My research project is concerned with both biotic and abiotic ecological factors that are indicators of aspen tree health. The rates of leaf colour change and leaf loss are important factors underpinning my research, as these rates are partly based on soil moisture and thus will serve as a proxy for tree health. Another point of knowledge important in my study is the pH requirements of a particular species of tree. Finally, the predictor variable in my research (location of the trees on a hill, thus an elevation gradient) is the primary abiotic factor my hypothesis is based on. I am choosing to focus on the ecological processes affecting soil moisture content along this environmental gradient.
Thus, my study utilizes theories on tree health as it relates to soil moisture content variability, pH, and elevation topography. Additionally, my research touches on the biotic processes of water uptake by tree roots, leaf colour change, and leaf loss.
Three key terms I would use to describe my research project are: soil moisture content, elevation gradient, and tree health.
