Influence of Soil Texture on Carbon Storage of PNW Coastal Blue Carbon Ecosystems

Creator:: Fox, Conner S.
Abstract:: Coastal blue carbon ecosystems offer a variety of important ecosystem services, including exceptional rates of carbon sequestration and long-term carbon storage. Because these ecosystems disproportionately influence global carbon cycling, understanding their soil characteristics may help guide long-term climate change mitigation and adaptation strategies. Recently, Kauffman et al. (2020) observed the...

Old Crops in a New World: Bringing Andean Tuber Crops to the Pacific Northwest

Creator:: Reers, Michelle
Abstract:: Though currently relatively unknown outside Latin America, Andean root and tuber crops are rapidly gaining interest elsewhere. Tubers are a major food and important sources of nutrition in South America and have potential in countries outside their center of origin. We conducted a two-part study on oca (Oxalis tuberosa), mashua...

Identification of Barriers to Industrial Energy Efficiency Improvement in the Pacific Northwest

Creator:: Martz, Allison M.
Abstract:: The US industrial sector accounts for about one-third of the nation’s energy consumption and is predicted to grow twice as quickly as other sectors through 2050. International organizations such as the International Energy Agency project energy efficiency improvements will account for over 40% of greenhouse gas emissions reductions through 2040....

The Distribution and Abundance of a Non-native Eelgrass, Zostera japonica, in Oregon Estuaries

Creator:: Dudoit, Chana Makale’a
Abstract:: Biological introductions may considerably alter the composition and community dynamics of invaded areas thereby changing many ecosystem processes including productivity, decomposition, nutrient cycling and hydrology. The effects on native species may be obscured by a lack of information on distribution and abundance patterns. The Japanese eelgrass, Zostera japonica, was introduced...

Effect of Fire Severity on Forest Development in a Mature Douglas-fir Forest in Western Oregon

Creator:: Hidzick, Maxim S.
Abstract:: Wildfires can create alternative pathways for forest development, and wildfires have expanded in size, frequency, intensity, and severity across the western United States. The purpose of this paper is to compare forest development of a mature Douglas-fir forest in western Oregon across fire severities. Postburn field measurements were collected in...

Genetic and morphological evidence suggests cryptic speciation within the Torrent Sculpin, Cottus rhotheus, across the Pacific Northwest

Creator:: Nicholas, Benjamin P.
Abstract:: Dwelling on the bottom of large rivers to high alpine streams, freshwater sculpins (genus Cottus) occur in high densities across the Pacific Northwest, with 21 currently recognized species found in the Pacific Northwest. Sculpin fill many ecological roles, with some species serving as important prey sources, and others competing with...

Red Raspberry Production Cost Comparison in Oregon and Chile

Creator:: McGuire, Madilynne J.
Abstract:: Red raspberry markets in both Chile and Oregon are affected by factors in each other‟s production processes. As seen in the late 1990‟s changes in pricing and supply can hinder the competitive edge of markets, pushing producers into economic hardship. Thus, the need to know the competition‟s methods is presented....

Honey bee (Apis mellifera) colony strength and its effects on pollination and yield in highbush blueberries (Vaccinium corymbosum)

Creator:: Grant, Kennedy J.
Abstract:: Many pollination studies with honey bees have examined the effect of colony density on crop yield and yet overlook the effect of variation in the population size of these colonies. High colony density in northern highbush blueberry has been met with concerns from beekeepers who feel higher densities will intensify...

Elucidating patterns of fungal epiphyte and endophyte growth on a variety of carbon substrates

Creator:: Thapliyal, Mrinal
Abstract:: Coastal Douglas-fir (Pseudotsuga menziesii var. menziesii), a keystone species in the Pacific Northwest, relies on symbioses with microorganisms to obtain nutrients, potentially defend against pathogens, and perform a variety of other tasks. Two of the tree’s primary fungal symbionts are foliar epiphytes and endophytes, which reside on the exterior or...
