Increases in the abundance of woody species have been reported to affect provisioning ecosystem services drylands worldwide. However, it is virtually unknown how multiple biotic and abiotic drivers, such as climate, grazing, fire, interact determine dominance across global drylands. We conducted a standardized field survey 304 plots 25 countries assess climatic features, soil properties, fire dryland rangelands. Precipitation, temperature, grazing were key determinants tree shrub dominance....
Various factors influence biocrust effects on infiltration and soil moisture. On China's Loess Plateau, well‐developed moss‐dominated biocrusts reduce suppress shrub growth, however, the interrelationships between rainfall conditions disturbance management to alleviate these impacts are unknown. In a semiarid watershed we applied two forms of disturbance, scarification (controlled harrowing) compaction (simulated grazing), at four intensity levels (control‐intact, light, moderate, heavy)...
As an important soil cover in deserts, biological crusts play a central role ecosystem function such as nutrient cycling, nitrogen fixation, and carbon sequestration. Many crust organisms could fix CO2 through photosynthesis to improve organic content. There is knowledge gap the origin of (SOC) from on regional level, which restricts prediction pool. Based 45 plots Mu Us sandy land (42200 km2), we measured SOC content density (SOCD) two types typical (moss crusts, algal crusts) their...
Biological crusts (Biocrusts) are important surface active coverings in arid and semi-arid regions, which affect the content of soil organic carbon (SOC), SOC labile fractions stability through photosynthetic fixation. At present, studies on variation characteristics SOC, biocrusts rather limited. In this study, two types typical (moss algae crusts) were selected along a precipitation gradient from northwest to southeast Mu Us Sandland (straight line distance 188 km) by measuring microbial...
<p>Biocrusts (Biological soil crusts) are a living ground cover widely distributed in arid and semi-arid regions worldwide provide important ecological functions ecosystems. As an part of biocrusts, the microorganisms formation succession biocrusts should not be underestimated. However, microbial processes among different types poorly understood. We used high-throughput sequencing to identify bacteria fungal community two lichen crust moss crust, Mu Us Sandland. The aims were...
