"excerpt": "Here we show that oyster reefs have combinations of geometric variables that maximize recruit survival, which is a key factor influencing oyster reef growth and persistence. Using three-dimensional habitat designs that capture the full spectrum of natural oyster reef architectures, as well as a geometric theory that links habitat surface area, fractal dimension and height, we show that oyster settlement and survival are greatest at particular combinations of fractal dimension and height that minimize predation.",
