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 |

Ailion, David Charles | NMR determination of structural domains in NaCN | Measurements of the first- and second-order quadrupole energy-level shifts are performed in a 23Na NMR experiment in a single crystal of NaCN. Twelve orthorhombic domains are found below the phase transition at 15°C. They consist of six pairs of domains with each one oriented by an angle 2/3 rel... | NMR; Nuclear magnetic resonance; Crystals; Structural domains | 1980 |

Miller, Joel Steven | Optical and electron-energy-loss studies of the monomeric and dimeric phases of decamethylferrocenium tetracyanoquinodimethanide, (DMeFc)(TCNQ) | The optical properties of the two crystallographic phases of 1:l decaniethylferrocenium tetracyanoauinodimethanide, (DMeFc)(TCNQ), have been measured from 0.1 to 10 eV. One phase consists of isolated paramagnetic TCNQ anion monomers while the other contains isolated diamagnetic dimers. The spectru... | Ions; Spectrum | 1980 |

Golden, Kenneth M. | Sea ice studies in the Weddell Sea aboard USCGC Polar Sea | Our purpose was to investigate several of the characteristics of Weddell Sea pack ice that may affect the relative roles of dynamics and thermodynamics of pack ice development in this region. The total pack ice production and the movement of pack ice from its source area in the Weddell Sea is part... | Floes.; Salinity; Formation | 1980 |

Davidson, Diane W. | Some consequences of diffuse competition in a desert ant community | Exploitative and interference competition are investigated in detail in a community of six coexisting species of granivorous desert ants . A linear model that includes both direct and indirect competitive interactions is used to predict positive or negative correlations in the abundances of com... | Ants; Arizona; California; Coexistence; Communities; Density specialization; Desert granivores; Resource partitioning | 1980 |
