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. Thi... | Bird lice; Campanulotes compar; Coexistence; Colonization; Columba livia; Columbicola columbae; Competition; Dispersal; Parasite; Phoresis; Specificity; Pseudolynchia canariensis; Phthiraptera | 2008 |

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 |

Coley, Phyllis D.; Kursar, Thomas A. | Food quality, competition, and parasitism influence feeding preference in a neotropical lepidopteran | We surveyed Lepidoptera found on 11 species of Inga (Fabaceae:Mimosoideae) co-existing on Barro Colorado Island, Panama, to evaluate factors influencing diet choice. Of the 47 species of caterpillars (747 individuals) recorded, each fed on a distinct set of Inga. In the field, 96% of the individuals... | Competition; Electivity; Gelechiid; Herbivore growth; Fabaceae; Inga; Leaf expansion; Leafing phenology; Lipidoptera; Panama; Parasitism; Plant quality | 2006 |

Davidson, Diane W. | Granivory in the Chihuahuan Desert: interactions within and between trophic levels | We investigated the effects of Chihuahuan Desert granivores on three seasonal classes of plant resource species, the effects of these resource classes on one another, and the ways in which interactions through plant resources affect the abundances of seed consumers. At our study site, three seasona... | Annual plant; Ant; Competition; Community; Desert; Ecosystem structure; Experiment; Granivore; Indirect interaction; Rodent; Population cycles; Seed predation | 1985 |

Davidson, Diane W. | Preliminary study of seed predation in desert and montane habitats | Multifactorial experiments in which domestic seeds in shallow glass containers were distributed in desert and montane habitats provided data on identity of seed predators (whether rodents or ants), spatial and temporal pattern of their foraging activities, and their preferences for sizes and species... | Ant; Competition; Granivory; Predators, Seed; Rodent; Seed selection | 1975 |

Davidson, Diane W. | Species diversity and community organization in desert seed-eating ants | Patterns of species diversity and community organization in desert seed-eating ants were studied in 10 habitats on a longitudinal gradient of increasing rainfall extending from southeastern California, through southern Arizona, and into southwestern New Mexico. Local communities of harvester ants... | Ants; Arizona; California; Communities; Competition; Desert Granivores; Diversity; Insects; New Mexico; Novomessor; Pheidole; Pogonomyrmex; Resource allocation; Veromessor. | 1977 |
