Predicting how global change will alter ecosystems is a central challenge in ecology. Soil fungi are major drivers of ecosystem processes, and they respond to global change by reassembling communities and altering activity. In this session, we consider how multiple global changes – including climate, nitrogen deposition, fire, and biotic invasions – affect soil fungal communities and functions. Some ecosystem processes rely heavily upon soil fungi. For example, primary production depends on mycorrhizal fungi, which supply nutrients required for growth to plants. Mycorrhizal species vary how efficiently they take up and transfer soil nutrients to plants. Variation in how mycorrhizal fungal species respond to global change could therefore have an effect on ecosystem net primary productivity. Similarly, organic matter decomposition rates depend on the saprotrophic fungal community. Decomposition is a multi-step process and some fungal species are better equipped to decompose than others. Global changes differentially affecting saprotrophic fungal species can have downstream effects on decomposition rates and soil carbon storage. Ecosystem processes and soil fungi are intricately linked, thus, understanding how soil fungi respond to global change will increase our ability to predict whole ecosystem responses to global change. Our session goal is to reveal general patterns of soil fungal community and functional responses to global change, spanning scales from microbes to whole ecosystems as we link fungal biodiversity to ecosystem nutrient and energy fluxes in a changing world.
