Undergraduate Thesis
Biomass dynamics of dead Douglas-fir and western hemlock boles in mid-elevation forests of the Cascade Range

Creator:

Graham, Robin Lee Lambert

Abstract:

The rate and manner of bioniass loss from decomposing Douglas-fir and western hemlock boles in mid-elevation forests of the central Cascade Range were measured. Bole bark and wood were considered separately. Loss of bole wood due to respiration was measured by change in bole wood density. Loss of bole wood...

Dissertation
Levels of asymbiotic nitrogen fixation in leaf litter in Northwest forests

Creator:

Heath, Brian E.

Abstract:

Asymbiotic N fixation in leaf litter in the Northwest was assayed by acetylene reduction. Annual N input measured by periodic sampling in a young Willamette Valley Douglas-fir plantation at Adair, Oregon was 1.08 +_.13 kg/ha. Using different calculating methods, six other annual estimates at the Adair site ranged from 0...

Research Paper
Basidiomycetes in the primary decomposition of forest floor litter

Creator:

Minyard, Patrick Lealand, Driver, Charles H., 1921-, U.S. International Biological Program. Coniferous Forest Biome, and University of Washington

Abstract:

Basidiomycete fructifications collected at the research site were Cortina sp., Amanita sp., Armillaria sp., Polyporus abietinus, Fomes annosus, Poria spp., Fomes pinicola, Coprinus spp., and Cantharellus cibarius. Fungal organisms isolated from partially decomposed needles were phycomycetes and Fungi Imperfecti, and organisms isolated from undecomposed needles were primarily yeasts ... The...
