Evaluation Of 1-D And 2-D Hydraulic Models For Designing And Assessing Fullspan Stream Crossings, Alyssa Sachiko Virgil

Cal Poly Humboldt theses and projects

This project compared design decisions and hydraulic analyses of full-span stream crossings using one- and two-dimensional (1-D and 2-D) hydraulic models. The project was initiated by the California Department of Transportation’s interest in moving from 1-D to 2-D hydraulic modeling and by the Federal Highways Administration’s support for adopting SRH-2D (Sedimentation and River Hydraulics-2D developed by the US Bureau of Reclamation) in Aquaveo, LLC’s Surface-water Modeling System as their standard design model. Two-dimensional hydraulic models calculate more detailed water depths and velocities than 1-D models, which can better identify fish passage conditions, areas of potential scour or deposition, and aquatic …

Cuteness As A Prime To Enhance Emotional Recognition, Andrew Diaz

Cal Poly Humboldt theses and projects

The ability to recognize emotional expressions has important implications for survival and cooperation. Failing to recognize emotions indicative of some form of threat (anger, fear, disgust) may be particularly costly given these emotional expressions communicate a potential source of danger in the environment. Previous studies have shown that people tend to recognize threatening emotions faster and more accurately than non-threatening emotions. Infantile characteristics (kindchenschema) readily capture the attention of adults and have been shown to influence a variety of behaviors associated with caretaking; viewing cute stimuli increases behavioral carefulness on various visual and motor tasks. The current study …

Recolonization Potential For Coho Salmon (Oncorhynchus Kisutch) In Tributaries To The Klamath River After Dam Removal, Max M. Ramos

Cal Poly Humboldt theses and projects

Removal of four major dams on the Klamath River is scheduled to begin in 2023, restoring access to greater than 50 km of historic mainstem habitat for coho salmon. However, mainstem habitat may not be suitable for juvenile coho salmon due to elevated water temperatures and high concentrations of infectious myxospores in the summer and fast water velocities in the winter. Small, cooler tributaries can provide essential habitat for escape from deleterious conditions in the mainstem Klamath River. I used temperature and other physical features of six tributaries to the Klamath River above Iron Gate Dam to assess their capacity …

Corporate Purpose In A Populist Era, Stephen M. Bainbridge

Nebraska Law Review

In the wake of the 2016 U.S. presidential election and similar developments in parts of Europe, commentators widely acknowledged the rise of populist movements on both the right and left of the political spectrum that were deeply suspicious of big business. This development potentially has important implications for the law and practice of corporate purpose.

Left-of-center corporate social responsibility campaigners have long advocated the use of “boycotts, shareholder activism, negative publicity, and so on” to pressure corporate managers to act in ways those campaigners deem socially responsible. Right-of-center populists could use the same tactics to induce corporate directors to make …

Shifting Sands: Social Cues Influence The Long-Term Dynamics Of Snowy Plover Distribution, Jeremy John Pohlman Mr

Cal Poly Humboldt theses and projects

Understanding the social and physical factors that influence the temporal and spatial distribution of a species is imperative for successful management. The Western Snowy Plover (Charadrius nivosus nivosus) selects for wide-open stretches of beach; yet within large expanses of ideal habitat, plover populations tend to be aggregated. Recent evidence suggests plovers may prioritize social information over ideal physical factors alone when selecting breeding locations. I analyzed data collected on an individually marked population of Snowy Plovers in Humboldt County, California from 2001 to 2018 to evaluate the influence of physical (beach width) and social (presence of conspecifics) landscape …

Mand Training And Prompt Fading: Teaching Yes-No Manding, Jessica M. Kelly

Cal Poly Humboldt theses and projects

Language is a collection of verbal skills which allows the speaker to have some control over how others interact with them. Saying the words “yes” and “no” are fundamental language abilities; The words impact the speaker’s environment by communicating acceptance or rejection of stimuli and experiences. Caregivers, teachers, and friends may have to make choices for an individual who cannot respond to yes-no questions. This skill deficit deprives the individual of autonomy and can lead to challenging behaviors occurring in place of clear communication. Applied Behavior Analysis offers techniques to teach language skills such as saying “yes” and “no” in …

Micronutrient Supplementation In Relation To Hair Loss Syndrome In California Mule Deer, Max W. Marquez

Cal Poly Humboldt theses and projects

The Jawbone deer herd has been monitored on their wintering grounds since the 1950s and recently began decreasing over the last several years. The decline prompted an investigation into the reasons why. Coinciding with the population decline is the appearance of hair loss syndrome and two species of exotic lice. In order to evaluate the effects of hair loss syndrome and the influence of exotic lice infestation, 38 wild does from the herd were used in a modified-before-after-control-impact study. Does were treated with micronutrients selenium and copper via boluses in winter (December 2013-January 2014). Selenium treatment, at a dose of …

Comparing Environmental Dna And Traditional Monitoring Approaches To Assess The Abundance Of Outmigrating Coho Salmon (Oncorhynchus Kisutch) In California Coastal Streams, Emerson Alan Kanawi

Cal Poly Humboldt theses and projects

Environmental DNA (eDNA) has the potential to dramatically increase the information available to managers regarding species distribution and abundance. Collection of reliable survey information on fish abundance is essential to monitor population trends and restoration efforts for endangered and threatened species. In Northern California, coho salmon are a federally listed species and a focus of ongoing monitoring programs and restoration projects. I examined the feasibility of using eDNA to supplement, or replace, traditional outmigrating juvenile coho salmon monitoring approaches currently used at two existing coho salmon life-cycle monitoring stations. Over the spring of 2018 and spring of 2019, I collected …

Ain't No Love In The Heart Of The Mountains: Hip-Hop, Exclusion, And The White Wilderness, Leonard Alexander Henderson

Cal Poly Humboldt theses and projects

The expectations of normative behavior in outdoor recreation are often taken for granted and naturalized within dominant cultural narratives about human/nature interactions. In particular, expectations of silence and an absence of evidence of humans and human sounds (anthrophony), are grounded within an understanding of nature and a wilderness/urban paradigm framed by whiteness. Hip-Hop provides an interesting point of analysis for thinking about the binary opposition of wilderness and urbanness. The intersection of Hip-Hop and wilderness is also the starting point for my research. This research aims to speak to just a few ways that white and masculine social norms in …

Age-Specific And Species-Specific Tree Response To Seasonal Drought In Tropical Dry Forests, Emily A. Santos

Cal Poly Humboldt theses and projects

Millions of people live in or depend on ecoregions dominated by Tropical Dry Forests (TDFs), but due to their high accessibility, convenient topography and mild climate conditions their distribution is fragmented with less than 10% of their original extent remaining in many countries. Despite the vast ecosystem services provided by TDFs, including vital water resources in water limited environments, ecohydrological research in this biome has been limited to a small number of short-term investigations. Similar to worldwide trends, the TDF surrounding Bahía de Caráquez (Bahía), Ecuador, has been severely deforested over the past 400 years. The land use history in …

The Rattle Call: A Female-Specific Vocalization In Steller's Jays, Kachina L. Rowland

Cal Poly Humboldt theses and projects

While the elaborate songs of male passerines are well documented for their role in intrasexual resource competition and mate attraction, vocalizations used in female competition are poorly understood. Research has suggested that the female-specific rattle call of Steller’s jays (Cyanocitta stelleri) is used in competition for access to a territory and mate. I describe structural properties of the rattle call, and compare life history traits of individual females to rattle call occurrence. I used two rates to quantify rattle call occurrence from 20 females: rattles per observation period (RPO), and proportion of observations with a rattle call (POR) …
