Place, Space, And Shifting Views Of Nature, Rachel Tracey
Place, Space, And Shifting Views Of Nature, Rachel Tracey
Runkle Woods Symposia
In her reflective presentation, Rachel Tracy explores her evolving relationship with nature and wilderness. Initially disinterested and uncomfortable in natural settings, she describes how her perspective shifted through class discussions, personal reflection, and immersive experiences in the outdoors. Concepts such as “space versus place” helped her understand the emotional and historical significance of natural environments. Through this journey, she discovered joy in simply being present in nature, ultimately gaining a deeper appreciation for the natural world and its ability to exist and thrive without human involvement.
Culture, Nature, And Reflection: The Settler’S Impact On Life Today, Erin Thomas
Culture, Nature, And Reflection: The Settler’S Impact On Life Today, Erin Thomas
Runkle Woods Symposia
Erin Thomas, a senior English major at Wright State University, reflects on the intersection of wilderness, identity, and cultural erasure. Drawing from her Indigenous heritage and experiences in the course Woods and Wilderness, she critiques the romanticized, Eurocentric view of nature as untouched and separate from humanity. Instead, Thomas highlights how wilderness has been shaped by settler colonialism and exclusionary narratives that often ignore Indigenous presence and histories. Her presentation calls for a more inclusive and honest understanding of wilderness—one that honors marginalized voices and acknowledges the land’s complex cultural past.
Wilderness Myth And Reality: Human Views And Uses Of Nature, Evan Hardern
Wilderness Myth And Reality: Human Views And Uses Of Nature, Evan Hardern
Runkle Woods Symposia
In his essay and presentation, Wright State English major Evan Harder critically examines modern conceptions of wilderness and challenges the Romantic ideal that moral purity and personal virtue are inherently tied to time spent in nature. Drawing on writers such as Wordsworth, Emerson, and Thoreau, Harder interrogates the cultural myth of wilderness as a pristine, untouched realm separate from civilization. He argues that our understanding of nature is a constructed concept—born from the development of cities and agriculture—and often overlooks the long histories of human habitation in places now designated as “natural” or “wild.” Through examples like Cuyahoga Valley National …
The Concept Of Wilderness In Western Culture And Its Sacredness, Shannon Doyal
The Concept Of Wilderness In Western Culture And Its Sacredness, Shannon Doyal
Runkle Woods Symposia
Shannon Doyal, a Professional Writing student at Wright State, explores how wilderness has been perceived throughout American history—as both a physical space and a powerful spiritual symbol. Drawing from Indigenous perspectives, early settler narratives, Transcendentalist writings, and American literature, she traces the evolving cultural and emotional significance of wilderness. From a place of fear and survival to one of introspection and sacred connection, wilderness reflects our changing relationship with nature and ourselves. As someone whose spirituality honors the cycles of nature, Doyal argues that reclaiming wilderness as a sacred and emotional space is vital—not only for environmental preservation but also …
Endangered Bats In The Runkle Woods, Volker Bahn
Endangered Bats In The Runkle Woods, Volker Bahn
Runkle Woods Symposia
Since 2019, Dr. Volker Bahn’s lab has been monitoring bat populations in the Runkle Woods and nearby sites, using acoustic detectors to track species presence and activity over time. With bats representing about 20% of all mammal species globally, their ecological role—particularly in insect control—is vital. The presentation highlights the diversity of local bat species, with 10 of Ohio's 11 expected species documented, ranging from the abundant big brown and red bats to the federally endangered Indiana and northern long-eared bats. Dr. Bahn discusses patterns in bat activity across years, potential drivers such as precipitation, and the concerning declines in …

