Conservation of wildlife depends on an understanding of the interactions between animal movements and key landscape factors. Habitat requirements of wide-ranging species often vary spatially, but quantitative assessment of variation among replicated studies at multiple sites is rare. We investigated patterns of space use for 10 populations of two closely...
Across the western US, the two most prevalent native forest insect pests are mountain pine beetle (MPB; Dendroctonus ponderosae; a bark beetle) and western spruce budworm (WSB; Choristoneura freemani; a defoliator). MPB outbreaks have received more forest management attention than WSB outbreaks, but studies to date have not compared their...
The efficacy of DNA extraction protocols can be highly dependent upon both the type of sample being investigated and the types of downstream
analyses performed. Considering that the use of new bacterial community analysis techniques (e.g., microbiomics, metagenomics) is becoming
more prevalent in the agricultural and environmental sciences and many...
Organic semiconductors are of interest for (opto)electronic applications due to their low cost, solution processability, and tunable properties. Natural product-derived organic pigments have attracted attention due to their extraordinary environmental stability and unexpectedly good optoelectronic performance, in spite of only partially conjugated molecular structures. Fungi-derived pigments are a naturally sourced,...
To develop an assay to detect antibodies to Bacillus
thuringiensis subsp. israelensis in mallard ducks, a growth
curve was first established for the bacterium. The growth
curve indicated that the crystal delta endotoxin would be
best harvested from the rest of the cell material after 12
hours of growth. The...
Pacific whiting, with a maximum sustainable yield between 150,000 and 250,000 metric tons, is the largest stock of fish found off Oregon. The majority of the fish are processed into surimi. Hundreds of variables could potentially affect surimi quality (gel strength). Alternative harvesting and processing input combinations, as well as...
