All Peer-Reviewed Publications

Rhipicephalus decoloratus causes serious economic losses in cattle industry every year in East Africa. Biological control using entomopathogenic fungi is seen as a promising alternative to chemical acaricides being used for their control. The pathogenicity of Metarhizium anisopliae and of Beauveria bassiana isolates was tested in the laboratory against amitraz-resistant and amitraz-susceptible strains of R. decoloratus. Unfed larvae were sprayed with conidial suspensions of 1 × 109 conidia ml-1. Fungal isolates were pathogenic to R. decoloratus larvae, causing mortality of between 10.0 and 100% and between 12.1 and 100% of amitraz-susceptible and amitraz-resistant strains, respectively. The LT50 values of selected …

Coefficients De Diversité Des Populations Dans I'Écosystème Souterrain, R. R. Tercafs

International Journal of Speleology

The evolution of faunal composition in a subterranean cavity of simple structure (Trou des Nutons, Chaudfontaine, Belgium) has been studied. Quantitative comparisons have been carried on in the two most important parts of the cave - the external zone and the deep zone - using diversity and similarity coefficients. It has been found that the external zone presents a great redistribution of the fauna while the deep zone is more stable. However, the whole cave community stays relatively constant during time.

The Role Of Phenotypic Plasticity In The Adaptive Evolution Of Fundulus Heteroclitus, David Isaac Dayan

Open Access Dissertations

Phenotypic plasticity is the ability of a single genotype to produce multiple phenotypes in response to the environment. Because phenotypic plasticity mediates the relationship between genetic variation and the traits that are ultimately subjected to selection, phenotypic plasticity has the potential to influence evolutionary trajectories and contribute to the accumulation and release of cryptic genetic variation. This dissertation investigates both of these themes using a combination of trait level approaches and population genomics. First, the dissertation focuses on variation at the trait level in chapters 2 and 3. Chapter two uses a genome wide association study to demonstrates that the …

The Establishment And Characterization Of Primary Cell Cultures Derived From The Ctenophore Mnemiopsis Leidyi, Kaitlyn J. Warren

Open Access Theses

We have developed a primary cell culture system that can be utilized to isolate adult somatic cell types from Mnemiopsis leidyi, a lobate Ctenophore. Our primary cell cultures are derived from tissue explants and maintained in a complex undefined media, which is generated from tissue isolated from Ctenophore lobes. Approximately 24 hours after explant removal, cultures are screened for the presence of desired cell types. These primary cell cultures can be reliably maintained and visually monitored for a variety of parameters including proliferation, changes in cell morphology and/or differentiation. Exemplar cell types that are easily isolated from primary cultures …

Chemodiversity Of Dissolved Organic Matter In The Amazon Basin, Michael Gonsior, Juliana Valle, Philippe Schmitt-Kopplin, Norbert Hertkorn, David Bastviken, Jenna L. Luek, Mourad Harir, Wanderley Bastos, Alex Enrich-Prast

Civil & Environmental Engineering

Regions in the Amazon Basin have been associated with specific biogeochemical processes, but a detailed chemical classification of the abundant and ubiquitous dissolved organic matter (DOM), beyond specific indicator compounds and bulk measurements, has not yet been established. We sampled water from different locations in the Negro, Madeira/Jamari and Tapajós River areas to characterize the molecular DOM composition and distribution. Ultrahigh-resolution Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR-MS) combined with excitation emission matrix (EEM) fluorescence spectroscopy and parallel factor analysis (PARAFAC) revealed a large proportion of ubiquitous DOM but also unique area-specific molecular signatures. Unique to the DOM of …

The Occurrence Of Hyponatremia And Its Importance As A Prognostic Factor In A Cross-Section Of Cancer Patients, Jorge J. Castillo, Ilya G. Glezerman, Susan H. Boklage, Joseph Chiodo, Beni A. Tidwell, Lois E. Lamerato, Kathy L. Schulman

Public Health Sciences Articles

BACKGROUND: Hyponatremia is prognostic of higher mortality in some cancers but has not been well studied in others. We used a longitudinal design to determine the incidence and prognostic importance of euvolemic and hypervolemic hyponatremia in patients following diagnosis with lymphoma, breast (BC), colorectal (CRC), small cell lung (SCLC), or non-small cell lung cancer (NSCLC).

