Nurse plant relationships of columnar cacti in Arizona

Auteur :
PARKER, K. C.

Description :
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 closely linked to patterns of overall vegetation change than to population fluctuations of a particular species that acts as a nurse.
