26 Sekercioglu, CaganPromoting community-based bird monitoring in the tropics: conservation, research, environmental education, capacity-building, and local incomesLong-term, locally-based biodiversity monitoring programs are essential for understanding and mitigating the effects of global change on tropical biodiversity while providing capacity-building, environmental education, and public outreach. However, these programs are lacking in most tropical countri...2011-01-01
27 Hultine, KevinEcohydrological implications of woody plant encroachmentIncreases in the abundance or density of woody plants in historically semiarid and arid grassland ecosystems have important ecological, hydrological, and socioeconomic implications. Using a simplified water-balance model, we propose a framework for conceptualizing how woody plant encroachment is li...Carbon cycling; ecohydrology; evapotranspiration2005
28 Nicoll, Kathleen; Chan, Marjorie A.; Jewell, PaulBonneville basin analogues for large lake processes & chronologies of geomorphic development on MarsPleistocene Lake Bonneville was a large (~50,000 sq km) terrestrial closed lake system in Utah, USA that developed during the Last Glacial Maximum (~20 ka BP), and persisted at highstand until a catastrophic outburst flood event ~17.4 ka cal BP and warming climate significantly lowered its volume [1...2009
29 Reichler, Thomas J.; Staten, Paul W.Use of radio occultation for long-term tropopause studies: uncertainties, biases, and instabilities.Research suggests that changes in tropopause structure can both indicate and impact changes in the global climate system. The Global Positioning System radio occultation (RO) technique shows tremendous potential for monitoring the global tropopause due to its precision, temporal consistency, and ...Radio occultation; Tropopause; Climate2007
30 Garrett, Timothy J.Gains in economic energy efficiency as the impetus for increasing atmospheric carbon dioxideGrowth of anthropogenic carbon dioxide (CO2) emissions is frequently diagnosed as a product of population, per capita economic production, the energy intensity of economic production (or inverse of its energy efficiency), and the carbon intensity of energy. This paper introduces an alternative, p...carbon dioxide, energy efficiency, economics2007-12-17

32 Garrett, Timothy J.No way out? the double-bind in seeking global prosperity alongside mitigated climate changeIn a prior study (Garrett, 2011), I introduced a simple economic growth model designed to be consistent with general thermodynamic laws. Unlike traditional economic models, civilization is viewed only as a well-mixed global whole with no distinction made between individual nations, economic sectors,...2012-01-01
33 Ehleringer, James R.Carbon isotope ratios in belowground carbon cycle processesAnalyses of carbon isotope ratios (δ13C) in soil organic matter (SOM) and soil respired CO2 provide insights into dynamics of the carbon cycle. δ13C analyses do not provide direct measures of soil CO2 efflux rates but are useful as a constraint in carbon cycle models. In many cases, δ13C analyses...Below ground processes; Ecosystems; Carbon cycle; Carbon isotope ratio; Ecosystem processes; Global change; Soil organic carbon; Soil organic matter2000
34 Sekercioglu, CaganCorrelates of elevational specialisation in Southeast Asian tropical birdsThe understanding of elevational selectivity in extremely rich tropical biotas is critical to the study of accelerating human-mediated environmental changes (e.g., deforestation and global climate warming). This paper explores the characteristics of Southeast Asian birds that are altitudinal special...2012-01-01
35 Malinowski, NicholasImproving water heaters for sustainabilityBuildings use about 40% of the total U.S. energy demand. Water heaters provide hot water for a variety of building uses including sinks, showers, dishwashers, washing machines, and space heating. Water heaters are the second most energy intensive appliances in a common household. Typically a home...Water heaters; Energy efficiency; Electricity; Emissions; Natural gas2018
36 Sekercioglu, CaganMeasuring the meltdown: drivers of global amphibian extinction and declineHabitat loss, climate change, over-exploitation, disease and other factors have been hypothesised in the global decline of amphibian biodiversity. However, the relative importance of and synergies among different drivers are still poorly understood. We present the largest global analysis of roughly ...2008-01-01
37 Reichler, Thomas J.Multidecadal drought cycles in the Great Basin recorded by the Great Salt Lake: modulation from a transition-phase teleconnectionThis study investigates the meteorological conditions associated with multidecadal drought cycles as revealed by lake level fluctuation of the Great Salt Lake (GSL). The analysis combined instrumental, proxy, and simulation datasets, including the Twentieth Century Reanalysis version 2, the North Am...2012-01-01
38 Hultine, Kevin; Sperry, John S.Transpiration and hydraulic strategies in a piñon-juniper woodlandAnthropogenic climate change is likely to alter the patterns of moisture availability globally. The consequences of these changes on species distributions and ecosystem function are largely unknown, but possibly predictable based on key ecophysiological differences among currently coexisting species...Drought; Hydraulic transport model; Juniperus osteosperma; Plant water use; Sap flux; Species distributions2008
39 Sekercioglu, CaganImportance of Ethiopian shade coffee farms for forest bird conservationCoffee is the most important tropical commodity and is grown in high-priority areas for biological conservation. There is abundant literature on the conservation value of coffee farms internationally, but there has been little research on this topic in Africa. Ethiopia is a diverse and little-studie...2014-01-01
40 Newton, MariaYouth perceptions of a caring climate, emotional regulation and psychological well-beingThe purpose of this study was to examine the meditational effect of perceived affective self-regulatory efficacy on the relationship between youth sport participants? perceived caring climate and their mental well-being. Three hundred and 95 participants (mean age = 11.80 ? 1.54) from a National Yo...2009
41 Golden, Kenneth M.Climate change and the mathematics of transport in sea iceAs the boundary layer between the ocean and atmosphere in the polar regions, sea ice is a critical component of the global climate system. As temperatures on Earth have warmed, the Arctic sea ice pack in particular has exhibited a dramatic decline in its summer extent. Indeed, the polar sea-ice pack...Polar ice; Fluid flow; Complex permittivity2009
42 Groth, Cori AnnSix factors of successful school improvement: blueprint for reform or process for continual school improvement?The last two decades have brought considerable attention to schoolwide improvements intended to raise student achievement-particularly in the area of literacy. In response to the emphasis on improved student achievement, many promising programs for school improvement have emerged. These programs, ...Schools; Student achievement; Literacy2000
43 Reichler, Thomas J.; Kim, JunsuUncertainties in the climate mean state of global observations, reanalyses, and the GFDL climate modelClimate research relies on realistic atmospheric data over long periods of time. Global reanalyses or observations are commonly used for this type of work.

44 Garrett, Timothy J.Are there basic physical constraints on future anthropogenic emissions of carbon dioxide?Global Circulation Models (GCMs) provide projections for future climate warming using a wide variety of highly sophisticated anthropogenic CO2 emissions scenarios as input, each based on the evolution of four emissions "drivers": population p, standard of living g, energy productivity (or efficiency...Global circulation models; Anthropogenic carbon dioxide emissions2009
45 Ehleringer, James R.Simplified GIS approach to modeling global leaf water isoscapesThe stable hydrogen (d2H) and oxygen (d18O) isotope ratios of organic and inorganic materials record biological and physical processes through the effects of substrate isotopic composition and fractionations that occur as reactions proceed.
