The Habitat Of European Brown Bears In Northern Spain: Mapping Habitat Fragmentation And Potential Connectivity, Alma D. Pacheco

Graduate Student Theses, Dissertations, & Professional Papers

The European brown bear in northern Spain is considered to be an endangered species whose habitat has been fragmented into two subpopulations due to habitat loss and lack of connectivity. The importance of improving connectivity and preventing more habitat destruction is vital to recover the species in this region. This research looks at spatial and temporal variations of brown bear habitat by mapping the conditions of habitat fragmentation and potential connectivity at a regional extent. This research examines net changes of brown bear habitat fragmentation between 1990-2000, 2000-2006, and overall 1990-2006; and the degree of brown bear habitat connectivity between …

Scale As A Key Factor For Sustainable Water Management In Northwest Honduras, E. Christian Wells, Karla L. Davis-Salazar, Jose E. Moreno-Cortes

Journal of Ecological Anthropology

In northwest Honduras, community-based interventions by outside development agencies seeking to assist communities with the treatment and delivery of potable water have been largely ineffective. This article examines the social, economic, ecological, and engineered contexts of gravity-fed water systems in the Palmarejo Valley of this region, identifying key barriers to long-term sustainability. Drawing from the results of our mixed-methods research in the valley incorporating ethnographic and spatial analyses along with water quality testing, we outline the limitations of community-based development approaches that ignore the broader social and political scales of resource inequalities. We find that water provisioning often requires coordination …

Land Surface Anomalies Preceding The 2010 Russian Heat Wave And A Link To The North Atlantic Oscillation, C. K. Wright, K. M. De Beurs, G. M. Henebry

Natural Resource Management Faculty Publications

The Eurasian wheat belt (EWB) spans a region across Eastern Ukraine, Southern Russia, and Northern Kazakhstan; accounting for nearly 15% of global wheat production. We assessed land surface conditions across the EWB during the early growing season (April–May–June; AMJ) leading up to the 2010 Russian heat wave, and over a longer-term period from 2000 to 2010. A substantial reduction in early season values of the normalized difference vegetation index occurred prior to the Russian heat wave, continuing a decadal decline in early season primary production in the region. In 2010, an anomalously cold winter followed by an abrupt shift to …

Avian Diversity Across Three Distinct Agricultural Landscapes In Guadalupe, Chiriquí Highlands, Panama, Jarred Jones

Independent Study Project (ISP) Collection

Deforestation of tropical forest for agricultural purposes threatens habitat loss of native species. The value of various agricultural landscapes in conserving avian populations is useful in determining diversity-conscious development plans. However, generalized results from regionalscale studies cannot be implemented to insular avian habitats. This study serves as the only current avian diversity study of the Chiriquí Highlands. To determine the effect of agricultural land use within an insular avian habitat, I compared avian diversity and site population similarity in Guadalupe, Chiriquí Highlands of the Talamanca Range, Panama. I hypothesized that avian diversity is greatest at forest edge followed by forest …

Index-Based Insurance And Risk Management Among Nomadic Mongolian Herders , Kelsey Larson

Independent Study Project (ISP) Collection

Mongolian herders must contend with the risk of dzuds, harsh winters that can kill large numbers of livestock. To do so, they use a mixture of formal financial tools and traditional risk mitigation techniques. This paper is a study of the interaction between the Mongolian Index-based Livestock Insurance Program and traditional informal risk mitigation techniques. The researcher interviews herders in Bulgan soum, Arhangai aimag and Galuut soum, Bayanhongor aimag to compare the IBLI program’s impact in a community that has had IBLI since 2006 and one that only received IBLI in 2012. This study finds that insurance purchase is positively …

A Cross Comparison Of Spatiotemporally Enhanced Springtime Phenological Measurements From Satellites And Ground In A Northern U.S. Mixed Forest, Liang Liang, Mark D. Schwartz, Zhuosen Wang, Feng Gao, Crystal B. Schaaf, Bin Tan, Jeffrey T. Morisette, Xiaoyang Zhang

GSCE Faculty Publications

Cross comparison of satellite-derived land surface phenology (LSP) and ground measurements is useful to ensure the relevance of detected seasonal vegetation change to the underlying biophysical processes. While standard 16-day and 250-m Moderate Resolution Imaging Spectroradiometer (MODIS) vegetation index (VI)-based springtime LSP has been evaluated in previous studies, it remains unclear whether LSP with enhanced temporal and spatial resolutions can capture additional details of ground phenology. In this paper, we compared LSP derived from 500-m daily MODIS and 30-m MODIS-Landsat fused VI data with landscape phenology (LP) in a northern U.S. mixed forest. LP was previously developed from intensively observed …

