Description :
Studies of dune vegetation patterns have emphasized 2 structuring agents : local environmental gradients that shape the prominent zonation of coastal plant species, and disturbance patches initiated by overwash during coastal storms. For dune systems of 2 barrier islands in the Georgia Bight, the AA. investigate how the interplay of these 2 conceptual frames generate patterns in 1) longitudinal (along-shore) and transverse (across-shore) compositional variability and 2) the arrangement of species along transverse gradients. They discuss the benefit of incorporating a complex adaptive-systems framework into the reductionist methodologies invoked in field-based biogeographical studies.
