Seeds In A Pluriverse: Visakha Society For The Protection And Care Of Animals Inclusive Praxis Toward Self-Determined Just Socio-Ecological Territories, Priya Tallam
Antioch University Dissertations & Theses
My dissertation focuses on my thesis question: How might an NGO’s grassroots efforts in urban Visakhapatnam, India, propagate living justly with animals we encounter and severely Othered humans, beyond attitudes of guardianship, mitigating universalized harms to nature and society? In a transdisciplinary approach examining grassroots programs, my phenomenological study breaks down an animal advocate’s assertive practices of—inclusivity and decolonialized lived norms, which persistently transcend cultural antagonisms of caste, ability, gender, sex, class, and form/species—toward creating just pluriversal multispecies communities in Visakhapatnam. Universalized urbanization across the planet has driven irreversible socio-ecological transformation marked by record ecosystem decline. Sustaining the urban via …
Behavioral Response Of Wild Greater Caribbean Manatees (Trichechus Manatus Manatus) To Playbacks Of Conspecifics In Maya Beach, Belize, Phoebe Sonia Hodson
Behavioral Response Of Wild Greater Caribbean Manatees (Trichechus Manatus Manatus) To Playbacks Of Conspecifics In Maya Beach, Belize, Phoebe Sonia Hodson
Antioch University Dissertations & Theses
The behavioral response of the wild Greater Caribbean manatee (Trichechus manatus manatus) to the acoustic vocalizations of their closely related subspecies, the Florida manatee (Trichechus manatus latirostris), was examined for the first time in Placencia Lagoon, Maya Beach, Belize. The main goal of this study was to determine how vocalizations from conspecifics influence the behavior of the wild Greater Caribbean manatee and how this behavioral change may give insight into the functionality of manatee vocalizations. Three call types (squeak, squeal and high squeak) and chewing sounds were played to varying size aggregations of manatees. Broad behavioral …
Substrate Preference And Foraging Behavior Of Two Declining Warblers In Appalachian Shrublands, Samantha Fishman
Substrate Preference And Foraging Behavior Of Two Declining Warblers In Appalachian Shrublands, Samantha Fishman
Theses and Dissertations
Abstract Shrubland and early successional habitats (ESH) support a diversity of wildlife, including many declining songbirds. However, nonnative shrubs increasingly dominate these habitats, potentially altering habitat quality by influencing prey availability. Habitat quality can be assessed by observing foraging behaviors of songbirds and identifying preferred and avoided substrates as well as testing the predictions of optimal foraging theory; specifically that birds will maximize their energy gain relative to the costs. We examined foraging behaviors of Golden-winged Warblers (Vermivora chrysoptera; GWWA) and Chestnut-sided Warblers (Setophaga pensylvanica; CSWA) in ESH on private lands in Virginia with varying amounts …
Textual Sediments: Genre And The Planetary Novel, William Bowden
Textual Sediments: Genre And The Planetary Novel, William Bowden
Open Access Dissertations
This dissertation investigates how twenty-first-century prose fiction navigates the ecological and temporal dimensions of planetary crisis. In response to accelerating pressures - climate change, ecological collapse, and the intensification of capitalist modernity - literary studies has turned increasingly to the planetary as a conceptual frame. Yet this shift has often outpaced the development of adequate critical vocabularies and narrative methodologies. By drawing on ecocriticism, narrative theory, phenomenology, and related fields, Textual Sediments proposes a new framework for reading what it terms the planetary novel: a sedimentary genre characterized by temporal layering, formal hybridity, and a recursive engagement with scale. Through …

