Scientists have discovered changes in DNA patterns for juvenile lemon sharks that lived through a dredging event to construct a commercial marina in Bimini, Bahamas.
According to the Florida International University, dredging the waters off Bimini for a marina undoubtedly affected the environment. It also left an indelible mark at the molecular level on young lemon sharks in a nearby nursery.
Andria Beal, a Ph.D. candidate in the Institute of Environment, led the first of its kind study to uncover one of the greatest mysteries – how environmental stressors impact sharks.
