Analyzing patterns of woody plant richness at multiple spatial scales with modeled photosynthesis

Creator:

Swenson, Jennifer J.

Abstract:

The hump-shaped relationship that predicts highest species richness (species/unit area) at intermediate levels of productivity was examined for woody plants across the Pacific and Inland Northwest of the U.S. Many studies have examined this relationship at regional scales, but commonly use species range maps and surrogate measures of productivity (e.g....

Ionic balance and the constituent organic acids of current-year foliage of western redcedar, western hemlock, and Douglas-fir seedlings

Creator:

Graff, Joseph Edward

Abstract:

Western redcedar, western hemlock, and Douglas-fir seedlings were transplanted into pots in one of two soils representative of high and low levels of available NO3 (and total N). The soils were collected from sites at Cascade Head (Oregon Coast) and Wind River (Washington Cascades). Whole plant and component relative dry...
