英文摘要	Background and Aims: The card & oacute;n ( Pachycereus pringlei ) is a columnar cactus emblematic of the Sonoran Desert, a region where free-range livestock grazing has been present for centuries, both in the Baja California peninsula and in Sonora. However, the effect of livestock on the population dynamics of the card & oacute;n is unknown. The objective of this study was to analyze whether the exclusion of livestock for nearly three decades had any observable effect on the recruitment probability of the card & oacute;n and on the relationship of the new recruits with two nurse legumes ( Olneya tesota and Prosopis articulata ). Methods: The presence and size of card & oacute;n and the two nurse legumes were recorded in transects. These were distributed under two conditions, with livestock presence and with 27 years of livestock exclusion, in plots established in an arid shrubland in the south of the Baja California peninsula, Mexico. The study analyzed whether there were differences between these two conditions in (i) the recruitment probability of the card & oacute;n, and (ii) the association of new recruits with the nurse legumes. Key results: No differences were found in the recruitment probability between area with livestock and area with livestock exclusion. However, differences were observed in the association between recruited card & oacute;n individuals and nurse legumes, being positive in sites with livestock and absent in sites with livestock exclusion. Conclusions: The lack of differences in recruitment probability between conditions could be due to the influence of processes acting at spatio-temporal scales larger than those of our study. For example, the temporal scale, potentially multi-decadal, of card & oacute;n recruitment pulses or the spatial scale of activity ranges of pollinators, seed dispersers and consumers. Our results underscore the importance of spatio-temporal scale in studying the dynamics of long-lived species in arid regions.
