A Picture Worth A Thousand Words: Factors Influencing Disability Accommodations, Alicia E. Martin Jan 2023

A Picture Worth A Thousand Words: Factors Influencing Disability Accommodations, Alicia E. Martin

Cal Poly Humboldt theses and projects

Because not all disabilities look the same it is difficult to label a person with disabilities just by looking at them. Given that our knowledge, attitudes, and perceptions impact how we interpret our world and our willingness to act, people, including professors, may be biased toward providing accommodations for those with easily recognizable disabilities and biased against those with non-recognizable disabilities, and this may impact the disabled person’s ability to learn. This thesis aims to address whether professors’ disability-related attitudes, perceptions of accommodation reasonableness, and willingness to provide accommodations differ when the disability is recognizable (student is pictured in a …


Comparison Of Standard And Environmental Dna Methods For Estimating Chinook Salmon Smolt Abundance In The Klamath River, California, Doyle Joseph Coyne Jan 2021

Comparison Of Standard And Environmental Dna Methods For Estimating Chinook Salmon Smolt Abundance In The Klamath River, California, Doyle Joseph Coyne

Cal Poly Humboldt theses and projects

Evaluating abundance of juvenile salmonids is critical to conservation and management. Current abundance estimation involves use of rotary screw traps and mark-recapture studies. Use of environmental DNA (eDNA) in water samples offers a noninvasive and less expensive approach that may potentially improve or eventually replace traditional monitoring. Here I evaluate the utility of eDNA to predict weekly abundance estimates of outmigrating Chinook salmon (Oncorhynchus tshawytscha) smolts in the Klamath River, California. A total of 15 water samples were collected per week over the 17-week smolt outmigration in both 2019 and 2020. Chinook salmon eDNA concentration in each water …


Western Snowy Plover Nest Survival In Humboldt County, California, Katelyn M. Raby Jan 2018

Western Snowy Plover Nest Survival In Humboldt County, California, Katelyn M. Raby

Cal Poly Humboldt theses and projects

Productivity measures, such as nest survival, are often used to indirectly assess habitat quality and guide targeted management practices for the conservation of threatened and endangered species. The coastal population of the Western Snowy Plover (Charadrius nivosus nivosus) is listed as threatened due to three limiting factors: human disturbance, loss and degradation of habitat as a result of invasive plants, and increasing predator populations. I examined the relative influence of these three limiting factors on nest survival, using data from 2004 to 2017 at eight sites in Humboldt County, California. I assigned nests (n = 610) to three …
