Bohs, Lynn A. | Eggplant origins: out of Africa, into the Orient | The eggplant (Solanum melongena L.), also known as aubergine or brinjal, has been cultivated for centuries in the Old World and is currently a crop species of global importance. Despite this, hypotheses of eggplant evolution have been fraught with controversy. Previous conclusions have relied solely... | Eggplant origins; Crop domestication; Solanum melongena complex; Solanum incanum; DNA sequence; Africa; Asia | 2010 |

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 | Causes and consequences of bird extinctions | Increased human domination of the planet has caused the declines and extinctions of countless species. Each species has not only intrinsic value, but ecological functions of organisms are also essential for the integrity of ecosystems that allow people to benefit from essential free ecosystem servic... | | 2003-01-01 |

Sperry, John S. | Evaluation of Murray's law in Psilotum nudum (Psilotaceae), an analogue of ancestral vascular plants | Previous work has shown that the xylem of seed plants follows Murray's law when conduits do not provide structural support to the plant. Here, compliance with Murray's law was tested in the stem photosynthesizer Psilotum nudum, a seedless vascular plant. Psilotum nudum was chosen because the central... | Conduit furcation number; hydraulic architecture; Murray's law | 2005 |

Olivera, Baldomero M. | Novel Conus peptide ligand for K+ channels | Voltage-gated ion channels determine the membrane excitability of cells. Although many Conus peptides that interact with voltage-gated Na+ and Ca2+ channels have been characterized, relatively few have been identified that interact with K+ channels. We describe a novel Conus peptide that intera... | Conus peptides; Conotoxins | 2003 |

Shapiro, Michael D. | Genetic architecture of parallel armor plate reduction in threespine sticklebacks | How many genetic changes control the evolution of new traits in natural populations? Are the same genetic changes seen in cases of parallel evolution? Despite long-standing interest in these questions, they have been difficult to address, particularly in vertebrates. We have analyzed the genetic bas... | Genetic changes; Plate number; Genetic mapping | 2004 |

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 |

Shapiro, Michael D. | Divergence, convergence, and the ancestry of feral populations in the domestic rock pigeon | Domestic pigeons are spectacularly diverse and exhibit variation in more traits than any other bird species [1]. In The Origin of Species, Charles Darwin repeatedly calls attention to the striking variation among domestic pigeon breeds - generated by thousands of years of artificial selection on a s... | | 2010 |

Beckerle, Mary C. | Two muscle-specific LIM proteins in Drosophila | The LIM domain defines a zinc-binding motif found in a growing number of eukaryotic proteins that regulate cell growth and differentiation during development. Members of the cysteine-rich protein (CRP) family of LIM proteins have been implicated in muscle differentiation in vertebrates. Here we r... | LIM domains; Mlp60A; Mlp84B; Cysteine-rich proteins | 1996 |

Bohs, Lynn A. | Phylogeny and biogeography of the Canarian Solanum vespertilio and S. lidii (Solanaceae) | The endemic and rare Solanum vespertilio and S. lidii from the Canary Islands are notable in being andromonoecious, self compatible, highly heterandrous (with short >reward= anthers and one very long >pollination= anther), and bearing strongly zygomorphic corollas.

Saemundssonia procax (Kellogg and Chapman) is relegated to a new junior synonym of S... | Saemundssonia; Chewing lice; Saemundssonia boschi; Aethia pusilla; Phthiraptera | 2003 |

Yamaguchi, Ayako | Coding rate and duration of vocalizations of the frog , Xenopus laevis | Vocalizations involve complex rhythmic motor patterns, but the underlying temporal coding mechanisms in the nervous system are poorly understood. Using a recently developed whole-brain preparation from which "fictive" vocalizations are readily elicited in vitro, we investigated the cellular basis of... | | 2012-08-29 |

Capecchi, Mario R. | Illegitimate cre-dependent chromosome rearrangements in transgenic mouse spermatids. | The bacteriophage P1 Cre/loxP system has become a powerful tool for in vivo manipulation of the genomes of transgenic mice. Although in vitro studies have shown that Cre can catalyze recombination between cryptic "pseudo-loxP" sites in mammalian genomes, to date there have been no reports of loxP-si... | Chromatin; Female; Mice, Inbred C57BL; Phenotype | 2000-12-05 |

Ehleringer, James R. | Implications of CO2 pooling on δ13C of ecosystem respiration and leaves in Amazonian forest | The carbon isotope of a leaf (δ13Cleaf) is generally more negative in riparian zones than in areas with low soil moisture content or rainfall input.
