Once again, August was a busy month, filled with field work, lab work and even a conference! It’s fun to look back and see what I was able to accomplish.
The month started with completion of the vegetation surveys that I was conducting on 3 of the green roofs in the Chicago area. These vegetation surveys allow me to measure the height, coverage and reproduction ability of the various plants that I planted on the green roof. With the rainy summer we’ve been having in Chicago, most of the plants are doing quite well and my little plots continue to look like mini-prairies. Originally, August was supposed to be the last time that I had to take these measurements. But my mini-prairies are looking so good (and I’m such a botanist!) that I want to come back next year and measure them again. We’ll see if that’s still the plan come 2016.
Speaking of prairies, I also visited an actual prairie for my research (on the ground this time, as opposed to a rooftop). Two interns from the Chicago Botanic Garden and I took a trip to a large prairie in central Illinois to collect leaf tissue from the same species of plant that I’m studying on the roofs. I am looking at how pollen movement in this species can help increase the genetic diversity of green roof populations. But I wanted to know what the genetic diversity of this species is like in natural populations, in real prairies. So we collected leaf tissue from a natural population, extracted the DNA from the leaf cells, and are now working in the lab to measure the diversity. This is a work in progress, so stay tuned for the results. If anything, it was neat to see the plant species I’m working with in its natural habitat.
In addition to collecting lots of data, I was also fortunate to be asked to present some of the overall findings of my research so far. I’m still working on collecting some more data from internet sources and analyzing my results but I am beginning to find some trends with the data that I collected back on the green roofs in Germany in 2013. It seems like there are very few patterns that predict which plant species colonize green roofs and survive on them over time. It looks like each green roof is a unique place with its own community of plants and animals that live there. I was able to share these results (and others) at a special green roof session of the Ecological Society of America’s annual meeting in Baltimore, MD. And not only did I get to present my research, but I got to attend lectures and workshops where I learned about other people’s research too. It was a busy week in Baltimore and even though I came back tired, I was also inspired and excited to keep making discoveries with my own research.
And finally, in August I started to work in the lab again to continue work that I’ve been doing for about a year now. The lab was super busy with summer interns but toward the end of the month things quieted down a bit and I could claim some work space back. I’m ready to continue the work I was doing back in the spring. It’s time to find out if I can determine the father plants of all the seeds that I collected last fall and grew up into little seedlings over the winter. It’s going to be a lot of work but I’m looking forward to being a bit of a botanical detective!
