Long term drivers of aboveground-belowground linkages and ecosystem functioning.
Prof. David Wardle is visiting our department and will hold a guest seminar in EECRG's weekly seminar series. Join in person in Tunet, or online (contact Dagmar Egelkraut for link).
Summary: All terrestrial ecosystems consist of communities of aboveground and belowground organisms, which interact with each other over short time scales, but which both drive and respond to processes that operate over much longer time scales. Here I illustrate the linkage between short-term interactions between aboveground and belowground biota, and long term ecological processes, using examples from our work across natural environmental gradients of fire history on lake islands in northern Sweden, ecosystem development and decline across long term chronosequences, and elevational gradients in mountain environments. In combination, these examples highlight that understanding aboveground-belowground linkages offer many insights about the abiotic and biotic drivers of ecosystems, including those that operate over much longer time scales that the linkages themselves operate such as climate and geology, as well as those that are relevant to understanding the ecosystem impacts of human-driven global change.
