Body Size And Species Richness Changes In Glyptosaurinae (Squamata: Anguidae) Through Climatic Transitions Of The North American Cenozoic, Sara Elshafie

Department of Earth and Atmospheric Sciences: Dissertations, Theses, and Student Research

Poikilothermic vertebrates offer excellent climate proxies based on relationships between environment and measurable variables such as body size and species richness. Relationships of these variables in lizards to environmental transitions over long time scales are poorly understood. Here I show that patterns of body size and species richness in a lizard clade, Glyptosaurinae (Squamata: Anguidae), correspond to known histories of paleotemperatures through the Cenozoic of North America. Glyptosaurines have the richest fossil record among North American Cenozoic lizards and exhibit a wide range of skull sizes. In order to estimate body size for glyptosaurines and other fossil anguids, I collected …

Mapping The Spatial Movements, Behaviors, And Interactions Of Captive Orangutans Using Terrestrial Laser Scanning And Gis, Zachary Joseph Smith

USF Tampa Graduate Theses and Dissertations

Five captive Bornean orangutans (Pongo pygmaeus) were observed in order to better understand their spatial selection, behavior, and interaction with their environment and each other. A newly introduced adult male's interactions with a female group containing two adults, one adolescent, and one juvenile, was documented. Visual observations were performed to document individual behaviors, along with any interactions with silvery langur monkeys, public crowd levels, temperature, and enrichment props. Methods included 15 observation periods, 0.5-3 hours in length each, during which behaviors were verbally and visually confirmed using a HD video camera. Spatial locations of each individual were recorded every three …

Using Deuterium And Garp To Estimate Geographic Extents Of Source Populations Of Hoary ( Lasiurus Cinereus ) And Eastern Red ( Lasiurus Borealis ) Bats Killed At A Central Illinois Wind Facility, Rachael Anne Van Essen

Theses and Dissertations

High bat mortality at wind energy facilities is a widely cited conservation issue, but the population-level impacts are not understood. In Illinois, the main species affected are migratory tree bats like the Hoary (Lasiurus cinereus) and Eastern Red (Lasiurus borealis).This research used deuterium isotope analysis of hair combined with ecological niche modeling (GARP: Genetic Algorithm for Rule-set Prediction) in a novel way to map the geographic extents of Hoary and Eastern Red bat specimens salvaged at a single central Illinois wind facility from 2008-2010. Hair was chosen after determining that the claw is currently a problematic tissue due to a …

Overview Of The Integrated Pest Management (Ipm) Terrain And Activities In Furtherance Of The Walmart Initiative To Purchase Fresh Vegetables From Local Growers In Alabama, Franklin Quarcoo, Conrad Bonsi

Professional Agricultural Workers Journal

Tuskegee University has been providing various types of technical expertise to limited resource farmers who have been supplying Walmart with collard greens, watermelons and purple hull peas. A number of pests bedevil the cultivation of these crops; cost-effective management methods for these pests are needed. The objectives of this paper are to document the IPM activities associated with supplying produce to Walmart; summarize pest problems encountered on the afore-stated crops; recommend IPM methods suitable for limited resource farmers; and suggest other activities that ensure that farmers incur even less pest-related crop losses. Anthracnose was the major pest encountered on watermelons. …

Dispersal Behavior Of Tetranychus Evansi And T. Urticae On Tomato At Several Spatial Scales And Densities: Implications For Integrated Pest Management, Ginette Y. Azandeme-Hounmalon, Simon Fellous, Serge Kreiter, Komi K.M. Fiaboe, Sevgan Subramanian, Miriam Kungu, Thibaud Martin

All Peer-Reviewed Publications

Studying distribution is necessary to understand and manage the dynamics of species with spatially structured populations. Here we studied the distribution in Tetranychus evansi and T. urticae, two mite pests of tomato, in the scope of evaluating factors that can influence the effectiveness of Integrated Pest Management strategies. We found greater positive densitydependent distribution with T. evansi than T. urticae when assayed on single, detached tomato leaves. Indeed, T. evansi distribution among leaflets increased with initial population density while it was high even at low T. urticae densities. Intensity and rate of damage to whole plants was higher with T. …

Effects Of Landscape Complexity And Habitat Management On Stemborer Colonization, Parasitism And Damage To Maize, Charles A.O. Midega, Mattias Jonsson, Zeyaur R. Khan, Barbara Ekbom

