^aA combination of environmental parameters, including TDS, temperature, pH, DO, prokaryotic abundance, and sampling depth, if any.

^br reflects the correlation level between the two matrices.

^cA P value of less than 0.05 represents statistical significance of the correlation (shown in boldface).
