Core Insights - The research highlights the diverse and protective biocrust microbiome associated with the Great Wall of China, emphasizing its significance for the preservation of this historical monument [3][7]. Group 1: Research Findings - The study investigated six sampling points along a 600 km section of the Great Wall, revealing a patchy landscape of biocrust and bare wall, which may harbor unique microbial communities [4][6]. - Compared to bare wall areas, the abundance, diversity, and co-occurrence network complexity of bacteria and fungi in biocrust-covered regions increased significantly by 12%-62% [6]. - Metagenomic analysis indicated that biocrust enhanced the overall functional gene abundance and stress resistance metabolic pathways by 4%-15%, while significantly reducing pathways related to biological corrosion [6]. Group 2: Environmental Factors - Drought severity was identified as a key environmental factor shaping the microbial community associated with the Great Wall [6]. Group 3: Implications for Preservation - The findings provide a scientific basis for the protection of the Great Wall, contributing to efforts to preserve this unique human heritage for future generations [7][8].
