Habitat Suitability Index Model Of The Florida Sandhill Crane (Grus Canadensis Pratensis) In West-Central Florida, Courtney E. Buck
USF Tampa Graduate Theses and Dissertations
The Florida Sandhill Crane (Grus canadensis pratensis) is a state threatened endemic subspecies of the Sandhill Crane (Nesbitt & Tacha, 1997). With a population that was estimated at a maximum of 5,000 individuals in 2003 (Nesbitt & Hatchitt, 2008), it is imperative to identify potentially viable habitats, as Florida is rapidly developing. This research develops a Habitat Suitability Index model to determine unsuitable to optimally suitable habitat locations throughout west-central Florida. To do so, six suitability variables based on the crane’s life history were evaluated: Potential nesting area, immediate nesting area, wetland coverage, foraging area, brooding area, and road proximity. …

Rethinking Map Literacy And An Analysis Of Quantitative Map Literacy, Ming Xie
USF Tampa Graduate Theses and Dissertations
Maps are increasingly being used in traditional and virtual media, and civic discourse on political, social, and environmental issues, among others, is more and more becoming influenced by them. The often-used expression of a “picture tells a 1000 words” has never been so apt in our progressively more visual world. Despite this increased role and importance of maps, map literacy, as a field of research, remains rather underdeveloped. This is especially so for thematic maps, the very type of map that is finding increasing currency in discourse. As part of this under-developed nature of map literacy, the quantitative skills used …

A Playful Life Cycle Assessment Of The Environmental Impact Of Children's Toys, Madeline R. Robertson, Christie Klimas
DePaul Discoveries
Toys aid in children’s progression through developmental stages, yet toy production has an environmental impact. This study is the first comparative life cycle assessment of three children’s toys. A life cycle assessment quantifies the impact of an item in comparable impact categories (i.e. global warming potential in kg CO2 equivalents). In this study, we use open LCA to compare toy impact from production to use. The results indicate that the plastic polybutylene carried the highest impact in terms of global warming potential for our predominantly plastic toy. The addition of a battery to the plush dog increased the toy’s eutrophication …

Politics In The San Clemente Dam Removal, Aylan Matthew Lee
Dissertations and Theses
This study examines the role of politics in the removal of the 106-foot tall San Clemente Dam. The removal project and negotiations provide a case study of the contemporary phenomenon of dam removal. My analysis joins a growing body of social science literature on the social, political, and human dimensions of removal. The San Clemente Dam, which impounded the Carmel River near Monterey, California, was removed in 2015, the largest such project completed in California. Drawing on political ecology and science and technology studies, and using a mixed qualitative approach, I assess both the role of politics in shaping the …

Forest Structure, Composition, And Regeneration After High-Severity And Rapidly Repeated Wildfires In The Central Cascade Range, Sebastian Upton Busby
Dissertations and Theses
Within mid-to-high elevation conifer forests in the Cascade Range, wildfire extent, severity, and frequency are expected to rise due to increasingly drier forest fuels under climate change. Considering dominant species composition, existing forests may be poorly adapted to absorb stress and recover following altered wildfire patterns. We tested the hypothesis that increased fire activity may disrupt the recovery of upper-montane and subalpine forest types by quantifying post-fire forest structure and conifer regeneration after spatially large, severe, and rapidly repeated wildfires in the Central Cascade Range. A stratified random sampling design was used to select field plots (n=122) and drivers of …

Hydrologic Trends And Spatial Relationships Of Stream Temperature And Discharge In Urbanizing Watersheds In The Portland Metropolitan Area Of The Pacific Northwest, Emma Lee Brenneman
Dissertations and Theses
This study explores various relationships of streamflow and stream temperature over the Portland Metropolitan area in two urbanizing watersheds. Four stream temperature and discharge metrics were derived from USGS stream gauges in the Tualatin River and Johnson Creek watersheds and were analyzed for monotonic trends. Additionally, this study explored the sensitivity of stream temperature to air temperature and streamflow to assess where locations throughout the watershed may be more sensitive to these changes. Relationships among stream temperature, air temperature, and streamflow were assessed using linear and nonlinear bivariate regression for yearly values and summer months. Additionally, this study seeks to …

