This easy to follow paper suggests that may indeed be the case in some areas. Turtle populations are thriving in many areas (including The Bahamas), due to extensive conservation initiatives as well as overfished top predators (such as sharks). A result may be decimated seagrass ecosystems under certain circumstances. This is exactly what FIU graduate student is examining in her research program. She heads back to Abaco soon to check on her experiments, and I am excited to see what she finds.
