Reactive polyphenols and dissolved nutrients in a nitrogen-limited headwater catchment, western Cascades, Oregon, USA

Creator:

Rasmussen, Janet K.

Abstract:

In undisturbed N-limited forested catchments, DON may represent over 90% of the total N lost in streams. Some ecologists have suggested that plant-derived reactive polyphenols may be responsible for DON binding and transport because polyphenol-protein complexes are known to precipitate out of solution, bind to mineral surfaces or organic matter...

In search of ecological advantages : Mycorrhizal facilitation of big huckleberry Vaccinium membranaceum (Doug.)

Creator:

Stocking, Peter

Abstract:

Temperate evergreen forests of the Pacific Northwest support big huckleberries (Vaccinium membranaceum) despite their nutrient impoverished soils. Acquisition of nitrogen and phosphorous are the major nutrients limiting V. membranaceum. The plant’s access to these resources is linked to their mycorrhizal symbiosis. To learn more about the symbionts of eriaceous plants...
