Comparison of transect call-point and acoustic sampling of white-headed woodpeckers (Dryobates albolarvatus) within mixed-conifer and ponderosa pine (Pinus ponderosa) forest types

Creator:: Gaylord, Marie A.
Abstract:: We used occupancy modeling to compare the detection probabilities of white-headed woodpeckers using transect call-point versus ARU surveys. We then used the estimated detection probability for each survey method to evaluate the number of surveys needed to infer white-headed woodpeckers absence under different levels of certainty.

An Evaluation of Wallowa Stock Hatchery Residual Oncorhynchus mykiss Monitoring and Management Strategies

Creator:: Smith, Jorden D.
Abstract:: Hatchery O. mykiss that fail to emigrate to the ocean, referred to as residuals, present an ecological and genetic risk to naturally-produced species through resource competition, predation, and spawning interactions. The Lower Snake River Compensation Plan’s Wallowa stock steelhead program in northeast Oregon has established methods of reducing and quantifying...

Spatial and Temporal Patterns of Detection of Native Lampreys in Central Valley California: A Starting Point

Creator:: Parker, Christina M.
Abstract:: Native lamprey species in the Central Valley of California serve important ecological roles in rivers and tributaries and face similar conservation challenges as salmonids. Concerns of declining lamprey populations have led to collaboration of tribes, local, state, and federal agencies to increase understanding of ecology and life history. Pacific Lamprey...

Refinement and Evaluation of the Forest Management Plan for the Waiākea Timber Management Area

Creator:: Quiocho, Kennon
Abstract:: Hawai’i’s economy is 2 dimensional, relying both on agricultural products and tourism. In order for the state to have a more sustainable economy it’s going to need multiple sources of revenues and not rely primarily on one. Currently there is no successful model of timber harvesting in Hawaii. Developing a...

Eugene Residents Risk Perceptions of Water Scarcity

Creator:: Leitermann, Lily
Abstract:: Potential water scarcity and drought conditions are predicted in and around Eugene, Oregon due to decreased snowpack and subsequent decreased snowmelt in the Western Cascade Mountains. This phenomenon was triggered by a long-term trend of warmer winters scientifically linked to global climate change patterns (Dalton et al. 2013). Numerous stakeholders,...

Sampling plan to determine mercury (Hg) contamination in the Nanay river basin

Creator:: Rodriguez, Tiffany
Abstract:: Propose a sampling plan to determine Hg contamination in the Nanay river basin. The sampling plan is for a feasibility pilot, to investigate whether it is possible to safely collect samples for Hg analyses. Future studies will build on these initial results.

Grassland Restoration and Climate Change: Altar Valley, Arizona Case Study

Creator:: Gondor, Anne
Abstract:: The Altar Valley is an important working landscape that supports biodiversity and vulnerable species in Pima County, Arizona (Huckelberry 2000). This semi-desert grassland, alluvial valley and 713,807-acre watershed composed of 39 subbasins serves as an aquifer to a portion of southwestern Tucson. This region of Southern Arizona has been identified...

Between Wild and Cultivated Places: Natural Resource Planning on a Small Farm in the Chesapeake Bay Watershed

Creator:: Cliff, Eliza H.
Abstract:: To meet the challenges of climate change and make progress on lagging large-scale sustainability and watershed goals requires an integrated social-ecological approach to natural resource planning on the ground-level. This case study of a small equestrian farm in the Chesapeake Bay watershed incorporates theory with practice, by adding interviews focused...
