Patterns of Seed Dispersal in Coastal Dune Plant Communities

Seed dispersal is a key determinant of species distribution, although it still unclear how contributes to assembly in plant communities. We linked patterns seed coexisting investigate the role process. focused on 19 foredune community, classified as “foredune foundation species”, “semi-fixed dune species,” and “alien species”. The number seeds dispersed by was monitored monthly 25 plots for 12 months. Then we compared both strategies phenology among species. Foredune species, semi-fixed dune, alien used same strategies, with exception hemerochory, which prevalently three groups differentiated season: were early late dispersers, respectively (spring vs. summer), while summer. Seasonal differentiation may play more important process than vectors. Shifts seasonality due climate change influence timing provide different colonization opportunities.
