Responses Of Sphagnum And Carex Peatlands To Ultraviolet-B Radiation, And A Meta-Analysis Of Uv-B Effects On Vascular Plants, Peter S. Searles

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The severity of stratospheric ozone depletion in the temperate and polar latitudes has raised concerns about the sensitivity of terrestrial vegetation and ecosystems to solar ultraviolet (UV-B) radiation. This dissertation examined the responses of plants and microbes to solar UV-B for 3 years in Tierra del Fuego, Argentina (55° S). This region is under the influence of the Antarctic "ozone hole" during the austral spring. Additionally, a quantitative review of the UV-B literature was conducted using a set of statistical techniques known as meta-analysis.

For the field studies in Tierra del Fuego, plots were established in a Sphagnum moss peatland …

Variation And Heritability Of Phenology In The Fungus Monilinia Vaccinii-Corymbosi On Blueberry, Jeffery S. Lehman, Peter V. Oudemans

Biology and Earth Science Faculty Scholarship

The germination of field-collected pseudosclerotia and the development of apothecia from eight New Jersey populations of the mummy berry fungus Monilinia vaccinii-corymbosi were evaluated under controlled conditions in the greenhouse. Development data for apothecia were used to describe the timing of apothecium formation and to estimate broad- and narrow-sense heritabilities of fungal phenology. Mean development times for the formation of apothecia ranged from 35.4 to 54.7 days. The mean development times for populations collected from early-season cv. Weymouth ranged from 35.4 to 39.6 days and were significantly shorter than the development times for three of the four populations collected from …

Wastewater Management Using Hybrid Poplar, Gary A. Kuhn

Agroforestry Notes (USDA-NAC)

Hybrid poplars are rapidly growing trees that are well suited to use agricultural, industrial, and community wastewater. They are being used as an alternative to expensive wastewater treatment systems, and methods which apply wastewater to annual crops or pasture. The trees serve a dual purpose as a nutrient sink for wastewater use and as a means to produce a short-rotation harvested wood product which helps offset the cost of installation and maintenance.

Planning tree wastewater use systems requires both agroforestry and engineering expertise. Omission of either in the planning process can lead to disappointing results and reduced benefits. This Agroforestry …

Waterbreaks: Managed Trees For The Floodplain, Douglas C. Wallace, Wayne A. Geyer, John P. Dwyer

Agroforestry Notes (USDA-NAC)

Historically, many of the natural woody ecosystems that were once present in floodplains across the country have been highly altered or removed. Land clearing has resulted in the loss of woody vegetation, even in areas adjacent to streams and rivers. With these alterations, came extensive flood management commitments to compensate for the loss of naturally functioning floodplains and for the protection of towns, roads, and agricultural fields. However, even with the best available flood management techniques, when rivers decide to flood - they will, often with devastating consequences. Strictly from a social and an economic standpoint, allowing the floodplain to …

Multiple Source Pools And Dispersal Barriers For Galápagos Plant Species Distribution, J. Alan Yeakley, John F. Weishampel

Environmental Science and Management Faculty Publications and Presentations

We reexamined geographic factors explaining the number of plant species on islands in the Galápagos Archipelago. We hypothesized that plant species richness (S) was related to the number of source pools and that plant species dispersal preferentially followed direct, oceanic pathways. To test different dispersal pathways from multiple source pools, the total number of islands within a given dispersal radius (i) was posed as the sum of the number of line-of-sight islands (C_i) and of the number of islands without line-of sight connection (B_i). In partial regression analyses, controlling for nearest island area (A₂) …

Effects Of Acid Adaptation Of Escherichia Coli O157:H7 On Efficacy Of Acetic Acid Spray Washes To Decontaminate Beef Carcass Tissue, Elaine Berry, Catherine N. Cutter

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

Exposure to low pH and organic acids in the bovine gastrointestinal tract may result in the induced acid resistance of E. coli O157:H7 and other pathogens that may subsequently contaminate beef carcasses. The effect of acid adaptation of E. coliO157:H7 on the ability of acetic acid spray washing to reduce populations of this organism on beef carcass tissue was examined. Stationary-phase acid resistance and the ability to induce acid tolerance were determined for a collection of E. coliO157:H7 strains by testing the survival of acid-adapted and unadapted cells in HCl-acidified tryptic soy broth (pH 2.5). ThreeE. coli …

Effects Of Peeling Methods On The Quality Of Ready-To-Use Carrot Slices, Catherine Barry-Ryan, David O'Beirne

Articles

The effects of methods used for peeling and physiological age (over-wintering) on the quality and storage life of carrot disks packaged in modified atmosphere were examined. Commercial mechanical abrasion peeling using fine or coarse carborundum plates, was compared with carrots peeled by hand, before slicing into disks. Slices which had been peeled by abrasion had higher respiration rates, greater microbial contamination and growth rates, higher pH values, higher rates of weight loss and shorter microbiological shelf-lives than those which had been hand peeled. These results reflected the higher quality of the manually peeled carrots. Micrographs of the peeled surfaces confirmed …

Air Quality And Shelterbelts: Odor Mitigation And Livestock Production, A Literature Review, John Tyndall, Joe Colletti

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

This literature review is focused on the potential for innovative use of trees and other vegetation to reduce the odor associated with livestock production. The goal is to examine available evidence to assess if trees and shelterbelts may: 1) be able to help control odor through physical and biological means, and 2) be an economically feasible technology for livestock producers as well as surrounding communities.

