Plant–Soil Feedback: Bridging Natural And Agricultural Sciences, Pierre Mariotte, Zia Mehrabi, T. Martijn Bezemer, Gerlinde B. De Deyn, Andrew Kulmatiski, Barbara Drigo, G.F. Ciska Veen, Marcel G.A. Van Der Heijden, Paul Kardol

Wildland Resources Faculty Publications

In both agricultural and natural systems, researchers have demonstrated large effects of plant-soil feedback (PSF) on plant growth. However, the concepts and approaches used in these two types of systems have developed, for the most part, independently. Here, we present a conceptual framework that integrates knowledge and approaches from these two contrasting systems. We use this integrated framework to demonstrate how (1) knowledge from complex natural systems can be used to increase agricultural resource-use efficiency and productivity and (2) research in agricultural systems can be used to test hypotheses and approaches developed in natural systems. Using this framework, we discuss …

Aging, Inflammation, And Gut Microbiota In Mice, Jody Demeo

Honors Projects

Inflammation and gut microbiota are two areas of study that can be linked to aging in the body. As a person ages, systemic inflammation tends to increase, and changes in microbiota in the gastrointestinal system occur as well.

Antibiotic Resistance In Escherichia Coli Iron Transport Mutants, Madeline Brandt

Honors Projects

Studies previously completed on Escherichia coli mutants suggested the possibility of iron uptake as an influence on the antibiotic resistance seen in different strains. The research focused on the TonB energy transduction system and its contributions to efflux-mediated antibiotic resistance. To test the hypothesis that iron uptake has an influence on antibiotic resistance in Escherichia coli, the sensitivity to a variety of antibiotics was evaluated in strains of E. coli lacking genes that relate to the uptake of iron or the efflux system that is necessary for the uptake of iron. To test the efflux systems TolC and TonB …

Publications and Research

Floating oil, plastics, and marine organisms are continually redistributed by ocean surface currents. Prediction of their resulting distribution on the surface is a fundamental, long-standing, and practically important problem. The dominant paradigm is dispersion within the dynamical context of a nondivergent flow: objects initially close together will on average spread apart but the area of surface patches of material does not change. Although this paradigm is likely valid at mesoscales, larger than 100 km in horizontal scale, recent theoretical studies of submesoscales (less than ∼10 km) predict strong surface convergences and downwelling associated with horizontal density fronts and cyclonic vortices. …

Keeping Glass Recycling Financially Sustainable: A Cost - Benefit Analysis, Tia Newlove

Honors Projects

Previous research has shown the value that recycled glass, cullet, has in glass container production, road construction and fiberglass production. This cost - benefit analysis explores the value chain of cullet to glass container manufacturers. Glass container manufacturers have a tradeoff between the economic limitations and the environmental benefits of using cullet in the manufacturing process. The cost of cullet is greatly impacted by the location of recycled glass processors relative to the location of glass container manufacturing plants. Strategic investment by glass container manufacturers into maintaining the supply of cullet is essential as recycling programs evolve in the United …

Host Microbiome Regulation Of Hyperthermia Mediated By 3,4-Methylenedioxymethamphetamine (Mdma, Molly), Emily Ridge

Honors Projects

Hyperthermia is one of the most acute and life-threatening consequences of 3,4-methylenedioxymethamphetamine (MDMA) use. The hyperthermia induced by MDMA involves a complex interaction between heat generation and loss of heat dissipation. Recent studies have demonstrated a role for gut microbiome in the regulation of body weight and temperature. Here, we investigated the potential role of the gut microbiome in MDMA-mediated hyperthermia. For fourteen days prior to treatment with MDMA (20 mg/kg, sc) male, Sprague-Dawley rats were provided regular drinking water or drinking water laced with the non-absorbable antibiotics, bacitracin (0.5 mg/mL), neomycin (2mg/mL), and vancomycin (0.2mg/mL). Antibiotic (ABX) treatment reduced …

Groundwater Flood Hazards And Mechanisms In Lowland Karst Terrains, Owen Naughton, Ted Mccormack, Laurence Gill

