Temporal dynamics and decay of putatively allochthonous and autochthonous viral genotypes in contrasting freshwater lakesIan Hewson
Department of Microbiology, Cornell University, Ithaca, New York, USA
Appl Environ Microbiol 78:6583-91. 2012..Our data indicate that putatively allochthonous viruses are present in lake plankton and sediments, where their temporal dynamics reflect active transport to the lake during hydrological events and then decay once there...- Spatial patterns and light-driven variation of microbial population gene expression in surface waters of the oligotrophic open oceanIan Hewson
