Viriobenthos in aquatic sediments: variability in abundance and production and impact on the C-cycle
Abstract In the last 15 years viruses have been acknowledged as important components of the benthic microbial community, but our understanding of their role in the functioning of aquatic systems remains poor. Viruses can affect bacterial assemblages and mineralization activities, but the extent of t...

| 520 | |a Abstract In the last 15 years viruses have been acknowledged as important components of the benthic microbial community, but our understanding of their role in the functioning of aquatic systems remains poor. Viruses can affect bacterial assemblages and mineralization activities, but the extent of their influence remains unclear. We synthesised available data on viriobenthos dynamics to understand which factors drive the variability in their abundance and production and to quantify their influence on the benthic carbon cycle. Results highlighted a large variability in viral abundance (from 2 × $ 10^{8} $ to 7 × $ 10^{9} $ virus $ ml^{−1} $) and production estimates (from 1 × $ 10^{7} $ to 5 × $ 10^{8} $ virus $ ml^{−1} $ $ h^{−1} $) obtained with different techniques. This variability limits the comparability of data across studies and indicates the need to improve protocols and develop standard methods. The dynamics of viruses infecting prokaryotes appeared linked to prokaryotic metabolism, supporting the hypothesis that benthic viruses originate directly in the sediment as a result of infection events rather than sinking from the water column. Sediment characteristics (porosity, temperature, depth) appeared to effect viral production, mostly indirectly by influencing bacterial productivity and abundance, but possibly also interfering with the rate of virus–host encounter. Conversely, trophic status appeared unrelated to viral parameters. Viral contribution to carbon turnover appeared low and unrelated to temperature, water depth, trophic status and salinity. More detailed studies are needed to understand the pelagic contribution to the viriobenthos and the extent to which dissolved organic carbon released by viruses is effectively used by bacteria. | ||

We synthesised available data on viriobenthos dynamics to understand which factors drive the variability in their abundance and production and to quantify their influence on the benthic carbon cycle. Results highlighted a large variability in viral abundance (from 2 × $ 10^{8} $ to 7 × $ 10^{9} $ virus $ ml^{−1} $) and production estimates (from 1 × $ 10^{7} $ to 5 × $ 10^{8} $ virus $ ml^{−1} $ $ h^{−1} $) obtained with different techniques.

Viriobenthos in aquatic sediments: variability in abundance and production and impact on the C-cycle |
| abstract |
Abstract In the last 15 years viruses have been acknowledged as important components of the benthic microbial community, but our understanding of their role in the functioning of aquatic systems remains poor. Viruses can affect bacterial assemblages and mineralization activities, but the extent of their influence remains unclear. We synthesised available data on viriobenthos dynamics to understand which factors drive the variability in their abundance and production and to quantify their influence on the benthic carbon cycle. Results highlighted a large variability in viral abundance (from 2 × $ 10^{8} $ to 7 × $ 10^{9} $ virus $ ml^{−1} $) and production estimates (from 1 × $ 10^{7} $ to 5 × $ 10^{8} $ virus $ ml^{−1} $ $ h^{−1} $) obtained with different techniques. This variability limits the comparability of data across studies and indicates the need to improve protocols and develop standard methods. The dynamics of viruses infecting prokaryotes appeared linked to prokaryotic metabolism, supporting the hypothesis that benthic viruses originate directly in the sediment as a result of infection events rather than sinking from the water column. Sediment characteristics (porosity, temperature, depth) appeared to effect viral production, mostly indirectly by influencing bacterial productivity and abundance, but possibly also interfering with the rate of virus–host encounter. Conversely, trophic status appeared unrelated to viral parameters. Viral contribution to carbon turnover appeared low and unrelated to temperature, water depth, trophic status and salinity. More detailed studies are needed to understand the pelagic contribution to the viriobenthos and the extent to which dissolved organic carbon released by viruses is effectively used by bacteria. © Springer Basel 2013 |
