Unruly And Unresolved: A Shared, Precarious Survival, Sara Inacio

Masters Theses

I'm just a little rat trying to survive,

To exist and not be perceived.

Building a home,

In a place unnatural to me.

Destroyed and rebuilt again,

I've learned to live in the toxic world you've created.

In a world that is not made for my belonging, I’ve had to find my way, to exist and build with what’s within reach. Such a constant state of construction feels oddly familiar and comfortable to me, home is always in the process of becoming. As I build, I think about how the home building process always takes up the space of others, …

Endless Form, Kaela Kennedy

Masters Theses

Endless Form is a gentle argument for a practice rooted in embodied seeing and communicating. It invites the reader through multiple actions of visual and linguistic perception – observation, seeing, and attention – and examines how these methods operate to widen our fields of understanding to more empathetically engage with the world as an ecological whole. It claims that graphic design, as a practice built on the relationship between visual form and language, has a unique ability to translate the unending feedback loop between the eye, the seen, and the language we use to define it. It argues for ways …

The findings of this study reveal that children exhibit high levels of enthusiasm …

Designing A Serious Game To Simulate Ecological Processes On A Post-Eruption Mount St. Helens Landscape, Parker Maynard

Masters Theses

Developing strategies to successfully manage landscapes to meet ecological, economic, and social goals is an increasing concern in a world experiencing anthropogenic global changes. The 1980 eruption of Mount St. Helens in Washington state provided a major learning opportunity in managing resource effectively after a major disturbance. This information is explored through Resilience: After The Eruption: a serious game developed as part of this thesis that synthesizes research about ecological recovery and resource management following the eruption of Mount St. Helens. The digital game allows players to take on the role of four different stakeholders performing landscape-based operations while …

Evaluation Of Avian Use Of Agricultural Cover Crops During The Winter, Migration Stopover, And The Breeding Season In Tennessee, Brittany Panos

Masters Theses

The U.S. Department of Agriculture Natural Resources Conservation Service administers the cover crop program to provide technical and financial assistance to agricultural producers to sow herbaceous plant seeds to establish cover crops to protect agricultural fields from soil erosion during the non-growing season (late fall through spring). Soil retention and water quality benefits have been documented, but potential benefits for avian wildlife remain largely unknown. I used line-transect avian and vegetation surveys to examine use of cover crop fields by birds during the non-breeding period (winter), migration, and the breeding season. I compared avian use of cover crop fields with …

A Comparative Study Of Biocrusts On Gypsum And Non-Gypsum Soils In The Northern Chihuahuan And Eastern Mojave Deserts, Usa: Biocrust Mosses Respond To Soil, Environmental, And Climatic Conditions, Katelyn Gobbie

Masters Theses

Biological soil crust communities (biocrusts) growing on gypsum soils have been well- documented for their prolific appearance and rich diversity of lichens and bryophytes. However, studies characterizing gypsum biocrusts have primarily occurred outside of the U.S., most of which lack comparisons to other soil types. We conducted intensive field surveys to evaluate the cover and frequency of biocrust functional groups and moss species on gypsum and non-gypsum soils in the U.S. regions with the most extensive gypsum outcrops, the northern Chihuahuan and eastern Mojave Deserts. We employed canonical correspondence analysis (CCA) to relate the observed differences in biocrust abundance and …

To Melt, Huanzhe Hu

Masters Theses

This thesis focuses on the need for a reevaluation of the relationship between humans and nature in the face of the current ecological crisis. The author argues that the dominant anthropocentric orientation, which sees nature as a resource to be exploited for human benefit, has led to over extraction and resource abuse, disrupting the balance of ecosystems. Instead, the author suggests adopting an ethical framework based on mutual understanding and appreciation, breaking the "hunter's gaze" and fostering empathy for non-human life forms. This thesis also explores the potential for new forms of communication and engagement with nature, such as through …

Toronto Rewilded, Forrest Meyer

Masters Theses

Global urbanism has left almost no room for native ecology, this has an adverse effect on biodiversity, so adverse that biodiversity has been lost at an alarming rate globally, accounting for between 50-70% of species eradication. Having witnessed firsthand on the land I grew up on, the immense positives of native plantings on the creation of biodiversity, I am eager to implement native plantings in an architectural thesis. Not only is this important to flora and fauna, and the environment, but also for the biophilic connection humans crave with their environs. The reintroduction and preservation of native plantings, species, and …

Green Paths - On The Space In-Between Buildings, Hongru Zhang

Masters Theses

This project focuses on the “leftovers” of our urban space after carving out what was required for buildings and transportation, and reintegrating them into a network that can be the habitat and paths for pollinators and small animals.

This network overlaps and interacts with our existing urban structures. Integrating it into our life will undermine the hierarchy of space and commodification of land intensified by the existing grid systems of the city, and introduce a different understanding of coexistence with nature.

