Diet overlap by DNA metabarcoding of mule deer, elk, and cattle in ponderosa pine forest of eastern Oregon

Creator:: Faber, M. Kate
Abstract:: Millions of acres of rangeland in the western U.S. is shared habitat by elk (Cervus canadensis), mule deer (Odocoileus hemionus), and cattle (Bos taurus). Potential competition between these ungulates for the same forage species can be understood from their diet composition. I used DNA metabarcoding methods with trnL primers to...

Variation of the Trowbridge's shrew (Sorex trowbridgii) diet across forest types in the Oregon Cascades

Creator:: Yates, Margaret E.
Abstract:: Investigating the insectivorous diet of the Trowbridge’s shrew (Sorex trowbridgii) across forest types can illustrate how forest management affects biotic communities. I used DNA metabarcoding methods with ANML primers to identify stomach and intestines contents from shrews caught in pitfall traps in the HJ Andrews Experimental Forest (HJA) and Willamette...

Analyzing the prevalence of the newly reintroduced sea otter in coyote and wolf diet

Creator:: Garcia, Lani M.
Abstract:: Following their extirpation due to the maritime fur trade, northern sea otter (Enhydra lutris kenyoni) reintroduction in the 1960s has facilitated their recolonization in southeast Alaska. Sea otters are now sympatric with wolves (Canis lupus), which are widespread in southeast Alaska, and a colonizing coyote population (Canis latrans). Recent studies...

The Usefulness of Stable Water Isotopes in Improving Drought Prediction

Creator:: Adams, Logan
Abstract:: Drought represents an import part of natural hydrologic cycles that govern the rate and transportation of water on global and regional scales. (Trenberth, et al. 2015) Agriculturally, drought represents a threat to crop production and can endanger political and economic stability through the loss of resources and the threat of...

Self-regulation differences in preschoolers with speech/language delays compared to their peers

Creator:: Moussaoui, Jannah R.
Abstract:: Self-regulation, defined as one’s ability to control their behaviors, cognitions, and emotions, is an important factor for children’s social, behavioral, and long-term academic performance. Speech/language skills have long been theorized to be important factors in the development of self-regulation and have been linked to various developmental outcomes, particularly in the...

Associations Between Parenting Practices and Decision-Making Competence inEmerging Adults: A Prospective Study

Creator:: Michaels, Linsie
Abstract:: Developmental research has suggested that parenting practices may impact the development of risk behaviors later in life. However, little evidence exists regarding how parenting may impact actual decision processes that precede poor choices. This study examined how parenting practices in early childhood influence the development of decision-making competence (DMC), a...

Comparing the United States West Coast Marine Protected Area levels of protection and their effectiveness to retain viable habitat connectivity with increasing human uses and global change

Creator:: Kesling, Joshua
Abstract:: Coastal communities rely on the abundant ecosystem services derived from robust conservation areas in offshore marine waters (Campbell, 2019). United Nations member states support the Sustainable Development Goal (SDG) framework, wherein the 14th guideline asserts the importance of life under water. Protected marine environments are critical to the survival of...

Impacts of Prior Risk Experience and Personal Values on Support for Climate Change Policies

Creator:: Dwyer, Kiera M.
Abstract:: In 2020, Oregon suffered one of the worst wildfire seasons on record, with a higher percent of forest area burn, the destruction of residential areas, and the risk to human health. The level of intensity of these wildfires were due to the effects of climate change and Oregon wildfire seasons...

Relationship between parasite load and diet quality in two desert bighorn sheep metapopulations in southern California

Creator:: Gibson, Sarah
Abstract:: The increased severity of unseasonal drought conditions in the American Southwest have resulted in herbivorous species, like the desert bighorn sheep (Ovis canadensis nelsoni), receiving lower quality forage in their diet at less reliable frequency. The Mojave Desert and the Peninsular Mountain ranges also contain large variations in elevation, which...

Shifts in Microbial Communities Based Upon Transect Habitat

Creator:: Greydanus, Logan
Abstract:: Coral reef health has been in severe decline around the globe in the past several decades, in many cases due to direct human impact. Human action, such as overfishing, habitat destruction and nutrient loading, has caused coral coverage to drop to record lows, threatening the future of these critically important...
