Sekercioglu, Cagan | Promoting community-based bird monitoring in the tropics: conservation, research, environmental education, capacity-building, and local incomes | Long-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 |

Hultine, Kevin | Ecohydrological implications of woody plant encroachment | Increases 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; evapotranspiration | 2005 |

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; Climate | 2007 |

Garrett, Timothy J. | Gains in economic energy efficiency as the impetus for increasing atmospheric carbon dioxide | Growth 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, economics | 2007-12-17 |

Garrett, Timothy J. | No way out? the double-bind in seeking global prosperity alongside mitigated climate change | In 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 |

Ehleringer, James R. | Carbon isotope ratios in belowground carbon cycle processes | Analyses 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 matter | 2000 |

Sekercioglu, Cagan | Correlates of elevational specialisation in Southeast Asian tropical birds | The 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 |

Malinowski, Nicholas | Improving water heaters for sustainability | Buildings 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 gas | 2018 |

Sekercioglu, Cagan | Measuring the meltdown: drivers of global amphibian extinction and decline | Habitat 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 |

Hultine, Kevin; Sperry, John S. | Transpiration and hydraulic strategies in a piñon-juniper woodland | Anthropogenic 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 distributions | 2008 |

Sekercioglu, Cagan | Importance of Ethiopian shade coffee farms for forest bird conservation | Coffee 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 |

Golden, Kenneth M. | Climate change and the mathematics of transport in sea ice | As 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 permittivity | 2009 |
