1 Ehleringer, James R.Implications of CO2 pooling on δ13C of ecosystem respiration and leaves in Amazonian forestThe carbon isotope of a leaf (δ13Cleaf) is generally more negative in riparian zones than in areas with low soil moisture content or rainfall input. In Central Amazonia, the small-scale topography is composed of plateaus and valleys, with plateaus generally having a lower soil moisture status ...Amazonia; Carbon dioxide; Oxygen isotope ratio; Respiration; Soil water content2008
2 Brown, Francis HaroldSome early pleistocene deposits of the lower Omo valley: the Usno formationEarly Pleistocene deposits of the Rudolf Basin have been described by E. Brumpt (Bourg de Bozas, 1903: 107 ff.), Arambourg (1943: 190 ff.), Fuchs (1939), Patterson (1966), and Butzer and Thurber (1969). These include the Omo Beds, first recognized by Brumpt in 1902 and subsequently studied by Arambo...1969
3 Bowling, David R.Impacts of anthropogenic emissions and cold air pools on urban to montane gradients of snowpack ion concentrations in the Wasatch Mountains, UtahUrban montane valleys are often characterized by periodic wintertime temperature inversions (cold air pools) that increase atmospheric particulate matter concentrations, potentially stimulating the deposition of major ions to these snow-covered ecosystems. We assessed spatial and temporal patterns o...2014-01-01
4 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
5 Hawkes, KristenHadza scavenging: implications for Plio/Pleistocene Hominid subsistenceThe frequent association of stone tools and large animal bones in African Plio/Pleistocene archaeological sites has long been taken as evidence of the importance of hunting in early hominid diets. Many now argue that it reflects hominid scavenging, not hunting.Hadza; Scavenging; Plio/Pleistocene; Hominid Diet1988-04
6 Adams, DanielMicrobial production of methane and carbon dioxide from lignite, bituminous coal, and coal waste materialsThe aim of this study was to examine microbial methane and CO2 production from bituminous coal waste, lignite, and bituminous coal materials. Bituminous coal and coal waste material were obtained from a Utah mine and lignite was obtained from a commercially available North Dakota sample. Microbial p...2012-01-01
7 Ehleringer, James R.ENSO effects on primary productivity in Southern Atacama desertIn the winter-rain southern Atacama Desert of the Coquimbo Region of Chile, El Niño - Southern Oscillation (ENSO) events modulate primary productivity. In this region, there are important changes in water availability between La Niña (dry) and El Niño (rainy) years. Using interannual comparison...El Niño; Atacama Desert; Terrestrial ecosystems; Plant productivity2006
8 Flowers, SevilleFerns of UtahThe distribution of many species of our ferns is not well known in Utah. Collectors have centered their work around certain localities and many blank spots appear on the distributional map. One might presume certain species to be present in some of these unexplored areas but specimens are still to b...1944-11-15
9 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
10 Behle, William H.Birds of pine valley mountain region, Southwestern UtahIt has long been a practice among ornithologists to study the distribution, variation, and ecological relationships of birds in areas characterized by diverse physiographic features. Such studies are motivated usually by the desire to aid in finding solutions for the many problems concerning the dis...1943-08-10
11 Bohs, Lynn A.New species of Solanum section Cyphomandropsis (Solanaceae) from BoliviaA new species of Solanum sect. Cyphomandropsis (Solanaceae), S. hibernum, is described from the western part of Dept. Santa Cruz, Bolivia. Its strongly discolorous leaves densely covered below with white dendritic hairs distinguish it from the other species in the section.Solanum hibernum; Cyphomandropsis1994
12 Ehleringer, James R.Population- and family-level variation of brittlebush (Encelia farinosa, Asteraceae) pubescence: its relation to drought and implications for selection in variable environmentsBecause leaf pubescence of the desert shrub Encelia farinosa increases in response to drought and influences photosynthesis and transpiration, we hypothesized that differences in water availability across the range of this species may result in genetic differentiation for pubescence and associated p...Encelia farinose; Absorptance; Adaptation; Asteraceae; Desert; Drought acclimation; Leaf pubescence; maternal family variance; spatiotemporal heterogeneity2003

14 Davidson, Diane W.Effects of trenching on growth and survival of planted Shorea parvifolia seedlings under pioneer stands in a logged-over forestEffects of trenching on growth and survival of planted Shorea parvifolia seedlings under pioneer stands in a logged-over forest. We conducted an experiment to determine the value of trenching in reducing potentially negative effects of root competition on growth of Shorea parvifolia seedlings plant...Shorea parvifolia; Trenching; Dipterocarp seedlings; Enrichment planting; Pioneer stands; Root competition; Soil compaction; Sabah1998
15 Behle, William H.The birds of the deep Creek Mountains of Central Western UtahIn furtherance of a long-time survey of the avifauna of Utah the Deep Creek Mountain region of the central western part of the state was chosen as an area for intensive study. It was expected that gradients would occur in the characters of geographically variable birds between populations from the i...1955-01-10
16 Cottam, Walter P.New and extended ranges for Utah PlantsThe following Utah plan ts are not included in Tidestrom's " Flora of Utah and Nevada," nor are any listed specifically for Utah in Rvdberg's " Flora of the Rocky Mountains and A djacent Plains."

18 Flowers, SevilleThe hepaticae of UtahThe Hepaticae, or liverworts, are small green plants mostly growing in damp or wet places, although a considerable number of them inhabit dry shady places, even in desert regions. As a whole, they are inconspicuous and, together with the mosses, lichens and other primitive forms of plant life, occup...1961-05-30
19 Ehleringer, James R.; Belnap, JayneSensitivity of the Colorado plateau to change: climate, ecosystems, and societyThe Colorado Plateau is located in the interior, dry end of two moisture trajectories coming from opposite directions, which have made this region a target for unusual climate fluctuations. A multidecadal drought event some 850 years ago may have eliminated maize cultivation by the first human settl...Colorado Plateau; Biological crust; Climate change; Megadrought; Ranching; Dry crop productivity; Extractive industries; Pueblo Indians; Fremont culture2008
20 Durrant, Stephen D.The distribution and taxonomy of Kangaroo rats (genus dipodomys) of UtahThe first comprehensive work on the mammals of Utah was published by Barnes in 1922. In this work (Barnes 1922:86-87) only two kangaroo rats were known from the confines of the state. They were known at that time as Perodipus montcmus utahensis and Perodipus longipes. In Barnes revised edition (1927...1945-06-30
21 Eckhoff, David W.Drought happens: get used to it! Will technology help us to survive?Drought is not the most popular subject in the world. Actually, as opposed to death, I think there are some bright spots in the drought mitigation future. I will review some of these in this lecture, but I'm also going to discuss some of the downsides of drought, because you can't have one without t...Wastewater reclamation; Tiered water rates2002-09-10
