Research update: May 2017

May is over and summer is officially here! In the past, this has meant that it’s time for me to get up on the green roofs and start collecting data again. But not this year.

ksiazek mikenas penstemon hirsutus green roof summer blooming pollination diversity

Penstemon hirsutus or “hairy beardtongue,” is one of the species that I am studying for my dissertation. It started blooming on a green roof by the end of May. My research found that although the genetic diversity of this population is not very high, the flowers still get visited by a lot of pollinators. Pollinator visits can help keep genetic diversity from becoming too low – this is a good sign for the Penstemon.

This past May, my research schedule was a bit different because I have been busy trying to finish analyzing my data and writing up my results. I’m in the processes of finishing my Ph.D. and wanted to defend my dissertation by the end of the month. So instead of collecting new data, I looked at what I had already gathered and worked hard on uncovering the story that the data had to tell. I’m happy to say that by the end of the month I had written a story of how green roofs could be used for conservation of native plants. I then presented the nearly 200 pages of information to my defense committee in a 30-minute oral presentation and they asked me questions about my research for about 3 hours. All in all, it was a long process, but it was also very exciting to be able to look back at all the research that I’ve done over the past 6 years and finally be able to say that I have some conclusions and recommendations. The committee decided that I passed this test, which was excellent news! I still have some revisions that I need to incorporate into my overall dissertation and then I’ll continue working on getting my research published in peer-reviewed journals. This will take some time. But I’ll have all the revisions done so I get to be called “Dr.” this year, which was my goal.

The first slide of my dissertation defense. Can green roofs provide habitat for native plant species? In a word, YES! (But the other thousands of words in my dissertation also say that “It’s complicated” …)

As I transition from research for my dissertation to a new career path, there is no new research or data collection. In fact, I’ll be taking some time off this summer from both the research and the blog posts. I’m sure it will be strange not visiting some of the green roofs that I’ve been going to year after year. But I’m also sure that I’ll enjoy some of the cooler temperatures on the ground when the sun is really beating down on the hot, hot rooftops. After tending to some of my sites for 4 years now, it’s time to see what they do on their own.

Happy summer to all! Go visit a green roof this season. I’ll talk to you again in September!

My green roof plots at the Chicago Botanic Garden continue to grow and are looking good to start their fifth summer season. Without monitoring or data collection this year, it will be interesting to see how they do. Good luck my little plants!

Research update: March/April 2017

ksiazek mikenas green roof prairie smoke Chicago

Prairie smoke (Geum triflorum) is one of the first plants that blooms in the spring. It was flowering on this green roof in Chicago among the short leaves of other native plants. This rooftop will look like a fully-functioning prairie in a couple months!

Welcome spring! It’s time for the plants on the green roof to wake up from their dormancy and start growing once again. It’s wonderful to see that some of the native prairie species that I planted back in 2012-2014 are still alive and doing well on the green roofs around Chicago. Though most of them are still tiny, I think they’ve been enjoying the milder temperatures and lots of rain. By mid-summer, things will look quite different!

Even though I’m not collecting data this year, my experimental prairies are still going strong on the green roofs. You can see the plants starting to emerge in the strip along the lower right corner of the photo.

The native nodding onions (Allium cernuum) have survived another winter and are emerging in the green roof trays, along with some prickly pear cactus (Opuntia humifusa)

I’m finished collecting data on the green roofs for now and these past months I’ve mostly been analyzing my data to see what patterns emerge and writing about my results. I’ll be finishing my graduate program this year and I’ve got enough data to write about for my dissertation. It already feels a bit strange not to go back to some of the same green roof sites that I’ve been visiting year after year, but I’m sure that my post-graduation plans will involve green roofs in some way so I know I won’t be away for too long. It’s also kind of nice to just go to the green roofs and appreciate their beauty without all the strenuous data collection!

ksiazek mikenas growing up in the city book children

For part of a virtual conference, I filmed myself talking about my children’s activity book “Growing UP in the City: A Book About Green Roofs.” The video was featured during the month of April.

Other than data analysis and writing, I was also involved in a conference this spring. Not a typical conference this time, but a “virtual summit” which is a type of conference that is 100% online. It’s the first time I’ve ever been a presenter at a virtual conference and it was quite a different experience. I was invited by to speak about the children’s activity book I wrote for their 2017 Green Roofs and Wall of the World 2017 Virtual Summit. Being a speaker involved writing a script, videotaping myself, and collecting video clips and photos of people using the book. Thankfully, the organizers of the conference helped produce a nice video. Now people who are registered for the summit can watch it online to learn all about how and why my coauthor and I designed this fun book. There was also a live question and answer session about the book, which is similar to the Q&A sessions at the end of regular presentations in live conferences. All in all, this virtual presentation was a neat way to talk about some of my work with people from around the world. And I didn’t even have to leave my house!

ksiazek mikenas film WTTW green roof Notebaert urban nature

Back in August, I was filmed for the video series, Urban Nature. In March 2017, the video was released. Check it out!

Speaking of videos, in March WTTW Chicago put out the video series for which I was filmed back in August. The series of videos are all about urban nature and they include a lot of really interesting stories! The one I’m in is called Rooftop Refuges and you can watch it by clicking here. It starts off in New York where researchers are looking at how birds use green roofs. My part about native plants ended up being pretty short, considering the hours of filming (and extreme sweating in over 100 degrees F heat), but I think it came out very well. Be sure to take a look – I’m sure you’ll learn something new! There is also a short article about the video series that you can read by clicking here. Enjoy!
