WebIntroduction. Biological soil crusts (BSCs) play pivotal roles in the stability of dryland ecosystems (Belnap and Lange, 2003; Belnap, 2006) and significantly contribute to the global cycling of nitrogen (Elbert et al., 2012).Compositionally, BSCs are polyextremotolerant microbial topsoil communities (Figures 1A,B), comprised of bacteria, archaea, fungi, … WebMar 15, 2024 · The cryptobiotic crust is also a defender against erosion. Because the sticky webs of soil retain water, plant life is able to root into the spongy crust which enables …
