  • Clearing of Cache & Cookies
    Clearing of Cache & Cookies What is cache? Cache memory is temporary memory used to store information that you accessed when visiting web sites. Cache speeds up a computer’s connection time with web sites that have been visited previously by locally storing information about that connection on the computer so that it does not have to be downloaded each time a site is visited. Why should cache be cleared periodically? Cache can become corrupt or outdated. As a result, cache can slow down or prevent a web page’s output and/or connection instead of assisting it. Clearing cache deletes corrupt or outdated data. It also removes unnecessary information stored in memory from sites that were only visited one time.

Green1, Faraz Rahman1, Matthew A. Saxton2,3, Kurt E. Williamson1,2,* 1Department of Biology, College of William & Mary, Williamsburg, Virginia 23185, USA 2Environmental Science and Policy Program, College of William & Mary, Williamsburg, Virginia 23185, USA 3Present address: Department of Marine Sciences, University of Georgia, Athens, Georgia 30602, USA ABSTRACT: Little is known about the composition and diversity of temperate freshwater viral communities. This study presents a metagenomic analysis of viral community composition, taxo- nomic and functional diversity of temperate, eutrophic Lake Matoaka in southeastern Virginia (USA). Three sampling sites were chosen to represent differences in anthropogenic impacts: the Crim Dell Creek mouth (impacted), the Pogonia Creek mouth (less impacted) and the main body of the lake (mixed). Sequences belonging to tailed bacteriophages were the most abundant at all 3 sites, with Podoviridae predominating. The main lake body harbored the highest virus genotype richness and included cyanophage and eukaryotic algal virus sequences not found at the other 2 sites, while the impacted Crim Dell Creek mouth showed the lowest richness. Cross-contig com- parisons indicated that similar virus genotypes were found at all 3 sites, but at different rank- abundances. Hierarchical cluster analysis of multiple viral metagenomes indicated high genetic similarity between viral communities of related environments, with freshwater, marine, hypersaline, and eukaryote-associated environments forming into clear groups despite large geographic dis- tances between sampling locations within each environment type.