KIP Articles

The spatial and temporal complexities of flooding in karst terrains pose unique challenges in flood risk management. Lowland karst landscapes can be particularly susceptible to groundwater flooding due to a combination of low aquifer storage, high diffusivity and limited or absent surface drainage. Numerous notable groundwater flood events have been recorded in the Republic of Ireland throughout the twentieth century, but flooding during the winters of 2009 and 2015 was the most severe on record, causing widespread and prolonged disruption and damage to property and infrastructure. Effective flood risk management requires an understanding of the recharge, storage and transport mechanisms …

Structural And Functional Insights Into The Role Of Bamd And Bame Within The Β-Barrel Assembly Machinery In Neisseria Gonorrhoeae, Aleksandra E. Sikora, Igor H. Wierzbicki, Ryszard A. Zielke, Rachael F. Ryner, Konstantin V. Korotkov, Susan K. Buchanan, Nicholas Noinaj

Molecular and Cellular Biochemistry Faculty Publications

The β-barrel assembly machinery (BAM) is a conserved multicomponent protein complex responsible for the biogenesis of β-barrel outer membrane proteins (OMPs) in Gram-negative bacteria. Given its role in the production of OMPs for survival and pathogenesis, BAM represents an attractive target for the development of therapeutic interventions, including drugs and vaccines against multidrug-resistant bacteria such as Neisseria gonorrhoeae. The first structure of BamA, the central component of BAM, was from N. gonorrhoeae, the etiological agent of the sexually transmitted disease gonorrhea. To aid in pharmaceutical targeting of BAM, we expanded our studies to BamD and BamE within …

The Power Of Discomfort In Learning Abroad, Alexis Barge

Capstone Collection

Currently, the majority of students who study abroad do so through short-term programs. In fact, in 2015 over 60% of students who studied abroad chose short-term programs lasting eight weeks or less (IIE, 2016). It has long been the belief that study abroad has the potential to be a life-changing and transformative experience, not just academically but also for personal growth and development. Many professionals agree that the students who go abroad on short-term study abroad programs are significantly less likely to experience meaningful learning outside of the subject matter they are studying, and are less likely to experience personal …

The Lived Experiences Of Parents With Chronic Sorrow Who Are Caring For Children With A Chronic Medical Condition, Lori L. Batchelor

Nursing Theses and Dissertations

Caring for the millions of children living with a chronic medical condition creates multiple parental burdens. Parents whose children have a diagnosis of a chronic medical condition may experience an ongoing, unresolved grief or sadness phenomenon known as chronic sorrow. This may impact parental ability to manage their child’s health care needs and may lead to negative health outcomes for the parent caregiver, affected child, and the family.

The aim of this interpretive phenomenological study was to understand the nature and meaning of the lived experiences of parents with chronic sorrow who are caring for a child with a chronic …

Homogenization Techniques For Population Dynamics In Strongly Heterogeneous Landscapes, Brian P. Yurk, Christina A. Cobbold

Faculty Publications

An important problem in spatial ecology is to understand how population-scale patterns emerge from individual-level birth, death, and movement processes. These processes, which depend on local landscape characteristics, vary spatially and may exhibit sharp transitions through behavioural responses to habitat edges, leading to discontinuous population densities. Such systems can be modelled using reaction–diffusion equations with interface conditions that capture local behaviour at patch boundaries. In this work we develop a novel homogenization technique to approximate the large-scale dynamics of the system. We illustrate our approach, which also generalizes to multiple species, with an example of logistic growth within a periodic …

As keystone species, sea stars serve to maintain biodiversity and species distribution through trophic level interactions in marine ecosystems. Recently, Sea Star Wasting Disease (SSWD) has caused widespread mass mortality in several sea star species from the Pacific Coast of the United States of America (USA) and Asterias forbesi on the Atlantic Coast. A densovirus, named Sea Star associated Densovirus (SSaDV), has been associated with the wasting disease in Pacific Coast sea stars, and limited samples of A. forbesi. The goal of this research is to examine the pathogenesis of SSWD in A. forbesi on the Atlantic …

Oxygen Isotopic Composition Of Nitrate Produced By Freshwater Nitrification, Danielle Boshers