Water Quality Management In The Runkle Woods, Krystal Demarco, Donavon Mishler-Laporte, Cassie Dunn, Parneet Dhillon, Reagan Hardyman
Runkle Woods Symposia
This project addresses the growing issue of salt pollution in Wright State Woods, with a specific focus on sodium chloride runoff from deicing agents. Elevated salt levels, stemming from university parking lots and surrounding infrastructure, have been linked to soil degradation, vegetation stress, and aquatic habitat damage. By analyzing salt flow patterns and assessing ecological impacts, including EPA-reported chloride violations, the team identified critical areas of concern such as Outfall #2. Proposed mitigation strategies include the use of salt-tolerant tree species, alternative deicers (e.g., acetate- or carbohydrate-based), physical barriers, and expanded retention ponds and filter dams.
Invertebrates As Indicators Of Water Quality In The Runkle Woods, Dillynn Blevins, Bhavishya Ratnavelu, Lauren Stetz, Corey Walls
Invertebrates As Indicators Of Water Quality In The Runkle Woods, Dillynn Blevins, Bhavishya Ratnavelu, Lauren Stetz, Corey Walls
Runkle Woods Symposia
This project investigates water quality and aquatic invertebrate habitat health in the Wright State Woods, aiming to assess current conditions and implement targeted conservation strategies. Using indicators such as dissolved oxygen, nutrient concentrations, and the presence of sensitive macroinvertebrates (e.g., mayflies, stoneflies, caddisflies), the team evaluates stream health. Data collection follows established protocols, including EPT indexing and seasonal surveys. Conservation recommendations include stream aeration maintenance, removal of non-native vegetation, soil inoculation, and the construction of rain gardens and green roofs to reduce runoff.
An Accessible Trail For The Runkle Woods, Sarah Bingham, Terri Dozier, Logan Huber, Nicole Owino, Nathan Shafer
An Accessible Trail For The Runkle Woods, Sarah Bingham, Terri Dozier, Logan Huber, Nicole Owino, Nathan Shafer
Runkle Woods Symposia
This presentation outlines a student-led initiative to enhance a pre-existing trail in the Runkle Woods with educational conservation projects and signage. The project aims to increase accessibility and student engagement with Wright State’s natural areas. Three key conservation efforts are highlighted along the trail: prairie restoration to support native biodiversity and pollinators, erosion and runoff mitigation using native vegetation and riff-raff, and bat conservation through habitat preservation and installation of artificial roosts. The project emphasizes experiential learning, sustainability, and community involvement in environmental stewardship.
Management Of The Invasive Honeysuckle (Lonicera Maackii), Mesa Grine, Daniel Hazelett, Cassie Healy, Padma Deepika Kandregula
Management Of The Invasive Honeysuckle (Lonicera Maackii), Mesa Grine, Daniel Hazelett, Cassie Healy, Padma Deepika Kandregula
Runkle Woods Symposia
This presentation addresses the ecological threat posed by invasive honeysuckle in the Runkle Woods on Wright State's campus. Originally from Europe and Asia, honeysuckle aggressively outcompetes native flora due to its rapid growth, shade tolerance, and allelopathic properties. The students observed widespread honeysuckle in both new and old growth forest areas, with greater density in younger regions. Ineffective control methods—such as cutting without herbicide—often worsen infestations. Drawing on a regional study, the students propose a targeted management plan involving cutting and herbicide application, stem injection for larger plants, and reintroducing native species like spicebush. Their strategy aims to reduce honeysuckle …
Old Growth In The Runkle Woods, Madeline Greene, Lindsay Smith, Matt Tyren, Leif Walters
Old Growth In The Runkle Woods, Madeline Greene, Lindsay Smith, Matt Tyren, Leif Walters
Runkle Woods Symposia
In this conservation proposal, Wright State students focus on protecting the old growth areas of Runkle Woods—a rare and ecologically significant habitat in the Eastern United States, where only about 1% of such forests remain. Home to trees over 200 years old and critical species like endangered bats and white oaks, this 100-acre area faces threats from invasive species, deer overpopulation, littering, and urban runoff. Currently, only 15 acres are legally protected. The students propose expanding the easement, involving experts and graduate students in ongoing research and stewardship, and increasing public engagement through educational walks and increased and updated signage. …
Up In Smoke: Indigenous Techniques To Combat Climate Change And Increase Biodiversity, Brad Kerry
Up In Smoke: Indigenous Techniques To Combat Climate Change And Increase Biodiversity, Brad Kerry
Runkle Woods Symposia
Brad Kerry explores how Indigenous land management practices—particularly the use of prescribed fire—can be reintroduced to restore the Runkle Woods to its pre-colonial ecological state. Drawing on archaeological evidence, historical tree surveys, and ecological data, the presentation highlights how periodic, low-intensity fires historically maintained the forest’s biodiversity, promoted fire-adapted species like oak and hickory, and suppressed invasive plants. Kerry advocates for carefully planned, small-scale burns to combat "mesophication"—a shift toward shade-tolerant, fire-averse species—while increasing forest resilience to drought, invasive species, and climate change. The presentation underscores the ecological benefits of fire and outlines practical considerations for reintroducing controlled burns as …

Tecumseh Land Trust: Land Trusts And Land Preservation, Michele Burns
Runkle Woods Symposia
Part 1 of the "Protecting Glen Helen with a Conservation Easement" presentation. Michele Burns introduces the concept of land trusts—nonprofit organizations that protect various types of land, particularly through conservation easements, which are legally binding agreements that restrict development and preserve land forever. She explaines how Tecumseh Land Trust, founded in 1990, operates in southwest Ohio to protect farmland and natural areas without owning land directly and their work in protecting the Glen Helen preservation.

Human Impacts On Mammal Diversity From The Pleistocene To The Present, Carson P. Hedberg
Human Impacts On Mammal Diversity From The Pleistocene To The Present, Carson P. Hedberg
Biology ETDs
Humans have fundamentally altered the planet’s biodiversity. It is critical to characterize these changes, but also to understand how they impact the structure and function of modern ecosystems. This dissertation investigates how anthropogenically mediated species losses and/or introductions influence ecological function and community structure in mammals across multiple temporal and spatial scales. We found that selective loss of large-bodied mammals over the Late Quaternary has led to severe losses in functional diversity in modern ecosystems, suggesting megafaunal mammals contribute distinct ecological functions. These changes to mammal diversity and distribution over millennia have altered both global patterns in functional diversity and …

