Bacterial secondary production (BSP) experimental response to solar radiation at seven stations in Salar de Huasco. Error bars represent standard deviation. The BSP samples from each sampling site were incubated under four different solar conditions: Full sun (PAB treatment), no UVB (PA treatment), no UV (PAR treatment), and no light exposure (dark treatment). (A) Average BSP under solar radiation treatments expressed as μg C l-1 h-1. (B) Variation of BSP as percentage of dark treatment (C). BSP cell-1 (as proxy of growth efficiency) expressed as fg C cell-1 h-1. (D) Group average cluster of station similarity based on BSP response to different solar radiation treatments.
