Agrarian Festivals Of India- Embedded Traditional Knowledge About Environment And Ecology Preserved Across Millennia, Lopamudra Maitra

International Journal of Traditional Knowledge

With a prominent agrarian economy, it is important to note the many agrarian festivals from across the nation. These festivals also help to highlight many rites, rituals and folklore, which forms the basic ethos of the celebrations and within the many layers of these are embedded knowledge about environment and ecology, which has been passed down through thousands of centuries. These have also been variously corroborated through archaeological, historical and epigraphical records of ancient India. This paper is an attempt to highlight this historicity of the agrarian festivals of India, which also corresponds to the mainstream festivals from across India, …

1 Billion Birds Lost: Mechanisms Of Window Collisions And Possible Mitigation Strategies At Lawrence University, Shoshana Schmit

Lawrence University Honors Projects

Windows are currently the largest killer of birds on the planet, with an estimated 1 billion birds dying from collisions annually. If birds that hit windows do not die on impact, they may either die elsewhere shortly afterwards, resulting in the number of carcasses at collision sites being a conservative estimate of the actual number of fatalities. During the day, proximity to foraging sites and reflectivity play crucial roles in the danger of windows, and during the night, artificial illumination emitting from windows disorients and inhibits navigational cues. To explore this topic on campus, I documented bird collisions at Lawrence …

Aquatic Interrelations In Malika Mokeddem’S Novel N’Zid (2001), Laura C. Klein

Green Humanities: A Journal of Ecological Thought in Literature, Philosophy & the Arts

This article offers an ecological analysis of Malika Mokeddem's novel N'Zid (2001), moving beyond postcolonial and anthropocentric interpretations. It centers on the protagonist Nora's individuation, arguing this process is intrinsically linked to her evolving relationship with the aquatic environment from which she emerges. The article aims to situate N'Zid within an ecological perspective, particularly relevant in the Anthropocene, an era compelling a reassessment of humanity's place. Echoing Bruno Latour, addressing inter-relationality is essential as the stable physical framework of the Moderns becomes unstable. This view necessitates rethinking environmental issues and encourages a scientific interpretation of the novel, drawing on neurosciences, …

Complexity Theory And Environmental Conservation Management: A Case Study With Coyote And Red Wolf Hybridization, Gretchen E. Mahalic

Honors Undergraduate Theses

Conservation biology and invasion biology are value-led scientific disciplines founded on environmental advocacy, operating at the intersection of research and action. Though these disciplines are known for their scientific veracity, unexamined values are often promulgated without scrutiny and drive decisions that work against good ecological outcomes. A case in point is that coyotes migrating into southeastern territory are framed as the greatest threat to the conservation of the endangered red wolf because hybridization is seen as diminishing their species integrity. Applying Val Plumwood’s ecofeminist account of dualistic frameworks, I will use this case to show how the vilification of the …

Land Use Matters: The Interactions Between Soil Characteristics, Ecosystem Cycling, And Anthropogenic Influences At Valley View Farm, Heidi Nydam

Standard Theses

Soil characteristics are the foundation of forest and agricultural productivity. Therefore, understanding how soils change as a reflection of changing landscapes is essential for sustainable management. Valley View Farm is a small, multi use farm in central southern Maine, which seeks to balance conservation and successful farming in terms of providing for the owner and the surrounding community. There are a variety of management practices across the farm, but three distinct areas were examined: the Older Forest, which has been only minimally managed for the last 100 years; the Newer Forest, which was selectively logged 15 years ago and left …

A Benjaminian Rumination Of Grasses And Tomatoes In Contemporary Anatolian Film, Ceren Izci

Dissertations, Theses, and Capstone Projects

This thesis interprets the intersection of history, ecology, and politics through two contemporary Anatolian films: Nuri Bilge Ceylan’s About Dry Grasses and Murat Fıratoğlu’s One of These Days When Hemme Dies. We focus on the films’ portrayal of social relations and relationships to other living beings through interpreting the temporal layers and historical tensions present in the plots of the films. We introduce the paper by pondering over the question of whether these films are political. Drawing on Walter Benjamin’s concepts of “first nature” and “second nature”, the first chapter introduces the philosophical framework for understanding the connection between …

