Interpretive Programs For Natural Resource Interpretation At Glacier Point, Yosemite National Park, California, Shannon Brianne Glendenning

Natural Resources Management and Environmental Sciences

This guide to Natural Resource Interpretation in the Glacier Point Region of Yosemite National Park, California was developed over three summers of research and implementation. The range of programs developed to inform the public about the regional and local natural resources are: formal, semi-formal, ranger led hikes and walks, activity based programs, and informal visitor contacts. The programs were designed to inform park visitors about the natural, social, and historical resources in the region. The overall objective is to connect the visitors with the marvels and wonders of the natural resources at Glacier Point in Yosemite National Park, California. This …

A Hidden Markov Model For Earthquake Declustering, Zhengxiao Wu

Research Collection School of Economics

The hidden Markov model (HMM) and related algorithms provide a powerful framework for statistical inference on partially observed stochastic processes. HMMs have been successfully implemented in many disciplines, though not as widely applied as they should be in earthquake modeling. In this article, a simple HMM earthquake occurrence model is proposed. Its performance in declustering is compared with the epidemic-type aftershock sequence model, using a data set of the central and western regions of Japan. The earthquake clusters and the single earthquakes separated using our model show some interesting geophysical differences. In particular, the log-linear Gutenberg-Richter frequency-magnitude law (G-R law) …

Northern Great Plains Network Vital Signs Monitoring Plan, Robert A. Gitzen, Marcia Wilson, United States National Park Service, Northern Great Plains Inventory And Monitoring Network, Mike Bynum, John Wrede, Joshua J. Millspaugh, Kara J. Paintner

United States National Park Service: Publications

Executive Summary

The condition of natural resources in parks and other units of the National Park Service (NPS) is fundamental to this agency’s mission to manage park resources “unimpaired for the enjoyment of future generations.” Park managers are increasingly confronted with complex and challenging resource management issues and need a broad-based understanding of the status and trends of park resources for the long-term protection of park ecosystems. The National Park Service has initiated a long-term ecological “Vital Signs” monitoring program to provide the minimum infrastructure needed to track the overall condition of natural resources in parks and to provide early …

Learning Sustainable Development: Chimeneas De La Esperanza, Miriam V. Mollan Gundersen

Social Sciences

Social inequality and environmental degradation are motivating informed young people into action and connecting impoverished regions of the world with students in more developed nations. This Social Sciences senior project is to analyze an alternative development model designed by a group of Californian university students. The project, named Chimeneas de la Esperanza, is designed to help impoverished Nicaraguan women start a ceramics business. The major hurdle of this mission is to establish a market for the ceramics product. Energy efficient ceramic stoves and smoke ventilating chimneys would benefit the community and avoid an impacted crafts market. The project encompasses ideas …

Climate Change And Human Health Consequences, Jennifer Alford

Social Sciences

The intent of this project is to highlight the human health ramifications of climate change and the strategies for coping with this challenge. Possible effects may include reduction in agricultural outputs, dwindling freshwater aquifers, intensification of tropospheric ozone, and expanding areas of disease-carrying vectors. Because humans are closely connected with their environment, we are directly affected by any environmental disturbance. Consequently, human health is vulnerable to the effects of climate change. The questions are: what are those consequences, how will we adapt, and what does the future hold?

Brazilians In The United States, 1980—2007, Laird W. Bergad

Center for Latin American, Caribbean, and Latino Studies

Introduction: This report examines demographic and socioeconomic factors concerning Brazilians in the United States between 1980 and 2007.

Methods: Data on Latinos and other racial/ethnic groups were obtained from the U.S. Census Bureau American Community Survey, reorganized for public use by the Minnesota Population Center, University of Minnesota, IPUMSusa. Cases in the dataset were weighted and analyzed to produce population estimates.

Results: The wave of migration from Brazil which began in the 1990s in all likelihood will continue into the future, economic fluctuations in the U.S. notwithstanding. In part this is due to the relatively high rates of educational attainment …

Smart Density: A More Accurate Method Of Measuring Rural Residential Density For Health-Related Research, Peter M. Owens, Linda Titus-Ernstoff, Lucinda Gibson, Michael L. Beach, Sandy Beauregard, Madeline A. Dalton

Dartmouth Scholarship

Studies involving the built environment have typically relied on US Census data to measure residential density. However, census geographic units are often unsuited to health-related research, especially in rural areas where development is clustered and discontinuous. We evaluated the accuracy of both standard census methods and alternative GIS-based methods to measure rural density.

