Spatial Ecology Of Mountain Lions Throughout Their Distribution In California, Kyle Duncan Dougherty Jul 2024

Spatial Ecology Of Mountain Lions Throughout Their Distribution In California, Kyle Duncan Dougherty

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

Mountain lions (Puma concolor) have been studied extensively throughout their wide geographic distribution in the Western Hemisphere, but most research has been conducted at relatively small spatial scales. We used GPS telemetry data contributed by researchers in 16 study areas throughout California to advance understanding of mountain lion spatial ecology. First, we investigated multi-scale resource selection of mountain lions relative to spatially varying risk of intentional human-caused mortality associated with livestock depredation management. We show that individuals that proactively avoided mortality risk when selecting home ranges were able to relax their avoidance of risk when making resource selection …

Impact Of Rainfall On Air Temperature, Humidity And Thermal Comfort In Tropical Urban Parks, Juan A. Acero, Philip Carl Kestel, Hieu T. Dang, Leslie K. Norford Jul 2024

Impact Of Rainfall On Air Temperature, Humidity And Thermal Comfort In Tropical Urban Parks, Juan A. Acero, Philip Carl Kestel, Hieu T. Dang, Leslie K. Norford

Research Collection College of Integrative Studies

Urban areas in hot and humid tropical regions are frequently exposed to uncomfortable thermal levels. A well-developed urban heat mitigation strategy is increasing vegetation infrastructure, even though the impact differs based on regional climate. In this study we have evaluated the impact of rainfall on air temperature, humidity and thermal comfort inside a large urban park in Singapore, based on measurement campaigns. A comparison between the park and an urban site is presented. Results show that rainfall significantly reduces air temperature and improves thermal comfort levels, not only right after the rain event but also in the after-event dry period. …


Evaluating Urban Fire Vulnerability And Accessibility To Fire Stations And Hospitals In Austin, Texas, Akhil Mandalapu, Kijin Seong, Junfeng Jiao Jul 2024

Evaluating Urban Fire Vulnerability And Accessibility To Fire Stations And Hospitals In Austin, Texas, Akhil Mandalapu, Kijin Seong, Junfeng Jiao

Research Collection College of Integrative Studies

Anthropogenic climate change has increased the frequency and intensity of fires. Despite their widespread consequences, current research has largely overlooked urban fires and their associated vulnerability. This study seeks to identify patterns of fire vulnerability, map out areas with high fire vulnerability and limited access to fire stations and hospitals, and ultimately determine the factors contributing to increased fire incidents. Principal Component Analysis was used to develop a fire vulnerability index comprising variables capturing health status and socio-environmental factors. Enhanced 2-step floating catchment area (E2SFCA) analysis was conducted to determine relative accessibility to resources such as hospitals and fire stations. …


Bridging The Nature-Cultural Heritage Gap: Evaluating Sustainable Entanglements Through Cemeteries In Urban Asia, David Ocon, Wei Ping Young Jul 2024

Bridging The Nature-Cultural Heritage Gap: Evaluating Sustainable Entanglements Through Cemeteries In Urban Asia, David Ocon, Wei Ping Young

Research Collection School of Social Sciences

The expanding footprint of urban Asian settlements and increasing living standards have put pressure on cemetery sites. Public health narratives and the sanctity associated with death matters in Asian urban landscapes have fed into the rhetoric of cemeteries as undesirable heritage spaces. Often lacking protection, many cemeteries have been exhumed, cleared, and relocated to allow room for new developments and infrastructure, risking the survival of this quiet element of the urban cultural patrimony. Within an Asian context, synergies between nature and cultural heritage preservation are not prevalent in major cities like Singapore, Hong Kong, Tokyo, Manila, Kuala Lumpur, and Bangkok. …

Luck In The Life Of A Geographer, Yi-Fu Tuan Jun 2024

Luck In The Life Of A Geographer, Yi-Fu Tuan

The Geographical Bulletin

Luck plays a far greater role in our life than we are willing to acknowledge, for the obvious reason that it detracts from our role as agents. I, for one, used to see myself as planning my career path and then following it. Only now, in extreme old age, do I find the idea of that planned life untenable. Looking back, at critical points, it was not the wisdom of my planning, but rather happenstance that took me to the more fruitful way. Let me start with graduate school, a choice I had to make in my last year as …

The Deviant Geographer, Janice Monk, Casey D. Allen Jun 2024

The Deviant Geographer, Janice Monk, Casey D. Allen

The Geographical Bulletin

I’ve spent my life being a deviant. When I say that, I don’t necessarily mean in a delinquent sense (though that has been necessary at times). Rather, I mean I’ve always had to approach things differently. Things about your own life and background can help to shape and widen the ways in which we study, and how we see the world – even if you don’t realize it. For me, it was a combination of breaking my work-a-day upbringing cycle (I came from a working-class family and lived/grew-up in the Petersham suburb, west of downtown Sydney, Australia) and being the …


Deep In The Karst: Foundations For A Career In Geography, Michael F. Goodchild Jun 2024

