76 Forster, Richard R.Prevalence of pure versus mixed snow cover pixels across spatial resolutions in alpine environmentsRemote sensing of snow-covered area (SCA) can be binary (indicating the presence/absence of snow cover at each pixel) or fractional (indicating the fraction of each pixel covered by snow). Fractional SCA mapping provides more information than binary SCA, but is more difficult to implement and may no...2014-01-01
77 Coley, Phyllis D.; Kursar, Thomas A.Pests vs. drought as determinants of plant distribution along a tropical rainfall gradientUnderstanding the mechanisms that shape the distribution of organisms can help explain patterns of local and regional biodiversity and predict the susceptibility of communities to environmental change. In the species-rich tropics, a gradient in rainfall between wet evergreen and dry seasonal forests...Drought tolerance; Herbivory; Panama; Pathogen attack; Rainfall gradient; Tree distribution; Tropical forests2009
78 Jewell, PaulControls of tufa development in Pleistocene Lake Bonneville, UtahProminent tufa localities along the Provo level (∼14,000 14C yr B.P.) shoreline in Pleistocene Lake Bonneville have been characterized in detail. Three types of tufa are recognized: capping tufa, beachrock, and capping tufa over beachrock. Capping tufa and beachrock are end members of a continuum ...Tufa; Pleistocene; Pluvial lakes2006
79 Lucich, Stephen; Smith, AmandaEstimating building CO2 emissions reductions with EnergyPlusThe aim of this research is to investigate the potential to reduce greenhouse gas (GHG) emissions from the buildings sector in the Salt Lake Valley by altering the operational strategies of existing buildings.

80 Zick, Cathleen D.Does daylight savings time encourage physical activity?Background: Extending Daylight Savings Time (DST) has been identified as a policy intervention that may encourage physical activity. However, there has been little research on the question of if DST encourages adults to be more physically active. Methods: Data from residents of Arizona, Colorado, Ne...2014-01-01

Spatial and temporal variations of canopy CO2 con...Carbon isotopes; Pacific silver fir; Carbon budget; Soil respiration; Cascade Mountains1998
83 Codding, BrianCodding, Brian: Living outside the box: An updated perspective on diet breadth and sexual division of labor in the Prearchaic Great Basin [Author's Manuscript]A tremendous amount has been learned about the Prearchaic (before 9000 BP) Great Basin since we advocated a perspective of sexual division of labor based on Human Behavioral Ecology a decade ago. Many investigators have taken our advice and a few have challenged our assumptions and inferences. One o...2014-01-01
84 Codding, Brian F.Explaining prehistoric variation in the abundance of large prey: a zooarchaeological analysis of deer and rabbit hunting along the Pecho Coast of Central CaliforniaThree main hypotheses are commonly employed to explain diachronic variation in the relative abun dance of remains of large terrestrial herbivores: (1) large prey populations decline as a function of anthro pogenic overexploitation; (2 ) large prey tends to increase as a result of increasing social p...Foraging; Resource depression; Prestige hunting; Paleoclimatic variability; Human behavioral ecology; Zooarchaeology; Central California2009-11-14
85 Solomon, Douglas KipEvaluating the use of strontium isotopes in tree rings to record the isotopic signal of dust deposited on the Wasatch MountainsDust cycling from the Great Basin to the Rocky Mountains is an important component of ecological and hydrological processes. We investigated the use of strontium (Sr) concentrations and isotope ratios (87Sr/86Sr) in tree rings as a proxy for dust deposition. We report Sr concentrations and isotope r...2014-01-01
86 Sekercioglu, CaganThe worldwide variation in avian clutch size across species and spaceTraits such as clutch size vary markedly across species and environmental gradients but have usually been investigated from either a comparative or a geographic perspective, respectively. We analyzed the global variation in clutch size across 5,290 bird species, excluding brood parasites and pelagic...2008-01-01
87 O'Rourke, Dennis H.Introduction: origins and settlement of the indigenous populations of the Aleutian ArchipelagoThe series of papers in this special issue of Human Biology use an interdisciplinary approach to address regional questions and to integrate disparate Aleutian data into a broad, synthetic effort. The contributors leverage decades of data on Aleut origins, biogeography, and behavior through integrat...2010
88 Pounder, Diana G.Theory to practice: a description and multi-dimensional evaluation of the University of Utah's educational administration Ed.D. programThe purpose of this paper is tp describe the University of Utah's recently revised Ed.D. program and to report the results of several program evaluation efforts conducted since i t s implementation. In particular, the most recent evaluation study assesses the effectiveness of the field-based doctora...1995
89 Blackwelder, Eliot; Hubbs, Carl L.; Miller, Robert R.; Antevs, ErnstThe Great Basin with emphasis on glacial and postglacial timesThe Great Basin is a physiographic province the boundaries o f which are somewhat indefinite. Roughly it lies between the Sierra Nevada on the west and the Wasatch Mountains on the east, but its tributary valleys extend over into Wyoming. To the north it grades into the Columbia lava plateau, and to...1948-06-30
90 Kumpfer, KarolEffectiveness of a culturally adapted strengthening families program 12-16 years for high-risk Irish familiesBACKGROUND: Evidence-based programs (EBPs) targeting effective family skills are the most cost effective for improving adolescent behavioural health. Cochrane Reviews have found Strengthening Families Program (SFP) to be the most effective substance abuse prevention intervention. Standardized cultur...2012-01-01
91 Ehleringer, James R.; Negus, Norman C.Red Butte Canyon Research Natural Area: history, flora, geology, climate, and ecologyRed Butte Canyon is a protected, near pristine canyon entering Salt Lake Valley, Utah. It contains a well-developed riparian zone and a perennial stream; hillside vegetation ranges from grasslands on the lower limits to Douglas-fir and aspen stands at the upper elevations.

