Spatiotemporal Assessment of Crop Histories in the Pacific Northwest

Creator:: Kumbhakar, Ishika G.
Abstract:: The cultivated potato (Solanum tuberosum) is one of the most important food crops in the United States, as well as globally. As demand rises, growers in the Pacific Northwest are revisiting their crop management strategies to determine whether there are additional ways to enhance crop productivity while managing plant and...

Predicting the stability, equilibrium response, and nonequilibrium dynamics of ecological systems

Creator:: Hosack, Geoffrey R.
Abstract:: In this dissertation, new theory and its applications are developed to predict three properties of complex ecological communities: stability, equilibrium response, and non-equilibrium dynamics. First, a graph-theoretic analysis identifies the interconnections in a complex ecosystem that promote or diminish stability (Chapter 2). The hierarchy of interactions that influences stability and...

Developing a plan for the national coordination of geospatial technology education : a community college perspective

Creator:: Sullivan, Deidre E.
Abstract:: Geospatial technology is a rapidly growing and changing field. The term geospatial technology (GST) refers to geographical information systems (GIS), global positioning systems (GPS), and remote sensing (RS), all emerging technologies that assist the user in the collection, analysis, and interpretation of spatial data. The speed at which new fields...

Landsat-based monitoring of annual wetland change in the main-stem Willamette River floodplain of Oregon, USA from 1972 to 2012

Creator:: Fickas, Kate C.
Abstract:: Despite holding substantial ecological value, wetlands in the United States have experienced a significant decline in both area and function over the past century with the majority of freshwater wetland loss attributed to agricultural conversion. Agriculture is the second largest industry in the State of Oregon and the State places...

Post-harvest establishment influences ANPP, soil C and DOC export in complex mountainous terrain

Creator:: Peterson, Fox S.
Abstract:: The link between aboveground net primary productivity (ANPP) and resource gradients generated by complex terrain (solar radiation, nutrients, and moisture) has been established in the literature. Belowground ecosystem stocks and functions, such as soil organic carbon (SOC), dissolved organic carbon (DOC), and belowground productivity have also been related to the...

Effects of spatial scale and heterogeneity on avian occupancy dynamics and population trends in forested mountain landscapes

Creator:: Frey, Sarah J. K.
Abstract:: Population trends and patterns in species distributions are the major currencies used to examine responses by biodiversity to changing environments. Effective conservation recommendations require that models of both distribution dynamics and population trends accurately reflect reality. However, identification of the appropriate temporal and spatial scales of animal response, and then...

Social, Ecological, and Economic Outcomes Associated with Stewardship Forestry in the Siuslaw Watershed

Creator:: Colón–Almodóvar, Yamilette M.
Abstract:: In 1994, with the approval of the Northwest Forest Plan, the livelihood of individuals in the surrounding communities of the Siuslaw National Forest and Siuslaw Watershed were further impacted by already diminished traditional timber practices. In 2003, the United States Forest Service developed an innovative program, stewardship contracting, aimed at...

A geospatial data catalog and metadata management tools for the U.S. Environmental Protection Agency’s Western Ecology Division

Creator:: Bradford, David L.
Abstract:: The EPA’s Western Ecology Division (WED) had been accumulating geographic information system (GIS) data files for up to 20 years. There was no index or catalog for these files; locating data became more difficult over time. More that 4 Tb of data existed on numerous disk volumes in hundreds of...

Lava Flow Lobation and Margin Analysis

Creator:: Peckyno, Robert S.
Abstract:: Comparative investigations based on volcanic morphology suffer from the lack of a large terrestrial baseline for comparison. To fill this gap, the Lava Flow Morphology Database (LAMDA) was proposed as a GIS based central clearinghouse for remote and field investigations of volcanic morphology. This study presents an analysis of LAMDA’S...

Evaluation of Deforestation in the Rio Platano Biosphere Reserve, Honduras

Creator:: Wade, Michael C.
Abstract:: Satellite imagery has been a useful tool in monitoring land cover changes, including changes within protected areas. In the 1980’s and 1990’s Honduras created over 100 protected areas, yet few resources have been dedicated to their management. This study used Landsat satellite imagery to evaluate deforestation in the Río Plátano...
