Evolve & Resequence (E&R) experiments subject laboratory populations to environments controlled by investigators, who then document the phenotypic and genomic changes that take place over many generations. These experiments provide powerful tools for testing of a wide variety of evolutionary questions, especially questions about the nature of adaptive traits. While...
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...
The primary goal of this research was to determine the concentration and composition of nucleotides, as nucleoside monophosphates and nucleobases, in the underutilized reproductive organs (milt and roe) of Alaska pollock (Gadus chalcogrammus) and yellowfin sole (Limanda aspera). Changes in concentrations of these nucleotides and nucleotide analogs were observed with...
Under the label “Supported Employment,” services that promote competitive, integrated employment (CIE) for working-age adult with intellectual and developmental disabilities have been federally funded since the 1980s, alongside other more traditional day habilitation and segregated or sub-minimum wage employment services. However, since the early 2000s, over 30 states have adopted...
Research on the population genetics of microbial organisms requires the use of specialized analyses designed for clonal organisms to avoid violating the assumptions of traditional population genetic models. The tools necessary for performing these analyses existed as a set of unrelated software with non-overlapping capabilities and did not cover all...
Multiple outbreaks of foodborne illness (Salmonella and E. coli O157:H7) have been associated with tree nuts and tree nut products since the early 2000s. In response to these outbreaks and many others in fresh produce and peanut butter, Congress created and passed the Food Safety Modernization Act (FSMA) to require...
Lateral spread is a pervasive type of liquefaction-induced ground failure that occurs on gentle slopes or near free-faces, such as river channels. Resulting horizontal displacements can reach up to several meters, and can be considerably damaging to foundations, bridges, roadways, pipelines, etc. In the 1990s, Bartlett and Youd (1992a, 1995)...
Numerous diseases and injuries can limit a person's ability to perform everyday tasks -- things like getting dressed, bathing, and eating. Anything that requires physical activity can be affected; even simple things like turning on the lights can become difficult or impossible. Until recently, the only way for a person...
The Emigrant Pass volcanics (EPV) are a 38.3 to 36.4 Ma calc-alkaline volcanic center that erupted andesite and dacite, and a late series of felsic dikes along the south flank of the Carlin gold district in north-central Nevada. The EPV includes dacite and rhyolite porphyry dikes indistinguishable from porphyry dikes...
Discrete columns, such as stone and soil-cement columns, are often used to improve the liquefaction resistance of loose sandy ground. In particular, stone columns are considered to increase resistance potential by densification, drainage, and reinforcement mechanisms. For silty soil, the shear stress reduction resulting from the reinforcing effect of stiffer...
