Based on three decades of field experience in southwest Asia, southern
Africa, and the southwest United States, the author summarizes the major
adaptations of plants to desert dunes. This integrative study of plant
and diaspore morphology, reactive growth, life cycles, and environmental
factors explains and predicts plant distribution. Many kinds of dune
syndromes, plant case studies and vegetation transects are discussed and
illustrated to clarify the significance of adaptations to specific
habitat factors. Although the focus is on vascular plants, the
development of microbiotic soil crust, its function, and its composition
are discussed as well.