Exploring The Preservation Of Pastoralism And The Natural World In Western Mongolia , Josephine Brownell

Independent Study Project (ISP) Collection

At a time when Mongolia is experiencing the intense effects of land degradation, human activity, and climate change, it is crucial that a new land management framework is developed with conservation in mind. Pastoralism’s unique relationship with the land serves as a method of protecting the natural world for the future. This study focuses on a pastoral community in Western Mongolia while considering a main research question: Is a herder’s historically deep connection with the land enough to protect the modern pastoral lifestyle in Mongolia for years to come? In answering this question, a review of related previous studies on …

Station Exposure And Resulting Bias In Temperature Observations: A Comparison Of He Kentucky Mesonet And Asos Data, James Kyle Thompson

Masters Theses & Specialist Projects

Station siting, exposure, instrumentation, and time of observations influence longterm climatic records. This thesis compared and analyzed temperature data from four Kentucky Mesonet stations located in Fayette (LXGN), Franklin (LSML), Clark (WNCH), and Bullitt (CRMT) counties to two nearby Automated Surface Observation Systems (ASOS) stations in Kentucky. The ASOS stations are located at Louisville International Airport (Standiford Field - KSDF) and at Lexington Airport (Blue Grass Field - KLEX). The null hypothesis states that there is no significant difference in temperature measurements between the two types of stations. To quantify the differences in temperature measurements, geoprofiles and the following statistical …

Master's Theses

Horn Island is part of the MS/AL barrier island chain in the northern Gulf of Mexico located approximately 18kn off the coast of Mississippi. This island’s habitats have undergone many transitions over the last several decades. The goal of this study was to quantify habitat change over a seventy year period using historical black and white photography from 1940. Using present NAIP imagery from the USDA, habitat structure was estimated by using geo-statistics, and second order statistics, from a co-occurrence matrix, to characterize texture for habitat classification. Percent land cover was then calculated to determine overall land cover change over …

The Influence Of The Projected Coordinate System On Animal Home Range Estimation Area, Michael Barr

USF Tampa Graduate Theses and Dissertations

Animal home range estimations are important for conservation planning and protecting the habitat of threatened species. The accuracy of home range calculations is influenced by the map projection chosen in a geographic information system (GIS) for data analysis. Different methods of projection will distort spatial data in different ways, so it is important to choose a projection that meets the needs of the research. The large number of projections in use today and the lack of distortion comparison between the various types make selecting the most appropriate projection a difficult decision. The purpose of this study is to quantify and …

Restoration Of Bison (Bison Bison) To Agate Fossil Beds National Monument, A Feasibility Study, Daniel S. Licht

United States National Park Service: Publications

Executive Summary

Agate Fossil Beds National Monument is a 3,057-acre park located in western Nebraska. The unit is comprised of northern mixed-grass prairie vegetation, typical of the Northern Great Plains. Weather, fire, and grazing are generally considered to be the ecological drivers of prairie ecosystems and critical for prairie health. However, grazing has essentially been absent since the 1960s. In 2014, a Department of the Interior report explicitly listed the park as a high priority for bison restoration. This report evaluates the feasibility, management options, benefits, and challenges of restoring bison to Agate Fossil Beds National Monument.

Stream Temperature Management In The Tualatin Watershed: Is It Improving Salmonid Habitat?, Raymond Banks Hennings

Geography Masters Research Papers

The purpose of this paper is to examine the literature from scientific and governmental entities that describes the problems with elevated stream temperatures in the Tualatin basin, the actions being taken to resolve those problems, and to assess whether these actions are meeting the goal of improving salmonid habitat in the basin. Elevated stream temperatures are considered a pollutant under the US Clean Water Act (Clean Water Act 1972, as amended) because increased stream temperatures can be harmful to native aquatic biota, particularly salmonid fish species that have evolved to use cold water (IMST 2004).

Evaluating The Effectiveness Of Regulatory Stormwater Monitoring Protocols On Groundwater Quality In Urbanized Karst Regions, Daniel C. Nedvidek

Masters Theses & Specialist Projects

Non-point pollution from stormwater runoff is one of the greatest threats to water quality in the United States today, particularly in urban karst settings. In these settings, the use of karst features and injection wells for stormwater management results in virtually untreated water being directed into the karst aquifer. Currently, no policies exist specifically to provide water quality protections to karst environments. This study utilized a combination of karst stormwater quality data, along with survey data collected from MS4 Phase II communities, and an analysis of current federal, local, and state water quality regulations, to assess the need for karst-specific …
