Missed Work Due To Occupational Illness Among Hispanic Horse Workers, Ashley M. Bush, Susan C. Westneat, Steven R. Browning, Jennifer Swanberg

Kentucky Injury Prevention and Research Center Faculty Publications

Occupational illnesses are inadequately reported for agriculture, an industry dominated by a vulnerable Hispanic population and high fatal and nonfatal injury rates. Work-related illnesses can contribute to missed work, caused by a combination of personal and work factors, with costs to the individual, employer, and society. To better understand agricultural occupational illnesses, 225 Hispanic horse workers were interviewed via community-based convenience sampling. Descriptive statistics, bivariate analyses, and log binomial regression modeling were used to: (1) describe the prevalence of missed work due to work-related illnesses among Hispanic horse workers, (2) examine work-related and personal factors associated with missed work, and …

Using Colony Monitoring Devices To Evaluate The Impacts Of Land Use And Nutritional Value Of Forage On Honey Bee Health, Matthew D. Smart, Clint R.V. Otto, Robert Cornman, Deborah Iwanowicz

Department of Entomology: Faculty Publications

Colony monitoring devices used to track and assess the health status of honey bees are becoming more widely available and used by both beekeepers and researchers. These devices monitor parameters relevant to colony health at frequent intervals, often approximating real time. The fine-scale record of hive condition can be further related to static or dynamic features of the landscape, such as weather, climate, colony density, land use, pesticide use, vegetation class, and forage quality. In this study, we fit commercial honey bee colonies in two apiaries with pollen traps and digital scales to monitor floral resource use, pollen quality, and …

Tetracycline And Sulfonamide Antibiotic Resistance Genes In Soils From Nebraska Organic Farming Operations, Marylynn Cadena, Lisa M. Durso, Daniel N. Miller, Heidi M. Waldrip, B. L. Castleberry, Rhae A. Drijber, Charles S. Wortmann

Department of Agronomy and Horticulture: Faculty Publications

There is widespread agreement that agricultural antibiotic resistance should be reduced, however, it is unclear from the available literature what an appropriate target for reduction would be. Organic farms provide a unique opportunity to disentangle questions of agricultural antibiotic drug use from questions of antibiotic resistance in the soil. In this study, soil was collected from 12 certified organic farms in Nebraska, evaluated for the presence of tetracycline and sulfonamide resistance genes (n = 15 targets), and correlated to soil physical, chemical, and biological parameters. Tetracycline and sulfonamide antibiotic resistance genes (ARGs) were found in soils from all 12 …

Assessing Intra-Event Phosphorus Dynamics In Drainage Water Using Phosphate Stable Oxygen Isotopes, William Ford Iii, Mark R. Williams, Megan B. Young, Kevin W. King, Eric Fischer

Biosystems and Agricultural Engineering Faculty Publications

Quantifying fluxes and pathways of dissolved reactive phosphorus (DRP) in tile-drained landscapes has been hampered by a lack of measurements that are sensitive to P fate and transport processes. One potential tool to help understand these dynamics is the oxygen isotope signature of phosphate (δ¹⁸O_PO4); however, its potential benefits and limitations are not well understood for intra-event dynamics at the field scale. The objectives of this study were to quantify intra-event variability of δ¹⁸O_PO4 signatures in tile drainage water and assess the efficacy of δ¹⁸O_PO4 to elucidate mechanisms and flow …

A Framework For Tracing Social–Ecological Trajectories And Traps In Intensive Agricultural Landscapes, Daniel R. Uden, Craig R. Allen, Francisco Munoz-Arriola, Gengxin Ou, Nancy Shank

Nebraska Cooperative Fish and Wildlife Research Unit: Staff Publications

Charting trajectories toward sustainable agricultural development is an important goal at the food–energy–water–ecosystem services (FEWES) nexus of agricultural landscapes. Social–ecological adaptation and transformation are two broad strategies for adjusting and resetting the trajectories of productive FEWES nexuses toward sustainable futures. In some cases, financial incentives, technological innovations, and/or subsidies associated with the short-term optimization of a small number of resources create and strengthen unsustainable feedbacks between social and ecological entities at the FEWES nexus. These feedbacks form the basis of rigidity traps, which impede adaptation and transformation by locking FEWES nexuses into unsustainable trajectories characterized by control, stability, and efficiency, …

The Use Of Smart Devices For The Detection Of Aflatoxin In Ground Corn Feeds, Gil Nonato C. Santos, Mary Gillian Santos, Karen Doniza, James Salveo L. Olarve

Angelo King Institute for Economic and Business Studies (AKI)

Aflatoxins are toxic and carcinogenic secondary metabolites produced predominantly by two fungal species: Aspergillus flavus and Aspergillus parasiticus (Gourama, H., & Bullerman, L., 1995). These fungal species are contaminants of food crops as well as animal feeds, and are responsible for aflatoxin contamination of these agricultural products. The toxicity and potency of aflatoxins make them the primary health hazard as well as responsible for losses associated with contaminations of processed foods and feeds (Gourama, H., & Bullerman, L., 1995). Determination of aflatoxins concentration in food crops and animal feeds is thus very important for Food Safety Regulatory Agencies (FRSA) to …

