摘要: Sand dune species were analyzed across two areas included in the “Roman Coastal State Nature Reserve” (Italy): Ostia (O) and Marina di Palidoro (P). Significant variations distribution, dry mass size over gradient from water-edge toward inland between O P observed. Species colonize O, on an average, at 79 m extended along a length of 26 m. PD is 40.8 ± 9.9 plants.m-2. Ononis variegata Elymus farctus have highest (15.4 1.3 plants.m-2), followed by Silene colorata Sporobulus pungens (4.3 3.9 Cakile maritima, Echinophora spinosa, Eryngium maritimum, Ammophila arenaria, Anthemis Cyperus capitatus, Medicago marina Calystegia soldanella (<0.5 with C. having lowest (0.02 plants.m-2). On P, 17 for 46 inland, average 21.5 16.1 S. pungens, E. O. (6.0
