Hazelnut and adult hazelnut weevil monitoring at Minnesota sites from 2020-2022
No full textDuring the field seasons of 2020 and 2021, two hazelnut research plantings at the University of Minnesota (one on the St. Paul campus and one at UMore park in Rosemount, MN) were sampled for adult weevils via beat-sheet sampling. This occurred from late May through July of each year. Two plants of six hybrid hazelnut genotypes at each of the hazelnut research plantings, for a total of 24 plants across sites, were sampled as follows: each in-row side plants were sampled for weevils via beat sheet sampling involving one person holding a one-meter canvas cloth under the side of the plant and another person beating about one-half of the plant onto the canvas 10 times with a wooden dowel. Plant/nut phenology characteristics were also recorded each week by randomly measuring the dimensions (height and 2 widths) of five hazelnut clusters on each sampled plant (via digital calipers; eventually to calculate volume), and picking five random nuts from each plant and measuring each hazelnut's respective in-shell volume, shell thickness, and shell hardness. Detailed methods for these measurements can be found in the doctoral dissertation of Hailey N Shanovich that is published with the digital conservancy of the University of Minnesota.
In August of 2020, 2021, and 2022, before hazelnut harvest, every plant in at the hybrid hazelnut planting at the Rosemount, MN was sampled to determine whole-field infestation by hazelnut weevils. Additionally, in 2021, every plant at this site was also beat-sheet sampled in order to record the adult hazelnut weevil abundance on each plant and examine any spatial patterns of adult abundance in the planting. Plant characteristics such as plant height, volume, and genotype were recorded for each plant, as well, in order to examine whether any of these predicted adult weevil abundance or nut infestation.
In 2022, the same hazelnut phenology characteristics were recorded as described above during the hazelnut weevils' egg-laying period as determined from data we collected in 2020 and 2021 for a larger sample of plants of each genotype in order to analyze whether any of these factors differed between hybrid hazel genotypes during their egg-laying period that could describe differences we observed between infestation of the genotypes.

Please contact the author with any questions.This data was collected in order to determine the phenology of adult hazelnut weevils (Curculio obtusus) within interspecific hybrid hazelnut (Corylus americana x Corylus avellana) plantings in Minnesota and identify hazelnut factors that might be driving the weevils within-field abundance and infestation/damage in the crop between different hazelnut genotypes. Adult hazelnut weevil lay eggs into developing hazelnuts and their larvae then develop inside hazelnuts, devouring the edible kernel, directly impacting crop yield. Therefore, the objective was to determine when this behavior occurs in the Minnesota crop and to identify any plant-level or nut-level factors driving spatial trends in their abundance and nut infestation within the hazelnut plantings.University of Minnesota - Bell Museum Award (James Wilkie Fund)United States Department of Agriculture - Specialty Crop Research Initiative (2019-51181-30025)University of Minnesota - Louise T.

Talking to Louise Bourgeois
No full textA narrative text describing a fictive series of events.
The narrator (first person) attempts to interview the celebrated artist Louise Bourgeois in her London studio, and events unfold, leading to his becoming her studio assistant.
The text is interwoven with the narrative of an artist from an unspecified South or Central American country, living in London. There is another text including elements of the first narrative set in a different context, and a further text describing thought processes involved in making a particular painting. The texts serve to problematise the notion of authenticity, identity, originality and the role of the artist. The text is derived from several paintings by the author

Effects of Nitrogen and Phosphorus Input on Lake Louise, Dallas, Luzerne County, PA
No full textThe runoff of nitrogen and phosphorus can be detrimental to a lakes health and ability to support life (Baker, et al. 2007). Eutrophication is a product of large amounts of nitrogen and phosphorous in lakes (Rice and Horgan, 2017). The purpose of this study is to examine if large amounts of nitrogen and phosphorus are present in Lake Louise. The proposed research question is: Are there high concentrations of nitrogen and phosphorus in and around Lake Louise? The null hypothesis of this study is that there will be no significant difference in nitrogen and phosphorus concentrations in areas in and around Lake Louise. The data gathered allowed us to reject the null that there will be no significant difference in nitrogen and phosphorus concentrations in areas in and around Lake Louise. The data shows a trend that the fluctuations in pH, DO, NO3, and NH4 are affected by the time of year, rather than the site. More sampling and gathering of data must be done to properly conclude why Lake Louise is having algae and sediment issues.https://digitalcommons.misericordia.edu/research_posters2021/1056/thumbnail.jp
