Table_1_Local Habitat Filtering Shapes Microbial Community Structure in Four Closely Spaced Lakes in the High Arctic.DOCX
Arctic lakes are experiencing increasingly shorter periods of ice cover due to accelerated warming at northern high latitudes. Given the control of ice cover thickness and duration over many limnological processes, these changes will have pervasive effects. However, due to their remote and extreme l...

Arctic lakes are experiencing increasingly shorter periods of ice cover due to accelerated warming at northern high latitudes.

The aim of this study was to characterize and compare the microbial communities of four closely spaced lakes in Stuckberry Valley (northern Ellesmere Island, Canadian Arctic Archipelago), in the coastal margin zone of the Last Ice Area, that differed in their physicochemical, morphological and catchment characteristics.
