Plant-Soil-Microbe Inte ractions in a Changing World
Interactions between plants and m icrobes in the rhizosphere are regulating nutrient cycling, plant pro ductivity, and ecosystem resilience. Rapidly occurring climate and la nd-use change are reshaping these interactions in complex and often u npredictable ways and can affect short- and longer term ecosystem fun ctioning. Rhizosphere dynamics are particular undesrstudied in tropic al ecosystems, which are often growing on highly weathered mineral so ils, and the collaboration and competition between microbes and plant s is highly important for forest nutrient cycling. I aim to unravel s oil edaphic controls over microbial structure and functions across tr opical forest soil systems across larger forest stand to small scale rhizosphere scales and will discuss how root dynamics and exudate com position can influence microbial nutrient cycling.
