Widespread decline of whitebark and limber pines in the northern Rocky Mountains (USA) has created an imperative to understand functional diversity in their ectomycorrhizal associates. Because suilloid fungi are likely important in successful reestab

Increased use of anthropogenically fixed N and the release of N in combustion products have led to concerns about possible long-term impacts on terrestrial ecosystems. Previous studies demonstrating the potential of atmospheric N deposition to influe

This study examined select, naturally-occurring tree mycorrhizae for differences related to efficiency of organic phosphorus hydrolysis in forest soils. We investigated the activity of several phosphatases and root respiration in field-collected ecto

Because plant litter decomposition is directly mediated by extracellular enzymes (ectoenzymes), analyses of the dynamics of their activity may clarify the mechanisms that link decomposition rates to substrate quality and nutrient availability. We inv

Recently, ergosterol analysis has been used to quantify viable fungal biomass in resynthesized ectomycorrhizae. An objective of our study was to quantify ergosterol in a range of ectomycorrhizal isolates under differing growth conditions. In addition

The forest floor of a New England red pine plantation was limed to determine whether this would influence the numbers or types of ectomycorrhizas associated with this host. The potential effect of lime on the mineralization of soil organic phosphorus

To better understand the physiological importance of acid phosphatase activity we examined the effects of inorganic and organic phosphorus growth sources on enzyme activity and 32P uptake in several ectomycorrhizal fungi. Mycelium of eight isolates f

The microbial degradation of plant litter is mediated by extracellular enzymes. Their specificity makes enzyme assays useful for comparing microbial communities, monitoring community succession, evaluating the effects of disturbance or ecosystem vari
