An interdisciplinary framework for evaluating 19th century landscape paintings for ecological research

Creator:: Warren, Dana R., Loeb, Harper M., Betjemann, Peter, Munck, Isabel A., Keeton, William S., Shaw, David C., and Harvey, Eleanor J.
Abstract:: As we contemplate the future of forest landscapes under changing climate conditions and land-use demands, there is increasing value in studying historic forest conditions and how these landscapes have changed following past disturbances. Historic landscape paintings are a potential source of data on preindustrial forests with highly detailed, full-color depictions...

Beetle Outbreaks and Wildfires: Drivers of Fire Severity, Recruitment, and Structural Legacies for Sub-boreal Forests in British Columbia

Creator:: Talucci, Anna C.
Abstract:: Bark beetle outbreaks have left a legacy of tree mortality across fire-prone landscapes of western North America that could influence how these forests will burn and regenerate. While research has been focused on forests in the western United States, the potential interactions between mountain pine beetle (MPB) outbreaks and wildfires...

Patterns of tree establishment and vegetation composition in relation to climate and topography of a subalpine meadow landscape, Jefferson Park, Oregon, USA

Creator:: Zald, Harold S. J.
Abstract:: The forest alpine tundra ecotone (FTE, also known as alpine treeline or subalpine parkland), is a conspicuous feature of mountain landscapes throughout the world. Climate change-driven increases in temperature are believed to result in FTE movement and tree invasion of subalpine meadows, which have been documented throughout the Northern Hemisphere...

Fire Refugia Function and Composition in Dry Mixed-Conifer Forests of Oregon’s Blue Mountains

Creator:: Downing, William M.
Abstract:: Contemporary fire effects are raising concerns about the resistance and resilience of dry mixed-conifer forests to large wildfires. Fire refugia – unburned or low-severity patches within fire perimeters – are understudied components of post-fire mosaics that may be key drivers of forest recovery following high-severity fire. Little is known about...

Karuk Stewardship of Xánthiip (black oak, Quercus kelloggii) in the Western Klamath Mountains: Development of an Ecocultural Monitoring Protocol

Creator:: Thoreson, Jessie
Abstract:: My thesis is an exploration of xánthiip (Karuk for black oak, Quercus kelloggii) restoration within the Karuk Tribe’s Ancestral Territory in present-day northwestern California. Black oak is a cultural keystone species for the Karuk and has been chosen as one of the species to guide Tribally led forest restoration work...

Historical forest succession and disturbance dynamics in Coastal Douglas-fir forests in the southern western Cascades of Oregon

Creator:: Merschel, Andrew G.
Abstract:: Coastal Douglas-fir (Pseudotsuga menziesii var menziesii) forests are extensive west of the crest of the Cascade Mountains in Oregon and Washington and are renowned for their productivity, biodiversity, and the ecosystem services they provide. Increasing wildfire activity in recent years including the extensive 2020 Labor Day fires, and a warming...

Biodiversity Responses in Early Seral Forests of the Klamath-Siskiyou: Comparisons with Birds, Bees, and Ground Beetles among Post-fire, Salvage Logging, and Intensive Forest Management Environments

Creator:: Frank, Graham S.
Abstract:: Early seral forests regenerating from stand-replacing disturbances provide unique habitat for many species in productive, temperate forest landscapes and contribute to supporting biodiversity. Population declines in some species associated with early seral forests have prompted concerns about the conservation of these habitats, particularly the characteristic structural and compositional complexity associated...

Competition release and climate change effects on a moisture-demanding tree species in a dry system

Creator:: Seager, S. Trent
Abstract:: Climate change and the increase in meteorological drought have generated global concern over the persistence of ecosystems already in decline from decreased moisture. Evidence suggests dryland ecosystems have been more impacted by drought because of their tightly coupled growth-water relationships and high sensitivity to environmental shift. Removal of competing vegetation...

Efficacy of Empirical Seed Zones: Pseudoroegneria Spicata Reproductive Phenology & Seedling Stage Traits

Creator:: Prive, Kathryn A.
Abstract:: Ecological restoration is needed to mitigate losses to biodiversity. Restoration success is enhanced through the use of native plant materials that are genetically diverse and locally adapted. Seed transfer zones have been developed to delineate geographic areas where native seed can be collected and distributed with reduced risk of maladaptation....

Analysis of the impact of certification on cocoa production in Peru through a literature review

Creator:: Chiroque Chiroque, Junior A.
Abstract:: The Peruvian cocoa sector has been growing quickly since the beginning of this century due to international demand for this commodity together with concentrated international cooperation, including NGOs and governmental agencies. Similarly, certification among cocoa producers has been growing quickly. Little is known regarding how certification impacts environmental and socioeconomic...
