Transformation indicates when the variable BSP has been root transformed (TR) to fit ANOVA homogeneity of variance and normality assumptions, or, when non-parametric Kruskal–Wallis and multiple comparison of mean ranks (MR) were applied. All differences described as (post hoc results) were significant at p < 0.05 (post hoc parametric Tukey-except f).

^∗The response for seven sampled stations was tested independently as follows: (a) Ho source (H0); (b) H3 source (H3); (c) H3 stream running water (H3-RW); (d) H4 connected pond (H4-CP); (e) H4 isolated pond (H4-IP); (f) H3 isolated pond (H3-IP); (g) H4 isolated pond “Virgin Mary pond” (H4-VMP).

^∗∗Total bacterial secondary production (BSP) and average bacterial production per cell (BSP cell^-1) incubated under different solar radiation treatments: full sun (PAB treatment), no UVB (PA treatment), no UV, only PAR (P treatment), and no light exposure (dark treatment).
