Habitat Selection And Habitat Use Of Gray Foxes (Urocyon Cinereoargenteus) On Trespass Cannabis Grows., Haley-Marie R. Jones
Habitat Selection And Habitat Use Of Gray Foxes (Urocyon Cinereoargenteus) On Trespass Cannabis Grows., Haley-Marie R. Jones
Cal Poly Humboldt theses and projects
Trespass cannabis grow sites, otherwise known as illegal cultivation sites on public lands, are extremely hazardous to the environment and can severely impact wildlife movement and behavior. Trespass grow sites are dangerous to wildlife as they negatively impact the quality of habitat and wildlife behavior through habitat modification, pesticide use, discarding of trash, and poaching on national forests. I researched gray fox habitat selection and habitat use at six different grow sites in the Klamath National Forest and Shasta-Trinity National Forest in northwestern California. I deployed GPS collars on three gray foxes at two of those grow sites and three …
Western Gulls’ (Larus Occidentalis) Reproductive And Behavioral Responses To Human Disturbance, Lilamarie 'Asta Bowen
Western Gulls’ (Larus Occidentalis) Reproductive And Behavioral Responses To Human Disturbance, Lilamarie 'Asta Bowen
Cal Poly Humboldt theses and projects
Human disturbances can negatively affect wildlife by causing stress, altering behavior, or even impacting populations through changes in survival or productivity. Colonial-nesting seabirds are of particular concern due to population declines and their gregarious and conspicuous nature, which may attract human visitors. However, the effects of nearby human activities, though frequently negative, could be neutral or even positive through phenomena like habituation to human activities or subsidization by human-supplied food sources. In this observational study, I evaluated relative support for three hypotheses which may explain how Western Gulls are impacted by human activity: disturbance, habituation, and subsidization. I investigated this …
Activity Patterns Of The Del Norte Salamander (Plethodon Elongatus): Monitoring Plethodontid Behavior Using Pit Tag Surveys, Sabrina Horrack
Activity Patterns Of The Del Norte Salamander (Plethodon Elongatus): Monitoring Plethodontid Behavior Using Pit Tag Surveys, Sabrina Horrack
Cal Poly Humboldt theses and projects
Semi-fossorial plethodontid salamanders exhibit behavioral plasticity to avoid desiccation, retreating underground to shelter from adverse conditions such as low precipitation and high temperatures. In this study, I used passive integrated transponder (PIT) tag surveys to monitor this behavior in the Del Norte salamander (Plethodon elongatus), a small plethodontid native to northwestern California and southwestern Oregon. Within its range, a climatic gradient exists in which coastal areas experience milder temperatures and high precipitation, while inland areas tend to have colder winters, hotter summers, and lower precipitation. By monitoring the activity patterns of this species in inland and coastal areas, …
Sustainable Transportation For Hsu Stakeholders: Looking Into Access And Behavior, Aneika J. Perez
Sustainable Transportation For Hsu Stakeholders: Looking Into Access And Behavior, Aneika J. Perez
Cal Poly Humboldt theses and projects
Aneika Jasmine Perez
Safe and affordable transportation to and from campus are not available to many members of the HSU community. This research seeks to understand how members of the campus community can access forms of transportation without relying on private automobiles. A critical component of this research is to understand specific ways in which members of the campus community can access sustainable forms of transportation without relying on private automobiles.
This research draws primarily on Icek Ajzen’s (1991) Theory of Planned Behavior framework, to determine that choice of travel mode is based on decisions that are affected by …
An Ecomorphological Analysis Of Locomotion In Larvae And Neotenes Of Two Salamander Species: Dicamptodon Tenebrosus (Stream-Type) And Ambystoma Gracile (Pond-Type), Ethan Hardister Snee
An Ecomorphological Analysis Of Locomotion In Larvae And Neotenes Of Two Salamander Species: Dicamptodon Tenebrosus (Stream-Type) And Ambystoma Gracile (Pond-Type), Ethan Hardister Snee
Cal Poly Humboldt theses and projects
Morphology is the physical expression of a species’ evolutionary history and adaptation to its environment and as such is tied to ecology. Salamander larvae have historically been separated into "pond-type" and "stream-type" groups based on their morphology, however no studies have been performed quantifying the relationship between morphology and ecology. In this study I utilized in-situ behavioral observations, morphological measurements, and in-lab performance tests of Dicamptodon tenebrosus (stream-type) and Ambystoma gracile (pond-type) to examine the relationship between salamander larval morphology and ecology. In the field, behavior was video recorded during nighttime surveys; afterwards animals were captured and limb measurements were …

School-To-Prison-Pipeline: The Factors That Cause It, And How We Can Prevent It, Alison L. Wittig
School-To-Prison-Pipeline: The Factors That Cause It, And How We Can Prevent It, Alison L. Wittig
Cal Poly Humboldt theses and projects
The “School-to-Prison pipeline” is an ongoing challenge and trend in the public school system in America due to inequity in the educational system, discriminatory policies towards students and families of color, and a lack of resources aimed at supporting at-risk youth and the economically disadvantaged within the community. Public schools have made continued progress in shifting their disciplinary policies away from punitive, “zero tolerance” models and towards positive behavioral interventions, but there continues to be a disproportionate number of students ending up in the school-to-prison-pipeline from economically disadvantaged communities and homes. Lawmakers continue to create policies in an effort to …
