The Effects Of Agrochemical Pesticide Applications On Target And Off-Target Species In Aquatic Ecosystems, Bryan K. Delius

USF Tampa Graduate Theses and Dissertations

The increase in the global human population is driving agricultural expansion, which increases the likelihood and degree by which agrochemicals impact aquatic systems. It is projected that by 2100 the global human population will exceed 11 billion, and to feed the increased human population, the necessary increase in agricultural infrastructure is estimated to double irrigation, nearly triple fertilizer applications, and increase pesticide applications by tenfold. It stands to reason that wetlands impacts from agriculture are also likely to increase as the industry expands its operation to meet the globally growing demand for food.

Wetlands are highly productive habitats that not …

A Fused Radar–Optical Approach For Mapping Wetlands And Deepwaters Of The Mid–Atlantic And Gulf Coast Regions Of The United States, Brian T. Lamb, Maria A. Tzortziou, Kyle C. Mcdonald

Publications and Research

Tidal wetlands are critically important ecosystems that provide ecosystem services including carbon sequestration, storm surge mitigation, water filtration, and wildlife habitat provision while supporting high levels of biodiversity. Despite their importance, monitoring these systems over large scales remains challenging due to difficulties in obtaining extensive up-to-date ground surveys and the need for high spatial and temporal resolution satellite imagery for effective space-borne monitoring. In this study, we developed methodologies to advance the monitoring of tidal marshes and adjacent deepwaters in the Mid-Atlantic and Gulf Coast United States. We combined Sentinel-1 SAR and Landsat 8 optical imagery to classify marshes and …

Cetacean Maternal Investment: Importance In Conservation Across Species And Drivers For Interspecific Altruism, Christopher Klein

USF Tampa Graduate Theses and Dissertations

Cetacean maternal investments can be useful for conservation management as well as examining behaviors such as interspecific altruism in the humpback whale, Megaptera novaeangliae. Cetaceans are among the most threatened group of marine mammals. In the second chapter, maternal investments across ~90 species/subspecies of Cetacea were analyzed to aid in the understanding of recovery/replacement for conservation and management. Using Principal Components Analysis (PCA), a relative maternal-investment index for 41 cetacean species was built. The maternal-investment index was a composite of four maternal-investment variables, the duration of gestation, lactation, calving intervals, and the number of reproduction years per female per species. …

2020 Nebraska Income Averages, Tina N. Barrett

Cornhusker Economics

Each year the numbers gathered by Nebraska Farm Business, Inc tell a story. Sometimes that story is subtle like a drought or storm that affects a small region of the state. Sometimes it is obvious like the drought in 2012, the run-up of commodity prices from 2008-2013, or the impact of the worldwide pandemic of 2020. The one thing that was unique about the story of 2020 was that the sub-stories are not necessarily what you would expect.

In this paper we describe the reporting systems on COVID-19 in Southeast Asia during the first wave in 2020, and highlight the impact of specific reporting methods.

Methods: We reviewed key epidemiological variables from various sources including a regionally comprehensive dataset, national trackers, dashboards, and case bulletins for 11 countries during the first wave of the epidemic in Southeast …

What Do Higher Commodity Prices Mean For Cash Rent?, Allan Vyhnalek

Cornhusker Economics

Anyone watching the corn and soybean prices of the last six months or so must be amazed at how fast and how high prices have gone. Just a year ago, cash prices for 2020 corn were bouncing around the $3.00 per bushel area. Now the cash price for 2020 corn delivered to an ethanol plant is nearly $7.00+ per bushel. What do, or what should, these change in prices do to cash rent?

What Makes A Small Farm Successful? A Review Of Success Factors, Needs, And Challenges, Katie Tritsch, Ken Mix, Michelle L. Edwards, Manuel Piña Jr.

Journal of Extension

Small-scale farmers face unique challenges. In this review, we conceptualize small farm success by aggregating and categorizing results from recent (post-2000) literature on small farm success factors and producer needs assessments. Our findings suggest that small farm success is multifaceted and not limited to profitability. We find that small farms have a diverse range of needs, though little has been done to rank their importance. We conclude that future research would benefit from increased methodological transparency and a systematic approach to needs evaluation. We consider the role of Extension professionals regarding the continued success of small farms.

Where To Draw The Line: Evaluating Visuospatial And Attentional Processing In Individuals With Autism Spectrum Disorders, Alisha Steigerwald

University Honors Theses

Objective: We investigated visuospatial processing in individuals with autism using bisection and quadrisection tasks to evaluate the presence of a possible downward vertical spatial bias that could provide insights into the preference for attending to the mouth in ASD populations.

