A high-performance Web Graphics Library-based Automatic Identification System data visualization platform

Creator:: Chen, Likun
Abstract:: The magnitude of global AIS data exceeds the capability of conventional in-browser graphic rendering technologies like Scalable Vector Graphics (SVG) and Canvas. Normal practices of rendering AIS data in browser will either suffer from low frame rates or will have to limit the total number of visual elements. In this...

Automated web-based analysis and visualization of spatiotemporal data

Creator:: Keon, Dylan B.
Abstract:: Most data are associated with a place, and many are also associated with a moment in time, a time interval, or another linked temporal component. Spatiotemporal data (i.e., data with elements of both space and time) can be used to assess movement or change over time in a particular location,...

Biogeography of nonindigenous species: from description to prediction

Creator:: Reusser, Deborah A.
Abstract:: Nonindigenous species are a major threat to the ecological integrity and biodiversity of marine and estuarine ecosystems. To become a successful invader, species must pass through four phases: (1) survive transport, (2) survive release, (3) establish a population, and (4) expand their range. To better understand these processes, an integrated...

Advancements in the Monitoring of Forests and Quantification of Live Aboveground Biomass Using Moderate Resolution Spaceborne Multispectral Imagery and Synthetic Aperture Radar Data

Creator:: Kilbride, John B.
Abstract:: The objective of this dissertation is to enhance the monitoring of forest ecosystems through the utilization of remotely sensed data to address the exigencies posed by the Anthropocene. On a global scale, rising temperatures and fluctuating precipitation patterns have strained forests and produced shifts in natural disturbance regimes. Additionally, the...

Climate Variability and Plant-Pollinator Networks in the Cascade Range, Oregon

Creator:: Vickers, Melinda
Abstract:: Worldwide, networks of plants and pollinators are faced with the threat of climate change. The extent of this threat and the degree of adaptability is not yet understood. In Oregon, climate change is predicted to bring hotter and drier summers which may have consequences for pollinators and the resources they...

Introducing and validating a high-throughput bud break sensor

Creator:: Kleinknecht, George J.
Abstract:: Bud break is a key adaptive trait that can help us understand how plants respond to a changing climate from the molecular to landscape scale. Despite this, acquisition of bud break data is currently constrained by cost, scale, and a lack of information at the plant scale on the environmental...

Invisibility: Environmental Migration Governance in a Changing Climate

Creator:: Abel, Kali M.
Abstract:: Climate change has the potential to accelerate many forms of human migration and mobility, yet almost all of the key migration outcomes of interest are determined predominantly by governance, or the norms, laws, and institutions involved in the coordination of human society. These outcomes include the decision whether or not...

Modeling the Environmental Protection Agency's level IV ecoregions within the Klamath Mountains of southern Oregon and northern California

Creator:: Zanger, Christopher
Abstract:: Ecoregions are regions of relative homogeneity with respect to specific ecosystem variables (Bailey 1976; Omernik 1995). There has been an increasing awareness that effective management of environmental resources must be undertaken with an ecosystem perspective (Omernik, 1995). Ecoregions serve as a spatial framework for assessing, managing, and monitoring ecosystems that...

The effects of stand thinning on soil erosion rates at Jim's Creek in the Willamette National Forest, Oregon

Creator:: McFadden, Andrew K.
Abstract:: Surface sediment transport is an important geomorphic process which can be significantly altered by management activities in forested ecosystems. Disturbance of the soil surface may result in increased sediment delivery to fish bearing streams and degradation of soil structure. Selective thinning and low impact yarding techniques were utilized in an...
