Zonation of vegetation on lacustrine coastal dunes: effects of burial by sand

摘要: More than 50 years ago it was proposed that zonation of major plant species on coastal dunes determined by salt spray. Here, we argue against this hypothesis because (i) concentrations rarely exceed toxic levels; (ii) high precipitation in temperate latitudes washes the off plants; (iii) spray events occur late autumn and winter when plants are dormant; (iv) also occurs lacustrine dunes. Instead, show evidence may be caused burial distribution correlated with sand deposition were eliminated exceeded their limits tolerance, thus creating zones different species. We conclude regions among most important factors zonation, while play a secondary role; single environmental cannot determinants phenomenon as complex zonation.
