Landscape models for elk distribution developed at Starkey Experimental Forest and Range from 1993-1995 were tested on another landscape during 2003-2005 at Sled Springs Wildlife Demonstration Area. Using location data obtained from 23 wild elk captured and fitted with GPS telemetry collars, 8 spatial resource selection function models representing 8...
Reintroduction programs are increasingly being used to save animals from extinction and aid in their recovery. The California Condor (Gymnogyps californianus), one of the most endangered birds in the world, is a remarkable example of how reintroduction programs can help rapidly increase a species' population numbers and range following a...
Prescribed burning is increasingly being used as a management tool to reduce potential fuels on the forest floor and promote stand vigor through removal of dense, crowded vegetation. Because fire affects both the standing vegetation and the amount of downed wood in the ecosystem, it is imperative to examine how...
Detailed phytosociological and physical data were gathered from six grass-fern balds in the Oregon Coast Range, Monmouth Peak, Grass Mountain, Prairie Peak, Roman Nose Mountain, Tyee Mountain, and Saddle Mountain. Panchromatic and color infrared air photography guided sampling within individual balds. The resultant floristic data was manipulated by a Braun-Blanquet...
Surface and subsurface mapping are combined to determine the
geologic history along the San Gabriel fault near the town of Castaic.
Palomas Gneiss, Whitaker Granodiorite, and Pelona Schist are basement
terranes encountered in the subsurface. West of the San
Gabriel fault, basement is unconformably overlain by marine middle
to late...
The Santa Barbara-Montecito and Goleta basins are structurally
continuous fault-controlled Pleistocene basins containing
up to 3000 feet (925 m) of marine Pleistocene Santa Barbara Formation
which were deposited on previously deformed Sisquoc and older
strata. Structures subcropping against the unconformity at the
base of the Santa Barbara Formation show that...
The Grant Range, in east-central Nevada, is a
north-east trending range bounded on the west by a
west-dipping normal fault system. Rocks within the range
record a complex polyphase Mesozoic ductile
compressional and Cenozoic brittle extensional
deformational history. The northwestern Grant Range
exposes deformed, regionally metamorphosed and
unmetamorphosed, Cambrian to...
Headwater streams are an integral part of the ecological health of the greater stream network as they provide valuable biological habitat, provide upwards to 95% of total in channel flow, while providing downstream reaches with important constituents such as sediment and woody debris. Small headwater streams are particularly susceptible to...
Hatcheries are used to produce salmon to augment the number of fish available for harvest, and to supplement wild populations that may be threatened with extinction. Although traditional hatchery rearing methods can produce many fish, they can pose risk to wild populations because they tend to produce salmon with lower...

Sea-salt aerosols (SSA) impact the cycling of nutrients within coastal soils, including the mobility of dissolved organic carbon (DOC) and ammonium, denitrification, and litter decomposition. These aerosols are formed during tumultuous weather in the open ocean and are transported and deposited inland by wind. Soils closer to the ocean are...
In recent years, many studies have focused on the molecular and biochemical mechanisms regulating the development of wine grapes. The course of grape berry development is directed by genetic design and is mediated by phytohormones, which regulate grape berry growth and development by orchestrating a complex network of interacting genes,...
The growth of Brettanomyces bruxellensis is a major cause of wine spoilage due tothe production of the volatile phenols 4-ethylphenol (4-EP) and 4-ethylguaiacol (4-EG), derivatives of p-coumaric acid and ferulic acid. During the winemaking process,some microorganisms can impact the concentration of the 4-EP precursors pcoumaricand coutaric acid (tartaric acid-esterified p-coumaric...
In this Dissertation, the mechanism and stereomechanics of complex organocatalysis and reaction processes are disclosed. The technologies and protocols currently being developed and utilized to efficiently investigate these systems using theory are highlighted.
A detailed computational study of peptide-catalyzed acylations is disclosed. In particular, the magnitude of all possible non-bonding...
Currently, fungicide applications are the predominant method of control for the cool weather pathogen Microdochium patch (Microdochium nivale). Increasing pesticide restrictions have generated concern regarding management of Microdochium patch. Three separate field trials exploring non-traditional fungicides were conducted between 2013 and 2015 on an annual bluegrass (Poa annua L.) sand-based...
Edible coatings controlling preservative migration from
surface to food bulk could inhibit surface microbial growth
which is often the main cause of spoilage for many food
products. In this project we focused our attention upon
methylcellulose, hydroxypropyl methylcellulose, and chitosan as
the structural component for such edible films. These films...
Biological invasions pose one of the greatest threats to global biodiversity, but many naturalized invaders coexist with the native community. Community ecology theory provides a framework for understanding the mechanisms by which invaders might coexist with native species or exclude them from the community, thus informing management practices to maximize...
This research examines two questions: 1) What stories do Christian teacher educators tell about their own White racial identity development? and 2) Is there an impact of studying White racial identity development on the praxis of Christian teacher educators? If so, in what ways? The researcher began the project with...

Stream temperature is a water quality parameter that directly influences
the quality of aquatic habitat, particularly for cold-water species such as Pacific
salmonids. Forest harvesting adjacent to a stream can increase the amount of
solar radiation the stream receives, which can elevate stream temperatures
and impair aquatic habitat. Oregon Forest...