Open Access Dissertations
This dissertation investigates the critical issue of seaport resilience, focusing on the gaps in resilience planning and the role of incentives in motivating resilience investment. The research arc addresses the question: What incentivizes seaports to increase natural hazard resilience (NHR)? It is organized into three interconnected manuscripts, each examining distinct aspects of the problem.
The first manuscript critically examines the resilience planning approaches of Small Island Developing States (SIDS) as outlined in their National Adaptation Plans (NAPs), highlighting the limited consideration of seaports despite their critical role in economic and social connectivity. SIDS offer critical insight into seaport resilience due …
Climate Variability Study For Arid Regions, Faisal Almutairi
Climate Variability Study For Arid Regions, Faisal Almutairi
Electronic Theses and Dissertations
Water is the primary source for all living species to thrive, and water scarcity has been a primary concern for biological species and plants in arid regions due to urban planning, population growth, poor water management, and overgrazing. The objective of this research was to study the climate variability in precipitation and temperature for an arid region. This research encompasses two distinct studies. The first study examined the impact of climate variability on precipitation in Phoenix. Precipitation data were acquired from NOAA from 1948 to 2023 and the study was broken down into three time scales: annually, seasonally, and monthly. …
Prospective Use Of Detection Dogs As A Screening Tool For Mycoplasma Ovipneumoniae In Bighorn Sheep (Ovis Canadensis), Michele C. Lovara
Prospective Use Of Detection Dogs As A Screening Tool For Mycoplasma Ovipneumoniae In Bighorn Sheep (Ovis Canadensis), Michele C. Lovara
Electronic Theses and Dissertations
Mycoplasma ovipneumoniae is a bacterium that can spill over from domestic sheep (Ovis aries) to bighorn sheep (Ovis canadensis), with effects in bighorn sheep ranging from low to no lamb recruitment to whole-herd all-age die-offs from resulting pneumonia. Fast and reliable pathogen or disease detection is essential for managing outbreaks in bighorn sheep and emergences in affected populations. Detection dogs are increasingly being enlisted to close gaps and further complement various disease, pathogen and virus research and response efforts. This thesis explores the use of conservation detection dogs as a potential tool for M. ovipneumoniae surveillance in bighorn sheep through …
Quantifying Avian And Vegetation Communities On Agricultural Conservation Easement Wetlands In Eastern South Dakota, Katherine Millman
Quantifying Avian And Vegetation Communities On Agricultural Conservation Easement Wetlands In Eastern South Dakota, Katherine Millman
Electronic Theses and Dissertations
The Prairie Pothole Region of eastern South Dakota contains numerous small depressional wetlands, colloquially known as potholes, that provide important ecosystem services, including water storage, water quality improvement, and wildlife habitat. The Agricultural Conservation Easement Program (ACEP) was established by the U.S. Department of Agriculture to protect and restore wetlands and grasslands on private land through easements such as Wetland Reserve Easements. Although ACEP requires management practices intended to maintain or improve habitat quality, few studies have evaluated their effectiveness at supporting wildlife communities and vegetation integrity. To address this gap, we evaluated wetlands at 30 ACEP sites and 20 …
Investigating Non-Invasive Survey Methods And Building A Predictive Occupancy Model For Harlequin Ducks (Histrionicus Histrionicus) In Western Montana And Northern Idaho, Holli Ann Holmes
Graduate Student Theses, Dissertations, & Professional Papers
Harlequin Ducks (Histrionicus histrionicus; HADU) are an imperiled sea duck that breeds along white-water mountain streams, but challenges in surveying them have made it difficult to understand population trends in their Northern Rocky Mountain breeding population. In this study we had two objectives: (1) evaluate non-invasive survey methods for detecting HADU on their breeding grounds in Western Montana and Northern Idaho, and (2) develop an occupancy model to predict potential breeding stream use for HADU across the region. First, we assessed the efficacy of ground-based foot surveys (GBS), environmental DNA (eDNA), and camera traps to detect breeding HADU during …
Avoiding Racial Equity Detours: Racial Equity Trainers’ Visions Of Racially Equitable Residential Environmental Education, Anna Mooney Ph.D.
Avoiding Racial Equity Detours: Racial Equity Trainers’ Visions Of Racially Equitable Residential Environmental Education, Anna Mooney Ph.D.
Antioch University Dissertations & Theses
This study investigated how racial equity trainers envision racially equitable residential environmental education (REE). While addressing racial inequities has been central to environmental scholarship, equity detours undergirded by systemic power structures continue to pose significant barriers in addressing inequities in practice. The research explored the question: “How do racial equity trainers envision racially equitable residential environmental education?” Using constructivist grounded theory and drawing on portraiture’s “search for goodness,” the study conducted 1-hour virtual interviews with six racial equity trainers, employing iterative coding through the constant comparative method. A 2-hour virtual focus group and subsequent 30-minute “dissertation reality check” provided additional …
Canary In The Alpine: Shifts In Snowbed Plant Communities Over Time In The Adirondack Mountains Of New York, Katie Rhodes
Canary In The Alpine: Shifts In Snowbed Plant Communities Over Time In The Adirondack Mountains Of New York, Katie Rhodes
Antioch University Dissertations & Theses
Due to their unique species diversity and vulnerability, alpine snowbed communities have the potential to serve as early detection or ‘canary’ communities that can inform scientific understanding of the timing and physical manifestation of a changing alpine ecosystem. In the summer of 2008, fifteen alpine snowbed vegetation community transects over 5 mountain summits were established and studied in the High Peaks Wilderness Complex within the Adirondack State Park by the New York Natural Heritage Program. Each transect was 5 meters long and encompassed five 1x1 meter subplots. These transects were relocated and surveyed again in the summer of 2024 in …

