    Pawpaws prevent predictability: A locally dominant tree alters understory beta‐diversity and community assembly by Anna C. Wassel, Jonathan A. Myers

    Published 2025-01-01
    “…Together these results suggest that pawpaw increases the importance of stochastic relative to deterministic community assembly at local scales, likely by decreasing overall numbers of individuals and increasing random local extinctions inside patches. Our findings provide insights into the ecological processes by which locally dominant tree species shape the assembly and diversity of understory plant communities at different spatial scales.…”