Deep In The Karst: Foundations For A Career In Geography, Michael F. Goodchild

The Geographical Bulletin

In the last lines of his poem “In Praise of Limestone”, W.H. Auden wrote, “[W]hen I try to imagine a faultless love or the life to come, what I hear is the murmur of underground streams, what I see is a limestone landscape”. When I was 12, my family moved to two acres of land underlain by Devonian limestone in Paignton, county of Devon, southwest England. At age 15, I began exploring the local caves – small, tight, but beautifully decorated. Later, studying physics at Cambridge, I found the University’s caving club and spent many happy weekends in and under …


Revisiting Geomorphological Hotspots, Andrew Goudie Jun 2024

Revisiting Geomorphological Hotspots, Andrew Goudie

The Geographical Bulletin

In 1996, just a quarter of a century ago, I wrote a paper called “Geomorphological ‘hotspots’ and global warming” (Goudie 1996). My motivation to choose this theme, was that various biogeographers and ecologists, fearing loss of biodiversity due to human activities, had used the phrase “biodiversity hotspots” for those areas that may be of greatest significance because of their sensitivity and the richness (and endemicity) of their fauna and flora. A leader in this was a forester, Norman Myers, who had published an influential paper in 1992. T his made me wonder whether there were “geomorphological hotspots” where the environment …


Viral Worlds: Zika And Matter Of Global Health Futures, Deborah Dixon Jun 2024

Viral Worlds: Zika And Matter Of Global Health Futures, Deborah Dixon

The Geographical Bulletin

As a site for ‘cutting edge’ research, virology has a profoundly conservative genealogy, its promulgations on the origins of viral disease intimately wrapped in prognostications on the ending of human life. Since the late 19th century, a concern for the reach of pathogenic viral matter into human bodies has emerged as a deeply colonial project, with fears over the transformation of endemic diseases into epidemic ones conjoined with cautions of population decline in the colonies and disrupted trade routes. Colonial authorities in Africa, Asia, the Caribbean and Latin America framed viral disease as a ‘public health’ problem – a problem …


Find Your Special Place, David R. Butler Jun 2024

Find Your Special Place, David R. Butler

The Geographical Bulletin

Geographers come in all varieties, but many of the best geographers study – and have found – their “special place”. I present examples of work over the course of my career in my special place, Glacier National Park, Montana. Finding your own special place will serve you well and hopefully carry you through the tough times that inevitably occur during (student) life. Geographers study places all over the world and beyond, as well as places in the imagination. We use a diversity of tools and methods in the process. Indeed, some geographers are known primarily as “methods” geographers associated with …


Geography, Exploration, And Metaphor, Carol Harden Jun 2024

Geography, Exploration, And Metaphor, Carol Harden

The Geographical Bulletin

Geography, as the study of the world and its many interrelated components, presents an enormous range of opportunities for exploration and discovery. Some explorations involve travel and physical activity while others occur in offices, archives, or focus groups. As a discipline that encompasses a large range of research topics and methods, geography attracts a diverse community, including individuals with multiple interests. Although developing and maintaining focus is necessary for increasing expertise and authority, having a broader view gives us more perspectives to draw from and, often, facilitates new insights into causal relationships among seemingly disparate elements of our worlds. The …


Lithological And Geotechnical Characterization Of Casablanca’S Urban Subsoil, Morocco, Imane Fahi, Fouad El Kamel, Toufik Remmal, Halima Jounaid, Fouad Amraoui, Houssine Ejjaouani Jun 2024

Lithological And Geotechnical Characterization Of Casablanca’S Urban Subsoil, Morocco, Imane Fahi, Fouad El Kamel, Toufik Remmal, Halima Jounaid, Fouad Amraoui, Houssine Ejjaouani

The Geographical Bulletin

Morocco’s largest city, Casablanca, is expanding rapidly, but geotechnical characteristics related to the region’s subsoil are rarely taken into consideration during construction/building projects. Using field studies, along with a significant database established from civil-engineering work, this study focuses on the lithological and mechanical characterization/behavior of Casablanca’s subsoil in order to gain a clearer interpretation of Casablanca’s (sub)soil. Lithology maps and cross-sections show the variation of Quaternary cover thickness, which is controlled by the shape of the synclines and anticlines in the folded Paleozoic bedrock. The texture of surface soils was described by percentage of gravel, sand, silt, tuff, and clay, …


The Journey, Dawn J. Wright Jun 2024

The Journey, Dawn J. Wright

The Geographical Bulletin

While I’m an oceanographer first and foremost, I do have formal training in (physical) geography and terrestrial geology. And this background has allowed me to achieve some pretty neat things, especially so considering I’m a Black American female scientist. I’m pretty modest when it comes to tooting my own horn, but when hard work pays off, being acknowledged can be refreshing. I’ve been to bottom of the ocean. I’ve mapped the ocean floor. Well, a lot of it – but in 3D – and we’ll hopefully have the entire seafloor mapped by 2030. But accomplishments aside, I’d like to give …


Modeling The Risk And Potential Spread Of The Asian Long-Horned Beetle In Southeast Michigan, Stephanie Carr, Rudy Bartels, Lisa Dechano-Cook, Diana Casey Jun 2024

