Earthworm And Soil Data For Ottawa National Forest, Blair Orr

Michigan Tech Research Data

Two types of analysis were run.

I. Probability of finding L. terrestris in habitat types of the Ottawa National Forests.

Abstract: Parts of the Ottawa National Forest (ONF) provide suitable habitat for invasive earthworms. Extensive earthworm invasion is a relatively recent event on the ONF and this study captures the current state of the earthworm invasion through a four-stage invasive species distribution model (iSDM). The random distribution of earthworms indicates early colonization by earthworms which is moderated by habitat (forest type, soil group, and drainage class). CART modeling was used to determine probability of earthworm invasion. The CART model had …

Water Chemistry And Aquatic Vegetation Data From Les Cheneaux Islands, Northern Lake Huron, Michigan, Usa, 2016-2018, Colin Brooks, Amy Marcarelli, Casey Huckins, Amanda Grimm

Michigan Tech Research Data

Remote sensing approaches that could identify species of submerged aquatic vegetation (SAV) and measure their extent in lake littoral zones would greatly enhance their study and management, especially if they can provide faster or more accurate results than traditional field methods. Remote sensing with multispectral sensors can provide this capability, but SAV identification with this technology must address the challenges of light extinction in aquatic environments where chlorophyll, dissolved organic carbon, and suspended minerals can affect water clarity and the strength of the sensed light signal. Here, we present environmental data collected to support a study using an unmanned aerial …

Data From: Silica Induction Of Diverse Inflammatory Proteome In Lungs Of Lupus-Prone Mice Quelled By Dietary Docosahexaenoic Acid Supplementation, James Pestka, Lichchavi D. Rajasinghe, Abby D. Benninghoff

Browse all Datasets

Repeated short-term intranasal instillation of lupus-prone mice with to crystalline silica (cSiO2) induces inflammatory gene expression and ectopic lymphoid neogenesis in the lung, leading to early onset of systemic autoimmunity and rapid progression to glomerulonephritis. These responses are suppressed by dietary supplementation with the ω-3 polyunsaturated fatty acid docosahexaenoic acid (DHA). Here, we tested the hypothesis that dietary DHA supplementation suppresses cSiO2-induced inflammatory proteins in bronchoalveolar alveolar lavage fluid (BALF) and plasma of lupus-prone mice. Archived tissue fluid samples were used from a prior investigation in which 6 wk-old lupus-prone female NZBWF1 mice were fed isocaloric diets containing 0 or …

Humans are changing the Earth's surface at an accelerating pace, with significant consequences for ecosystems and their biodiversity. Landscape transformation has far-reaching implications including reduced net primary production (NPP) available to support ecosystems, reduced energy supplies to consumers, and disruption of ecosystem services such as carbon storage. Anthropogenic activities have reduced global NPP available to terrestrial ecosystems by nearly 25%, but the loss of NPP from wetland ecosystems is unknown. We used a simple approach to estimate aquatic NPP from measured habitat areas and habitat-specific areal productivity in the largest wetland complex on the USA west coast, comparing historical and …

Energy Expenditure Across Immune Challenge Severities In A Lizard: Consequences For Innate Immunity, Locomotor Performance And Oxidative Status, Susannah S. French, Spencer Hudson

Browse all Datasets

Reptiles, like other vertebrates, rely on immunity to defend themselves from infection. The energetic cost of an immune response is liable to scale with infection severity, prompting constraints on other selfmaintenance traits if immune prioritization exceeds energy budget. In this study, adult male side-blotched lizards (Uta stansburiana) were injected with saline (control) or high (20 μg g−1 body mass) or low (10 μg g−1 body mass) concentrations of lipopolysaccharide (LPS) to simulate bacterial infections of discrete severities. The costs and consequences of the immune response were assessed through comparisons of change in resting metabolic rate (RMR), energy metabolites (glucose, glycerol, …

Lead Toxicology: A Study At The Intersections Of Community Health, Genetics, Reproduction, And Behavior, Sosina Abuhay 23, Lingli Zou '22, Sarah John '24, Dylan Koproski '23

