Article Synopsis
- Hamilton Harbour, a troubled part of Lake Ontario, faces ongoing algal blooms despite efforts to improve water quality, prompting research on its bacterial communities.
- Researchers collected and analyzed water samples biweekly during summer and fall, finding varying dominance of Actinobacteria and Cyanobacteria across seasons, indicating a complex biodiversity.
- Functional gene analyses showed seasonal shifts in metabolic processes like photosynthesis and nitrogen fixation, providing insights that could help guide remediation strategies in the harbour.
Inspired by recent discoveries of the prevalence of large viruses in the environment, we reassessed the longstanding approach of filtering water through small-pore-size filters to separate viruses from cells before metagenomic analysis. We collected samples from three sites in Hamilton Harbour, an embayment of Lake Ontario, and studied 6 data sets derived from <0.45-μm- and >0.

- Aquatic viruses, particularly in freshwater environments, have not been thoroughly characterized, prompting a study to analyze virus communities in a freshwater harbor across different seasons and locations.
- Community DNA was extracted and sequenced, revealing the presence of various virus groups, mainly virophages, which showed stability in their abundance despite changes in other virus types like Mimiviridae.
- The study found that chlorophyll a was the only environmental factor significantly explaining variations in virus community composition, highlighting the ecological significance and diversity of freshwater virus assemblages.
