• Zonation is a vertical banding of the organisms living on the rocky coastline.
• These distinct bands occur in part from many complex physical and biological factors that effect marine organisms.
Spray or Splash Zone
High Tide Zone
Middle Tide Zone
Low Tide Zone
Mostly shelled orgs
Many soft bodied orgs and algae
Biotic factors affecting organisms living in the intertidal zone:
• Competition for space and food• Predation• Reproduction• Substrate settlement preference• Osmoregulation (dessication)
Abiotic factors affecting organisms living in the intertidal zone:• Salinity• Temperature • Air and light exposure• Tidal flow• Waves and current action• Substrate• Wind direction and strength• Dissolved O2• Storms• Natural Disasters
