Microclimate Preferences Of The Grey-Headed Flying Fox (Pteropus Poliocephalus) In The Sydney Region, Stephanie T. Snoyman, Culum Brown

Sentience Collection

The population size of the grey-headed flying fox (Pteropus poliocephalus) has decreased dramatically as a result of a variety of threatening processes. This species spends a great proportion of time in roosting large social aggregations in urban areas, causing conflict between wildlife and humans. Little is known about why these bats choose to roost in some locations in preference to others. Roost selection by cave-dwelling bats can be greatly influenced by microclimatic variables; however, far less is known about microclimate selection in tree-roosting species despite the direct management implications. This study aimed to determine the microclimate characteristics of P. poliocephalus …

Population Survey (Census) Of Stray Dog Population In Ahmedabad, Gujarat, Rahul Sehgal, Sunil Chawla, Jack Reece

Stray and Feral Animal Populations Collection

Ahmadabad, the biggest city of Gujarat with a human population of approximately, 6 million. The rapidly expanding population of Ahmadabad means that the metropolitan region extends far outside from the confines of the old city. However, the development is rapid but uncontrolled. Therefore, there are a large number of areas that are prone to stray dogs and these areas are constantly increasing. The old methods of population control by strychnine poisoning or electrocution employed by the municipal corporations have not proved effective in controlling street dog populations, as new dogs soon migrate into the areas, where the local dog population …

Functional Upgrading Through Research And Development In The Czech Automotive Industry, Petr Pavlinek, Jan Ženka, Pavla Žížalová

Geography and Geology Faculty Proceedings & Presentations

Based on firm-level research and development (R&D) data, we evaluate the extent of functional upgrading in the Czech automotive industry between 1998 and 2008. The analysis draws on a unique database of 476 Czech-based automotive firms with 20 and more employees in the broadly defined automotive industry, a survey of 274 automotive firms and twenty-five in-depth company interviews. In addition to assessing changes in the extent of automotive R&D, we analyze the most important locational factors of automotive R&D in Czechia and its regional distribution in the country. We examine changes in the spatial concentration of automotive R&D between 1998 …

Subaerial Freshwater Stromatolites In Deer Cave, Sarawak – A Unique Geobiological Cave Formation, Joyce Lundberg, Donald A. Mcfarlane

WM Keck Science Faculty Papers

A suite of distinctive freshwater subaerial phosphatic stromatolites is developed close to the northeastern entrance of Deer Cave, Gunung Mulu National Park, Sarawak, Borneo, in conditions of very low light but ample supply of nutrients from guano. These stromatolites are not particulate; they are composed of alternating layers of more porous and more dense amorphous hydroxylapatite. This biomineralization occurs as moulds of coccoid (the majority) and filamentous (less abundant) cyanobacteria. Mineralization occurs at a pH of ~ 7.0 in the extracellular sheaths and in micro-domains of varying carbonate content in the surrounding mucus of the biofilm. The most recent surfaces …

Colorado's Large Snow Events' Impact On Tree Ring Growth And Dillon Reservoir, Katrina Leona Marzetta

Electronic Theses and Dissertations

Meteorological observations from 1894 through 2010 suggest that 17 historically large snow events occurred in the mountains of Colorado within Denver's water supply region. Of these 16 events, 14 can be identified in precipitation sensitive tree ring records as positive climatic pointer years. If these storms were to occur today, they would have the potential to fill reservoirs in Denver Water's supply system, even after years of sustained drought. These "drought busters" have the potential to refill Dillon Reservoir by increasing average yearly inflow up to 146% of the previous year's inflow. Such drought busters can help Denver recover from …

Earth- and space-based observations provide synergistic information for space mission encounters by providing data over longer timescales, at different wavelengths and using techniques that are impossible with an in situ flyby. We report here such observations in support of the EPOXI spacecraft flyby of comet 103P/Hartley 2. The nucleus is small and dark, and exhibited a very rapidly changing rotation period. Prior to the onset of activity, the period was ~16.4 hr. Starting in 2010 August the period changed from 16.6 hr to near 19 hr in December. With respect to dust composition, most volatiles and carbon and nitrogen isotope …

A Parallel Computing Approach To Fast Geostatistical Areal Interpolation, Qingfeng Guan, Phaedon Kyriakidis, Michael Goodchild

