Research update: February 2017


Just a quick update here for February. Although we got no snow cover (no February snow in Chicago – can you believe it? I wonder how the green roof plants will do after this unusually warm winter!) it was still a good time to get some indoor work done. This past month, that meant more writing and lab work.



Which offspring do I have enough genetic data for? Color-coded charts help me figure out which samples I need to run next in the lab. 


My February writing mostly focused on a manuscript I’m writing about the different types of plants that survive on green roofs over long periods of time. I used some long-term plant surveys of 6 green roofs in Germany and included a plant survey I conducted on 13 green roofs in the same region when I was there back in 2013. While I was writing, I was also analyzing the collected data to see if the types of plants that arrive on green roofs right after their planted are different than those that end up staying there for a long time. I did find some differences. It turns out that weedy plants able to spread seeds and easily use resources like water and soil nutrients are common on green roofs for a few years after they are built. But later, only the species that have traits that make them tough enough to withstand the heat and drought on green roofs will remain. It took a long time to figure this out and write up the manuscript. I now have a draft. I’ll keep working on this manuscript and will hopefully be able to submit it to a journal for publication review sometime this spring.


More little test tubes of DNA and more genetic sequencing in the lab. I’m getting more data every month but still have more to collect.

In between writing, I also got in a little bit of work in the genetics lab. I’m still trying to figure out how much genetic diversity the plants on the green roofs have. When I have some more data, I’ll figure out if this is similar to plants that have been living on the ground for a long time. I’m hypothesizing that the plants on the green roofs don’t have as much genetic diversity because there are fewer pollinators there so the plants that can breed with themselves, do. I’ve been collecting the data for this experiment for a while now. I think I’m getting closer but will still be spending more time over the next month or two working with machines in the lab that help me make copies of my plants’ DNA and then determine their genetic sequences.

Other than the writing and lab work, I did get to present some of my work at a local conference in February. The Chicagoland conference was called WildThings and brought together over 1,000 people from the area who are interested in conserving the wild plants, animals, and other critters that we share our space with. The presentation went well and the presentations that I got to see were very interesting too. I especially liked learning more about conservation efforts that are happening in the corner of the world that I call home.

Next month: more writing and lab work!
