A Common Seasonal Pattern Found in Bacterial Communities in Six Arctic Rivers
30.11.2009
New research on bacterial communities in six large Arctic riverecosystems (in the Ob, Yenisey, Lena, Kolyma, Yukon and MackenzieRivers) reveals predictable temporal patterns, suggesting scientistscould use them as markers for monitoring climate change in the PolarRegions. The Proceedings of the US National Academy of Sciences showedbacterial communities in the studied…
