Community Dynamics
This photograph was taken on March 21, 2018, at 9:34AM at Fort Fisher Beach, North Carolina, and depicts a coquina. A coquina is a man- made structure composed of shells that have been crushed together to act as a rock. This structure is used to prevent erosion of beaches by collecting sand. Not only does this structure act to protect the coastal ecosystem from erosion, but it also acts as a model of community dynamics. Algae appears to be growing on the structure. Because no community previously occupied the man- made shell structure, this is an example of primary succession. Additionally, this image depicts zonation. Species like seagulls and sand crabs live above the high- tide line. Species like the algae seen in this picture occupy the intertidal zone, and different species of fish occupy the below low- tide lines. All of these species live in the coastal community.
