Do effects of landscape factors on coastal pond macrophyte communities depend on species traits?

► Macrophyte richness and composition were analyzed in non-fragmented dune ponds. ► Area was not a determining factor for macrophyte richness. ► Diversity of habitats influenced total macrophyte, hydrophyte and emergent richness. ► Isolation reduced macrophytes richness. ► Species composition was determined by isolation, diversity of habitats and hydroperiod.
