Cover image: Populus angustifolia along the Lamar River in Lamar Valley, Yellowstone National Park, Wyoming. Populus angustifolia is a model system for understanding the linkage and feedbacks among plants, the soil microbiome, and ecosystem function. These individual level Plant–Soil interactions vary among populations to link local and landscape level scales across the western United States. These interactions affect plant phenotypes, like phenology and productivity, that are thought to be important to survival in an uncertain climatic future.
