Patterns of association of three columnar cactus species with potential nurse plants and rocks are examined in Organ Pipe Cactus National Monument, Arizona. The results suggest that a landscape scale, population dynamics of columnar cacti are more
This paper demonstrates the use of the kriging method for mapping and evaluating precipitation data for the State of Arizona. Using 158 rain gauge stations with 30 years or more of record, the precipitation over the state has been modeled

Les AA. examinent à partir de photographies prises en 1892, 1969 et 1976 l'impact de l'utilisation du sol sur les groupements végétaux de chaque côté de la frontière Arizona-Mexique.
Les surfaces géomorphologiques du Piédmont des Mohave Mountains (Arizona), se sont formées sur des dépôts sédimentaires datant du Miocène moyen au Pléistocène et sur des ganglomérats d'origine locale. Les surfaces sont interprétées comme des
