Spatial Ecology Of Mountain Lions Throughout Their Distribution In California, Kyle D. Dougherty

School of Natural Resources: Dissertations, Theses, and Student Research

Mountain lions (Puma concolor) have been studied extensively throughout their wide geographic distribution in the Western Hemisphere, but most research has been conducted at relatively small spatial scales. We used GPS telemetry data contributed by researchers in 16 study areas throughout California to advance understanding of mountain lion spatial ecology. First, we investigated multi-scale resource selection of mountain lions relative to spatially varying risk of intentional human-caused mortality associated with livestock depredation management. We show that individuals that proactively avoided mortality risk when selecting home ranges were able to relax their avoidance of risk when making resource selection …

Assessing The Use Of Regenerative Agriculture In California Almonds As Climate Change Resilience, Skyler M. Seamons

Master's Projects and Capstones

The agriculture sector is responsible for 10% of the United States’ greenhouse gas emissions. In turn, anthropogenic climate change threatens crops. With its Mediterranean climate, California is the country’s largest agricultural-producing state. Many California crops are at risk due to increasing temperatures and changed precipitation patterns. This paper investigates regenerative farming techniques as a tool to protect California crops from a changing climate. Almonds are used as a case study to analyze the soil management practices, finances, and policies underlying regenerative agriculture in California. A literature review and comparative analysis are used to compare regenerative and conventional soil management practices …

Screening For Food And Nutrition Insecurity In The Healthcare Setting: A Cross-Sectional Survey Of Non-Medicaid Insured Adults In An Integrated Healthcare Delivery System, Carmen Byker Shanks, Nancy P Gordon

Student and Faculty Publications

OBJECTIVES: Healthcare screening identifies factors that impact patient health and well-being. Hunger as a Vital Sign (HVS) is widely applied as a screening tool to assess food security. However, there are no common practice screening questions to identify patients who are nutrition insecure or acquire free food from community-based organizations. This study used self-reported survey data from a non-Medicaid insured adult population approximately one year after the start of the COVID-19 pandemic (2021). The survey examined the extent to which the HVS measure might have under-estimated population-level food insecurity and/or nutrition insecurity, as well as under-identified food and nutrition insecurity …

A Brief But Comprehensive Three-Item Social Connectedness Screener For Use In Social Risk Assessment Tools, Nancy P Gordon, Matthiew C Stiefel

Student and Faculty Publications

BACKGROUND: The 2014 IOM report "Capturing Social and Behavioral Domains and Measures in Electronic Health Records" described three subdomains of social relationships that affect patient health and well-being. However, most social risk screeners currently assess only one subdomain, frequency of social connections. We are proposing a three-item Brief Social Connectedness (SC) screener that additionally assesses risks in social/emotional support and loneliness/social isolation subdomains.

METHODS: For this cross-sectional study, we used data from a 2021 Kaiser Permanente Northern California (KPNC) social risk survey for 2244 members ages 35-85 years. The survey included three validated questions that covered the SC subdomains (frequencies …

Determining The Quality And Quantity Of California Sitka Spruce (Picea Sitchensis) On Private Commercial Timberland For Use In Domestic Acoustic Steel-String Guitars, Ryan Eugene Cooper

Cal Poly Humboldt Capstone Honor Roll

Development of additional revenue streams for timber products with relatively low profitability is an important step in securing future economic success for the forestry sector in Humboldt county. Utilization of California Sitka spruce (Picea sitchensis) for use in domestic acoustic steel-string guitar manufacturing may provide exactly that. Determining the quality and quantity of California Sitka spruce is the logical first step in achieving this.

Quality was determined from tree core samples gathered at sites on Green Diamond Resource Company’s (GDRco) California timberlands and the Arcata Community Forest (ACF) with high basal area of Sitka spruce. Rings Per Inch …

Vascular Floristic Study Of The Piute Mountains, Kern County, California, Courtney Matzke

CGU Theses & Dissertations

This study describes the vascular flora of the Piute Mountains, located at the southern terminus of the Sierra Nevada in Kern County, California. The study area covers ca. 543 square km (210 square mi), with elevations ranging from 777 m (2,550 ft) to 2,562 m (8,406 ft) at Piute Peak. Though situated in the Sierra Nevada ecoregion, the Piute Mountains lie near the Mojave Desert, Central Valley, and southern California mountains, resulting in a highly diverse, unique flora with plant taxa from each of these regions co-occurring. The study area encompasses varied topography with an assortment of geologic features including …
