Ectomycorrhizal fungal succession in jack pine stands following wildfire

- 1 March 1995
There was a significant increase in mycorrhizal species richness between the 6 and 41-yr-old stands and this was primarily the result of partial replacement of Suillus brevipes on the 6-yr -old trees by late-stage fungi in the older stands.
Microbial biomass, nitrogen and phosphorus mineralization, and mesofauna in boreal conifer and deciduous forest floors following partial and clear-cut harvesting
The effects of partial and clear-cut harvesting on forest floor physical, chemical, and biological properties, forest floor mesofauna, and nutrient cycling were investigated in conifer- and deciduo...
Host response to inoculation and behaviour of introduced and indigenous ectomycorrhizal fungi of jack pine grown on oil-sands tailings
Pinusbanksiana Lamb, seedlings were inoculated with nine mycorrhizal fungi and outplanted on an oil-sands containment dyke that had been amended with muskeg peat, with results that appeared to be a noncompetitive replacement process.
Forest floor microarthropod abundance and oribatid mite (Acari: Oribatida) composition following partial and clear-cut harvesting in the mixedwood boreal forest
The effects of partial and clear-cut harvesting on abundance and community composition of forest floor microarthropods and oribatid mites were investigated in conifer and deciduous stands of the mi...
Ectomycorrhizas of regenerating stands of lodgepole pine (Pinus contorta)
The ectomycorrhizal community associated with regenerating lodgepole pine (Pinus contorta Loud.) after clear-cutting in southwestern Alberta was investigated in 6-, 10-, and 19-year-old cut blocks…
EFFECTS OF SURFACE MINING ON THE MICROBIOLOGY OF A PRAIRIE SITE IN ALBERTA, CANADA
Soil respiration, microbial biomass C, ATP, actinomycete numbers, hyphal lengths and N2-fixing potential were significantly lower in the mined soil particularly when compared to the undisturbed topsoil, while mining caused the fungal community to shift from one dominated by Chrysosporium-Pseudogymnoascus and sterile dark organisms to onedominated by Alternaria spp.
Soil biological criteria as indicators of soil quality: Soil microorganisms
Diverse soil microbiological studies have attempted to assess deterioration or improvement in soil quality. These studies have been done on three levels: population level studies of the dynamics of…

An appraisal of soil fungal biodiversity: the crossroads between taxonomic and functional biodiversity
The aim of this paper is to expand upon current discussions on fungal biodiversity by introducing aspects of the biology of fungi that may influence patterns of biodiversity and to present the discussion of the biodiversity of soil fungi in an ecological framework from which comparisons with other taxonomic groups can be made.
