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 ...
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, ...
Free amino acids in Arctic salt-marsh coastal sites and plant nitrogen acquisition
(Ottawa : National Library of Canada = Bibliothèque nationale du Canada, 2004)
The importance of free amino acids as a source of plant nitrogen was examined in an Arctic coastal salt-marsh. Concentrations of inorganic nitrogen in salt-marsh soils were low relative to those reported for most temperate ...
Seasonal partitioning of resource use and constraints on the growth of soil microbes and a forage grass in a grazed Arctic salt-marsh
(Springer Verlag, 2009)
Seasonal growth responses of plants and soil microorganisms to additions of nitrogen (N), phosphorus (P) and carbon (C) were examined in goose-grazed and exclosed plots in an Arctic salt marsh. Plants showed strong growth ...
