Extended Tailing Of Bacteria Following Breakthrough At The Narrow Channel Focus Area, Oyster, Virginia, Pengfei Zhang, William P. Johnson, Timothy D. Scheibe, Keun-Hyung Choi, Fred C. Dobbs, Brian J. Mailloux

OES Faculty Publications

Extended tailing of low bacterial concentrations following breakthrough at the Narrow Channel focus area was observed for 4 months. Bacterial attachment and detachment kinetics associated with breakthrough and extended tailing were determined by fitting a one-dimensional transport model to the field breakthrough-tailing data. Spatial variations in attachment rate coefficient (k(f)) were observed under forced gradient conditions (i.e., k(f) decreased as travel, distance increased), possibly because of decreased bacterial adhesion with increased transport distance. When pore water velocity decreased by an order of magnitude at 9 days following injection, apparent bacterial attachment rate coefficients did not decrease with velocity as expected …

Structure And Temporal Dynamics Of Populations Within Wheat Streak Mosaic Virus Isolates, Jeffrey S. Hall, Roy C. French, Thomas Jack Morris, Drake C. Stenger

Department of Plant Pathology: Faculty Publications

Variation within the Type and Sidney 81 strains of wheat streak mosaic virus was assessed by single-strand conformation polymorphism (SSCP) analysis and confirmed by nucleotide sequencing. Limiting-dilution subisolates (LDSIs) of each strain were evaluated for polymorphism in the P1, P3, NIa, and CP cistrons. Different SSCP patterns among LDSIs of a strain were associated with single-nucleotide substitutions. Sidney 81 LDSI-S10 was used as founding inoculum to establish three lineages each in wheat, corn, and barley. The P1, HC-Pro, P3, CI, NIa, NIb, and CP cistrons of LDSI-S10 and each lineage at passages 1, 3, 6, and 9 were evaluated for …

High Frequency Of Extra-Pair Paternity In Eastern Kingbirds, Diane L. Rowe, Michael T. Murphy, Robert C. Fleischer, Paul G. Wolf

Biology Faculty Publications and Presentations

Genetic parentage in the socially monogamous and territorial Eastern Kingbird( Tyrannust tyrannus) was examined in a central New York population by multilocus DNA fingerprinting. Extra-pair young were identified in 60% (12 of 20) of nests. Of the 64 nestlings profiled, 42% were sired by extra-pair males, but no cases of conspecific brood parasitism were detected. These results are markedly different from a previous electrophoretic study of the same species in a Michigan population, which reported 39% of nestlings were unrelated to one (typically the mother, quasiparasitismo)r both (conspecificb roodp arasitism) of the putative parents. In the New York population, extra-pairp …

Football Pregame, John Owens

John Owens: Speeches and Appearances

Good afternoon! I am John Owens, and it is my good fortune to be Vice President and Vice Chancellor of Agriculture and Natural Resources. Chancellor Harvey Perlman certainly regrets that he cannot be present at today’s pregame reception. His daughter is being recognized at Ak-Sar-Ben in Omaha, and he’s celebrating this very special occasion with his family.
And speaking of family, I would like to introduce my wife, Dr. Virginia Owens. This probably is the right time for me to confess that both Virginia and I are graduates of Texas Tech. Now, we want everyone to know that “alumni loyalty” …

Transitions In Histone Acetylation Reveal Boundaries Of Three Separately Regulated Neighboring Loci, Michael D. Litt, Melanie A. Simpson, Felix Recillas-Targa, Marie-Noelle Prioleau, Gary Felsenfeld

Department of Biochemistry: Faculty Publications

We have studied developmentally regulated patterns of histone acetylation at high resolution across ~54 kb of DNA containing three independently regulated but neighboring genetic loci. These include a folate receptor gene, a 16 kb condensed chromatin region, the chicken β-globin domain and an adjacent olfactory receptor gene. Within these regions the relative levels of acetylation appear to fall into three classes. The condensed chromatin region maintains the lowest acetylation at every developmental stage. Genes that are inactive show similarly low levels, but activation results in a dramatic increase in acetylation. The highest levels of acetylation are seen at regulatory sites …

The Effect Of Mulching On Herbaceous Wetland Creation Areas In West-Central Florida, Christopher J. Anderson

USF Tampa Graduate Theses and Dissertations

Wetland mulching is the transfer of soil (often from a wetland area which is going to filled or otherwise impacted) on to the surface of a wetland creation area. The primary intent of mulching is to transfer wetland vegetation in the form of seeds and propagules, from the natural wetland to the creation area. This technique also is used to transfer organic matter and microbial fauna existing in the soil to the creation area. My study examines the effects that wetland mulching has on: 1) percent organic matter in the soil, 2) the wetland affinity of plant communities present, 3) …

Accumulation And Consumption Of Odorous Compounds In Feedlot Soils Under Aerobic, Fermentative, And Anaerobic Respiratory Conditions, D. N. Miller

United States Department of Agriculture-Agricultural Research Service / University of Nebraska-Lincoln: Faculty Publications

Agricultural odors present an increasingly difficult challenge to livestock producers, yet very little information is available on the microbiology of odor production or microbial factors that regulate the emission of odors. This study examined the microbial potential for odor production and odor consumption in two soils from a cattle production facility in central Nebraska. The two soils tested were collected from a feedlot pen and a runoff ditch below the pen and contained high- and low-fecal matter content, respectively. These soils were tested for their ability to produce and consume a mixture of VFA and aromatic compounds (phenols and indoles) …

The Land Grant University Movement And Ianr: Animal Science Seminar Series, John Owens

John Owens: Speeches and Appearances

"The problems that exist in the world today cannot be solved by the level of thinking we were at when we created them."

