RE-IMAGINING WHEAT FOR REGIONAL MARKETS AND AGROECOSYSTEMS
(2017)
The commodification of wheat and its ubiquity in food, society and agriculture belies its potential to contribute to the ecology, nutrition and economies of regional food systems. The craft and science of plant breeding ...

(2017)
Russian-thistle (Salsola tragus L.) is one of the most troublesome weed species in the low- and intermediate-precipitation dryland wheat-fallow cropping zone of the inland Pacific Northwest (PNW). High levels of morphological ...
Economic and Environmental Performance of Mixed Crop-Livestock Farming Systems on the Palouse
(2017)
The global trends of simplifying cropping systems and segregating livestock from cropping enterprises have generated high yields while exacerbating environmental problems globally. To examine the potential for organic and ...
Pyroxsulam Persistence, Adsorption, and Movement in Palouse Soils
(2017)
Instances of herbicide persistence contributing to injury of sensitive rotational crops in the Palouse are common. As a consequence, the Palouse has a reputation for unexpectedly long herbicide persistence among industry, ...
Family poultry systems on the southern pacific coast of Guatemala: livelihoods, ethnoveterinary medicine and Healthcare decision making
(2017)
Small-scale poultry rearing provides a livelihood for many households globally, and is a means for women to contribute to household income while raising children. This is an ethnographic case study of smallholder Guatemalan ...
ECONOMICS OF ORGANIC AND SUSTAINABLE PRODUCTS
(2017)
This dissertation explores how organic and sustainable claims affect prices and consumer willingness to pay (WTP) for food and beverage products in three separate papers. The first paper examines how organic, sustainable, ...
OPTIMIZATION OF POLLINATION AND FRUIT SET IN NORTHERN HIGHBUSH BLUEBERRY
(2017)
Fruit set in northern highbush blueberry (Vaccinium corymbosum L.) can be low under certain climatic conditions, contributing to reduced yields in northwestern Washington. Little is known about the mechanisms of reduced ...
CLIMATE CHANGE IMPACTS AND MITIGATION ON WHEAT SYSTEM IN PACIFIC NORTHWEST
(2017)
Although the world’s food demand is projected to increase due to population growth, the future of the global food supply is not well understood given the complex nature of stressors such as climate change. The goal of this ...
USING NEW MOLECULAR TOOLS TO EXPLORE HOW ORGANIC FARMING IMPACTS TOP-DOWN AND BOTTOM-UP REGULATION OF POTATO HERBIVORES
(2017)
Herbivorous agricultural pests are simultaneously threatened by predatory natural enemies and by toxic plant defenses. Both these “top down” and “bottom up” forces might be enhanced under organic farm management. For ...
