1 Using species distribution models to quantify climate change impacts on the rosy-finch superspecies: an alpine obligateConrad, Edward C.Anthropogenic climate change is forcing plants and animals to respond by shifting their distributions poleward or upward in elevation. An organism's ability to track climate change is constrained if its habitat cannot shift and is projected to decrease in geographic extent. Geographic distributions ...Geography
2 The role of climate variability and disturbances on forest ecology in the intermountain westCarter, Vachel AshleyDisturbances play an integral role in regeneration and succession of many forested ecosystems in the Intermountain West region of the western United States. However, changes in climate have been shown to alter the occurrence, duration, and frequency of disturbances. The research presented here uses ...Geography
3 Climatic influences on two cienega complexes from northern baja california: a ~45,000 year paleoecological recordChavez, Vanessa GraceCiƩnegas are a type of specialized systems that are found in desert landscapes and characterized by organic-rich and waterlogged soils. The existence of these systems corresponds with stability of the hydrologic cycle in arid landscapes so that when they are active they serve as a dependable source...Geography
4 Examining vegetation phenology of Ugandan dambos using spectral mixture modeling fractionsGraves, Scott AndrewOrganic Matter (SOM). Lacking O2, micro-organisms decompose SOM through anaerobic decomposition, which in turn produces CH4. Because wetland soils are continually saturated, the organic matter is decomposed primarily by anaerobic means, which makes wetlands the primary source of naturally produce...Geography
5 Spatial representation in the social interaction potential metric: an analysis of scale and parameter sensitivityLi, XiaoThe Social Interaction Potential metric measures urban structural constraints on social interaction opportunities of a metropolitan region based on the time-geographic concept of joint accessibility. The current implementation of the metric utilizes an interaction surface based on census tracts and ...Geography
6 Neotropical climate, vegetation, and fire histories on local to regional scalesMaezumi, Shira YoshimiDuring the 21st century global change and deforestation have increased fires in the Amazon. Protection of rainforests and sustainable land-use practices in the Neotropics are critical for preserving biodiversity and buffering for climate. To make informed policy decisions it is necessary to understa...Geography
7 Bicycling preferences and behavior in salt lake cityFu, LiweiImproving our understanding of cycling behaviors in urban areas is an important step in producing a more sustainable transportation system. Based on a stated preference survey in Salt Lake City, Utah, this paper studies the influence of attitudes on bicycling behavior. A travel preference factor ana...Geography
8 Constraining the greenland firn aquifer's ability to hydrofracture a crevasse to the bed of the ice sheetMcnerney, LauraSpanning 1.7 million km2 with glacial ice that exceeds 3,000 m thick in the interior, the Greenland ice sheet plays a large role in Earth's response to climate change. A recently discovered firn aquifer within the ice sheet has the potential to buffer or enhance sea level rise by retaining or output...Geography
9 Recent ice sheet snow accumulation and firn storage of meltwater inferred by ground and airborne radarsMiege, ClementRecent surface mass balance changes in space and time over the polar ice sheets need to be better constrained in order to estimate the ice-sheet contribution to sea-level rise. The mass balance of any ice body is obtained by subtracting mass losses from mass gains. In response to climate changes of ...Geography
10 Thinking inside the black box: enhancing the social vulnerability index with an artificial neural networkHile, Ryan PatrickThe Social Vulnerability Index (SoVI) has served the hazards community well for more than a decade, but it is based on linear statistical methods. Using Utah as a test case, a state with a population exposed to a variety of hazards, this study sought to build upon the SoVI approach by augmenting it ...Geography

19 Hyperspectral remote sensing for monitoring species-specific drought impacts in Southern CaliforniaCoates, Austin ReeceA drought persisting since the winter of 2011-2012 has resulted in severe impacts on shrublands and forests in southern California, USA. Effects of drought on vegetation include leaf wilting, leaf abscission, and potential plant mortality. These impacts vary across plant species, depending on diff...Geography
20 Evaluating the effects of spatial resolution on hyperspectral fire detection and temperature retrievalMatheson, Daniel ScottHyperspectral remote sensing of wildfires combines principles of emitted radiation with advanced spectrometry to model wildfire area and temperature, as well as background land cover classification, at the subpixel level. Yet airborne hyperspectral sensors face problems of inconsistent spatial resol...Geography
21 The application of stable carbon isotopes as an enhanced method for statistical crossdating: a case study from Range Creek Canyon, UtahBares, RyanDendroarcheological samples pose a particular challenge when attempting to crossdate them against a master chronology. Previous attempts to accurately crossdate dendroarcheological samples from Range Creek Canyon have had limited success (Towner et al. 2009), due in part to the nonsignificance of th...Geography
22 Exploring the use of fine resolution nested ecological niche models to identify greater Sage-Grouse (Centrocercus Urophasianus) habitat and connectivity potential across a diverse landscapeBalzotti, Christopher StephenSuitable habitat for greater sage-grouse (Centrocercus urophasianus) has been greatly reduced over a relatively short ecological scale (1800s - Present). This reduction of habitat has had a negative impact on the current distribution and connectivity of the species. There has been work to map sage-g...Geography
23 Mapping species across multiple dates of hyperspectral imagery using iterative endmember selection and multiple endmember spectral mixture analysisDudley, KennethVegetation phenology results in seasonal changes in spectral reflectance. Phenology is often underutilized in hyperspectral vegetation mapping due to a lack of repeat imagery of the same region over time. Vegetation classification at the species level could benefit from introducing phenological info...Geography
24 Flow reversal events and statistical modeling of flow dynamics of hypersaline water across a constructed causeway, Great Salt Lake, Utah, USAFreeman, Michael LawrenceThe hypersaline Great Salt Lake (GSL), located in the western United States, is divided into a north arm (Gunnison Bay) and a south arm (Gilbert Bay) by a 29-km earth-filled railroad causeway completed in 1959. Flow between the two bays is restricted to an 88-m wide breach at the western end of the ...Geography
25 Observations of diurnal melt-freeze events using time domain reflectometry (TDR) in sesonal snowpackGold, BrittanyUnderstanding seasonal snowpack characteristics is essential for avalanche forecasting and water resource management.
