Mosses Play Key Roles in Ecosystems from Tropics to Tundra

by Carolyn Wilke 29 June 202329 June 2023

A global survey of mosses growing on soil found that the somewhat underappreciated plants cover a vast area and perform tasks such as sequestering carbon.

Biological Crusts Affected by Drought Can Still Stabilize Soils

by Terri Cook 17 March 202225 May 2022

Results of in situ experiments on natural microbial communities suggest that biological crusts can protect soils from erosion, but their protective role could be compromised under predicted future climate scenarios.
