Spatial and temporal dynamics of the Douglas-fir bark beetle (Dendroctonus pseudotsugae, Hopk.) in the Detroit Ranger District, Oregon : a landscape ecology perspective

Creator:: Powers, Jennifer Sarah
Abstract:: I developed a conceptual model of Douglas-fir bark beetle dynamics and associated host mortality across spatial and temporal scales. I proposed that a hierarchy of factors influence host resistance to attack at different spatial scales. I then tested this model by measuring the association between the occurrence of beetle-kill and...

Carbon dynamics following landscape fire: influence of burn severity, climate, and stand history in the Metolius Watershed, Oregon

Creator:: Meigs, Garrett W.
Abstract:: Fire is a fundamental disturbance that drives terrestrial and atmospheric carbon dynamics. Previous studies have quantified fire effects on carbon cycling from local to global scales but have focused nearly exclusively on high-severity, stand-replacement fire. Since 2002, variable-severity wildfires have burned more than 65 000 ha across the east slope...

The ecological legacy of Indian burning practices in southwestern Oregon

Creator:: Carloni, Kenneth R.
Abstract:: Two research questions are posed: (1) How have ecosystem conditions changed through time in southwestern Oregon? (2) How have culture-driven and climate-driven processes contributed to ecosystem change in southwestern Oregon? A brief introduction to the Little River study area is followed by a cultural and ecological history of the watershed....

Impact of Armillaria and annosus root diseases on stand and canopy structure, species diversity, and down woody material in a central Oregon mixed-conifer forest

Creator:: Fields, Kristen L. N.
Abstract:: White and grand fir are both valuable components of the mixed-conifer stand structure managed for late-successional reserves in central Oregon. However, they are often short-lived species because of high susceptibility to root diseases, defoliating insects, bark beetles, and wildfire. This study focuses on the effects of root diseases caused by...

Habitat relationships of small terrestrial vertebrates and invertebrates in managed forests in the southern Oregon Cascades

Creator:: McDade, Kirsten Ayn
Abstract:: Silviculture systems that involve commercial thinning may provide higher quality wildlife habitat than traditional clearcut systems, yet such systems have not been vigorously tested. This prospective study examined forest floor animal abundance and habitat relationships under three different silviculture conditions: clearcuts, commercial thins, and uncuts. Eighteen stands, six per treatment,...

The use of burned forest by breeding birds following the Biscuit Fire in southwest Oregon

Creator:: Donaghy Cannon, Michelle M.
Abstract:: Fire severity is hypothesized as an important driver of bird responses to wildfire. For those species that typically respond negatively to increasing severity, Accessibility of high-severity burned forest may be dependent on the proximity of unburned or low-severity burned forest to meet all of the needs of breeding bird species...

Carbon storage in a Pacific Northwest conifer forest ecosystem : a chronosequence approach

Creator:: Janisch, Jack E.
Abstract:: As concern over global warming intensifies, sequestration and storage of atmospheric CO2 has become an important scientific and policy issue. Confusion persists, however, over interpretation of forest carbon (C) source-sink dynamics, in part because conclusions drawn depend on temporal and spatial scales of analysis (e.g. day-week scale vs. successional-scale), type...

Response of wood-boring beetles (Coleoptera: Buprestidae, Cerambycidae) to prescribed understory burning in mixed-conifer stands of southwestern Oregon

Creator:: Duane, Maureen V.
Abstract:: Prescribed burning is increasingly being used as a management tool to reduce potential fuels on the forest floor and promote stand vigor through removal of dense, crowded vegetation. Because fire affects both the standing vegetation and the amount of downed wood in the ecosystem, it is imperative to examine how...

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...

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...
