Nutrient Allocation Strategies to Eggs by Lesser Snow Geese (Chen caerulescens) at a Sub-Arctic Colony
(University of California Press, 2011-01)
The relative allocation of endogenous- and exogenous-derived nutrients to reproductive investment in Arctic-nesting geese is aﬀected by body size, migration distance, and proximate conditions on the wintering, staging, and ...
Is the decline of soil microbial biomass in late winter coupled to changes in the physical state of cold soils?
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 ...
Soil Microbial and Nutrient Dynamics During Late Winter and Early Spring in Low Arctic Sedge Meadows
(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 ...
