Berry Important? Wolf Provisions Pups With Berries In Northern Minnesota, Austin T. Homkes, Thomas D. Gable, Steve K. Windles, Joseph K. Bump

United States National Park Service: Publications

Wolves (Canis lupus) primarily provision pups by catching mammalian prey and bringing remains of the carcass to the pups at a den or rendezvous site via their mouths or stomach. In August 2017, we observed an adult wolf regurgitating wild blueberries (Vaccinium spp.) to pups at a rendezvous site in the Greater Voyageurs Ecosystem, Minnesota, USA, which is the only known observation of wolves provisioning pups with wild berries. This observation, in combination with other evidence from the Greater Voyageurs Ecosystem, suggests wild berries might be a more valuable food source for wolves in southern boreal ecosystems than previously appreciated.

Modelling Pinniped Abundance And Distribution By Combining Counts At T Terrestrial Sites And In-Water Sightings, Steven L. Whitlock, Jamie N. Womble, James T. Peterson

United States National Park Service: Publications

Pinnipeds are commonly monitored using aerial photographic surveys at land- or ice-based sites, where animals come ashore for resting, pupping, molting, and to avoid predators. Although these counts form the basis for monitoring population change over time, they do not provide information regarding where animals occur in the water, which is often of management and conservation interest. In this study, we developed a hierarchical model that links counts of pinnipeds at terrestrial sites to sightings-at-sea and estimates abundance, spatial distribution, and the proportion of time spent on land (attendance probability). The structure of the model also allows for the inclusion …

Dental Microwear As A Behavioral Proxy For Distinguishing Between Canids At The Upper Paleolithic (Gravettian) Site Of Predmostí, Czech Republic, Kari A. Prassack, Josephine Dubois, Martina Laznickova-Galetova, Mietje Germonpre, Peter S. Ungar

United States National Park Service: Publications

Morphological and genetic evidence put dog domestication during the Paleolithic, sometime between 40,000 and 15,000 years ago, with identification of the earliest dogs debated. We predict that these earliest dogs (referred to herein as protodogs), while potentially difficult to distinguish morphologically from wolves, experienced behavioral shifts, including changes in diet. Specifically, protodogs may have consumed more bone and other less desirable scraps within human settlement areas. Here we apply Dental Microwear Texture Analysis (DMTA) to canids from the Gravettian site of P�redmostí (approx. 28,500 BP), which were previously assigned to the Paleolithic dog or Pleistocene wolf morphotypes. We test whether …

Measuring Spatial And Temporal Shifts In Forest Structure And Composition In T High Elevation Beech Forests In Response To Beech Bark Disease In Great Smoky Mountains National Park, Lee Rubmle, Glenn Taylor, Joshua B. Grinath, Ashley B. Morris

United States National Park Service: Publications

Exotic forest pests and pathogens are among the most serious environmental threats to millions of hectares of forested land worldwide. Beech Bark Disease (BBD) is a non-native, pathogenic complex consisting of associations between scale insects and fungi. First confirmed in Great Smoky Mountains National Park (GRSM) in 1986, this complex has since threatened local high elevation beech forests, which are G-1 ranked (critically imperiled) forest communities where American beech (Fagus grandifolia Ehrh.) is a foundational tree species. In 1994, GRSM initiated the BBD Monitoring Protocol at 10 high elevation beech forest plots in the Park. The plots were sampled biennially …

Prey Of Reintroduced Fishers And Their Habitat Relationships In The Cascades T Range, Washington, Mitchell A. Parsons, Jeffrey C. Lewis, Jonathan N. Pauli, Tara Chestnut, Jason I. Ransom, David O. Werntz, Laura R. Prugh

United States National Park Service: Publications

Conservation and recovery of forest carnivores requires an understanding of their habitat requirements, as well as requirements of their prey. In much of the western United States, trapping and habitat loss led to extirpations of fishers (Pekania pennanti) by the mid-20th century, and reintroductions are ongoing to restore fishers to portions of their former range. Fisher recovery in Washington State has been limited by isolation from other populations, but other potentially important factors, such as diet of fishers in this region and prey availability, have not been thoroughly investigated. We collected hair samples from potential prey and fishers for stable …

Plains Zebra (Equus Quagga) Behaviour In A Restored Population Reveals Seasonal Resource Limitations, Charli De Vos, Alison J. Leslie, Jason I. Ransom

United States National Park Service: Publications

A once abundant species, plains zebra (Equus quagga), is declining across much of sub-Saharan Africa. Reintroduction efforts at Majete Wildlife Reserve, Malawi, have resulted in rapid population increases, but little is known about how such populations resemble natural populations socially or behaviourally, and what those attributes may reveal about restoration success. Incorporating behavioural knowledge into conservation efforts is an important tool for managing the effects of habitat fragmentation and resource competition. The aim of this study was to quantify the daylight time budget of both family and bachelor bands of reintroduced plains zebra to determine if such behaviours …