Multi-Decadal Aspen Dynamics Show Recruitment Bottleneck Across Complex Mountain Community, Michael T. Stoddard, Kyle C. Rodman, Connor D. Crouch, David W. Huffman, Peter Z. Fulé, Kristen M. Waring, Margaret M. Moore
Aspen Bibliography
Changes in forest structure and shifts in tree species composition have occurred globally due to climate change and altered disturbance regimes. With climate trending toward warmer and drier conditions, these altered forest communities may reorganize in diverse and unpredictable ways. This is especially true in mountain environments where a range of vegetation types and abiotic conditions coexist. In this study, we used long-term permanent plot data from a site spanning broad environmental gradients to assess regeneration and mortality patterns in populations of aspen (Populus tremuloides). The study site, located on the San Francisco Peaks, Arizona, USA, is near …
Spatiotemporal Dynamics Of Coastal Nekton Metacommunities In The Western Atlantic, Jonathan A. Peake
Spatiotemporal Dynamics Of Coastal Nekton Metacommunities In The Western Atlantic, Jonathan A. Peake
USF Tampa Graduate Theses and Dissertations
The processes of diversification, selection, dispersal, and stochastic drift can combine in many ways to assemble ecological communities. A key focus in ecology is to describe and quantify the relative influences of these processes for different systems and explain the mechanisms by which these processes produce patterns of community structure. To accomplish this goal, ecologists have developed several frameworks that seek to integrate processes that occur locally andregionally. The metacommunity concept treats local communities as pieces of a broader landscape that are connected through dispersal of their constituent organisms. Empirical studies have generally lagged behind the development of metacommunity theory. …

Alabama Agricultural Producers’ Experiences With Wild Pigs (Sus Scrofa) And Their Preferences Concerning Wild Pig Management, Hailey E. Ellis, Luren M. Jaebker, Alan D. Bright, Mark D. Smith, Keith M. Carlisle
United States Department of Agriculture Wildlife Services: Staff Publications
Government agencies and landowners use a variety of lethal methods to reduce invasive wild pig populations and resulting agricultural damages. To provide decision-makers with information regarding Alabama farmers’ experiences with wild pigs and their preferences for management actions, we surveyed Alabama Farmers Federation members in 2020. We found that wild pigs were commonly present on livestock, timber, and crop production acreage, but wild pig damages and costs were much more common among crop producers. Respondents' wildlife acceptance capacity for wild pigs was low and all lethal control methods were considered aceptable by most reposndents, particularly those performed by landowners. While …

Transitions Into Freezing Environments Linked With Shifts In Phylogenetic Integration Between Vitaceae Leaf Traits, Charles Tomo Parins-Fukuchi, Gregory W. Stull, Jun Wen, Jeremy M. Beaulieu
Biological Sciences Faculty Publications and Presentations
Understanding how the intrinsic ability of populations and species to meet shifting selective demands shapes evolutionary patterns over both short and long timescales is a major question in biology. One major axis of evolutionary flexibility can be measured by phenotypic integration and modularity. The strength, scale, and structure of integration may constrain or catalyze evolution in the face of new selective pressures. We analyze a dataset of seven leaf measurements across Vitaceae to examine how correlations in trait divergence are linked to transitions between freezing and nonfreezing habitats. We assess this by applying a custom algorithm to compare the timing …
To Be Conscious Or Not To Be, Bjørn Grinde
To Be Conscious Or Not To Be, Bjørn Grinde
Animal Sentience
Carolyn Ristau has done a fine job summarizing the work and life of the zoologist Donald Griffin. Most scientists now accept the existence of animal sentience, but identifying which species possess consciousness remains controversial. Griffin defined consciousness as "the subjective state of feeling or thinking about objects and events.” Nonconscious processes are faster and more energy-efficient, however, and often drive behavior. Consciousness probably evolved for complex decision-making, shaped by evolutionary continuity, with feelings as a common currency for evaluating outcomes. Its survival advantage may be limited, and its presence across species varies depending on evolutionary trajectories.

Euscorpius
A new species Tityopsis rolandoi sp. n. is described from Cuba, fully illustrated with color photos showing its morphology and habitus. T. rolandoi sp. n. is the only species of the genus with a combination of two characters: movable finger shorter than carapace and chela length/width ratio 3.6 in male. This species also has a characteristic shape of a median smooth patch of sternite V, which is almost oval in male. In addition to morphology, we present the information about the karyotype of T. rolandoi sp. n. (2n=20) and T. sheylae (2n=22).

Communication In Noise Is The Window On Cognition, R. Haven Wiley
Communication In Noise Is The Window On Cognition, R. Haven Wiley
Animal Sentience
As Griffin surmised, communication is the window on cognition, but as shown here, only if it is noisy. This commentary is an invitation to consider the full implications of the evolution of noisy communication. A combination of Information Theory, Signal Detection Theory, and Natural Selection, in a unified theory of the evolution of communication, reveals that noise is inevitable. All organisms are thus decision makers. Perception, thought, freedom of decision, self-awareness, metabolism, and natural selection all share the consequences of signals in noise. A full understanding of each requires attention to the errors of receivers. Griffin’s hunch is correct with …
