Resumen

Questions: Spatial pattern analysis may be used to derive hypotheses on the processes that shape plant communities. Do different mature semidesert communities exhibit the same major spatial patterns, suggesting that similar processes shape them?. Location: Nine localities in the Bolivian Andes. Methods: We mapped all woody individuals at each locality. We performed uni-, bi-, and multivariate spatial analyses of nine Andean, mature semiarid plant communities to test for similarity in spatial patterns. Results: We found that the nine communities exhibited, in most of the main spatial pattern attributes, close similarities (community aggregation, importance of plant interactions, life form differences, etc.). Some peculiarities were likely due to differences in life form or site history. Conclusions: At least for Andean semiarid communities, the complete analysis of a representative plot conveys reliable information on spatial relationships and, hence, on potential underlying mechanisms. This shows that the use of 1–2 representative plots can be used to extrapolate to similar communities within a given region. Our results can be used as a plausible hypothesis to be tested in other zones of the planet.