Modeling The Risk And Potential Spread Of The Asian Long-Horned Beetle In Southeast Michigan, Stephanie Carr, Rudy Bartels, Lisa Dechano-Cook, Diana Casey

The Geographical Bulletin

The Asian long-horned beetle (Anoplophora glabripennis) infestation has been an ongoing problem for the Midwest, Northeast, and parts of the South contiguous United States. The purpose of this project is to identify the currently infested areas and to create a potential spread map for counties in Michigan nearest to the Ohio infestation. There is a strong probability that infestations will spread into Michigan. The climate is ideal for the beetle and Michigan’s native tree species, the sugar maple, is its preferred host. Michigan’s most susceptible counties are Monroe, Washtenaw, and Wayne. The potential destruction of Michigan’s maple trees could significantly …

All The World’S A Stage: Aesthetics, Competing Stories And Slum Clearance In Delhi, India, Richard Wolfel Jun 2024

All The World’S A Stage: Aesthetics, Competing Stories And Slum Clearance In Delhi, India, Richard Wolfel

The Geographical Bulletin

The rise of the modern commercial political-economic system is influencing rural to urban migration in addition to urban morphology. Slum settlements are one of the major results of rapid and often unregulated rural to urban migration. Slum settlements create a major problem for developing cities. The slum settlements do not fit the leadership’s vision for a modern city, one that can be marketed to outside businesses and organizations for investment. As a result they are often seen as a nuisance by the leadership and targeted for destruction, especially when the land of the slum is valuable. The process of slum …


Student Cyclists Experience Pm2.5 Pollution Hotspots Around An Urban University Campus, Brett W. Luce, Tate E. Barrett, Alexandra G. Ponette-González Jun 2024

Student Cyclists Experience Pm2.5 Pollution Hotspots Around An Urban University Campus, Brett W. Luce, Tate E. Barrett, Alexandra G. Ponette-González

The Geographical Bulletin

Although cycling has environmental and health benefits, urban cyclists are at risk of exposure to harmful concentrations of fine particulate matter (PM2.5). We used a low-cost particle sensor and MapMyRide to collect geolocated 1-minute PM2.5 measurements along four routes surrounding an urban university campus. Measurements were collected from 7:30-9:30 AM during fall 2017 and spring 2018. We found no significant differences in ride-averaged PM2.5 concentrations among routes, but all routes experienced higher concentrations when winds blew from the southeast-south-southwest. Hotspots, areas with consistently elevated PM2.5 concentrations compared to surrounding areas, were detected along all routes in areas with high traffic …


Thinking Beyond The Plastic Bag Ban: Reusable Bag Habits And Motivators In Athens, Ohio, Jessica Dalzell, Amy J. Lynch Jun 2024

Thinking Beyond The Plastic Bag Ban: Reusable Bag Habits And Motivators In Athens, Ohio, Jessica Dalzell, Amy J. Lynch

The Geographical Bulletin

Despite a growing awareness of the environmental impacts of plastic bags, more states have prohibited disposable bag restrictions than have passed them. In such communities, voluntary actions that shift bag habits from disposable to reusable remain promising. Yet research on reusable bags, and the social geographies of waste reduction, more broadly, lags behind that of other aspects of waste management. This study addresses that gap by examining the reusable bag habits and motivations of residents of Athens, Ohio. It accomplishes this through a survey of Athens residents, complemented by observations at local grocery retailers. Results suggest that most residents own …


The Geography Of Coins: Culture, Politics, And Power Depicted On Money, Cory Frewing Jun 2024

The Geography Of Coins: Culture, Politics, And Power Depicted On Money, Cory Frewing

The Geographical Bulletin

Coins have a language of their own, and governments speak it fluently. This paper discusses the role that coins play in State iconography. As such, coinage can be utilized for pursuing nationalistic ambitions and other centripetal forces that strengthen a State. Likewise, coins can also act as preservers and conveyers of national culture. Religion, language, values, and history have all been prominent subjects on coins from around the world since the Classical Era. Aside from imagery, coins are also products of spatial association, owing their current preponderance to many forms of cultural diffusion. This paper first describes contemporary, circulating world …

Choosing Your Perspective: Finding Adventure In The Middle Of A Crisis, Casey D. Allen, Kaelin M. Groom Jun 2024

Choosing Your Perspective: Finding Adventure In The Middle Of A Crisis, Casey D. Allen, Kaelin M. Groom

The Geographical Bulletin

We arrived in Jordan late August 2019 for Kaelin’s, postdoctoral Fulbright research fellowship: an historical repeat assessment of Petra over the last century. This was not our f irst experience living abroad, having been stationed in Amman (Jordan) a few years previous for my own Fulbright, and subsequently being based in Barbados. In fact, after our first time living in Jordan, we ended up returning on multiple occasions to collaborate with an interdisciplinary team conducting research in Wadi Rum. Jordan is an amazing country with the most hospitable and genuine people we have ever encountered in our somewhat extensive travels, …