René Dubos: An Annotated Bibliography, Carol L. Moberg

René Dubos: An Annotated Bibliography

René Dubos (1901–1982), a prominent 20th century scientist, humanist, and philosopher, was a prolific author. Affiliated for more than 50 years with The Rockefeller Institute for Medical Research/The Rockefeller University, his studies ranged from antibiotics and the role of bacteria in human diseases to formulating broad ecological and environmental questions affecting human health and disease. His seminal writings explore a lifelong belief that a living organism—whether microbe, human being, society, or the Earth itself—could be understood only through its relationships with everything else.

This comprehensive bibliography of more than a thousand works by René Dubos includes brief annotations for each …

The Role Of Local Factors In Shaping Microbial Communities And Biogeochemical Functions Across Scales, Alexander Polussa

Yale Graduate School of Arts and Sciences Dissertations

Microorganisms play a vital role in carbon cycling, driving the decomposition and transformation of organic matter (OM) in soils. This dissertation examines how both broad climatic and local factors shape microbial communities and influence organic matter decomposition. Through a combination of microcosm and field experiments, I demonstrate that local conditions like soil moisture, depth and plant identity impact microbial function, although these effects can be masked by broader climatic influences. I also investigate how the ericoid shrub, Kalmia latifolia, differentially affects fungal communities under arbuscular and ectomycorrhizal trees. Finally, integrating results from multiple forest sites in the eastern US, I …

An Analysis Of The Ugandan Media Coverage Of Climate Change Stories: A Case Of Daily Monitor Newspaper And Vision, Joseph Elunya

Master of Arts in Digital Journalism

The study analyzed how the Ugandan media covers climate change, focusing on the case of The New Vision and the Daily Monitor newspapers. Climate change remains one of the most global challenges of our time. Around the world, the environmental consequences of climate change are leading to more intense droughts in some regions while causing flooding in others. As mitigation efforts are being spearheaded at the international stage, the media is playing a very instrumental role in awareness creation. Despite the critical role of the mass media in shaping public opinion and driving policy, the Ugandan media suffers from the …

Mycorrhizal Type Mediates Plant-Soil Feedback And Density Dependence In A Sri Lankan Rainforest, Akshay Surendra

Yale Graduate School of Arts and Sciences Dissertations

How do so many species of trees coexist in a forest? A century of research has discovered multiple mechanisms that could maintain local-scale diversity. Chief among them, at least at early life stages, is a pattern of stronger neighborhood competition from conspecifics than heterospecifics. This pattern is driven, at least in part, by specialized natural enemies such as insects and pathogens that damage host trees more than others. Unsurprisingly, the strength of neighborhood effects varies widely among species and a current avenue of research involves understanding what explains this variation. A major axis of variation that has emerged among trees …

From Individuals To Ecosystems: The Role Of Intraspecific Variation And Phenotypic Plasticity In Ecosystem Function, Nathalie Rose Sommer

Yale Graduate School of Arts and Sciences Dissertations

Understanding how organisms shape ecosystems is a central goal of ecology, particularly in an era of rapid environmental change. While ecosystem models have traditionally emphasized species-level diversity and abiotic controls, this dissertation provides evidence that trait variation within species—driven by phenotypic plasticity and transgenerational effects—can have consequences for ecosystem structure and function. Intraspecific variation is increasingly recognized as a key component of biodiversity-ecosystem function relationships, yet its effects remain underrepresented in empirical studies and predictive frameworks. By integrating multigenerational field experiments, multi-trait assessments, and detailed ecosystem measurements in a long-term, well-characterized study system, this dissertation bridges evolutionary ecology and ecosystem …

