In poor, well‐drained sandy soils, we observed the coexistence of more closely related species, suggesting that shared evolutionary history influences which seedlings survive under these restrictive conditions. Contrary to expectations, flooded areas harbored more distantly related species, likely because pathogens and other natural enemies limit the ...
