Mapping The Distribution Of Barrier Island Slash Pine Woodland And Determining Growth Responses Of Pinus Elliottii To Hurricane Katrina (2005) On Cat Island, Mississippi, William Richard Funderburk

Master's Theses

Barrier islands are ubiquitous features along the Atlantic and Gulf of Mexico North American coastline and are subjected disturbances such as extreme episodic events. The wind, waves, and storm surges of Hurricane Katrina heavily impacted the Mississippi–Alabama barrier island chain on August 29, 2005. Cat Island experienced a 7-m storm surge, the highest wind energy in the chain, but was estimated to have the least amount of forest mortality. The purpose of this study was to investigate the distribution of Pinus elliottii on Cat Island Mississippi and evaluate relationships of elevation with mean radial growth rate (mm y ̄ ˡ), …

The Influence Of The Projected Coordinate System On Animal Home Range Estimation Area, Michael Barr Nov 2014

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 …

Stream Temperature Management In The Tualatin Watershed: Is It Improving Salmonid Habitat?, Raymond Banks Hennings Nov 2014

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).

Estimation Of Forest Interior Condition In Southern Appalachian Mountains Using Airborne Lidar Data, Gang Shao, Songlin Fei, Buddhika D. Madurapperuma, Guofan Shao

Purdue GIS Day

Sustainability of forest ecosystem requires maintenance of forest cover and forest interior conditions. Sustaining forest cover supplies ecosystem goods and services and maintains biomass and carbon and nitrogen storage. Forest interior supports ecosystem functioning and provides particular physical and biological environments for plant and animal species that depend on a type of habitat isolated from non-forest land cover areas and prohibit the infestation of invasive species. Land cover maps derived from satellite imagery were broadly applied to assess spatial patterns of forest ecosystem and its dynamic. However, existing land cover maps at landscape scale are insufficient to provide information of …

Tablet-Based Mobile Gis Approaches To Archaeological Data Collection, Ian Lindsay Nov 2014

Tablet-Based Mobile Gis Approaches To Archaeological Data Collection, Ian Lindsay

Purdue GIS Day

Over the past 15 years, archaeological research in northern Armenia has documented the unique evolution of prehistoric complex societies in the South Caucasus, where complex, fortress-centered institutions emerged during the Late Bronze Age (c.1500-1150 BC) not from settled farming villages—as is more typical of archaic states—but from mobile herding communities. As the costs of archaeological fieldwork continue to rise, resulting in shorter and more intensive field seasons, researchers are leveraging new technologies to improve the efficiency and accuracy of data collection in the field. An increasingly popular solution in archaeology is the use of “paperless” site recording strategies that enhance …

The Emerging American Empire: Republican Capitalist Development In The Usa, 1830-1930, Richard Hogan Nov 2014

The Emerging American Empire: Republican Capitalist Development In The Usa, 1830-1930, Richard Hogan

Purdue GIS Day

Capital Accumulation, territorial expansion, and the rise and fall of political party systems mark the history of the American Empire, 1830-1930. During this time, the USA emerged from colonial dependency at the edge of the British Empire (after the War of 1812) and established a bipartisan political system (after the election of Jackson in 1828), which was destroyed by the irrepressible conflict between institutionalized Slavery and the challenge of Abolitionism, 1830-1860, culminating in the Civil War. After the election of 1860, a new bipartisan system and renewed industrial capitalist expansion (especially after the political storm from Reconstruction to Populism, 1876-1896) …