94 Ehleringer, James R.Plant adaptation in the Great Basin and Colorado PlateauAdaptive features of plants of the Great Basin are reviewed. The combination of cold winters and an arid to semiarid precipitation regime results in the distinguishing features of the vegetation in the Great Basin and Colorado Plateau. The primary effects of these climatic features arise from how t...Plant adaptation; Great Basin; Colorado Plateau; Cold deserts1992
95 Broughton, JohnHomestead cave IchthyofaunaBiological evidence on the climatic and hydrographic history of the intermountain region would be much richer, if we had more than the present dribble of paleontological data on the fishes (Hubbs and Miller, 1948, p. 25). In this passage from their landmark synthesis of historical fish biogeograph...Homestead Cave; Ichthyofauna; Lake Bonneville2000
96 Ehleringer, James R.Oxygen isotope ratios of waters and respired CO2 in Amazonian forest and pasture ecosystemsThe oxygen isotope ratio (d18O, SMOW) of atmospheric CO2 is a powerful indicator of large-scale CO2 exchange on land. Oxygen isotopic exchange between CO2 and water in leaves and soils controls the d18O of atmospheric CO2. Currently there is little empirical information on the spatial and temporal ...Amazonia; Carbon dioxide (CO2); Oxygen isotope ratio; Photosynthesis; Respiration; Stable isotope ratio; Tropical forests2005
97 Wolfinger, Nicholas H.Marriage and divorce in Utah and the United States: convergence or continued divergence?The social context for marriage and divorce in the United States has changed dramatically over the last 50 years. Since the 1950s, Americans have been waiting longer to marry. Women's median age at first marriage rose from 20 in the 1960s to 25 in 2000; for men, the increase was from 22 to 27 (Clar...2006
98 Coley, Phyllis D.On tropical forests and their pestsBiologists have long been intrigued by the diversity of tropical forests, where 1 hectare may hold more than 650 tree species-more than in all of Canada and the continental United States. Eco- logical theory suggests that if species are too similar in their resource use, one will out- compete the ot...2014-01-01
