Research Abstract |
Our work examines the role of fungi in mediating ecosystem responses to global change. Along with bacteria and other soil biota, fungi control several critical biogeochemical processes, including plant nutrient acquisition, decomposition of dead biomass, sequestration of nutrients in living and dead fungal tissue, and release of trace gases such as methyl halides. Laboratory studies have indicated that fungal growth and physiology can respond to atmospheric chemistry, nutrient availability, and soil temperature and moisture—all of which are altered by global change. As such, fungi may feed back to affect ecosystem functions under these conditions. However, soil microbes have traditionally been considered a “black box” within natural ecosystems, in which nutrient transformations sometimes occur and sometimes do not. We have no clear idea of the specific fungal groups involved, nor do we understand their individual responses to the environment. As such, we have a limited ability to predict ecosystem-level responses to environmental variation. Several fundamental questions remain regarding the role of fungi in ecosystems. For instance, do fungal groups differ in terms of biogeochemical function? How does global change alter fungal diversity and activity? We are not even certain how long individual fungi live in natural systems, even though the answer would help us assess how quickly microbial communities might respond to environmental fluctuations, and how quickly nutrients contained in their tissues might be made available to other organisms. By addressing each of these questions, we could advance our basic knowledge of nutrient dynamics as well as help predict ecosystem responses to global change. Until recently, soil biologists have been hampered by difficulties inherent with working on microscopic organisms belowground. However, advances in molecular approaches now allow us to survey species in situ, and isotopic techniques applied in concert enable us to determine the function of fungal groups and to track the fate of nutrients on small scales. |
