An investigation of vegetation : hydrology interactions in watershed 1 at the H.J. Andrews Experimental Forest

Creator:

Bredensteiner, Kim C.

Abstract:

For management purposes, it would be useful to be able to predict streamflow response to forest practices in small, unmonitored basins. The primary objective of this study is to investigate the influence of early successional vegetation on summer streamflow levels. The long-term data records from watershed 1 at the H.J....

Biology, epidemiology, and biological and chemical control of Phytophthora vignae

Creator:

Fernando, W. Gerard Dilantha

Abstract:

Phytophthora vignae, causal agent of stem and root rot of cowpea (Vigna unguiculata), was reported for the first time in Sri Lanka. The pathogen was found in cowpea field soils from 3 of 5 geographic regions sampled. Only one site however, had plants exhibiting disease symptoms. Of the eight cowpea...

Evolution and ecology of the Ceanothus-Frankia symbiosis

Creator:

Jeong, Soon-Chun

Abstract:

The evolutionary relationship between Frankia and actinorhizal plants was evaluated by reconstructing molecular phylogenetic trees from nifH, 16S rDNA, and rbcL nucleotide sequences. Subgroupings in Frankia phylogenetic trees reconstructed from nifH and from 16S rDNA sequences were consistent in terms of plant origins of Frankia strains. Although the branching order...

Ecological assessment after the addition of genetically engineered Klebsiella planticola SDF20 into soil

Creator:

Holmes, Michael T.

Abstract:

The objectives in this research were to assess whether Klebsiella planticola SDF20 could survive in soil and result in ecological effects to soil foodweb organisms and plant growth. Four experiments were conducted using soil microcosms. Klebsiella planticola SDF20 has been genetically engineered to produce ethanol from agricultural waste for use...

Epidemiology and population biology of Inonotus tomentosus as a pathogen of forests of British Columbia

Creator:

Lewis, Katherine JoAnn

Abstract:

The root disease fungus Inonotus tomentosus, common in the old growth boreal forests of British Columbia, poses a threat to the health of second growth forests established on sites with a previous history of root disease. Colonized stumps occur in groups of 1 to 6; the groups are clumped within...

Taxomony and mycorrhizal ecology of the desert truffles in the genus Terfezia

Creator:

Alsheikh, Abdulmagid M.

Abstract:

Mycorrhizal fungi in arid and semiarid rangelands have received little study in southwest Asia and north Africa, although they are important in food production and rangeland productivity. The desert truffles of the genera Terfezia and Tirmania form fruiting-bodies and mycorrhizae with rangeland plants. This thesis treats the taxonomy and the...

The reproductive ecology of the pacific yew (Taxus brevifolia nutt.) under a range of overstory conditions in western Oregon

Creator:

DiFazio, Stephen P.

Abstract:

The influence of overstory openness on the reproductive ecology of Pacific yew (Taxus brevifolia Nutt.) was investigated on 4 sites in western Oregon over 2 years. The breeding system of T. brevifolia was found to deviate from pure dioecy under a broad range of canopy and site conditions. Production of...

Effects of fire on seedling establishment in upland prairies in the Willamette Valley, Oregon

Creator:

Maret, Mary P.

Abstract:

Prior to European settlement, native prairie dominated the landscape of the Willamette Valley. Today, due to urbanization, agriculture, and the cessation of burning, only isolated remnants of these grasslands still exist. In response to conservation concerns, there has been a move to restore the remaining prairies in the Willamette Valley,...
