The Arctic Ocean Region : Biodiversity, Governance And Protective Measures, Antonios Andreadakis, Graeme Chesters, Dimitrios Dalaklis, 90 North Foundation

Reports

EXECUTIVE SUMMARY

• The Arctic Ocean region stands at the forefront of global environmental transformation, serving as a harbinger of climate change and a frontier for emergent geopolitical and economic interests.

• The Arctic region's economic potential, particularly in shipping and resource extraction, appears to offer shorter trade routes, reduced fuel consumption, and increased access to high-value resources. However, this analysis largely ignores the complex geo-physical, environmental and geographical limitations of the region.

• The fragility of Arctic Ocean ecosystems – characterized by slow ecological recovery, specialised biodiversity, and extreme environmental conditions – renders them especially vulnerable to anthropogenic disturbances. …

Adaptation For Whom? Understanding The Impacts Of Dyke Policies On Small-Scale Farmers In Ca Mau Province Of Vietnam, Nguyen Minh Quang, Nguyen Van Minh, Nguyen Vo Chau Ngan, Martha B. Lerski

Publications and Research

Low-lying deltas worldwide are extremely vulnerable to sea-level rise. As the risks of climate-induced flooding become increasingly clear, the thirst for infrastructure-driven adaptation increases. This highlights a patent need to understand the impacts of engineering adaptation solutions, especially those targeting built structures such as dykes and sluices, on farmers from a bottom-up, farmer-centred perspective. The study addresses this call by examining cases where dyke policies, while successful in some dimensions, have undermined small-scale farmer livelihoods in Ca Mau ― Vietnam’s southernmost rural province. It identifies areas in need of attention and adds empirical data related to this group of farmers. …

Pygoscelis Penguins Prefer Different Oceanographic And Terrestrial Habitats During The Austral Summer, Katherine L. Gallagher, Rachel Herman, Katherine Walton, Michael S. Dinniman, Heather J. Lynch

OES Faculty Publications

Pygoscelis penguins interact with both terrestrial and marine environments, especially during the austral summer when they raise their chicks. Accessible ice-free ground spaces serve as locations for penguins to build colonies and successfully raise chicks while the surrounding marine environment serves as the foraging grounds for adult birds. Penguins must be able to navigate through the waters around their colonies to forage for Antarctic krill (Euphausia superba), their primary prey during the austral summer. Krill, whose distributions are driven partially by the surrounding physics and partially by their behaviors, must also be plentiful in the waters near the …

Huchum: The Legacy Of Fire Suppression, Indigenous Land Management, And Media Representation, Carolyn Coyne

Pomona Senior Theses

In my thesis, I examine how various forms of news media from the 1900s to present day in Ohlone territory have framed a particular hegemonic ideology around fire that matches early colonial journal entries – an ideology that is fueled by fear, sensationalism, and exclusion and directly commits violence against the Ohlone people. I investigate this time period because this is when modern news corporations, like The New York Times, rose into prominence. Specifically, I question how media representations of fire inform regulations over controlled burns; what are the similarities in discourse between media framing and policy? What tactics are …

Fire History, Ecological History, And Historical Human-Environment Interactions In The Northern Great Plains, James Victor Benes

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

This dissertation explores the spatiotemporal signatures of fire in North American grassland ecosystems. In three chapters, I explore different aspects of fire history in the northern Great Plains. Chapter 1 is an introduction. Chapter 2 focuses on the Euro-American Settlement Period (ca. 1850–1950 C.E.). Fire histories from six different lakes in the Nebraska Sandhills are compared with two periods of historic drought and the establishment of United States Post Offices. Five of the six records show increased levels of biomass burning during the initial phases of Euro-American Settlement. Chapter 3 is a long-term (ca. 15,000 years), high-resolution fire history and …

Fire And Mammal Herbivory On Arthropods In The Protected Savannas: A Systematic Review, Ludzula Mukwevho, Mduduzi Ndlovu, Frank Chidawanyika

All Peer-Reviewed Publications

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 …

To wrap-up the lesson, students will pair up, then reflect on their model and then individually write or draw their takeaways.

Effects Of Round-Up On The Environment, Sandra J. Marcu

Journal of Earth and Life Science

Many people around the world have used and still currently use Roundup but are unaware of the effects it has on the environment. Roundup is a spray on application weedkiller that is widely used around the world today both residentially and commercially. It enables its user to grow a garden or a field of crops with a no-tilling approach to eliminate weeds. It is a well-known and popular choice for killing weeds that has been around since the mid 1970’s (Oca, 2017). John Franz, a Monsanto scientist discovered that glyphosate (main ingredient in Roundup) was an herbicide or weedkiller, and …

The Effectiveness Of The Minnesota Buffer Law And Its Impacts On People, Ellen P. Isakson

Journal of Earth and Life Science

In January 2015, the then-governor of Minnesota Mark Dayton announced new legislation that would require 50-foot vegetation buffers along all waterways in Minnesota; this legislation would come to be known as the Minnesota buffer law, exact requirements being “perennial vegetative buffers of up to 50 feet along lakes, rivers, and streams and buffers of 16.5 feet along ditches” (Albert, 2017; MN Board of Water and Soil Resources [MN BWSR] 4 ). A buffer in the context of vegetation and natural resource management is a strip of vegetation around a body of water “designed to intercept stormwater runoff and minimize soil …

Foraging Opportunists: Encouraging Reconnection With The Land, Madelyne Miller, Sylvia Blodorn, Aine Fannon, Ada Scott, Luke Pruitt

