Short summary
This study determines the diversity of pollen morphotypes of Atriplex halimus (Amaranthaceae) along a large-scale climatic gradient. Occurrences of 10 pollen grain shapes were quantified at seven climates across a humid-to-hyperarid gradient. We discuss how the evolutionary effects of climate gradients on pollen morphology and variability in dryland induce a high level of specialization to maximize trade-offs between adaptation to severe ecological conditions and pollination efficiency.
