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 |

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 |

Seger, Jon | Natural history and evolution of paper-wasps | Paper-wasps occupy a special place in the history of animal behavior. Temperate species o f Polistes are large, beautiful, intelligent, adaptable, easy to observe, and thoroughly committed to social life. They are also aptly named, being intensely political, in the limited sense that any nonhuman an... | Individuals; Excellent; Phylogeny | 1997 |

Clayton, Dale H. | Coevolutionary history of ecological replicates: comparing phylogenies of wing and body lice to Columbiform hosts | Phylogenies depict the history of speciation for groups of organisms. Comparing the phylogenies of interacting groups can reveal instances of tandem speciation, or "cospeciation" (Brooks and McLennan, 1991; Hoberg et al., 1997; Paterson and Gray, 1997). Understanding the conditions under which cosp... | Feather lice; Wing lice; Body lice; Cospeciation | 2003 |

Clayton, Dale H.; Rogers, Alan R. | Genetic analysis of lice supports direct contact between modern and archaic humans | Parasites can be used as unique markers to investigate host evolutionary history, independent of host data. Here we show that modern human head lice, Pediculus humanus, are composed of two ancient lineages, whose origin predates modern Homo sapiens by an order of magnitude (ca. 1.18 million years). | Pediculus humanus; Head lice; Molecular phylogeny; Phthirus | 2004 |

Clayton, Dale H. | Ecological basis of coevolutionary history | Macroevolutionary patterns are difficult to interpret because they are the product of a time scale so vast that deterministic and chance events are hard to distinguish. Although the macroevolutionary history of a group can be reconstructed from extant species, determining the ecological context in ... | | 2003 |

Seger, Jon | Evolution of individuality by Leo W. Buss | Metazoans seldom reproduce vegetatively; they often die of cancer; and they almost always sequester their germ lines. Plants often reproduce vegetatively, seldom die of cancer, and almost never sequester a germ line. Buss argues that these and many other patterns can all be understood in a unified w... | Cell lines; Hierarchy; Biology | 1988 |

Seger, Jon | Solitary wasps: behavior and natural history by Kevin M. O'Neill | Most species of living things are insects, and ter- restrial ecology consists largely of interactions between insects and plants. The biologies of major insect groups such as Hymenoptera should be well documented and well known. Amazingly, they are not. The world is awash in excellent reviews of cur... | Insects; Ecological | 2002 |

Coley, Phyllis D. | Herbivory and defensive characteristics of tree species in a lowland tropical forest | Rate of herbivory and defensive characteristics of young and mature leaves were measured for saplings of 46 canopy tree species in a lowland tropical rain forest (Barro Colorado Island, Panama). Grazing rates were determined in the field for sample periods in the early wet, late wet, and dry seasons... | Fiber; Herbivory; Life history; Panama; Phenolics; Plant growth; Spatial distribution; Tannins; Temporal distribution; Treefall gaps; Tropical forest | 1983 |

Clayton, Dale H. | Influence of bill shape on ectoparasite load in Western Scrub-Jays | Populations of the Western Scrub-Jay (Aphelocoma californica) have bills specialized for feeding in their respective habitats. Populations in oak habitat have hooked bills, whereas those in pinyon habitat have pointed bills with a reduced maxillary overhang. Work on other bird species shows that the... | Ectoparasite load; Bill shape; Aphelocoma californica | 2002 |

Clayton, Dale H. | Neotropical tineidae, II: biological notes and descriptions of two new moths phoretic on spiny pocket mice in Costa Rica (Lepidoptera: Tineoidea) | Two new species of tineid moths discovered riding on the backs of two species of spiny pocket mice (Heteromyidae) in Costa Rica are described. Amydria selvae, new species, was found on Heteromys desmarestianus Gray in the rainforest at Finca La Selva and Ptilopsaltis santarosae, new species, occurr... | Neotropical Tineidae; Phoretic moths; Amydria selvae; Heteromys desmarestianus; Ptilopsaltis santarosae; Liomys salvini; Mouse moths | 1986 |

(C.) bartoni from the Philippine swiftlet, A. mearnsi (Oberholser), from the Philippines are described and illustrated.

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 |

Cieri, Robert | New insight into the evolution of the vertebrate respiratory system and the discovery of unidirectional airflow in iguana lungs | The generally accepted framework for the evolution of a key feature of the avian respiratory system, unidirectional airflow, is that it is an adaptation for efficiency of gas exchange and expanded aerobic capacities, and therefore it has historically been viewed as important to the ability of birds ... | | 2014-11-17 |

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.

Clayton, Dale H.; Bush, Sarah Elizabeth | Comparative transmission dynamics of competing parasite species | Competition-colonization trade-off models explain the coexistence of competing species in terms of a trade-off between competitive ability and the ability to colonize competitor-free patches of habitat. A simple prediction of these models is that inferior competitors will be superior dispersers.