Condition Of Green Ash, Incidence Of Ash Yellows Phytoplasmas, And Their Association In The Great Plains And Rocky Mountain Regions Of North America, J. A. Walla, W. R. Jacobi, N. A. Tisserat, M. O. Harrell, J. J. Ball, G. B. Neil, D. A. Reynard, Y. H. Guo, L. Spiegel

Department of Plant Pathology: Faculty Publications

About 50% of 1,057 green ash (Fraxinus pennsylvanica) systematically sampled in the Great Plains and Rocky Mountain regions had substantial dieback (>10% of crown branches with dieback), and the average growth ring width during the last 20 years was 2.9 mm. The overall condition of the population was rated fair. Ash yellows phytoplasmas were identified at 102 of 106 sites throughout six U.S. states (North Dakota, South Dakota, Wyoming, Nebraska, Colorado, Kansas) and three Canadian provinces (Alberta, Saskatchewan, Manitoba). These phytoplasmas had not previously been known in Alberta, Saskatchewan, Manitoba, Wyoming, Colorado, or Kansas. Incidence of phytoplasmal …

Genetic Diversity And Reproductive Biology In Warea Carteri (Brassicaceae), A Narrowly Endemic Florida Scrub Annual, Margaret E.K. Evans, Rebecca W. Dolan, Eric S. Menges, Doria R. Gordon

Scholarship and Professional Work - LAS

Carter's mustard (Warea carteri) is an endangered, fire-stimulated annual endemic of the Lake Wales Ridge, Florida, USA. This species is characterized by seed banks and large fluctuations in plant numbers, with increases occurring in postdisturbance habitat. We investigated the mating system, patterns of isozyme variation, and effective population sizes of W. carteri to better understand its population biology and to comment on reserve designs and management proposals relevant to this species. Warea carteri is self-compatible and autogamous, and probably largely selfing. Measures of genetic variation in W. carteri were lower than values reported for species with similar ecological …

Characterization Of North American Armillaria Species By Nuclear Dna Content And Rflp Analysis, Mee-Sook Kim, Ned Klopfenstein, Geral I. Mcdonald, Kathiravetpillai Arumuganathan, Anne K. Vidaver

Department of Plant Pathology: Faculty Publications

Twenty-six isolates representing nine North American Armillaria species were investigated with flow cytometry and RFLP (restriction fragment length polymorphism) analyses to determine their nuclear DNA content and RFLP profile. Three putatively diploid isolates of A. ostoyae, A. gemina, A. calvescens, A. sinapina, A. mellea, A. gallica, A. nabsnona, and North American Biological Species (NABS) X were analyzed, and two putatively diploid isolates of NABS XI also were analyzed. Nuclear DNA contents of Armillaria species were 0.11-0.17 pg per nucleus (55-84 X 10" bp/C), depending on species. Among the nine North American Armillaria species tested, A. ostoyae, A. gemirza, and …

Little Known Facts About Alfalfa, Don Ball

Kentucky Alfalfa and Stored Forage Conference

During the previous nineteen Kentucky Alfalfa Conferences, many topics pertaining to alfalfa have undoubtedly been addressed. In fact, some topics such as establishment techniques, varieties, and factors affecting yield are important enough that they have probably been discussed in one form or another during most of these conferences.

However, a twentieth-year state commodity conference is a milestone that deserves some special consideration, and which should justify inclusion of one or more unique topics on the program. This line of thinking led to idea that for this presentation it might be interesting to discuss some facts about alfalfa that are not …

Reducing Alfalfa Harvesting Losses, Michael Collins

Kentucky Alfalfa and Stored Forage Conference

In some areas of the country, producers store a substantial portion of their forage for winter feeding as silage or haylage. However, hay remains the most popular storage method for forage. Hay stores well for long periods and is better suited to cash sale and transportation than silage. Mechanical conditioning, which gained acceptance during the 1950's is probably still the greatest single change in hay harvesting and storage technology during this century. However, a number of other noteworthy changes and innovations have occurred in recent years which have helped to reduce the extent of losses during hay harvesting and storage.

An Efficient Wheat Transformation Procedure: Transformed Calli With Long-Term Morphogenic Potential For Plant Regeneration, Lingyu Zhang, J.J. Rybczynski, W.G. Langenberg, Amitava Mitra, Roy C. French

Department of Plant Pathology: Faculty Publications

A method for producing large numbers of transgenic wheat plants has been developed. With this approach, an average of 9.7% of immature embryo explants were transformed and generated multiple self-fertile, independently transformed plants. No untransformed plants, or escapes, were regenerated. This transformation procedure uses morphogenic calli derived from scutellum tissue of immature embryos of Triticum aestivum cv. Bobwhite co-bombarded with separate plasmids carrying a selectable marker gene (bar) and a gene of interest, respectively. Transformed wheat calli with a vigorous growth phenotype were obtained by extended culture on media containing 5.0 mg/l bialaphos. These calli retained morphogenic potential …
