Description
Isabel Mas Martinez and six co-authors wrote a 2024 study on what shapes the living crusts on High Arctic soils. Biological soil crusts fix nitrogen, produce carbon, and hold fragile tundra soil together. Their inner communities, though, are poorly mapped. The team sampled along an elevation gradient from 101 to 314 meters.
DNA sequencing revealed the crust communities in depth. Temperature, soil acidity, and nutrient levels significantly steered composition. Elevation itself, surprisingly, had no direct effect once those factors were counted. Green algae relatives and fungi dominated the eukaryotes, while two bacterial phyla led the prokaryotes. Cyanobacteria, the crust's solar panels, were the most abundant light harvesters. The work links microclimate and soil chemistry to tundra function. As the Arctic warms, such baselines matter.
