Abstract
Plankton are transported onshore, providing subsidies of food and new recruits
to surf-zone and intertidal communities. The transport of plankton
to the surf zone is influenced by wind, wave, and tidal forcing, and whether
they enter the surf zone depends on alongshore variation in surf-zone hydrodynamics
caused by the interaction of breaking waves with coastal morphology.
Areas with gently sloping shores and wide surf zones typically have
orders-of-magnitude-higher concentrations of plankton in the surf zone and
dense larval settlement in intertidal communities because of the presence of
bathymetric rip currents, which are absent in areas with steep shores and narrow
surf zones. These striking differences in subsidies have profound consequences;
areas with greater subsidies support more productive surf-zone
communities and possibly more productive rocky intertidal communities.
Recognition of the importance of spatial subsidies for rocky community dynamics
has recently advanced ecological theory, and incorporating surf-zone
hydrodynamics would be an especially fruitful line of investigation.
