Our world is changing, and warming temperatures will alter our natural ecosystems. Some of these changes will be straightforward, like animal ranges creeping northward as they strive to maintain their ideal temperatures. But other changes will be more complicated, as warming sets off complex chain reactions that reverberate through these systems.
"Our study is exciting because scientists haven't extensively explored how changes in the plant and decomposer communities will interact under climate warming," says Emma Dawson-Glass, Research Specialist in the Stuble Community Ecology lab and lead author on the study."Studying how decomposition is impacted by warming can help us better understand how the function of our environment is being altered by climate change.
They found that soil microbial and plant communities interacted in important ways. As expected, decomposition decreased when there was more of a slower-decomposing grass —but only when certain microbes were in the soil. When the soil microbes had been exposed to warming, more Indian grass didn't slow decomposition.
