Leon Yacher: Scholar, Mentor, And Eclectic Geographer, Michael S. Devivo
The Geographical Bulletin
As Kenzer (2001) has noted, “unlike practitioners in other academic fields, when it comes to the intellectual history of our discipline, geographers love to dabble .” However, examining this dabbling has normally been restricted to examining the contributions of faculty in Ph .D .-granting departments . Indeed, our discipline’s history is rich, but written accounts are incomplete, for the voices of geographers serving in undergraduate programs at colleges and universities of little prestige have for the most part been silent . These programs are housed in institutions that are home to the vast majority of academic geographers, many of whom …

How Short-Term Rentals Impact Summit County, Colorado, Spatially And Economically: A Gis Analysis, Hanna Gilhooley
Geography and the Environment: Graduate Student Capstones
Summit County, Colorado, is experiencing a housing crisis influenced by the rise of short-term rentals (STRs). This project investigates how STRs spatially and economically impact the county. STRs are regarded as a reason for the housing crisis as they take away long-term housing from locals and increase housing market prices. Locals are forced to look for housing in neighboring counties such as Clear Creek, Eagle, Grand, Lake, and Park. Geographic Information Systems (GIS) can be used to analyze the spatial and economic impact of STRs in Summit County. Total population, median household income and STR locations are analyzed in ArcGIS …

Key Largo Mangrove Population Monitoring: A Remote Sensing Analysis And Classification Methodology Review, David Lackajs
Geography and the Environment: Graduate Student Capstones
Mangrove forests are some of the world's most bio-diverse habitats, providing essential services to the surrounding coasts. Removal of these habitats has a devastating impact on the ecosystems within them. The Florida Keys are some of the last areas in the United States with extensive mangrove populations. One specific area, John Pennekamp Coral Reef State Park in Key Largo, has been under state protection since 1959. For that reason, mangrove forest habitats there are less fragmented. This study uses remotely sensed imagery to quantify and analyze mangrove populations in this area using two methods: sub-pixel analysis and supervised classification. The …

Who Lives Where: A Comprehensive Population Taxonomy Of Cities, Suburbs, Exurbs, And Rural Areas In The United States, Brian Edward Johnson, Jason Shifferd
The Geographical Bulletin
This paper answers the question: how many Americans live in cities, suburbs, exurbs, and rural areas in the United States? Previous works have examined only one or some of these settlement types instead of accounting for the entire country’s population, or have employed highly technical classifications uncommon in common parlance. T his paper develops a comprehensive classification scheme using vernacular settlement types, then organizes U.S. Census data into the taxonomy presented here. This research contributes to the existing literature by (1) reporting the number and percentages living in all four major settlement types rather than covering only one or two …
