Genetics of cold hardiness in a cloned full-sib family of coastal Douglas-fir

Creator:: Anekonda, T. S., Adams, W. T., Aitken, S. N., Neale, David B., Jermstad, K. D., and Wheeler, N. C.
Abstract:: Variation in cold-hardiness traits, and their extent of genetic control and interrelationships, were investigated among individuals (clones) within a single large full-sib family of coastal Douglas-fir (Pseudotsuga menziesii var. menziesii (Mirb.) Franco) from Oregon. Cold injury to needle, stem, and bud tissues was evaluated in fall 1996 and spring 1997...

Conifer DBMagic: a database housing multiple de novo transcriptome assemblies for 12 diverse conifer species

Creator:: Lorenz, W. Walter, Ayyampalayam, Savavanaraj, Bordeaux, John M., Howe, Glenn T., Jermstad, Kathleen D., Neale, David B., Rogers, Deborah L., and Dean, Jeffrey F. D.
Abstract:: Conifers comprise an ancient and widespread plant lineage of enormous commercial and ecological value. However, compared to model woody angiosperms, such as Populus and Eucalyptus, our understanding of conifers remains quite limited at a genomic level. Large genome sizes (10,000–40,000 Mbp) and large amounts of repetitive DNA have limited efforts...

Models of presence-absence estimate abundance as well as (or even better than) models of abundance: the case of the butterfly Parnassius apollo

Creator:: Gutiérrez, David, Harcourt, Jennifer, Díez, Sonia B., Gutiérrez Illán, Javier, and Wilson, Robert J.
Abstract:: Models relating species distribution records to environmental variables are increasingly applied to biodiversity conservation. Such techniques could be valuable to predict the distribution, abundance or habitat requirements of species that are rare or otherwise difficult to survey. However, despite widely-documented positive intraspecific relationships between occupancy and abundance, few studies have...

Diversity and productivity of hypogeous fungal sporocarps in a variably thinned Douglas-fir forest

Creator:: Colgan, Wesley, Carey, Andrew B., Trappe, James M., Molina, Randy, and Thysell, David
Abstract:: Although ecosystem management techniques are designed to enhance species diversity in managed forests, no comprehensive study has been conducted to evaluate effects of such techniques on diversity and productivity of hypogeous fungi (truffles). During this study, truffles were collected in a 55- to 65-year-old Douglas-fir forest from March 1993 through...

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)...

Crown profile equations for stand-grown western hemlock trees in northwestern Oregon

Creator:: Marshall, David D., Johnson, Gregory P., and Hann, David W.
Abstract:: Crown profile equations were developed for stand-grown western hemlock (Tsuga heterophylla (Raf.) Sarg.) in northwest Oregon. The profile model uses a segmented approach, dividing the crown into an upper and lower portion at the point of the largest crown width (LCW). The model explains about 86% of the variation in...

Shared compatibility of ectomycorrhizae on Pseudotsuga menziesii and Betula papyrifera seedlings grown in mixture in soils from southern British Columbia

Creator:: Simard, Suzanne W., Molina, Randy, Smith, Jane E., Perry, David A., and Jones, Melanie D.
Abstract:: Seedlings of Pseudotsuga menziesii (Mirb.) Franco and Betula papyrifera Marsh. were grown in the greenhouse in monoculture and dual culture in soils collected from a young mixed species plantation in the southern interior of British Columbia. The objectives of the study were (i) to evaluate the ability of P. menziesii...

Evaluation of nonspatial approaches and equation forms used to predict tree crown recession

Creator:: Hann, David W. and Hanus, Mark L.
Abstract:: Two nonspatial approaches for modeling tree crown recession (ΔHCB) were evaluated by using 5341 observations from Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco). The first approach applies a static height-to-crown-base (HCB) equation at the start and end of the growth period and uses the difference in these predictions as an estimate of...

Clonal expansion and seedling recruitment of Oregon grape (Berberis nervosa) in Douglas-fir (Pseudotsuga menziesii) forests: comparisons with salal (Gaultheria shallon)

Creator:: Huffman, David W. (William), 1962- and Tappeiner, John C.
Abstract:: Seedling regeneration and morphology of Oregon grape (Berberis nervosa Pursh) and salal (Gaultheria shallon Pursh) were studied in thinned and unthinned Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) stands in the central Coast Range, Oregon. Above- and below-ground growth of both species were significantly and negatively correlated with stand density. Oregon grape...
