Applying the dual-isotope conceptual model to interpret physiological trends under uncontrolled conditions

Creator:: Barnard, H. R., Brooks, J. R., and Bond, B. J.
Abstract:: The inter-relationships among δ¹³C and δ¹⁸O in tree ring cellulose and ring width have the potential to illuminate long-term physiological and environmental information in forest stands that have not been monitored. We examine how within-stand competition and environmental gradients affect ring widths and the stable isotopes of cellulose. We utilize...

A comparison of selected parametric and imputation methods for estimating snag density and snag quality attributes

Creator:: Eskelson, B. N. I., Temesgen, H., and Hagar, J. C.
Abstract:: Snags (standing dead trees) are an essential structural component of forests. Because wildlife use of snags depends on size and decay stage, snag density estimation without any information about snag quality attributes is of little value for wildlife management decision makers. Little work has been done to develop models that...

The Cochran airplane seeding experiment : preliminary report

Creator:: Woods, John B. (John Burton), 1890- and Hann, John H.
Abstract:: "One of the basic problems of forest management is that of restoring to productivity denuded areas which cannot be expected to restock through natural means. The most efficient method of regenerating such lands is that method which provides adequate restocking in the shortest time with the least expense. Successful direct...

Bees of the Pacific Northwest : key to bumble bee species for females (Hymenoptera : Apidae : Bombus)

Creator:: Best, Lincoln R., Dunlap, Joshua B., Jackson, August S., Rivers, James W., and Williams, Paul H.
Abstract:: This species key to female bumble bees of the Pacific Northwest provides dichotomous couplets which aid the user in identifying 27 species which occur or have occurred historically, and may still be present in the region. The key architecture is based strongly on the key to species for females found...

Green Revolution Trees: Semidwarfism Transgenes Modify Gibberellins, Promote Root Growth, Enhance Morphological Diversity, and Reduce Competitiveness in Hybrid Poplar

Creator:: Elias, Ani A., Busov, Victor B., Kosola, Kevin R., Ma, Cathleen, Etherington, Elizabeth, Shevchenko, Olga, Gandhi, Harish, Pearce, David W., Rood, Stewart B., and Strauss, Steven H.
Abstract:: Semidwarfism has been used extensively in row crops and horticulture to promote yield, reduce lodging, and improve harvest index, and it might have similar benefits for trees for short-rotation forestry or energy plantations, reclamation, phytoremediation, or other applications. We studied the effects of the dominant semidwarfism transgenes GA Insensitive (GAI)...

Potential financial returns from alternative silvicultural prescriptions in second-growth stands of coastal British Columbia

Creator:: Howard, Andrew F. and Temesgen, H.
Abstract:: This paper reports the findings from a study made of the potential financial returns from nine alternative silvicultural prescriptions applied to four case-study stands of second growth in coastal British Columbia. The objectives were to compare prescriptions based on partial cutting with conventional clear-cutting and to explore the effects of...

Seasonal variation of photosynthetic model parameters and leaf area index from global Fluxnet eddy covariance data

Creator:: Groenendijk, M., Dolman, A. J., Ammann, C., Arneth, A., Cescatti, A., Dragoni, D., Gash, J. H. C., Gianelle, D., Gioli, B., Kiely, G., Knohl, A., Law, B. E., Lund, M., Marcolla, B., van der Molen, M. K., Montagnani, L., Moors, E., Richardson, A. D., Roupsard, O., Verbeeck, H., and Wohlfahrt, G.
Abstract:: Global vegetation models require the photosynthetic parameters, maximum carboxylation capacity (V[subscript cm]), and quantum yield (alpha) to parameterize their plant functional types (PFTs). The purpose of this work is to determine how much the scaling of the parameters from leaf to ecosystem level through a seasonally varying leaf area index...

The effect of local stand structure on growth and growth efficiency in heterogeneous stands of ponderosa pine and lodgepole pine in central Oregon

Creator:: Mainwaring, Douglas B. and Maguire, Douglas A. (Douglas Alan)
Abstract:: Basal area and height growth were analyzed for individual trees in uneven-aged ponderosa pine (Pinus ponderosa Dougl. ex Laws.) and lodgepole pine (Pinus contorta Dougl. ex. Loud.) stands in central Oregon. Basal area growth was modeled as a function of other stand and tree variables to address three general objectives:...
