Nutrient Limitation of Plants and Soil Microbial Growth in an Arctic Coastal Salt Marsh.
(Ottawa : National Library of Canada = Bibliothèque nationale du Canada, 2005)
In order to assess the nutrient limitation of plants and soil microorganisms in the Arctic coastal salt marsh at La Pérouse Bay, Manitoba, a nitrogen (N) and phosphorus (P) fertilization experiment was conducted. The ...
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 ...

Soluble carbohydrate content of shoots of Arctic wetland plants that are consumed by lesser snow geese
(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 ...
Patterns and Processes of Species Diversity in Fragmented Northern Hardwood Forests.
(Toronto : University of Toronto, 2001)
Twenty-four upland hardwood forests were examined to determine the influence of plant dispersal and environmental heterogeneity on the composition and richness of species in the forest understory. Patterns in the dispersal ...
Goose-induced Changes in Vegetation and Land Cover between 1976 and 1997 in an Arctic Coastal Marsh
(Institute of Arctic and Alpine Research (INSTAAR), University of Colorado, 2005)
Since the 1970s, a breeding colony of lesser snow geese (Chen caerulescens caerulescens L.) at La Pérouse Bay, Manitoba, has grown 8% annually. This increase has led to significant loss of plant cover in all major salt- ...
