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

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

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

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

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

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

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

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

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

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 …

This presentation offers an overview of Glen Helen, a 1,125-acre private nature preserve in Yellow Springs, Ohio, detailing its ecological significance, educational mission, and recent conservation efforts. Nick Boutis describes the preserve’s history, from ancient Indigenous use to its development as a resort and eventual donation to Antioch College. The focus centers on the complex, multi-year collaboration that led to establishing a permanent conservation easement, which now protects the land from development and subdivision. The presentation also highlights Glen Helen’s ongoing stewardship work, including habitat restoration, environmental education, …

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.

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 …

Habitat Preferences Of The Hiwassee Crayfish (Cambarus Hiwasseensis) And Appalachian Brook Crayfish (Cambarus Bartonii Cavatus) In A Headwater Stream, Johnathan G. Davis

Georgia Journal of Science

The Hiwassee crayfish Cambarus hiwasseensis (CH) is an endemic species to the Hiwassee River watershed in north Georgia and western North Carolina that is sympatric with the more widespread Appalachian Brook crayfish Cambarus bartonii cavatus (CB). This was the first study to investigate CH habitat use, comparing CH habitat to CB habitat in Corn Creek, a small, second-order stream in the Hiwassee River watershed. From August to November 2016 and January to April 2018, 15 habitat parameters were measured for 154 1-m² quadrants randomly sampled from an 800-m stream reach. Mann-Whitney U tests compared habitat parameters between present and …

Understanding The Welfare Of Aquarium Fish, Paul Rose

Animal Sentience

Bony fishes (Osteichthyes) are prevalent in public and domestic aquaria, yet evidence-based welfare practices exist for only a limited number of species. Oldfield & Bonano’s (O&B’s) target article highlights critical questions about the wellbeing and sociality of Osteichthyes. Advancing research on their biology, physiology, psychology, and behavior is essential to develop and validate welfare measures, ensuring guidelines for welfare-focused housing and husbandry.

Notes On North American Butterflies, 2, Harry Pavulaan, Janice E. Arndt

The Taxonomic Report of the International Lepidoptera Survey

New natural history elements and distribution records of several North American butterflies are reported. While diversity and distribution of butterflies in North America are commonly believed to be fully known, the findings presented here show that much is yet to be learned of our butterfly fauna.

Can We Use Judgement Bias To Assess The Welfare Of Fish In Aquariums And Zoos?, Culum Brown

Animal Sentience

This commentary examines the potential of tests of judgment bias to assess fish welfare in aquariums and zoos. Judgment bias offers a non-invasive approach to interpreting affective states in animals, using cognitive responses to ambiguous stimuli as indicators of mental wellbeing. Despite the constraints of captive environments—such as limited handling and species diversity in exhibits—recent adaptations of judgment-bias protocols make them suitable across taxa, including fishes. Collaborations with progressive zoos and aquariums could facilitate this research, based on the shared goal of enhancing animal welfare and promoting public education.

Pengaruh Larangan Ekspor Karang Hias Terhadap Kondisi Terumbu Karang Di Indonesia, Fitrian Dwi Cahyo, Muhammad Halley Yudhistira

Jurnal Kebijakan Ekonomi

Indonesia has the largest coral population in the world, contributed as the world’s second largest ornamental corals exporter after Japan. Coral trade sparked the issues of habitat destruction, illegal trade, and coral health problems has prompted the government to banning of ornamental coral export. This study aims to find an empirical evidence does the policies mentioned above affect the condition of coral reefs in Indonesia. The author uses the Fixed-Effect Model on the Difference in Difference regression equation whose result show that export banning of ornamental corals does not significantly affect the condition of coral reefs in Indonesia.

Determination Of A New Spring-Flying Species Of The Pterourus Glaucus Complex (Papilionidae) In Southern New England, Harry Pavulaan

The Taxonomic Report of the International Lepidoptera Survey

The Pterourus glaucus complex in three southern New England states is analyzed for cryptic speciation. What was historically considered to be one species, P. glaucus (Linnaeus, 1758), was recently split to separate P. canadensis (Rothschild & Jordan, 1906) at species rank (Hagen et al., 1991). Additionally, P. appalachiensis Pavulaan & Wright, 2002, was described as an Appalachian Mountain endemic. The western member of the complex, P. rutulus (Lucas, 1852), has frequently been considered a subspecies of P. glaucus (Scott, 1986; Tyler, Brown & Wilson, 1994), as was P. alexiares (Höpffer, 1866) (Tyler, Brown & …

Working In Pairs Increases Consistency Of Georgia Adopt-A-Stream's Habitat Assessment, Christopher H. Kodani, Robert Bourne, Cody Jones, Michael Kahle, Cecilia Nachtmann

Georgia Journal of Science

Habitat assessment is a skill that is important to stream ecologists of all levels, including volunteers of water quality monitoring programs such as Georgia Adopt-A-Stream (AAS). Some aspects of habitat assessment can be subjective because observers must use their best judgement in assessing some variables, therefore, it is worthwhile to examine the variation in volunteer stream monitor observations, the effect of training, and the reliability of habitat metrics calculated from the data collected. To gain some insight, we asked volunteers attending a workshop at AAS’s 2022 Confluence Conference to complete a Habitat Assessment Worksheet both before and after a short …

This piece was inspired by the livestreams of the Monterey Bay Aquarium that film these moon jellies (Aurelia aurita) in their tank. The Moon Jelly is an ink drawing created as part of a collection focused on Monterey Bay Aquarium animals. Through this artwork I hoped to draw attention to smaller marine animals that may otherwise be overlooked even though they provide a vital role in the ecosystem. Moon jellyfish are important marine …

Fire And Ant Interactions Mediated By Honeydew And Extrafloral Nectar In An Australian Tropical Savanna, Fernanda M. P. Oliveira, Carlos H. F Silva, Melinda L. Moir, Inara R. Leal, Alan N. Andersen

Natural Resources Research Articles

Fire is a major disturbance affecting ecosystems globally, but its impact on mutualisms has received minimal attention. Here, we use a long-term field experiment to investigate the impact of different fire regimes on globally important ant–honeydew and ant–extrafloral nectar (EFN) mutualistic interactions in an Australian tropical savanna. These interactions provide ants with a key energy source, while their plant and hemipteran hosts receive protection services. We examined ant interactions on species of Eucalyptus (lacking EFNs) and Acacia (with EFNs) in three replicate plots each of burning every 2 and 3 years early in the dry season, burning late in the …

Psychological And Social Well-Being Of Bony Fishes In Zoos And Aquariums, Ronald G. Oldfield, Patrick Bonano

Animal Sentience

Research on the behaviour of animals in zoos has been conducted for decades, and observations have provided information that has improved the psychological and social well-being of animals. However, research on fishes in zoos and aquariums seems to be lacking. Here, we assess the current state of research on fishes in zoos and aquariums by surveying the peer-reviewed literature. Our assessment differs from previous surveys in that we examine the taxonomic classes Chondrichthyes (sharks and rays) and Osteichthyes (bony fishes) separately. Our survey finds that bony fishes have been drastically underrepresented in zoo journals, more drastically than chondrichthyans, revealing an …

Effects Of Microplastic Biofilms On An Anthropogenically Impacted Suburban Lake, Paris M. Velasquez

Masters Theses

Plastics have been observed in every location on the planet, and their prevalence in the environment is due in part to their strong resistance to degradation. Inland lakes are susceptible to plastic pollution by highway runoff, which contains plastic fragments of brake pads, car tires, litter, and road paint. These plastics eventually enter freshwater environments and degrade into microplastics (
