Comparative Analysis of Load Adaptation Strategies in Columnar Cacti and Hardwood Trees

Abstract: “Cacti are different.” This sentence holds true for many aspects of the functional morphology and anatomy of cacti in comparison to other perennial plants. The biomechanical adaptations, especially of tree-like columnar cacti, seem to be unique. The scope of this small review is to elucidate some of their specific load adaptation strategies and how they deviate from — or are similar to — typical hardwood trees.
