Significant statistical differences between the number of fungi and fungus-like organisms identified in the oxbow lakes and tributaries of the Narew in spring

Statistically significant correlations between the number of fungi and fungus-like organisms identified in spring in the studied waters and the values of hydrochemical parameters: A1 – temperature, B1 – pH, C1 – carbon dioxide, D1 – magnesium, E1 – sulphates, F1 – chlorides

Statistically significant correlations between the number of fungi and fungus-like organisms identified in autumn in the studied waters and the values of hydrochemical parameters: A2 – pH, B2 – ammoniacal nitrogen, C2 – nitrate nitrogen, D2 – phosphates, E2 -suspended solids, F2 – calcium ions, G2 – magnesium, H2 – iron, I2 – dissolved solids
