Mixed hardwood seedling mortality is associated with canopy and herb-layer composition in a broad-scale transplant experiment ... mortality and canopy Acer rubrum basal area was driven by particularly low autumn seedling mortality, suggesting that differences in canopy phenology (e.g. leaf senescence), may be important drivers of seedling mortality. Additionally, the significant positive relationship between total seedling mortality and ...
