Agrivoltaics, which integrates photovoltaic power production with agriculture in the same plot of land, has the potential to reduce land competition and crop irrigation. To optimize agrivoltaic systems for crop growth, energy pathways must be characterized. While solar panels shade the crops, they also emit longwave radiation. At the end...
The omnivorous ground beetle, Pterostichus melanarius Illager (Coleoptera: Carabidae), is a ubiquitous inhabitant of western Oregon crop land. Because it is often the most abundant ground beetle, and attains densities that could lead to serious impacts on its prey sources, I sought to understand the overall diet composition, and specifically...
Dense hyphal mats formed by ectomycorrhizal (EcM) fungi are prominent features in Douglas-fir (Pseudotsuga menziesii) forest soils and have been estimated to cover up to 40% of the forest floor in some stands. Although previous studies have examined various aspects of EcM fungi, little is known about their associated microbial...
Working waterfronts across the nation are under pressure. Land use priorities of local governments are changing in response to population growth, new economic pressures, and shifting policy and politics. In Oregon, the decline of fisheries and timber in economic importance followed by the growth of tourism and retirement services has...
Changing environmental conditions in the North Pacific are altering the lipid/fatty acid (FA) composition of zooplankton assemblages, but the consequences to resident fish larvae are unknown. In the laboratory, we reared Pacific cod Gadus macrocephalus larvae over 4 wk on prey enriched with varying levels of 2 essential FAs (docosahexaenoic...
Active-sampling approaches are commonly used for
personal monitoring, but are limited by energy usage and data that may
not represent an individual’s exposure or bioavailable concentrations.
Current passive techniques often involve extensive preparation, or are
developed for only a small number of targeted compounds. In this work,
we present a...

The utility of the fatty acid biomarker (FAB) approach in fisheries ecology is limited by our understanding of how
biotic and abiotic factors determine dietary markers in fish tissues. An 8-week laboratory experiment was
conducted on two species of juvenile gadids (Pacific cod, Gadus macrocephalus and walleye Pollock, Theragra
chalcogramma)...
