Abstract

This paper considers the contribution of micro-geomorphology to biodiversity in the extreme arid desert systems. The AA. tested the hypothesis that micro-geomorphological features determine the spatial distribution of biological soil crusts (BSCs) by reallocating related abiotic resources at small- and medium-scales in the Tengger Desert. Their results showed that higher soil pH and higher total potassium content in topsoil positively correlated with the colonization of cyanobacteria and algae in the earliest successional stages of BSCs, while increasing dust deposition onto the topsoil enhanced the development of lichen and mosses in the later stages of BSCs