Methods: Twenty participants with ASD and 20 age, IQ, and sex-matched control participants were recruited (ages 6-23). Participants were asked to bisect, quadrisect from the top, and quadrisect from the bottom vertical lines placed in their left, center, and right visual spaces. Distance from the true midpoint and quadripoint were calculated and compared between the two groups.

Results: No significant …

Understanding Milk Consumption Habits Among College Students In Order To Redesign Outreach, Stacey F. Stearns, Adam N. Rabinowitz

Journal of Extension

College students consume less dairy milk than in the past. Increased competition in the beverage aisle influences their choices. However, much of the population is not meeting the recommended intake guidelines for calcium. A survey of undergraduate college students with university dining plans focused on milk consumption habits, beverage choices, and student attitudes toward healthful foods and nutrition. Results are guiding Extension program educational outreach campaigns to college students. By focusing on the healthful and nutritional benefits of milk, Extension educators could increase consumption among college age consumers, and their long-term healthful outcomes.

Digital Urban Agriculture As Disparate Development: The Future Of Food In Three U.S. Cities Through The Lens Of Stakeholder Perceptions, Networks, And Resource Flows, Michael Carolan

William & Mary Environmental Law and Policy Review

Urban agriculture takes many forms. Often, the term elicits images of raised beds, hoop houses, and, in those instances where topsoil is both present and non-contaminated, in-ground gardens—what I call traditional urban agriculture (“TUA”). But that imagery is changing, especially in some parts of the country where vacant space is scarce and land prices dear. In those instances, cities are seeing growth in digital urban agriculture (“DUA”). DUA, as defined here, refers to farming within urban and peri-urban areas that incorporates elements of automation, software, and/or silicon-based hardware into their operations. While this definition is not meant to draw a …

ARPA provides direct relief to all 19,000 cities, towns and villages across the United States affected by COVID-19. The purpose of ARPA is to support pandemic recovery efforts, replace public sector lost revenue, spur job growth, jump start economic growth through household and business stabilization and ad-dress systemic public health and economic challenges.

Patterns Of Recent Natural Selection On Genetic Loci Associated With Sexually Differentiated Human Body Size And Shape Phenotypes, Audrey M. Arner, Kathleen E. Grogan, Mark Grabowski, Hugo Reyes-Centeno, George H. Perry

Anthropology Faculty Publications

Levels of sex differences for human body size and shape phenotypes are hypothesized to have adaptively reduced following the agricultural transition as part of an evolutionary response to relatively more equal divisions of labor and new technology adoption. In this study, we tested this hypothesis by studying genetic variants associated with five sexually differentiated human phenotypes: height, body mass, hip circumference, body fat percentage, and waist circumference. We first analyzed genome-wide association (GWAS) results for UK Biobank individuals (~194,000 females and ~167,000 males) to identify a total of 114,199 single nucleotide polymorphisms (SNPs) significantly associated with at least one of …

Understanding Producers’ Perspectives On Rotational Grazing Benefits Across Us Great Plains, Tong Wang, Hailong Jin, Urs Kreuter, Richard Teague

Economics Faculty Publications

Experimental findings on rotational grazing (RG) trials have generally differed from producer observations of RG outcomes on commercial scale ranches. Factors such as small plot size, short duration trials and relatively rigid grazing management that lacks responsiveness to the dynamic and complex social-ecological systems in grazing trials could all contribute to this disparity in outcomes. These differences call for a better understanding of producer perceptions of RG benefits. To fill this knowledge gap, we surveyed 4500 producers from the Northern and Southern Great Plains of the USA. Among the 875 respondents, 40.5% reported that they used continuous grazing (CG), 52.7% …

An Analysis Of The Impacts Of Climate Change On Food Security In The Albertine Rift Of East Africa, Malcolm Jacob

Sustainability and Social Justice

As one of the most densely populated regions on the continent of Africa, the Albertine Rift (consisting of parts of Rwanda, Uganda, and the eastern DRC) faces ongoing problems providing enough food for its people through crop production, livestock husbandry, and other forms of food production. Even more troubling for the future is that anthropogenic climate change is expected to significantly exacerbate food insecurity. This paper addresses one central question: how will climate change impact food security in the Albertine Rift? Based on an analysis of available data, this paper finds that policymakers should listen closely to local farmers and …

