Vegetation mosaics, patch dynamics and alternate stable states in an arctic intertidal marsh.
(Ottawa : National Library of Canada = Bibliothèque nationale du Canada, 2002)
Soil degradation occurs following loss of vegetative cover at both the landscape and individual patch scale at La Pérouse Bay, Manitoba. At the landscape scale, soils from vegetated patches had a higher infiltration rate, ...

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 ...
Revegetation trials in degraded coastal marshes of the Hudson Bay Lowlands.
(Ottawa : National Library of Canada = Bibliothèque nationale du Canada, 1998)
Intense foraging by an increasing population of lesser snow geese, Anser caerulescens L., has led to the conversion of former salt-marsh swards, dominated by Puccinellia phryganodes and Carex subspothacea to hypersaline ...
The allocation of inorganic nitrogen (15 NH4+) to soil, microbial and plant biomass in an Arctic salt marsh.
(Ottawa : National Library of Canada = Bibliothèque nationale du Canada, 2004)
This study has demonstrated, through the shared distribution of a single resource (15 NH4+), that plants and soil microbes compete for inorganic N in a N-limited system. At La Pérouse Bay, soil microorganisms out-compete ...
