Within the framework of sustainable agriculture, integrated rice-snail-crayfish farming system has been recognized as a highly efficient agroecological approach that enhances crop production while minimizing application chemical fertilizers and pesticides.

Microbial succession on urban masonry surfaces is a critical yet understudied aspect of environmental microbiology, with implications for public health within the One Health framework. This study investigated how building age, orientation, and vegetative cover influence microbial diversity masonry, metal, glass substrates at University La Verne, California. Biophysical characterizations were conducted, communities analyzed using morphospecies richness DNA sequencing. Significant variation in species (χ2 = 20.3882, p 0.0011) (Fisher’s LSD, < 0.05) was observed. Masonry exhibited highest diversity, mean 23 compared to 14 metal 12 glass. Penicillium fungi dominated sites, comprising 45% colonies, while Pseudomonas Klebsiella more prevalent (35% 28%, respectively). did not follow linear progression but showed non-sequential shifts influenced by local conditions. The abundance Penicillium, known antibiotic production, raises concerns about spreading resistance genes. Opportunistic pathogens further highlight potential risks. These findings underscore importance understanding primary successional processes environments manage mitigate

The mining industry in China plays a pivotal role economic development but also leads to severe environmental issues, particularly heavy metal pollution soils. Heavy significantly impacts soil microbial communities due its persistence and long-term residual effects. We assessed changes diversity, community structure, assembly mechanisms selenium-impacted This study investigates the of selenium (Se) other metals on selenium-rich areas using full-length 16S rRNA gene sequencing. Our results showed that Se contamination altered composition, favoring metal-tolerant phyla such as Proteobacteria, Actinobacteriota Firmicutes, while reducing abundance sensitive groups like Acidobacteriota Chloroflexi. Microbial diversity decreased concentrations increased. Mantel test analysis revealed total potassium (TK), organic carbon, nitrogen, several metals, including zinc, niobium, titanium (Ti), manganese, rubidium, barium, potassium, cobalt, gallium (Ga), Se, chromium (Cr), vanadium, copper were positively correlated with composition across all samples. Random forest TK multiple elements [Cr, Ti, nickel (Ni), Ga Se] most important predictors bacterial emphasizing shaping communities. Co-occurrence network reduced complexity stability, high Se-contaminated soils exhibiting fragmented networks. Community was primarily driven by drift control soils, whereas dispersal limitation became more prominent toxicity. These findings highlight ecological consequences offer valuable insights for effective management remediation strategies.
