Resolving ecosystem scale interactions using large-scale stable isotope labeling and other novel techniques

Session ID#: 82502

Session Description:
As anthropogenic perturbations increase, ecosystems respond and adapt in complex and often unpredictable ways. Responses of individual species to perturbations, as well as interactions among limited taxa can be studied closely under controlled conditions in a laboratory. Attempts to upscale these results to an ecosystem scale through models often fall short, as unforeseen feedbacks play out in nature. Manipulations on the scale of experimental ecosystems when combined with stable isotope labeling or other novel techniques can provide a critical link to elucidate interlinked responses to controlled disturbances. This session invites contributions from studies that investigate ecosystem responses from the molecular and microbial to atmospheric scale, using novel techniques such as large-scale stable isotope labeling, including at the position-specific level. We welcome studies from large-infrastructure experimental ecosystems, as well as natural ecosystems.
