Temporal dynamics and structure of picocyanobacteria and cyanomyoviruses in two large and deep peri-alpine lakes

We conducted a 1-year survey of the surface waters of two deep peri-alpine lakes, and investigated the abundances and community structure of picocyanobacteria and co-occurring cyanomyophages. Picocyanobacterial abundances ranged between 4.5 × 104 and …

Prevalence of Viral Photosynthetic and Capsid Protein Genes from Cyanophages in Two Large and Deep Perialpine Lakes

Cyanophages are important components of aquatic ecosystems, but their genetic diversity has been little investigated in freshwaters. A yearlong survey was conducted in surface waters of the two largest natural perialpine lakes in France (Lake Annecy …

Dynamics of various viral groups infecting autotrophic plankton in Lake Geneva

Viral community structure and dynamics were investigated for the first time in surface waters (0–20 m) of Lake Geneva over a 5-month period between July and November 2011. Abundances of autotrophic picoplankton, heterotrophic bacteria and virus-like …