Predicting Livestock Depredation Risk By African Lions (Panthera Leo) In A Multi-Use Area Of Northern Tanzania, K. Beattie, E. R. Olson, B. Kissui, A. Kirschbaum, C. Kiffner

United States National Park Service: Publications

Human-wildlife conflicts, especially those involving large carnivores, are of global conservation and livelihood concern and require effective and locally-adapted prevention measures. Risk of lion attack on livestock (i.e. depredation) may vary seasonally and may be associated with variation in wild prey abundance or landscape characteristics. To test these competing hypotheses, we used a resource selection approach, and determined whether prey catchability (indicated by geo-spatial variables), or prey availability (indicated by modeled abundance recorded via camera traps) explained spatial and seasonal variation in livestock depredation risk by African lions on Manyara Ranch Conservancy, a multi-use area in northern Tanzania. Seasonal variation …

Remediation Strategies To Reduce Heavy Metal Uptake In Lettuce Grown In Contaminated Urban Soil, Ryley Thomas

Department of Environmental Studies: Undergraduate Student Theses

Urban soils are increasingly used to produce food for local consumption, which requires at the same time management strategies that prevent the plant uptake of potentially present contaminants. This study was conducted to test different soil amendments for their ability to retain lead (Pb) and arsenic (As) within the soil matrix. The analyzed soil was taken from a potential community garden lot near a railroad in Lincoln, NE where elevated concentrations in Pb and As had been detected. Ponderosa pine biochar and spent coffee grounds were used as soil additives because of their documented chemical reactivity towards soil cations or …

Abatement Of Per- And Polyfluoroalkyl Substances With Electrochemical Oxidation, Elise Webb

Department of Environmental Studies: Undergraduate Student Theses

Throughout the United States, there is a growing concern for contamination of groundwater with harmful per- and polyfluoroalkyl substances (PFAS). These forever chemicals have no natural degradation pathways and the science community has not had any significant breakthroughs to remediate contaminated sites. Electrochemical oxidation using a boron-doped diamond (BDD) electrode shows excellent potential for becoming an effective therapy for such PFAS contaminated sites. The objective of this research is to provide proof-of-concept that electrochemical oxidation can degrade PFAS, ensure analysis is accurate, and controls of experimental design are optimal. Electrochemical oxidation degraded 10 mg/L perfluorooctanoic acid (PFOA) under a series …

Effect Of Urban Green Space On Urban Populations., Jack Mensinger

Department of Environmental Studies: Undergraduate Student Theses

As the world's population continues to urbanize, population density increases and people endure the ever-increasing speed of the urban environment. The need to focus on mental and physical health becomes ever more critical as daily routines may not fulfill urban residents' basic needs. The bulk of work studying the relationship between green space, mental, and physical wellness, have had a narrow scope in their assessment of the benefits of green space. Previous studies focused either on the human interaction or the spaces utilities as a corridor and a habitat for flora and fauna. We utilized a systematic literature review to …

Diatom Morphology In Light Of A Changing Climate: A Focus On Aulacoseira Crenulate, Brighid Welchans

Department of Environmental Studies: Undergraduate Student Theses

Fossilized diatoms are arguably the most vital proxy record utilized in paleolimnology. Diatoms are unicellular microalgae that are the basis of countless food webs, are invaluable bioindicators, and generate nearly a quarter of global net primary productivity. Diatoms are affected by a variety of environmental factors but there is relatively little research on how environmental conditions impact diatom valve morphology, and in particular whether there is a correlation between incoming light and diatom pore morphology. This report focuses on the Amazon lowland lake Garzacocha, and analyzes the relationship between light levels and the corresponding size of Aulacoseira crenulata pores. We …

Risk Communication Approaches For Preventing Private Groundwater Contamination In The Republic Of Ireland: A Mixed-Methods Study Of Multidisciplinary Expert Opinion, S. Mooney, J. O'Dwyer, Paul Hynds

Articles

The mechanisms of private-well groundwater contamination are uniquely complex, necessitating a multisector communicative approach to risk management, premised on behaviour promotion. In countries such as the Republic of Ireland (ROI), characterised by oftentimes high groundwater contamination risk and concurrently limited user awareness, incorporation of multidisciplinary, ‘expert-based’ knowledge may facilitate design of evidence-based, practical interventions. Expert interviews represent an efficient form of expert consultation, enabling ease of access to niche information and comparison of procedure, but remain under-utilised within the groundwater management literature. In response, the current study elicited opinion from 50 experts across four broad categories (communications, engineering/science, policy, and …

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 …
