Determining The Viability Of Recent Storms As Modern Analogues For North-Central Gulf Of Mexico Paleotempestology Through Sedimentary Analysis And Storm Surge Reconstruction, Joshua Caleb Bregy 2016 University of Southern Mississippi

Determining The Viability Of Recent Storms As Modern Analogues For North-Central Gulf Of Mexico Paleotempestology Through Sedimentary Analysis And Storm Surge Reconstruction, Joshua Caleb Bregy

Master's Theses

The northern Gulf of Mexico has been devastated by recent intense storms. Camille (1969) and Katrina (2005) are two notable hurricanes that made landfall in virtually the same location in Mississippi. However, fully understanding the risks and processes associated with hurricane impacts is impeded by a short and fragmented instrumental record. Paleotempestology could potentially use modern analogues from intense storms in this region to extend the hurricane record back to pre-observational time. Existing empirically based models can back-calculate surge heights over coastal systems as a function of transport distance, particle settling velocity, and gravitational acceleration. We collected cores in a ...


Drought Impacts On Soil Fertility Management, John E. Sawyer 2016 Iowa State University

Drought Impacts On Soil Fertility Management, John E. Sawyer

John E. Sawyer

If crop production was severely reduced because of dry conditions this year, there are a few items you can consider when planning for next year's crop. One, with severely damaged crops and low yields you might credit some of the phosphorus (P) and potassium (K) applied for this year's crop to next year, as much less removal will occur in grain harvest of the lower than expected yield.

Reducing Pollen Dispersal Using Forest Windbreaks, Carol Auer, Thomas Meyer, Vernie Sagun 2016 University of Connecticut - Storrs

Reducing Pollen Dispersal Using Forest Windbreaks, Carol Auer, Thomas Meyer, Vernie Sagun

Plant Science Articles

The adoption of genetically engineered (GE) crops has created a demand for practical methods to mitigate pollen dispersal and gene flow. The goal of this project was to measure the ability of a narrow forest windbreak to reduce downwind pollen fluxes from switchgrass (Panicum virgatum L.), a North American grass and model biofuels feedstock. Switchgrass fields were established in two identical plots where one had a forest windbreak and the other was in an open (control) site. Switchgrass reproduction, pollen dispersal, wind speed, and wind direction were measured over two years. Daily release of switchgrass pollen peaked at 11:00-13 ...

Hail damage to crops in north central Iowa caused great losses; the total of which will become more defined with harvest. The following guidelines are intended to help farmers through the process of adjusting hail-damaged crops for crop insurance reporting.


Using A High-Altitude Balloon Platform To Observe And Measure Ozone Uptake Over Agricultural Landscapes In Central Illinois, Cody Sabo 2016 DePaul University

Using A High-Altitude Balloon Platform To Observe And Measure Ozone Uptake Over Agricultural Landscapes In Central Illinois, Cody Sabo

DePaul Discoveries

An increase in the amount of factories and machines that emit greenhouse gases (GHGs) has caused the concentration of GHGs to rise steeply since the industrial era. These emissions create compounds that react with sunlight to form ozone, a GHG. Ozone not only traps heat in the atmosphere causing long-term global issues, but it also causes direct harm to both plants and animals. The damage that ozone causes to plants is due to plants taking the gas up through their stomata. Measuring ozone uptake has traditionally been a difficult and expensive process. This study proposes a novel approach towards measuring ...


Combinatory Effect Of Changing Co2, Temperature, And Long-Term Growth Temperature On Isoprene Emissions, Michael Cole 2016 DePaul University

Combinatory Effect Of Changing Co2, Temperature, And Long-Term Growth Temperature On Isoprene Emissions, Michael Cole

DePaul Discoveries

Isoprene, the most abundant hydrocarbon in the atmosphere, plays a significant role in atmospheric chemistry. Its reactions with NOx lead to the formation of ozone in the lower troposphere, which is harmful to plants and detrimental to human health. As air temperatures and CO2 concentrations increase with climate change, it is uncertain how isoprene emissions from plants will respond. We hypothesized that isoprene emissions will increase with the combination of increasing temperature and CO­2 concentrations. We predict that oaks grown at a higher temperature will exhibit an increase in isoprene emissions with combined short-term increases in temperature ...


The Correlation Between Basal Isoprene Emissions And Climate Of The Native Range Across Oak Species, Mary J. Babiez 2016 DePaul University

The Correlation Between Basal Isoprene Emissions And Climate Of The Native Range Across Oak Species, Mary J. Babiez

DePaul Discoveries

Isoprene is a biogenic volatile organic compound that is emitted by various plant species and plays an important role in the chemistry of the atmosphere. When it reacts with pollutants in the air, such as nitrogen oxides, the precursor to ozone (O3) is formed. In this experiment, we measured leaf emissions from 20 different oak species at the Morton Arboretum (Lisle, Illinois). The aim was to better understand differences in isoprene emissions across oak species. Since emissions have been found to protect leaves against brief periods of heat stress, we hypothesized that oaks native to areas with greater variations ...