Student Scholarship

Prior literature has indicated that toxic metal exposure can alter the circadian clock rhythm and lead to biological and physiological dysfunction. The purpose of this research was to study the impact of chronic exposure to lead on the circadian rhythm patterns of Drosophila Melanogaster. Fly locomotive activity was used as a measure of strength of the circadian rhythm after exposure to lead. It was hypothesized that higher concentrations of lead would have a greater impact on the circadian locomotor activity patterns of exposed Drosophila, specifically on the transition periods between “Morning” and “Evening.” Young adult male flies(1-3 days post-eclosion) were …

Data From: Yellow Air Day Advisory Study, Arthur J. Caplan

Browse all Datasets

Using a dataset consisting of daily vehicle trips, PM2.5 concentrations, along with a host of climactic control variables, we test the hypothesis that “yellow air day” advisories provided by the Utah Division of Air Quality resulted in subsequent reductions in vehicle trips taken during northern Utah’s winter-inversion seasons in the early 2000s. Winter inversions occur in northern Utah when climactic conditions are such that PM2.5 concentrations (derived mainly from vehicle emissions) become trapped in the lower atmosphere, leading to unhealthy air quality (concentrations of at least 35 µg/m3) over a span of what are called “red air days”. When concentrations …

Regulation Of Gut Commensal-Specific T Cell Differentiation By Dendritic Cell Subsets, Emilie Russler-Germain

Arts & Sciences Electronic Theses and Dissertations

The mammalian gastrointestinal tract can harbor both beneficial commensal organisms important for host health, but also pathogenic organisms capable of intestinal damage. It is therefore important that the host immune system mounts appropriate responses to different intestinal organisms – promoting tolerance to some, controlling the colonization of others, and inducing sterilizing immunity in cases of noxious pathogens. Failure to induce tolerance to commensal organisms may underlie immune-mediated diseases such as human inflammatory bowel disease, while inappropriate tolerance to more harmful organisms has the potential to result in infection, inflammation, or even malabsorption. Adaptive immune responses to intestinal commensal organisms are …

Reeling In New Antibiotics: Synthesis And Antimicrobial Susceptibility Testing Of Zinc-Binding Clavanins From Styela Clava (Sea Squirt), Eduardo Badillo-Colberg

Honors Scholar Theses

Clavanins have been a quite rarely studied antimicrobial peptide (AMP) family. Though the data in the few studies published on the matter and in theoretical experimental data presented by the Wang lab in their peptide library creation [14], in that the members of this family could potentially be quite effective novel antimicrobial candidates. Among those that have been targets of studies, Clavanin A has been at the forefront of this endeavor of finding effective novel antimicrobial peptides[14]. In these aforementioned studies, Clavanin A has been shown to be quite effective against many different bacterial strains, which begs the question as …

Co-Occurrence Of In-Stream Nitrogen Fixation And Denitrification Across A Nitrogen Gradient In A Western U.S. Watershed, 2015 - 2016, Erin K. Eberhard, Amy Marcarelli, Colden V. Baxter

Michigan Tech Publications

This data was collected as part of the NSF CAREER Grant DEB 14-51919 to Amy Marcarelli to evaluate if nitrogen fixation and denitrification co-occur in streams across a gradient of nitrate concentrations. This data was collected during summer 2015 and 2016 in the Portneuf River watershed near Pocatello, ID. In summer 2015, rates of nitrogen fixation were only measured on rock substrate and denitrification only on sediment substrate. In summer 2016, both process rates were measured on both rock and sediment substrate to more accurately capture variation in rates.

Homology Of A Maturase To The Heart Of The Nuclear Spliceosome, Isabella Becker

Undergraduate Research Competition

Structural and biochemical evidence links group II introns as evolutionary precursors of nuclear introns. The spliceosome binds and excises nuclear introns. Maturases are prokaryotic enzymes that aid group II intron excision. The evolutionary ties between group II introns and nuclear introns suggest a possible link between maturases and the nuclear spliceosome. Structural analysis of Prp8, a core enzyme of the nuclear spliceosome has demonstrated this link and revealed similarity to prokaryotic maturases. Maturase K (MatK) is a chloroplast group II intron maturase. Unlike prokaryotic maturases, MatK binds to multiple intron substrates suggesting possible evolution akin to the nuclear spliceosome machinery. …
