Biocrust outdoor testing plots

Detailed Description

USGS scientists created outdoor testing plots where large squares of biocrusts were exposed to different warming and precipitation factors over time. Researchers not only looked at how the biocrusts responded, but also measured the amount of energy that the different biocrust communities reflected back into the atmosphere relative to how much energy came in from the sun.

Arid and semiarid ecosystems are expected to experience significant changes in temperature and precipitation patterns, which may affect soil organisms in ways that cause surfaces to become lighter in color and thus reflect more sunlight, according to a new USGS study.
