These chemical relationships are represented as a chemical tree that can be visualized in the context of sample metadata and molecular annotations obtained from spectral matching and in silico annotation tools. We show that such a chemical tree representation enables the application of various tree-based tools, originally developed for analyzing DNA sequencing data, for exploring mass-spectrometry data. …

Most pollinators are generalist foragers that can, in some contexts, switch between plant species within a single foraging bout . When pollinators are promiscuous within a single foraging bout, they may transfer heterospecific pollen to floral stigmas, which can have negative effects on both male and female elements of plant reproduction . While heterospecific pollen …

An alkane series was run under the same chromatographic conditions to determine retention indices. Confirmation of identification was performed by comparing the mass spectra and retention indices with those of standards when possible or literature values when standards were not accessible. Relative response was calculated by normalizing peak area for each compound to the internal standard …

This design was implemented based on the assumption that volatiles from treatment plots may be blown or diffuse beyond treatment plots. Berries were brought to the laboratory to determine number of eggs in fruit for each of the plots using a dissecting microscope. All soft or damaged fruits were excluded when assessing presence of eggs. …

The five-year project is part of an effort funded by the U.S. Department of Agriculture to improve scientific knowledge about organic systems and to strengthen the Central Coast network of organic farmers and agricultural researchers . Dan Schmida of Sandpiper Farms is the study’s grower cooperator. Other UCSC researchers involved in the project include Center …

Data were analyzed using a 3-way ANOVA with density of seed , application of B. bassiana , and date as factors . Unrecovered insects were counted as missing data and were not included in the analysis. The commercial blueberry test site selected was located north of Bakersfield in Delano, CA. The trial began in August of …

Many studies have revealed that dormancy plays a crucial role in assisting insects in responding to various phenological environments, including the phenology of different host fruits . The dormant state of tephritids was determined by the rate of growth and development. Therefore, genes associated with development are crucial factors that regulate the adaptation of phenology …

For those less familiar with the Apprenticeship, it is a six month, full-time organic training for up to 38 apprentices from around the world. The roots of the program extend to the arrival of Alan Chadwick at UCSC 40 years ago, when he and a group of student “apprentices” created the Student Garden Project . Apprentices …

Jardineand Sampson were quickly elevated from “special agents” to permanent positions in the Forest Service, becoming “the two pioneers in national forest-range research” . Jardine was promoted to Inspector of Grazing in charge of the new Office of Grazing Studies in 1910, overseeing range research and directing the monumental task of “range reconnaissance” throughout the …

Due to the low concentration of resveratrol specified within the Japanese knotweed rhizome used to simulate the base case model, approximately 6,000 kg of Japanese knotweed rhizomes is needed per batch. While ethanol is widely used across the simulated facility, a large quantity of ethanol at an approximate 1:1 ratio is required during the extraction …
