Food Security Through Disaster Planning In Tanzania: How Agriculture-Based Disaster Preparedness Can Improve Food Security In Tanzania, Savannah A. Emerich
Food Security Through Disaster Planning In Tanzania: How Agriculture-Based Disaster Preparedness Can Improve Food Security In Tanzania, Savannah A. Emerich
Masters Theses
In Tanzania, half the population lives below the poverty line and suffers from food insecurity. Of the population, women and children primarily suffer from malnutrition due to food insecurity. For Tanzania, the problem is so severe that some women do not name their newborns for weeks or months due to their unlikely survival. This problem worsens for those who have a significant reliance on agriculture and live in the nation’s rural areas. These rural communities face more traumatic burdens when floods and droughts destroy crops, fields, and tools and ruin livelihoods. A solution has not been implemented thus far due …
Comparison Of Bigheaded Carp Reproduction In Tributaries Of The Illinois And Wabash Rivers, David J. Yff
Comparison Of Bigheaded Carp Reproduction In Tributaries Of The Illinois And Wabash Rivers, David J. Yff
Masters Theses
Understanding environmental conditions that support bigheaded carp (Hypophthalmichthys sp.) reproduction in tributary rivers provides key predictions of their invasion throughout the United States. Past research, primarily in larger order rivers, identified factors such as discharge, temperature, and turbidity as main environmental drivers of bigheaded carp reproduction. I used the variable hydrologic conditions between the Illinois and Wabash Rivers to compare environmental conditions between tributaries of each basin, determine which conditions influence bigheaded carp reproduction in tributaries, and predict tributaries likely to support bigheaded carp reproduction. Three tributaries of the Illinois and Wabash Rivers were sampled for ichthyoplankton from …
Differences In The Growth And Bioenergetics Between Centrarchids In A Midwestern Power Plant Lake, Kyle Joseph Rempe
Differences In The Growth And Bioenergetics Between Centrarchids In A Midwestern Power Plant Lake, Kyle Joseph Rempe
Masters Theses
Black Crappie Pomoxis nigromaculatus and Bluegill Lepomis macrochirus are popular sportfishes that co-occur in similar bodies of water throughout most of the Central and Eastern United States but have distinct thermal physiologies. L. macrochirus is often found in warmer regions of freshwater reservoirs, where P. nigromaculatus tends to exploit cooler regions, especially in power plant cooling reservoirs. The coal-fired Coffeen Power Station ceased energy production in October 2019, providing an ideal scenario to study the organismal effects of the sudden shift in thermal regime. Previous studies showed that P. nigromaculatus inhabited the less thermally-impacted areas of Coffeen Lake, whereas L. …
Validation Of Edna Metabarcoding : A Comparison To Traditional Survey Methods In Ozark Streams, Veronica Marian Lee
Validation Of Edna Metabarcoding : A Comparison To Traditional Survey Methods In Ozark Streams, Veronica Marian Lee
Masters Theses
Environmental DNA (eDNA) sampling provides a method for assessing fish communities that has potential as a supplement to traditional sampling methods due to its ability to save time as well as its non-invasive nature. This is a method in which from just one sample, eDNA from multiple individual species are able to be sequenced in tandem and the resulting reads identified to describe a community. In order to evaluate this technique and its efficacy for monitoring fish community diversity, we collected water samples alongside surveys performed by the Missouri Department of Conservation sampling program in summers 2020-21. DNA were extracted …
Development Of Phase Change Thermal Storage Medium: Cooking With More Power And Versatility, Martin Osei
Development Of Phase Change Thermal Storage Medium: Cooking With More Power And Versatility, Martin Osei
Masters Theses
With an Insulated Solar Electric Cooker (ISEC), a 100 W solar panel directly cooks food while providing 5W off-grid electricity access; but it cooks slowly. Storing the day’s energy with phase change thermal storage allows ISEC to cook more rapidly as well as cook after sunset. The ISEC is made by sticking a 3ohm resistive to an aluminum pot (inner phase change assembly PCA) where another cooking pot fits. The resistive heater is surrounded by a bigger pot (outer PCA) that contains the PCM and is tightly sealed. The solar panel is connected to the resistive heater with a thermal …
Low-Head Dam Removal Increases Functional Diversity Of Stream Fish Assemblages, Adam Christopher Jones
Low-Head Dam Removal Increases Functional Diversity Of Stream Fish Assemblages, Adam Christopher Jones
Masters Theses
Despite the growing number of dam removals to date, very few have been studied to understand their impacts on stream fish communities. Despite being the most common type of dam in the U.S., an even smaller proportion of studies focus on the impacts of low-head dam removals, instead, focusing on the impacts of removal of larger dams. In this study, two previously impounded Illinois rivers were monitored to assess the impacts of low-head dam removal on the functional assemblage of stream fishes. This was accomplished by aggregating fishes into habitat and reproductive guilds, relating community changes to habitat, environmental metrics, …
Cloning Of Root-Specific Promoters In Helianthus Annuus And Populus Trichocarpa, Jacob Murphy
Cloning Of Root-Specific Promoters In Helianthus Annuus And Populus Trichocarpa, Jacob Murphy
Masters Theses
Tissue-specific promoters are a valuable tool in plant biotechnology because they allow for precise spatial control of transgene expression. To identify root-specific promoters in sunflower (Helianthus annuus), sunflower RNA sequence (RNA-seq) data were screened in silico by Pavlidis Template Matching (PTM) with a root-specific template. Eight root-specific genes were identified in sunflower. The 2.5kbp promoter regions of six of these root-specific sunflower genes (HaTOR1L3, HaGOXL3A, HaGOXL3B, HaAPA1, HaPOE1, and HaMOP10) were successfully cloned as well as the 3kbp promoter regions of four root-specific genes previously identified in poplar (Populus trichocarpa …

Deciphering The Role Of Mitochondrial Physiology And Thermal Acclimation In Shaping Whole Organismal Performance Of An Invasive Forest Pest, Essa Alrashdi
Masters Theses
Environmental factors such as temperature are substantial determinants of the spongy moth, L. dispar, distribution, reproduction, and growth. Accumulating energy reserves at the larval stage is particularly important to L. dispar, since the larvae metamorphose into a fully-grown, non-feeding adult. As non-feeding adults, the energy balance of the pupae must be adequate, to ensure enough energy reserves for adult dispersal, egg maturation and overall persistence of the species in the region. At this stage, environmental temperature also determines daily metabolic demands, and the overall cost of sustaining ecologically relevant activities. Various hypotheses describing a mismatched growth and metabolic …
