Shark-mediated Trophic Cascade in Fiji - Paper!

Reeftop predators: Blacktip Reefie and Bluefin Trevallies - great pic by Allen!


Read this.
It illustrates how Reef Sharks influence the behavior of seaweed grazers and consequently, consistently influence the size and distribution of seaweed on the back reef of Votua, i.e. right in front of the iconic Eco Café, home of Fiji's very best wood-fired pizza, friendliest service and most beautiful smiles.

Well done Doug and Mark.
I must really say that this is science at its best, with observations leading to questions and then a proper hypothesis that is being rigorously tested, exactly as it should be. What I also like, is that the authors refrain from unduly exaggerating and generalizing the role (and trophic ranking!) of Reef Sharks but instead attribute the cascading effects to the specific situation alone - again exactly as it should be.

Required reading - story here, nice synopsis here.
