Instar Head Widths, Individual Biomass, and Development Rate of Forest Tent Caterpillar, Malacosoma Disstria (Lepidoptera: Lasiocampidae), At Two Densities in the Laboratory
Get PDFTwo colonies of forest tent caterpillar were reared at different densities on trembling aspen foliage in an environment chamber programmed for natural temperatures. Based on direct observation of molting, both colonies underwent five instars which overlapped negligibly in head width. Instar head widths were relatively stable between colonies, but individual biomass was sensitive to the different densities. Instars 3-5 in the less dense colony were heavier than those of the more dense by factors of 1.3-1.9. Development to 10-20% of larvae spinning cocoons took 40 days in the less dense colony and 45 days in the more dense. Size of larvae and adults resembled that of field samples
#Information: A Content Analysis of the Antifeminist Movement on X
No full textIn response to each wave of the feminist movement, there have been waves of antifeminist backlash, with the contemporary waves largely taking place online. While prior research has examined specific aspects of the most recent wave of this countermovement, none have focused on how we can characterize the antifeminist movement as a whole. To contribute to a more complete understanding, this study sought to determine how the current wave of the antifeminist movement presents itself as a whole online. Using a content analysis of all Tweets posted in a three-month time period under top antifeminist hashtags, this research characterizes the antifeminist movement thematically. I created five categories based upon thematic commonalities among the Tweets, coding each Tweet as belonging to up to three of the categories. The data reveal that a disproportionate number of Tweets contained explicitly misogynistic language, critiqued equality gains for women, and, surprisingly, were majority informational in nature, with authors drawing on academic research and news articles to support the ideas they were promoting. This has important directions for future research, including implications for what the goals of the antifeminist movement are and how the movement chooses to mobilize itself
Uplift Valpo: Building a Leadership Portfilio
No full textOne aspect of being an undergraduate is being able to reflect on student\u27s leadership journey\u27s at Valpo. Because of this, I wanted to work with CITAL and other departments to figure out a way for the university to continue and bring into conversation student leadership and make it a part of the curriculum. As a student who has been involved in over a half a dozen organizations and been a student president of three at the same time, I want to be able to use my knowledge of Valpo and quantify that experience so that other students can maximize their leadership time at VU. I am also looking at other schools and finding out that having a leadership portfolio built into the CORE curriculum is not very common, and as Beacons, we should be trailblazers in providing an education that surpasses other instiutions
Identification of Genetic Loci that Improve Plant Response to Precipitation Extremes
No full textPlant life is facing unprecedented challenges due to erratic weather patterns in the Great Lake Region of the Midwest, characterized by its spring floods and extreme summer heat. We simulated the effects of these extremes in precipitation on 100 Arabidopsis thaliana recombinant inbred lines (RIL) to investigate the quantitative genetics of five phenotypes (days to germinate, bolt, leaf, seed maturity, and flower). We also conducted quantitative trait locus (QTL) mapping to localize genomic regions influencing the phenotypic variation observed in these traits. We identified five QTLs, heritability and gene-by-environment interactions. We are in the process of identifying candidate genes that improve plant resilience to the Midwest’s precipitation extremes
The Etymology of the Beetle Name Lucanus Linnaeus (Coleoptera: Lucanidae)
Get PDF[excerpt]
The handsome European stage beetle Llrcunus cervus Linnaeus is so magnificent in its outlines as to have won the attention of no less a master of drawing than Albrecht Diirer. The spectacular antler-like porrect mandibles of the male assure this creature an important place in any picture book of remarkable insects, and have awakened the linguistic imagination for metaphor. In many of the European languages it is called the flying stag or stag beetle: French cerf vulante. German Hirschkafer, Italian cervo vulante, Dutch uliegende hert, Renaissance Latin scurabelaphus (from Latin scarrcbaeus and Greek elaphus stag ).? This designation can be traced as least as far back as the middle of the 16th century and perhaps further (Imperato 1672:694 [first edition 1559]; Cardanus 1557:301; Lonicerus 1531 [not seen])
A Review of the Biology of the Elm Spanworm (Lepidoptera: Geometridae)
