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...
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...
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...
Hatcheries are used to produce salmon to augment the number of fish available for harvest, and to supplement wild populations that may be threatened with extinction. Although traditional hatchery rearing methods can produce many fish, they can pose risk to wild populations because they tend to produce salmon with lower...
In current nanotoxicology research, there is a lack of standardization in reporting of zebrafish exposure media and sonication practices. This lack of standardization in use and reporting methods has made reproducing nanoparticle (NP) toxicity results between labs a common issue. It is important to have a standardized way of reporting...
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, 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...
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...
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...
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...