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Contextualizing the history of opportunist and native plant species opens options for land management and reconnection to cultural land practices. By recognizing that opportunist species often spread as a result of relocation for practical usage, we determine that reintroducing these uses can lead to an escalation in harvesting these plants. Uses of opportunist plants are diverse and include food sources, artistic practices, and medicine. Foraging also leads to improved human-land-connectedness as well as a deeper connection to ancestral and cultural traditions, which has been found to improve mental health. Focusing on this method of land management will limit the need …

“Fixing” Settler Capitalism: Un/Sustainability In The Former Fort Ord, Clare M. Beer, Sara Salazar Hughes

Urban and Environmental Studies Faculty Works

California's former Fort Ord Army Base is located on the unceded Indigenous territory of the Ohlone Costanoan Esselen Nation. After seven decades as a training ground for foreign wars, the decommissioning of the base triggered an economic, demographic, and cultural crisis for greater Monterey. The solution to this crisis, the Fort Ord Base Reuse Plan, promised sustainable development in the form of local environmental protection, public higher education, and economic growth. We argue that the Fort Ord Base Reuse Plan illustrates a settler sustainability fix, which the state deploys to secure settler capitalist futurity on the Monterey Peninsula at the …

A Unionid Mussel Biodiversity Hotspot Experiencing Unexplained Declines: Evaluating The Influence Of Chemical Stressors Using Caged Juveniles, W. Aaron Wilson, Christine Bergeron, Jennifer Archambault, Jason M. Unrine, Jess Jones, Braven Beaty, Damian Shea, Peter R. Lazaro, Jody L. Callihan, Jennifer J. Rogers

Plant and Soil Sciences Faculty Publications

Unionid mussel populations in a section of the Clinch River in Virginia, USA, has declined substantially, but the causes of the decline remain unknown. To investigate this zone of decline (ZOD), we deployed juvenile freshwater mussels (Villosa iris in 2012 and Lampsilis fasciola in 2013) in both cages and silos at sites within the Clinch River System. We analyzed mussel tissues for trace element and organic contaminant concentrations, shells for trace elements, and environmental media (total water, dissolved water, particulate sediment, and bedload sediment) for both inorganic and organic contaminants. We found a few differences between mussels deployed in cages …

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, …

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Measuring flame, air, and soil temperatures during wildland fires, including wildfires and controlled burns in land management contexts, is crucial for research and applications in fire ecology, safety, and management in a wide array of ecosystems, from grasslands to forests. However, open-source and commercial systems are needed for measuring and logging flame and air temperatures that are user-friendly, economical, modular, and customizable. This paper details the design, development, and validation of the FireLog system. Laboratory validation experiments demonstrated high measurement accuracy, with a minimum coefficient of determination (R2) of 0.98 and the highest observed root mean square error (RMSE) of …

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 …

Linking Disturbance & Macrophyte Colonization–Extinction Dynamics To Invasion Success & Community Assembly: Integrating Population, Community, & Landscape Perspectives, Joshua T. Armstrong

Theses and Dissertations

Aquatic plants, macrophytes, are foundational components of freshwater ecosystems, influencing abiotic conditions, providing habitat structure, and shaping biodiversity and community assembly processes. Their role is particularly critical in dynamic systems where disturbance regimes and colonization processes interact to shape community patterns and species distributions. Despite their ecological importance, macrophytes remain underrepresented in theoretical and applied studies of metacommunity dynamics and invasion ecology, especially in natural systems experiencing frequent environmental fluctuations. Here we aim to elucidate how macrophytes influence and respond to spatial and temporal variation in aquatic ecosystems, with a particular focus on colonization-extinction dynamics, invasion success, and community assembly. …

Establishing A Microfiber Recovery Rate In Human Lung Tissue, Kylie Nicole Babin-Howard

Graduate Research Theses & Dissertations

Microplastics (plastic particles smaller than 5mm) are of increasing concern to environmental and human health as they have persistently been found in all areas of study—becoming a ubiquitous part of the planet. Microplastics have been found in a variety of human tissues (lungs, blood, brain matter, etc.) yet their health effects are poorly understood, with experimental exposure model studies indicating adverse health effects. Microfibers have been found to be more toxic when compared to other microplastic shapes and are also shed from a majority of everyday items, with environmental reports showing that fibers are more than twice as prevalent than …

Gulf and Caribbean Research

Ensuring the sustainability of marine resources that provide food, economic security and other critical ecosystem services is a major challenge globally. Assessing stakeholders’ knowledge and perceptions of the status of fisheries and how they should be managed can yield important insights to facilitate the development of management frameworks that are likely to assist with achieving sustainability. As a socioeconomically and culturally important and critically endangered species, evaluating stakeholder perspectives on the status of the Nassau Grouper fishery is critical to help inform policy. Knowledge and perceptions of stakeholders working in The Bahamas were assessed using voluntary participatory approaches, including a …

Ocean Acidification Mitigation: Potential Expansion Of Sav Restoration Strategy In The Chesapeake Bay, Cree N. Taylor

UROP Posters

Zostera marina is a species of marine macrophyte that has been largely prioritized in past submerged aquatic vegetation (SAV) restoration initiatives within the Chesapeake Bay because of its 1) previous abundance, 2) demonstrated carbon burial abilities, and 3) observed ability for meadows of Z. marina to ameliorate low pH conditions. Due to the temperature variability and poor water quality associated with anthropogenic disturbances in the Chesapeake Bay, Z. Marina beds have experienced several die-off events with limited capacity for regrowth. This systematic review explored the possible benefits of focusing future SAV recovery initiatives on ensuring a diverse variety of SAV …