That quote, attributed to Albert Einstein, epitomizes for me the importance of land grant universities in the 21 st century, and whenever I hear someone say that land grants are obsolete - which, occasionally, I do hear - I want to pull that quote out and say "here - read this." When all the problems in the world have been solved, then - and only then - will land grant universities be obsolete. Maybe. I'm …

Monarch Larvae Sensitivity To Bacillus Thuringiensis Purified Proteins And Pollen, Richard L. Hellmich, Blair D. Siegfried, Mark K. Sears, Diane E. Stanley-Horn, Michael J. Daniels, Heather R. Mattila, Terrence A. Spencer, Keith J. Bidne, Leslie C. Lewis

Department of Entomology: Faculty Publications

Laboratory tests were conducted to establish the relative toxicity of Bacillus thuringiensis (Bt) toxins and pollen from Bt corn to monarch larvae. Toxins tested included Cry1Ab, Cry1Ac, Cry9C, and Cry1F. Three methods were used: (i) purified toxins incorporated into artificial diet, (ii) pollen collected from Bt corn hybrids applied directly to milkweed leaf discs, and (iii) Bt pollen contaminated with corn tassel material applied directly to milkweed leaf discs. Bioassays of purified Bt toxins indicate that Cry9C and Cry1F proteins are relatively nontoxic to monarch first instars, whereas first instars are sensitive to Cry1Ab and Cry1Ac proteins. Older instars were …

Corn Pollen Deposition On Milkweeds In And Near Cornfields, John M. Pleasants, Richard L. Hellmich, Galen P. Dively, Mark K. Sears, Diane E. Stanley-Horn, Heather R. Mattila, John E. Foster, Peter Clark, Gretchen D. Jones

Department of Entomology: Faculty Publications

The density of corn pollen on leaves of milkweed plants inside and outside of cornfields was measured in several studies from different localities. The purpose was to obtain a representative picture of naturally occurring pollen densities to provide a perspective for laboratory and field studies of monarch larvae feeding on milkweed leaves with Bt corn pollen. Pollen density was highest (average 170.6 grains per cm²) inside the cornfield and was progressively lower from the field edge outward, falling to 14.2 grains per cm² at 2 m. Inside the cornfield, and for each distance from the field edge, …

Impact Of Bt Corn Pollen On Monarch Butterfly Populations: A Risk Assessment, Mark K. Sears, Richard L. Hellmich, Diane L. Stanley-Horn, Karen S. Oberhauser, John M. Pleasants, Heather R. Mattila, Blair D. Siegfried, Galen P. Dively

Department of Entomology: Faculty Publications

A collaborative research effort by scientists in several states and in Canada has produced information to develop a formal risk assessment of the impact of Bt corn on monarch butterfly (Danaus plexippus) populations. Information was sought on the acute toxic effects of Bt corn pollen and the degree to which monarch larvae would be exposed to toxic amounts of Bt pollen on its host plant, the common milkweed, Asclepias syriaca, found in and around cornfields. Expression of Cry proteins, the active toxicant found in Bt corn tissues, differed among hybrids, and especially so in the concentrations found …

Ambrosia Beetle (Coleoptera: Scolytidae) Species Attacking Chestnut And Captured In Ethanol-Baited Traps In Middle Tennessee, Jason B. Oliver, Catharine M. Mannion

Agricultural and Environmental Sciences Faculty Research

Ambrosia beetles can be important pests of nursery production. The beetles are difficult to control with insecticides, requiring that pesticides be closely timed before tree attack, applied repeatedly, or have long residual activity. The goal of this project was to improve management decisions for ambrosia beetle control in nurseries. This study used ethanol-baited traps, field observations of tree attacks, and emergence cages over beetle galleries to determine the following: (1) composition of ambrosia beetle fauna in middle Tennessee, (2) species responsible for attacks on chestnut (Castanea mollissima Blume), a susceptible tree species, (3) timing of tree attacks and progeny emergence, …

Identification Of Species Composition In The Hong Kong Shark Fin Trade Using Genetic Techniques And Trader Records, Shelley C. Clarke, Mahmood S. Shivji, Murdoch K. Mcallister

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Trade in shark fins represents one of the most serious threats to shark populations worldwide. Previous studies have indicated that certain types of fins are more valued than others, but due to the largely unregulated and often covert nature of the trade, information on actual species composition has been anecdotal and unverified. In order to examine the potential impacts of the shark fin trade on the abundance of various shark species, a study of the species composition in the world’s largest shark fin trading center, Hong Kong, was initiated. Several approaches for distinguishing the species identity of dried fins were …

Familiarity With The Test Environment Improves Escape Responses In The Crimson Spotted Rainbowfish, Melanotaenia Duboulayi, Culum Brown

Sentience Collection

Animals that are familiar with their environment have been reported to have greater survivorship for a number of reasons related to their knowledge of the terrain, which they recall from memory. In an initial experiment rainbowfish significantly improved their escape response towards a novel trawl apparatus over a sequence of five runs. Escape latencies were still low during a subsequent exposure 11 months after the initial exposure. While part of the improvement in escape success was certainly due to learning associated with the location of the escape route, it is likely that this was aided by habituation to the tank …
