Debris flows and flood disturbance in small, mountain watersheds

Creator:: Snyder, Kai U.
Abstract:: This study examined debris flows occurring in a 125 km² study area in the Blue River watershed in the western Cascade Mountains of Oregon over a 50-year period. Debris flow occurrence was found to be concentrated in a distinct zone of high activity occupying approximately half of the study area,...

Effects of wood species and prior fungal exposure on the feeding habits of the dampwood termite Zootermopsis angusticollis

Creator:: Mankowski, Mark Edward
Abstract:: The effects of natural preconditioning (source wood), wood species, and previous exposure of wood to two types of fungi on the feeding rates and protozoa survival in the Pacific dampwood termite Zootermopsis angusticollis (Isoptera: Termospidae) were examined under laboratory conditions. Termites were exposed to four wood species that had been...

Litter decay processes and soil nitrogen availability in native and cheatgrass-dominated arid rangelands

Creator:: Harrison, Kristen S.
Abstract:: As large-scale restorations of degraded rangelands are initiated, land managers need to understand how decades of dominance by the invasive annual grass, cheatgrass (Bromus tectorum L.), have altered ecosystem processes. One way to assess such alterations is by observing differences in decay rates, since decomposition is determined by factors such...

The influence of contemporary forest management on stream nutrient concentrations in an industrialized forest in the Oregon Cascades

Creator:: Meininger, William Scott
Abstract:: The increased demand for wood and fiber from a continually shrinking land base has resulted in the use of intensively managed forest plantations. The concentration of timber production on the most suitable sites allows the world's demand for forest products to be met on less land and enable native forests...

Bird communities in managed conifer stands in the Oregon Cascades : habitat associations and nest predation

Creator:: Vega, Robyn M. S.
Abstract:: Green-tree retention is being implemented on state and federal lands in Oregon. Silvicultural prescriptions with tree and snag retention are thought to mimic natural disturbance patterns in the Pacific Northwest more closely than traditional silvicultural practices, which reduce structural complexity. The effects of green-tree retention on native bird species in...

Effects of prescribed fire and silvicultural activities on fuel mass and nitrogen redistribution in Pinus ponderosa ecosystems of central Oregon

Occurrence of ectomycorrhizae on ericaceous and coniferous seedlings grown in soils from the Oregon Coast Range

Creator:: Smith, Jane E. (Jane Elizabeth)
Abstract:: Seedlings of Gaultheria shallon, Pseudotsuga menziesii, Rhododendron macrophyllum and Tsuga heterophylla were grown together in the greenhouse in soils from three young managed Douglas-fir forests in the Oregon Coast Range. The main objectives were 1 )to evaluate the ability of ericaceous plants and overstory conifers to share compatible mycorrhizal fungi...

Systematics, phylogeny, and ecology of Gomphus sensu lato

Creator:: Giachini, Admir J.
Abstract:: The nomenclatural history of Gomphus sensu lato began with Persoon in 1797. Over 200 years species of Gomphus sensu lato have been variously classified also under Cantharellus, Craterellus, Chloroneuron, Chlorophyllum, Gloeocantharellus, Nevrophyllum, and Turbinellus. Species of Gomphus sensu lato have been historically characterized as having aboveground fruiting, fleshy basidiomata with...

Population genetics, systematics, and habitat associations of chanterelles in the Pacific Northwest

Creator:: Dunham, Susie M.
Abstract:: Balancing resource extraction with protection of Pacific Northwest forest ecosystems requires understanding the population biology of ectomycorrhizal fungi. Design of landscape-scale management and research strategies requires understanding genet size, habitat requirements, and dispersal capabilities. The purpose of this dissertation was to gain knowledge about the distribution of genetic variation, systematics,...

Fire history in three vegetation types on the eastern side of the Oregon Cascades

Creator:: Bork, Joyce L.
Abstract:: Historic fire return intervals in three different vegetation types dominated by ponderosa pine (Pinus ponderosa Laws.) were determined using fire scarred trees. Dendrochronological techniques were used to achieve accuracy in dating fire scars on samples collected from six 40 acre plots established in each site. Mean fire return intervals (MFRI)...
