Characterization of lignocellulose decomposition in stream wood samples using ¹⁴C and ¹⁵N techniques

O Criador:: Aumen, Nicholas G.
Resource Type:: Dissertation

Forest structure and regeneration in the Tsuga heterophylla - Abies amabilis transition zone, central Western Cascades, Oregon

O Criador:: Stewart, Glenn H.
Abstract:: The dynamics of stands in the mid-elevation old-growth Douglas-fir (Pseudotsuga menziesii) forests of the central western Oregon Cascade Range were investigated using stand structure analysis. Trees with different growth rates were commonly present in the same stand, which resulted often in a weak correlation between tree diameter and age. Thus,...

Silvicultural impacts of sheep grazing in Oregon's Coast Range

O Criador:: Leininger, Wayne C.
Abstract:: A three-year investigation was conducted during 1980-1982 to evaluate the potential of using herded sheep as a silvicultural tool to suppress brush in Douglas-fir (Pseudotsuga menziesii) plantations of Oregon's Coast Range. Sheep browsing of Douglas-fir was highest in May soon after bud break. Averaged over the 2 years of grazing,...

Habitat relationships of birds and young-growth Douglas-fir in northwestern California

O Criador:: Marcot, Bruce G.
Abstract:: Ninety-one species of birds were surveyed in grass/forb, early and late shrub/sapling, pole, and medium sawtimber stages of young-growth Douglas-fir in northwestern California; patterns of bird distribution and abundance were related to habitat conditions and even-age silvicultural treatments. Seven species (band-tailed pigeon, western wood pewee, dusky flycatcher, western bluebird, fox...

Ultrastructure of parenchyma and sclereids in Douglas-fir [Pseudotsuga menziesii(Mirb.)Franco] bark

O Criador:: Dougal, Edward Francis
Abstract:: Because Douglas-fir [Pseudotsuga menziesii(Mirb.)Franco] bark is a raw material produced in our renewable forests along with wood, an understanding of the ultrastructure of bark cells is of paramount importance if wood technologists are to utilize the bark to the fullest potential. The objectives of this study were to develop microscopic...

Microdistribution and retention of chloropicrin in wood

O Criador:: Goodell, Barry Scott
Abstract:: Quantitative and qualitative information on the retention of chlorinated residues in chloropicrin treated wood is lacking. Retention of chloropicrin and its chemical breakdown products in wood, and the effects of chloropicrin treatment of wood on invading decay fungi are explored in this thesis. Chlorinated residues in amounts up to 1.5%...

Physiological control of fine root turnover in Douglas-fir

O Criador:: Marshall, John D. (John David), 1956-
Abstract:: To determine whether shading increases drought-induced root mortality by changing the chemical composition of roots, I conducted an experiment in which high and low light treatments in combination with high and low soil moisture treatments were applied to seedlings of Douglas-fir (Pseudotsuqa menziesii Mirb. Franco). Because synthesis of suberin (a...
