Fragmentation reduces population sizes, increases isolation between habitats and can result in restricted dispersal of pollen and seeds. Given that diploid seed dispersal contributes more to shaping fine‐scale spatial genetic structure (SGS) than haploid pollen flow, we tested whether fine‐scale SGS...