Master's Theses

Identifying sources of nitrate (NO₃^-) in the environment is important to elucidate causes of water quality impairment and eutrophication. Measurements of naturally occurring stable isotope ratios of nitrogen (¹⁵N/¹⁴N) and oxygen (¹⁸O/¹⁶O) in NO₃^-, can be used to determine the sources, dispersal, and fate of natural and contaminant NO₃^- in aquatic environments. To this end, it is necessary to know how NO₃^- isotopologues are modified by biological reactions, as heavy and light isotopes have different reaction rates. One important microbial reaction that …

Iron Reduction Response And Demographic Differences Between Diabetics And Non-Diabetics With Cardiovascular Disease Entered To A Controlled Clinical Trial, Leo Zacharski, Galina Shamayeva, Bruce Chow

Dartmouth Scholarship

Iron-catalyzed oxygen free radical-induced oxidative stress mediates the pathogenesis of diabetes and cardiovascular disease (CVD). Diabetics (n=473) and non-diabetics (n=804) with CVD entered to a randomized trial of iron (ferritin) reduction by calibrated phlebotomy (www.clinicaltrials.gov, Identifier NCT00032357) had comparable iron measures at entry but diabetics had greater burden of CVD and comorbidities, lower hemoglobin and hematocrit levels, and higher glucose levels than non-diabetics. Entry iron measures were lower in diabetics on hypoglycemic therapy compared to diabetics untreated previously. Diabetics and non-diabetics had comparable iron measures during follow-up. Loess analysis of paired ferritin and hemoglobin, and paired ferritin and glucose levels …

Nitrogen Addition And Ecosystem Functioning: Both Species Abundances And Traits Alter Community Structure And Function, Anna R. Tatarko, Johannes M.H. Knops

School of Biological Sciences: Faculty Publications

Increased nutrient inputs can cause shifts in plant community composition and plant functional traits, both of which affect ecosystem function. We studied community- and species-level leaf functional trait changes in a full factorial nitrogen (N), phosphorus (P), and potassium (K) fertilization experiment in a semi-arid grassland. Nitrogen was the only nutrient addition to significantly affect leaf functional traits, and N addition increased community-weighted specific leaf area (SLA) by 19%, leaf chlorophyll content by 34%, height by 26%, and leaf dry matter content (LDMC) decreased by 11% while leaf thickness and toughness did not change significantly. At the species level, most …

Genetic Epidemiology Of Neural Tube Defects, Philip J Lupo, A J Agopian, Heidi Castillo, Jonathan Castillo, Gerald H Clayton, Nienke P Dosa, Betsy Hopson, David B Joseph, Brandon G Rocque, William O Walker, John S Wiener, Laura E Mitchell

Faculty, Staff and Student Publications

It has been estimated that 60-70% of neural tube defects (NTDs) have a genetic component, but few causative genes have been identified. The lack of information on genes associated with non-syndromic NTDs in humans is especially notable as the "genomic revolution" has led to new tools (e.g., genome-wide genotyping arrays, next-generation sequencing) that are helping to elucidate the full spectrum of genetic variation (from common to rare) contributing to complex traits, including structural birth defects. However, the application of modern genomic approaches to the study of NTDs has lagged behind that of some other common structural birth defects. This may …

Do Neonatal Nurses Caring For Newborns With Neonatal Abstinence Syndrome (Nas) Whose Mothers Used Illicit Substances During Pregnancy Experience Moral Distress? A Pilot Study, Valarie Artigas

Doctoral Dissertations

Maternal substance misuse/abuse during pregnancy may lead to adverse neonatal outcomes, including neonatal abstinence syndrome (NAS). NAS is a constellation of withdrawal symptoms exhibited in newborns in response to the discontinuance of in-utero exposure to licit and illicit substances. The incidence of NAS is directly related to the increasing rates of maternal substance use/abuse. The United States has experienced a five-fold increase of newborns born with NAS. The care of the newborn with NAS is one of the most challenging conditions for the neonatal nurse. Management of newborns with NAS requires knowledge that has not been traditionally partnered within care …