Review Of The Separatist Conflict In Sri Lanka: Terrorism, Ethnicity, Political Economy, By Asoka Bandarage, Robert Stoddard

Geography Program: Faculty Publications

Asoka Bandarage, who provides a very thorough discussion of the civil conflict in Sri Lanka, relates the particular issues and perspectives of the contending groups to major conflicts occurring elsewhere in the world. Although the following categories are not utilized specifically by Bandarage, this review considers four general principles that apply both to the Sri Lanka situation and to contemporary conflicts elsewhere. First, when competing groups claim the same land because both have occupied it “traditionally,” how far back in history is meaningful? A second issue concerns how contemporary self-determination is established. That is, what is the appropriate geographic scale …

Revised Relative Abundance Estimates And Temporal Activity Of Bats At Three Great Lakes National Parks Based On Acoustic Data, Bruce W. Miller

United States National Park Service: Publications

Abstract

In this study, Miller re-analyzed acoustic bat data collected from June-August 2003 that was part of a baseline inventory of bat species in three national parks in the Lake Superior region. While the original study presented base-line data on the presence/absence of bat species in these parks, this reanalysis provides estimates of relative abundance and temporal activity of the identified species. Using a suite of recently developed acoustic analysis tools, Miller created species specific filters. This allowed parsing of calls from non-fragmented sequences and differentiate between two species, Myotis septentrionalis and Myotis lucifugus, that were combined into a …

The Changing Contexts And Transboundary Dynamics Of Reconciling Conservation And Development In The Amazon Borderlands, David S. Salisbury, Jorge Vela Alvarado, Cloe R. Franko

Geography and the Environment Poster Presentations

The 12,000 kilometers of international boundaries within the Amazon’s lowland rainforest biome form the axis of a borderland region shared by the nine states of Amazonia (Figure 1). These Amazon borderlands contain high concentrations of conservation units and indigenous territories to preserve the transboundary region’s rich ecological and cultural diversity (Figures 2 & 3). However, this biocultural diversity is increasingly threatened by advancing development frontiers and a growing global demand for Amazonian resources.

Mapping Energy Poverty In Huntington, West Virginia, Elizabeth Anne Callicoat

Theses, Dissertations and Capstones

Energy poverty is a growing phenomenon culminating from the combination of low to mid household income, deteriorating housing structures and rising household energy costs. Energy prices are increasing for all households, but the burden is proportionally larger for those with low to mid income. These groups must sacrifice to afford energy and are often unable or do not have the autonomy to make structural improvements, especially if they rent their home. Data on residential dwellings from the Cabell County Tax Assessor? Office were used within a geographic information system to map where energy poverty likely exists within the city limits …

An Extraordinary Example Of Photokarren In A Sandstone Cave, Cueva Charles Brewer, Chimantá Plateau, Venezuela: Biogeomorphology On A Small Scale, Joyce Lundberg, Donald A. Mcfarlane, Charles Brewer-Carias

WM Keck Science Faculty Papers

A distinctive suite of small-scale erosional forms that are oriented towards the light occur close to the entrance of Cueva Charles Brewer, a large cave in a sandstone tepui, in SE Venezuela. These are the third example of photokarren ever studied in the world, the other two being from Borneo and Ireland. They are the only photokarren ever described from sandstone, and the only example from a non-carbonate environment. The host rock is a poorly-lithified unit of the Precambrian quartz arenite of the Roraima Supergroup. The forms are all oriented towards the light at 30° regardless of rock surface orientation. …

A Unique Population Of Cave Bears (Carnivora: Ursidae) From The Middle Pleistocene Of Kents Cavern, England, Based On Dental Morphometrics, Donald A. Mcfarlane, Martin Sabol, Joyce Lundberg

WM Keck Science Faculty Papers

The ‘breccia’ stratum from Kents (we follow local tradition in using the form ‘Kents’, without an apostrophe) Cavern, England, has been well known for its rich yield of cave-bear material since excavations began in the mid-19th century. Recent work has established that the bears are of latest MIS 12 or earliest MIS 11 age. A life table based on a collection of 67 molariform teeth is consistent with the use of the cave as a hibernaculum. Univariate and morphological assessment of the teeth shows an unusual range of primitive and more derived characters. Multivariate morphometric analysis of cave-bear teeth from …

Polycentrism And Flux In Spatialized Management: Evidence From Maine's Lobster (Homarus Americanus) Fishery, Jennifer F. Brewer

