Climate Change And Grief: An Overview Of The Mental Health Effects Of Climate Change And How Biodiversity Loss In The Great Plains Affects Our Emotional Wellbeing, Luke Andersen

Department of Environmental Studies: Undergraduate Student Theses

While it is known that our changing climate is predicted to have dire consequences, there is less discussion taking place about the potential mental health effects and outcomes of those consequences. Many articles outline the mental health consequences of climate change, but they all discuss similar ideas and theories that don't necessarily generate further topics to explore. A topic that remains unexplored is that of ecological grief, which is our emotional response to ecological loss. The hypothesis being tested in this research project is that people will feel relatively strong grief-related emotions (i.e. anger, sadness) when imagining the loss of …

Observing Spectral Response Differences In Freshwater Lakes Using Remote Sensing Technology, Brady Cooper

Department of Environmental Studies: Undergraduate Student Theses

Nutrient pollution is a growing issue around the world. The excess nutrients going into aquatic ecosystems allows phytoplankton to thrive and form algal blooms. Algal blooms can be hazardous to humans, wildlife, and destroy aquatic ecosystems. They also are costly to monitor and control. This study uses remote sensing to observe the spectral differences in lakes, specifically one that experienced an algal bloom, Lake St. Clair. It was also compared to a lake with exceptional water quality, Lake Tahoe. The objective was to see how the two differed spectrally and determine if remote sensing is a viable option for monitoring …

In the Arctic, species within its’ ecosystem are experiencing more dramatic impacts from climatic warming because of the …

A Comparative Analysis Of The Reception Of Laudato Si’ By Progressive And Traditional Catholics, Mikayla Dorff

Department of Environmental Studies: Undergraduate Student Theses

This study considers the impacts of religion, specifically Catholicism, on environmental views. In 2015, Pope Francis published an encyclical entitled Laudato Si’: On Care for Our Common Home. In this encyclical, Pope Francis calls all humans to an “ecological conversion” and identifies environmental stewardship as a Catholic responsibility. Progressive Catholics embraced Laudato Si’ and its messages, while traditional Catholics condemned the encyclical. In this study, a comparative literary analysis is conducted to determine why traditional Catholics reject the encyclical while progressive Catholics applaud it. Initiatives stemming as a direct result from Laudato Si’ are also examined. The study found …

A thematic literature review was conducted in order to find all of the data. Once all of the data was compiled, it …

The Effects Of Phosphate On The Metamorphosis Of Larval Western Barred Tiger Salamanders (Ambystoma Mavortium), Alexis Jean Polivanov

Department of Environmental Studies: Undergraduate Student Theses

This investigation will collect data to assist in determining if elevated aquatic phosphate levels affects the metamorphosis rate of larval western barred tiger salamanders (Ambystoma mavortium). Monoammonium phosphate fertilizers are being used on crops in Nebraska (NDA, 2017). This area lines up with the area the western barred tiger salamanders are disappearing from (Damme, 2018). Monoammonium phosphate is made up of nitrogen and phosphate. There have been several studies showing how nitrogen is harmful to amphibians such as this salamander (Griffis-Kyle, 2007) (Griffis-Kyle & Richtie, 2007), but there have not been many showing how phosphate affects amphibian’s metamorphosis …

Diet Composition And Analysis Of Fish Species Consumed By The Eurasian Otter In A Marine/Costal Environment, Alexandrea Otto

Department of Environmental Studies: Undergraduate Student Theses

Understanding prey preference in Eurasian otters, Lutra lutra, is important to provide greater insight into aquatic predator-prey relationships which will inform conservation efforts. Identifying the composition of an organism’s diet is one of the primary steps in understanding an organism and developing effective conservation strategies. This study expands upon basic identification of consumed items to estimate size of fish eaten by Eurasian otters to provide information on the diet of these important aquatic predators. Many studies on the Eurasian otter have considered diet from river systems, yet less is known of their diet in marine systems. The goal of my …

Gulf Coast Marine Laboratories Past, Present And Future, Donald F. Boesch

Gulf and Caribbean Research

I spent my nearly 50—year career in marine science working at marine laboratories, most of that as a chief executive officer. So, it is appropriate that my reflections are about marine laboratories, rather than my own science. After relating my career course, I turn my attention to the history and development of marine laboratories along the U.S. coast of the Gulf of Mexico (GOM). Surprisingly, the region’s first laboratory was actually constructed in 1903 at Cameron, LA, but operated less than a decade before closing. It was not until after World War II that the university—affiliated marine laboratories of today …

The Effect Of Wildlife Wellbeing On Environmental Concern, Laura Casne
