Unoccupied aircraft systems in forest monitoring applications

Creator:: Barker, Matthew I.
Abstract:: In recent years, unoccupied aircraft systems (UAS) have become increasingly affordable and straightforward to incorporate in monitoring applications of forested ecosystems. This shift has facilitated interest in using these tools to monitor aspects of forest ecosystems including vegetation health, forest structure and composition, and potential habitat provided by these systems....
Resource Type:: Dissertation

The Public’s Perception of Fire Prevention and Communication in the Tonto National Forest

Creator:: Lindley, David
Abstract:: As the frequency and intensity of wildfires continue to occur in the West, so does the need for measures intended to improve firefighter safety; public safety; and the protection of property, resources, and wildlife. Furthermore, as human activity in the expanding Wildland Urban Interface increases, so does the need for...
Resource Type:: Capstone Project

Interactions of Hydrological Processes and Riparian Zone Function During Seasonal Ceased Flow Regimes Within an Intermittent Stream Basin of the Oak Creek Watershed, Oregon, USA

Creator:: Colter, Nicholas R.
Abstract:: Riparian zone conservation is vital as species’ ability to adapt to a changing climate and pressure from land use is constantly tested. The unique microclimates of riparian zones offer cooler temperatures and resourceful habitats for aquatic and terrestrial organisms. This is essential during seasonal ceased flow regimes when water availability...
Resource Type:: Masters Thesis

Plant Species Diversity and Pasture Productivity of a High-input Dairy Pastureland System and a Low-input Sheep Pastureland System in Western Oregon, USA

Creator:: Anderson, Jordan D.
Abstract:: The sustainable use of natural resources, including the goods and services provided by pasturelands and rangelands, is of growing importance due to climatic uncertainty and population growth. Maintaining high productivity in livestock operations is necessary as land availability diminishes and global populations rise. The potential negative impacts to the environment...

An Examination of Gender and Racial/Ethnic Social Identities in Marine, Aquatic, and Fisheries Sciences

Creator:: King, Brittany D.
Abstract:: Despite growing efforts to recruit individuals from diverse backgrounds, natural resources fields, including marine aquatic and fisheries science, do not reflect the diversity of the United States. This dissertation utilized three studies to explore underrepresentation in marine, aquatic, and fisheries sciences by examining career influences, experiences, and perspectives at different...

Changes in Otolith Shape in Juvenile Chinook Salmon in Different Hatchery Rearing Conditions

Creator:: Ehrke, Melissa A.
Abstract:: The decline of the Chinook Salmon has been a mystery of recent years due to their decline. It has been speculated that wild origin salmon have more vigor and survivability than hatchery reared fish. This is thought to be due to rearing conditions, possibly affecting sensory organ development. The sensory...
Resource Type:: Undergraduate Thesis

Water intake structures as movement barriers for larval coastal giant salamanders (Dicamptodon tenebrosus)

Creator:: Eaton, Jordan E.
Abstract:: Dams, culverts, and water intake structures can impact the movement of aquatic and semi-aquatic species within streams and rivers. Datagaps exist regarding the impact of water intake structures on larval coastal giant salamanders (Dicamptodon tenebrosus) as these obstructions may produce a barrier to up and downstream movement. The Rock Creek...
Resource Type:: Honors College Thesis

An Investigation of Stage 0 Restoration in California and Oregon

Creator:: Schneider, Charles W.
Abstract:: Stream restoration efforts have increasingly started to focus on management actions that restore ecological function rather than focusing on species-specific habitat needs. Restoration practitioners in the Pacific Northwest have implemented numerous large-scale floodplain restoration projects to restore stream function at the valley scale. Some of these projects attempt to restore...
Resource Type:: Capstone Project

Deschutes River Salmonid Risk of Enteronecrosis in a Changing Climate

Creator:: Yusova, Sofiya
Abstract:: Ceratonova shasta is an obligate endoparasite of salmonid fish that is endemic to the Pacific Northwest of North America. The parasite has a complicated lifecycle with two distinct spore stages and two obligate hosts, a salmonid and a freshwater annelid. Myxospores released from infected salmonid hosts, infect Manayunkia occidentalis (freshwater...
Resource Type:: Masters Thesis

The Influence of Prey Predictability on the Foraging Behavior and Movement of Intertidal Predators

Creator:: Hennessey, Shannon M.
Abstract:: Fluctuations and spatial heterogeneity of habitat and resources is thought to underlie niche variation in animal populations, with intraspecific differences serving to produce or maintain population-, community-, or ecosystem-level patterns. Individual diet variation, defined as individual variation in food resource use within a population that is consistent over time, is...
