Spatial relationship of landform surface features and biocrusts, and their effect on soil microbial biomass on an alluvial fan Open
The spatial cover of biocrusts represents a suitable habitat for the activity of soil microorganisms in semi‐arid and arid regions. Microorganisms are one of the essential components of soil quality. Therefore, it is necessary to understan…

The effects of biocrusts on soil parameters in a semi-arid pediment at north-eastern Iran Open
The biocrusts are organized by soil-surface communities of biota that live within or on the very top of soil surface and play an important role in soil conservation. They include lichens, mosses, fungi, cyanobacteria, eukaryotic algae, and…

Evaluating the impacts of combating-action programs on desertification hazard trends: A case study of Taybad-Bakharz region, northeastern Iran Open
In Iran, desertification is usually caused by both nature and humans̓ greedy behaviors such that, more than 75% of the country’s area is dominated by arid zones, and most of the ecosystems are being destroyed due to human activities current…