Synthesis And Characterization Of A Biobased Polymer From Tung Oil And Pine Rosin & Characterization Of Polyhydroxybutyrate., Arijanet P. Osumah
College of Graduate Studies: Theses & Dissertations
This thesis presents two independents but thematically aligned research projects focused on the development and evaluation of sustainable polymers. The first involves the synthesis and characterization of a biobased polymer derived from tung oil and pine rosin. Tung oil, which is a triglyceride was chemically modified to produce tung oil diglyceride (TDG), which subsequently reacted with abietic acid-rich pine rosin to yield tung oil abietate (TOA), a biobased monomer. The TOA monomer was polymerized with butyl methacrylate (BMA) and divinylbenzene (DVB) using di-tert-butyl peroxide (DTBP) as a thermal initiator. The resulting polymer was thoroughly characterized using Fourier transform infrared spectroscopy …

Huanglongbing (HLB), also known as citrus greening disease, poses a severe threat to the global citrus industry. This disease is caused by three species of bacteria, ‘Candidatus Liberibacter asiaticus’, ‘C. L. africanus’, and ‘C. L. ameri-canus’. The primary pathogen vectors are the Asian citrus psyllid (Diaphorina citri Kuwayama, Hemiptera: Psyllidae) and the African citrus psyllid (Trioza erytreae Del Guercio, Hemiptera: Triozidae). The disease is incurable, and its management relies on reducing vector densities and the adverse effects of bacterial infections on host trees. Managing psyllid vec-tors, especially D. citri, has proven exceptionally challenging due to its rapid spread and subsequent …

Widespread coral bleaching and mortality events are becoming increasingly frequent due to rising ocean temperatures, though certain coral species and populations have displayed higher tolerance to elevated emperatures than others. As such, it is of high research priority to identify thermally tolerant coral populations for research and conservation and assess the biological mechanisms allowing these populations to survive exposure to higher temperatures. This research utilized the Coral Bleaching Automated Stress System (CBASS), a portable experimental aquaria system with precise temperature manipulation, to assess the thermal thresholds and heat stress response of two coral species from Summerland Key, FL, USA. Seven …

Heterotrophy Of Particulate Organic Matter Subsidies Contributes To Divergent Bleaching Responses In Tropical Sclaractinian Corals, Connor R. Love, Kelly E. Speare, Michael D. Fox, Veronica Z. Radice, Kelton W. Mcmahon, Gretchen E. Hofmann,, David L. Valentine, Marie E. Strader
Biological Sciences Faculty Publications
Heterotrophic feeding on plankton and particulate organic matter (POM) by tropical Scleractinian corals is known to aid in the resistance and recovery from thermally induced bleaching. However, the relative importance of heterotrophy in promoting bleaching resistance and recovery is likely to vary based on ecological context and the severity of heat stress. In 2019, the Pacific Island of Mo'orea experienced mass coral mortality during a widespread marine heatwave. Many Acropora hyacinthus colonies on the shallow reef slope (5 m) were resistant to bleaching, while colonies on the deeper fore reef (14 m) often bleached and subsequently recovered, despite similar thermal …

This study examines how euro area banks factor pollution-induced biodiversity risks into lending decisions, using data from 832 banks and 5,000 major polluters. Our results show that banks are increasingly pricing these risks by adjusting loan-to-value ratios and interest rates. Banks adjust lending conditions in line with EU pollution and biodiversity protection legislation, particularly for companies with large pollution footprints near biodiversity-protected areas or those contributing to Environmental Quality Standards failures of downstream surface waters. The former is driven primarily by banks’ adoption of biodiversity policies and public commitments to the Equator Principles, while the latter is a result of …

In Kenya, climate variability and change threaten smallholder, rainfed farms, with crop failures, yield reductions, and pest infestations. Efficient agroecological strategies, such as Push-Pull intercropping, offer documented benefits including pest control, improved soil fertility, and water conservation compared to traditional maize monocropping. To date, no studies exist comparing traditional maize monocropping and Push-Pull intercropping using earth observation tools over several growing seasons in East Africa. Our research addresses this by harmonizing Landsat 7, 8, 9 with Sentinel-2 remote sensing time series from 2016 to 2023. Phenological metrics of 15 growing seasons are extracted based on a threshold method using the …

Morphometric analysis plays a crucial role in the accurate identification and classification of insect pests, which is essential for implementing effective management strategies. The Asian citrus psyllid (Diaphorina citri Kuwayama; Hemiptera: Liviidae), an invasive species and a known vector of ‘Candidatus Liberibacter asiaticus’ and ‘Ca. Liberibacter americanus,’ the bacterial pathogens associated with Huanglongbing (HLB), has recently emerged as a pest of concern in Ghana. Despite its significance, little is known about the biological traits of field populations in the region. In this study, we examined morphometric variation in D. citri populations infesting citrus and orange jasmine (Murraya paniculata) across different …