Pyrosequencing Of Bacterial Symbionts Within Axinella Corrugata Sponges: Diversity And Seasonal Variability, James R. White, Jignasa Patel, Andrea Ottesen, Gabriela Arce, Patricia Blackwelder, Jose V. Lopez 2016 Nova Southeastern University Oceanographic Center

Pyrosequencing Of Bacterial Symbionts Within Axinella Corrugata Sponges: Diversity And Seasonal Variability, James R. White, Jignasa Patel, Andrea Ottesen, Gabriela Arce, Patricia Blackwelder, Jose V. Lopez

Jose Lopez

Background: Marine sponge species are of significant interest to many scientific fields including marine ecology, conservation biology, genetics, host-microbe symbiosis and pharmacology. One of the most intriguing aspects of the sponge ‘‘holobiont’’ system is the unique physiology, interaction with microbes from the marine environment and the development of a complex commensal microbial community. However, intraspecific variability and temporal stability of sponge-associated bacterial symbionts remain relatively unknown.

Methodology/Principal Findings: We have characterized the bacterial symbiont community biodiversity of seven different individuals of the Caribbean reef sponge Axinella corrugata, from two different Florida reef locations during variable seasons using multiplex 454 ...


Metabolites From The Marine-Derived Fungus Chromocleista Sp. Isolated From A Deep-Water Sediment Sample Collected In The Gulf Of Mexico, Young Chul Park, Sarath P. Gunasekera, Jose V. Lopez, Peter J. McCarthy, Amy E. Wright 2016 Florida Atlantic University

Jose Lopez

As part of our ongoing chemical investigation of biologically active metabolites from marine fungi, three new compounds, p-hydroxyphenopyrrozin (1) and diketopiperazines (3, 4), have been isolated from the marine-derived fungus Chromocleista sp. In addition, the fungus gave the known compound phenopyrrozin (2), four known diketopiperazines (6-9), N-acetyltryptamine (10), and agathic acid (11). Another new diketopiperazine (5) was separated and identified as a decomposition product of 3 and 4. The structures of the new metabolites were determined on the basis of mass spectroscopy, NMR experiments, and derivatization methods. The absolute configuration of 1 was determined by X-ray crystallography studies.

Background: Demosponges are challenging for phylogenetic systematics because of their plastic and relatively simple morphologies and many deep divergences between major clades. To improve understanding of the phylogenetic relationships within Demospongiae, we sequenced and analyzed seven nuclear housekeeping genes involved in a variety of cellular functions from a diverse group of sponges.

Methodology/Principal Findings: We generated data from each of the four sponge classes (i.e., Calcarea, Demospongiae, Hexactinellida, and Homoscleromorpha), but focused on family-level relationships within demosponges. With data for 21 newly sampled families, our Maximum Likelihood and Bayesian-based approaches recovered previously phylogenetically defined taxa: Keratosap, Myxospongiae ...

Dynamics Of Marine Bacterial Community Diversity Of The Coastal Waters Of The Reefs, Inlets, And Wastewater Outfalls Of Southeast Florida, Alexandra Mandina Campbell, Jay Fleisher, Christopher D. Sinigalliano, James R. White, Jose V. Lopez

Jose Lopez

Coastal waters adjacent to populated southeast Florida possess different habitats (reefs, oceanic inlets, sewage outfalls) that may affect the composition of their inherent microbiomes. To determine variation according to site, season, and depth, over the course of 1 year, we characterized the bacterioplankton communities within 38 nearshore seawater samples derived from the Florida Area Coastal Environment (FACE) water quality survey. Six distinct coastal locales were profiled – the Port Everglades and Hillsboro Inlets, Hollywood and Broward wastewater outfalls, and associated reef sites using culture-independent, high-throughput pyrosequencing of the 16S rRNA V4 region. More than 227,000 sequences helped describe longitudinal taxonomic ...


Co-Cultures Of Pseudomonas Aeruginosa And Roseobacter Denitrificans Reveal Shifts In Gene Expression Levels Compared To Solo Cultures, Crystal A. Conway, Nwadiuto Esiobu, Jose V. Lopez 2016 Nova Southeastern University Ocenographic Center

Co-Cultures Of Pseudomonas Aeruginosa And Roseobacter Denitrificans Reveal Shifts In Gene Expression Levels Compared To Solo Cultures, Crystal A. Conway, Nwadiuto Esiobu, Jose V. Lopez

Jose Lopez

Consistent biosynthesis of desired secondary metabolites (SMs) from pure microbial cultures is often unreliable. In a proof-ofprinciple study to induce SM gene expression and production, we describe mixed “co-culturing” conditions and monitoring of messages via quantitative real-time PCR (qPCR). Gene expression of model bacterial strains (Pseudomonas aeruginosa PAO1 and Roseobacter denitrificans Och114) was analyzed in pure solo and mixed cocultures to infer the effects of interspecies interactions on gene expression in vitro, Two P. aeruginosa genes (PhzH coding for portions of the phenazine antibiotic pathway leading to pyocyanin (PCN) and the RhdA gene for thiosulfate: cyanide sulfurtransferase (Rhodanese)) and two ...
