Sekercioglu, Cagan | Ibis quest | The day I arrived in Ethiopia, researcher Yilma Dellelegn Abebe of the Ethiopia Wildlife and Natural History Society (EWNHS) was just leaving the capital city, Addis Ababa, to search for three Northern Bald Ibises in a remote, roadless area of the country. These critically endangered birds had been ... | 2007-01-01 | |

Sekercioglu, Cagan | The worldwide variation in avian clutch size across species and space | Traits 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 | |

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 | |

Ehleringer, James R. | Simplified GIS approach to modeling global leaf water isoscapes | The 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. At large scales, these processes can exhibit spatial predic... | Oxygen isotope ratio; Hydrogen isotope ratio; Leaf water isoscapes; GIS | 2008 |
