"Rising Temperatures Boost Soil Bacteria Diversity"

A study from the University of Vienna reveals that warmer soils lead to a greater diversity of active microbes, challenging the previous assumption that higher temperatures accelerate microbial growth and carbon release. The research, conducted in a subarctic grassland in Iceland, found that while soil warming increased microbial growth at the community level, the growth rates of microbes in warmer soils were similar to those at normal temperatures. However, the pivotal difference lay in the bacterial diversity, with warmer soils harboring a more varied array of active microbial taxa. This finding has significant implications for understanding the soil microbiome's reaction to climate change and its impact on future carbon dynamics.
