Warmer soils harbor a greater diversity of active microbes, according to a new study from researchers at the Centre for Microbiology and Environmental Systems Science at the University of Vienna. The study, published in, represents a significant shift in our understanding of how microbial activity in the soil influences the global carbon cycle and possible feedback mechanisms on the climate.
“We saw that more than 50 years of consistent soil warming increased microbial growth at the community level,” says Dennis Metze, PhD student and primary author of the study. “But remarkably, the growth rates of microbes in warmer soils were indistinguishable to those at normal temperatures.” The pivotal difference lay in the bacterial diversity: Warmer soils harbored a more varied array of active microbial taxa.