All Peer-Reviewed Publications

Lepidopteran stemborers are a serious constraint to efficient production of maize in sub-Saharan Africa. One of the most effective ways of managing these pests is through a habitat management system called push-pull. Landscape complexity has been shown to enhance biological control of insect pests, and therefore may influence effectiveness of habitat management systems designed to control pests. We studied the relative importance of the push-pull cropping system as a local effect and proportional cover of grassland as a landscape effect on (i) stemborer population density and damage to maize, and (ii) parasitism and mortality of stemborer life stages in western …

Bioremediation Of Crude Oil Spills Impacts Microbial Communities And The Magnetic Susceptibility Of Sediments, Carol L. Beaver, Anja Williams, Estella Atekwana, Gamal Abdel Aal, Farag Mewafy, Lee Slater, Silvia Rossbach

Research and Creative Activities Poster Day

A worldwide increase in the production, shipment, and storage of crude oil has led to an increase in oil spills, and efforts to physically remove this oil from the environment are often insufficient. As a result, hydrocarbon contamination that is not eliminated by suction, excavation, or by dispersants remains in the water and sediments to be degraded by microbes. Initially, the bioremediation of oil occurs aerobically, but as oxygen is depleted, microbes must switch to alternate electron acceptors. Gradients of terminal electron acceptors form over time, which in conjunction with the toxic properties of oil, have an effect on the …

Measuring Viability Of The Red-Tide Dinoflagellate Lingulodinium Polyedra Following Treatment With Ultraviolet (Uv) Light, Scott Riley

HCNSO Student Theses and Dissertations

Harmful algae blooms (HABs) have caused millions dollars in annual losses to the aquaculture industry, inhibited beach recreation, and have threatened marine and human health. HABs and red tides can develop suddenly and their frequency, geographic range, and intensity have increased over the past decade. A possible source for spreading and seeding new areas expanding the geographic range of HABs is ballast water. The process of ballast water discharge has been identified as a primary vector for the translocation of non-indigenous species (NIS) and invasive species. National and international efforts are currently underway to address the impact of NIS and …

Our study was performed from April 5 to April 26, 2014. We utilized compass line quadrat method (n=600) in six sub-populations within three sample frames to achieve non-representative, random data set on richness, diversity, frequency, and density, with metadata from which we extrapolated veld indicators through secondary-source knowledge. Across all sample frames, we found 43 specimens: identified 29 to species, 7 to genus, and left …

Bioremediation Of Polluted Zanzibar Seawater: The Nutrient And Bacterial Bioextraction Potential Of Native Seaweeds And Bivalves, Katie Bergman

Independent Study Project (ISP) Collection

In Stone Town, Zanzibar, increasing populations and insufficient sewage treatment has greatly increased harmful levels of nutrients and anthropogenic-sourced contaminants along the city’s coastal waters. In this study, the nutrient and bacterial bioextractive abilities of local species of bivalves (A. antiquata, P. margaritifera) and seaweeds (E. denticulatum, U. reticulata) were examined in order to determine the potential for these species to remedy the local polluted waters. It was hypothesized that due to bivalves’ suspension-feeding activity, both species of bivalves would be able to decrease turbidity and fecal indicator bacteria (Enterococci) levels in sample polluted …

School of Natural Resources: Faculty Publications

Anthropogenic changes to land cover (LCC) remain common, but continuing land scarcity promotes the widespread intensification of land management changes (LMC) to better satisfy societal demand for food, fibre, fuel and shelter. The biophysical effects of LCC on surface climate are largely understood, particularly for the boreal and tropical zones, but fewer studies have investigated the biophysical consequences of LMC; that is, anthropogenic modification without a change in land cover type. Harmonized analysis of ground measurements and remote sensing observations of both LCC and LMC revealed that, in the temperate zone, potential surface cooling from increased albedo is typically offset …

Uncertainties In Life Cycle Greenhouse Gas Emissions From U.S. Beef Cattle, Quentin M. Dudley, Adam Liska, Andrea K. Watson, Galen E. Erickson

Adam Liska Papers

Beef cattle feedlots are estimated to contribute 26% of U.S. agricultural greenhouse gas (GHG) emissions, and future climate change policy could target reducing these emissions. Life cycle assessment (LCA) of GHG emissions from U.S. grain-fed beef cattle was conducted based on industry statistics and previous studies to identify the main sources of uncertainty in these estimations. Uncertainty associated with GHG emissions from indirect land use change, pasture soil emissions (e.g. soil carbon sequestration), enteric fermentation from cattle on pasture, and methane emissions from feedlot manure, respectively, contributed the most variability to life cycle GHG emissions from beef production. Feeding of …

Effects Of Urban Stream Burial On Organic Matter Dynamics And Reach Scale Nitrate Retention, Jake J. Beaulieu, Paul M. Mayer, Sujay S. Kaushal, Michael J. Pennino, Clay P. Arango, David A. Balz, Timothy J. Canfield, Colleen M. Elonen, Ken M. Fritz, Brian H. Hill, Hodon Ryu, Jorge W. Santo Domingo

