Microbe-stuffed soil crusts menaced by climate change

Using a novel method to detect microbial activity in biological soil crusts, or biocrusts, after they are wetted, a Penn State–led research team in a new study uncovered clues that will lead to a better understanding of the role microbes play in forming a living skin over many semi-arid ecosystems around the world. The tiny organisms—and the microbiomes they create—are threatened by climate change.
