Potts, Wayne K. | Gong method for capturing shorebirds and other ground-roosting species | In many shorebird studies it is necessary to capture adult birds. While shorebirds can often be trapped on the nest, capturing them away from the nest is usually very difficult and may require expensive equipment. After weeks of failure in our attempts to capture migrant and resident shorebirds in n... | Gong method; Shorebirds; Capture; Ground-roosting | 1979 |

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 |

Ehleringer, James R. | Burning coal seams in southern Utah: a natural system for studies of plant responses to elevated CO2 | In the Burning Hills and Smoky Mountains of southern Utah (USA), coal deposits exposed to the surface have been ignited by lightning and have been burning for periods of years to over a century. We examined one of these sites, where the below-ground combustion of this low-sulfur coal releases gases ... | Coal fires; Elevated CO2; Isotope ratios; Atriplex confertifolia; Salsola iberica; Gutierrezia sarothrae | 1997 |

Ehleringer, James R. | Carbon isotope ratios of Atacama Desert plants reflect hyperaridity of region in northern Chile | Leaf carbon isotope ratios were measured on plants from the coastal portions of the Atacama Desert at Pan de Azucar and Paposo, Chile.

Adler, Frederick R. | Construction of multidimensional clustered patterns | Ecological processes often depend upon the patterning, as well as the absolute density, of resources. In this paper, we develop methods for describing pattern from the perspective of the organism encountering and exploiting the resources, and for reconstructing pattern from the description. | Algorithms; clustered resources; foraging | 1994 |

Olivera, Baldomero M.; Gray, William Robert; McIntosh, J. Michael | Neuronal calcium channel inhibitors: synthesis of ω-conotoxin GVIA and effects on 45Ca-uptake by synaptosomes | We previously described a 27-amino acid peptide neurotoxin from the venom of Conus geographus, wconotoxin GVIA, which inhibits neuronal voltage-activated calcium channels.

Olivera, Baldomero M. | Block of Shaker K+ channels by ĸ-conotoxin PVIIA is state dependent | ĸ-conotoxin PVIIA is the first conotoxin known to interact with voltage-gated potassium channels by inhibiting Shaker-mediated currents. We studied the mechanism of inhibition and concluded that PVIIA blocks the ion pore with a 1:1 stoichiometry and that binding to open or closed channels is very d... | Conotoxins; k-conotoxin PVIIA; Potassium channel blockers; Shaker K+ channels | 1999 |

Farmer, Colleen G. | Dendrobates auratus (green and black poison dart frog). Larval Predation | Dendrobates auratus was intentionally introduced onto the island of O'ahu, Hawai'i in 1932 from Taboga Island, Panama for mosquito control. Phelsuma laticauda was accidentally introduced from Madagascar in 1996 to the University of Hawaii at Manoa. Both species are well established in the Manoa Val... | Dendrobates auratus; Phelsuma laticauda | 2007 |

Farmer, Colleen G.; Carrier, David R. | Integration of ventilation and locomotion in archosaurs | Movements of the pelvis have recently been found to contribute to ventilation in both crocodilians and birds. Alligators have a kinetic pelvis in which the ischiopubic and ischiotruncus muscles rotate the pubic bones ventrally to increase abdominal volume and thereby facilitate inspiration. In birds... | Archosaurs; Theropods; Integration; Ventilation; Pelvic aspiration; Cuirassal breathing | 2000 |

Beckerle, Mary C. | ALP-enigma protein ALP-1 functions in actin filament organization to promote muscle structural integrity in Caenorhabditis elegans | Mutations that affect the Z-disk-associated ALP-Enigma proteins have been linked to human muscular and cardiac diseases. Despite their clear physiological significance for human health, the mechanism of action of ALP-Enigma proteins is largely unknown. In Caenorhabditis elegans, the ALP-Enigma prot... | Actin; Caenorhabditis elegans; Contractility; alp-1 mutants; Z-disks; Kettin | 2009 |

Olivera, Baldomero M.; McIntosh, J. Michael; Yoshikami, Doju | α-Conotoxin GIC from Conus geographus, a novel peptide antagonist of nicotinic acetylcholine receptors | Many venomous organisms produce toxins that disrupt neuromuscular communication to paralyze their prey. One common class of such toxins comprises nicotinic acetylcholine receptor antagonists (nAChRs). Thus, most toxins that act on nAChRs are targeted to the neuromuscular subtype.