Miles And Miles And Miles, Shannon Rose Jones

Masters Theses

miles and miles and miles is a body of work that draws design inspiration from the Driftless Area of Wisconsin, a region unflattened by ice during the last ice age. The works are site specific extrapolations that have been abstracted in order to trigger a process of memory recollection in the viewer. Selections of atmospheric prose, furniture objects, illustrations, and imagery are presented as snapshots of a place in an attempt to memorialize and make tangible ephemeral memories collected by the maker traveling in this vast landscape. Attention is given to the distillation of form in order to contemplate its …

Evaluating The Ecological Relationships Among Beauveria Bassiana, Kudzu Bug And Kudzu, Kassie L. Hollabaugh

Masters Theses

When kudzu bug, Megacopta cribraria, was identified in the United States in 2009 as an invasive species, populations began to establish, increase, and spread throughout the southeastern region at intense rates. Kudzu bug invades urban structures, causing unpleasant scenes for homeowners, and reduces crop yield, such as soybean. Kudzu bug caused about $2.8 million in soybean yield loss and treatment in Tennessee in 2020. Although initial spread was rapid throughout the southeastern U.S., spatial modeling has shown populations of kudzu bug are declining and reducing risk of crop damage to growers. These local and regional declines in populations appear …

Geographic Range Size As A Predictor Of Dispersal-Dependent Behavioral Traits In Two Clades Of A Terrestrial Salamander, Teah Evers

Masters Theses

Animal movement has the potential to affect diverse processes within ecology and evolution including range expansion, gene flow, adaptation, and speciation. Two aspects of animal personality that are germane to dispersal are exploratory and aggressive behavior. These behavioral categories may represent a trade-off such that energy invested in territorial defense leaves little energy for movement and dispersal. The Eastern Red-backed Salamander (Plethodon cinereus) is a wide ranging, dispersal limited, terrestrial salamander with well documented phylogeographic divisions. I examined dispersal-relevant behavioral traits within two clades of P. cinereus with disparate geographic ranges. The Northern Clade (NC) has a range extending from …

Investigating The Ecology And Behavior Of The Indiana Bat And Tri-Colored Bat During Fall Swarming And Spring Staging, Mallory E. Tate

Masters Theses

White-nose syndrome has devastated bat populations across North America since 2005. Due to declines in Indiana bat (Myotis sodalis) and tri-colored bat (Perimyotis subflavus) populations across the eastern United States, management prescriptions need to consider all seasons of these species annual cycles. However, data is severely lacking on the two seasons surrounding winter hibernation. These include fall swarming, a time period when bats are mating and preparing for hibernation, and spring staging, when bats are emerging from hibernation and preparing for spring migration. Both periods are critical for successful reproduction and survival following white-nose syndrome infection. …

Carbon Sequestration In A Restored West Michigan Oak Savanna: Implications For Management Practices, Jeffrey A. Heise

Masters Theses

The savanna system is an ecosystem (i.e. a transitional ecosystem) that lies between forest and grassland ecosystems. They occur across the world in various forms, but in the North American Midwest they are specifically oak savannas: systems where the open overstory is dominated by various species of oak (Quercus spp.) and the understory consists of carbon-rich prairie grasses and forbs. This ecosystem is a highly degraded ecosystem and has lost almost 99% of its former range due to agriculture and fire suppression. Since savannas are fire-evolved systems, they are maintained by and require fire as a regular disturbance to …

To Make Atmosphere, Gonzalo Galetto

Masters Theses

My artistic practice explores the possibility of shifting anthropocentric perspectives through media installations. These perspectives exist in the positions we hold in relation to the environment: they continue to exteriorize and distance humans from the environment. To reorient our attention in its direction, and the other-than-human life forms that sustain it, is a social imperative of our times. Reevaluating our engagement with the other, meaning other beings or selves, including other-than-human selves and landscapes, is to readjust our relationship with the environment. It is a way to reposition how to be and to act in the world, but to do …

Blueridgelivin' : Environmental Development And Suburban Sprawl, Chris Villalta

Masters Theses

This thesis focuses on investigating how precolonial Blue Ridge Cherokee construction was resilient to time and weather, integrated place, and respected the environment, traditions, and politics, to better integrate landscape, climate, ecology, and regionally specific architecture.

Urban Ecotone: Restoring The Water-Land Balance As A Strategy For Social Equity, Yuzhe Ma

Masters Theses

This thesis focuses on Dhaka, Bangladesh, and the urban interface between the more formal developed parts of the city and the less-formal and more economically-vulnerable urban neighborhoods.

It seeks to reframe this interface as an ‘ecotone’ versus a hard boundary. By reframing this area along ecological lines, this interface is positioned as a place with a great diversity of ‘species’ and fertile conditions and collisions, which allow it to act as a generator of new opportunities benefitting both of the communities (biomes) which transition into it.