Geography

Spatial approaches to fisheries management hold great promise but require continued conceptual and policy development. Polycentrism and flux emerge as useful concepts, drawing lessons from more customary, informal resourceuse patterns to produce more innovative “spatialized” policies within existing governance architectures. Empirical evidence from Maine shows that pioneering efforts have been limited by the single-species focus of conventional management hierarchies. As entry limits have consolidated the fishing fleet and eliminated flexible, diversified, and adaptive business strategies, cross-species and habitat externalities have become problematic. State lobster (Homarus americanus Milne- Edwards, 1837) comanagement zones have achieved some successes, including trap limits and improved …

Book Review Of Frontiers Of Femininity: A New Historical Geography Of The Nineteenth-Century American West By Karen M. Morin, Christina E. Dando

Geography and Geology Faculty Publications

I found myself drawn again and again to the striking image on the cover of Karen M. Morin’s Frontiers of Femininity, a mirror image created from two photographs, with one reversed. Left, we have a group on Overhanging Rock at Yosemite. Right, we have two women dancing on the Rock, silhouetted against the sky. The experience of being on the edge, of being the edge is central to Morin’s collection of essays in Frontiers of Femininity. The complex frontier that Morin explores calls to mind not only Turner’s frontier but Gloria Anzaldúa's ‘borderlands’:

the Borderlands are physically present wherever …

The Potential For Origin-Based Mobility Management Plans In The Greater Dublin Area, David O'Connor

Conference Papers

Personalised Travel Planning, a form of mobility management planning targeted at the trip-origin (in other words at residential areas), has proved to be a reliable and cost-effective means of reducing car usage in favour of other more sustainable travel forms. These direct-marketing schemes, which target communities with individually tailored travel information materials, succeed in reducing car usage with no investment in hard infrastructure. The concept, when subjected to rigorous academic and other independent scrutiny, has reportedly achieved consistent mode transfers away from car-usage of five to fifteen per cent. This has often taken place in lowdensity areas of high car …

Do Zoos And Aquariums Promote Attitude Change In Visitors? A Critical Evaluation Of The American Zoo And Aquarium Study, Lori Marino, Scott O. Lilienfeld, Randy Malamud, Nathan Nobis, Ron Broglio

Zoos and Aquariums Collection

Modern-day zoos and aquariums market themselves as places of education and conservation. A recent study conducted by the American Zoo and Aquarium Association (AZA) (Falk et al., 2007) is being widely heralded as the first direct evidence that visits to zoos and aquariums produce long-term positive effects on people’s attitudes toward other animals. In this paper, we address whether this conclusion is warranted by analyzing the study’s methodological soundness. We conclude that Falk et al. (2007) contains at least six major threats to methodological validity that undermine the authors’ conclusions. There remains no compelling evidence for the claim that zoos …

Integrated Pest Management (Ipm) For Vertebrates: Do We Need To Broaden This Concept?, John Hadidian

Ecology Collection

The concepts and practices of Integrated Pest Management (IPM) are historically grounded in programs aimed at insects and disease-causing organisms affecting agriculture. When applied to vertebrates, IPM concepts have most often been used in rodent control programs. Still, IPM is a powerful model that arguably can, and should, apply to conflicts with any “pest” or problem-causing organism. It may be time to examine contemporary IPM approaches and their relation to traditional vertebrate pest control more closely. Vertebrate IPM should encompass not only the development of sound and practical steps to shape decision-making and actions, but a dialogue about ethics as …

Scampering In The City: Examining The Ecological And Social Viability Of Black-Tailed Prairie Dogs (Cynomys Ludovicianus) In Denver, Colorado, Lauren K. Morse

Electronic Theses and Dissertations

The conservation of prairie dogs is highly contested due to the embedded view that they are pests. This research addressed the ecological and social viability of prairie dog colonies in Denver, Colorado. Remote sensing analysis was applied to identify potentially viable areas for urban prairie dog colonies. In order to assess the social viability of urban colonies, knowledge and attitudinal surveys were distributed to residents near existing colonies and residents near potential colonies. Statistical analysis of responses provided insight into relationships between proximity to colonies, ecological knowledge, attitudes towards prairie dogs, demographics, and the presence of educational literature. Results indicated …

Emergent Geographies In Green Energy, Sean Tierney

Electronic Theses and Dissertations

A consensus on climate change is spurring an energy transition, but the geography of this transition is uneven and this paper evaluates the energy landscape globally, in the United States and in Colorado. Developed countries have taken the lead in installations and of next generation energy technology ownership. Green electricity has still not achieved parity with fossil fuels, which puts their adoption in the hands of policy makers who are trying to spur innovation with minimal financial disruption. Yet the future of green electricity is in question due to weak and fragmented policy regimes, but also because of inadequate R&D …
