The team updated and analyzed past climate data in Alaska and northeast Ohio to examine the response of trees to various environmental factors. They reported their findings to their various clients including Dr. Ben Gaglioti of University of Alaska Fairbanks, Dr. Lauren Vargo, a Wooster alum and a glaciologist studying in New Zealand, TRAYLS, and Secrest Arboretum.

This project was made possible by financial support from the following organizations: The Sherman-Fairchild Foundation and The Luce Foundation.

Members of Tree Ring Analysis will be online to field comments on Nov. 5 from 3:30pm-5:30pm.

  1. WOW! This was really interesting – I had no idea this was going on. Sounds like you guys did some really good work.

  2. Great presentation, everyone! I hope you all enjoyed working in the lab this summer despite being socially distanced. Mazvita, I’m curious about your conclusions regarding the negative correlations of Mountain Hemlock ring width and temperature. Why does a carbon storage imbalance, specifically the decrease in carbon storage with warming temperatures, influence what time of day respiration occurs?

    1. Thank you for the comment, Alexis. When I was taking part in the research experience, I was asking myself the same question too. With the help of my advisors Dr. Wiles and Dr. Gaglioti, I found that during the day, the primary process for the trees is photosynthesis, and at night it is evapotranspiration. So because of warming, we hypothesized that there would be an increase in cloud cover in this area ( using the Clausius-Clapeyron relationship). Hence, photosynthesis is reduced; however, there will be increased evapotranspiration at night because of the increasing temperatures. This then leads to the imbalance at night because of the net loss in the tree carbon storage. So it is more of the temperatures influencing the carbon storage imbalance. Further studies are required, though, to confirm this theory.

  3. Mazvita, Shrusti and Fred. It was so cool to follow the work that you did this summer. Thank you for your enthusiasm for the various aspects of the AMRE program. We loved having this project be part of AMRE. Your ability to focus so well in the incredibly unfamiliar environment of a remote research experience is a real strength and will be an important skill to use for your next opportunities. I hope your year is going well!

    1. Thank you, Dr. Ramsay, for the research experience. I think I can speak for my group and say that we truly enjoyed the experience and we will continue to use the skills we learned during the program.

  4. Fred, Shrusti and Mazvita,
    It was so fun working with you this summer and learning about your interesting work. Well done!

    1. Thank you, Vikki; we enjoyed working with you and hope we can work together again in the future!

  5. Fred, Shrusti, and Mazvita,
    Thank you for this really interesting presentation. I’m sure you gained great skills working together in the remote environment. I especially love that you were able to network with academics across the country.

    1. Thank you for watching our presentation; we truly appreciate it. Yes, we learned many skills, both hard and soft skills, particularly how to maneuver the remote world. Yes, it was difficult at first, but with our advisors and program coordinators’ guidance, we learned how to communicate and work all over the country!

    1. Thank you so much for the assistance in the program, Dr. Wiles! Yes, indeed, we will keep working hard while enjoying the process and rewards of the work.

  6. Thank you for sharing your work. It sounds like a great research experience. Has this work inspired what types of focuses or areas of research you plan to pursue in the future?

    1. Thank you so much! I’ve become a lot more interested in dendrochronology after working on this project and using the fundamentals of dendrochronology to predict future climate patterns and events, as well as building more accurate historical records is something I hope to continue doing in the future. Since I am interested in how climate and politics intersect, I look forward to using dendrochronology to make more accurate models to combat the climate crisis and using that to mitigate the negative impact on marginalized communities.
