school teachers that teach their students about plants together with plant scientists in a program called Planting Science. As a previous high school science teacher and current scientist, it was really fun to try and figure out the best ways to teach teenagers about plants in an exciting and engaging way. In the fall, I’ll be a mentor to a couple student groups and through video conferences and email messages, we’ll help them design their own experiments to learn about botany – how cool is that?

A spontaneous Penstemon plant (the one I'm studying in a different experiment) has germinated and flowered in my experimental green roof trays. I'm glad to see that this native species does so well on green roofs.

I had a couple more trips a little closer to home too. The first one was to Michigan to share my research and meet the new cohort of Northwestern University Presidential Fellows. Wow. More amazing people doing some fascinating research from applications of nanofluids and deciphering the genetic code to impacts of affirmative action on hiring practices in the NFL. The second trip was to Wisconsin to give a presentation at the North American Congress of the Society for Conservation Biology. I’m pleased that my presentation about my green roof research was well received and I even got to meet some other professional from the Chicago area that work with trees, wildlife, and the human-nature connection. As I finish the last year of data collection for my dissertation, it’s really helpful to start thinking more about the broad applications of my research and how the things I’ve learned so far might be applied to other fields when graduate school is complete.

As a final note, in addition to the research and trips, I also got married in July! Did you notice the new name of the site? I may have a new name but the research is still pretty much the same – I don’t think the plants noticed at all!

Up next month: Field work, lab work, data analysis, writing, and even maybe a TV appearance!