All Faculty Scholarship for the College of the Sciences

Nitrogen (N) retention in streams is an important ecosystem service that may be affected by the widespread burial of streams in stormwater pipes in urban watersheds. We predicted that stream burial suppresses the capacity of streams to retain nitrate (NO₃ ⁻) by eliminating primary production, reducing respiration rates and organic matter availability, and increasing specific discharge. We tested these predictions by measuring whole-stream NO₃ ⁻ removal rates using ¹⁵NO₃ ⁻ isotope tracer releases in paired buried and open reaches in three streams in Cincinnati, Ohio (USA) during four seasons. Nitrate uptake lengths were 29 times …

Soybean Nutrient Management In Kentucky, Edwin L. Ritchey, Chad Lee, Carrie Ann Knott, John H. Grove

Agriculture and Natural Resources Publications

Soybean grows best on fertile soils. For decades, the University of Kentucky has conducted field studies to establish the relationship between soil nutrient supplies and soybean yield. Adequate soil fertility must be present so that yields are not limited. Soybean removes a large amount of nutrients in the seed relative to other annual crops. For each bushel of soybean produced, 3 lb N, 0.7 lb P₂O₅, and 1.1 lb K₂O will be removed in the seed, but considerably more is required to supply the leaves, stems and pods that are not removed during harvest …

Study Of The Sustainbility Issues Of Food Production Using Vertical Farm Methods In An Urban Environment Within The State Of Indiana, Victor Mendez Perez

Open Access Theses

There are several problems around the globe related to water scarcity, energy shortages, deforestation and loss of fertile land, and food security. Climate change is making environmental and social issues arise. Issues such as, changes in the agricultural landscape, increasing population (9 billion is the expected population for 2040), rising food borne illnesses, scarcity of drinking water, and more crop failure due to plant pathogens and insect pests, among other factors make this study specially significant. Vertical farming could be a potencial solution to some of these problems.

Due to these problems the present thesis analyzed vertical farming as a …

Improving Indoor Air Quality Through Botanical Air Filtration In Energy Efficient Residences, Daniel William Newkirk

Open Access Theses

According to the U.S. EPA, the average American spends 90% of their time indoors where pollutants are two to five times more prevalent than outside. The consequences of these pollutants are estimated to cost the U.S. 125 billion dollars in lost health and productivity. Background literature suggests botanical air filtration may be able to solve this problem by leveraging the natural ability of plants to purify indoor air. By improving indoor air quality, energy consumption can also be reduced by bringing in less outside air to dilute contaminants within the space. A botanical air filter, called the Biowall, was designed …

Understanding the nexus between deforestation, food production, land degradation, and culture contributes knowledge that is useful for development practitioners working to enhance conservation and food security. Documenting deforestation and soil erosion in the Sierra Yalijux and Sierra Sacranix in the Central Highlands of Guatemala adds new knowledge about the rates and dynamics of deforestation and land degradation in areas with unique and sensitive cloud forest ecosystems. It also suggests possible areas of emphasis for efforts targeted at combining cloud forest conservation with sustainability for indigenous Q'eqchi' communities. In addition, this work contributes to a small but growing body of literature …

Retrofiting Lid Practices Into Existing Neighborhoods: Is It Worth It?, Timothy Wright

Open Access Theses

Low impact development (LID) practices are gaining popularity as a way to manage stormwater close to the source. This reduces infrastructure requirements and helps to maintain hydrologic processes close to predevelopment conditions. Studies have shown LID practices to be effective in reducing runoff and improving water quality. However, little has been done to aid decision makers in selecting the most effective practices for their needs and budgets.

To this end, the L-THIA LID model has been applied. Using readily available data sources, multiple scenarios can quickly be examined, and then analyzed to determine the cost of implementation and the approximate …

Pharmaceuticals And Personal Care Products: Emerging Contaminants In Aquatic Ecosystems, Jenny E. Zenobio

Open Access Theses

In recent years, the presence of pharmaceuticals and personal care products (PPCPs) in aquatic systems has led to research on their fate and effects. PPCPs have been found in mixture in wastewater effluents, surface, ground, and drinking water at low concentrations from areas of intense urbanization. Although adverse effects to human health from the current environmental concentrations are unlikely, the impacts to ecological receptors are not clear. We performed field and laboratory studies to quantify and evaluate effects of PPCPs on fish. First, a field study was conducted at the Baca National Wildlife Refuge, Colorado (2010-2012) because a portion of …