Get PDFThe elm spanworm is a serious defoliator of many species of broadleaved trees, particularly oaks, hickories, black walnut, and red maple. Its life history is reported herein, and the effects of various natural diets on its biology are included. Its different habits of oviposition in the North and South are compared, and early outbreaks are mentioned briefly. Evidence indicates that outbreaks terminate from either late spring frost or one of two recently described egg parasites
The Effects of Pristine and Aged Microplastics on Biofilm Formation and Antibiotic Production
No full textPolypropylene microplastics are some of the most abundant plastic pollutants in the environment. These microplastics provide ideal surface area for the formation of biofilms that can increase the spread of harmful contaminants, such as heavy metals, pathogens, and antibiotics. The current study examines the differences in how pristine microplastics and UV-light aged microplastics affect microbe biofilm formation and production of antibiotics in a 96-well microplate. While many laboratory studies utilize pristine microplastics to determine their effects, pristine microplastics are not always representative of the natural environment. The quick UV aging process allows us to examine how biofilms may form on microplastics that have existed in the environment and degraded naturally for longer periods. Various combinations of a locally sampled soil microbe suspension in water and Streptomyces pure culture were filled in a control condition 96-well microplate and absorbance readings were taken on a weekly basis. Experiments in process include six microplates with added plastics to compare biofilm growth. Each week after reading, successive plates will be scraped out and dilution plated to compare absorbance readings with counted colonies to validate the microplate method over a three-week growth period. Meanwhile, the scraped biofilms will be utilized in several zone of inhibition tests to qualitatively assess antibiotic production

Abscisic acid significantly correlates with increased anthocyanin synthesis in Brassica rapa
No full textDrought stress on plants has increased in intensity, time span, and effected areas in recent years as our climate continues to change. Many plants have stress response adaptations to aid in plant survival through these abiotic conditions such as the abscisic acid hormone or increased anthocyanin synthesis. While these are two known stress responses, it is not yet known whether there is any correlation between these responses that are typically activated in drought environments. This study used a chromatography test on purple hairy-stemmed Brassica rapa plants that underwent drought conditions, with the experimental group receiving an excess concentration of abscisic acid and the control receiving the same treatment amount but of water instead. A significant difference was found between the plants treated with ABA and the control without additional ABA; t(18) =6.69, p=0.001. This study shows that there is a significant positive correlation between the stress hormone abscisic acid and anthocyanin pigmentation when a plant undergoes an abiotic stress, specifically drought. While a significant correlation was found, further studies could explore the exact pathway interactions between these two responses
Investigating π0 and η Production from STAR 2013 Endcap Calorimeter Data
Get PDFThe Solenoidal Tracker at RHIC (STAR) experiment, located at Brookhaven National Laboratory, uses collisions of longitudinally polarized proton beams produced in the Relativistic Heavy Ion Collider (RHIC) to study the gluon contribution to the proton spin. While the proton spin is known to be 1/2 ħ, the contribution from gluon spin is not precisely known. Our analysis uses 300 pb-1 of √s = 510 GeV collisions to determine the asymmetry of spin-dependent production of neutral pions (π0) and eta (η) mesons. This asymmetry is sensitive to the gluon contribution to the spin of the proton. Collisions at √s = 510 GeV have enhanced sensitivity to low x gluons, where x is the fraction of the proton’s momentum carried by the gluon, compared to other STAR analyses. π0s and ηs are produced within the STAR detector via collisions of longitudinally polarized protons provided by RHIC. The π0s and ηs rapidly decay into two photons, which are detected by the Endcap Electromagnetic Calorimeter stationed at a pseudorapidity range of 1.1 \u3c η \u3c 2.0. An invariant mass spectrum is constructed from the photon pairs. From this, the total number of π0s and ηs can be determined. Various quality assurance checks are performed to ensure a thorough understanding of the performance of the STAR detector system and to confirm the robustness of data collection at STAR. The current status of the asymmetry analysis, focusing on the 2013 dataset, will be presented
