Stress caused by invasive species can shift how plants interact with soil microbial communities. Plant root exudates mediate numerous carbon and nutrient exchanges between the plant and soil community, which are important for individual plants and overall forest health. This includes potential changes in soil organic matter (SOM) turnover, composition, and storage. I will measure the effects of the hemlock woolly adelgid (HWA) infestation on root exudate quantity and composition, changes in ectomycorrhizal fungi biomass, and subsequent impacts on SOM across varying growth stages of eastern hemlock. This work will help identify HWA-driven changes in plant-soil feedbacks and the potential impacts on ecosystem carbon cycling.