Public, Private And Tribal Lands In Humboldt And Trinity Counties, Nate A. Douglass
Humboldt Journal of Social Relations
This map titled “Public, Private and Tribal Lands in Humboldt and Trinity Counties” was a commissioned project by Dr. Yvonne Everett in the Environmental Science and Management Department at Humboldt State University. The purpose of the map was to depict the overlap in land ownership and native, pre-European territories. The most challenging part of the project was finding a way to successfully represent multiple land ownership layers while also distinctly calling out former aboriginal territories, all in one map. For this, bold dotted lines with soft concentric halos seemed to do the trick. These aboriginal territories were manually digitized from …

Hobet Mine Mountaintop Removal, Brian Murphy
Humboldt Journal of Social Relations
The Hobet Coal Mine is located in West Virginia, and was an active mining site for 41 years. At the time, it was one of the largest surface coal mines in the United States. The impacts of this particular mine are especially pronounced because of the sheer scale of alteration to the landscape caused by removing the peaks of mountains to retrieve the coal. The once verdant and biodiverse mountains have been obliterated, and when the coal is removed, the remaining earth is filled into nearby valleys, creating a flat plateau. This terrain has been destroyed, poisoned, and exploited by …

Northern Appalachian Land Cover, Joshua Shindelbower
Humboldt Journal of Social Relations
This map was created using a combination of GIS, photo editing, and graphic design software after an inspiring road trip through the area. It shows the wide diversity of land cover across the region, and a key weak point in the Appalachian Mountains, known as “The Gaps of the Allegheny,” which allowed European immigrants to move toward fertile land deposited by millions of years of erosion. The reader can see that there is very little unused space in the region. Nearly every non-urban inch of land has been occupied for agricultural purposes, down to the thinnest sliver valleys. This map …

Ball Court Map, Adam Wall
Humboldt Journal of Social Relations
This is a composite map of Structure 30 (STR 30), an ancient Mesoamerican ballcourt in Belize, excavated and documented as an archaeological site by Humboldt State University students and alumni. Each demarcated square or rectangle corresponds to a separate excavation map; field notes were consolidated and digitized individually, then pieced together based on alignment and overlaid atop an outline of the entire structure. Satellite imagery of the site was used as a reference to ensure accuracy. By this method, the previously isolated pockets of data, inherent to individual field notes, instead become parts of a greater whole, allowing a fuller …

Humboldt Journal of Social Relations
This map displays the spatial relationships and distribution of residential features throughout a portion of the Maya hinterlands near the site of Dos Hombres in Northwest Belize. Combining high resolution LiDAR data with detailed archaeology field data has allowed for accurate mapping of the features in this Mayan landscape. A unique aspect of this particular site is the presence of a causeway or “sacbe” which was used by the ancient Mayan people to distribute resources and move throughout their environment. The background terrain was created by manipulating the LiDAR data to generate a unique visualization that displays the human modified …

The Southern California Coast, Gilbert Trejo
Humboldt Journal of Social Relations
The purpose of this map was to create a landscape view of my home region of Southern California that adequately displayed the complexity of it’s natural and man-made terrain. One of the challenges I faced was the amount of labeling in the greater Los Angeles (LA) area. I decided to not include any city borders because moving around LA feels more like moving across various neighborhoods and regions than crossing from one city to another. Slanting the text provided more space without making it too difficult to read. The orientation creates a more interesting layout than the usual north-up orientation, …

Salmon Of The Klamath, Melissa Collin
Humboldt Journal of Social Relations
The Klamath is a diverse bioregion widely known for its abundant population of salmon. It extends through the states of Oregon and California, and has a drainage basin of over 15,000 square miles that flows into the Klamath River. The three most prevalent species of salmon in the region (Coho, Steelhead, and Chinook) have all experienced sharp declines in populations since the mid-20th century. This is due to human activity such as commercial fishing, logging, dams, and urban development that has altered the salmon’s historic migration. This map aims to visualize the various waterways and water bodies that flow throughout …
