Return To Wolf Country: Exploring Rancher Knowledge Of Gray Wolves In Wallowa County, Oregon, Theodore Masters

Cal Poly Humboldt theses and projects

With the extirpation of gray wolves (Canis lupus) from the American West in the early 20^th Century, generations of ranchers have grazed livestock free from any threats by wolves. The absence of wolves from the western landscape has created an inter-generational gap in the experiential knowledge held by ranchers regarding how to manage livestock in wolf country. Using Wallowa County, Oregon, as a case study site, 18 cow-calf ranchers were interviewed to gain insights into the ways they generate and share knowledge of running livestock in landscapes shared with wolves. This study revealed the arrival of wolves …

Hormonal Medications And Partner Odor Preferences, Jeffrey Lee Frederick

Cal Poly Humboldt theses and projects

The ability to recognize kin through the olfactory sense has important survival and evolutionary implications when choosing mates. Failing to recognize kin when making a choice of whom to mate with can lead to an increase in detrimental genetic outcomes in offspring. Previous studies have indicated that normally ovulating heterosexual women and men prefer the body odor of those with dissimilar immune systems than those with similar immune systems. The use of hormonal contraceptives has shown a preference for similar immune system odors. The current study examines whether the use of hormonal medications predicts preference for body odor. Importantly, this …

Demographic Modeling Of Conservation Strategies For The Yosemite Toad (Anaxyrus Canorus), Corrina Rebecca Kamoroff

Cal Poly Humboldt theses and projects

The Yosemite toad (Anaxyrus canorus) is an anuran species endemic to the Sierra Nevada in California that, like many amphibians globally, has suffered population declines. The documented decline in A. canorus populations across their historic range highlights the need for an effective management strategy to protect the species from future extirpation. For this study, I estimated survival rates of A. canorus using a Cormack-Jolly-Seber model populated with data from a demographic study. I then used a female-only post-birth pulse stochastic Lefkovitch matrix model using vital rates I estimated and from the literature to simulate the effect of different …

Variation Of Larval Traits And Copper Tolerance In An Invasive Cryptic Species Complex (Watersipora: Bryozoa), Jason A. Lopiccolo

Cal Poly Humboldt theses and projects

Many factors contribute to the potential of a non-indigenous species to invade an area and become established. For bryozoan colonies of the cryptic species complex Watersipora (Neviani, 1896), this may include larval characteristics such as settlement rate, competency of metamorphosis, swimming duration, and the ability to tolerate copper, a common component in marine anti-fouling paints. Two common groups of Watersipora that occur along the California coast are W. subatra Clade A and an undescribed new species, Clade N. The goal of this research work was to discover what differences, if any, exist in the larval traits and copper tolerances of …

A Theater Of The Absurd: Economic Sanctions In The Emerging Age Of Multipolarity, Travis Cunha

Cal Poly Humboldt theses and projects

Economic Sanctions have been imposed on nations throughout the Global South during the post-World War Two era. This led to the “Sanctions Decade” of the 1990s which saw the most devastating impacts on civilians in nations like Haiti and Iraq. The 2014 Russian annexation of Crimea resulted in sanctions being imposed on Russia by the European Union (EU), and retaliatory counter-sanctions from Moscow ensued shortly after. The Russian counter-sanctions banned the importation of certain agricultural foodstuffs from the EU, and this ban had significant implications for farmers in the EU who were now unable to sell to the large Russian …

Geomorphic Evaluation Of The Goose Lake Fault And Fluvial Terraces At The Yager Creek–Van Duzen River Confluence, Northern Coastal California, Samuel E. Bold

Cal Poly Humboldt theses and projects

Upper-plate deformation in the southern Cascadia subduction zone is dynamic and complex, situated in the transition between northward translation to westward convergence. Rock uplift and incision rates characteristic of this dynamic region are preserved in suites of fluvial and marine terraces. Fluvial terraces at the Yager Creek–Van Duzen River confluence record fluvial incision rates, and are crosscut by the understudied Goose Lake fault, an upper plate structure. In this work, I use high resolution lidar imagery to map terrace surfaces, and use optically stimulated luminescence, radiocarbon, and Beryllium-10 geochronology to bracket terrace ages and calculate incision and slip rates. With …

A Characterization Of The Sandy Beach Surf Zone Fish Community And Their Ecology In Northern California And The Effects Of Marine Protected Areas, Katie B. Terhaar

Cal Poly Humboldt theses and projects

Historically written off as dull and homogenous, the dynamics of the sandy beach surf zone remains under studied world-wide. Northern California has been no exception to this global standard, as the sandy beach surf zone ecosystem in this region has yet to be characterized, and the effect of Marine Protected Areas (MPAs) on the fish and macroinvertebrate community fully ascertained.

Considered data-poor by local wildlife officials, commercially, recreationally and culturally important Amphistichus rhodoterus (redtail surfperch) and common Hyperprosopon ellipticum (silver surfperch) utilize the sandy beach surf zone in Northern California. Little is known about the effect of various environmental factors, …

Plant-Pollinator Interaction Networks In Remnant And Reconstructed Palouse Prairie In Eastern Wa, Usa, Emma Hoskins

EWU Masters Thesis Collection

Ecological restoration is often focused on re-establishing native plant communities, without considering the larger ecological community, specifically pollinators, despite their being critical to native forb reproduction. Further, ecological restoration has the potential to mitigate global pollinator declines by rebuilding native ecosystems, providing pollinators with floral resources and nesting habitat. This is especially true for prairie restoration, which struggles to establish diverse, abundant native forb communities. The USDA Conservation Reserve Program State Acres for Wildlife Enhancement (CRP SAFE) Palouse Prairie Project provides funding to convert agricultural fields into native Palouse Prairie habitat for the benefit of wildlife. Due to financial and …
