Davidson, Diane W. | Foraging ecology and community organization in desert seed-eating ants | Granivorous ants in the southwestern deserts of the United States are characterized by species-specific colony foraging behaviors that determine their efficiencies at utilizing seeds from different density distributions. Workers search for food either in groups or as individuals, and these feedin... | Ants; Arizona; California; Coexistence; Communities; Density specialization; Desert granivores; Foraging strategies; Insects; New Mexico; Resource partitioning | 1977 |

Davidson, Diane W. | Size variability in the worker caste of a social insect (veromessor pergandei mayr) as a function of the competitive environment | Worker size polymorphism in colonies of Veromessor pergandei, a granivorous desert ant, is inversely related to the intensity of interspecific competition in the habitat for seven ant communities in the deserts of southern California and southern Arizona. Seed size preferences are positively corr... | Ants; Arizona; California; Coexistence; Communities; Density specialization; Desert granivores; Foraging strategies; Resource partitioning; Size | 1978 |

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 |

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 |
