The ultimate conservationists written large in the landscape. It speaks so much about the First Nation People of the South Eastern Coast of the United States - more probably, the whole of the Seaboard of North America.Learning from the past.
An interdisciplinary team of scientists studying thousands of oyster shells along the Georgia coast, some as old as 4,500 years, has published new insights into how Native Americans sustained oyster harvests for thousands of years, observations that may lead to better management practices of oyster reefs today.
Their study, led by University of Georgia archaeologist Victor Thompson, was published July 10 in the journal Science Advances.
The new research argues that understanding the long-term stability of coastal ecosystems requires documenting past and present conditions of such environments, as well as considering their future. The findings highlight a remarkable stability of oyster reefs prior to the 20th century and have implications for oyster-reef restoration by serving as a guide for the selection of suitable oyster restoration sites in the future.
Shellfish, such as oysters, have long been a food staple for human populations around the world, including Native American communities along the coast of the southeastern United States. The eastern oyster Crassostrea virginica is a species studied frequently by biologists and marine ecologists because of the central role the species plays in coastal ecosystems.
