The influence of prescribed fire on the rare endemic plant Delphinium pavonaceum (Peacock larkspur)

Creator:: McKernan, Brie-Anne
Abstract:: In the wetland prairie of William L. Finley National Wildlife Refuge (FNWR) in western Oregon, we investigated the response of Delphinium pavonaceum Ewan (peacock larkspur, Ranunculaceae), an endangered perennial forb, to four unreplicated dormant season fire regimes of 0, 2, 4, or 10 fires that were applied over a 12-year...

Floodplain vegetation following over 80 years of intensive land use and de-watering : Lower Owens River, California

Creator:: Risso, Derek A.
Abstract:: Riparian areas in the arid western United States are critical ecosystems that have been severely degraded by a variety of land and water uses over the last 100 years. In this study, the composition and structure of floodplain vegetation along the Lower Owens River in eastern California was quantitatively described...

Indirect effects of fishing on predators and their prey

Creator:: Stallings, Christopher Derek
Abstract:: Predators are fundamentally important for regulating and driving prey population dynamics as well as structuring ecological communities. Over-exploitation of marine resources has caused dramatic depletions of predatory fish species and shifts in marine community composition, with attendant declines in productivity and diversity of marine ecosystems. Despite the important ramifications of...

Optical Characterization of Transparent Conductive Thin Films

Creator:: Tucker, Derek A.
Abstract:: The optical characterization of transparent conductive thin films is demonstrated. The basics of transparency and conductivity, as they relate to transparent conductor research, are explained. A functional model of the reflectance and transmittance of a sample film, including interference fringes, is derived from the Fresnel electric field amplitude coefficients. The...

Residue management and yield characteristics of fine fescue seed crops

Creator:: Schumacher, Derek David
Abstract:: Chewings fescue [Festuca rubra L. subsp. fallax (Thuill.) Nyman] is a desired turfgrass with dense sod forming capabilities and superior shade tolerance. Thermal residue management (open-field burning) has traditionally been used to remove post-harvest residue and maintain seed yield over the life of the stand. However, alternative non-thermal residue management...

The benefits of diversified agricultural systems among Maya Mopan farmers in southern Belize

Creator:: Hofbauer, Derek M.
Abstract:: Maya Mopan farmers in southern Belize face socio-economic hardships, persisting environmental constraints, and an unfavorable political climate that has prevented land tenure stability on reservation lands. This thesis describes the agricultural practices of a group of Mopan farmers and examines farm-site diversification and its relationship to ecological knowledge, out-migration, agricultural...

A possible sequence of events for the generalized glacial-interglacial cycle

Creator:: Peacock, Synte, Lane, Emily, and Restrepo, Juan M.
Abstract:: There is not yet widespread agreement as to the underlying cause of the 80– 100 ppmv roughly 100-kyr-duration glacial-interglacial cycles in atmospheric pCO2. Most of the mechanisms which have been proposed to account for the observed pCO2 variations appear to in some way violate interpretations of paleo proxy data. The...

Opportunities and limitations for community forest enterprises : case of TIP Muebles, Oaxaca, Mexico.

Creator:: Villavicencio Valdez, Gabriela Valeria
Abstract:: The fact that 80 percent of Mexican forestlands are under common ownership impacts the competitiveness of the forest products industry and forest sustainability. Community forest enterprises (CFE) are a heterogeneous group of forest industries managed by indigenous and local communities for livelihood and profit. Many CFEs face inner competitiveness problems,...

From risk to resiliency : academic persistence in Mexican-American high school English as a Second Language students

Creator:: Temes, Carla A.
Abstract:: Five student-researchers and the author engaged in a continually-evolving, student-driven qualitative research study. Despite significant disadvantages, including navigating a. foreign culture without speaking the language, these invulnerable learners succeeded. Ultimately of greatest interest to the six were an analysis of their collective knowledge and experiences, and their individual transformation over...
