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 ...