Frozen Green Leaves As Potential Nutrient Subsidies In North American Mangrove Ecosystems, Katelyn Overstreet, Emily M. Dangremond, Ilka C. Feller

Biological Sciences Faculty Publications

Avicennia germinans, the black mangrove, has shifted its range limit northward, and increased in abundance in the Southeastern United States. In January 2018, a 3-day freeze event caused substantial defoliation of green leaves in A. germinans near its northernmost range limit in St. Augustine, FL. During their recovery, plants that lost their leaves grew similarly to plants fertilized with nitrogen, leading to the hypothesis that freeze-killed green leaves (frozen green) may have acted as a fertilizer. To assess the value of frozen green litter as a nutrient subsidy, we performed an experiment in which A. germinans seedlings were grown …

Impacts Of Salinity And Drought On Growth And Carbon Sequestration In Acorus Americanus And Carex Scoparia, Eleora L. Mantle

Browse all Theses and Dissertations

From the late 18th century until the 1980s, Ohio lost close to 90% of its wetlands. Despite increased efforts to maintain what is left, many freshwater marshes are still being degraded due to pollutants, such as road salt, and the impacts of climate change. This study sought to understand how both road salt and drought could impact the health and carbon sequestration of two wetland species, Acorus americana and Carex scoparia, to better understand tolerance. To do this, both species were separated into groups and subjected to varying salt concentrations and drought conditions. After 9 weeks of treatment, plants were …

Benthic Algal Biomass And Productivity Across Depth Gradients In Lakes Michigan And Erie, Ahmed Ogidan

Browse all Theses and Dissertations

Benthic primary production is poorly quantified in the Laurentian Great Lakes relative to phytoplankton-based production. We measured benthic chlorophyll and benthic primary productivity on soft sediments and Dreissena shells along depth gradients in Lakes Erie (2024) and Michigan (2025) during EPA Cooperative Science and Monitoring Initiative cruises. We measured benthic chlorophyll fluorometrically and estimated benthic primary productivity using non-invasive oxygen exchange incubations. We used PAM fluorometry to characterize photosynthetic-irradiance relationships on mussel shells and sediments in Lake Michigan. In Lake Erie, sediment chlorophyll ranged from 20 to 150 mg m⁻², with highest values in the central basin. In Lake Michigan, …

Blood On Their Hands: Settler Colonial States In The Arctic, Mer M.

Tapestries: Interwoven voices of local and global identities

The Arctic is currently the most rapidly warming region in the world. Modern-day media has been transfixed by the image of the poor polar bear, eeking out a difficult living as the sea ice they depend on has been melting. What often remains outside of the frame, however, are the more complex questions about how we got to this point of extreme climate change. Linking the genocidal histories of Indigenous assimilation in the Arctic to the modern-day ecological crises plaguing the region introduces the state as an overlooked climate polluter. While Arctic communities are all on the frontlines of climate …

In Kinship With The World: Developing A Novel Instrument To Assess Human-Nature Relational Values, Kimberly Post

Educational Studies Dissertations

In the nascent field of human-nature relational values, there is a growing body of literature suggesting their transformative potential in sustainability education. The ability to analytically distinguish relational values from other valuations can both inform pedagogical approaches and help to identify how people understand and value their relationships with the living and more-than-living biospheric inhabitants. To address this need, an overarching question was posited: Can a relational values-specific assessment instrument be designed and validated for use in post-secondary sustainability education? Through a survey of the literature, thematic analysis of validated human-nature connection instruments, and multi-method qualitative research, a pilot instrument …

Cosmic Partnership: Hildegard Of Bingen’S Vision Of An Integral Ecology, Almut Furchert

The Journal of Social Encounters

Though Hildegard of Bingen (1098-1179), Benedictine Abbess and polymath, canonized and proclaimed Doctor of the Church in 2012, has been named a patron of ecology, only fragments of her ecological philosophy exist. This article attempts to introduce Hildegard’s polyphonic work by outlining her theology of viriditas as the green thread that connects her cosmological, anthropological, and ethical theory and to show how it constructs the relationship between humanity and creation as a cosmic partnership. Hildegard's striking visual style is not only inspired by her appreciation of the natural world, but deeply grounded in her theology. This theology entails an ethical …

