Seasonal patterns of viral, microbial and planktonic communities in Sidi Salem: a freshwater reservoir (North of Tunisia)
* We examined abundances of selected microorganisms and seasonal distribution patterns of viral, microbial and planktonic communities in Sidi Salem reservoir.
* Picocyanobacteria abundances were higher in the euphotic strate and decrease with depth.
* The vertical distributions of heterotrophic bacteria showed important fluctuations during the period of study. This community was characterized by a clear separation between High DNA and Low DNA content populations.
* The VLP community was highly dynamic during the period of monitoring.
