Seed burial effect on species presence along a mid-Atlantic beach

摘要

The importance of seed burial to species presence on mid-Atlantic beaches was studied on Currituck Bank, North Carolina. Sand accretion and seed depth were measured and compared with potential shoot length and buried shoot length of dominant beach, foredune, and sand-flat species. Excessive seed burial plays an important role in the rarity ofUniola paniculataL. andSpartina patens(Aiton) Muhl. on the beach.
