Spatial genetic structure of <i>Arundinaria appalachiana</i> (hill cane), an upland bamboo species endemic to the southern Appalachian Mountains, USA

Arundinaria appalachiana persists through clonal growth alone, forming extensive, ancient genets in the absence of sexual reproduction. This clonal longevity enables persistence, but the lack of genetic renewal raises concerns about long-term viability in changing environments. Our findings highlight the importance of understanding spatial genetic structure in clonal plant populations and its consequences for conservation planning.
