Distribution of bats in Southeast Alaska and selection of day-roosts in trees by Keen’s myotis on Prince of Wales Island, Southeast Alaska

Creator:: Boland, Julia L.
Abstract:: We conducted capture and acoustic surveys for bats in six areas along a latitudinal gradient in Southeast Alaska from mid-May to September in 2005 and we continued surveys on Prince of Wales Island from mid-May to September in 2006. We determined the level of effort required to catch each species...

Impact of exotic Ponderosa pine (Pinus ponderosa Doug. ex Laws.) plantations on water resources in northwestern Patagonia, Argentina

Creator:: Licata, Julian A.
Abstract:: Exotic ponderosa pine (Pinus ponderosa Doug. ex Lawson) plantations are being planted within the natural distribution area of cordilleran cypress (Austrocedrus chilensis (D.Don) Pic. Ser. et Bizzarri) in Patagonia, Argentina. The productivity of these exotic plantations is much greater than that of native forests, suggesting greater water use. Before these...

Fire severity and vegetation response to fire in riparian areas of the Biscuit and B&B Complex Fires, Oregon

Creator:: Halofsky, Jessica E.
Abstract:: Fire is the dominant disturbance process in western U.S. forests, and although effects of fire in upland forests are relatively well-studied, there is little information about fire effects on riparian forests, critical areas of the landscape for both habitat and water quality. This dissertation examines different aspects of fire effects...

Influences of salvage logging on forest birds after fire in the eastern Cascades, Oregon

Creator:: Cahall, Rebecca E.
Abstract:: Previous research examining the influences of post-fire salvage logging on abundances of birds has focused primarily on the response of cavity-nesting species. There is limited research in regard to the impact of salvage logging on a broader range of bird species. In addition, little is known about how different intensities...

Effects of wildfire burn severity on soil microbial communitiesand invasive plant species in the Cascade Range of Oregon

Creator:: Hebel, Cassie L.
Abstract:: Fire suppression in the last several decades has resulted in unprecedented accumulations of organic matter on the landscape, leading to an increase in large, intense wildfires. This study investigated the soil microbial community (using phospholipid fatty acid analysis) across recently burned forests on the eastern slope of the Cascade Range...

Identifying candidate genes associated with cold adaptation in Douglas-fir using DNA microarrays

Creator:: Howe, Dana Kathryn
Abstract:: In forest trees from temperate and boreal regions, cold acclimation is an important adaptive trait that involves changes in gene expression and physiology. Genecological, quantitative genetic, and QTL studies have been used to study the genetics of cold acclimation in Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), but the genes responsible for...

Presence, relative abundance, and resource selection of bats in managed forest landscapes in western Oregon

Creator:: Arnett, Edward B.
Abstract:: I studied presence, relative abundance, and resource selection of bats in managed Douglas-fir (Pseudotsuga menziesii) forests in western Oregon from May through September, 1999–2001. Species richness was not related to elevation, density of snags, or length of edge or perennial streams in sampled landscapes. I captured bats more frequently in...

Geographic variation in central Oregon ponderosa pine (Pinus ponderosa Laws.) : seed germination; seed, wing, and cone morphology; seed color

Creator:: Weber, John C., 1948-
Abstract:: Geographic variation was investigated among 225 locations from five geographically disjunct regions in central Oregon. Characters included: germination speed and uniformity in two test environments differing in stratification period and incubation temperature; weight, three dimensions and three 'angles' of seeds; weight and three dimensions of wings; cone length and scale...

Regeneration and growth of several canopy tree species in the Maya Forest of Quintana Roo, Mexico : the role of competition and microhabitat conditions

Creator:: Sorensen, NaDene S.
Abstract:: We evaluated the regeneration behavior and early growth rates of 10 non-pioneer canopy tree species in medium-height, semi-evergreen dry tropical forest in Quintana Roo, Mexico. These species provide timber and non-timber forest products for local communities and include evergreen and deciduous species with varied dispersal mechanisms. The species were Coccoloba...

Prescribed fire in a ponderosa pine stand in the Blue Mountains, Oregon : relationships among post-fire scolytidae incidence, delayed tree mortality, snag decay dynamics, and woodpecker snag use

Creator:: Kangas, Michael
Abstract:: Delayed tree mortality is an unpredictable occurrence when prescribed burning is implemented. Fire scorched trees may die as the result of crown scorching, stem charring, root injury, bark beetle attack, or through a combination of these factors. This study examined ponderosa pine mortality and the incidence of two bark beetle...
