More Than Words: Articulating The Multisensory Experiences Of Protected Area Visitors In Southern Nevada, Sara Nicole Temme

Dissertations and Theses

The complex sensory experiences of visitors to U.S. protected areas are not well understood. Previous research investigates visitor activities, motivations, and the ways place attachment cultivates support for conservation activities and other pro-environmental behavior. However, it is unclear how protected area visitor sensory experiences contribute to these behaviors. This study aims to articulate the multisensory experiences of visitors to the Desert National Wildlife Refuge Complex and the Spring Mountains National Recreation Area in southern Nevada, U.S.A. Specifically, it demonstrates the complexity of these experiences as present, intertwined, and embodied in all visit phases: before, during, and after. Utilizing a mixed-method …

Investigating The Effects Of Climate Change On The Phenology Of Achillea Millefolium, Aquilegia Coerulea, And Penstemon Cyanocaulis, Hannah O’Toole, Kailey Hicks, Lisa Long, Jackson Garske, Anna Sher

DU Undergraduate Research Journal Archive

As the effects of climate change are starting to unearth themselves, the impacts can be observed by tracking the patterns of cyclical natural phenomena also known as phenology, and monitoring how they have changed over time. These cycles are at the crux of making ecosystems viable for their local biodiversity, and understanding the ongoing change allows for further understanding of the ecosystem’s change over time. In this study, we look at the ordinal flowering dates of the Achillea millefolium, Aquilegia coerulea, and Penstemon cyanocaulis over the past century. Our data give insight into how warmer temperatures occurring earlier in …

The Chemical Characterization Of Microplastic Polymer Composition From Various Littoral Environments On Cape Cod, Massachusetts, Leah Kosovsky

Chemistry Honors Papers

The increasing abundance of microplastic pollution in marine environments is a rising concern, and it has the potential to negatively affect the health and sustainability of marine organisms and ecosystems. Microplastics can harm organisms through a variety of chemical, biological, and physical mechanisms. The extent to which they are harmful varies greatly and is significantly dependent on the chemical and physical makeup of the plastic polymer. Due to this variability, it is important to characterize microplastic samples in various environments to better understand the risks associated with the debris in certain areas. Through field research, a spatial analysis of the …

Phylogenetic Tests Of Models Of Viral Transmission, Robert M. Zink, Kenedi Holck, Grant L. Morgan

School of Natural Resources: Faculty Publications

The hunt for the immediate non-human host of SARS-CoV-2 has centered on bats of the genus Rhinolophus. We explored the phylogenetic predictions of two models of viral transmission, the SpilloverModel and the CirculationModel and suggest that the Spillover Model can be eliminated. The Circulation Model suggests that viral transmission occurs among susceptible hosts irrespective of their phylogenetic relationships. Susceptibility could be mediated by the ACE2 gene (important for viral docking) and we constructed a phylogeny of this gene for 159 mammal species, finding a phylogenetic pattern consistent with established mammalian relationships. The tree indicates that viral transfer occurs over …

Monitoring Climate Impacts On Annual Forage Production Across U.S. Semi-Arid Grasslands, Markéta PodˇEbradská, Bruce K. Wylie, Deborah J. Bathke, Yared A. Bayissa, Devendra Dahal, Justin D.

The ecosystem performance approach, used in a previously published case study focusing on the Nebraska Sandhills, proved to minimize impacts of non-climatic factors (e.g., overgrazing, fire, pests) on the remotely-sensed signal of seasonal vegetation greenness resulting in a better attribution of its changes to climate variability. The current study validates the applicability of this approach for assessment of seasonal and interannual climate impacts on forage production in the western United States semi-arid grasslands. Using a piecewise regression tree model, we developed the Expected Ecosystem Performance (EEP), a proxy for annual forage production that reflects climatic influences while minimizing impacts of …

Selection Of Landcover Types By Translocated Female Eastern Wild Turkeys In East Texas, Daniel J. Sullivan, Andrew R. Little, Micah L. Poteet, Michael J. Chamberlain

School of Natural Resources: Faculty Publications

Restoration of eastern wild turkeys (Meleagris gallopavo silvestris) is among the greatest conservation achievements in North America. However, restoration efforts in east Texas have had limited success, resulting in a fragmented distribution of turkeys across the landscape. Restoration success is largely dependent on the ability of translocated individuals to quickly select habitat patches on the landscape. Information on habitat selection of translocated wild turkeys is important to identify high quality release locations that should reduce the probability of translocation failure. Our objective was to describe selection of landcover types by translocated female wild turkeys in east Texas. During …

Resilience Of Working Agricultural Landscapes, Shana Sundstrom, Jennifer Hodbod, Craig R. Allen

School of Natural Resources: Faculty Publications

Many alternative agricultural approaches have been developed as a response to the social and ecological costs of modern industrialized agriculture. These include diversified, organic, sustainably intensified, and ecologically intensified farming systems, each of which addresses different aspects of agriculture as a social-ecological system. However, clear theoretical models that account for human-nature coupling and the importance of scale are lacking. Global change, including climate change, land use change, and other human activities influencing social-ecological systems, is exacerbating uncertainty regarding agriculture system dynamics and increasing the need for comprehensive models that include a dynamical integration of socio-ecological-economic influences. Resilience theory and related …

Remnant Prairies And High-Diversity Restorations Work Together To Support Wild Bees Season-Long, Katie Lamke, David A. Wedin, Judy Wu-Smart

School of Natural Resources: Faculty Publications

The presence of diverse bee communities in an ecosystem is vital for maintaining healthy plant communities, promoting habitat resilience, and supporting agriculture. In the US, wild bee declines have led to increased monitoring efforts, but there remain critical data gaps in much of the Midwest. Here, we sought to examine how variation in richness and abundance of flowering forbs influences the richness and abundance of wild bees across “remnant” tallgrass prairies, “high diversity” prairie restorations, and “low diversity” prairie restorations or degraded grasslands in eastern Nebraska. High-diversity plots attracted no bees in the early season due to a lack of …
