As part of our Marine Invertebrate Zoology class (Spring 2012 - Graduate Program in Marine Biology - College of Charleston), we have attempted to document the marine invertebrate species at 3 different local sites: the Folly Beach groin
, Ft. Johnson
, and Murrells Inlet
. All three of these sites have been surveyed in the past, and we aim to document the changes in community composition at each location.
Significant findings at each site include:Folly Beach
- Community composition by phyla was similar between historical and current surveys, but species differed.
- Two invasive species were identified in the current survey that were not found in the historical survey.
- Number of species per phyla similar between historical and current surveys in all but annelida and arthropoda
- Of the 58 species found historically and 20 found in 2012, only 8 were the same. Differences are likely due to methodology and community succession.
- Similar species were found in the area between historical and current surveys, but substrate type impacts the community composition.
- Many limitations existed in comparing the two studies due to ambiguous notes on historical methods and exact sampling sites.