Protected areas in the savannas are key global reserves for biological diversity, including arthropods. Fire and mammal herbivory disrupts the diversity of biological organisms that alternately affects the functioning of the ecosystem. The study presents a global synthesis review of arthropod responses to varying intensities of fires and mammal herbivory in the protected savannas. We hypothesise that the intensity of predetermined fires and mammal herbivory has cascading impacts on abundance, species richness and diversity of terrestrial arthropods in the protected savannas. A minimum selection criteria was used to collate relevant literature from electronic databases of previous studies performed in the …

Advances in next-generation sequencing have allowed the use of DNA obtained from unusual sources for wildlife studies. However, these samples have been used predominantly to sequence mitochondrial DNA for species identification while population genetics analyses have been rare. Since next-generation sequencing allows indiscriminate detection of all DNA fragments in a sample, technically it should be possible to sequence whole genomes of animals from environmental samples. Here we used a blood-feeding insect, tsetse fly, to target whole genome sequences of wild animals. Using pools of flies, we compared the ability to recover genomic data from hosts using the short-read sequencing (Illumina) …

Antioch University Dissertations & Theses
Understanding the spatial distribution of current and future habitat for the Kirtland’s Warbler (Setophaga kirtlandii) and other threatened species is critical for guiding conservation planning in The Bahamas. Our study mapped land cover and impacts of sea level rise across the south-central Bahamian islands, as an initial step to determine suitable areas for Kirtland’s Warblers in the region. We used a Random Forest (RF) classification of multispectral satellite image bands and indices from Landsat and Sentinel-2 image composites to predict land cover. The classification identified tropical dry forest communities (broadleaved, semi-evergreen trees and shrubs known as coppice) as …

ASEAN Journal on Science and Technology for Development
Hydrodynamic cavitation (HC) is considered an energy-efficient process with high potential for utilization in many chemical processes. This study presents a computational fluid dynamics (CFD) analysis of cavitating flow through an orifice with a constant flow area. The Reynolds-Averaged Navier-Stokes (RANS) equations, coupled with turbulence and cavitation models, are employed to capture the complex flow behaviors. The effects of inlet pressures and number of orifice-holes on cavitation behavior are investigated. Result of the numerical simulation is validated with the existing experimental data from the literature. The CFD study revealed that cavitation initiates just behind the inlet edge of the orifice …
Modelling The Impacts Of Recreational Catch-And-Release Variability On Fish Stock Dynamics, Brett Crisafulli
Modelling The Impacts Of Recreational Catch-And-Release Variability On Fish Stock Dynamics, Brett Crisafulli
Theses: Doctorates and Masters
Recreational fisheries often lack sufficient data for robust stock assessments, and post-release mortality (PRM) of discarded fish, particularly demersal species, poses a significant threat to sustainability. Because demersal fish often experience higher PRM (often due to barotrauma and stress), the substantial global interest in their recreational fisheries (e.g., Australia, Gulf of Mexico, Western Baltic Sea) raises conservation concerns. This study employs three distinct modelling approaches, applied to four reef-dwelling demersal species, to support effective recreational fisheries management by addressing data uncertainty, unintended consequences of management changes, and PRM effects. Specifically, this thesis (1) evaluates variability in average weights of recreationally-caught …

Biomass burning is a major driver of air pollution and climate-related impacts in Thailand, but a national-level synthesis of research efforts is lacking. This study conducts a comprehensive bibliometric and qualitative review of 256 peer-reviewed publications from 1997–2024, using Scopus-indexeddata to explore research trends, thematic patterns, and existing gaps. The analysis reveals a strong emphasis on atmospheric chemistry, air quality modeling, and remote sensing, which collectively account for more than 60% of the research landscape.Studies frequently focus on pollutants such as PM2.5,PAHs, carbon monoxide, and heavy metals, with biomass burning identified as a dominant source, especiallyduring the dry season in …

The biodiversity status measures the ecological capacity of a given area. However, biodiversity assessments in developing countries are limited by the absence of taxonomic data on plants and animals. By developing methods to evaluate biodiversity via alternative data, it is now possible to quantify the ecological carrying capacity in areas where taxonomic data are lacking. The relationship between forest ecosystem health and biodiversity values can be used to estimate biodiversity values by considering the proportions of different land use types that are associated with forest ecosystem abundance. The biodiversity value of the area can be assessed by adding the abundance …
