Effects of current velocity, irradiance, and herbivory on algal assemblages in laboratory streams

Creator:: Steinman, Alan D.
Abstract:: Effects of current velocity, irradiance, and grazing on the biomass, taxonomic structure, physiognomy, and chemical composition of lotic algal assemblages were investigated. Four experiments, lasting 32 to 75 days, were conducted in laboratory streams to determine how these factors affect algal assemblages singly, and in concert with each other. Regardless...

The genus Leucogaster (Basidiomycetes, Leucogastraceae)

Creator:: Fogel, Robert Dale
Abstract:: Three provisional species are described as new: Leucogaster couchii, L. gelatinosus, and L. microsporus. Leucophlebs candida is transferred to Leucogastef, completing the transfer of all Leucophlebs species to Leucogaster. L. columellatus is transferred to Sclerogaster. L. longisterigmatus is synonymized with L. rubescens, L. foveolatus with L. odoratus, and L. fulvimaculatus...

Impacts of ponderosa pine forest restoration treatments on the ectomycorrhizal fungal community and fine root biomass in the Blue Mountains of Oregon

Creator:: Smith, Jane E. (Jane Elizabeth)
Abstract:: Before the arrival of Euro-Americans, the inland Pacific Northwest was settled by native people whose frequent intentional burning of the landscape promoted open stands dominated by large fire-resistant ponderosa pine. Fire suppression for nearly a century, livestock grazing, and logging of the largest trees has resulted in forests characterized by...

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...

Benthic algal communities of the Metolius River

Creator:: Sherman, Barbara Jane Powell, 1938-
Abstract:: Samples of benthic algae were collected from the Metolius River of central Oregon at two-week intervals between April 15, 1967 and March 9, 1968. Species of filamentous algae and diatoms present were recorded for every sampling station on each sampling date. Permanent mounts of diatom frustules were prepared. This sampling...

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,...

Growth and replacement patterns occuring among selected dominant species associated with plant succession on Douglas fir clear-cuts

Creator:: Robinson, Myles Canby
Abstract:: Growth and replacement patterns of four successionally important species occurring on Douglas fir clear-cuts were investigated from September 1964 to June 1967. The study was carried out on the Marys Peak watershed located near Corvallis, Oregon. Species used in the study include Holcus lanatus, Senecio jacobaea, Lotus crassifolius var. subglaber,...

Mediation of conifer root growth by mycorrhizal fungi and plant growth regulators

Creator:: Scagel, Carolyn F.
Abstract:: Many mycorrhizosphere microorganisms can produce plant growth regulating compounds in vitro. Plant growth regulating compounds are known to mediate root growth and development. In reforestation practices, conifer tree seedling growth and survival are linked to rapid root growth and development after outplanting. Multifactorial experiments were conducted to document variations in...

Conservation genetics of Kincaid's lupine : a threatened plant of western Oregon and southwest Washington grasslands

Creator:: Severns, Paul M.
Abstract:: Kincaid's lupine (Lupinus oreganus Heller) is a federally listed threatened species native to remnant grassland of western Oregon and southwestern Washington, and is the primary larval host plant of a once thought extinct butterfly, Plebejus icarioides fenderi Macy. Past studies concerning Kincaid's lupine reproduction suggested that populations may suffer reductions...
