Is the decline of soil microbial biomass in late winter coupled to changes in the physical state of cold soils? 

Jefferies, Robert L.; Walker, Alan; Edwards, Kate A.; Dainty, Jack (Elsevier, 2010)
During winter when the active layer of Arctic and alpine soils is below 0 °C, soil microbes are alive but metabolizing slowly, presumably in contact with unfrozen water. This unfrozen water is at the same negative chemical ...

Soluble carbohydrate content of shoots of Arctic wetland plants that are consumed by lesser snow geese 

Jefferies, Robert L.; Edwards, Kate A. (NRC Research Press, 2008)
We recorded seasonal changes in the total amounts of soluble carbohydrates in shoots of salt- and fresh-water coastal plants at La Pérouse Bay, northern Manitoba, to determine whether adult snow geese and their goslings ...

Soil Microbial and Nutrient Dynamics During Late Winter and Early Spring in Low Arctic Sedge Meadows 

Edwards, Kate A. (Toronto : University of Toronto, 2010)
Microbial activity occurs year-round in Arctic soils, including during the winter when soils are frozen. From 2004 to 2008 I monitored soil microbial and nutrient dynamics in low Arctic wet and dry sedge meadows near ...

Soil microbial and nutrient dynamics in a wet Arctic sedge meadow in late winter and early spring 

Edwards, Kate A.; McCulloch, Jennifer; Kershaw, Peter G.; Jefferies, Robert L. (Elsevier, 2006)
Microbial activity is known to continue during the winter months in cold alpine and Arctic soils often resulting in high microbial biomass. Complex soil nutrient dynamics characterize the transition when soil temperatures ...