Vitamin Fortification Of Milled Rice: A New Approach To Address Micronutrient Malnutrition, Drexel H. Camacho

Angelo King Institute for Economic and Business Studies (AKI)

To address micronutrient deficiencies in the susceptible sector of society, it is recommended to fortify the commercial milled rice with vitamins using the new technique of fortification. The simple approach, which involves rice surface modification and vitamin absorption, is deemed economical compared to traditional fortification processes. Moreover, the susceptibility of losing vitamins due to washing processes is resolved in this improved grain fortification as ~90% of the vitamins are retained. The results shown in this study indicate the successful fortification of vitamins on rice and that fortification is more pronounced when the grain undergoes sonication process. As the staple food …

Impact Of Physico-Chemical Properties Of Manufactured Nanomaterials On Plant Uptake And Trophic Transfer, Jieran Li

Theses and Dissertations--Toxicology and Cancer Biology

Large quantities of manufactured nanomaterials (MNM) are released into the environment by human activity each year. The entry of MNM into the terrestrial food webs, which has the potential for far-reaching impacts, begins with the uptake by plant species from the soil. These processes can be affected by MNM physico-chemical properties such as size, chemical composition, surface charge, etc., of which our knowledge is still incomplete. To bridge some of the gaps in our understanding of these processes and, specifically, to determine whether the physico-chemical properties of the MNM are predictive of their behavior in terrestrial food chains, we conducted …

The Influence Of Spatiotemporally Decoupled Land Use On Honey Bee Colony Health And Pollination Service Delivery, Matthew D. Smart, Clint R. V. Otto, Benjamin L. Carlson, Cali L. Roth

Department of Entomology: Faculty Publications

Societal dependence on insects for pollination of agricultural crops has risen amidst concerns over pollinator declines. Habitat loss and lack of forage have been implicated in the decline of both managed and native pollinators. Land use changes in the Northern Great Plains of the US, a region supporting over 1 million honey bee colonies annually, have shifted away from historical grassland ecosystems bees rely on for forage toward landscapes dominated by corn, soybeans, and other row crops. We investigated how land use impacts honey bee colony population size during the growing season and subsequent colony population size for almond pollination …

Ecomorphological Associations And Abundance Of Birds Across The Agricultural Landscape Of Pothwar Plateau, Pakistan, Misbah Sarwar, Iftikhar Hussain

Turkish Journal of Zoology

Some species are exceptionally common in landscapes heavily impacted by humans, such as agricultural lands. This study was carried out over a period of 2 years (July 2012 to June 2014) in the arid agricultural landscape of Pothwar Plateau, Pakistan, to identify adaptations that govern bird distribution and abundance across 2 different cropping systems associated with differences in water availability. We used regular surveys and foraging observations to quantify species abundance, distribution, and habits. We then examined morphological correlations with ecological attributes. We found the following: (1) larger birds tended to spend more time in trees; (2) birds with small …

Zoning And Complementary Incentives To Protect Farmland: A Case For Missoula County, Kaitlin Mccafferty

Graduate Student Theses, Dissertations, & Professional Papers

Urban sprawl reflects an inefficient use of land that diminishes both rural landscapes and quality of life turning farms, ranches and open space into siloed suburban communities. This results in less walkable cities with more traffic and air pollution, among other negative consequences. Farmland constitutes a particularly important resource that often faces degradation or loss due to sprawl. Higher quality agricultural soils are particularly desirable for development because they are flat and well-drained. Farmland is also important for urban communities concerning food security, environmental health, and economic well being. As American cities continue to grow, farmland around urban areas has …

Livestock Abundance Predicts Vampire Bat Demography, Immune Profiles And Bacterial Infection Risk, Daniel J. Becker, Gábor Á. Czirják, Dmitriy V. Volokhov, Alexandra B. Bentz, Jorge E. Carrera, Melinda S. Camus, Kristen J. Navara, Vladimir E. Chizhikov, M. Brock Fenton, Nancy B. Simmons, Sergio E. Recuenco, Amy T. Gilbert, Sonia Altizer, Daniel G. Streicker

United States Department of Agriculture Wildlife Services: Staff Publications

Human activities create novel food resources that can alter wildlife–pathogen interactions. If resources amplify or dampen, pathogen transmission probably depends on both host ecology and pathogen biology, but studies that measure responses to provisioning across both scales are rare. We tested these relationships with a 4-year study of 369 common vampire bats across 10 sites in Peru and Belize that differ in the abundance of livestock, an important anthropogenic food source. We quantified innate and adaptive immunity from bats and assessed infection with two common bacteria. We predicted that abundant livestock could reduce starvation and foraging effort, allowing for greater …