Towards Consumer-Oriented Mushroom-Based Product Development: An Exploratory Study In Rice-Based Farming Communities In Central Luzon, Philippines, Josefina F. Ballesteros, Rosaly V. Manaois, Amelia V. Morales, Riza Abilgos-Ramos

Journal of Economics, Management and Agricultural Development

This study determined consumers’ awareness and interest towards mushroom and mushroom-based product ideas. A survey of 222 adults was conducted in rice-based farming communities in selected provinces, namely, Aurora,
Bulacan, Nueva Ecija, and Pampanga. Results showed that taste, nutritional, and health benefits were the top attributes considered by both sexes whenever they buy food for household consumption. Most of the respondents (99%) liked eating mushroom because of its palatability (71%) and perceived healthiness (26%). However, the majority (76%) consumed mushrooms only once a month or seldom in a year due to its limited availability. Food supplements, coffee-like beverages, and snacks …

South Dakota Farm Survey

From January to March 2021, researchers from South Dakota State University (SDSU) and Utah State University (USU) conducted a resurvey of South Dakota of commodity crop producers in the eastern part of the state to study their attitudes and usage of soil and water conservation practices including cover crops, diversified crop rotations, conservation tillage, and integrated crop and livestock management. These same producers completed a similar survey in 2018 (see Wang et al. 2021a, b; Saak et al. 2021; Kolady et al. 2020; Avemegah et al. 2020).1 In the 2018 surveys, farming operations in 34 South Dakota counties east of …

Insects As A Sustainable Food Ingredient – Utilization Of Carrot Pomace, Identification Of Early Adopters, And Evaluation Of Mealworm Acceptability, Dominic Rovai

Master's Theses

Insects have been proposed as a sustainable alternative to livestock to help feed the growing population. Edible insects such as mealworms require less land and resources and can utilize food by-products to grow. While insects are consumed by over 2 billion people worldwide, they are not widely accepted in developed countries like the United States because of their unfamiliarity and the perception of disgust associated with entomophagy. The objectives of this research are to 1) grow mealworms using carrot pomace and determine an optimum diet for growth and nutritional composition, 2) identify and classify early adopters of insects, and propose …

Understory Species Increase Project: Investigating The Revegetation Of Native Herbaceous Species From Seed In Urban Forest Fragments, Erin Mcelroy

Environmental Science and Management Professional Master's Project Reports

Management of urban forest fragments often aims to reduce invasive species and promote native species abundance and diversity. Often, these environments lack natural establishment of native forest species, including herbaceous species that are especially sensitive to site conditions. While herbaceous understory species may represent a small proportion of forest biomass, they perform important functions within forest environments, including nutrient cycling, erosion and runoff control, and providing habitat for wildlife, as well as hosting the greatest biodiversity among other forest strata. However, many restoration projects focus primarily on the revegetation of dominant woody forest species, such as hardwood trees and shrubs. …

Influence Of Climate Change On Forest Fire Occurrence And Distribution Of Sri Lanka And Modeling Of Forest Fire, Mohan Heenatigala

Environmental Science and Management Professional Master's Project Reports

Forest fire is one of the main causes for forest degradation and deforestation which affect ecosystem services provided by the given landscapes. Weather variables like temperature, wind speed and direction, rainfall, and relative humidity also govern the forest fire regime and vulnerability. On the other hand, forest fuel characteristics, human impacts, population density, forest canopy density, slope, elevation, road density, closeness to the human settlement areas are other factors that determine the forest fire impact and potential of damage. Annually, 100 to 2500 hectares of forest resources are damaged due to forest fires in Sri Lanka. From the past few …

The first chapter is an introduction to the field of cultural evolution, including a bibliometric analysis of its structure. The second and third chapters are studies on the cultural dynamics of music sampling traditions in hip-hop and electronic music communities and far-right extremism …

Circuits Underlying Serotonin Mediated Sex Differences In Fear Learning, Rebecca Ravenelle

Dissertations, Theses, and Capstone Projects

Post-traumatic stress disorder (PTSD) is a trauma-related disorder characterized by intense fearful memory formation. Women are twice as likely as men to develop PTSD, indicating there may be sex differences in the underlying neural circuits. Given that serotonin (5-HT) dysfunction is implicated in PTSD, and 5-HT modulates fear learning, we investigated whether there are sex differences in the modulation of fear learning by 5-HT. We administered the selective serotonin reuptake inhibitor (SSRI) citalopram (20mg/kg or 10m/kg, i.p.) once to male and female mice prior to auditory fear conditioning and tested the effects on fear memory the next day. We found …
