Climate Change and Management Considerations for the Boreal Forest Zone

Creator:: Habeeb, Gabrielle A.
Abstract:: The boreal forest zone is located in the cool, high latitudes of the earth and represents approximately one third of the world’s remaining forested area. Maintaining the functional capacity of boreal forests is of global importance as they will both affect and be affected by climate change. Boreal forests can...

Societal Responses to Using Genetic Engineering for Mitigating Chestnut Blight and Restoring American Chestnut Trees

Creator:: Petit, Joshua D.
Abstract:: Forests face health threats from pests and diseases (e.g., mountain pine beetle, emerald ash borer, chestnut blight [CB], Swiss needle cast), and other issues such as climate change. Interventions such as genetic engineering (GE) have shown promise for mitigating some of these threats. CB, for example, has impacted most American...

Fuel Treatments of Ponderosa Pine (Pinus ponderosa) in the Blue Mountains of Eastern Oregon : A Mycorrhiza Perspective

Creator:: Hart, Benjamin T. N.
Abstract:: Over the course of the last century, a successful history of fire suppression has contributed to unsuccessful present day control over wildfire. In the absence of fire and the janitorial and ecological services it provides, drier inland forests are shifting in species composition and exceeding densities that cannot survive and...

Identifying factors driving sensitivity to fragmentation in forest breeding songbirds

Creator:: Valente, Jonathon J.
Abstract:: Habitat loss and fragmentation are the greatest threats to biodiversity worldwide. Fragmentation impacts landscape configuration, resulting in a larger number of patches that are smaller in size and further apart from one another. Island biogeography and metapopulation theory predict populations in these remnant patches should be smaller, have higher extinction...

Top-down and Bottom-up Controls of Adelges tsugae in the Pacific Northwest Inform Its Biological Control in Eastern North America

Creator:: Rose, Alexander
Abstract:: The hemlock woolly adelgid (Hemiptera: Adelgidae: Adelges tsugae; HWA) is an invasive and damaging pest on hemlock in eastern North America. HWA is native to the Pacific Northwest, where it does not damage hemlock. In support of classical biological control of HWA in eastern North America, abundances of native predators...

Spruce-Fir Moss Spider (Microhexura Montivaga) Monitoring Plan

Creator:: Sacco, Christopher
Abstract:: On June 20, 2019, the U.S. Fish and Wildlife Service (USFWS) announced it would conduct a 5-year status review of the Spruce-Fir Moss Spider as part of the process mandated by the Endangered Species Act. Although the Spruce-Fir Moss Spider has been listed as endangered since 1994, minimal research has...

An examination of climate and land-use change as drivers of population dynamics in breeding birds

Creator:: Kim, Hankyu
Abstract:: Anthropogenic land-cover change and climate change are the major drivers of the steep loss of avian biodiversity in past decades. Loss of avian biodiversity is predicted to result in the reduction of ecosystem services and ecological functions. Identifying avian population changes and the drivers of these trajectories is essential for...

Comparison of transect call-point and acoustic sampling of white-headed woodpeckers (Dryobates albolarvatus) within mixed-conifer and ponderosa pine (Pinus ponderosa) forest types

Creator:: Gaylord, Marie A.
Abstract:: We used occupancy modeling to compare the detection probabilities of white-headed woodpeckers using transect call-point versus ARU surveys. We then used the estimated detection probability for each survey method to evaluate the number of surveys needed to infer white-headed woodpeckers absence under different levels of certainty.

Assisted Migration in the Colorado Subalpine Forest

Creator:: Najim, Tara
Abstract:: This capstone study reports on global warming-induced changes to the Colorado subalpine zone climate and disturbance regimes. It assesses the impacts of these changes upon the dominant subalpine tree species and summarizes future species distribution modeling for these and other nearby species potentially suitable for the future subalpine zone in...

Using Cognitive Appraisal Theory and the Means-Ends Approach to Explore Relationships Among Perceived Tourism Impacts, Livelihoods, Quality of Life, and Residents’ Support for Tourism

Creator:: Parada Torres, Javier A.
Abstract:: Understanding residents’ perceptions of and support for tourism is essential for sustainable tourism development and management. Research has shown that perceptions of tourism impacts are related to residents’ support for tourism. It is generally accepted that perceived tourism impacts predict support for tourism, as explained by social exchange theory. However,...