METHODS: Medical record and tumor registry data from two large integrated delivery networks were combined for patients diagnosed with lymphoma, BC, CRC, or lung cancers (2002-2010) who had ≥1 administration of radiation/chemotherapy within 6 months of diagnosis and no evidence of hypovolemic hyponatremia. Hyponatremia incidence …

Coral Persistence To Ocean Warming Via Developmental Acclimation, Heather L. Schaneen

HCNSO Student Theses and Dissertations

Scleractinian corals are the ‘engineers’ of tropical coral reef ecosystems. Their three-dimensional structure provides habitat for thousands of fish and invertebrate species. The persistence of corals is threatened by climate change. In this study I investigated if corals may be able to increase tolerance to ocean warming through developmental acclimation, i.e. if corals that experience warmer temperatures during embryonic and larval development are better able to cope with higher temperatures later in life. Larvae of the broadcast spawning coral Montastraea cavernosa were raised at ambient (29°C) and future projected ocean warming temperatures (+2°C, 31°C). After larval settlement, coral juveniles from …

Fibropapillomatosis In Marine Turtles: A Comprehensive Review, Samantha L. Mccorkle

HCNSO Student Capstones

Fibropapillomatosis is a disease that affects six of the seven species of marine turtles. The disease was first noticed in 1928, and wasn’t observed again until the 1970s. By the 1980s there was a rapid spread of fibropapillomatosis through the sea turtle population, becoming an endemic in both Florida and Hawaii. By 1995 the concentration of disease in the population reached its climax and has showed a decline in prevalence since. After identifying a viral cause studies began to focus on cultivating the virus in the lab and sequencing, while the virus has been sequenced it has not been successfully …

Use Of Clustering Techniques For Protein Domain Analysis, Eric Rodene

School of Computing: Dissertations, Theses, and Student Research

Next-generation sequencing has allowed many new protein sequences to be identified. However, this expansion of sequence data limits the ability to determine the structure and function of most of these newly-identified proteins. Inferring the function and relationships between proteins is possible with traditional alignment-based phylogeny. However, this requires at least one shared subsequence. Without such a subsequence, no meaningful alignments between the protein sequences are possible. The entire protein set (or proteome) of an organism contains many unrelated proteins. At this level, the necessary similarity does not occur. Therefore, an alternative method of understanding relationships within diverse sets of proteins …

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Advances in automation and data science have led agriculturists to seek real-time, high quality, high-volume crop data to accelerate crop improvement through breeding and to optimize agronomic practices. Breeders have recently gained massive data-collection capability in genome sequencing of plants. Faster phenotypic trait data collection and analysis relative to genetic data leads to faster and better selections in crop improvement. Furthermore, faster and higher-resolution crop data collection leads to greater capability for scientists and growers to improve precision-agriculture practices on increasingly larger farms; e.g., site-specific application of water and nutrients. Unmanned aerial vehicles (UAVs) have recently gained traction as agricultural …

Sensation Seeking And Conscientiousness In Relation To Caffeine Consumption And Expectancy, Cheyenne Bullock

Electronic Theses and Dissertations

Habitual caffeine consumers often report difficulty reducing caffeine use with many continuing to use caffeine despite experiencing symptoms suggestive of substance dependence. Given the evidence of a positive association between sensation seeking and substance use as well as initial reports of a negative relationship between elevated conscientiousness and substance use, this study proposed to evaluate the relationship of both factors on caffeine consumption and expectancy. Two hundred sixty-five students in an introductory psychology course completed a series of brief surveys assessing caffeine consumption, caffeine expectancies, sensation seeking, and conscientiousness. A statistically significant positive correlation was hypothesized for sensation seeking and …

Potential Adverse Effects Of Long Term Use Of Proton Pump Inhibitors., Shreyans M. Doshi, Md, Kazumi A. Khamar, Ms, Inder Sehgal, Dvm, Phd, Nihar Shah, Md Facp

Marshall Journal of Medicine

Proton-Pump Inhibitors (PPIs) have changed the therapy of numerous upper gastrointestinal tract disorders; but their use is not without risk of adverse effects. Recent studies suggest more serious adverse events with chronic use of PPIs. Because of these risks, clinicians should reassess individual patient’s needs for chronic PPI therapy.

A Landscape And Systems Ecology Approach For Predicting Fish Concentration In Seasonally Pulsed And Spatially Heterogeneous Wetlands, Simeon Yurek

Open Access Dissertations

Seasonal pulsing of hydrology in the Greater Everglades watershed produces dynamic, annual cycles of wetland flooding and drying, and of environmental conditions. Biota have adapted to exploit these pulses through movement and foraging behaviors. A primary ecological concern, pertinent to Everglades restoration, is to understand how sufficient concentration of aquatic biomass, particularly that of small fish and invertebrates, is produced under nutrient limited conditions, to support diverse and abundant communities of piscivorous predators, such as wading birds and herpetofauna. This question is investigated through computer simulation modeling of small−bodied fishes in the freshwater Everglades, and analyses of empirical monitoring data …

Acoustic Green's Function Extraction In The Ocean, Xiaoqin Zang

Open Access Dissertations

The acoustic Green's function (GF) is the key to understanding the acoustic properties of ocean environments. With knowledge of the acoustic GF, the physics of sound propagation, such as dispersion, can be analyzed; underwater communication over thousands of miles can be understood; physical properties of the ocean, including ocean temperature, ocean current speed, as well as seafloor bathymetry, can be investigated. Experimental methods of acoustic GF extraction can be categorized as active methods and passive methods. Active methods are based on employment of man-made sound sources. These active methods require less computational complexity and time, but may cause harm to …