Geography Program: Faculty Publications

Areal interpolation is the procedure of using known attribute values at a set of (source) areal units to predict unknown attribute values at another set of (target) units. Geostatistical areal interpolation employs spatial prediction algorithms, i.e., variants of Kriging, which explicitly incorporate spatial autocorrelation and scale differences between source and target units in the interpolation endeavor. When all the available source measurements are used for interpolation, i.e., when a global search neighborhood is adopted, geostatistical areal interpolation is extremely computationally intensive. Interpolation in this case requires huge memory space and massive computing power, even with the dramatic improvement introduced by …

Nature, Domestic Labor, And Moral Community In Susan Fenimore Cooper's Rural Hours And Elinor Wyllys, Richard M. Magee

English Faculty Publications

Cooper's argument for a domestic ideal situated within a rural setting reinforces the importance of community connections through a shared sense of morality, as well as understanding of the natural world. Community alone—the human connections—never seems to be enough in Cooper's formulation, but must always exist with an awareness of the world outside the narrow confines of one's own domestic sphere. Concern for one's fellow-beings necessitates a concern for the world in which these beings live, and Cooper understands that when any bonds are broken—such as the bonds that connect us to the natural world—other bonds are threatened. Thus, when …

Evaluation Of Species Distribution Model Algorithms For Fine-Scale Container-Breeding Mosquito Risk Prediction, C. Khatchikian, Florencia Sangermano, D. Kendell, T. Livdahl

Geography

The present work evaluates the use of species distribution model (SDM) algorithms to classify high densities of small container-breeding Aedes mosquitoes (Diptera: Culicidae) on a fine scale in the Bermuda Islands. Weekly ovitrap data collected by the Department of Health, Bermuda for the years 2006 and 2007 were used for the models. The models evaluated included the algorithms Bioclim, Domain, GARP (genetic algorithm for rule-set prediction), logistic regression and MaxEnt (maximum entropy). Models were evaluated according to performance and robustness. The area under the receiver operating characteristic curve was used to evaluate each model's performance, and robustness was assessed according …

Social Disorganization And Sex Offenders In Minneapolis, Mn: A Socio-Spatial Analysis, Joseph Koncur

All Graduate Theses, Dissertations, and Other Capstone Projects

Using a combination of techniques stemming from the spatial analysis approach of Geography, structural-functionalist theory in Sociology, and an ecological perspective of Criminology, this thesis addresses where sex offenders reside and why. Analyses were performed using the twin cities of Minneapolis and St. Paul, Minnesota as a typical urban setting. The study fuses multiple disciplines work on the complex social problem of released risk level III sex offender management in a spatially-conscious, micro-scale analysis attempting to understand the distribution of released offenders and the relevance of social disorganization theory in explaining their distribution. Socio-economic status and family disruption are tested …

Minnesota River Basin Flood Mapping And Impact Assessment, Willy J. Mekeel

All Graduate Theses, Dissertations, and Other Capstone Projects

South Central Minnesota has experienced frequent flooding in the past because of the relatively flat topography, low elevation, and large amounts of snow melt in the spring. When these events happen, there is a large economic impact and potential health hazards to residents of the area. Having up-to-date flood zone maps can help residents be better prepared for emergency situations. Using Geographic Information Science (GIS), flood zone maps can be updated frequently in a more time efficient and inexpensive manner. Using a 30-meter digital elevation model (DEM) Compound Topographic Index (CTI) and Stream Power Index (SPI) layers were calculated for …

Mapping Time, Edward L. Ayers

History Faculty Publications

Our tools for dealing with terrestrial space are well-developed and becoming more refined and ubiquitous every day. GIS has long established its dominion, Google permits us to range over the world and down to our very rooftops, and cars and cell phones locate us in space at every moment. It is hardly surprising that geography and mapping suddenly seem important in new ways. Historians have always loved maps and have long felt a kinship with geographers. The very first atlases, compiled six hundred years ago, were historical atlases. But space and time remain uncomfortable—if ever-present and ever-active—companions in the human …

Tallgrass Prairie National Preserve, Vegetation Mapping Project [Poster], Kelly Kindscher, Hayley Kilroy, Jennifer Delisle, Quinn Long, Hillary Loring, Kevin Dobbs, Jim Drake

United States National Park Service: Publications

The Tallgrass Prairie National Preserve encompasses 10,894 acres in eastern Kansas, just north of Strong City. This park unit was created on November 12, 1996, and is the first to protect a nationally significant example of the once vast tall grass prairie ecosystem. Of the 400,000 square miles of tall grass prairie that once covered the North American continent, less than four percent remains, prin1arily in the Flint Hills. The park unit is primarily rocky upland prairies and deep-soiled prairies in the lowlands. It also contains some wet prairie ravines, riparian forests and some former cropland and restored prairie. These …