This ecotone is seen as being further fed by the presence of urban ecology …

Is Context Dependency Imperative To Understanding The Impacts Of Invasive Plants?, Brendan B. Haile

Masters Theses

Introduced exotic species have a tendency to become invasive and impact local biological communities. Invasions often impact community attributes such as cover and species richness, but these factors may also regulate patterns of invasion. In such cases, impacts may be dependent on the invasion context. We used data from the Buell-Small Succession Study, a long-term permanent plot study in the piedmont region of New Jersey, to document context dependency in invasion. To do this, we analyzed the factors that affected the colonization and growth of four invasive species, Alliaria petiolata, Lonicera japonica, Microstegium vimineum and Rosa multiflora, as well …

Patterns Of Morphological Plasticity In Metriaclima Zebra And Danio Rerio Suggest Differently Canalized Phenotypes Due To Form-Function Relationships, Dylan Jockel

Masters Theses

In order to ascertain the degree of compatibility in developmental restructuring and behavioral plasticity between two fish species frequently made subject of laboratory research (Metriaclima zebra & Danio rerio), alternative trophic niche exposure experiments utilizing novel three-prong feeding treatments were conducted to obtain morphometric data, which demonstrated both species do bear some degree of plasticity. The results are somewhat complicated by differences in locality of detectable restructuring, which may be due to disparity in the form-function relationship for each species’ lineage. Each is notable in the manner of respective species’ jaw protrusion, as it is driven by anterior …

Improving Identification Methods For Tabanus Flies (Diptera: Tabanidae) From The Southeastern United States Using Dna Barcoding & Environmental Niche Modeling, Travis Davis

Masters Theses

Blood-feeding female horse flies (Diptera: Tabanidae: Tabanus) are pests of livestock and man worldwide. Direct damage from Tabanus blood-feeding results in blood loss and physical damage to the skin. Indirect outcomes are the potential transmission of pathogens, economic losses in livestock production, and disruption of outdoor recreation. Horse flies are an understudied group and Tabanus classification remains incompletely resolved due to variable morphological characters, high diversity, and limited research within the group. Therefore, the first step to evaluating horse flies as pests is improving identification methods. Our overarching goal was to improve methods of Tabanus identification by building a DNA …

Athletes’ Perceptions Of Their High School Sport Ecology And Life Skills Development, Kylee Jo Ault

Masters Theses

Sport psychology researchers have examined the degree to which youth sport participation leads to positive developmental outcomes. Contemporary findings suggest that these outcomes are more likely to occur when adults intentionally design environments that foster life skills development. However, many of these studies have only examined one adult relationship (e.g. Camiré, Trudel, & Bernard, 2013; Gould, Collins, Lauer, & Chung, 2007; Turnnidge, Côté, & Hancock, 2014) without acknowledging the larger context surrounding interscholastic sport. The purpose of this study was to examine high school student-athletes’ perceptions of how stakeholders in their high school sport-ecosystem influence their life skills development and …

Plasticity And Biotic Interactions Mediate Plant Persistence In A Changing World, Alix Ann Pfennigwerth

Masters Theses

Anthropogenic global change is occurring today at a faster rate and larger scale than ever before. Understanding how plants will respond to such large-scale disturbance is critical for biodiversity conservation, yet the ecological and evolutionary mechanisms underlying these responses remain poorly understood. In this thesis, I investigated the mechanisms underlying plant response to two major drivers of global change, climate change and the widespread mortality of foundation species. First, I examined genetic and plastic plant trait responses to climatic variation using elevation gradients, which serve as space-for-time substitutions for climate change. Through field observations in three populations of the North …

Reconnecting The Urban Web: Chicago's Failed Olympic Hope, Eric Archer

Masters Theses

‘Towers in the park,’ a destructive urbanistic typology that gained notoriety with idealistic projects by Le Corbusier, are prevalent in American cities. This architectural and urban concept consists of mono-functional high-rise towers, typically residential, placed on a superblock of unprogrammed over-scaled greenspace. The original intention was to create order within the city and provide plenty of landscaping and urban space for the city’s occupants. Noble in goals, these mega-towers have been chastised for their lack of character, inappropriate scale, and the inability to create vibrant public space that promote interaction and community by creating an over concentration of segregated nodes …

Environmental Constraints On Cyanomyophage Abundance In The Subtropical Pacific Ocean, Tiana Maria Pimentel

Masters Theses

Viruses are abundant in the world’s oceans and are thought to be important participants in marine biogeochemical cycling. Of these viruses, cyanophages are considered especially important because they infect and lyse cyanobacteria, which are some of the main primary producers in marine environments. Cyanophages are thought to influence the abundance and diversity of cyanobacterial populations and impart significant mortality, thereby affecting primary productivity and microbial community structure. Despite their ecological relevance, little is known about how environmental factors shape cyanophage abundance and diversity over large temporal and spatial scales. To address this gap in knowledge, seawater samples were collected during …

Creating Sustainable Economic And Ecological Growth In The Congo Basin: Bushmeat Consumption And Biodiversity Protection, Richelle Lynn Warnock

Masters Theses

This research examines the economic and ecological sustainability of bushmeat hunting in the Congo Basin, specifically the Democratic Republic of Congo and the Republic of Congo. Although bushmeat hunting has provided short term gain for individuals in the region, long term solutions focusing on micro and macro level interventions may provide community wide benefits, while protecting Congo Basin wildlife. Research shows that a focus on the development of key economic sectors such as agriculture, mineral resources and hydroelectricity, as well as the growth of infrastructure may provide viable economic gain for the Congo Basin. Ecotourism and improvements to forest management …
