CONSUMER POTATO DEMAND
Changes in consumer demographics, socioeconomic conditions, lifestyles, food tastes, and health and nutrition concerns have been associated with shifting food purchase patterns. This article focuses on potato purchase decisions and consumption, using a sample of Washington households. The results suggest that potato purchases are affected by factors such as product quality and price but not availability of point-of-purchase information. Reported changes in fresh and processed potato consumption appeared to be related to concerns with health and nutrition and demand for convenience. These findings have implications for the potato industry in developing new products and marketing strategies.Demand and Price Analysis,
Estimating westslope cutthroat trout (Oncorhynchus clarkii lewisi) movements in a river network using strontium isoscapes
This paper is not subject to U.S. copyright. The definitive version was published in Canadian Journal of Fisheries and Aquatic Sciences 69 (2012): 906-915, doi:10.1139/f2012-033.We used natural variation in the strontium concentration (Sr:Ca) and isotope composition (87Sr:86Sr) of stream waters and corresponding values recorded in otoliths of westslope cutthroat trout (Oncorhynchus clarkii lewisi) to examine movements during their life history in a large river network. We found significant spatial differences in Sr:Ca and 87Sr:86Sr values (strontium isoscapes) within and among numerous spawning and rearing streams that remained relatively constant seasonally. Both Sr:Ca and 87Sr:86Sr values in the otoliths of juveniles collected from nine natal streams were highly correlated with those values in the ambient water. Strontium isoscapes measured along the axis of otolith growth revealed that almost half of the juveniles had moved at least some distance from their natal streams. Finally, otolith Sr profiles from three spawning adults confirmed homing to natal streams and use of nonoverlapping habitats over their migratory lifetimes. Our study demonstrates that otolith geochemistry records movements of cutthroat trout through Sr isoscapes and therefore provides a method that complements and extends the utility of conventional tagging techniques in understanding life history strategies and conservation needs of freshwater fishes in river networks.Bonneville Power Administration, Montana Fish, Wildlife

Contamination in low microbial biomass microbiome studies: issues and recommendations
Next-generation sequencing approaches in microbiome research have allowed surveys of microbial communities, their genomes, and their functions with higher sensitivity than ever before. However, this sensitivity is a double-edged sword because these tools also efficiently detect contaminant DNA and cross-contamination, which can confound the interpretation of microbiome data. Therefore, there is an urgent need to integrate key controls into microbiome research to improve the integrity of microbiome studies. Here, we review how contaminant DNA and cross-contamination arise within microbiome studies and discuss their negative impacts, especially during the analysis of low microbial biomass samples. We then identify several key measures that researchers can implement to reduce the impact of contaminant DNA and cross-contamination during microbiome research. We put forward a set of minimal experimental criteria, the 'RIDE' checklist, to improve the validity of future low microbial biomass research.Raphael Eisenhofer, Jeremiah J.
