Factors affecting the inoculum potential of VA and ectomycorrhizal fungi in forest soils of southwest Oregon and northern California

Creator:: Parke, Jennifer Lee
Resource Type:: Dissertation
Full Text:: Jennifer Lee Parke for the degree of Doctor of Philosophy in Botany and Plant Pathology presented on July

A biosystematic study in the genus Aster, section Aster, in western North America

Creator:: Dean, Milton Lee
Abstract:: A biosystematic investigation was undertaken in 15 species and three subspecies of the genus Aster, in western North America. Previous studies had been based entirely on external morphological features, and it was believed that much could be learned about the natural affinities of the taxa by exploring their cytological and...

Serpentine and non-serpentine edaphic ecology and the recovery of Lomatium cookii (Apiaceae), an endangered endemic of southwest Oregon

Creator:: Silvernail, Ian S.
Abstract:: The role of unusual geologies in plant distribution and form is well-known. Serpentine (ultramafic) soils exert a particularly strong influence on plants, as evidenced by a high level of endemism and the morphological and physiological traits displayed in adaptation to the extraordinary chemistry of these substrates. Adaptation may lead to...

Evolutionary relationships and an investigation of sympatric speciation within Limnanthaceae

Creator:: Meyers, Stephen C.
Abstract:: Limnanthes floccosa ssp. floccosa and L. floccosa ssp. grandiflora are two of five subspecies of Limnanthes floccosa endemic to vernal pools in southern Oregon and northern California. Three seasons of monitoring natural populations have quantified that L. floccosa ssp. grandiflora is always found growing sympatrically with L. floccosa ssp. floccosa...

Annual cycles of ecological disturbance and recovery underlying the subarctic Atlantic spring plankton bloom

Creator:: Behrenfeld, Michael J., Doney, Scott C., Lima, Ivan, Boss, Emmanuel S., and Siegel, David A.
Abstract:: Satellite measurements allow global assessments of phytoplankton concentrations and, from observed temporal changes in biomass, direct access to net biomass accumulation rates (r). For the subarctic Atlantic basin, analysis of annual cycles in r reveals that initiation of the annual blooming phase does not occur in spring after stratification surpasses...

The fate of organic and inorganic nitrogen inputs in an old-growth forest of the central Oregon Cascade Range

Creator:: Holub, Scott M.
Abstract:: Forests in the Pacific Northwest receive very little nitrogen through atmospheric deposition and thus studying the nitrogen cycle in this region can provide insights into how the unpolluted nitrogen cycle functions. I examined the fate of organic nitrogen versus inorganic nitrogen and the effect of tamlins on N retention by...

Molecular phylogenetic analyses of Riccia and Marchantiales

Creator:: Wheeler, John A. (John Allen)
Resource Type:: Dissertation

Succession and certain adaptive features of plants native to the sand dunes of the Oregon coast

Creator:: Kumler, Marion Lawrence, 1941-
Abstract:: The vegetation of the Oregon coast is characterized by a variety of stages of plant succession which are repeated widely throughout the sand dune area. During the years from 1960 to 1963 the gradation of upland sand dune succession was studied on 48 plots within a 150 mile section of...
