At the Carleton College Summer Research Symposium on October 26th, I presented a poster on my work on the aphid addition/exclusion experiment. Over the summer, I administered the aphid addition and exclusion treatments for the experiment and collected data on leaf senescence and herbivory on plants in the study. Since August, I have been developing an aster model in R to analyze differences in fitness between these two experimental groups. Preparing the aster model for my project was quite a bit of work, but I learned more about R, statistical analysis, and plant-herbivore interactions in the process. Interestingly, Aphis echinaceae has not had an impact on plant fitness over the 8 years of the study.
I am excited to see how the experiment progresses in the coming years, and how the addition of data on seed set affects the results of future fitness models. Quite a few visitors to the symposium were also interested in the results of my analysis and my experience working with the aphids. It was a pleasure to represent the Echinacea Project at Carleton and to have a chance to share the fantastic work the team did over the summer.
