Davidson, Diane W. | Competition and the structure of granivore communities | We trace the development of our investigations of granivory in desert ecosystems, illustrating the synthesis of the comparative and experimental approaches and noting the essential contributions of both. In the process, we also call attention to several major difficulties inherent to experimentatio... | Granivory; Competition; Desert Ecosystems; Competitive investigations; Experimental investigations | 1980 |

Seger, Jon | Conditional relatedness, recombination, and the chromosome numbers of insects | If two polymorphic loci are out of phase equilibrium, a homozygote at one of these loci is more highly related to its kin, at the other locus, than is an equivalent heterozygote. As a result, selection can favor (1) phenotypic responses to relative heterozygosity, and (2) increased recombination bet... | Coefficients of relatedness; Conditional relatedness | 1983 |

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 | Contryphan is a D-tryptophan-containing Conus peptide | In this report, we document for the first time the occurrence of D-tryptophan in a normally translated polypeptide, contryphan. The peptide, isolated from the venom of the fish-hunting marine snail Conus radiatus, produces the "stiff-tail" syndrome in mice. | Conotoxins; Contryphan; D-tryptophan; Conus peptides; Conus radiatus; Stiff-tail syndrome | 1996 |

Olivera, Baldomero M.; Gray, William Robert; Yoshikami, Doju | Conus geographus toxins that discriminate between neuronal and muscle sodium channels | We describe the properties of a family of 22-amino acid peptides, the μ-conotoxins, which are useful probes for investigating voltage-dependent sodium channels of excitable tissues. The μ-conotoxins are present in the venom of the piscivorous marine snail, Conus geographus L. We have purified even... | Conus geographus; Venom; Conotoxins; Sodium channels; Neurotoxins | 1985 |

Olivera, Baldomero M.; McIntosh, J. Michael | Conus peptides as tools for the neuroscientist | Recombinant DNA technology has had a powerful impact on understanding receptors and ion channels, the key components in the nervous system that are involved in intercellular communication. Cloning genes encoding these proteins has revealed that for every receptor and ion channel type, multiple molec... | Conus peptides; Conotoxins | 1993 |

Olivera, Baldomero M. | Conus peptides: biodiversity-based discovery and exogenomics | The venoms of the ~700 species of predatory cone snails (genus Conus) are being systematically characterized. Each Conus species contains 100-200 small, highly structured venom peptides (colloquially known as conotoxins), which are synthesized and secreted in a venom duct (for overviews, see Refs. ... | Conotoxins; Conus peptides; Exogenomics | 2006 |

Olivera, Baldomero M. | Conus peptides: phylogenetic range of biological activity | The major function of the venoms of the predatory marine snails belonging to the genus Conus is to paralyze prey. Thus, the venom of each Conus species acts on receptors and ion channels of the prey; previous studies suggested much less activity on homologous receptor targets in more distant taxa.... | Conus peptides; Conopeptides; Conotoxins | 1992 |

Olivera, Baldomero M. | Conus venom peptides, receptor and ion channel targets, and drug design: 50 million years of neuropharmacology | The predatory cone snails (Conus) are among the most successful living marine animals (~500 living species). Each Conus species is a specialist in neuropharmacology, and uses venom to capture prey, to escape from and defend against predators and possibly to deter competitors. An individual cone... | Conotoxins | 1997 |

Goller, Franz | Coordination and synergism between visual and vocal display in the brown-headed cowbirds | Sexually selected acoustic signaling is accompanied by visual displays in many birds. The motor integration of visual and vocal displays has not been extensively studied.

Carrier, David R. | Coupled evolution of breathing and locomotion as a game of leapfrog | Because the increase in metabolic rate related to locomotor activity places demands on the cardiorespiratory apparatus, it is not surprising that the evolution of breathing and of locomotion are coupled. As the respiratory faculty becomes more refined, increasingly aerobic life strategies can be exp... | Evolution; Coupled evolution; Breathing; Locomotion; Cardiorespiratory apparatus | 2006 |
