Using a species-centered approach to examine patterns and drivers of avian species richness in the Rogue Basin, Oregon, A 'bird's eye view' : using a species-centered approach to examine patterns and drivers of avian species richness in the Rogue Basin, Oregon

Creator:: Halstead, Katherine E.
Abstract:: The combined effects of habitat loss, degradation, and fragmentation pose a serious threat to Earth's biodiversity, imperiling even relatively common species. 'Habitat' is necessarily a species-specific concept, and investigations of bird diversity relationships and subsequent efforts to prioritize conservation areas, are challenged by the difficulty of estimating complex habitat gradients...

A Landsat time series approach to characterize bark beetle and defoliator impacts on tree mortality and surface fuels in conifer forests

Creator:: Meigs, Garrett W., Kennedy, Robert E., and Cohen, Warren B.
Abstract:: Insects are important forest disturbance agents, and mapping their effects on tree mortality and surface fuels represents a critical research challenge. Although various remote sensing approaches have been developed to monitor insect impacts, most studies have focused on single insect agents or single locations and have not related observed changes...

A Political Ecology Lens for the Nutrition Transition in Rural, Kedougou, Senegal

Creator:: Lucey, Taylor K.
Abstract:: The nutrition transition is a global phenomenon in which populations move from low socioeconomic status (SES) to high SES and from high physical activity to low physical activity. Rising rates of urbanization and non-communicable diseases in West Africa may indicate an advanced phase of the nutrition transition; however, through a...

A Review and Recommendations for Assessing Floodplain Vegetation Recovery Following Stage 0 and Beaver Dam Analog Restorations in the Pacific Northwest

Creator:: Colley, Lara K. M.
Abstract:: Floodplains are a significant and increasingly threatened ecosystem. As restoration projects are implemented more frequently in degraded floodplains, novel methods are emerging with a focus on restoring critical processes in which vegetation plays a key role. The purpose of this paper is two-fold: 1) to develop expectations for vegetation response,...

Aboveground vegetation and viable seed bank of a dry mixed-conifer forest at a wildland-urban interface in Washington state

Creator:: Snider, Gabrielle
Abstract:: Dry coniferous forests in the western United States are experiencing severe wildfires, insect outbreaks, forest disease epidemics and a growing presence of invasive species. Policies strongly emphasize reducing hazardous fuels at the Wildland Urban Interface (WUI) where communities and forests intersect. However, these areas present restoration challenges as they tend...

Adapting to Climate Change on Western Public Lands: Addressing the Ecological Effects of Domestic, Wild, and Feral Ungulates

Creator:: Beschta, Robert L., Donahue, Deborah L., DellaSala, Dominick A., Rhodes, Jonathan J., Karr, James R., O'Brien, Mary H., Fleischner, Thomas L., and Deacon-Williams, Cindy
Abstract:: Climate change affects public land ecosystems and services throughout the American West and these effects are projected to intensify. Even if greenhouse gas emissions are reduced, adaptation strategies for public lands are needed to reduce anthropogenic stressors of terrestrial and aquatic ecosystems and to help native species and ecosystems survive...

Adapting Wastewater Treatment Plants to Sea Level Rise: A Case Study of Half Moon Bay, California

Creator:: Cozzolino, Brittney K.
Abstract:: Wastewater treatment plants around the world are becoming increasingly at risk of sea level rise impacts as these facilities are typically located in low-lying areas to utilize gravity flow for influent (incoming sewage) and effluent (discharged treated sewage). As these risks become realized, treatment plant managers and decision-makers must know...

Age structure, developmental pathways, and fire regime characterization of Douglas-fir/western hemlock forests in the central western Cascades of Oregon

Creator:: Tepley, Alan J.
Abstract:: Descriptions of the fire regime in the Douglas-fir/western hemlock region of the Pacific Northwest traditionally have emphasized infrequent, predominantly stand-replacement fires and an associated linear pathway of stand development, where all stands proceed along a common pathway until reset by the next fire. Although such a description may apply in...

An Analysis of Nutrient Depletion in Douglas-fir Forests of the Oregon Coast Range

Creator:: Siah, Kaveh G.
Abstract:: Nutrient limitation constrains tree growth in many managed forests. Nitrogen (N) is the most common limiting nutrient, but high N supply can shift limitation to other nutrients, particularly phosphorus (P) and the base cations calcium (Ca), magnesium (Mg), and potassium (K). As different soil minerals have different capacities to supply...

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...