The Ecofeminist And Gaian Spirituality: Subverting The Patriarchal Discourse In Doris Lessing’S Selected Novels, Shereen Mohamed Safwat

Computer Science

Doris May Lessing (1919-2013) lived most her life on the veld of South Rhodesia (now Zimbabwe) and came back to London in 1949. Her multicultural upbringing allowed her to gain a special connection with nature via her intuitive instinct. This article sheds light on three novels by Lessing namely, The Golden Notebook (1962), The Four-Gated City (1969) and The Memoirs of a Survivor (1974) that are to be tackled within the theoretical frame of ecofeminist and Gaian spirituality. This paper dives into the depth of the Gaian and ecofeminist spiritual realm in the selected novels. It explores the alternative path …

Appalachia In The Anthropocene: An Approach To Understanding Neo Appalachian Narratives As An Affective Ecology, Rachel Michel Bates

English Theses & Dissertations

Appalachia is all too often a commodified and mythologized place in the American consciousness. Yet the lived experience of Appalachia is one complicated by widescale ecological devastation, high poverty rates, and most recently, a devastating opioid crisis. Though much of Appalachian literature continues to dwell in an old vision of Appalachia, an endeavor Zackary Vernon terms post-Appalachian, I argue that a subset of texts published around the turn of the millennium, a time when many of the labor-dependent, exploitative industries such as logging, hydro damming, and coal mining were no longer at work in the region, reveal a shift in …

Eco-Virtue Ethics And Anthropological Commitments Of Laudato Si’ And Laudate Deum: Towards A Renewed Integral Ecology, Ugochukwu Stophynus Anyanwu

The Journal of Social Encounters

The Fourth Chapter of Laudato Si’ (LS) of Pope Francis deals with the theme of ‘Integral Ecology’ from a religious tradition. This chapter can be interpreted as the fulcrum of the encyclical because of the density of its anthropological and ethical considerations. The theme of this chapter has informed a more emphatic presentation in the apostolic exhortation Laudate Deum (LD) on the climatic challenges confronting humanity. Both documents, with incomparable courage and novelty, offer enriching ethical discourses for advancing social, cultural, and human ecology in consonance with social justice, common good, solidarity, and subsidiarity. They contain the magisterial appeal that …

Islam And The Environment, Jon Armajani

The presentation provides (1) some background information about Islam; (2) related ideas about Christianity; (3) a discussion of some verses in the Quran, which relate to the environment, and some Islamic interpretations of them; (4) an analysis of Ibrahim Abdul-Matin’s ideas on Islam and the environment; and (5) a tribute to Father Rene McGraw, OSB.

The Influence Of Abiotic Stress And Cultivar Variation On Plant Defenses And Resistance To Emerald Ash Borer (Agrilus Planipennis) In Cultivated Olive (Olea Spp), Idris B. Elesin

Browse all Theses and Dissertations

Emerald ash borer (EAB), Agrilus planipennis, is an invasive pest that significantly impacts olive trees (Olea europaea). This study aimed to assess the role of abiotic stress factors such as drought and salinity in influencing plant defenses and resistance to EAB, while also examining cultivar variation in resistance. The study specifically aimed to address: (1) What effects do varying degrees of abiotic stress (drought, salinity) have on olive trees' antioxidant and peroxidase activity in olive tree? (2) Do distinct olive cultivars exhibit varying levels of resistance to EAB under various stressors? We used a controlled experimental design with two stress …

Stream Restoration Effectiveness In Mullins Creek In Fayetteville, Arkansas, Amadeo Scott, Shannon Speir

