Abstract
Plants with anciently fragmented population structures may show distinct molecular ecological characteristics compared to recently fragmented populations, with important implications for conservation genetic management. I applied field-based experiments in combination with microsatellite genotyping to investigate genetic structure, pollen dispersal and mating patterns in E. caesia, a tree endemic on granite outcrops. I found that unique genotypes and localised clonality were present in most stands. Purging of genetic load and pollination by honeyeaters may have played a role in the species persistence, with the relative importance of these influences potentially varying among populations or across the evolutionary history of populations.
