Nitrification potentials and landscape, soil and vegetation characteristics in two Central Appalachian watersheds differing in NO3− export
Two watersheds within 1 km of each other in the Central Appalachian mountains of West Virginia have similar management histories and receive 13 kg of N in atmospheric deposition, but NO3 � export… Expand
Diversity of Cenococcum geophilum isolates from serpentine and non-serpentine soils
Abstract Serpentine soils are characterized by a disproportionate level of Mg in relation to Ca and often contain phytotoxic levels of available Ni. Both of these factors may represent stresses to… Expand
The role of arbuscular mycorrhizas in decreasing aluminium phytotoxicity in acidic soils: a review

Soil acidity is an impediment to agricultural production on a significant portion of arable land worldwide. Low productivity of these soils is mainly due to nutrient limitation and the presence of… Expand
Aluminum-mycorrhizal interactions in the physiology of pitch pine seedlings
Aluminum (Al) in the rhizosphere adversely affects plant nutrition and growth. Although many conifer species, and pitch pine (Pinus rigida) in particular, have evolved on acidic soils where soluble… Expand
Stress responses in plants: Adaptation and acclimation mechanisms.
Partial table of contents: Carbon Balance of Stressed Plants: A Conceptual Model for Integrating Research Results (J. Amthor & K. McCree). Transport/Harvest Index: Photosynthate Partitioning in… Expand
Acid mist and soil Ca and Al alter the mineral nutrition and physiology of red spruce.
We examined the effects and potential interactions of acid mist and soil solution Ca and Al treatments on foliar cation concentrations, membrane-associated Ca (mCa), ion leaching, growth, carbon… Expand
Effects of serpentine soil factors on Virginia pine (Pinus virginiana) seedlings.
Effects of simulated serpentine soil conditions (elevated Mg:Ca ratio and Ni concentration) on seedlings from populations of Virginia pine (Pinus virginiana Mill.) from serpentine and non-serpentine… Expand
Nitrogen source effects on Al toxicity in nonmycorrhizal and mycorrhizal pitch pine (Pinus rigida) seedlings. I. Growth and nutrition
Previous studies indicated that the association of Pisolithus tinctorius with pitch pine (Pinus rigida) seedling roots prevented Al toxicity from developing when seedlings were exposed to 200 μM Al… Expand
Rhizosphere carbon deposition, oxidative stress and nutritional changes in two poplar species exposed to aluminum.
Species and hybrids in the genus Populus have become the focus of investigation for use in biofuels production and their capacity to sequester carbon (C) in the environment. The identification of… Expand
Utilization of AlPO4 as a phosphorus source by ectomycorrhizal Pinus rigida Mill. seedlings.
SUMMARY Mycorrhizal infection of roots of Pinus rigida Mill, seedlings by Pisolithus tinctorius Coker & Couch maintained normal foliar P relations when seedlings were exposed to Al in solution. To… Expand
