Randomized trial examines the roles of calcium and microbial communities in organic carbon stabilization in evaporative lakes, suggesting important ecological implications.
Key Points
This research aims to explore how calcium and microbial communities regulate organic carbon stabilization in evaporative lake sediments.
Collected sediment samples from ten inland evaporative lakes on the Inner Mongolian Plateau.
Conducted systematic analysis of geochemical variables and microbial 16S rRNA gene amplicon sequencing.
Examined the correlation between various organic carbon components and calcium concentrations.
OC concentrations varied from 0.20 to 6.16 mg/g, with calcium concentrations from 1.30 to 32.24 mg/g.
Mineral associated organic carbon positively correlates with calcium (R² = 0.83, p < 0.001).
Bacterial diversity shows a positive correlation with particulate organic carbon (r = 0.42, p < 0.05).
