Sekercioglu, Cagan | Impacts of birdwatching on human and avian communities | Ecotourism can be a vehicle for community-based conservation if it is conducted with an emphasis on the well-being of local ecosystems and human communities. Birdwatchers form the largest group of ecotourists, and are, on average, well-educated, wealthy and committed. This makes them ideal ecotouris... | | 2002-01-01 |

Sekercioglu, Cagan | Birding economics: conservation through commodification | In the long-run, the quality of our birding (and the length of our lists) depends on our success in conserving birds and their habitats. Who would not love to see a Labrador Duck during a pelagic trip, have Carolina Parakeets fly overhead on a CBC, or photograph a Bachman's Warbler foraging in a can... | | 2003-01-01 |

Sekercioglu, Cagan | People skills for the conservation professional | Conservation scientists are increasingly becoming aware of the importance of the human aspects of conservation, and in conservation circles, ‘‘social science'' is the word of the day. There is a rapidly growing social science working group in the Society for Conservation Biology and it is hard t... | | 2008-01-01 |

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.

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 |

Sekercioglu, Cagan | The need to quantify ecosystem services provided by birds | What are birds worth-what is their actual dollar value to human society? To most of us in the ornithological community, birds are invaluable. But in these times we need more specific rationales to convince policy makers and business leaders to include bird conservation in land-use and development de... | | 2011-01-01 |

Adler, Frederick R. | Recent rapid increases in the right whale (Eubalaena australis) population off southern Brazil | Right whales (Eubalaena australis) that gather on a wintering ground off southern Brazil have been aerial surveyed and photographically identified since 1987. As of 2003 the Brazilian Right Whale Catalogue has 315 different individual whales of which 31 were resighted in other years (23 females, 3 y... | | 2005 |

Adler, Frederick R. | Role of heterogeneity in the persistence and prevalence of sin nombre virus in deer mice | Many diseases persist at a relatively low prevalence, seemingly close to extinction. For a chronic disease in a homogeneous population, reducing the transmission rate by a fraction proportional to the prevalence would be sufficient to eradicate the disease. This study examines how higher prevalence ... | Transmission; Survivorship; Seropositivity | 2008 |

Ehleringer, James R.; Belnap, Jayne | Sensitivity of the Colorado plateau to change: climate, ecosystems, and society | The 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 culture | 2008 |

Farmer, Colleen G. | Parental care: the key to understanding endothermy and other convergent features in birds and mammals | Birds and mammals share a number of features that are remarkably similar but that have evolved independently. One of these characters, endothermy, has been suggested to have played a cardinal role in avian and mammalian evolution. I hypothesize that it is parental care, rather than endothermy, that ... | Evolution; Metabolism; Convergence | 2000 |

Davidson, Diane W. | Dispersal adaptations of some acacia species in the Australian arid zone | Most Australian representatives of the genus Acacia have diaspores with arillate appendages indicative of adaptation for active dispersal by animals. Based on physical and chemical characteristics of these arils and mechanisms of diaspore presentation, a number of arid zone acacias can be distingu... | Acacia; Australian arid zone; Dispersal ecology; Fruit quality; Myrmecochory; Ornithochory; Seed parasitoids; Soil nutrients | 1984 |

Clayton, Dale H. | Molecular phylogeny of the dove genus Zenaida: mitochondrial and nuclear DNA sequences | We reconstructed a phylogeny for the seven species of doves in the genus Zenaida on the basis of a combined analysis of mitochondria (ND2 and cytochrome b) and nuclear (fibrinogen intron 7) DNA sequences. This phylogeny, which is completely resolved, is well supported with all nodes showing greater... | Molecular phylogeny; Dove; Nuclear DNA | 2000 |

Coley, Phyllis D. | What's up? Perspectives from the first international forest canopy conference at Sarasota, Florida, 1994 | Jumars, caribineers, pole pruners, tree bicycles, Bosun's chairs, booms, peconhas . . . these terms are not listed in most biological dictionaries. Nor are construction cranes or large treehouses or hot-air dirigibles listed as priority equipment for any scientific laboratories. But these are th... | | 1995 |

Ehleringer, James R.; Cerling, Thure E.; Dearing, Maria-Denise | Experimental study of carbon-isotope fractionation between diet, hair, and feces of mammalian herbivores | The carbon-isotope composition of hair and feces offers a glimpse into the diets of mammalian herbivores. It is particularly useful for determining the relative consumption of browse and graze in tropical environments, as these foods have strongly divergent carbon-isotope compositions. Fecal ?13C v... | Fractionation; Mammalian herbivores; Medicago sativa; Cynodon dactylon | 2003 |

Farmer, Colleen G. | The provenance of alveolar and parabronchial lungs: insights from paleoecology and the discovery of cardiogenic, unidirectional airflow in the American alligator (Alligator mississippiensis) | Birds and mammals evolved greater aerobic abilities than their common ancestor had. This required expansion of the cardiopulmonary system's capacity for gas exchange, but while directional selection for his expanded capacity resulted in extremely similar avian and mammalian hearts, strikingly differ... | | 2010-07 |

Sekercioglu, Cagan | Chewing lice (Phthiraptera) species found on Turkish shorebirds (Charadriiformes) | Approximately 4.500 species of lice have been so far described, with about 4.000 species seen on birds and with 3.000 species in the suborder Ischnocera 1. There are 465 bird species so far recorded in Turkey and the actual total is likely to exceed 500 species. However, the chewing lice fauna of th... | | 2010-01-01 |

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.

Ehleringer, James R. ; Cerling, Thure E. | Aberrant water homeostasis detected by stable isotope analysis | While isotopes are frequently used as tracers in investigations of disease physiology (i.e., 14C labeled glucose), few studies have examined the impact that disease, and disease-related alterations in metabolism, may have on stable isotope ratios at natural abundance levels.

Farmer, Colleen G. | Right-to-left shunt of crocodilians serves digestion | All amniotes except birds and mammals have the ability to shunt blood past the lungs, hut the physiological function of this ability is poorly understood. We studied the role of the shunt in digestion in juvenile American alligators in the following ways. First, we characterized the shunt in fasting... | Postprandial; Alligators; Gastrointestinal | 2008 |
