We studied the relationships between assemblages of soil microfungi and plant communities in the southern boreal mixed-wood forests of Quebec. Sampling took place in 18,100 m2 plots from an existing research site. Plots were separated into three cate

Arbuscular mycorrhizal fungi (AMF) communities in Clintonia borealis roots from a boreal mixed forests in northwestern Quebec were investigated. Roots were sampled from 100 m2 plots whose overstory was dominated by either trembling aspen (Populus tre

The effects of light and tree size on the root architecture and mycorrhiza of yellow birch (Betula alleghaniensis Britton) and sugar maple (Acer saccharum Marsh) growing in the understory of deciduous forests in southern Quebec, Canada were studied.

Ectomycorrhizal (ECM) diversity was measured in 12 mixed-wood stands in the Abitibi region of north-western Quebec. Stands were of similar age and were situated on similar mineral soil deposits, but supported varying proportions of ECM host trees. Ho

The mycorrhizae of younger (2- to 3-year-old) and older (5- to 12-year-old) yellow birch (Betula alleghaniensis Britton) and sugar maple (Acer saccharum Marsh.) seedlings and saplings were recorded from naturally regenerating plants in gaps created b

During a survey of the vesicular–arbuscular mycorrhizal (VAM) associations of forest herbs in a deciduous forest in the southern Laurentian mountains in Quebec, two liliaceous species, Clintonia borealis and Medeola virginiana, revealed very distin

The numbers and types of spores of vesicular-arbuscular mycorrhizal fungi occurring in the top 15 cm of the soil in three maple forests in Eastern Canada were investigated using traditional wet-sieving/decanting methods. In the most acid site, at St.

Three antibiotic peptides, LP237-F8 (1), F5 (2), and F7 (3), were isolated from the liquid culture of the fungus Tolypocladium geodes. Chemical shift assignments of the 1H and 13C NMR resonances and sequencing of these metabolites were achieved by ex

The development, condition, and incidence of vesicular–arbuscular mycorrhizae of Acer saccharum (sugar maple) seedlings grown in the greenhouse in natural sugar maple forest soil substrate were examined. The effects of the addition of a cation mixt

The variations in the numbers of propagules and in the colonization rates of vesicular–arbuscular mycorrhizal fungi in soils of two sugar maple forests, one near Waterloo in southern Ontario, the other near Lacolle in southern Quebec, were investig
