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

Creator:

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,...

Lichen response to the environment and forest structure in the western Cascades of Oregon

Creator:

Martin, Erin P.

Abstract:

Lichens are an important part of the biota in western Oregon forests, where they perform valuable ecological roles and contribute significantly to biodiversity. Lichens in western Oregon are threatened by a number of factors including air pollution and land use practices. If we wish to maintain the persistence of lichens...

The association of epiphytic macrolichens and bryophytes with riparian stand types along a valley continuum, Oregon Coast Range

Creator:

Ruchty, Andrea M.

Abstract:

I surveyed epiphytic macrolichens and bryophytes in six stands in each of seven riparian stand types in the Oregon Coast Range. This study (Chapter 2) describes the association of epiphytes with stand types and the corresponding potential of forest canopy conversions to affect epiphyte communities. Species composition, diversity, and representation...

Analysis and prediction of patterns in lichen communities over the western Oregon landscape

Creator:

Peterson, Eric B.

Abstract:

The diverse lichen flora of the Pacific Northwest is being impacted by population growth and by forest management practices. Accumulating information about our lichen flora will improve our conservation strategies. This dissertation first collects information to improve our understanding of how lichen communities vary among forests of differing structure, and...

Distributional patterns and taxonomic structure of diatom assemblages in Netarts Bay, Oregon

Creator:

Whiting, Mark Carlos

Abstract:

Epiphytic, planktonic and benthic diatom assemblages were investigated in Netarts Bay, Oregon. Samples were collected for a one-year period from February 1980 to March 1981. A planktonic flora was observed only during periods of offshore enrichment when marine neritic species were abundant and were transported into the bay by tidal...

Biology and management of Meloidogyne chitwoodi using oxamyl on potato in the western United States

Creator:

David, Nicholas L.

Abstract:

Field trials were conducted during 2001 to 2003 to investigate soil population dynamics of Meloidogyne chitwoodi, tuber symptom suppression using oxamyl, and post-harvest tuber symptom development on short-season potato varieties Russet Norkotah and Russet Nugget (San Luis Valley only). The experiments were located in the San Luis Valley in Colorado,...

Identification of Endogenous and Exogenous Pararetroviruses in Red Raspberry (Rubus idaeus L.) and Blueberry (Vaccinium corymbosum L.)

Creator:

Diaz Lara, Alfredo

Abstract:

The Pacific Northwest (Oregon and Washington in the United States and British Columbia in Canada) is one of the major producers of red raspberry (Rubus idaeus L.) and blueberry (Vaccinium corymbosum L.) in the world. The expansion of growing area with these crops has resulted in the emergence of new...

Biosystematic studies of Phacelia capitata (Hydrophyllaceae), a species endemic to serpentine soils in southwestern Oregon

Creator:

Shelly, J. Stephen

Abstract:

Phacelia capitata Rruckeberg is a member of the Phacelia magellanica polyploid complex (species group Magellanicae), a group of wide-ranging, polymorphic perennials in western North America related to the South American P. secunda (= P. magellanica). The purpose of this project was to determine, to the extent possible, the interrelationships of...

Effects of Preinoculation with VAM fungi isolated from different sites on plant tolerance to salinity in soils amended with sodium chloride

Creator:

Cantrell, Isabella Cardona

Abstract:

The hypothesis that inoculation of transplants with vesicular-arbuscular mycorrhizal (VAM) fungi before planting into saline soils would alleviate salt effects on growth and productivity was tested on lettuce (Lactuca sativa L.) and onion (Allium cepa L.). A secondary hypothesis was that the fungi isolated from a saline soil would be...

Phylogeny, cospeciation, and host switching in the evolution of the ascomycete genus Rhabdocline on Pseudotsuga and Larix (Pinaceae)

Creator:

Gernandt, David S.

Abstract:

The relative role of cospeciation and host switching in the phylogenetic history of ascomycete foliar symbionts is addressed in the orders Leotiales and Rhytismatales, fungi associated predominantly with Pinaceae (Coniferales). Emphasis is placed on comparing the evolution of the sister genera Pseudotsuga and Larix (Pinaceae) with that of the pathogenic...
