Abstract
Abstract Sand burial of crusts, caused by ant burrowing, is a common phenomenon in desert landscapes, yet the potential impacts on soil processes are unknown. Three sand burial depths, 3.0–5.0 mm (deep burial), 1.0–1.5 mm (shallow burial), and 0 mm (control) affecting two dominant biocrusts (viz., cyanobacteria‐lichen crusts and moss crusts) sampled in the moist and dry seasons were selected to explore this issue in two vegetation areas of the Tennger Desert. We collected 180 samples from biocrust layers and topsoil to assess soil physicochemical properties, microbial biomass, basal respiration, and enzymes activities. The results showed that sand burial of crusts reduced soil microbial biomass, basal respiration, and enzyme activities, while deep burial caused a substantial decline in these parameters. Sand burial interfered with the biocrusts structure (e.g., rupture and flaking) and properties, subsequently causing soil‐nutrient deprivation and soil microclimate deterioration. These are major mechanisms for decreasing soil microbial biomass, basal respiration, and enzyme activities. Moss crusts had significantly higher levels of the microbial parameters than cyanobacteria‐lichen crusts following sand burial, indicating that biocrusts' tolerance to sand burial was synchronized with their progressive succession. In addition, soil microbial parameters were higher in natural vegetation areas than artificial vegetation areas following sand burial. Such observations suggest that high soil fertility could mitigate the negative effects of sand burial on soil processes. In conclusion, sand burial induces biocrust degradation and further disturbs surface soil processes in arid desert ecosystems.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
