Saguaro (Carnegiea gigantea) densities and reproduction over the northern Sonoran Desert

Authors(s) and Affiliation(s)



The A. proposes to determine whether there are geographic or regional patterns in population density and reproductive density in saguaro populations. He establishes how saguaro density varies over the American portion of its range, and whether it is summer rainfall and climate, or the availability of nurse cover (which is related to summer rainfall) that is linked to density. He distinguishes between these confounded variables. He also relates reproductive stem density (e.g. reproductive effort per area) to vegetation and climate variables. The A. considers these questions from a regional perspective using data from 30 sampled populations over Arizona, U.S.A.