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Lotic waterways are vital for habitat, food, water, and flood protection, but urbanization poses a major threat to their integrity. Runoff from urban surfaces leads to pollution, flashiness, loss of biodiversity, and other symptoms, also known as Urban Stream Syndrome (USS). Streams can be restored in order to combat USS, but most restorations are not monitored, so their long-term effectiveness is unknown. This study quantitatively evaluated a decade-old stream restoration in Fayetteville, Arkansas, to assess its effectiveness in combating USS and achieving set restoration goals, and to gain insights for future restoration projects. Restoration goals included decreasing erosion and sedimentation, …

Probing The Anoxic World Of Coastal Marine Sediments In New England: Understanding The Novel Partnership Between Protists And Their Bacterial Symbionts, Raúl A. Gutiérrez

Open Access Master's Theses

In the oxygen-depleted environments of New England's coastal marine sediment, microbial communities engage in symbiotic interactions to overcome energy deficiencies from oxygen limitation. Among these interactions, ciliates, known for their ability to form diverse symbiotic relationships, play a prominent role. The ciliated protozoa, Metopus sp. commonly form symbiotic relationships with bacteria and archaea that support their fermentative metabolism (Fenchel and Finlay, 1995), though the diversity of these partnerships, particularly in the ocean, is poorly known. To gain insights into the interactions between Metopus ciliate cultures and their microbial partners, we employed Fluorescence in Situ Hybridization (FISH) with species-specific probes. We …

Queering Ecology: Three Investigations From Indigenous Women In Post-Conflict North Sumatra, Perdana Roswaldy

Antropologi Indonesia

Feminists and environmental scholars draw connections between gender inequality, heterosexism, and the devastating impact of environmental catastrophes on the livelihoods of women and gender minorities, exacerbating their precarity. This body of scholarship has begun to imagine alternatives to patriarchal gender and heterosexual norms for reconciling the relationship between humans and nature by calling for "queer(ing) ecology." I investigate the possibility of queering ecology by posing three theoretical concerns in opposition to anthropocentric and gendered preconceptions about nature: its idleness, naturality, and rightfulness. Respectively, I will dissect such presumptions by questioning nature as metaphors, investigating "the natural" attribute in nature, and …

The Deep Ecology Movement

The International Journal of Ecopsychology (IJE)

There are two great streams of environmentalism in the latter half of the twentieth century. One stream is reformist, attempting to control some of the worst of the air and water pollution and inefficient land use practices in industrialized nations and to save a few of the remaining pieces of wildlands as "designated wilderness areas." The other stream supports many of the reformist goals but is revolutionary, seeking a new metaphysics, epistemology, cosmology, and environmental ethics of person/planet. This paper is an intellectual archeology of the second of these streams of environmentalism, which I will call deep ecology.

Eco-Interoception: What Plants, Fungi And Protista Have Taught My Body, Sara Riley Dotterer

Art Theses and Dissertations

To me, ecology is the relational, full-body awareness that I am made up of and deeply connected to everything around me; and for better or worse, this is reciprocal. I form ecotones, an ecological transitional zone between two ecosystems, with the world around me. I use this ecotonal lens to blur binaries and dissolve boundaries between me and the world “outside my body.” During my Masters of Fine Arts at Southern Methodist University, I have continuously explored and represented the lives of various more-than-human species outside of my body, including plants, fungi and protista through an ecotonal lens. Although these …

Connecting Social And Ecological Systems In Small-Scale Fisheries In The Philippines, Sara Eisler Marriott

Dissertations

Nearly 50% of all marine fish capture in the Philippines is from artisanal fisheries, most of which is un- or under-reported. As in many emerging nations around the world, the Philippines cannot fully address overfishing by managing only half of the catch that comes from commercial fisheries. Marine reserves are a popular governance strategy for conservation and of growing interest for fisheries management. Many marine reserves in the Philippines, however, are not considered effective. In 2014, Rare, an international NGO, implemented a community-based management program to increase the effectiveness of the marine reserves, and while it found biomass increased, there …
