The competition continues..

Over the past few weeks, Elymus canadensis and Bromus Kalmii have taken to the plots for a battle of resources. When I initially began this experiment, I hypothesized that Panicum virgatum would take the lead, since it develops a ribosomal root system and is known to be an aggressive prairie species. However, out of 500 seeds, only 1 P. virgatum has germinated and sprouted. For that reason, I’ve decided to eliminate P. virgatum from the data analysis. Although, I have planted the lonely P. virgatum so that it can later be transplanted to the prairies of Minnesota. I later suspected that E. canadensis would take the lead in sprouting. However, B. kalmii has currently overthrown the number of germination/sprouting. There are still a few weeks to go with this experiment before analyzing the data collected on height. With that said, it could go either way. The grasses are growing taller and faster than any of us expected. I take measurements weekly and can already conclude that competition is occurring. The leading height in each treatment varies, indicating that one of the species is achieving more resources than the other. More updates and photos to come!

Sincerely,

Danielle
